1. General Description
The LG Electronics model LP133X1 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 13.3 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 sub-pixels 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 palette of more than 262,144 colors. LP133X1 has been designed to apply the interface method that enables low power, high speed low EMI. Flat Link must be used as a LVDS(Low Voltage Differential Signaling) chip. The LP133X1 LCD is intended to support applications where thin thickness, low power are critical factors and graphic displays are important. In combination with the vertical arrangement of the sub-pixels, the LP133X1 characteristics provide an excellent flat panel display for office automation products such as Notebook PC.

The Relative Humidity must not exceed 95% non-condensing at temperatures of 40 or less. At temperatures greater than 40, the wet bulb temperature must not exceed 39.
3. Electrical Specifications
The LP133X1 requires two power inputs. One is employed to power the LCD electronics and to drive 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. Table 2 Parameter ELECTRICAL CHARACTERISTICS: Values Symbol Min.

4. Optical Specifications
Optical characteristics are determined after the unit has been `ON' and stable for approximately 30 minutes in a dark environment at 25. 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 concerening the speciffied charateristics.

CIE Color Coordinates
1. Contrast Ratio (CR) is defined mathematically as:
2. Surface brightness is the average of 5 measurement across the LCD surface 50cm from the surface with all pixels displaying white. 3. The variation in surface brightness, SBV is determined by measuring BON at each test position 0 through 9, and then dividing the maximum BON of 9 points luminance by minimun BON of 9 points luminance. SBv = Maximum (BON0, BON1, ....BON9) Minimum (BON0, BON1, ....BON9) 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.

12. PRECAUTIONS
Please pay attention to the followings when you use this TFT/LCD module with Back-light unit. 1)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 (C-MOS). 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.
