2. Inspection condition

Viewing distance for cosmetic inspection is about 30cm with bare eyes, and under an

environment of 20~40W light intensity, all directions for inspecting the sample should be within

45°against perpendicular line. (Normal temperature 20∼25°C and normal humidity 60±15%RH).

 Driving voltage

The Vop value from which the most optimal contrast can be obtained near the specified Vop in the

specification (Within ±0.5V of the typical value at 25°C.).

3. Definition of inspection zone in LCD.

Zone A: character/Digit area

Zone B: viewing area except Zone A (ZoneA+ZoneB=minimum Viewing area)
