                                                Product Specification

    1. General Description
   LM270WF5-SSA1 is a Color Active Matrix Liquid Crystal Display with an integral Light Emitting Diode (White 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 27 inch diagonally measured active display area with Full
  HD resolution (1080 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. It is intended to support displays where high brightness, super wide viewing angle,
  high color saturation, and high color are important.

    3. Electrical Specifications

     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.

    Note :
    1. Permissive power ripple should be measured under VLCD =5.0V, 25 C, fV(frame frequency)=MAX
        condition and At that time, we recommend the bandwidth configuration of oscilloscope is to be under
        20Mhz. See the next page.

     2. The specified current and power consumption are under the V LCD=5.0V, 25 2 C,fV=60Hz condition
         whereas Typical Power Pattern [Mosaic] shown in the [ Figure 3 ] is displayed.

     3. The current is specified at the maximum current pattern.



     4. Maximum Condition of Inrush current :
        The duration of rush current is about 5ms and rising time of power Input is 500us r 20%.(min.).
