Visionox releases China's first 1Hz low-power AMOLED display

[Summary description] On February 22, Visionox released China's first 1Hz low-power AMOLED display, which can achieve a wide range of dynamic refresh rates from 1 to 120Hz through Hybrid-TFT technology. At the same time, mobile phones equipped with Visionox's 1Hz low-power AMOLED display will also be released soon.

Hybrid-TFT technology is favored by high-end flagship mobile phones because of its significant reduction in power consumption - it can automatically reduce the screen refresh rate to 1Hz in low refresh rate application scenarios such as screen-off display and reading, thereby reducing power consumption; When the user switches to high refresh rate application scenarios such as video and games

, the display can support a high refresh rate of 120Hz, making the display smoother without smearing.

China's first, largest production capacity, fastest mass production

The Hybrid-TFT low-power consumption technology was mass-produced by the Visionox (Hefei) G6 full-flex AMOLED production line, China's first "full-flex high-definition". The production line is positioned as "future-oriented high-end display technology". Visionox has successfully predicted the future development of AMOLED display technology in the planning and design stage.

In the direction of production line construction, it took the lead in laying out Hybrid-TFT low-power technology and its production capacity, and finally achieved the fastest Hybrid-TFT mass production speed and the largest Hybrid-TFT production capacity in China.

More complete TFT overall solution

The first mass production of the 1Hz low-power technology benefited from the "3" core areas laid out in the Visionox "2345" development framework - "optics and materials", "semiconductor devices" and "system integration", Among them, the "semiconductor device" refers to a large number of innovations made by Visionox for TFT and other technical fields.

and mass production application development.

Regarding the TFT-assisted low-power consumption solution, not only the above-mentioned Hybrid-TFT 1Hz solution is included, but Visionox has also pioneered the "30Hz low-frequency LTPS technology" in the world, which can be directly realized by using the original LTPS-TFT production line. The upgrade provides assistance for reducing the power consumption of mobile phones, which is both economical and energy-saving.

At the same time, Visionox's TFT innovative technology has also been further applied in the Micro-LED industry. Among them, the "glass-based double-sided LTPS-TFT backplane process" realizes side routing, so that the frame can reach the micron level (<100μm), and the real Can do seamless splicing.

Previously, Visionox launched a 144Hz AMOLED display with the highest refresh rate in the world in 2020, and it will reach 165Hz again in 2021 and has maintained its global innovation leadership so far, making it unique in the field of TFT technology.

Clearer, tripod-shaped pixel arrangement

The 1Hz low-power AMOLED display released this time adopts Visionox's "tripod-shaped pixel arrangement", which has the world's highest visually equivalent pixel density, making the display more uniform, sharper and more delicate. Visionox has innovative design and delivery capabilities for pixel arrangement, and can provide

The overall solution of pixel arrangement, TFT and SPR algorithm is quickly introduced into mass production. Previously, the tripod-shaped pixel arrangement has been successfully mass-produced in a variety of full-screen mobile phones and foldable mobile phones.

Taking China's first 1Hz low-power AMOLED display as the beginning of the new flagship, Visionox will rely on its innovation advantages, insist on leading China's emerging display industry with technological innovation, and promote my country's promotion of high-level technological self-reliance.
