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 TOPCON 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 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 25C.
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 1).

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

he 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) Luminance Contrast Ratio (CR) is defined mathematically.

CR =

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 2 for a total of
the measurements per display.

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

uminance of 5(or 13) points / Maximum Luminance of 5(or 13) points.

(see FIGURE 2 and FIGURE 3).

5. The color chromaticity coordinates specified in Table 5 shall be calculated from the spe
ctral 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 4 by switc

hing the “data” input signal ON and OFF. The times needed for the luminance to change f

rom 10% to 90% is Tr, and 90% to 10% is Td.

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 5).
