Contrast Ratio (CR) is defined mathematically as:
7.
Surface luminance is luminance value at point 5 across the LCD surface 50cm from the surface
with all pixels displaying white. From more information see FIG 2. LWH=Lon5 where Lon5 is
the luminance with all pixels displaying white at center 5 location.
8.
The variation in surface luminance, _WHITE is defined (center of Screen) as:
δ
HITE(9P)= Minimum(Lon1, Lon2,…,Lon9)/ Maximum(Lon1, Lon2,…Lon9)
9.
Response time Tr is the average time required for display transition by switching the input
signal for five luminance ratio (0%,25%,50%,75%,100% brightness matrix) and is based on
Fv=60Hz to optimize.
The response time is defined as the following figure and shall be measured by switching the input signal for
“any level of grey(bright) “ and “any level of gray(dark)”.
Any level of gray (Bright) Any level of gray (Dark) Any level of gray (Bright)
