        1. General description
          LM220WE1-TLE1 is a Color Active Matrix Liquid Crystal Display with an integral Cold Cathode Fluorescent
         Lamp(CCFL) 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 22 inch diagonally measured active
         display area with WSXGA+ resolution (1050 vertical by 1680 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 LM220WE1-TLE1 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 CCFL/Backlight, is typically
         generated by an inverter. The inverter is an external unit to the LCDs.

           whereas mosaic pattern(8 x 6) is displayed and fV is the frame frequency.
        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
             is to be under 20MHz.

        Note :
          The design of the inverter must have specifications for the lamp in LCD Assembly.
          The performance of the Lamp in LCM, for example life time or brightness, is extremely influenced
          by the characteristics of the DC-AC inverter. So all the parameters of an inverter should be carefully
          designed so as not to produce too much leakage current from high-voltage output of the inverter.
          When you design or order the inverter, please make sure unwanted lighting caused by the mismatch of
          the lamp and the inverter (no lighting, flicker, etc) never occurs. When you confirm it, the LCD
