Liquid Crystal Display

Product Specification

1. General Description

The LM230W02 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 LM230W02 has been designed to apply the TMDS

TM

(Transition Minimized Differential Signaling) interface.

3. Electrical Specifications
3-1. Electrical Characteristics

The LM230W02 requires two power inputs. One input is employed to power the LCD electronics and to
drive the TFT array and liquid crystal. And the second input power for the CCFL / Backlight is to power
the inverter.

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.

5. The lamp must be turned on in condition of 0℃ temperature.
