LM181E1-J3MN

Liquid Crystal Display

Product Specification

1. General Description

The LM181E1-J3MN is a Color Active Matrix Liquid Crystal Display with an integral Cold Cathode Fluorescent Lamp(CCFL) back light system. The m atrix employs a-Si Thin F ilm Transistor as the active element. It is a transmissive type display operating in the normally black mode. T his TFT -LCD has a 18.1 inch diagonally measured active display area with SXGA resolution(1024 vertic al by 1280 horizontal pixel array). Each pixe l 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 s ignal for each dot, thus, presenting a palette of more than 16,777,216 colors.

The LM181E1-J3MN has been designed to apply the interface method that enables low power, high speed low EMI. FPD Link must be used as a LVDS(Low Voltage Differential Signaling) chip.

The LM181E1-J 3MN is intended to support applications where thin thic kness, wide viewing angle, low power are critical factors and graphic dis plays are important. In c ombination with the vertical arrangement of the sub-pixels, the LM181E1-J3MN characteristics provide an excellent flat panel display for office automation products such as monitors.

3. Electrical Specifications 3-1. Electrical Characteristics

The LM181E1-J3MN requires two power inputs. One is employed to power the LCD electronics and to drive the TFT array and liquid crystal. The other input which powers the CCFL, is typically generated by an inverter. The inverter is an external unit to the LCD.

Note)The design of the inverter must have specifications for the lamp in LCD Assembly.

The performance of the Lamp in LCM, for example life time or brightness, is extremely influenced by the characteristics of the DC-AC Inverter. So all the parameters of an inverter should be carefully designed so as not to produce too much leakage current from high-voltage output of the inverter. When you design or order the inverter, please make sure unwanted lighting caused by the mismatch of the lamp and the inverter(no lighting, flicker, etc) never occurs. When you confirm it, the LCD Assembly

should be operated in the same condition as installed in your instrument Notes:1. The current draw and power consumption specified is for 12.0 Vdc at 25and fv at 60Hz. (at 8-gray pattern displayed)

2. The variance of the voltage is 10%.

3. The output voltage at the transformer in the inverter must be high considering to the loss of the

ballast capacitor in the inverter.

4. The output of the inverter must have symmetrical(negative and positive) voltage waveform and symmetrical current waveform.(Unsymmetrical ratio is less than 10%) Please do not use the inverter which has unsymmetrical voltage and unsymmetrical current and spike wave.

Lamp frequency may produce interference with horizontal synchronous frequency and as a result

this may cause beat on the display. Therefore lamp frequency shall be as away as possible from the horizontal synchronous frequency and from its harmonics in order to prevent interference.

5. The lamp power consumption shown above does not include loss of external inverter.

6. Let’s define the brightness of the lamp after being lighted for 5 minutes as 100%.

T

is the time required for the brightness of the center of the lamp to be not less than 95%.

s

7. The life time is determined as the time at which brightness of lamp is 50% compare to that of

initial value at the typical lamp current on condition of continuous operating at 25 2.

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 user holes arranged in four corners. (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 with a transparent protective plate in order to protect the polarizer LC cell. Transparent protective plate should have sufficient strength in order to 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 polarizer with glass, tweezers or anything harder than HB pencil head 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 soaked 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 spike noise causes the malfunction 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) A module has high frequency circuit. If you need to shield the electromagnetic noise, please do co-work together.

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 I/F pin directly.

9.4 PRECAUTION 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 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) 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) The protection film is attached to the polarizer with a small amount of adhesive tape. If some stress is applied to rub the protection film against the polarizer during the time you peel off the film, the adhesive tape is apt to remain on the polarizer. Please carefully peel off the protection film without rubbing it against the polarizer. (3) When the module with protection film attached is stored for a long time, sometimes there remains a very small amount of adhesive tape still on the polarizer after the protection film is peeled off. (4) You can remove the adhesive easily. When the adhesive remains on the polarizer surface or its vestige is recognized, please wipe them off with absorbent cotton waste or other soft material like chamois soaked with normal- hexane.
