(4) Backlight lifetime means luminance value larger than half of the original after 20000 hours’ continuous working. (5) Input current of Pin 21 might change because the voltage of PIN21 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(2x6=12 pcs LED) 2 2 :0 V B L D R IV IN G CIRCU IT P IN 22 is c onnec te d to P IN 2 (V S S ) in te rn a lly 2 1 :+ 3 V ~ 5 .5 V IN 3.2.3 LED Characteristics Curves(for single led) 1.Forward current VS.Ambient Temperature 25 20 15 10 -30 5 0 100 Ambient Temperature 25 050 80 45 30 3 2 15 20 0 5 10 Forward Voltage 25 2.Forward current VS Forward Voltage |
