TAILOR PIXELS TECHNOLOGY CO., LTD. 6.2.2 Driving Backlight Item Forward Current Forward Voltage Note 1: Each LED: IF =20 mA, VF =3.2V. Note 2: Optical performance should be evaluated at Ta=25℃ only. Note 3: If LED is driven by high current, high ambient temperature & humidity condition. The lifetime of LED will be reduced. Operating life means brightness goes down to 50% initial brightness. Typical operating lifetime is estimated data.

TAILOR PIXELS TECHNOLOGY CO., LTD. 7 Optical Characteristics Items Viewing angles Contrast Ratio Response Time Chromaticity White Color Gamut Luminance Test Conditions: 1. DvDD=3.3V, the ambient temperature is 25°C. 2. The test systems refer to Note 1 and Note 2. Note 1: Definition of optical measurement system. The optical characteristics should be measured in the darkroom. After 5 minutes of operation, the optical properties are measured at the center point of the LCD screen. All input terminals LCD panel must be ground when measuring the center area of the panel.

TAILOR PIXELS TECHNOLOGY CO., LTD. Note 2: Definition of viewing angle range and measurement system. Viewing angle is measured at the center point of the LCD by CONOSCOPE (ergo-80). Note 3: Definition of contrast ratio Note 4: 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% Note 5: Definition of color...
