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 θ
o’clock direction (“upward”), θ
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 +/-

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)
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)

3. Luminance of white is defined as a center point (1) on 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. (See FIGURE 2)
