1. General Description

The LC420WX5 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 42.0 inch diagonally measured active display area with WXGA resolution (768 vertical by 1366 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 16.7M(true) colors. It has been designed to apply the 8-bit 1-port LVDS interface.

It is intended to support LCD TV, PCTV where high brightness, super wide viewing angle, high color gamut,high color depth and fast response time are important.

1. Electrical characteristics are determined after the unit has been ‘ON’and stable for approximately 120

minutes at 25?2?C. The specified current and power consumption are under the typical supply Input voltage 24V, it is total power consumption.

The ripple voltage of the power supply input voltage is under 0.4 Vp-p. LPL recommend Input Voltage is 24.0V ?5%.

2. Electrical characteristics are determined within 30 minutes at 25?2?C. The specified currents are under the typical supply Input voltage 24V.

4. The brightness of the lamp after lighted for 5minutes is defined as 100%.

T S is the time required for the brightness of the center of the lamp to be not less than 95% at typical current.The screen of LCD module may be partially dark by the time the brightness of lamp is stable after turn on.5. Specified Values are for a single lamp which is aligned horizontally.

The life time is determined as the time which luminance of the lamp is 50% compared to that of initial value at the typical/maximum lamp current(V BR-A=1.65V/3.3V) on condition of continuous operating at 25 ±2?C 6. The duration of rush current is about 15ms.

3-2. Interface Connections

This LCD module employs two kinds of interface connection, a 30-pin connector is used for the module electronics and Master 14-pin and Slave 12-pin connectors are used for the integral backlight system. 3-2-1. LCD Module

Optical characteristics are determined after the unit has been ‘ON’and stable in a dark environment at

25?2?C. The values are specified at an approximate distance 50cm from the LCD surface at a viewing angle of Φand θequal to 0 ?.

It is presented additional information concerning the measurement equipment and method in FIG. 1.

FIG. 1 Optical Characteristic Measurement Equipment and Method

Note :1. Contrast Ratio(CR) is defined mathematically as :

CR(Contrast Ratio) = Maximum CRn (n=1, 2, 3, 4, 5)DCR(Dynamic CR) = Maximum CRn (n=1, 2, 3, 4, 5)

Surface Luminance at position n with all white pixels

CRn =

Surface Luminance at position n with all black pixels

n = the Position number(1, 2, 3, 4, 5). For more information, see FIG 2.

2. Surface luminance are determined after the unit has been ‘ON’and 30min after lighting the backlight in a dark environment at 25?2?C. Surface luminance is the luminance value at center 1-point across the LCD surface 50cm from the surface with all pixels displaying white.For more information see the FIG. 2.

3. The variation in surface luminance , δWHITE is defined as :

δWHITE(5P) = Maximum(L on1,L on2, L on3, L on4, L on5) / Minimum(L on1,L on2, L on3, L on4, L on5)Where L on1to L on5are the luminance with all pixels displaying white at 5 locations . For more information, see the FIG. 2.

4. Response time is the time required for the display to transition from G(N) to G(M) (Rise Time, Tr R ) and from G(M) to G(N) (Decay Time, Tr D ). For additional information see the FIG. 3. (N

5. Viewing angle is the angle at which the contrast ratio is greater than 10. The angles are determined for the horizontal or x axis and the vertical or y axis with respect to the z axis which is normal to the LCD module surface. For more information, see the FIG. 4.

6. Gray scale specification

Gamma Value is approximately 2.2. For more information, see the Table 13.

B A : H / 4 mm B : V / 4 mm

H : 930.25 mm V : 523.01mm

@ H,V : Active Area

FIG.2 Measure Point for Luminance

Response time is defined as the following figure and shall be measured by switching the input signal for “Gray(N)”and “Gray(M)”.
