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.

2. Maximum Ratings
The following are maximum values which, if exceeded, may cause faulty operation or damage to the unit. Table 1 ABSOLUTE MAXIMUM RATINGS Parameter Power Input Voltage Logic Input Voltage Operating Temperature symbol Min.

C Storage Temperature -20 +60 TST Note: 1. The Relative Humidity must not exceed 80% non-condensing at temperatures of 40 C or less. At temperatures greater than 40 C , the wet bulb temperature must not exceed 39 C . 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.
