Test and measurement conditions

1. All measurements shall not be started until the specimens attain to temperature stability.

After the completion of the described reliability test, the samples were left at room

temperature for 2 hrs prior to conducting the failure test at 23±5°C; 55±15% RH.

2. All-pixels-on is used as operation test pattern.

3. The degradation of Polarizer are ignored for High Temperature storage, High Temperature/

Humidity Storage, Temperature Cycle

Evaluation criteria

1. The function test is OK.

2. No observable defects.

3. Luminance: > 50% of initial value.

4. Current consumption: within ± 50% of initial value.

APPENDIX:

RESIDUE IMAGE

Because the pixels are lighted in different time, the luminance of active pixels

may reduce or differ from inactive pixels. Therefore, the residue image will occur.

To avoid the residue image, every pixel needs to be lighted up uniformly.
