On November 16th, TCL Huaxing held THE DTC 2021 Global Display Ecology Conference, and finally launched five new products: The world's first 65-inch 8K (7680x4320) inkjet PRINTED OLED TV, 14-inch Yunson inkjet printed OLED display, the world's first 8-inch non-polarized minimal radius 360° folding screen, the world's highest area 49-inch R800 5120 partition MLED display module, the world's first 125-inch glass-based transparent direct DISPLAY MLED product.

According to the introduction, 49 inch Mini LED curved display integrates 50,000 Mini LED light beads, with 5120 high partition to achieve ultra-accurate light control, peak brightness of 1800nits, contrast of 1,000,000/1, display curvature of R800, combined with TCL Huexing 0 OD no shadow design technology, Immersive surround visual experience with ultra-high definition display, ultra-high contrast, ultra-high refresh rate at 240Hz and ultra-wide viewing Angle.

125-inch transparent Mini LED direct display is based on glass-based active drive technology, with penetration rate ≥70%, average brightness of 1000Nits and peak brightness of 2000Nits. Compared with the traditional PCB grille transparent screen, this product has a higher penetration rate, smaller pixel area, can bring a better sense of transparency and more delicate display screen, suitable for business office, outdoor advertising, cinema and other commercial application scenarios.

According to introduction, the display adopts TCL Huaxing's high-precision glass splicing technology, with 25-inch monotone as the smallest splicing unit, through free splicing to achieve the transparent form of large-size splicing, and can achieve 2 x N unlimited, seamless splicing, supporting the customization requirements of different environments. TCL Huaxing said transparent display products also have unlimited development potential in shopping malls, museums and other application scenarios.

In addition, TCL Huaxing displayed 75-inch P0.6 oxide AM DIRECT DISPLAY MLED TVS in the exhibition area. Leard supplied the Micro LED flip chip and was responsible for the core of solid (bulk transfer) manufacturing and Compression Molding. It can be seen that TCL Huaxing and Leard are steadily advancing towards the common development goal. Through the deep integration of the upstream and downstream industrial chain, they are gradually tackling the technical problems of display and accelerating the landing of products.

In terms of Micro LED, TCL Huaxing exhibited a 1.37" AM Micro LED watch, a 7.1-inch flexible Micro LED display and a 6.24-inch highlight Micro LED display.

1.37" AM Micro LED watch

Among them, the 1.37" AM Micro LED watch has a PPI of 353, which is said to be the highest PPI Micro LED wearable product in the industry at present. The display effect is exquisite and delicate. At the same time, the product is driven by TFT-LTPS technology, the peak brightness can reach 2000Nits, the color gamut is 112 NTSC%, the color reduction degree is high, the visual experience is excellent. In addition, it is also the industry's first integrated in-cell touch technology Micro LED products, MOD stacking can achieve ultra-thin design, more convenient to carry.

At the meeting, TCL Huaxing mentioned that the Micro LED production process is still facing three major difficulties: massive transfer, metal bonding and LED chip efficiency. The joint laboratory of TCL Huaxing and SAN 'an Optoelectronics is relying on TCL's backplane technology, drive and compensation technology, module technology and splicing technology. And SAN 'an photoelectric high efficiency chip technology, massive transfer technology, bonding technology and defect repair technology, through the complementary advantages of technology and resources, tackle Micro LED production problems, promote the commercialization of large size Micro LED.

In fact, TCL, huaxing has relatively large technical ecosystem, on the combination strategy, more than leah, and three optoelectronic, TCL huaxing also with millet, south China institute of technology, set up a joint laboratory, at the same time, Beijing institute of technology and material research institute of Chinese Academy of Sciences higher scientific research institutions to maintain close cooperation, focusing on key materials and technology, All-round development of new display technology, help the localization of core materials and technologies.
