1. General Description
The LP154WX7 is a Color Active Matrix Liquid Crystal Display with an integral White 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 15.4 inches diagonally measured active display
area with WXGA resolution(800 vertical by 1280 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.
The LP154WX7 has been designed to apply the interface method that enables low power, high speed, low
EMI.
The LP154WX7 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
LP154WX7 characteristics provide an excellent flat display for office automation products such as Notebook
PC.

3. Electrical Specifications
3-1. Electrical Characteristics
The LP154WX7 requires two power inputs. One is employed to power the LCD electronics and to drive the
TFT array and liquid crystal. The second input which powers the White LED, is typically generated by an
LED Driver. The LED Driver is an external unit to the LCD.
