4.4 POWER SUPPLY VOLTAGE SEQUENCE
4.4.1 LCD panel signal processing board
VCC
Note1
0V
ON
3.0V
10μs ≤ Tr < 50ms
Display signals*
Function signals
Note2
0V
0ms < t < 35ms
VALID period
NL12880BC20-05D
OFF ON
0.3V
Toff ≥ 50ms
0ms < t < 35ms
* These signals should be measured at the terminal of 100Ω resistance.
Note1: If there is a voltage variation (voltage drop) at the rising edge of VCC below 3.0V, there is a
possibility that a product does not work due to a protection circuit.
Note2: Display signals (D0+/-, D1+/-, D2+/-, D3+/- and CLK+/-) and function signals (DPS, FRC
and MSL) 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
Display signals,
Function signals
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.
