    1. General Description
    The LC320EUN is a Color Active Matrix Liquid Crystal Display with an integral Light Emitting Diode (LED)
    b ac k l i g ht s ys t em . T he m a t r i x em p l o ys a - S i T h i n F i lm T r an s is t or a s t he a c t i v e e l em en t .
    It is a transmissive display type which is operating in the normally black mode. It has a 31.55 inch diagonally
    measured active display area with WUXGA resolution (1080 vertical by 1920 horizontal pixel array).
    Each pixel is divided into Red, Green and Blue sub-pixels or dots which are arrayed in vertical stripes.
    Gray scale or the luminance of the sub-pixel color is determined with a 8-bit gray scale signal for each dot.
    Therefore, it can present a palette of more than 16.7Million colors.
    It has been designed to apply the 8-bit 2-port LVDS interface.
    It is intended to support LCD TV, PCTV where high brightness, super wide viewing angle, high color gamut,
    high color depth and fast response time are important.

                                                                      Mini-LVDS(RGB)

    Note1. Ambient temperature condition (Ta = 25 r 2 C )
        2. Temperature and relative humidity range are shown in the figure below.
            Wet bulb temperature should be Max 39 C, and no condensation of water.
        3. Gravity mura can be guaranteed below 40 C condition.
        4. The maximum operating temperatures is based on the test condition that the surface temperature
           of display area is less than or equal to 68 C with LCD module alone in a temperature controlled chamber.
           Thermal management should be considered in final product design to prevent the surface temperature of
           display area from being over 68 . The range of operating temperature may be degraded in case of
           improper thermal management in final product design.

     Notes :
      1. Electrical characteristics are determined after the unit has been `ON' and stable for approximately 60
         minutes at 25 2 C. The specified current and power consumption are under the typical supply Input voltage
         24V and VBR (ExtVBR-B : 100%), it is total power consumption.
      2. The life time (MTTF) is determined as the time which luminance of the LED is 50% compared to that of initial
         value at the typical LED current (ExtVBR-B :100%) on condition of continuous operating in LCM state at
         25 2 C.
      3. LGD recommend that the PWM freq. is synchronized with One time harmonic of V_sync signal of system.
         Though PWM frequency is over 120Hz (max 252Hz), function of LED Driver is not affected.
      4. The duration of rush current is about 200ms. This duration is applied to LED on time.
      5. Even though inrush current is over the specified value, there is no problem if I2T spec of fuse is satisfied
      6. ExtVBR-B signal have to input available duty range and sequence.
        After Driver ON signal is applied, ExtVBR-B should be sustained from 5% to 100% more than 500ms.
             After that, ExtVBR-B 1% and 100% is possible
        For more information, please see 3-6-2. Sequence for LED Driver.

    Note: 1. The input of HSYNC & VSYNC signal does not have an effect on normal operation (DE Only Mode).
             If you use spread spectrum of EMI, add some additional clock to minimum value for clock margin.

          2. The performance of the electro-optical characteristics may be influenced by variance of the vertical
             refresh rate and the horizontal frequency

             Timing should be set based on clock frequency.

    3-5. Color Data Reference

     The brightness of each primary color(red,green,blue) is based on the 8-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. Please avoid floating state of interface signal at invalid period.
          2. When the power supply for LCD (VLCD) is off, be sure to pull down the valid and invalid data to 0V.
          3. The T3 / T4 is recommended value, the case when failed to meet a minimum specification,
             abnormal display would be shown. There is no reliability problem.
          4. If the on time of signals(Interface signal and user control signals) precedes the on time of Power(VLCD),
             it will be happened abnormal display. When T6 is NC status, T6 doesn't need to be measured.
          5. T5 should be measured after the Module has been fully discharged between power off and on
             period.
          6. It is recommendation specification that T8 has to be 100ms as a minimum value.

    Note : 1. Contrast Ratio(CR) is defined mathematically as :
                                  Surface Luminance with all white pixels
              Contrast Ratio =
                                  Surface Luminance with all black pixels
              It is measured at 5 point
           2. Surface luminance are determined after the unit has been `ON' and 1 Hour after lighting the
              backlight in a dark environment at 25 2 C. Surface luminance is the luminance value at n = the
              Position number(1, 2, 3, 4, 5) across the LCD surface 50cm from the surface with all pixels
              displaying white. For more information see the FIG. 2.
           3. The variation in surface luminance , G WHITE is defined as :

                  G WHITE(5P) = Maximum(Lon1,Lon2, Lon3, Lon4, Lon5) / Minimum(Lon1,Lon2, Lon3, Lon4, Lon5)
              Where Lon1 to Lon5 are the luminance with all pixels displaying white at 5 locations .
              For more information, see the FIG. 2.
           4. Response time is the time required for the display to transit from G(N) to G(M) (Rise Time, TrR)
              and from G(M) to G(N) (Decay Time, TrD). For additional information see the FIG. 3. (N
