Analogix cuts power for DisplayPort timing control

Analogix Semiconductor has launched the ANX2403 a low-power Full-HD embedded DisplayPort 1.4 timing controller TCON) with panel self-refresh support.

In addition to panel self-refresh, the timing controller provides support for VESA DisplayHDR 400 together with in-cell finger and active-stylus touch for notebook PCs with graphics display resolution up to 1920×1280.

Together with the use of 28nm process technology, the design of the ANX2403 reduces the Full HD 60Hz power consumption to 60mW. It marks a 35 per cent reduction over the 40nm technology and a reduction of more than 50 per cent reduction over devices based on 55nm process technology, says the company. Analogix claims the ANX2403 is the lowest-power timing controller of its kind. The ANX2403 supports Intel low refresh rate and PSR2 for further power reductions.

“The ANX2403 brings together our capabilities in low-power processes, in-cell touch, and high-dynamic-range technology, offering the lowest power consumption to date, better image performance, and thinner panels with reduced bezels at a lower cost to display panel manufacturers,” said Michael Ching, vice- president of marketing for Analogix.

In terms of TCON functions, the ANX2403 supports colour depths up to 24bit, with 30bit for HDR support, and a 10bit Gamma correction table for each colour. For reliability and manufacturability, the device has programmable failsafe mode control and supports a configurable BIST pattern. To reduce motion blur in high-performance mode, the TCON supports LCD overdrive.

The ANX2403 provides Intel HDR400 support, meeting ST.2084 and BT.2020 standards. Additionally, the device can perform BT.2020 to sRGB colour-space mapping. Analogix says the ANX2403 has passed HDR400 testing at Allion.

Samples are available now and will ship in mass production in Q4 2018.
