   1. General Description
    The LP140WH4 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 LP140WH4 has been designed to apply the interface method that enables low power, high
   speed, low EMI. The LP140WH4 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 LP140WH4 characteristics provide an excellent flat display for office automation products such
   as Notebook PC.

The LP140WH4 requires two power inputs. The first logic is employed to power the LCD electronics and to
drive the TFT array and liquid crystal. The second backlight is the input about LED BL.with LED Driver.

    Max luminance and White pattern with the normal frame frequency operated(60Hz).
 8. The below figures are the measuring Vled condition                                   12.0V

 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 induce 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 brightness of LCD is 50% compare to that of minimum
     value specified in table 7. under general user condition.

 Note)
  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 be on pull-down condition on invalid status.
  4. LGD recommend the rising sequence of VLED after the Vcc and valid status of LVDS turn on.
4. Optical Specification
Optical characteristics are determined after the unit has been ‘ON’ and stable for approximately 30 minutes in
a dark environment at 25°C. The values specified are at an approximate distance 50cm from the LCD surface
at a viewing angle of Φ and Θ equal to 0°.
FIG. 1 presents additional information concerning the measurement equipment and method.

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.
 3. The variation in surface luminance , The panel total variation (δ 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)
             δ 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.

              to reduce possibility that results in vertical and/or horizontal line defect due to
              the conductive particles from screw surface.

9. PRECAUTIONS
Please pay attention to the followings when you use this TFT LCD module.
 (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.
9-5. STORAGE
When storing modules as spares for a long time, the following precautions are necessary.
(1) Store them in a dark place. Do not expose the module to sunlight 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.
