1. General Description
The LC320WXE is a Color Active Matrix Liquid Crystal Display with an integral External Electrode F luorescent
Lamp(EEFL) backlight system. The matrix employs a-Si Thin Film Transistor as the active element.
It is a transmissive type display operating in the normally b lack mode. It has a 31.51 inch diagonally measu red
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 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(6bit+AFRC) 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.

Note
The design of the inverter must have specifications for the lamp in LCD Assembly.
The electrical characteristics of inverter are based on High-High Driving type.
The performance of the lamps in LCM, for ex am pl e life time or bright ne ss, is extremely influe n ce d by th e
characteristics of the DC-AC inverter. So, all the parameters of an inverter should be carefully designed so
as not to produce too much leakage current from high-voltage output of the inverter.
When you design or order the inverter, please make sure unwanted lighting caused by the mismatch of the
lamp and the inverter (no lighting, flicker, etc) has never been occurred. When you confirm it, the LCD–
Assembly should be operated in the same condition as installed in your instrument.
※ Do not attach a conductive tape to lamp connecting wire.
If you attach conductive tape to the lamp wire, not only luminance level can be lower than typical one but
also inverter operate abnormally on account of leakage current which is generated between lamp wire and
conductive tape.
1. Specified values are defined for a Backlight Assembly.( IBL : 10 lamp, 6.5 mA/Lamp)
2. Operating voltage is measured at 25 ± 2°C(after 2hr.aging).The variance range for operating voltage
is ± 10%.

Otherwise, the lamps may not be turned on. The used lamp current is typical value.
When the Striking Frequency is higher than the Operating Frequency , the parasitic capacitance
can cause inverter shut down, therefore It is recommended to check it.
4. Lamp frequency may produce interference with horizontal synchronous frequency.As a result this may
cause beat on the display. Therefore, lamp frequency shall be away as much as possible from the
horizontal synchronous frequency and its harmonics range in order to prevent interference.

Typical level of power consumption is measured after 2hrs aging at 25 ± 2°C.
7. The life time is determined as the time at which brightness of the lamp is 50% compared to that of initia
value at the typical lamp current on condition of continuous operating at 25 ± 2°C, based on duty 100%.

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 7 provides a reference for color versus data input.
1. Even though T1 is over the specified value, there is no problem if I2T spec of fuse is satisfied.
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. If there is no abnormal display, no problem.
7. It is recommendation specification that T8 has to be 100ms as a minimum value.
※ Please avoid floating state of interface signal at invalid period.
※ When the power supply for LCD (VLCD) is off, be sure to pull down the valid and invalid data to 0V.

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.
(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(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 acoustical impact to LCM. Otherwis e, 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 can causes conductive particles 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 transformers to prevent abnormal display,
sound noise and temperature rising.
(11) Partial darkness may happen during 3~5 minutes when LCM is operated initially in condition that
luminance is under 40% at low temperature (under 5℃). This phenomenon which disappears naturally
after 3~5 minutes is not a problem about reliability but LCD characteristic.
Ver. 1.1
28 /44
LC320WXE
Product Specification
(12) Partial darkness may happen under the long-term operation of any dimming without power on/off.
This phenomenon which disappears naturally after 5 minutes is not a problem about reliability but
LCD characteristics.
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.
(3) Storage condition is guaranteed under packing conditions.
(4) The phase transition of Liquid Crystal in the condition of the low or high storage temperature will be
recovered when the LCD module returns to the normal condition
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 ion-
blown 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 vestige is r ecognized,
please wipe them off with absorbent cotton waste or other soft materia l like chamois soaked with normal-
hexane.
9-7. Operating condition guide
(1) The LCD product should be operated under normal conditions. Normal condition is defined as below;
(2) If the product will be used in extreme conditions such as high temperature, display patterns or operation
time etc..,
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)

Mega DCR using condition(1)
After Inverter ON signal, PWM Duty 100% should be sustained during 2sec.
It is recommended not to sustain more than 10 min for Deep Dimming
(Inverter output Low Duty 0%~20%).
The deep dimming must be used very carefully due to limitation of lamp characteristics and specification.
1) For stable lamp on, its duty condition should follow below the condition.
After Inverter ON signal, T0 duration should be sustained.

2) Low duty(0%~20%) of the inverter output current, B/L may not satisfy some of LCM specification.
- Duration : the low duty operation(0 ~ 20%) must be limited within 10 minutes for one time operation.
- Ratio : the period of the low duty operation must be less than 1/5 compare to that of the high duty
operation(20~Max duty%) in a certain period to prevent unwanted operation.
- FOS : partial darkness or darkness of center area during the low duty might be happened due to
insufficient lamp current.
Min 3[min]
- Warm up : the low duty must be used 3 min after the lamps “ON”. In case of low temperature, more
warm up time may be needed.
