5 LM5X2C2TH. General Descriptions The LG Electronics model LM5X2 LCD is a Color Active Matrix with an integral Cold Cathode Fluorescent Tube(CCFT) back light system. The matrix employs asi Thin Film Transistor as the active element. It is a transmissive type display operating in the normally white mode. This TFTLCD has a 5. inch diagonally measured active display area with XGA resolution(768 vertical by 24 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 subpixel color is determined with a 6bit gray scale signal for each dot, thus, presenting a palette of more than 262,44 colors. LM5X2 has been designed to apply the CMOS logic level interface. The LM5X2 LCD is intended to support applications where high brightness, wide viewing angle, high color saturation, and high color depth are very important. In combination with the vertical arrangement of the subpixels, the LM5X2 characteristics provide an excellent flat panel display for office automation products such as monitors.

19 LM5X2C2TH 4. PRECAUTIONS Please pay attention to the followings when you use this TFTLCD module with Backlight unit. )You must mount Module using mounting holes arranged in 4 corners. 2) Be sure to turn off the power when connecting or disconnecting the circuit. 3) Note that the polarizers are easily damaged. Pay attention not to scratch or press this surface with any hard object. 4) When the LCD surface become dirty, please wipe it off with a soft material. (ie. cotton ball) 5) Protect the module from the ESD as it may damage the electronic circuit (CMOS). Make certain that treatment person s body are grounded through wrist bend. 6) Do not disassemble the module and be careful not to incur a mechanical shock that might occur during installation. It may cause permanent damage. 7) Do not leave the module in high temperatures, particularly in areas of high humidity for a long time. 8) The module not be expose to the direct sunlight. 9) Avoid contact with water as it may a short circuit within the module. ) Do not apply invalid signal, especially very high frequency data clock and Hsync. Invalid signal causes improper shutdown of DC/DC converter in LCM or permanent damage to LCD module. (If DC/DC converter in LCM is in shutdown state, LCM shows only white screen. Then please turn off and on once LCM power.) ) If the LCM displays the same pattern continuously for a long period of time, it can be the image sticking to the screen.
