LP140WH1
Liquid Crystal Display
Product Specification
1. General Description
The LP140WH1 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(768 vertical by 1366 horizontal 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 LP140WH1 has been designed to apply the interface method that enables low power, high speed, low
EMI.
The LP140WH1 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
LP140WH1 characteristics provide an excellent flat display for office automation products such as Notebook
PC. EEPROM Block

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.

9. PRECAUTIONS
Please pay attention to the followings when you use this TFT LCD module.
9-1. MOUNTING PRECAUTIONS
(1) You must mount a module using holes arranged in four corners or four sides.
(2) You should consider the mounting structure so that uneven force (ex. Twisted stress) is not applied to the
module. And the case on which a module is mounted should have sufficient strength so that external
force is not transmitted directly to the module.
(3) Please attach the surface transparent protective plate to the surface in order to protect the polarizer.
Transparent protective plate should have sufficient strength in order to the resist external force.
(4) You should adopt radiation structure to satisfy the temperature specification.
(5) Acetic acid type and chlorine type materials for the cover case are not desirable because the former
generates corrosive gas of attacking the polarizer at high temperature and the latter causes circuit break
by electro-chemical reaction.
(6) Do not touch, push or rub the exposed polarizers with glass, tweezers or anything harder tha
