4.0 OPTICAL SPECIFICATION

4.1 Overview

The test of optical specifications shall be measured in a dark room (ambient luminance﹤1 lux
andtemperature=25±2℃) with the equipment of Luminance meter system (Goniometer system and PR730) 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 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 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 12.0V +/-10%
at 25℃. Optimum viewing angle direction is 6 ‟clock.

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.

2. 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 Figure1 shown in Appendix) Luminance Contrast Ratio (CR) is defined mathematically.

3.Center Luminance of white is defined as the LCD surface. Luminace 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 measurement per
display。

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

ΔY = ( Minimum Luminance of 5points / Maximum Luminance of 5points ) * 100 (See Figure 2 shown in

Appendix).

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. Response time Tg is the average time required for display transition by switching the input signal as below
table and is based on Frame rate fV =60Hz to optimize. Each time in below table is defined as Figure 2and shall
be measured by switching the input signal for “any level of gray(bright)”and “any level of gray(dark)”.

7. Definition of Transmittance (T%) :
Module is with white(L255) signal input

11.0 RELIABLITY TEST

The Reliability test items and its conditions are shown in below.

< Table 13. Reliability Test Condition >

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.

ity

Environment

Method

●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.

Note:
(1)Measurement Setup
The LCD module should be stabilized at 25℃ for 30 minutes to avoid abrupt
temperature change during measuring. In order to stabilize the luminance, the measurement should be executed after
lighting backlight for 30 minutes in a windless room.
