LC320WXN
Product Specification
1. General Description
The LC320WXN is a Color Active Matrix Liquid Crystal Display with an integral External Electrode Fluorescent
Lamp(EEFL) 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 31.51 inch diagonally measured
active d ispla y area with WXGA reso lution (768 ver tica l by 1366 ho r izontal pixel array).
Each pixel is divided into Red, Green and Blue sub-pixels or dots which are arranged in Horizontal 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.

Notes :
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
24Vand VBR (VBR-A : 1.65V & ExtVBR-B : 100%), it is total power consumption.
The ripple voltage of the power supply input voltage is under 0.5 Vp-p. LGD 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.
3. The brightness of the lamp after lighted for 5minutes is defined as 100%.
TS 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.
4. 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 lamp current (VBR-A : 1.65V & ExtVBR-B :100%), on condition of continuous operating at 25 2 C
5. LGD recommend that the PWM freq. is synchronized with Two times harmonic of Vsync signal of system.
6. The duration of rush current is about 10ms.

Note :
1. The input of HSYNC & VSYNC signal does not have an effect on normal operation(DE Only Mode).
If you use spread spectrum of EMI, add some additional clock to minimum value for clock margin.
2. The performance of the electro-optical characteristics may be influenced by variance of the vertical
refresh rate and the horizontal frequency
3. Timing should be set based on clock frequency.

Product Specification
Notes :1. Contrast Ratio(CR) is defined mathematically as :
Surface Luminance at all white pixels
CR =
Surface Luminance at all black pixels
It is measured at center 1-point.
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 , G WHITE is defined as :
G WHITE(5P) = Maximum(Lon1,Lon2, Lon3, Lon4, Lon5) / Minimum(Lon1,Lon2, Lon3, Lon4, Lon5)
Where Lon1 to Lon5 are 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, TrR)
and from G(M) to G(N) (Decay Time, TrD). For additional information see the FIG. 3. (N G to G Spec stands for average value of all measured points.
5. Gray to Gray Response time uniformity is Reference data. Please see Appendix XI.
6. 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.
7. Gray scale specification
Gamma Value is approximately 2.2. For more information, see the Table 11.

9. Precautions
Please pay attention to the followings when you use this TFT LCD module.
9-1. Mounting Precautions
(1)You must mount a module using specified mounting holes (Details refer to the drawings).
(2) You should consider the mounting structure so that uneven force (ex. Twisted stress) is not applied to the
module. And the case on which a module is mounted should have sufficient strength so that external
force is not transmitted directly to the module.
(3) Please attach the surface transparent protective plate to the surface in order to protect the polarizer.
Transparent protective plate should have sufficient strength in order to the resist external force.
(4) You should adopt radiation structure to satis
