1. General Description

The LC320WUN is a Color Active Matrix Liquid Crystal Display with an integral External Cathode Fluorescent Lamp(EEFL) backlight system. The matrix employs a-Si Thin Film Transistor as the active element. It is a transmissive display type which is operating in the normally black mode. It has a 31.55 inch diagonally measured active display area with WUXGA resolution (1080 vertical by 1920 horizontal pixel array). Each pixel is divided into Red, Green and Blue sub-pixels or dots which are arrayed in vertical stripes. Gray scale or the luminance of the sub-pixel color is determined with a 10-bit gray scale signal for each dot. Therefore, it can present a palette of more than 1.06B(true) colors.

It has been designed to apply the 10-bit 2-port LVDS interface.

It is intended to support LCD TV, PCTV where high brightness, super wide viewing angle, high color gamut,

Note : 1. Please avoid floating state of interface signal at invalid period.

2. When the interface signal is invalid, be sure to pull down the power supply V LCD to 0V.

3. The T3/T4 is recommended value, the case when failed to meet a minimum specification, abnormal display would be shown. There is no reliability problem.

4. If the on time of signals(Interface signal and Option signals) precedes the on time of Power(V LCD ),check the LCD logic Power(Vcc) is under 0.8V, otherwise it will be happened abnormal display.

FIG. 1 Optical Characteristic Measurement Equipment and Method

Optical characteristics are determined after the unit has been ‘ON’and stable in a dark environment at 25±2°C. The values specified are at an approximate distance 50cm from the LCD surface at a viewing angle of Φand θequal to 0 °.

FIG. 1 shows additional information concerning the measurement equipment and method.

4. Optical Specification

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

CR(Contrast Ratio) = 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.※DCR Application : Refer to Appendix V

2. Surface luminance are determined after the unit has been ‘ON’and 1hour 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 12.
