5. FUNCTIONAL DISCRIPTION
5.1 Multiplexer Circuit
panel, and outputs the signals to the H
MP/1.5 pins.
5.1.1 Vertical stripe array mode (MP/TH = L, MP/1.5 = L)
drive a panel of vertical stripe array. In this mode, the multiplexer circuit is in the through status.
Remark ( ) indicates the case of left shift.

This circuit selects RGB video signals input to the C1 to C3 pins according to the pixel array of the liquid crystal
Vertical stripe array, single-/double-side delta array, or mosaic array can be selected by using the MP/TH and
In this mode, the relation between video signals C1 to C3, and output pins is as shown below. This mode is used to
