3D Decoder based on LCD controller for Sharp™ dual-view digital panel

Product Status: Mass Production

OVERVIEW

The TW8810 is a highly integrated LCD TFT flat panel controller for Sharp™ dual-view LCD panel primarily targeting front console and rear-seat automotive infotainment applications. The TW8810 integrates a high quality NTSC/PAL/SECAM 3D video decoder and a 2D de-interlacer with low angle compensation. In addition, built-in dual-view mixer enables direct support for Sharp™ dual-view panel.
