Liquid Crystal Display
Product Specification
1. General description
LM230WF5-TRA1 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 23.0 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 6-bit gray scale signal for each dot, thus, presenting a palette of more than 16,7M colors in case
of using 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 mini-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 LM230WF5-TRA1
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.

* 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.

Unit 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 and Bar voltage at typical 60 mA 100% duty current.
4. The specified power consumption is input LED bar power consumption at typical 60 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 r 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 = Vs(Max.) x Is(Typ) x Nstring
7. LED operating DC Forward Current and Junction Temperature must not exceed LED Max
Ratings at 25 r 2¶C.
