LP173WF1
Liquid Crystal Display
Product Specification


1. General Description
The LP173WF1 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 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 LP173WF1 has been designed to apply the interface method that enables low power, high
speed, low EMI. The LP173WF1 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 LP173WF1 characteristics provide an excellent flat display for office automation products such as
Notebook PC.

10. 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.
11. 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 22mA.

Note)
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.

LP173WF1
Liquid Crystal Display
Product Specification


LGD Proposal for system cover design.(Appendix)

Gap check for securing the enough gap between LCM
1
and System cover.

Max Thickness




Sponge


LCM Reflector Side



System Cover



A Boundary Line


1.Rear side of LCM is sensitive against external stress,and previous check
about interference is highly needed.
Notes 2.In case there is something from system cover comes into the boundary
above,mechanical interference may cause the FOS defects.
(Eg:Ripple,White spot..)

2 Check if antenna cable is sufficiently apart from T-CON of LCD Module.




NO GOOD GOOD


Notes 1.If system antenna is overlapped with T-CON,it might be cause the noise.

Product Specification

LGD Proposal for system cover design.
Gap check for securing enough gap between LCM
3
and System hinge.




LCM Reflector Side




COF
(D-IC)



Hinge
Side Mount Screw Hole (4ea)
GAP:Min2.0mm ("I" TYPE) ("L" TYPE)

1. At least 2.0mm gap is required to secure from any damage
during shock test.
Notes
2. "L" type hinge is more recommended than "I" type to get better
performance for shock test.

4 Checking the path of the System wire.




#3 #2
#1
Ok Bad Good
1. It is required to handle COF area carefully .
2. Good : Wire path does not overlap with LCM
Notes OK : Wire path is located between COFs.
BAD : Wire path overlapped with COF area.
Flat type cable is highly recommended if cable should be located on bad case
