4.4 POWER SUPPLY VOLTAGE SEQUENCE
4.4.1 Sequence for LCD panel signal processing board
VCC
Note1
3.0V or 4.75V
0V
Display and
function signals
Note2
ON
Tr < 30ms
0ms < t < 35ms
VALID period
NL6448BC33-54
OFF
Toff > 50ms
0ms < t < 35ms
Note1: In terms of voltage variation (voltage drop) while VCC rising edge is below 3.0V in
"VCC = 3.3V" or 4.75V in "VCC = 5.0V", a protection circuit may work, and then this
product may not work.
Note2: Display (CLK, Hsync, Vsync, DE, R0 to R5, G0 to G5, B0 to B5) and function (DPS)
signal must be Low or High-impedance, exclude the VALID period (See above sequence
diagram), in order to avoid that internal circuits is damaged.
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 customer
stops the display and function signals, they should be cut VCC.
4.4.2 Sequence for backlight inverter (Option)
Display and
function signals
Note1
Note2
VALID period
VDDB
Note1: These are the display and function signals for LCD panel signal processing board.
Note2: The backlight inverter voltage (VDDB) should be inputted within the valid period of
display and function signals, in order to avoid unstable data display.
