1. General Description
The LM270WQ1 is a Color Active Matrix Liquid Crystal Display with 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 black mode. It has a 27inch diagonally measured active display area with QHD resolution (2560 vertical by 1440 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 10-bit gray scale signal for each dot, thus, presenting a palette of more than 1.07Billion colors with Advanced-FRC (Frame Rate Control). It has been designed to apply the 10-bit 4 port LVDS interface. 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, is typically generated by LED driver. The LED driver is an external unit to the LCDs.

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. 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. The specified current is input LED chip 100% duty current.
3. The specified voltage is input LED string and Bar voltage at typical 350 mA 100% duty current.
4. The specified power consumption is input LED string & bar power consumption at typical 350 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 2C.
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. String Power Consumption is calculated with PS = VS x Is Bar Power Consumption is calculated with PL = VBarx Is
7. LED operating DC Forward Current and Junction Temperature must not exceed LED Max Ratings at 25 r 2C.

Notes :
1. All GND(ground) pins should be connected together to the LCD module’s metal frame.
2. All V
LCD (power input) pins should be connected together.
3. All Input levels of LVDS signals are based on the EIA 644 Standard.
4. Specific pins(pin No. #2~#6) are used for internal data process of the LCD module. If not used, these pins are no connection.
5. LVDS pin (pin No. #24,25,40,41) are used for 10Bit(D) of the LCD module. If used for 8Bit(R), these pins are no connection.
6. Specific pin No. #44 is used for “No signal detection” of system signal interface. It should be GND for NSB(No Signal Black) during the system interface signal is not. If this pin is “H”, LCD Module displays AGP(Auto Generation Pattern).
