4.0 OPTICAL SPECIFICAT ION

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

Ø=0

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

(= θ6 ) as the 6 o’clock direction (“bottom”). While scanning θ and/or Ø, the

Ø=270

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.

Note :

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

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 1 shown in Appendix) Luminance Contrast Ratio (CR) is defined mathematically.

CR =

3. Center Luminance of white is defined as 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 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 (See FIGURE 2 shown in Appendix).

5. The color chromaticity coordinates specified in Table 4. 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 3 shown in Appendix by switching the “data” input signal ON and OFF. The times needed for the luminance to change from 10% to 90% is Td, and 90% to 10% is Tr.

7. Cross-Talk of one area of the LCD surface by another shall be measured by comparing the luminance (Y luminance (YB) of that same area when any adjacent area is driven dark. (See FIGURE 4 shown in Appendix).
