4.0 OPTICAL SPECIFICATION

4.1 Overview

The test of optical specifications shall be measured in a dark room (ambient luminance d 1 lux and

temperature = 25r2ć) with the equipment of luminance meter system (PR730&PR810) 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 0q. We refer to θØ=0 (=θ3 ) as the 3 o’clock direction (the “right”), θØ=90 (= θ12 ) as the 12

o’clock direction (“upward”), θØ=180 (= θ9 ) as the 9 o’clock direction (“left”) and θØ=270(= θ6 ) as

the 6 o’clock direction (“bottom”). While scanning θand/or Ø, the center of the measuring spot on the

display surface shall stay fixed. The backlight should be operating for 30 minutes prior to measurement.

VDD shall be 3.3+/- 0.3V at 25qC. Optimum viewing angle direction is 6 ’clock.

Notes :

1. Viewing angle is the angle at which the contrast ratio is greater than 10. The viewing angles are

determined for the horizontal or 3, 9 o’clock direction and the vertical or 6, 12 o’clock direction

with respect to the optical axis which is normal to the LCD surface (see Figure 7).

2. Contrast measurements shall be made at viewing angle of Θ= 0 and at the center of the LCD

surface. Luminance shall be measured with all pixels in the view field set first to white, then to the

dark (black) state . (see Figure 7) Luminance Contrast Ratio (CR) is defined mathematically.

3. Center Luminance of white is defined as luminance values of 5 point average across the LCD

surface. Luminance shall be measured with all pixels in the view field set first to white. This

measurement shall be taken at the locations shown in Figure 8 for a total of the measurements per

display.

4. The White luminance uniformity on LCD surface is then expressed as : ΔY =Minimum Luminance

of 5(or 13) points / Maximum Luminance of 5(or 13) points.(see Figure 8 and Figure 9).

5. The color chromaticity coordinates specified in Table 5 shall be calculated from the spectral data

measured with all pixels first in red, green, blue and white. Measurements shall be made at the center

of the panel.

6. The electro-optical response time measurements shall be made as Figure 10 by switching the “data”

input signal ON and OFF. The times needed for the luminance to change from 10% to 90% is T

f, and

90% to 10% is T

7. Cross-Talk of one area of the LCD surface by another shall be measured by comparing the luminance

(YA) of a 25mm diameter area, with all display pixels set to a gray level, to the luminance (YB) of

that same area when any adjacent area is driven dark. (See Figure 11).
