1. Product Overview
Korean
General Description
TFT-LCD is made up of the lower plate glass with TFT, the upper plate glass with color filter, the middle
Liquid Crystal. TFT convey and control the signal and the Liquid Crystal control transmitted ray as
molecular structure different by admitted volt. And as the ray pass color filter, show up the wanted color
and picture.
The LP141WP1-TLA1 is 14.1 inches diagonally measured active display area with WXGA+ resolution(900
vertical by 1440 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 LP141WP1-TLA1 has been designed to apply the interface method that enables low power, high speed,
low EMI.
The LP141WP1-TLA1 is intended to support applications where thin thickness, low power are critical
factors and graphic display are important. In combination with the vertical arrangement of the sub-pixels,
the LP141WP1-TLA1 characteristics provide an excellent flat display for office automation products such
as Notebook PC.
