                                                 Product Specification

         1. General description
          LM185WH2-TLC1 is a Color Active Matrix Liquid Crystal Display with a Light Emitting Diode
         ( White LED) backlight system without LED Driver. 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 18.5 inch diagonally measured active display area with HD resolution (768 vertical by
         1366 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 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 LM185WH2-TLC1 characteristics provide an excellent
         flat panel display for office automation products such as monitors.

        3-1. Electrical characteristics
         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 a LED Driver. The LED Driver is an external unit to the LCDs.

        2. The current is specified at the maximum current pattern.
        3. Permissive power ripple should be measured under VCC=5.0V, 25 C, fV (frame frequency)=75Hz
             condition and At that time, we recommend the bandwidth configuration of oscilloscope

         LED driver design guide
               : 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.



         Notes :
         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 voltage at typical 110mA 100% duty current.
         4. The specified power consumption is input LED bar power consumption at typical 110mA 100%
            duty current.
         5. The life time 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 string current is the LED typical current.
            Typ Power Consumption is calculated with PBar = Vs(Typ.) x Is(Typ.) x Nstring
            Max Power Consumption is calculated with PBar = Vs(Max.) x Is(Typ) x Nstring

          Notes:
                   1. NC: No Connection.
                   2. All GND(ground) pins should be connected together and to Vss which should also
                      be connected to the LCD's metal frame.
                   3. All VLCD (power input) pins should be connected together.
                   4. Input Level of LVDS signal is based on the IEA 664 Standard.
                   5. PWM_OUT is a reference signal for inverter control.
                      This PWM signal is synchronized with vertical frequency.
                      Its frequency is 3 times of vertical frequency, and its duty ratio is 50%.
                      If the system don't use this pin, do not connect.

            kinds of defect phenomenon.

        Notes:
         1. LM185WH2-TLC1 is DE Only mode operation. The input of Hsync & Vsync signal does not
             have an effect on LCD normal operation.
         2. The performance of the electro-optical characteristics may be influenced by variance of the
            vertical refresh rates.
         3. Horizontal period should be even.

        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 avoid floating state of interface signal at invalid period.
           2. When the interface signal is invalid, be sure to pull down the power supply for
              LCD VLCD to 0V.
           3. 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 :It is measured at center point(1)
                                              Surface luminance with all white pixels
             Contrast ratio =            ---------------------------------------------------------
                                              Surface luminance with all black pixels

          2. Surface luminance is the luminance value at center 1 point(1) across
             the LCD surface 50cm from the surface with all pixels displaying white.
             For more information see FIG 8.

          3. The variation in surface luminance , G             WHITE   is defined as

                                          Minimum (P1,P2 .....P9)
                   G   WHITE   = --------------------------------------------- *100
                                          Maximum (P1,P2 .....P9)

          4. Response time is the time required for the display to transition from black to white
             (Decay Time, TrD) and from white to black (Rise Time, TrR)
            The sampling rate is 2,500 sample/sec. For additional information see FIG. 9.

            The response time is defined as the following figure and shall be measured by
            switching the input signal for each gray to gray.

          5. Viewing angle is the angle at which the contrast ratio is greater than 10 or 5. 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. 10 .
