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 r
esolution(768 vertical by 1366 horizontal pixel array). Each pixel is divided into Red, Green and Blue sub-pix
els or dots which are arranged in vertical stripes. Gray scale or the brightness of the sub-pixel color is deter
mined 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 LP140W
H1 characteristics provide an excellent flat display for office automation products such as Notebook PC.

2. 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.

3. This Spec. is the max load condition for the cable impedance designing.

4. The below figures are the measuring Vcc condition and the Vcc control block LGD used.
The Vcc condition is same the minimum of T1 at Power on sequence.

5. This impedance value is needed to proper display and measured form LVDS Tx to the mating connector.

6. The measuring position is the connector of LCM and the test conditions are under 25℃.

7. The current and power consumption with LED Driver are under the Vled = 12.0V , 25℃, Dimming of
Max luminance whereas White pattern is displayed and fv is the frame frequency.

8. The below figures are the measuring Vled condition
and the Vled control block LGD used.
VLED control block is same with Vcc control block.

9. The operation of LED Driver below minimum dimming ratio may cause flickering or reliability issue.

10. If Jitter of PWM is bigger than maximum. It may cause flickering.

11. 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.
12 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 18mA.

3-6. Color Input Data Reference

The brightness of each primary color (red,green and blue) is based on the 6-bit gray scale data input for the
color ; the higher the binary input, the brighter the color. The table below provides a reference for color

1. Do not insert the mating cable when system turn on.

2. Valid Data have to meet “3-3. LVDS Signal Timing Specifications”

3. LVDS, LED_EN and PWM need to pull-down condition on invalid status.

4. LGD recommend the rising sequence of VLED after the Vcc and valid status of LVDS turn on.

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 (

at each test position 1 through 13 and then defined as followed numerical formula.

For more information see FIG 2.

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 than HB
pencil lead. And please do not rub with dust clothes with chemical treatment.
Do not touch the surface of polarizer for bare hand or greasy cloth.(Some cosmetics are detrimental
to the polarizer.)
(7) When the surface becomes dusty, please wipe gently with absorbent cotton or other soft materials like

chamois soaks with petroleum benzene. Normal-hexane is recommended for cleaning the adhesives

used to attach front / rear polarizers. Do not use acetone, toluene and alcohol because they cause

chemical damage to the polarizer.

(8) Wipe off saliva or water drops as soon as possible. Their long time contact with polarizer causes

deformations and color fading.

(9) Do not open the case because inside circuits do not have sufficient strength.

9-2. OPERATING PRECAUTIONS

(1) The spike noise causes the mis-operation of circuits. It should be lower than following voltage :

V=± 200mV(Over and under shoot voltage)

(2) Response time depends on the temperature.(In lower temperature, it becomes longer.)
(3) Brightness depends on the temperature. (In lower temperature, it becomes lower.)
And in lower temperature, response time(required time that brightness is stable after turned on) becomes
longer.
(4) Be careful for condensation at sudden temperature change. Condensation makes damage to polarizer or

electrical contacted parts. And after fading condensation, smear or spot will occur.

(5) When fixed patterns are displayed for a long time, remnant image is likely to occur.
(6) Module has high frequency circuits. Sufficient suppression to the electromagnetic interference shall be

done by system manufacturers. Grounding and shielding methods may be important to minimized the

interference.

Since a module is composed of electronic circuits, it is not strong to electrostatic discharge. Make certain that
treatment persons are connected to ground through wrist band etc. And don’t touch interface pin directly.

9-3. ELECTROSTATIC DISCHARGE CONTROL

Strong light exposure causes degradation of polarizer and color filter.

9-4. PRECAUTIONS FOR STRONG LIGHT EXPOSURE

9-5. STORAGE

(1) When the protection film is peeled off, static electricity is generated between the film and polarizer.
This should be peeled off slowly and carefully by people who are electrically grounded and with well
ion-blown equipment or in such a condition, etc.
(2) The protection film is attached to the polarizer with a small amount of glue. If some stress is applied
to rub the protection film against the polarizer during the time you peel off the film, the glue is apt to
remain on the polarizer.
Please carefully peel off the protection film without rubbing it against the polarizer.
(3) When the module with protection film attached is stored for a long time, sometimes there remains a
very small amount of glue still on the polarizer after the protection film is peeled off.
(4) You can remove the glue easily. When the glue remains on the polarizer surface or its vestige is
recognized, please wipe them off with absorbent cotton waste or other soft material like chamois
soaked with normal-hexane.

9-6. HANDLING PRECAUTIONS FOR PROTECTION FILM

When storing modules as spares for a long time, the following precautions are necessary.

(1) Store them i n a dark place. Do not expose the module to sunli gh t or fluorescent light . Keep the

temperature between 5C and 35C at normal humidity.
(2) The polarizer surface should not come in contact with any other object.
It is recommended that they be stored in the container in which they were shipped.
