Note (1) All of the specifications are guaranteed under normal conditions. Normal conditions are defined as follow: Temperature: 25ºC, Humidity: 55± 10%RH.
Note (2) All of the absolute maximum ratings specified in the table, if exceeded, may cause faulty operation or unrecoverable damage .It is recommended to follow the typical value.
Note (3) The specified VCC current and power consumption are measured under the VCC = (3.3) V, FV= (60) Hz condition and Black pattern.
Note (4) The figures below is the measuring condition of VCC. Rush current can be measured when TRUSH is 0.5 ms.
Note (5) The power consumption of LED Driver are under the VLED = (12) V, Dimming of Max luminance.
Note (6) Although acceptable range as defined, the dimming ratio is not effective at all conditions. The PWM frequency should be fixed and stable for more consistent luminance control at any specific level desired.
Note (7) The operation of LED Driver below minimum dimming ratio may cause flickering or reliability issue.
Note (8) The life time is determined as the sum of the lighting time till the luminance of LCD at the typical LED current reducing to 50% of the minimum value under normal operating condition.
