LP141E04
Liquid Crystal Display
Product Specification
1. General Description
The LP141E04-A1 is a Color Active Matrix Liquid Crystal Display with an integral Cold Cathode Fluorescent
Lamp(CCFL) 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 14.1 inches
diagonally measured active display area with SXGA+ resolution(1050 vertical by 1400 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 LP141E04-A1 has been designed to apply the interface method that enables low power, high speed,
low EMI.
The LP141E04-A1 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
LP141E04-A1 characteristics provide an excellent flat display for office automation products such as
Notebook PC.

2. Electrical Specifications
The LP141E04-A1 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 CCFL, is typically generated by an
inverter. The inverter is an external unit to the LCD.
