LM230WF3
Liquid Crystal Display
Product Specification
1. General Description
LM230WF3 is a Color Active Matrix Liquid Crystal Display with a 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 black mode. It has a 23 inch |
diagonally measured |
active display area with FHD resolution (1080 vertical by 1920horizontal 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 A-FRC (Advanced Frame Rate Control).
It has been designed to apply the 8Bit 2 port LVDS interface.
It is intended to support displays where high brightness, super wide viewing angle, high color saturation, and high color are important.

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

Note :
1.Permissive power ripple should be measured under VLCD =5.0V, 25°C, fV(frame frequency)=MAX condition and At that time, we recommend the bandwidth configuration of oscilloscope is to be under 20Mhz. See the next page.
2.The specified current and power consumption are under the VLCD=5.0V, 25± 2°C,fV=60Hz condition whereas Typical Power Pattern [Mosaic] shown in the [ Figure 3 ] is displayed.
3.The current is specified at the maximum current pattern.
4.Maximum Condition of Inrush current :
The duration of rush current is about 5ms and rising time of power Input is 500us ± 20%.(min.).

Notes) The LED Bar consists of 32 LED packages, 2 strings (parallel) x 16 packages (serial)
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.The specified values are for a single LED bar.
2.The specified current is defined as the input current for a single LED string with 100% duty cycle.
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 PBar = Vs(Typ.) x Is(Typ.) x No. of strings. The maximum power consumption is calculated as PBar = Vs(Max.) x Is(Typ.) x No. of strings.
5.LED operating conditions are must not exceed Max. ratings.
