 Luminance uniformity measure specification 
1)  Impress 100 % (255Gray Level) full white pattern at the same peak brightness measurement. 
2)    Measure brightness L0~L8 in each 9 points P0~P8 
  - Luminance uniformity(%) = Minimum(L1, L2, L3, …, L8) / Maximum(L1, L2, L3, …, L8) * 100 
      - Average Luminance = Sum of Luminance(L1, L2, L3, …, L8) / 9 
3)    Measure average brightness in IOP LED 17 points.

1) Measuring instrument : PR-880.   
2) Measuring Mode : Picture mode Vivid Default 
3) Response time is the time required for the display to transit from G(N) to G(M) (Rise Time, TrR) 
        and from G(M) to G(N) (Decay Time, TrD). For additional information see the FIG. 3. (N<M) 
        ※  G to G Spec stands for average value of all measured points. 
4)    Response time is defined as the following figure and shall be measured by switching the input signal for “Gray(N)” and “Gray(M)”
