all pixels displaying white at center 5 location.
The variation in surface luminance, _WHITE is defined (center of Screen) as:
3.
δHITE(9P)= Minimum(Lon1, Lon2,...,Lon9)/ Maximum(Lon1, Lon2,...Lon9)
Response time Tr is the average time required for display transition by switching the input signal for five
4.
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)

5. Viewing angle is the angle at which the contrast ratio is greater than 10. The angles are
determined for the horizontal or x axis and the vertical or y axis with respect to the z axis which is
normal to the LCD surface. For more information see FIG3.
