The world’s brightest Micro LED display panel is about to debut

After Samsung released the 146-inch modular MicroLED TV product “The Wall” at the CES 2018 conference in January this year, many manufacturers have displayed MicroLED planar products at major exhibitions.

At the 2018 International Conference on Display Technology (ICDT 2018) held in April, Taiwanese manufacturers Playnitride and JDC exhibited Micro LED displays. In addition, at the 2018 International Display Conference (Display Week 2018), which just kicked off on May 20, Sweden’s leading μLED device manufacturer glō (invested by Google) and Helian Optoelectronics jointly demonstrated the world’s brightest Micro LED display panel .

The micro LED TV displayed by Samsung at CES 2018 is a micron (μm) LED self-luminous TV. Because it is arranged in a rectangle, it is closer than the traditional LED circle. In addition to the material relationship, it also improves the luminous efficiency. The life of the light source and reduce power consumption, but this solution is a marketed version. The on-site assembly is a 146-inch full-screen LED TV, which is by far the largest model in the home TV field.

The Micro LED display exhibited by Nitronics at ICDT 2018 amazed the visitors present. It is divided into three colors: white light, green and full-color display. Among them, the 0.89″ display is applied to the watch, with a ppi of about 169, and uses a blue LED chip + Phosphor color scheme; there is also a 0.8″ display, with a ppi increased to 230, and a monochrome scheme with a green LED chip; A full-color 0.89″ display, using RGB LED chip combination, about 103 ppi

What Helian Optoelectronics exhibited at ICDT 2018 is a Micro LED display with Silicon as the backplane. The current display technology has been developed to 0.7″, and the display size can reach 4K resolution. Although it is a monochrome display, the smallest Pixel Size can reach 3.74 μm, with high display effect

And this time at Display Week 2018, the Micro LED display panel displayed by glō and Helian Optoelectronics adopts the Micro LED (10μm) developed and integrated by glō, and cooperates with JDC’s new silicon-based backplane JD67E2, which can provide high brightness and contrast. Display, which is beneficial for applications in watches, mobile phones, tablets, displays (HUD) and augmented reality (AR) products

OLED may currently dominate, but Micro LED, which combines many advantages, has the potential to become the next generation of displays. Jeffrey Li, application director of JDC, believes that they have foreseen the rise of Micro LED and have the ability to help customers develop a variety of new products

He also said that JD67E2 proved our ability in the μLED field. We are excited to deliver what the industry has been waiting for – Silicon compliant for Micro LEDs. Our Micro LED backplane technology can be customized on a per-project basis, allowing us to manufacture special silicon for applications such as low-power AR headsets, automotive headlights, and more

The full-color JD67E2 has a resolution of 1920 x 1080, a pixel pitch of 8um, and provides excellent current uniformity through proprietary current source pixels. Uniformity across the array is better than 1%

In addition to increasing brightness and contrast, JDC pixel-by-pixel pulse width modulation technology is ideal for Micro LEDs because digital switching allows for precise and consistent coloring; a single on-state current will provide a single stable color. On the contrary, the analog driving scheme provides different current levels through the Micro LED, which will cause the wavelength to change, and thus the color shift

Although many manufacturers have exhibited Micro LED display products, there is still a long way to go before commercialization. According to LEDinside analysis, the cost of Micro LED display panels is still much higher than that of traditional LCD or OLED display panels. The current challenges include how to make LEDs into the micron level, and how to transfer micron-level LEDs to the backplane to make pixels in large quantities, all of which test the technical process and production capacity of the manufacturer

Because the price of mainstream 55-65-inch LCD TVs at this stage is too expensive. The cost of LCD and OLED can be reduced to a level acceptable to consumers. In the short term, the cost and selling price of Micro LED TV will be difficult to compete in this field. But the market above 100 inches is another matter

Due to the sharp increase in the production cost of LCD and OLED panels above 100 inches at the current stage, Micro LED TVs are given an opportunity to enter. When the technology and production process of Micro LED become more and more mature in the future, there will be an opportunity to cut into the mainstream size.

