概要
説明
The TW8849 is a highly integrated LCD video processor that incorporates many of the features required to create a multipurpose LCD display system. These features include two LVDS Open LDI input interfaces, two separate high quality scaler and de-interlacer engines, as well as dual channel LVDS Open LDI output interfaces to drive up to 2 LCDs. The TW8849 can support input resolutions up to 1080p and can drive LCD panels at resolutions up to 1920 × 1080.
The TW8849’s video processing capability includes 10-bit per color image enhancement processing, arbitrary H/V scaling, panoramic scaling, image mirroring, image adjustment, black and white stretch, Automatic Contrast Adjustment, and smooth input switching. In addition, the TW8849 has image diagnostic capabilities to determine if the input video is corrupted or frozen. The feature set and versatility of this device makes it an ideal solution for all Automotive LCD display applications.
