Measurement System
1. Contrast Ratio(CR) is defined mathematically as :
Surface Luminance with all white pixels
Contrast Ratio = ----------------------------------------------------------
Surface Luminance with all black pixels
2. Surface luminance is the center point across the LCD surface 500mm from the
surface with all pixels displaying white. For more information see FIG 1.
3. Response time is the time required for the display to transition from white to black
(Rising Time, Tr) and from black to white (Falling Time, Tf). For additional
information see FIG 2.
4. Viewing angle is the angle at which the contrast ratio is greater than 10. The
angles are determined for the horizontal or x axis and the vertical or y axis with
respect to the z axis which is normal to the LCD surface. For more information see
FIG 3.

FIG. 2 The definition of Response Time
The response time is defined as the following figure and shall be measured by
switching the input signal for “black” and “white”.
Response Time = Rising Time(Tr) + Falling Time(Tf)
- Rising Time(Tr) : Full White 90% Æ Full White 10% Transmittance.
- Falling Time(Tf) : Full White 10% Æ Full White 90% Transmittance.
FIG. 3 The definition of Viewing Angle
Use Fig. 1(Test Procedure) under Measurement System to measure the contrast
from the measuring direction specified by the conditions as the following figure.

1) The test samples should be applied to only one test item.
2) Sample size for each test item is 5~10pcs.
3) For Damp Proof Test, pure water(Resistance>1M) should be used.
4) In case of malfunction defect caused by ESD damage, if it would be recovered to
normal state after resetting, it would be judged as a good part.
5) EL evaluation should be excepted from reliability test with humidity and
temperature: Some defects such as black spot/blemish can happen by natural
chemical reaction with humidity and fluorescence EL has.
6) After the reliability test, the test samples should be inspected after 2 hours at least.
7) Functional test is OK. Missing segment, shorts, unclear segment, non display,
display abnormally, liquid crystal leak are not allowed.
8) After testing, the current Idd should be within initial value ±20%.
9) No low temperature bubbles ,end seal loose and fall, frame rainbow, ACF bubble
growing are allowable in the appearance test.

Handing Precautions
(1) The display panel is made of glass and polarizer. As glass is fragile, it tends to
become or chipped during handling especially on the edges. Please avoid dropping
or jarring. Do not subject it to a mechanical shock by dropping it or impact.
(2) If the display panel is damaged and the liquid crystal substance leaks out, be sure
not to get any in your mouth. If the substance contacts your skin or clothes, wash it
off using soap and water.
(3) Do not apply excessive force to the display surface or the adjoining areas since this
may cause the color tone to vary. Do not touch the display with bare hands. This will
stain the display area and degraded insulation between terminals (some cosmetics
are determined to the polarizer).
(4) The polarizer covering the display surface of the LCD module is soft and easily
scratched. Handle this polarizer carefully. Do not touch, push or rub the exposed
polarizers with anything harder than an HB pencil lead (glass, tweezers, etc.). Do not
put or attach anything on the display area to avoid leaving marks on. Condensation
on the surface and contact with terminals due to cold will damage, stain or dirty the
polarizer. After products are tested at low temperature they must be warmed up in a
container before coming is contacting with room temperature air.
(5) If the display surface becomes contaminated, breathe on the surface and gently wipe
it with a soft dry cloth. If it is heavily contaminated, moisten cloth with one of the
following solvents
- Isopropyl alcohol
- Ethyl alcohol
Do not scrub hard to avoid damaging the display surface.
(6) Solvents other than those above-mentioned may damage the polarizer. Especially,
do not use the following.
- Water
- Ketone
- Aromatic solvents
Wipe off saliva or water drops immediately, contact with water over a long period of
time may cause deformation or color fading. Avoid contacting oil and fats.
(7) Exercise care to minimize corrosion of the electrode. Corrosion of the electrodes is
accelerated by water droplets, moisture condensation or a current flow in a high-
humidity environment.
(8) Install the LCD Module by using the mounting holes. When mounting the LCD
module make sure it is free of twisting, warping and distortion. In particular, do not
forcibly pull or bend the I/O cable or the backlight cable.
(9) Do not attempt to disassemble or process the LCD module.
(10) NC terminal should be open. Do not connect anything.
(11) If the logic circuit power is off, do not apply the input signals.
(12) Since LCM has been assembled and adjusted with a high degree of precision,
avoid applying excessive shocks to the module or making any alterations or
modifications to it.
- Do not alter, modify or change the shape of the tab on the metal frame.
- Do not make extra holes on the printed circuit board, modify its shape or change
the positions of components to be attached.
- Do not damage or modify the pattern writing on the printed circuit board.
- Absolutely do not modify the zebra rubber strip (conductive rubber) or heat seal
R "cmEcH RK043FN02H-CT
- Except for soldering the interface, do not make any alterations or modifications
with a soldering iron.
- Do not drop, bend or twist LCM.
Storage Precautions
When storing the LCD modules, the following precaution is necessary.
(1) Store them in a sealed polyethylene bag. If properly sealed, there is no need for the
(2) Store them in a dark place. Do not expose to sunlight or fluorescent light, keep the
temperature between 0°C and 35°C.
(3) The polarizer surface should not come in contact with any other objects. (We advise
you to store them in the container in which they were shipped).
Liquid crystals solidify under low temperature (below the storage temperature range)
leading to defective orientation or the generation of air bubbles (black or white). Air
bubbles may also be generated if the module is subject to a low temperature.
If the LCD modules have been operating for a long time showing the same display
patterns, the display patterns may remain on the screen as ghost images and a slight
contrast irregularity may also appear. A normal operating status can be regained by
suspending use for some time. It should be noted that this phenomenon does not
adversely affect performance reliability.
To minimize the performance degradation of the LCD modules resulting from destruction
caused by static electricity etc., exercise care to avoid holding the following sections
when handling the modules.
- Exposed area of the printed circuit board.
-Terminal electrode sections.
