TW8835
LCD Video Processor with Built-In Decoder, MCU, OSD, TCON and Analog RGB
Input Support
The
TW8835
incorporates many of the features required to
create multipurpose in-car LCD display system in a single
package. It integrates a high quality 2D comb
NTSC/PAL/SECAM video decoder, triple high speed RGB ADCs,
high quality scaler, versatile OSD and high performance MCU.
Its image video processing capability includes arbitrary
scaling, panoramic scaling, image mirroring, image
adjustment and enhancement, black and white stretch, etc. On
the input side, it supports a rich combination of CVBS, S-video,
component video, analog RGB as well as digital YCbCr/RGB
inputs. On the output side, it supports a variety of digital panel
types with its built-in timing controller. The integration of
additional touch screen controller, LED driver controller, PWM
and MCU makes this a versatile solution for many portable
applications.
