1. General Description
The LP141WX5 is a Color Active Matrix Liquid Crystal Display with an integral 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 WXGA
resolution(800 vertical by 1280 horizontal 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 LP141WX5 has been designed to apply the interface method that enables low power, high speed, low
EMI.
The LP141WX5 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
LP141WX5 characteristics provide an excellent flat display for office automation products such as Notebook
PC.

3. Electrical Specifications
3-1. Electrical Characteristics
The LP141WX5 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 LED, is typically generated by an
LED Driver. The LED Driver is an external unit to the LCD.

1. The specified current and power consumption are under the Vcc = 3.3V , 25℃, fv = 60Hz condition
whereas Mosaic 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 typical operating current is for the typical surface luminance (LWH) in optical characteristics
I
is the current of each LED’s string, LED backlight has 6 strings X 7 numbers on it.

4. The specified LED current and power consumption are under the Vled = 12.0V , 25℃, Dimming of Max
luminance whereas White pattern is displayed and fv is the frame frequency.
5. The life time is determined as the time at which brightness of LCD is 50% compare to that of minimum
value at Table 8. These LED backlight has 6 strings on it and the typical current of LED’s string is base
on typical current at Table 2.