LED display technology has advanced rapidly in recent years, transforming the way we interact with digital content and pushing the boundaries of visual communication. As we look to the future, several key trends are shaping the evolution of LED display technology and paving the way for new possibilities and innovations.

By staying abreast of these key trends and embracing new technologies, businesses and organizations can harness the power of LED displays to create captivating, memorable, and impactful visual experiences for their audiences.

Principles and applicable conditions of LED display steel structure hoisting scheme!

Soft LED Display display steel structure installation is a relatively complex and comprehensive technology with many contents and a wide range. Combined with some steel structure projects, the basic principles and applicable conditions of steel structure hoisting scheme design are expounded, and the feasibility of conventional installation methods and corresponding technical measures are summarized.

With the continuous development of science and technology, the shape and structural form of steel structures are becoming more and more complex, which brings new challenges to the design and construction of steel structures. For example, Olympic venues represented by “Bird’s Nest” and “Water Cube”, as well as influential steel structure projects such as the National Center for the Performing Arts, the site of the new CCTV station, the Guangzhou TV Tower, and the stupa of Famen Temple, have not only innovated and developed in design , At the same time, new achievements have been made in steel structure installation technology. Many mature and advanced technological methods have gradually become construction methods, which have played a role in promoting the development of the steel structure industry.

Due to market reasons, steel structure installation accidents and violations occur from time to time, causing unnecessary economic losses and social impacts. In order to further improve the overall level of steel structure construction and promote the development of the industry, in addition to strengthening construction site management, steel structure construction should also conduct research and summary in terms of construction organization design, schemes, technical measures, etc.; vigorously promote new technologies and new processes; Features, choose advanced, reliable and economical construction scheme.

Basic principles of steel structure hoisting scheme for led display

Policy-Based on the drawings and norms as the criterion, strictly implement the relevant national safety production regulations.

Reliability – Adhere to safety first, ensure the feasibility of program implementation and increase its reliability. No matter which method is adopted, it is first necessary to consider whether the program has successful precedents and supporting equipment, otherwise, program demonstration must be carried out. According to the structural characteristics, the construction check calculation is carried out to prove whether the stability of the structure, the stress and deformation of the members meet the requirements during the construction stage of the method. Whether the mechanical equipment used can meet the installation requirements. Whether the construction site conditions are met, such as whether the civil construction environment and surrounding structures restrict the implementation of the plan, etc.

Advancement——With the development of science and technology, new techniques, new technologies and new equipment in the field of structural installation emerge in an endless stream. For example, the advent of large-tonnage cranes, computer synchronous control of overall lifting and sliding technology have added a new chapter to structural installation. Especially for large-scale steel structure projects, when site conditions and structural forms permit, new technologies and new processes should be vigorously promoted; the amount of high-altitude operations should be reduced as much as possible, and the installation efficiency of steel structures should be continuously improved.

Economical – A good installation plan should be simple in method, appropriate in measures, high in efficiency, low in construction cost, wide in application range, and stand review and test. Therefore, we must adhere to the principle of program comparison, conduct technical and economic analysis, and choose a program with a short construction period and low cost.

Applicable conditions for the steel structure hoisting scheme of the led display

Due to the inconsistency of architectural shapes and structural forms, and the wide variety of construction site conditions, it can be said that there is no one construction method or scheme suitable for the installation of any steel structure project, so each installation method has its own supporting conditions.

Commonly used installation methods for grid structures include: high-altitude bulk installation method, strip and block installation method, structural sliding method, support frame sliding method, overall hoisting method, and overall lifting method.

Consider according to the process method: understand the characteristics of the structure form, structure weight, installation height, span, etc., and use mature and advanced installation processes as much as possible in combination with the actual situation on site.

Consider the lifting equipment: first, choose your own equipment, make full use of the on-site lifting equipment, and then rent the nearest one. General situation: When the number of components is small, truck-mounted cranes are often used; small and medium-sized truck-mounted cranes are mostly used for portal frame hoisting; when the installation period is long, the installation height and the radius of gyration are large, crawler cranes are more economical than truck-mounted cranes; overall Hydraulic synchronous lifting (jacking) devices are mostly used for hoisting and sliding; tower cranes are generally used for middle and high-rise steel structure installation; gantry cranes and bridge erecting machines are mostly used for ordinary bridge installation.

