Liquid Crystal Display
Product Specification
1. General Description
The LP141X13(B1) 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 XGA resolution(768 vertical by 1024 horizonta l 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 LP141X13(B1) has been designed to apply the inte rface method that enables low power, high speed,
low EMI.
The LP141X13(B1) is intended to support applications where thin thickness, low power are c ritical factors
and graphic displays are important. In combination with the vertical arrangement of the sub-pixels, the
LP141X13(B1) characteristics provide an excellent flat display for office automation products such as
Notebook PC.

3. Electrical Specifications
3-1. Electrical Characteristics
The LP141X13(B1) requires two power inputs. One is employed to power the LCD e lectronics 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 t h e L CD.
