   1. General description
    LM240WU8 is a Color Active Matrix Liquid Crystal Display with an integral Light Emitting Diode (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. It has a 24 inch diagonally measured active display area with
   WUXGA resolution (1200 vertical by 1920 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 8-bit gray scale signal for each dot, thus, presenting a palette of more than 16,7M colors
   with Advanced-FRC(Frame Rate Control). It has been designed to apply the interface method that enables low
   power, high speed, low EMI. FPD Link or compatible must be used as a LVDS(Low Voltage Differential
   Signaling) chip. It is intended to support applications where thin thickness, wide viewing angle, low power are
   critical factors and graphic displays are important. In combination with the vertical arrangement of the sub-
   pixels, the LM240WU8's characteristics provide an excellent flat panel display for office automation products
   such as monitors.

    It requires two power inputs. One is employed to power the LCD electronics and to drive the
    TFT array and liquid crystal. The second input power for the LED Backlight, is typically
    generated by an LED Driver. The LED Driver is an external unit to the LCDs.

  LED driver design guide
       1) The design of the LED driver must have specifications for the LED in LCD Assembly.
          The performance of the LED in LCM, for example life time or brightness, is extremely influenced by
           the characteristics of the LED driver.
           So all the parameters of an LED driver should be carefully designed and output current should be
           Constant current control.
           Please control feedback current of each string individually to compensate the current variation
           among the strings of LEDs.
           When you design or order the LED driver, please make sure unwanted lighting caused by
           the mismatch of the LED and the LED driver (no lighting, flicker, etc) never occurs.
           When you confirm it, the LCD module should be operated in the same condition as installed in
           your instrument.
       2) LGD recommend that Dimming Control Signal ( PWM Signal) is synchronized with Frame Frequency
          for Wavy Noise Free.



  1. Specified values are for a single LED bar.
  2. The specified current is input LED chip 100% duty current.
  3. The specified voltage is input LED string and Bar voltage at typical 110 mA 100% duty current.
  4. The specified power consumption is input LED bar power consumption at typical 110 mA 100% duty current.
  5. The life is determined as the time at which luminance of the LED is 50% compared to that of initial
     value at the typical LED current on condition of continuous operating at 25 r 2 C.
  6. The LED bar power consumption shown above does not include loss of external driver.
     The used LED bar current is the LED typical current.
     Min Power Consumption is calculated with PBar = Vs(Min.) x Is(Typ.) x Nstring
     Max Power Consumption is calculated with PBar = Vbar(Max.) x Is(Typ) x Nstring
  7. LED operating DC Forward Current must not exceed LED Max Ratings at 25 2 C

             3. All VLCD (power input) pins should be connected together.
             4. Input Level of LVDS signal is based on the IEA 664 Standard.

    Note: Hsync period and Hsync width-active should be even number times of tCLK. If the value is odd number
          times of tCLK, display control signal can be asynchronous. In order to operate this LCM a Hsync,
           Vsyn, and DE(data enable) signals should be used.
          1. The performance of the electro-optical characteristics may be influenced by variance of the vertical
               refresh rates.
          2. Vsync and Hsync should be keep the above specification.
          3. Hsync Period, Hsync Width, and Horizontal Back Porch should be any times of of character
              number(8).
          4. The polarity of Hsync, Vsync is not restricted.

      3-6. Color input data reference
    The brightness of each primary color (red,green and blue) is based on the 8bit 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.

    Notes :
      1. Please VLCD power on only after connecting interface cable to LCD.
      2. Please avoid floating state of interface signal at invalid period.
      3. When the interface signal is invalid, be sure to pull down the power supply for
         LCD VLCD to 0V.
      4. Lamp power must be turn on after power supply for LCD an interface signal are valid.

    Notes 1. Contrast Ratio(CR) is defined mathematically as : (By PR880)
                                                  Surface Luminance with all white pixels
                            Contrast Ratio
                                                  Surface Luminance with all black pixels
                It is measured at center point(Location P1)

           2. Surface luminance(LWH)is luminance value at 5 points average across the LCD surface 50cm from
              the surface with all pixels displaying white. For more information see FIG 7. (By PR880)
               LWH = = Average[ Lon1,Lon2,Lon3,Lon4,Lon5]

           3. The variation in surface luminance , G WHITE is defined as : (By PR880)

                                      Minimum(L P1 , L P2 , }.. L P9 )
                            GWHITE                                       u 100
                                      Maximum (L P1 , L P2 , .... L P9 )

                Where L1 to L9 are the luminance with all pixels displaying white at 9 locations.
                For more information see FIG 8.

           4. Gray to gray response time is the time required for the display to transition from gray to gray. For
              additional information see Table 10. (By RD80S)

           5. Color shift is the angle at which the average color difference for all Macbeth is lower than 0.02.
              For more information see FIG 9. (By EZ Contrast)
