Shenzhen Hongguang Display Co.,Ltd Note 1: Definition of viewing angle range Normal line θ=Φ=0° Φ=270° 6 o’clock direction Fig. 4-1 Definition of viewing angle 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 BM-7, other items are measured by BM-5A/Field of view: 1° /Height: 500mm.) Photo detector Normal line θ=Φ=0° Φ=90° 12 o’clock direction Φ=0° Active Area LCM Φ=270° 6 o’clock...

Shenzhen Hongguang Display Co.,Ltd 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%. Photo detector output (Relative value) Fig. 4-3 Definition of response time Note 4: Definition of contrast ratio Contrast ratio (CR) = Luminance measured when LCD on the " White" state Luminance measured when LCD on the " Black"...
