T420HW07 V7 Product Specification

Rev. 03

1. General Description

This specification applies to the 42.0 inch Color TFT-LCD Module T420HW07 V7. This LCD module has a TFT
active matrix type liquid crystal panel 1,920x1,080 pixels, and diagonal size of 42.0 inch. This module supports
1,920x1080 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 8-bit gray scale signal for each dot.

The T420HW07 V7 has been designed to apply the 8-bit 4 channel LVDS interface method. It is intended to
support displays where high brightness, wide viewing angle, high color saturation, and high color depth are very
important.

Notes:
(1) Display position is specific by the rise of DE signal only.

Horizontal display position is specified by the rising edge of 1st DCLK after the rise of 1st DE, is displayed on the
left edge of the screen.

Frequency Fh 60 67.5 73 KHz

(2)Vertical display position is specified by the rise of DE after a “Low” level period equivalent to eight times of

horizontal period. The 1st data corresponding to one horizontal line after the rise of 1st DE is displayed at the top

line of screen.
(3)If a period of DE “High” is less than 1920 DCLK or less than 1080 lines, the rest of the screen displays black.
(4)The display position does not fit to the screen if a period of DE “High” and the effective data period do not

synchronize with each other.

3.5 Color Input Data Reference

The brightness of each primary color (red, green and blue) is based on the 8 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.

4. Optical Specification

Optical characteristics are determined after the unit has been ‘ON’ and stable for approximately 45 minutes in a
dark environment at 25°C. The values specified are at an approximate distance 50cm from the LCD surface at a
viewing angle of φ and θ equal to 0°.

Fig.1 presents additional information concerning the measurement equipment and method.

4. Response time Tγ is the average time required for display transition by switching the input signal for five
luminance ratio (0%,25%,50%,75%,100% brightness matrix) and is based on Fv=60Hz to optimize.

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

7. 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 in four corners or four sides.
(2) You should consider the mounting structure so that uneven force (ex. twisted stress) is not applied

to 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 chlorine type materials for the cover case are not desirable because the former

Rev. 03

generates corrosive gas of attacking the polarizer at high temperature and the latter cause circuit
broken by electro-chemical reaction.

(6) Do not touch, push or rub the exposed polarizer 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 materials

like chamois soaks with petroleum benzene. Normal-hexane is recommended for cleaning the
adhesives used to attach front/ rear polarizer. 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 device 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 of CCFL 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.

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 wristband 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

T420HW07 V7 Product Specification

Rev. 03

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.

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 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 or its vestige is recognized,

please wipe them off with absorbent cotton waste or other soft material like chamois soaked with

normal-hexane.
