         1. General Description
          The LP140WH2 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 LP140WH2 has been designed to apply the interface method that enables low power, high
         speed, low EMI. The LP140WH2 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 LP140WH2 characteristics provide an excellent flat display for office automation products such
         as Notebook PC.

         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.

         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
         versus data input.

            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.

        Optical characteristics are determined after the unit has been `ON' and stable for approximately 20 minutes in
        a dark environment at 25qC. The values specified are at an approximate distance 50cm from the LCD surface
        at a viewing angle of ) and 4 equal to 0q.

       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, ... L5)
              G WHITE_5P =
                                            Minimum(L1,L2, ... L5)


                                            Maximum(L1,L2, ... L13)
              G WHITE_13P =
                                            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.
