The sample and hold circuit samples and holds the video input signals C1 through C3 selected by the multiplexer circuit
The sampled video signals are written to the LCD panel by output currents I
While INH = H, do not stop shift clocks CLI1 through CLI3.
Therefore, performing V
The output operation of this IC is controlled by INH signals.