Flip-chip construction – the flip-chip method is a special installation process that first goes up and then down. It is suitable for structures with large height-to-width ratios, such as steel towers, masts and other structures. In the case that it is difficult for a conventional crane to be hoisted close by, the upside-down method is generally used. When adopting this method, it is necessary to focus on the overall stability of the structure and the stability of the equipment itself during the installation process, and reliable support and stability measures must be taken.

Structural slip method – The structural slip method has been developed to adopt hydraulic pusher and computer synchronous control technology, which is one step more advanced than the grid slip method in the past. Its applicable conditions are: first, due to the limitation of site conditions, cranes and support frames cannot be installed in the span; second, the structural support conditions are conducive to the laying of sliding tracks; third, the strength and strength of the sliding unit structure determined by calculation The stiffness meets the requirements; fourth, understand the structural support form and fixing method; fifth, the longer the longitudinal slip route, the higher the efficiency.

Support frame sliding method – its applicable conditions are to occupy the inner space of the span, the installation height is low, the structure area is large or the longitudinal length is long. First, when the installation height is below 15 meters, ordinary fastener-type steel pipe scaffolding or bowl-shaped scaffolding can be used as the support frame; second, when the frame body is high and the load-bearing capacity is large, the steel support frame should be used. No matter which scheme is adopted, in addition to the requirements of the code, the design and calculation should also consider the horizontal dynamic load, and if necessary, add large diagonal braces to improve its overall stability.

Overall lifting method – the overall lifting method currently mostly uses computer synchronous control and hydraulic lifting equipment developed by Tongji University. This process gradually replaces the core-through motorized lifting and jack lifting schemes. The equipment is light and the technology is advanced. Its applicable conditions are: first, it occupies the space inside the span; second, the installation height is high; third, the components are heavy; fourth, it is limited to vertical hoisting and cannot be displaced horizontally. That is, the higher the installation height and the heavier the lifting weight, the better the effect.

Indigenous method of hoisting – Indigenous method of hoisting is to use single-angle poles, herringbone frames, winding machines, pulley blocks, etc. as lifting equipment for structural hoisting. It is suitable for projects with heavy components, small quantities and high installation heights. Due to the increasing number of large-tonnage lifting equipment and advanced installation techniques, there are fewer and fewer local methods of hoisting.

Rotation method construction – this method is mainly used for bridge installation. Due to the influence of railway, highway traffic, and special environments such as mountains, rivers and ditches, when other bridge erection methods are restricted, the rotation method is often used for construction.

Overall hoisting method-it is basically similar to the overall hoisting method, except that the lifting equipment is different, and it is suitable for small and medium-sized structure installation. In the early days, multiple single-legged poles or herringbone frames, hoists, pulley blocks and cable wind systems were used for large-tonnage hoisting. Now, because there are many large-tonnage cranes, several cranes are selected for centralized lifting and installation for small and medium-sized projects according to needs.

Talking about the Visual Distance Calculation of Small Pitch LED Display

Unlike the commonly used electronic products that are viewed at close range, such as mobile phone screens, laptop screens, etc., LED displays are suitable for long-distance viewing. For the same LED screen product, the viewing distance will determine whether the display effect that the viewer sees is clear or not.

The theoretical resolution of the human eye is 20 arc seconds, but due to the distribution of photoreceptor cells and their own defects, the actual resolution of visible light is 1 arc minute, and objects wider than 1 arc minute are blended with the background.

For example, let’s calculate the “point distance limit” that the human eye can see at 1 meter. You can simply understand it as the smallest point diameter or the smallest straight line diameter that your eyes can see at 1 meter ( smaller than the above size, then they will dissolve into the background), or it can also be understood as the minimum distance that can separate two small points (line diameters), if it is smaller than the above distance, then they will dissolve into a point or a straight line.

