1. General Description

LM270WF5-SLA1 is a Color Active Matrix Liquid Crystal Display with an integral Light Emitting Diode (White 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 27 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 sub­pixels 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

graphic displays are important. It is intended to support displays where high brightness, super wide viewing angle,
high color saturation, and high color are important.

ectrical 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 a LED Driver.
The LED Driver is an external unit to the LCDs.

Notes) The LED Bar consists of 42 LED packages, 3 strings (parallel) x 14 packages (serial)

ver 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

.
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.

Unit Notes

1. The specified values are for a single LED bar.

3. The LED life time is defined as the time when brightness of LED packages become 50% or less

than the initial value under the conditions at Ta = 25 ± 2°C and LED string current is typical value.

4. The power consumption shown above does not include loss of external driver.
The typical power consumption is calculated as P
The maximum power consumption is calculated as P

Bar = Vs(Typ.) x Is(Typ.) x No. of strings.

Bar = Vs(Max.) x Is(Typ.) x No. of strings.

5. LED operating conditions are must not exceed Max. ratings.

Note: 1. All GND(ground) pins should be connected together and to Vss which should also be connected to

the LCD’s metal frame.

. 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.
