LP140WHU
Liquid Crystal Display
Product Specification
1. General Description
The LP140WHU 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 14.0 inches diagonally measured active display area with HD
resolution (1366 horizontal by 768 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 LP140WHU has been designed to apply the interface method that enables low power, high
speed, low EMI. The LP140WHU 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 LP140WHU characteristics provide an excellent flat display for office automation products such
as Notebook PC.

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 following numerical formula.
For more information see FIG 2.
Maximum (L1,L2, ... L13) Maximum(L1,L2, ... L5)
G WHITE (13P) = G WHITE (5P) =
Minimum (L1,L2, ... L13) Minimum(L1,L2, ... L5)
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.

6. Reliability
Environment test condition
No. Test Item Conditions
1 High temperature storage test Ta= 60qC, 240h
2 Low temperature storage test Ta= -20qC, 240h
3 High temperature operation test Ta= 50qC, 50%RH, 240h
4 Low temperature operation test Ta= 0qC, 240h
5 Vibration test (non-operating) Sine wave, 5 ~ 150Hz, 1.5G, 0.37oct/min
3 axis, 30min/axis
6 Shock test (non-operating) - No functional or cosmetic defects following a shock
to all 6 sides delivering at least 180 G in a half sine
pulse no longer than 2 ms to the display module
- No functional defects following a shock delivering
at least 200 g in a half sine pulse no longer than 2
ms to each of 6 sides. Each of the 6 sides will be
shock tested with one each display, for a total of 6
displays
7 Altitude operating 0 ~ 10,000 feet (3,048m) 24Hr
storage / shipment 0 ~ 40,000 feet (12,192m) 24Hr
{ Result Evaluation Criteria }
There should be no change which might affect the practical display function when the display quality
test is conducted under normal operating condition.
