4.0 OPTICAL SPECIFICATION

4.1 Overview

The test of Optical specifications shall be measured in a dark room (ambient luminance ≤ 1 lux and temperature =

25±2℃) with the equipment of Luminance meter system (Goniometer system and TOPCONE BM-5) and test unit shall

be located at an approximate distance 50cm from the LCD surface at a viewing angle of θ and Φ equal to 0°. We refer to

(=θ3) as the 3 o’clock direction (the “right”), θ

θ

Ø=0

the 9 o’clock direction (“left”) and θ

Ø=270

(= θ

) as the 6 o’clock direction (“bottom”). While scanning θ and/or Ø, the

6

center of the measuring spot on the Display surface shall stay fixed. The measurement shall be executed after 30
minutes warm-up period. VDD shall be 5.0V +/-10% at 25°C. Optimum viewing angle direction is 6 ’clock.

to the dark (black) state. (See FIGURE 1 shown in Appendix) Luminance Contrast Ratio (CR)

all pixels in the view field set first to white. This measurement shall be taken at the locations
shown in FIGURE 2 for a total of the measurements per display.

4. The White luminance uniformity on LCD surface is then expressed as :
ΔY = ( Minimum Luminance of 9points / Maximum Luminance of 9points ) * 100
