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.
