Product Specification

1. General description

LM215WF4-TLE9 is a Color Active Matrix Liquid Crystal Display with an integral 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-TLE9 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.

Note :

1. The specified current and power consumption are

under the VLCD=5.0V, 25 ± 2°C,fV=60Hz condition

whereas mosaic pattern(8 x 6) is displayed and fVis the frame frequency.

2. The current is specified at the maximum current pattern and L80.

3. Permissive power ripple should be measured under VCC=5.0V, 25°C, fV (frame frequency)=75Hz

condition and At that time, we recommend the bandwidth configuration of oscilloscope
is to be under 20MHz.

4. The duration of rush current is about 5ms and rising time of power Input is 500us ± 20%.

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.

Notes :

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 110mA 100% duty current.

4. The specified power consumption is input LED bar power consumption
at typical 110mA 100% duty current.

5. The life time 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 string current is the LED typical current.
Typ Power Consumption is calculated with PBar = Vs(Typ.) x Is(Typ.) x Nstring
Max Power Consumption is calculated with PBar = Vs(Max.) x Is(Typ) x Nstring
