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 C
- In the dark room around 500~1000 lx, the equipment has been set for the measurements as shown in
Note 1: The brightness is measured from the center point of the panel, P5 in Fig. 6.2, for the typical
Note 2: The brightness uniformity is calculated by the equation as below:
, which is based on the brightness values of the 9 points measured by BM-5 as shown in Fig. 6.2.
