1. GENERAL DESCRIPTION

This specification applies to the 42.02 inch Color TFT-LCD SKD model T420HVN04.2. This LCD Open Cell Unit

has a TFT active matrix type liquid crystal panel 1,920x1,080 pixels, and diagonal size of 42.02 inch. This Open

Cell Unit supports 1,920x1,080 mode. 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 10-bit gray

scale signal for each dot.

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.

5. Light source here is the standard light source “C” which is defined by CIE and driving voltages are based on

suitable gamma voltages. The calculating method is as following：

A. Measure the “Module” and “BLU” optical spectrums (W, R, G, B).

B. Calculate cell spectrum from “Module” and “BLU” spectrums.

C. Calculate color chromaticity by using cell spectrum and the spectrum of standard light source “C”.

6. 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 FIG4.

7. PRECAUTIONS

Please pay attention to the followings when you use this TFT LCD Open Cell unit.

7.1 MOUNTING PRECAUTIONS

(1) You should consider the mounting structure so that uneven force (ex. Twisted stress) is not applied to the cell. And the frame on which a cell is mounted should have sufficient strength so that external force is not transmitted directly to the cell.

(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.

(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 by electro-chemical reaction. (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 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. (6) Wipe off saliva or water drops as soon as possible. Their long time contact with polarizer causes deformations and color fading. (7) Do not open the case because inside circuits do not have sufficient strength.

Rev.1.0

7.2 OPERATING PRECAUTIONS

(1) The open cell unit listed in the product specification sheets was designed and manufactured for TV

application

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

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

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

(4) Brightness/transmittance 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.

(5) 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.

(6) When fixed patterns are displayed for a long time, remnant image is likely to occur.

(7) 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 minimize the

interface.

7.3 ELECTROSTATIC DISCHARGE CONTROL

Since a open cell unit 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.

7.4 PRECAUTIONS FOR STRONG LIGHT EXPOSURE

Strong light exposure causes degradation of polarizer and color filter.

TXXXHW0X Vx Product Specification

7.5 STORAGE

When storing open cell units as spares for a long time, the following precautions are necessary.

(1) Store them in a dark place. Do not expose the open cell unit to sunlight or fluorescent light. Keep the

Rev.1.0

temperature between 5 and 35 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.

℃ ℃

7.6 HANDLING PRECAUTIONS FOR PROTECTION FILM OF POLARIZER

The protection film of polarizer is still attached on the surface as you receive open cell units. When the

protection film is peeled off, static electricity is easily generated on the polarizer surface. 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.
