= 25 ± 5°C, V
Remarks 1. The contrast ratio is calculated by using the following formula.
Parameter
Horizontal
Vertical
2. Definitions of viewing angle are as follows.
3. The luminance is measured after 20 minutes from the module works, with all pixels in white.
CC
The Luminance is measured in darkroom.
Typical value is measured after luminance saturation.
Contrast ratio (CR) =
= 3.3 V , MVA = V
