Domestic screen breakthrough! Visionox launches world premiere mid-size 20-640Hz + wideband LTPS screen technology

According to news from this site on January 31, Visionox today announced the world’s first medium-sized broadband LTPS technology. This technology supports medium-sized AMOLED screens in the 20Hz-640Hz ultra-large range of broadband driving, bringing Better power consumption benefits.

640Hz refresh rate

Through the unique design of the driver circuit and supporting GIP circuit, Weixin Novo's mid-size wideband LTPS technology achieves a refresh rate of up to 640 Hz and a flicker value of -80dB (note on this site: the flicker of light).

Visionox said that this technology not only significantly increases the AMOLED screen refresh rate from 240Hz in May 2023 to 640Hz, but also breaks through the current highest refresh rate of various display technologies.

IC power consumption reduced by 21.5%

Due to the larger display area of ​​the medium-sized screen, human eyes are more sensitive to flicker in low-brush and low-brightness scenarios . Based on Visionox's LTPS backplane technology, medium-sized AMOLED screens can still maintain flicker-free display effects in 20Hz low-brush, low-grayscale, and low-brightness scenarios, and IC power consumption can be reduced by 21.5% (Visionox Experiments room calculation data).

AMOLED mid-sizeEconomic low-power solution

As AMOLED becomes mainstream in small-size applications, AMOLED becomes more popular in mid- and large-size applications Applications on the Internet have become a new “hot spot” for industry competition. Battery life is one of the most important indicators for medium-sized applications.

Based on this, Visionox has developed medium-sized broadband LTPS technology based on small-sized and low-power solutions, which is claimed to have low power consumption, high refresh rate, and wide-band drive. At the same time, there is no need to modify or upgrade the existing production line, and the production capacity of the production line is not sacrificed. To date, Visionox has applied for 269 key patents around broadband LTPS technology.
