Signal
Description
P [0:23]
Flat panel data output for 18/24 bit TFT flat panels. Refer to table below for
configurations for various panel types. The flat panel data and control outputs are
all on-board controlled for secure power-on/off sequencing
SHFCLK
Shift Clock. Pixel clock for flat panel data
LP
Flat panel equivalent of HSYNC (horizontal synchronization)
FLM
Flat panel equivalent of VSYNC (vertical synchronization)
M
Multipurpose signal, function depends on panel type. May be used as AC drive
control signal or as BLANK# or Display Enable signal
ENBKL
Enable backlight signal. This signal is controlled as a part of the panel power
sequencing
ENVEE
Enable VEE. Signal to control the panel power-on/off sequencing. A high level may
turn on the VEE (LCD bias voltage) supply to the panel
