Professional, Creditable, Successful Note 1: Definition of optical measurement system. The optical characteristics should be measured in dark room. After 5 minutes operation, the optical properties are measured at the center point of LCD. Note 2: Definition of viewing angle range and measurement system. The viewing angle is measured at the center point of the LCD by BM-7A. Note 3: Definition of color temperature. When the radiation of the light source is exactly the same in the visible region and the absolute blackbody, the temperature of the blackbody is called the color temperature of the light...

Professional, Creditable, Successful Note 4: Definition of response time. The response time is defined as the LCD optical switching time interval between “White” state and “Black” state. Time ON (TON) is the time between photo detector output intensity changed from 90% to 10%. And time off (TOFF) is the time between photo detector output intensity changed from 10% to 90%. Note 5: Definition of color chromaticity (CIE1931). Color coordinates measured at center point of LCD. Note 6: Definition of luminance. Measure the luminance of white state at center point.
