MACLIGHT DISPLAY CO., LIMITED Note 4: Definition of contrast ratio.( Test LCD using DMS501) Brightness of selected dots Brightness of non  selected dots Note 5: Definition of Response time. (Test LCD using DMS501): TThe 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.
