The PD16602 is a TFT-LCD source driver with full color display capability. It is ideal for 1024 x 768 pixel (XGA) class high definition displays. The internal circuit consists of 12 channels (4 x 3) of analog input pins, 12 channels of 16-bit shift registers and 312 channels of sample & hold circuits (2 latch type). Analog display signals are sampled in 12 channels simultaneously by the sample & hold circuits and they are output in the next line. The output voltage of the sample & hold circuits is as great as 10.5 VP-P and maintains high accuracy with an output deviation of 20 mVMAX. Inputting analog display signals that been -processed in the previous stage signal processing circuit allows realization of a high definition 256-gray-scale-equivalent full color display without requiring line inversion.
