FIG. 8 Measure Point for Luminance
The gray to gray response time is defined as the following figure and shall be measured by switching the
input signal for “Gray To Gray”.
- Gray step : 5 step
- TGTG_AVR is the total average time at rising time and falling time for “Gray To Gray”.
- In case of the difference in measured values due to the difference of measuring device or
program was found, correlated value will be used after discussions between both parties.
