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.

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 Figure1).
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 Figure1). Luminance Contrast Ratio (CR) is
defined mathematically as CR = Luminance when displaying a white raster / Luminance
when displaying a black raster.
3. Reference only / Standard Front Surface Treatment Measured with green cover glass.
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.
