Abstract

The present invention discloses an LED display board which comprises a display unit matrix the long edge of a display unit of which deflect for an angle corresponding to the Y axis of a reference coordinate axis. The deflection angle can be a levorotation deflection angle and can also be a dextrorotation deflection angle. The better deflection angle range is from 30 to 60 DEG. The deflection can make the light diffusion direction of a display image generate a corresponding deflection angle, and thereby, different vision variation effects are generated. In addition, an LED display unit can also be coated with a light-absorbing material layer or a reflective material layer to make the LED display board have more various vision variation effects. The present invention can naturally generate the virtual stereo vision effect without changing a display control program.

Fig. 2 is the visual effect of LED display board shown in Figure 1, wherein, the highest display unit 11 regions of brightness are the image of required demonstration, visually be shown as the image of numeral 1, display unit 12 regions then are the contiguous later on inferior bright area that is irradiated to of light diffusion of the peripheral display unit of display image, and this zone constitutes the diffusion image of above-mentioned display image.

The defective of above-mentioned LED display board is: its diffusion image has only a kind of as shown in Figure 2, and does not have other vision change effect.

Summary of the invention

The purpose of this invention is to provide a kind of LED display board, this LED display board needn't be revised its display control program just can produce the virtual three-dimensional visual effect.

The objective of the invention is to realize by following technical measures: this LED display board comprises matrix of display elements, and the long limit of its display unit is with respect to reference coordinate axle Y-axis deflection one angle.Above-mentioned deflection can make the light dispersal direction of display image produce corresponding deflection angle, thereby produces different vision change effects.

Described deflection angle can be left-handed deflection, also can be dextrorotation deflection, and range of deflection angles is 30～60 ° preferably.Deflection angle difference, the visual effect that is produced are also different.

In order to make LED display board of the present invention have how different vision change effects, can also on led display unit, apply light absorbent layer or reflective material layer, the area of application can be the Zone Full of display unit side, also can be its regional area.

The present invention compared with prior art has the following advantages: since the long limit of display unit among the present invention with respect to reference coordinate axle Y-axis deflection one angle after, corresponding deflection angle also takes place in the light dispersal direction of display image, produce the oblique shade of required display image thus, therefore, need not to change display control program and just can produce stereoscopic visual effect naturally.When on led display unit, applying light absorbent layer or reflective material layer, also can further make the display image periphery form different diffusion images, thereby produce different visual effects.
