LM215WF3

Liquid Crystal Display

Product Specification

1. General Description

LM215WF3 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 trans missive type display operating in the normally black mode. It has a 21.5inch diagonally
measured active display area with Full HD resolution (1920 vertical by 1080 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 8bit gray scale signal for each dot,
thus, presenting a palette of more than 16M colors. .
It has been designed to apply the 8bit 4Lane Display port interface.
It is intended to support displays where high brightness, super wide viewing angle,
high color saturation, and high color are important.

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.
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.

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 voltage at typical 60mA 100% duty current.

4. The specified power consumption is input LED string power consumption at typical 60mA 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 2¶C.

6. The LED power consumption shown above does not include loss of external driver.
The used LED BL current is the LED typical current.
String Power Consumption is calculated with P
BL Power Consumption is calculated with P

= VSx 60mA

7. LED operating DC Forward Current and Junction Temperature must not exceed LED Max Ratings.
