Note 1: It shall be applied to pixel data signal, clock signal and control Pin.

Note 2: The maximum rating is defined as above based on the chamber temperature, which might be

different from ambient temperature after assembling the panel into the application. Moreover, some temperature-related phenomenon as below needed to be noticed:

- Background color, contrast and response time would be different in temperatures other than

C

- Operating under high temperature will shorten LED lifetime.

6. OPTICAL CHARACTERISTICS

The optical characteristics are measured based on the conditions as below:

- Supplying the signals and voltages defined in the section of electrical characteristics.

- The backlight unit needs to be turned on for 30 minutes.

$

- The ambient temperature is 25

- In the dark room around 500~1000 lx, the equipment has been set for the measurements as shown in Fig 6.1.

Note 4: The definition of response time is shown in Fig. 6.3. The rising time is the period from 90%

brightness to 10% brightness when the data is from white to black. Oppositely, Falling time is the period from 10% brightness rising to 90% brightness.

The viewing direction of this display is 12 o’clock, which means that a photograph with gray

scale would not be reversed in color and the brightness change would be less from this direction. However, the best contrast peak would be located at 6 o’clock.