1 arc minute = 1/60 degree = (2π/360) / 60 = 0.000291 radians Therefore, the minimum point distance that can be seen at 1 meter (approximately equal to the arc length): arc length = arc * radius = 0.000291*1000mm = 0.291 mm Now let’s do the actual calculation. Let’s use a 16:9 high-definition (resolution 1920×1080) flat-panel TV screen to illustrate:

1 meter distance corresponds to 25.237 inches

2 meters distance corresponds to 50 inches

3 meters distance corresponds to 75 inches

4 meters distance corresponds to 100 inches

5 meters distance corresponds to 125 inches

The reverse deduction of the formula is the formula for calculating the best viewing distance in terms of the viewing distance of the LED display.

The best viewing distance is defined as: in the normal direction of the front of the screen, the minimum distance between the two closest adjacent pixel light-emitting points cannot be distinguished. It means that you can watch high-definition images in the visible area greater than the optimal viewing distance. At this time, you will not feel the graininess of the screen, because the resolution limit of your eyes has been reached.

The resolution of the human eye mentioned above is 1 arc minute, which is obtained by testing the black bars on a white paper under very ideal conditions (sunny and bright enough, and no reflection), and it is obtained by people with particularly good eyes. In fact, the average person’s eyes are not that good, and the results will be biased if this experiment is done under dim light, the human eye is highly sensitive to this pattern, which will be 3 to 5 times more sensitive to the white dots on a black background.

In addition, for a point light source in the dark (if the brightness of the point light source is the same, for example, double star observation in astronomy), the resolution of the best person can reach 2 arc minutes, and the resolution of the average person in this case is 3- 5 cents. If the viewer is nearsighted, the resolution of distant objects will be lower.

Therefore, we calculate the ideal situation (according to greater than 1 angular minute), people standing in the area between S1 and S2 can watch all the images without losing information, and the best viewing distance is at the golden section point Sr. Perfect balance between distance and vision.

1 minute of arc＝1/60 degree＝(2π/360)/60＝0.000291 radian; usually take the value of 0.000294 radian, 1/0.000294=3400, get the formu

Maximum viewing distance S2=3400P; P(mm)——LED pixel pit

Open your mind, let’s see what they are doing with LEDs?

LED lights can also be installed on shoes

A few days ago, Sony PlayStation announced that it teamed up with NBA star Paul George and Nike to create a PS-themed basketball shoe—Nike PG-2 PlayStation Colorway.

It can also be seen from the name that this Nike shoe that incorporates the PS theme has the button elements of the PS4 handle on the side, and the PlayStation logo with the LED light source on the tongue. It supports three display modes, which can be turned on and off, which is very dazzling. cool. There is also an exchange code that can be exchanged for the Paul George PS4 theme behind the left shoe.

In addition to PS elements, the shoe itself uses Nike’s signature ZOOM AIRBAG air cushion, and the bottom is designed with a rubber outsole, which has better durability and multi-site adaptability.

Paul George said that his father bought him a PS2 console for Christmas when he was a child; and Nike sneakers were a dream version of him when he was a child. Now, he finally has the chance to combine two of his favorite things into one sneaker with a lot of personality.

It is reported that this Nike PG-2 PlayStation Colorway will be officially released on February 10.

LED light source uniforms to ensure the safety of traffic police

On the road full of traffic, the traffic police and officers on duty are in a high degree of danger. In order to ensure the safety of the traffic police, the Kolkata police in India have recently changed their uniforms, using uniforms equipped with outdoor transparent led screen light sources to allow driving at night or during rain and fog. It is easier to notice people directing traffic in the road.

A senior official of the traffic police in Kolkata, India, said that the uniforms equipped with LEDs can keep traffic police safe during the dark hours and reduce the risk of traffic accidents. These devices have been launched locally a year ago, and can ensure the safety of on-duty personnel during periods of fog or smog.

The designer installed a ring light consisting of red LEDs and blue LEDs on the shoulder straps. At present, the Indian military has 1,000 pieces. In order to enhance the safety of traffic police, 3,000 pieces will be distributed to traffic team personnel in the future. And because the LED lights will continue to flash, the police can be found as far as 500 meters away, which can remind the driver to control the speed while protecting the police.

