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

(= θ12) as the 12 o’clock direction (“upward”), θ

Ø=90

(= θ6 ) as the 6 o’clock direction (“bottom”). While

Ø=270

scanning θ and/or Ø, the 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 BOEDT

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.

CR =

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

Luminance when displaying a white raster
Luminance when displaying a black raster

Transmittance =

5. Center Luminance of white is defined as 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.

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

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

(See FIGURE 2 shown in Appendix).

7. The color chromaticity coordinates specified in above Table 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
BOEDT.

8. 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.

9. 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).

● 200 ms  T6

Notes:

1. When the power supply VDD is 0V, keep the level of input signals on
the low or keep high impedance.

2. Do not keep the interface signal high impedance when power is on.

3. Back Light must be turn on after power for logic and interface signal are valid.

12.0 HANDLING & CAUTIONS

(1) Cautions when taking out the module

 Pick the pouch only, when taking out module from a shipping package.

(2) Cautions for handling the module

 As the electrostatic discharges may break the LCD module, handle the LCD

module with care. Peel a protection sheet off from the LCD panel surface as
slowly as possible.

 As the LCD panel and back - light element are 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 module is operating.
 Put the module display side down on a flat horizontal plane.
 Handle connectors and cables with care.

(3) Cautions for the operation

 When the module 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 module

would be damaged.

(4) Cautions for the atmosphere

 Dew drop atmosphere should be avoided.
 Do not store and/or operate the LCD module 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 module characteristics

 Do not apply fixed pattern data signal to the LCD module at product aging.
 Applying fixed pattern for a long time may cause image sticking.

(6) Other cautions

 Do not disassemble and/or re-assemble LCD module.
 Do not re-adjust variable resistor or switch etc.
When returning the module for repair or etc., Please pack the module not to be

broken. We recommend to use the original shipping packages.
