Shenzhen Hongguang Display Co.,Ltd 2.2 Optical Characteristics The optical characteristics are measured under stable conditions at 25℃ (Room Temperature): Item White Luminance Conditions IF= 50mA/1 LED Line (center point) Viewing Angle [degree] [degree] (Right) (Left) [degree] [degree] (Upper) (Lower) Color / Chromaticity Coordinates (CIE 1931) Color Gamut Contrast Ratio Response Time Note 1: Measurement method Equipment Pattern Generator, Power Supply, Digital Voltmeter, Luminance meter (SR_3 or equivalent) Aperture Test Point Measuring distance Module Driving Equipment Hongguang Display

Shenzhen Hongguang Display Co.,Ltd Note 2: Definition of 5 points position (Display active area: 261.12mm (H) x 163.2mm (V)) W W /4 Note 3: The luminance uniformity of 5 points is defined by dividing the minimum luminance values by the maximum test point luminance Minimum Brightness of five points δW9 = Maximum Brightness of five points Note 4: Definition of contrast ratio (CR): Brightness on the “White” state Brightness on the “Black” state Note 5: Definition of response time: The output signals of photo detector are measured when the input signals are changed from “White” to “Black” (falling...

Shenzhen Hongguang Display Co.,Ltd Note 6: Definition of viewing angle Viewing angle is the measurement of contrast ratio ≧ 10, at the screen center, over a 180° horizontal and 180° vertical range (off-normal viewing angles). The 180° viewing angle range is broken down as below: 90° (θ) horizontal left and right, and 90° (Φ) vertical high (up) and low (down). The measurement direction is typically perpendicular to the display surface with the screen rotated to its center to develop the desired measurement viewing angle. Hongguang Display
