TFT Display Controller

TW8832, TW8832S

Applications

Description

The TW8832 incorporates many of the features

required to create multi-purpose 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, and images

enhancement functions which include Black and

White Stretch and etc. It also supports panoramic

scaling for conversion to wide screen display. On the

input side, it supports a rich combination of CVBS, S-

video, analog RGB as well as digital inputs. On the

output side, it supports variety of digital panel types

with its built-in timing controller.

− Analog Video Decoder

− NTSC (M, 4.34) and PAL (B, D, G, H, I, M, N, N

combination), PAL (60), SECAM with automatic format

detection

− Three 10-bit ADCs and analog clamping circuit

− Fully programmable static gain or automatic gain

− Programmable white peak control for the Y or CVBS

− Software selectable analog inputs

− High quality adaptive 2D comb filter for both NTSC

− PAL delay line for color phase error correction

− Image enhancement with 2D dynamic peaking and

− Digital sub-carrier PLL for accurate color decoding

− Digital horizontal PLL and Advanced synchronization

− Programmable hue, brightness, saturation, contrast

− High quality horizontal and vertical filtered down
