LP173WD1
Liquid Crystal Display
Product Specification
1. General Description
The LP173WD1 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 17.3 inches diagonally measured active display area with
WHD+ resolution(1600 horizontal by 900 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 LP173WD1 has been designed to apply the interface method that enables low power, high speed, low
EMI.
The LP173WD1 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
LP173WD1 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 flikering or relaibility 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 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 21mA.

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)
G WHITE =
Minimum(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.
