Definition of viewing angle Note 2: Test equipment setup: After stabilizing and leaving the panel alone at a driven temperature for 10 minutes, the measurement should be executed. Measurement should be executed in a stable, windless, and dark room. Optical specifications are measured by Topcon BM-7orBM-5 luminance meter 1.0° field of view at a distance of 50cm and normal direction. Page 6 of 9 Fig. 7.2. Optical measurement system setup ## Note 3: Definition of Response time: The response time is defined as the LCD optical switching time interval between “White” state and “Black” state. Rise time, Tr, is the time between photo detector output intensity changed from 90%to 10%. And fall time, Tf, is the time between photo detector output intensity changed from 10%to 90% **==> picture [389 x 81] intentionally omitted <==** **----- Start of picture text -----**

## Note 4: Definition of contrast ratio: The contrast ratio is defined as the following expression. Luminance measured when LCD on the "White" state Contrast ratio (CR) = Luminance measured when LCD on the "Black" state Page 7 of 9 ## Note 5: Definition of Luminance Uniformity Active area is divided into 9 measuring areas (reference the picture in below). Every measuring point is placed at the center of each measuring area. Luminance Uniformity (U) = Lmin/Lmax x100% L = Active area length W = Active area width Fig7.3. Definition of uniformity Note 6: Definition of color chromaticity (CIE 1931) Color coordinates measured at the center point of LCD Note 7: Measured at the center area of the panel when all the input terminals of LCD panel are electrically opened.
