Product Specification

1. General Description

The LC320EXN is a Color Active Matrix Liquid Crystal Display with an integral Light Emitting Diode(LED)
backlight system. The matrix employs a-Si Thin Film Transistor as the active element.
It is a transmissive display type which is operating in the normally black mode. It has a 31.51 inch diagonally
measured active display area with WXGA resolution (768 vertical by 1366 horizontal pixel ar
Each pixel is divided into Red, Green and Blue sub-pixels or dots which are arranged in Hor izontal stripes.
Gray scale or the luminance of the sub-pixel color is determined with a 8-bit gray sca le signal for each dot,
thus presenting a palette of more than 16.7M(true) colors.
It has been designed to apply the 8-bit 1-port LVDS interface.
It is intended to support LCD TV, PCTV where high brightness, super wide viewing angle, high color gamut,
high color depth and fast response time are important.

2. Temperature and relative humidity range are shown in the figure below.
Wet bulb temperature should be Max 39°C, and no condensation of water.

3. Gravity mura can be guaranteed below 40°C condition.

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

of display area is less than or equal to 68°C 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 degraded in case of
improper thermal management in final product design.

25±2°C.

3. LGD recommend that the PWM freq. is synchronized with One time harmonic of Vsync signal of system.
Though PWM frequency is over 120Hz (max 252Hz), function of LED Driver is not affected.

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

CR =

It is measured at center 1-point.

2. 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. 2.

3. The variation in surface l umin ance , δ WHITE is defined as :

9. Precautions

Please pay attention to the followings when you use this TFT LCD module.

9-1. Mounting Precautions

(1)You must mount a module using specified mounting holes (Details refer to the drawings).
(2) You should consider the mounting structure so that uneven force (ex. Twisted stress) is not applied to the

module. And the case on which a module is mounted should have sufficient strength so that external
force is not transmitted directly to the module.

(3) 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.
(4) You should adopt radiation structure to satisfy the temperature specification.
(5) Acetic acid type and chlor ine type materials for the cover case are not des irable because the former

generates corrosive gas of attacking the polarizer at high tempe rature and the latte r causes ci rcuit br eak
by electro-chemical reaction.

(6) 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.)
(7) When the surface becomes dusty, please wipe gently with absorbent cotton or other soft mater ials 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. * There is no problem of Panel crack under 5kgf / φ10mm

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

deformations and color fading.

(9) Do not open the case because inside circuits do not have sufficient strength.

9-2. 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(requ ired time tha t br ightness is stab le after turned on ) beco mes

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 cir cuits. Sufficient suppression to the elec tromagnetic 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 acoustical impact to LCM. O therwise, LCM can ’t be operated

its full characteristics perfectly.

(8) A screw which is fastened up the steels should be a machine screw.

(if not, it causes metallic foreign material and deal LCM a fatal blow)
(9) Please do not set LCD on its edge.
(10) The conductive material and signal cables are kept away from LED driver inductor to prevent abnormal

display, sound noise and temperature rising.

9-3. Electrostatic Discharge Control

Since a module is composed of electronic circuits, it is not strong to elec trostatic di scharge. Make certain that
treatment persons are connected to ground through wrist band etc. And don’t touch interface pin directly.

9-4. Precautions for Strong Light Exposure

Strong light exposure causes degradation of polarizer and color filter.

9-5. Storage

When storing modules as spares for a long time, the following precautions are necessary.
(1) Store them in a dark place. Do not exp ose t h e mo dul e t o sunli ght or flu oresce nt light. K e ep t h e t emp erat ure

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 they be stored in the container in which they were shipped.

9-6. Handling Precautions for Protection Film

(1) The protection film is attached to the bezel with a small masking tape.

When the protection film is peeled off, static electricity is generated between the film and polarizer.
This should be peeled off slowly and care fully by people who are electrically g rounded and with well ion­blown equipment or in such a condition, etc.

(2) When the module with protection film a ttached is stored for a long time, sometimes there remains a very

small amount of glue still on the bezel after the protection film is peeled off.

(3) You can remove the glue easily. When the glue remains on the bezel surface or its ves tige is recognized,

please wipe them off with absorbent cotton waste or other soft materia l like chamois soaked with normal­hexane.
