LP141X3 Liquid Crystal Display

1. General Description
The LG Electronics model LP141X3 LCD is a Color Active Matrix Liquid Crystal Display with an integral Cold Cathode Fluorescent Tube(CCFT) back light system. The matrix employs a-Si Thin Film Transistor as the active element. It is a transmissive type display operating in the normally white mode. This TFT-LCD has a 14.1 inch diagonally measured active display area with XGA resolution(768 vertical by 1024 horizontal pixel array). Each pixel is divided into Red, Green and Blue subpixels or dots which are arranged in vertical stripes. Gray scale or the brightness of the sub-pixel color is determined with a 6-bit gray scale signal for each dot, thus, presenting a pallet of more than 262,144 colors. The LP141X3 LCD is intended to support applications where low power consumption, weight and thickness are critical factors and graphic displays are important. In combination with the vertical arrangement of the sub-pixels, the LP141X3 characteristics provide an excellent flat panel display for office automation products such as portable computers. This LCM has SN75LVDS86 LVDS Interface supplied by TI Japan.

At temperatures greater than 40 , the wet bulb temperature must not exceed 39 At low temperature the brightness of CCFL drop and the life time of CCFL become to be short. 2. Under no condition should the unit be exposed to corrosive chemicals.

3. Electrical Specifications
The LP141X3 requires two power inputs. One is employed to power the LCD electronics and to derive the voltages to drive the TFT array and liquid crystal. The second input which powers the backlight CCFT, is typically generated by an inverter. The inverter is an external unit to the LCD.

4. Optical Specifications
Optical characteristics are determined after the unit has been ` ON' and stable for approximately 30 minutes in a dark environment at 25C. The values specified are at an approximate distance 50cm from the LCD surface at a viewing angle of and equal to 0°. Appendix A presents additional information concerning the specified characteristics.

y axis, down (=270) 30 degree 5 Notes 1. Contrast Ratio (CR) is defined mathematically as: (Surface Brightness with all white pixels) (Surface Brightness with all black pixels) 2. Surface brightness is 5 spot average of measurement across the LCD surface 50cm from the surface with all pixels displaying white. For more information see Appendix A. 3. The variation in surface brightness, SBV is determined by measuring BON at each test position 1 through 13, and then dividing the maximum BON by the minimum BON. Maximum (BON1, BON2, ....BON13) Minimum (BON1, BON2, ....BON13) 4. Response time is the time required for the display to transition from white to black (Rise Time, TrR) and from black to white (Decay Time, TrD). For additional information see Appendix A. 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 Appendix A. 6. Color Coordinates can be changed according to color filter. (In case of changing color filter, we will tell our customer.) Revision Ver 1.0 05/ February /1998 Page6/19

11. Handling Precautions
Please pay attention to the followings when you use this TFT/LCD module with Back-light unit. 11.1.MOUNTING PREACAUTION 1)You must mount Module using mounting holes arranged in 4 corners. Be sure to turn off the power when connecting or disconnecting the circuit. 2) Note that the polarizers are easily damaged. Pay attention not to scratch or press this surface with any hard object. 3) When the LCD surface become dirty, please wipe it off with a soft material. (ie.cotton ball) 4) Protect the module from the ESD as it may damage the electronic circuit (C-MOS). Make certain that treatment person' s body are grounded thru wrist bend. 5) Do not disassemble the module and be careful not to incur a mechanical shock that might occur during installation. It may cause permanent damage. 6) Do not leave the module in high temperatures, Particularly in areas of high humidity for a long time.

Product Specification 7) The module not be expose to the direct sunlight. 8) Avoid contact with water as it may a short circuit within the module.

LP141X3 Liquid Crystal Display

11.2 OPERATING PRECAUTION 1) The spike noise causes the mis-operation of circuits. Be lower the spike noise as follows : VDD=+-200mV, V1=+-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 turn on)becomes longer. 4) Be careful for condensation at suddern temperature change. Condensation make damage to polarizer or electrical contact part. And after fading condensation, smear or spot will occur. 5) When fixed pattern are displayed at long times, remnant image is likely to occur. 6) Module has high frequency circuit. If you need to shield the electromagnetic noise. Please do in yours. 7) When Back-light unit is operating, it sounds. If you need to shield the noise, please do in yours. 11.3 ELECTROSTATIC DISCHARGE CONTROL Since module is composed with electronic circuit, it is not strong to electrostatic discharge. Make certain that treatment persons are connected to ground through list band etc.. And don' t touch I/F pin directly. 11.4 PRECAUTION FOR STRONG LIGHT EXPOSURE. Strong light exposure causes degradation of polarizer and color filter. Revision Ver 1.0 05/ February /1998 Page16/19

11.5 STORAGE When storing module as spares for long time, the following precautions are necessary. 1) Store them in a dark place : do not expose then 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.

11.6 HANDLING PRECAUTIONS FOR PROTECTION FILM 1) When the protection film is pealed off, static electricity is generated between the film and the polarizer. This film should be pealed off slowly and carefully by people who are electrically grounded and with well ionblown equipment or in such a condition. etc. 2) The protection film is attached the polarizer with a small amount of glue.If some stress is applied to rub the protection film against the polarizer during the time you peal off the film, the glue is apt to remain more on the polarizer. So please carefully peal off the protection film without rubbing it against the polarizer. 3) When the module with protection film attached is stored for long time, sometimes there remains a very small amount of glue still on the polarizer after the protaction film is pealed off. Please refrain from storing the module at the high temperature and high humidity for glue is apt to remain in these condition. 4) The glue may be taken for the modules failure, but you can remove the giue easily. When the glue 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. 11.7 SAFETY 1) If module is broken, be careful to handle not to injure. (TFT/LCD and lamp are made of glass) Please wash hands sufficiently when you touch the liquid crystal coming out from broken LCDs. 2) As it is possible for PCB or other electronic parts of module to small to smoke and to take fire becauseof the short circuit. Please design the circuit of your instrument not to flow the electric current to TFT/LCD module more than 500mA. (by apply the fuse for example) 3) As Back-light unit has high voltage circuit internal, do not open the case and do not insert foreign materials in the case.
