Notes 1.
The contrast ratio is calculated by using the following formula.
Luminance with all pixels in white
Contrast ratio (CR) =Luminance with all pixels in black
The Luminance is measured in darkroom.
2.
The luminance is measured after 20 minutes from the module works, with all pixels in white. Typical
value is measured after luminance saturation.
