7-2. Backlight driving
[Note 1] The LED backlight is composed by 2 channels 5 from which 7 LED is connected with the series.
[Note 2] Calculated value for reference ( I
[Note 3] Above value is applicable when lamp (the long side of LCD module) is placed horizontally.

The backlight system is an edge-lighting type with white-LED.
The characteristics of LED are shown in the following table.
(It is usually required to measure under the following condition.
Timing diagrams of input signal are shown in Fig.2.
[Note] In case of lower frequency, the deterioration of display quality, flicker etc.,may be occurred.
The horizontal display position is determined by ENAB signal and the input data corresponding to the
rising edge of ENAB signal is displayed at the left end of the active area.

Life time is defined that it applied under this condition
In case of operating under higher temperature environment, the LED exhaustion is accelerated
the brightness becomes lower.
(Continuous turning on at Ta=25
・Brightness becomes 50% of the original value under standard condition.
