LP101WX1

Liquid Crystal Display

Product Specification

1. General Description

The LP101WX1 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 10.1inches diagonally measured active display area with HD
resolution(1280 horizontal by 800 vertical pixel array). Each pixel is divided into Red, Green and Blue sub­pixels 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 LP101WX1 has been designed to apply the interface method that enables low power, high speed, low
EMI.

The LP101WX1 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
LP101WX1 characteristics provide an excellent flat display for office automation products such as Notebook
PC.

8. The operation of LED Driver below minimum dimming ratio may cause flickering or reliability issue.

9. This Spec. is not effective at 100% dimming ratio as an exception because it has DC level equivalent

to 0Hz. In spite of acceptable range as defined, the PWM Frequency should be fixed and stable for

more consistent brightness control at any specific level desired.

10. The life time is determined as the time at which brightness of LCD is 50% compare to that of minimum

value specified in table 7. under general user condition.
