Backlight Note3
Note1: Relations between GND (Signal ground) and FG (Frame ground) in the LCD module is as
follows.
GND-FG
Connected
Note2: GND and FG must be connected to customer equipment's ground, and it is recommended that
GND and FG are connected together in customer equipment.

VALID period
0.01ms < t < 50ms
* These signals should be measured at the terminal of 100Ω resistance.
Note1: In terms of voltage variation (voltage drop) while VCC rising edge is below 3.0V, a protection
circuit may work, and then this product may not work.
Note2: Display signals (D0+/-, D1+/-, D2+/-, D3+/-, CLK+/-) and function signals (MSL, DPS) must
be Low or High impedance, exclude the VALID period (See above sequence diagram), in
order to avoid that internal circuit 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. VCC should be cut when
the display and function signals are stopped.
Note3: The backlight should be turned on within the valid period of display and function signals, in
order to avoid unstable data display.

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.
