Transmission White Chromaticity Shift Brightness
Note 1 : Ambient temperature =25℃ Note 2 : To be measured in the dark room. Note 3 : To be measured on the center area of panel with a field angle of 1℃ by Topcon luminance meter BM-7, after 10minutes operation. Note 4 : Definition of Response time The output signals of photo detector are measured when the input signals are changed from “ black” to “white” (falling time) and from “white” to “black” (rising time), respectively. The response time is defined as the time interval between the 10% and 90% of amplitudes. Refer to figure as below.

Note 5 : Definition of Contrast Ratio Contrast Ratio is calculated with the following formula. Contrast Ratio (CR) = Brightness measured when LCD is at “white state” Brightness measured when LCD is at “black state”
Note 6 : White Vi=Viso -/+1.5V Black Vi=Viso ± 2.0V “±”means that the analog input signal swings in phase with COM signal. “-/+” means that the analog input signal swings out of phase with COM signal. Vsio : The analog input voltage when transmission of LCD panel when all the input terminals of module are electrically opened. Note 7 : Definition of Viewing Angle Refer to the figure as below.
Note 8 : Measured at the center area of the panel when all the input terminals of LCD panel are electrically opened.
