LP133WX3
Liquid Crystal Display
Product Specification
1. General Description
The LP133WX3 is a Color Active Matrix Liquid Crystal Display with an integral LED backlight 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 13.3 inches diagonally measured active display area with WXGA
resolution(1280 horizontal by 800 vertical 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 palette of more than 262,144 colors.
The LP133WX3 has been designed to apply the interface method that enables low power, high speed, low
EMI.
The LP133WX3 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 LP133WX3
characteristics provide an excellent flat display for office automation products such as Notebook PC.

Note)
1. The specified current and power consumption are under the Vcc = 3.3V , 25℃, fv = 60.2Hz condition
whereas Mosaic pattern is displayed and fv is the frame frequency.
2. This impedance value is needed to proper display and measured form LVDS Tx to the mating connector.
3. The typical operating current is for the typical surface luminance (LWH) in optical characteristics.
4. The LED power consumption shown above does not include power of external LED driver circuit
for typical current condition.
5. 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.
