Description
The CXA1819Q is an RGB driver designed for
LCD panel LCX007. It supports a line alternative
RGB drive system. In addition, three-panel
projectors can be supported by using three
CXA1819Q ICs.
Features
Built-in RGB signal phase matching sample-and-
hold circuit
Effective frequency response (horizontal resolution
of 600 TV lines achieved in combination with the
LCX007AL)
Built-in
control circuit
Built-in side black generation circuit for 4:3/16:9
