Measuring Conditions: 

- Environment: Dark room 

- Temperature: Ta=25 **°** C 

- Operating voltage adjusted for optimum contrast at the center of the display 

- Values measured at the center point of the LCD panel after more than 5 minutes of backlight operation 

**Figure 3 - Measurement Setup** 

2. The luminance uniformity is calculated using the following formula: 

**==> picture [109 x 20] intentionally omitted <==**

Bp (Max.) = Maximum brightness in 9 measured spots Bp (Min.) = Minimum brightness in 9 measured spots

5. Definition of response time. (Test equipment: DMS501) 

The output signals of the photo detector are measured when the input signal changes from “black” to “white” (falling time) and from “white” to “black” (rising time). Response time is defined as the time interval between 10% and 90% of the signal amplitude. Refer to the figure below for illustration.
