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 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

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

Ø=0

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

(= θ6 ) as the 6 o’clock direction (“bottom”). While scanning θ and/or Ø, the

Ø=270

center of the measuring spot on the Display surface shall stay fixed. The measurement shall be executed after 30
minutes warm-up period. VDD shall be 5.0V +/-10% at 25C. Optimum viewing angle direction is 6 ’clock.

Note :

1. The value in upper table are based on BLU provided by BOEHF.

2. 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.

3. Contrast measurements shall be made at viewing angle of = 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 Appendix) Luminance Contrast Ratio (CR)
is defined mathematically.

Luminance when displaying a white raster
CR =

Luminance when displaying a black raster

4. Luminance of LCD module shall be made without signal input. Cell transmittance is defined
mathematically, BLU provided by BOEHF.

Transmittance =

5. The White luminance uniformity on LCD surface is then expressed as :

ΔY = ( Minimum Luminance of 9points / Maximum Luminance of 9points ) * 100

(See FIGURE 2 shown in Appendix).

6. 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 with BLU provided by BOEHF.

7. The electro-optical response time measurements shall be made as FIGURE 3 shown in

Appendix by switching the “data” input signal ON and OFF. The times needed for the

luminance to change from 10% to 90% is Td, and 90% to 10% is Tr.

8. 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 4
shown in Appendix).

12.0 HANDLING & CAUTIONS

(1) Cautions when taking out the open cell
 Pick the pouch only, when taking out open cell from a shipping package.
(2) Cautions for handling the open cell
 As the electrostatic discharges may break the LCD open cell, handle the LCD
open cell with care. Peel a protection sheet off from the LCD panel surface as
slowly as possible.
 As the LCD panel is made from fragile glass material, impulse and pressure to the LCD
module should be avoided.
 As the surface of the polarizer is very soft and easily scratched, use a soft dry
cloth without chemicals for cleaning.
 Do not pull the interface connector in or out while the LCD open cell is operating.
 Handle connectors and cables with care.
(3) Cautions for the operation
 When the open cell is operating, do not lose CLK, ENAB signals. If any one of

these signals is lost, the LCD panel would be damaged.

 Obey the supply voltage sequence. If wrong sequence is applied, the open cell
would be damaged.
(4) Cautions for the atmosphere
 Dew drop atmosphere should be avoided.
 Do not store and/or operate the LCD open cell in a high temperature and/or
humidity atmosphere. Storage in an electro-conductive polymer packing pouch

and under relatively low temperature atmosphere is recommended.

(5) Cautions for the open cell characteristics
 Do not apply fixed pattern data signal to the LCD open cell at product aging.
 Applying fixed pattern for a long time may cause image sticking.

(6) Other cautions

 Do not re-adjust variable resistor or switch etc.
When returning the open cell for repair or etc., Please pack the open cell not to be

broken. We recommend to use the original shipping packages.
