EK7603
402/480- Output TFT LCD Analog Source Driver
1. GENERAL DESCRIPTION
The EK7603 is an analog, fully color, source driver for TFT LCD panels designed for camera, TV etc.
Analog R, G and B signal are applied directly on the chip. For each of the 402/480 outputs, the voltage
is sampled and buffered to the panel. With a double sample and hold circuit a new voltage can be
sample whereas the previous sample voltage is applied to the panel.
According to different modes, the 3 input voltages (VA, VB, VC) can be applied on different output to
support various pixel array types.
The 3 input voltages (VA, VB, VC) can be sampled simultaneously or sequentially to have a better
flexibility with the input voltage. Using enable signal (STHx), several chips can be cascaded for large
panel.
