LM215WF4
Liquid Crystal Display
Product Specification
1. General description
LM215WF4-TLE2 is a Color Active Matrix Liquid Crystal Display with a 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 21.5 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. In
combination with the vertical arrangement of the sub-pixels, the LM215WF4-TLE2 characteristics
provide an excellent flat panel display for office automation products such as monitors.

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 an LED Driver. The LED driver is an external unit to the LCDs.
