Recently, the Universal Display Expo (UDE2020) and iLife2020, guided by the Department of Electronic Information of the Ministry of Industry and Information Technology, the Shanghai Municipal Commission of Economy and Information Technology, and the China Electronic Video Industry Association, was held at the Shanghai New International Expo Center.

This is a display event. In this event, you can see all kinds of display technologies, as well as various display methods and display applications. Similarly, you can also see smart TVs and mobile phones that are closest to our lives, full of visual impact and extremely comfortable scenes.

Innovative quantum dot and OLED display technology
In fact, these two display technologies will not be repeated here, because the dispute between quantum dots and OLED as the next generation technology has entered a fierce battle. After years of development, quantum dots and OLED are very mature technically and also in terms of volume. Form a certain scale, they are all powerful competitors for the next generation of display technology.

The focus here is to bring you the Mini LED, Micro LED, laser and flexible AMOLED that are very popular recently and are highly popular on UDE2020.

Mini-LED display technology
Mini-LED is an LED technology with a new backlight design that can significantly improve the thickness of the backlight display, making it lighter and thinner, and provides the same advantages as OLED screens, including good color gamut, high contrast and dynamic range, and With the HDR capability of partially brightening and dimming, there is also news that Apple's MacBook and iPad will skip OLED and directly enter the mini-LED era.

TCL Mini-LED BLU TV 75" 8K Star Screen
The most prominent representative is TCL. At this year’s CES2020, TCL released the next generation of Mini-LED display technology, and with Quantum Contrast technology, TCL has established a TV image New quality standard. At UDE2020, TCL brought the world's first a-Si TFT Mini-LED BLU TV 75" 8K star screen. This screen has 5184 subarea backlights, which can achieve high-brightness and pure black dark details, and the picture can be clearly displayed under backlight conditions.

In addition, the contrast ratio of the product is as high as 1,000,000:1, which is twice that of dual screens. Mini-LED is transferred from the traditional PCB backplane (printed circuit board) to a lower cost glass substrate, reducing the overall cost. The glass substrate Mini-LED screen can provide thousands to tens of thousands of display zones for dynamic dimming. Compared with the hundreds of zones of the same size PCB backplane Mini-LED screen, the display effect is better, and it is more energy-efficient and efficient.

Mini LED is a strong competitor of next-generation display technology. As more and more brands launch Mini LED products, its competitiveness will increase greatly. In addition, Micro LED, which is inextricably related to Mini LED, is also a competitor of next-generation display technology, and the popularity of UDE2020 is no less than Mini LED.

Nationstar Optoelectronics Mini-SMD backlight device
Nationstar mini backlight products can achieve the display effect of RGB three primary colors, and can cover 100% of the wide color gamut of BT2020, and the vividness of colors is comparable to OLED. The product has the characteristics of high brightness (>1000nit), combined with fine local dimming, can achieve ultra-high contrast (1000000:1), making the black deeper and brighter, which can fully meet the needs of professional design, photography, film and television post-production of the high-end consumer market.

Micro LED display technology
What is Micro LED technology? It is LED miniaturization and matrix technology, that is, the LED (light emitting diode) backlight is thinned, miniaturized, and arrayed, so that the LED unit can be smaller than 50 microns. Like OLED, each pixel can be individually addressed and separately luminous (self-luminous).

Its advantage is that it not only inherits the high efficiency, high brightness, high reliability, and fast response time of inorganic LEDs, but also has the characteristics of self-illumination without backlight, small size, light and thin, and can easily achieve energy-saving effects. Theoretically, MicroLED can provide perfect black (all micro LEDs can be turned off individually), best-in-class brightness, incredible HDR color gamut, without aging, and longer battery life than OLED panels.

At this UDE2020, many upstream panel manufacturers and terminal companies have launched Micro LED products to show Chinese power.

Tianma transparent Micro-LED
Tianma 7.56" transparent Micro-LED adopts AM LTPS backplane, and transfers the Micro-LED RGB chip to the glass TFT substrate through mass transfer technology. The brightness can reach 600nits and the color gamut is higher than 116% NTSC. Under the special panel design, the transmittance can reach 60%, the PPI is as high as 114, and the resolution is 720x480. In addition, Tianma also displayed a transparent 5.04" Micro-LED splicing screen, a very narrow frame. The display screen, through special panel circuit design, optimized packaging structure and technology, is committed to de-frame splicing large screens with extremely narrow frames.

Ledman Optoelectronics 8K Micro LED
Ledman Optoelectronics demonstrated a 324-inch 8K Micro LED high-definition display. This display is provided by HC Semitek with LED chips with a dot pitch of 0.9mm and uses a common cathode IC. It is 4.05m high and 7.2m wide, and consists of 144 27-inch boxes forming a 29.16 square meter display giant screen. It supports high dynamic HDR and can provide an immersive experience. The contrast ratio exceeds 10000:1, and the strong contrast between light and dark makes the display deep and three-dimensional. The 22bit gray scale is finely managed and the light and dark transition is natural. The product adopts the optical design of the panel surface to improve the light output efficiency of the chip, effectively manage the surface temperature, and the surface temperature is effectively reduced by 5℃.

Flexible AMOLED display technology
Flexible AMOLED display technology has actually been out for a long time, and it has been applied in many fields, especially the flexible display brings more possibilities for the entire creative display. For example, the folding screen mobile phones launched by Samsung, Huawei, Motorola.

Visionox flexible AMOLEDUDE2020 Universal Display Expo innovative display technologies

Visionox flexible AMOLED
Visionox flexible AMOLED 360° folding terminal, a screen that has mass production capability. It has an outer folding radius of 8mm and an inner folding radius of 2.85mm. It has passed 100,000 folding tests. A Visionox O-Flex surround screen solution was also exhibited at the scene. Its screen-to-body ratio is as high as 180.6%, which is a perfect arc on both sides formed by the 360° flexible AMOLED full module and surround fit.

UDE also shows the rise of "Chinese power" in the display technology industry. As more and more innovative display technologies are presented, we will see a more colorful horizon.
