Liquid Crystal Display

Product Specification

1. General Description

LM215WF4 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 White mode. It has a 215 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 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 an LED driver. The
driver is an external unit to the LCDs.

Note :

1. Permissive power ripple should be measured under VCC=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

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.

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

7. LED operating DC Forward Current and Junction Temperature must not exceed LED Max Ratings at 25  2°C.
