5. Electrical Characteristics 5.1 DC Characteristics for Panel Driving Table 5.2.1 LED Backlight Characteristics Note1: I is defined for each channel. F Note2: Optical performance should be evaluated at Ta=25°C only. Note3: If LED is driven by high current, high ambient temperature & humidity condition,The life time of LED will be reduced. Note4: Operating life means brightness goes down to 50% of initial brightness. Typical operating life time is estimated data.

Note2: The low level of these signals and analog powers are GND level. Note3: All of the power and signals should be kept at GND level before power on. If there are residual voltages on them, the LCD might not work properly. Note4: The power on/off sequence is the first version. It will be updated when the design is fixed. Note5: BL is the voltage applied to backlight. Keep...
