1. General Description

This specification applies to the 42 inch Color TFT-LCD Module T420HW05 V3. This LCD module has

a TFT active matrix type liquid crystal panel 1920x1080 pixels, and diagonal size of 42 inch. This

module supports 1920x1080 Full-HD mode (Non-interlace).

Each pixel is divided into Red, Green and Blue sub-pixels or dots which are arranged in vertical stripes.

Gray scale or the brightness of the sub-pixel color is determined with a 8-bit+FRC gray scale signal for

each dot.

The T420HW05 V3 has been designed to apply the 10-bit 4 channel LVDS interface method. It is

intended to support displays where high brightness, wide viewing angle, high color saturation, and

3. Electrical Specification

The T420HW05 requires two power inputs. One is employed to power the LCD electronics and to drive

the TFT array and liquid crystal. The second input, which powers the CCFL, is typically generated by

an inverter.

3-5 Color Input Data Reference

The brightness of each primary color (red, green and blue) is based on the 10 bit gray scale data input

for the color; the higher the binary input, the brighter the color. The table below provides a reference for

color versus data input.

Apply the lamp voltage within the LCD operating range. When the backlight turns on before the LCD

operation or the LCD turns off before the backlight turns off, the display may momentarily become

abnormal.

Caution : The above on/off sequence should be applied to avoid abnormal function in the display. In

case of handling, make sure to turn off the power when you plug the cable into the input connector or

pull the cable out of the connector.

5. 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. 4-3. (Optical measurement by SR3)

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 holes arranged on back side of panel.

(2) 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.

(3) You should adopt radiation structure to satisfy the temperature specification.

(4) 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 by electro-chemical reaction.

(5) 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.)

(6) When the surface becomes dusty, please wipe gently with absorbent cotton or other soft

materials like chamois soaks with petroleum benzene. 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.

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

causes deformations and color fading.

(8) 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:



200mV(Over and under shoot voltage)

V=

(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

www.panelook.com

shall be done by system manufacturers. Grounding and shielding methods may be important

to minimize the interface.

9-3 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.

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 sunlight or fluorescent light. Keep the

temperature between 5

(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.

к

and 35к at normal humidity.

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 carefully by people who are electrically grounded and with well ion-blown

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 small amount of flue 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 or its vestige is

recognized, please wipe them off with absorbent cotton waste or other soft material like

chamois soaked with normal-hexane.
