LP171WU8
Liquid Crystal Display
Product Specification
1. General Description
The LP171WU8 is a Color Active Matrix Liquid Crystal Display with an integral RGB 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 black mode. This TFT-LCD has 17.1 inches diagonally measured active display
area with WUXGA resolution(1920 horizontal by 1200 vertical 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 10-bit gray scale signal for each dot, thus, presenting a palette of more
than 1.073G(True) colors.
The LP171WU8 has been designed to apply the interface method that enables low power, high speed, low
EMI. The LP171WU8 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
LP171WU8(SLB1) characteristics provide an excellent flat display for office automation products such as
Notebook PC.

3. Electrical Specifications
3-1. Electrical Characteristics
The LP171WU8(SLB1)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 internal unit to the LCD.

1. Contrast Ratio(CR) is defined mathematically as
Surface Luminance with all white pixels
Contrast Ratio =
Surface Luminance with all black pixels
2. Surface luminance is the 5point (1~5)average across the LCD surface 50cm from the surface
with all pixels displaying white Luminance (TBDnit). For more information see FIG 2.
3. Luminance % uniformity is measured for 13 point For more information see FIG 2.
WHITE = Maximum(LN1,LN2, ..... LN13) Minimum(LN1,LN2, ..... LN13)
4. Response time is the time required for the display to transition from white to black (rise time, TrR) and
from black to white(Decay Time, TrD). For additional information see FIG 3.
5. Viewing angle is the angle at which the contrast ratio is greater than 10. The angles are determined
for the horizontal or x axis and the vertical or y axis with respect to the z axis which is normal to the
LCD surface. For more information see FIG 4.
