Product Specification
1. General Description
LM215WF3 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 black mode. It has a 21.5 inch diagonally
measured active display area with FHD resolution (1080 vertical by 1920horizontal 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 A-FRC (Advanced Frame Rate Control).
It has been designed to apply the 8Bit 2 port LVDS interface.
It is in t e nd e d to s u p po r t d i s p l ay s w h e r e h ig h b r i g ht n e s s, s u p e r wi de vi ew i n g a n gl e,
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 an inverter. The inverter is an
external unit to the LCDs.

Unit Notes
LED driver design guide
1) 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.
2) LGD recommend that Dimming Control Signal ( PWM Signal) should be synchronized
with Frame Frequency for Wavy Noise Free.
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 and Bar voltage at typical 110 mA 100% duty current.
4. The specified power consumption is input LED bar power consumption at typical 110 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 2°C.
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.
Min Power Consumption is calculated with PBar = Vs(Min.) x Is(Typ.) x Nstring
Max Power Consumption is calculated with PBar = Vbar(Max.) x Is(Typ) x Nstring

Note: 1. All GND(ground) pins should be connected together and to Vss which should also be connected to
the LCD‟s metal frame.
2. All VLCD (power input) pins should be connected together.
3. Input Level of LVDS signal is based on the IEA 664 Standard.
4. PWM_OUT signal controls the burst frequency of a inverter.
This signal is synchronized with vertical frequency.
It‟s frequency is 3 times of vertical frequency, and it‟s duty ratio is 50%.
If you don‟t use this pin, it is no connection.
