(4) Backlight lifetime means luminance value larger than half of the original after 20000 hours’ continuous working. (5) Input current of Pin 19 might change because the voltage of PIN19 will affect the efficiency of backlight driving circuit, but current for LEDs will keep constant within the range of input voltage. 3.2.2 Backlight Control Circuit For LCM（3x5=15 pcs LED） BL DRIVING CIRCUIT BLA (Input 5V Typ.)
