Signal
Description
V
H
Power supply voltage for display functions. 12 VDC nominal.
V/Q
Format selection: in AMLCD timing modes, selects between VGA mode
(high) and QVGA mode. In VGA mode, the upper left quadrant of data will
be displayed. Internally pulled low.
DE
Data Enable: in AMLCD non-fixed timing modes, the rising edge identifies
the data for the first pixel of each row and must stay high until the data
for the last pixel of each row is clocked. DE is also used to determine the
video timing mode. Internally pulled high to 3.3 V.
LUMA
Analog Luminance Control: used to reduce the display luminance by
reducing the voltage applied to the display phosphor. If left open, defaults
to the luminance set by LUM0 and LUM1.
LUM0, LUM1 Digital Luminance Controls: used to reduce the luminance of the display
by reducing the frequency at which the display is scanned.
VS
Vertical Sync: identifies the start of each frame (entire screen) of data.
Internally pulled low.
HS
Horizontal Sync: identifies the start of each horizontal row of data.
VCLK
Video Clock: the falling edge latches the video data (R0, R1, G0, and G1).
R0
Video data: Least significant bit for red sub-pixel.
R1
Video data: Most significant bit for red sub-pixel.
G0
Video data: Least significant bit for green sub-pixel.
G1
Video data: Most significant bit for green sub-pixel.
SHUTDOWN Display Shutdown: when high, will disable the display, thus rendering the
display black and minimizing power. All display data will be stored but no
new data accepted when SHUTDOWN is high. Internally pulled low.
GND
Signal return for power and logic.
