3D Video Decoder Based LCD Controller with Built-in LVDS Panel Interface

Device is no longer available or supported, and production has been discontinued.

Product Status: EOL

OVERVIEW

TW8813 is a highly integrated and flexible LCD controller for the automotive infotainment market, including front console and rear seat entertainment applications. TW8813 integrates an 8-bit LVDS panel interface to support digital panels up to 720p resolution. TW8813 also embeds a built-in high quality 3D video decoder, 2D Scaler/De-interlacer, TCON, panel back-light controllers and bit-map OSD engine in a single package. TW8813 supports a variety of analog inputs and adds flexibility by supporting two Digital RGB input ports.
