2. FUNCTION DESCRIPTION
2.1 Multiplexer Circuit
crystal panel, and outputs the signals to the H
MP/1.5 pins.
This circuit selects RGB video signals input to the C
Vertical stripe array, single-/double-side delta array, or mosaic array can be selected by using the MP/TH and
2.1.1 Vertical stripe array mode (MP/TH = L, MP/1.5 = L)
mode is used to drive a panel of vertical stripe array. In this mode, the multiplexer circuit is in the through
status.
Relation between video signals C
Pixel arrangement of vertical stripe array and multiplexer operation
In this mode, the relation between video signals C
