LP154WP3
Liquid Crystal Display
Product Specification
1. General Description
The LP154WP3 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 15.4 inches diagonally measured active display area with
WXGA+ resolution(1440 horizontal by 900 vertical 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 LP154WP3 has been designed to apply the interface method that enables low power, high speed, low
EMI.
The LP154WP3 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
LP154WP3 characteristics provide an excellent flat display for office automation products such as Notebook
PC.

1. Contrast Ratio(CR) is defined mathematically as
Surface Luminance with all white pixels
Contrast Ratio =
Surface Luminance with all black pixels
2. 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 FIG 3.
3. 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. For more information see FIG 4.
