TW8823
Advanced LCD controller with on-chip MCU
and 65K color 16-bit OSD support
The TW8823 is a highly integrated advanced LCD controller designed for the automotive infotainment market, targeting center console and rear
seat entertainment applications. Features such as an embedded MCU, LED/CCFL backlight controllers, a 4-wire touch screen controller, analog
and digital TCON, and a multi-window 16-bit (65K color) bit-map OSD are designed to reduce the system’s overall BOM cost. The TW8823 has
multiple analog and digital inputs to support a wide array of video and graphic sources, including navigation modules, back-up cameras,
DVD/multimedia modules, PCs, etc. The TW8823 can support a wide variety of both digital & analog LCD panels with resolutions up to WXGA,
and also has an integrated single channel LVDS interface to directly drive LVDS based LCD panels.
