Liquid Crystal Display

Product Specification

1. General Description

The LP154WP2 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 LP154WP2 has been designed to apply the interface method that enables low power, high speed, low
EMI.

The LP154WP2 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
LP154WP2 characteristics provide an excellent flat display for office automation products such as Notebook
PC.

1. The specified current and power consumption are under the Vcc = 3.3V , 25℃, fv = 60Hz condition

whereas full black 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 variance of the voltage is ± 10%.

4. The typical operating current is for the typical surface luminance (LWH) in optical characteristics.
