Product Specification
1. General Description
LM240WU4 is a Color Active Matrix Liquid Crystal Display with an integral Cold Cathode Fluorescent
Lamp(CCFL) backlight 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. It has a 24inch diagonally measured
acti v e di s p la y ar e a w it h WUX G A re s o l ut io n (1 2 0 0 vertical by 19 2 0 horizo nt a l 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 10-bit gray scale signal for each dot,
thus, presenting a palette of more than 1.07B colors.
It has been designed to apply the 10Bit 2 port LVDS interface.
It is i nt e n d ed t o s u pp o rt d isp la y s w h er e hi g h b r ig htn es s , s u pe r wi d e v i ew i ng a ng l e,
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 CCFL, is typically generated by an inverter. The inverter is an
external unit to the LCD.

Note :
1. Permissive power ripple should be measured under V
=12.0V, 25 ± 2°C,fV=60Hz condition and At that
LCD
time, we recommend the bandwidth configuration of oscilloscope is to be under 20Mhz.
2. The specified current and power consumption are under the V

whereas mosaic pattern(8 x 6) is displayed and fVis the frame frequency.
3. The current is specified at the maximum current pattern.
4. The duration of rush current is about 2ms and rising time of power Input is 1ms(min.).

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. LGD recommend that PWM Freq. Is synchronized with three times harmonic of Vsync signal of system.
4. 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.
5. Electrical characteristics are determined after the unit has been ‘ON’ and stable for approximately
30min in a dark environment at 25 °C± 2°C.
6. In case of the difference in measured values due to the difference
of measuring device was found, correlated value will be used after discussions between both parties.
