Product Specification
1. General Description
The LM230WU3 LCD is a Color Active Matrix Liquid Crystal Display with an integral Cold Cathode Fluorescent
Lamp(CCFL) back light system. The matrix employs a-Si Thin Film Transistor as the active element. It is a
transmissive type display operating in the normally black mode. This TFT-LCD has a 23.0 inch diagonally
measured active display area with WUXGA resolution(1200 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 luminance of the sub-pixel color is determined with a 8-bit gray scale signal for each dot, thus, presenting
a palette of more than 16,777,216 colors.
The LM230WU3 has been designed to apply the 2 port LVDS interface.

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, is typically generated by an inverter. The inverter is an
external unit to the LCDs.

Notes :
1. The input voltage ripple is limited below 400mVp-p.
2.The specified current and power consumption are under the typical supply Input voltage, 24V.
3.The life is determined as the time at which luminance of the lamp is 50% compared to that of initial
value at the typical lamp current on condition of continuous operating at 25 ± 2°C.
4. Electrical characteristics are determined after the unit has been ‘ON’ and stable for approximately
30min in a dark environment at 25 °C± 2°C.
