LED array electrical characteristics

Note (1) The LED can work normally if the PWM dimming ratio range is from 0% to 100% and the operation current

is 60mA.

Note (2) PLED = (ILED ×4) × VLED , LED matrix is 15S4P.The lightbar used by backlight unit.

Note (3) The lifetime of LED is defined as the time when it continues to operate under the conditions at Ta = 25 ±2 ℃

and I =

60 mA(Per EA) until the brightness becomes ≤50% of its original value.

Note(4): Pulse Width ≦10 msec and Duty ≦ 1/10

Note(5)：Voltage &Temperature curve
