Note 1: Refer to Fig.4- (a).
Note 2: The brightness of LCD panel could be changed by adjusting the AC component of
VCOM.
Note 3: STHL, STHR, OEH, L/R, CPH1~CPH3, STVR, STVL, OEV, CKV, U/D.
Note 4: Be sure to apply GND, VCC and VGL to the LCD first, and then apply VGH.

Note 6
Note 1: Ta = 25℃ .
Note 2: Ta = 0℃ .
Note 3: Ta = -30℃ .
Note 4: The lamp frequency should be selected as different as possible from display
horizontal synchronous signal to avoid interference.
Note 5: For starting the backlight unit, the output voltage of DC/AC’s transformer should be larger
than the maximum lamp starting voltage.
Note 6: The” Lamp life time” is defined as the module brightness decrease to 50% original
brightness at Ta=25℃ , IL=6mA.