Previously, an Indian soldier lost his legs in a car accident with a bus while on duty at night. This incident made the police pay attention to the safety of the officers on duty again. A sergeant said the safety of traffic police and night duty personnel was always a concern. The gear makes them feel safer, especially during the winter months, when the more prominent white uniforms go unnoticed due to the dark blue coats.

Whether it is for safety or aesthetics, LED uniforms can attract the attention of others. In 2016, the British easyJet Airlines also added LED lights to the uniforms of flight attendants, which can be used as billboards and display flights, destinations and other information. Data, in an emergency, can also be used as a human figure lighting.

The uniforms of the company’s ground staff and maintenance personnel are equipped with more LED light sources, and engineers can participate in inspection operations without flashlights. The uniforms are also equipped with air quality measuring devices, barometers and cameras, which can simultaneously transmit images For others, airlines can respond more quickly when faced with a situation

LED mask that glows with music

A few days ago, the start-up company Outline Montréal has developed a series of LED masks, which have many cool functions, the most impressive of which is its hearing ability. When ambient sounds are detected (such as loud electronic music), the color, brightness and strobe mode of the mask will change accordingly.

The glowing power of these LED masks is achieved through the cooperation of phosphor inks and regulators. Phosphor ink is a material with extremely low energy consumption, no heat generation and brilliant light effect. It is also the material chosen by many watches to light up the dial.

In use, the modulator transforms the sound waves into different lighting effects. This regulator is driven by a lithium battery, but the weight and volume are very small, and it will not cause too much burden to wear.

LED lights can also be embedded in the road as a zebra crossing

A new LED light traffic system embedded in the road has been put into trial in London, which can detect pedestrians and other vehicles, and change road lights and pipeline signs in real time according to road conditions to alert drivers of possible dangers. Especially when pedestrians or bicycles appear in the driver’s blind spot, the road surface will display a red light warning.

The new pavement embedded with LED lights was jointly developed by British company Umbrellium and car insurer Direct Line. In addition to the embedded LED road surface, this system also includes high-definition cameras to capture pedestrian and vehicle information, and the auxiliary system makes real-time feedback.

Zebra crossing and road safety have always been an important and complex part of the public transportation system, but from the rudiment of zebra crossing design in the 1940s to today’s highly developed traffic, the way people cross the road has not changed much. The increase in traffic accidents makes perfecting the zebra crossing and pedestrian traffic system a necessary consideration in the design of future smart cities.

Singapore team develops ultra-thin LEDs to help future communication technology

Scientists at the National University of Singapore have developed an energy-saving ultra-thin light-emitting diode (Llight Emitting Diode, LED), which is expected to be applied to the next generation of communication technology.

For information processing technology, it is very important to completely convert electrical signals (Electrical) into optical signals (Optical Signals). If a large amount of information is to be transmitted, it is necessary to integrate energy-saving and high-speed LEDs on the chip.

Graphene-like with a two-dimensional structure has only the thickness of carbon atoms, has clear light-emitting properties and can be placed on microchips, and has become a very popular semiconductor material in recent years. At present, research teams have used graphene-like materials to produce LEDs. However, only part of the current is converted into light through the electro-optic effect, and most of it is converted into heat energy dissipation. It is still a big challenge to achieve high efficiency of LEDs.

Goki Eda, a professor of the Department of Physics and Chemistry at the National University of Singapore, led a research team to successfully develop a high-efficiency ultra-thin LED, which contains only a few layers of carbon atoms, lcd display screen which can effectively reduce the energy lost by the LED in the electro-optic effect. The research team found that by preventing the leakage of current from the Emissive Layer (EML) to the metal electrodes (Metal Electrodes), the energy loss can be significantly reduced.

Studies have shown that an insulating layer a few nanometers thick can suppress current leakage without adding additional resistance. By using an extremely thin insulator, the team drastically reduced the current required to trigger the LED’s light, which is 10,000 times lower than that of a two-dimensional semiconductor LED.

Prof. Eda said, “Since our design ensures that the least amount of power is wasted, the device can operate at extremely low currents. This technology will have a great impact on future communication technologies.”
