The LC260WX2 is a Color Active Matrix Liquid Crystal Display with an integral External Electrode
Fluorescent Lamp(EEFL) backligh t system. The matrix employs a-Si Thin Film Transistor as the active
element. It is a transmissive type display operating in the normally black mode . This TFT-LCD has a 26.0
inch diagonally measured active display area with WX GA 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 i s determined with a 8-bit gray scale signal for
each dot, thus, presenting a palette of more than 16.7M(True) colors. The LC260WX2 has been designed to
apply the LVDS interface. It is intended to support LCD TV, PC TV where high brightness, super wide
viewing angle, high color gamut, high color depth, and fast response time are important.

Notes :
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. Specific pins(pin No. #10, #27~#28) are used for DCR function of the LCD module.
If not used, these pins are no connection.
5. Specific pin No. #30 is used for “No signal detection” of system signal interface.
It should be GND for NSB(No Signal Black) during the system interface signal is not.
If this pin is “H”, LCD Module displays AGP(Auto Generation Pattern).
Table 6 shows the signal timing required at the input of the LVDS transmitter. All of the interface signal
timings should be satisfied with the following specification for normal operation.

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 usin g 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 shou ld have sufficient strength so that external
force is not transmitted directly to the module.
(3) Please attach the surface transpare nt protec t ive pl ate t o the surf ac e in order to pr ot ect the p o larizer.
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 chlorine type materials for the cover case are not desirable because the former
generates corrosive gas of attac king the pola rizer a t h igh tempe rature and the la tter cause s c irc ui t 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 a re detrimental
to the polarizer.)
(7) When the surface becomes dusty, please wipe gently with absorbent cotton or other soft mate rials 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.
www.jxlcd.com
www.jxlcd.com
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 shal l be
done by system manufacturers. Grounding and shielding me thods may be important to minimized the
interference.
(7) Please do not give any mechanical and/or acoustical i mpact to LCM. Otherwise, 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) It is recommended to avoid the signal cable and conductive material over the inverter transformer
for it can cause the abnormal display 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

9-3. Electrostatic Discharge Control
Since a module is composed of electronic circuits, i t is not strong to electros tatic di scharge. Make certai n 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 expose the module to sunligh t or fluores cent lig ht. Ke ep th e tem perat ur e
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 careful ly by people who are electri cally grounded and with we ll ionblown equipment or in such a condition, etc.
(2) When the module with protection film attached is stored for a long time, sometimes there remains a very
www.jxlcd.com
www.jxlcd.com
small amount of glue still on the bezel after the pr o t ecti on film is peeled off.
(3) You can remove the glue easily. When the glue rema ins on the beze l surfa ce or i ts ve stige is recogn i zed,
please wipe them off with absorbent cotton waste or other soft material like chamois soaked with normalhexane.

“Gray (N) ” and “Gray(M)”.(32Gray Step at 8bit)
2. G to G Uniformity
The variation of G to G Uniformity , δ
G to G Uniformity =
*Maximum (GtoG) means maximum value of measured time (N, M = 0 (Black) ~ 255(White), 32 gray step).
