1. General description

LM220WE5-TLC1 is a Color Active Matrix Liquid Crystal Display 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 22 inch diagonally measured active
display area with WSXGA+ resolution (1050 vertical by 1680 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 LM220WE5-TLC1 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 CCFL/Backlight, is typically generated by an inverter. The
inverter is an external unit to the LCDs.

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

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

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 2ms 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.

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.
