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 (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 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 1).
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) Luminance Contrast Ratio (CR) is defined mathematically.
Luminance when displaying a white raster
CR =
Luminance when displaying a black raster
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 Luminance 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 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 4
by switching the “data” input signal ON and OFF. The times needed for the
luminance to change from 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).
