Note 2: Definition of optical measurement system.
The optical characteristics should be measured in dark room. After 30 minutes operation, the optical properties are
measured at the center point of the LCD screen. (Response time is measured by Photo detector TOPCON

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 (TON) is the time between photo detector output intensity changed from 90% to 10%. And fall time (TOFF) is the
time between photo detector output intensity changed from 10% to 90%.
