Product Specification

1. General Description

The LC320EXJ is a Color Active Matrix Liquid Crystal Display with an integral the Source PCB and Gate
implanted on Panel (GIP). The matrix employs a-Si Thin Film Transistor as the active element.
It is a transmissive type display operating in the normally black mode. It has a 31.5 inch diagonally measured
active display area with WXGA resolution (768 vertical by 1366 horizontal pixel array).
Each pixel is divided into Red, Green and Blue sub-pixels or dots which are arranged in vertical stripes.
Gray scale or the luminance of the sub-pixel color is determined with a 8-bit gray scale signal for each dot.
Therefore, it can present a palette of more than 16.7M(6bit + A-FRC) colors.
It is intended to support LCD TV, PCTV where high brightness, super wide viewing angle, high color gamut,

3. Gravity mura can be guaranteed below 40℃ condition.

4. The maximum operating temperature is based on the test condition that the surface temperature

of display area is less than or equal to 68 ℃ with LCD module alone in a temperature controlled
chamber. Thermal management should be considered in final product design to prevent the surface

temperature of display area from being over 68 ℃. The range of operating temperature may

degrade in case of improper thermal management in final product design.

1. All GND (Ground) pins should be connected together to the LCD module’s metal frame.

2. All VLCD (power input) pins should be connected together.

3. All Input levels of LVDS signals are based on the EIA 644 Standard.

4. These pins are used only for LGD (Do not connect)

5. Specific pin No. #30 is used for “No signal detection” of system signal interface.

It should be GND for NSB (No Signal Black) while the system interface signal is not.

If this pin is “H”, LCD Module displays AGP (Auto Generation Pattern).

The brightness of each primary color (Red, Green, Blue) is based on the 8-bit gray scale data input for the color.
The higher binary input, the brighter the color. Table 5 provides a reference for color versus data input.

2. If T2 is satisfied with specification after removing LVDS Cable, there is no problem.

3. The T3 / T4 is recommended value, the case when failed to meet a minimum specification,
abnormal display would be shown. There is no reliability problem.

4. T5 should be measured after the Module has been fully discharged between power off and on period.

5. If the on time of signals (Interface signal and user control signals) precedes the on time of Power (V
it will be happened abnormal display. When T6 is NC status, T6 doesn’t need to be measured.

6. It is recommendation specification that T7 has to be 0ms as a minimum value.

Note :

1. Contrast Ratio(CR) is defined mathematically as :

LC320EXJ

Contrast Ratio =

Surface Luminance with all white pixels

Surface Luminance with all black pixels

It is measured at center 1-point.

※. Surface luminance is determined after the unit has been ‘ON’ and 1Hour after lighting the

backlight in a dark environment at 25±2°C. Surface luminance is the luminance value at center
1-point across the LCD surface 50cm from the surface with all pixels displaying white.
For more information see the FIG. 3.

2. Response time is the time required for the displa

to transit from any gray to white (Rise Time, Tr)

and from any gray to black (Decay time, TrD). For additional information see the FIG. 4.

10. Precautions

.

10-1. Assembly Precautions

(1) Please attach the surface transparent protective plate to the surface in order to protect the polarizer.

Transparent protective plate should have sufficient strength in order to the resist external force.
(2) You should adopt radiation structure to satisfy the temperature specification.
(3) Acetic acid type and chlorine type materials for the cover case are not desirable because the former

generates corrosive gas of attacking the polarizer at high temperature and the latter causes circuit break

.

(4) Do not touch, push or rub the exposed polarizers with glass, tweezers or anything harder than HB

pencil lead. And please do not rub with dust clothes with chemical treatment.

Do not touch the surface of polarizer for bare hand or greasy cloth.(Some cosmetics are detrimental

to the polarizer.)
(5) When the surface becomes dusty, please wipe gently with absorbent cotton or other soft materials like

chamois soaks with petroleum benzine. Normal-hexane is recommended for cleaning the adhesives
used to attach front / rear polarizers. Do not use acetone, toluene and alcohol because they cause
chemical damage to the polarizer

(6) Wipe off saliva or water drops as soon as possible. Their long time contact with polarizer causes

deformations and color fading.
(7) Board ass’y should be put on the mold frame properly.
(8) FFC Cable should be connected between System board and Source PCB correctly.
(9) Mechanical structure for backlight system should be designed for sustaining board ass’y safely.

10-2. Operating Precautions

(1) The spike noise causes the mis-operation of circuits. It should be lower than following voltage :

V=±200mV(Over and under shoot voltage)

(2) Response time depends on the temperature.(In lower temperature, it becomes longer.)
(3) Brightness depends on the temperature. (In lower temperature, it becomes lower.)

And in lower temperature, response time(required time that brightness is stable after turned on)
becomes longer

(4) Be careful for condensation at sudden temperature change.Condensation makes damage to polarizer or

electrical contacted parts. And after fading condensation, smear or spot will occur.

(5) When fixed patterns are displayed for a long time, remnant image is likely to occur.
(6) Module has high frequency circuits. Sufficient suppression to the electromagnetic interference shall be

done by system manufacturers. Grounding and shielding methods may be important to minimized the
interference.

(7) Please do not give any mechanical and/or electrical impact to board assy. Otherwise, it can’t be operated

its full characteristics perfectly.

10-3. Electrostatic Discharge Control

Since a module is composed of electronic circuits, it is not strong to electrostatic discharge. Make certain that
treatment persons are connected to ground through wrist band etc. And don’t touch interface pin directly.
Panel ground path should be connected to metal ground.

10-4. Precautions for Strong Light Exposure

Strong light exposure causes degradation of polarizer and color filter.

10-5. Storage

When storing the board ass’y as spares for a long time, the following precautions are necessary.

(1) Store them in a dark place. Do not expose the board ass’y to sunlight or fluorescent light. Keep the

temperature between 5°C and 35°C at normal humidity.

(2) The polarizer surface should not come in contact with any other object.

It is recommended that the

be stored in the container in which they were shipped.

10-6. Operating condition guide

(1) The LCD product should be operated under normal conditions. Normal condition is defined as below;

- Temperature : 5 ~ 40 ℃, normal humidity

- Display pattern : continually changing pattern (Not stationary)

(2) If the product will be used in extreme conditions such as high temperature, display patterns or operation

..,
It is strongly recommended to contact LGD for Qualification engineering advice. Otherwise, its reliability
and function may not be guaranteed. Extreme conditions are commonly found at Airports, Transit Stations,
Banks, Stock market, and Controlling systems. The LCD product should be applied by global standard

environment. (refer ETSI EN 300, IEC 60721)
