We haven’t talked about Analogix in a few years, and we certainly haven’t talked about TCON announcements much at all. At CES 2020 Analogix announced the new ANX2187 TCON chip with little fanfare, but it could drastically change the way PC displays are manufactured and how end products end up in terms of their colour accuracy.

Analogix has been a leader in delivering TCON solutions to the PC and laptop market for many years, and the market has been relatively speaking quite boring when it comes to new developments. Analogix wants to modernise the display panel experience for monitors and laptops with the introduction of the new ANX2186 which promises to bring 3D Colour Gamut rotation to the PC market.

Display makers usually have a quite hard time in terms of producing accurate display panels using the “traditional” manufacturing methods. In the old way of doing things, a panel’s colour accuracy is largely dependent upon its manufacturing and if it comes out matching the target specifications, with it being very hard for display vendors to individually adjust the display controller firmware on each panel in order to achieve better calibrations and accuracy.

The ANX2186 is a TCON that features gamut manipulation in the optical domain – in essence it’s a calibration engine that sits at the TCON level between the display input and the DDIC and is able to transparently manipulate the gamut in its 3D space. This technology isn’t inherently new, one area it’s been present for years has been in the mobile space (Samsung’s mDNIe was first as far as I know) as well as in TVs by various TV SoC vendors.
