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 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.

(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.)

CONFIDENTIAL – DO NOT COPY

File No. SG-0000034

Page 2-2

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

materials 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. 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) The conductive material and signal cables are kept away from LED driver inductor to

prevent abnormal display, sound noise and temperature rising.

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°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 could be recovered if the LCM is released at the

normal condition after the low or over the storage temperature.

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

chamois soaked with normalhexane.

Chapter 7 Theory of Circuit Operation

The route of D-SUB 15pin input

An RGB (analog) signal is inputted the D-SUB 15pin to the MT5376 which transfers it to a digital

signal by the A/D converter. Then MT5376

display device. The Extended Display Identification (EDID) code is recorded in EEPROM.

The route of HDMI CON input

A HDMI (Digital) signal is inputted the HDMI 1,2 & 3 CON to the PI3HDMI301 switch. The

passing signal is processed with the MT5376

The route of HDTV & Component input

HDTV & Component signal is inputted to the MT5376.After processing, MT5376 generates a LVDS

for display device. The audio signal is inputted MT5376

signal to audio output. an audio amplifier and line out.

The route of CVBS input

The CVBS signal is inputted to the MT5376.After processing, MT5376 generates a LVDS for

generates a Low Voltage Differential Signal (LVDS) for

. Then MT5376 generates a LVDS for display device.

. After processing, MT5376 transmits the

display device. The audio signal is also inputted MT5376

signal to audio amplifier. Then, the amplified signal is the output audio signal.

The route of TV input

TV signal is demodulated by the tuner then the demodulating signal is divided into two parts, video

and audio signal. The video signal is processed by MT5376

display device. The audio signal is transmitted in the route named SIF. The SIF signal is

demodulated and decoded by MT5376

the signal to audio amplifier. Then, the amplified signal is the output audio signal.

The route of DTV input

DTV signal demodulated by the tuner then the demodulating signal is divided into two parts, video

and audio signal. The video signal is demodulated by MT5376

transmitted to and processed by MT5376

The audio signal is transmitted in the route named FAT-IN. The FAT-IN signal is demodulated and

decoded by MT5376

amplified signal is the output audio signal.

. After processing, MT5376 transmits the signal to audio amplifier. Then, the

MT5376

Ⅰ. GENERAL DESCRIPTION

The MediaTek MT5376

integration for advanced applications. It combines a transport de-multiplexer, a high definition

video decoder, an AC3 audio decoder, a dual-link LVDS transmitter, and an NTSC/PAL/SECAM

family is a backend decoder and a TV controller and offers high

TV decoder with a 3D comb filter (NTSC/PAL). The MT5376

manufactures to build high quality, low cost and feature-rich DTV.
