The method of visual inspection is equal to the appearance standard. Evaluation and assessment made
two hours after return to room temperature (25 ± 5°C). The LCDs subjected to the test must not have
dew condensation.
The test pattern is gray scale and the operating voltage sweep from Vth to Vsat variable.
The non-uniformity and other appearance are checked in LCD.
Life time expectancy of LCD Panel is approximately 50,000 hours under the room environment. Defini
tion on the termination of life time is deterioration of contrast ratio by one fifth against
initial value.
There should be no change which might affect the practical display function when the display quality
test is conducted under normal operating condition.
* Place all the samples under room temperature & humidity for 24 hours after reliability stressing.
* Room environment means 25+/-10°C, 45+/-20%RH
* There should be no condensation during the test.
* One LCD module shall be used for one test item only and once.
* Contrast (or Brightness) ratio variation is within 50% of the initial value.
* No abnormal function
* No extreme decay on appearance
Display (LCD module) : Life time expectancy of LCD Panel is approximately 50,000
