4.4 POWER SUPPLY VOLTAGE SEQUENCE
4.4.1 LCD panel signal processing board
VCC
Note1
3.0V or 4.75V
0V
ON
10μs≤Tr < 30ms
Display signals
Function signal
Note2
0V
0ms < t < 35ms
VALID period
NL6448BC33-70D
OFF ON
Toff > 50ms
0ms < t < 35ms
Note1: If there is a voltage variation (voltage drop) at the rising edge of VCC below 3.0V in "VCC =
3.3V" or 4.75V in "VCC = 5.0V", there is a possibility that a product does not work due to a
protection circuit.
Note2: Display signals (CLK, Hsync, Vsync, DE, DATA (R0 to R5, G0 to G5, B0 to B5)) and
function signal (DPS) must be set to Low or High-impedance, except the VALID period (See
above sequence diagram), in order to avoid the circuitry damage.
If some of display and function signals of this product are cut while this product is working,
even if the signal input to it once again, it might not work normally. If a customer stops the
display and function signals, VCC also must be shut down.
4.4.2 LED Driver board (Option)
Display signals
Function signal
Note1
Note2
VALID period
LED backlight: ON
Note1: These are the display and function signals for LCD panel signal processing board.
Note2: The backlight should be turned on within the valid period of display and function signals, in
order to avoid unstable data display.
