LP171WP9
Liquid Crystal Display
Product Specification
1. General Description
The LP171WP9WF1 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 17.1 inches diagonally measured active display
area with FHD resolution(1920 horizontal by 1080 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 6-bit gray scale signal for each dot, thus, presenting a palette of more than
262,144 colors.
The LP171WP9 has been designed to apply the interface method that enables low power, high speed, low
EMI.
The LP171WP9 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
LP171WP9 characteristics provide an excellent flat display for office automation products such as Notebook
PC.

1. The specified Icc 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 specified LED current and power consumption are under the Vled = 12.0V , 25 , Dimming of Max

4. The operation of LED Driver below minimum dimming ratio may cause flickering or reliability issue.
5. 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.
6. The life time is determined as the time at which the typical brightness of LCD is 50% compare to that of
initial value at the typical LED current. These LED backlight has 6 strings on it and the typical current of
LED's string is base on TBDmA.

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 average of 5 point across the LCD surface 50cm from the surface with
all pixels displaying white. For more information see FIG 1.
LWH = Average(L1,L2, ... L5)
3. The variation in surface luminance , The panel total variation (G WHITE) is determined by measuring LN
at each test position 1 through 13 and then defined as followed numerical formula.
For more information see FIG 2.
Maximum(L1,L2, ... L13) - Minimum(L1,L2, ... L13)
G WHITE( = * 100(%)
Maximum(L1,L2, ... L13)
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.
