4.0 OPTICAL SPECIFICATIONS

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-5A) 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 θ
(=θ3 ) as the 3 o’clock direction (the “right”), θ
(“upward”), θ

(= θ9 ) as the 9 o’clock direction (“left”) and θ

Ø=180

(= θ12 ) as the 12 o’clock direction

Ø=90

(= θ6 ) as the 6

Ø=270

o’clock direction (“bottom”). While scanning θ and/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. VDDshall be 3.3+/- 0.3V at 25°C. Optimum viewing angle direction is 6
o’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 (see FIGURE 1 shown in page 11).

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 page 11)
Luminance Contrast Ratio (CR) is defined mathematically.

CR =

3. The White luminance uniformity on LCD surface is then expressed.
(See FIGURE 2~3 shown in page 12)

Uniformity ΔY=

4. 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.

5. The electro-optical response time measurements shall be made as FIGURE 4 shown in page 13 by
switching the “data” input signal OFF and ON. The times needed for the luminance to change from
10% to 90% is Tr, and 90% to 10% is Td. (See FIGURE 4 shown in page 13)

6. 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 shown in page 13)

7. Measure condition: Light source is 6,000nits, 15 degree position & BLU on at Full white.
