The TW8836 is a highly integrated LCD video processor that
incorporates many of the features required to create a
multipurpose LCD display system into a single package. This
includes a high quality 2D comb NTSC/PAL/SECAM video
decoder, triple high speed RGB ADCs, an LVDS and TTL digital
input interface, high quality scaler and deinterlacer, as well as a
versatile OSD, high performance MCU and LVDS or TTL output
panel interface. The TW8836 can support input resolutions up
to 1080p and can drive LCD panels at resolutions up to
1366x768. The TW8836’s video processing capability includes
arbitrary H/V scaling, panoramic scaling, image mirroring,
image adjustment and enhancement, black and white stretch,
etc. The feature set and versatility of this device makes it an
ideal solution for in-car LCD display applications, as well as
portable display applications such as Pico Projectors.
