Abstract
The LED display plate comprises the matrix of display units, whose long edge is deflected an angle in 30-60 degrees either right or left deflexion related to the reference coordinate axis. The said deflexion makes the light direction of diffusion generate the relevant deflextion angles so as to create the effect of vision fluctuation. Moreover, light-absorbing materials or reflective materials can be coated on the LED display units, making the LED display plate possess various effects of vision fluctuation. The invention generates virtual 3D vision effect without need of changing the display control program.
Description
Affiliated technical field
The present invention relates to a kind of LED display board, particularly relate to a kind of LED display board that produces the virtual three-dimensional visual effect.
Background technology
Existing LED display board is formed display matrix by the LED unit of arranging in length and breadth as shown in Figure 1, and each LED unit 10 has two long limits and two minor faces, is parallel to reference coordinate axle Y-axis and X-axis (not shown) respectively.When the LED unit was luminous, above-mentioned long limit and minor face all can have light to diffuse out, for the ease of explaining, the present invention only describes with the light diffusion of growing the limit, its dispersal direction a little less than the diffusion relatively of the light of minor face, is omitted at this shown in the lateral arrows among the figure.
The briliancy of led display unit height is represented with the spot density size that is marked on the display unit among Fig. 1, and the spot close person of healing represents that briliancy is higher, and vice versa; In addition, the briliancy of display unit also can adopt numeral 1,2,3,4 and 5 to represent that the briliancy method for expressing of other accompanying drawing is also identical therewith in this instructions from high to low successively.As shown in Figure 1, six LED unit 11 that are arranged in display board central authorities are the display board brightest area in when work, show the image information of required expression, and these six led display units are triplex row two row to be arranged, and visually is the image of numeral 1.
The light diffusion on 11 long limits, LED unit is penetrated along about X-axis shown in arrow among the figure, and the brightness that demonstrates behind three the LED unit in three LED unit 12, its left side and the right, the 12 reception light is a little less than the brightness of display unit 11.
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.

Embodiment
Fig. 3 is the synoptic diagram of first embodiment of the present invention, and the led display unit 10 among this embodiment is 5 row, 6 row to be arranged, and the long limit of each display unit is with respect to 45 ° of reference coordinate axle Y-axis deflections to the right.Be positioned at the brightest area that shows when central 3 row, 2 row display units 11 are worked for display board among the figure, show required image, visually be shown as the image of numeral 1.Because the long limit of each display unit is with respect to the deflection of reference coordinate axle Y-axis, the diffusion light on the long limit of the display unit 11 of brightest area is shown in the arrow among Fig. 3, promptly identical with above-mentioned deflection angle angle with respect to Y-axis deflection, the diffusion of oblique both sides, at this moment, be positioned at upper left 3 display units 12 in display unit 11 regions and bottom-right 3 display units 12 and receive diffusion light from display unit 11, its brightness is a little less than display unit 11, constitute the oblique shade of required display image, visually produce stereoeffect, as shown in Figure 4, zone 11 among the figure is the image of required demonstration, visually be rendered as the image of numeral 1,12 in zone is the oblique shade that is produced by after regional 11 the light diffusion.
Fig. 5 is the synoptic diagram of second embodiment of the present invention, with the difference of above-mentioned first embodiment be: be coated with light absorbent layer 18 on the right side of each display unit, its the area of application covers the Zone Full of the right flank of display unit, in this embodiment, the light diffusion of the brightest area 11 of display board central authorities is shown in arrow among the figure, because the coated light absorbent layer 18 in display unit right side, make diffusion light present oblique monolateral ejaculation, therefore, the brightness of the LED unit 15 of display image periphery is very low, almost do not have diffusional effect, can not produce hatching effect, its result makes the image border of generation in sharp contrast; The image of outstanding required demonstration, its visual effect as shown in Figure 6.
Fig. 7 is the synoptic diagram of the 3rd embodiment of the present invention, with the difference of above-mentioned second embodiment be: be coated with reflective material layer 18 on the right side of each display unit, but not light absorbent, the reflection of diffusion light of viewing area 11 that is arranged in display board central authorities is shown in the figure arrow, light reflexes to the lower right corner display unit 14 of viewing area 11, causes slightly hatching effect of the right.The visual effect of present embodiment as shown in Figure 8.
Fig. 9 is the synoptic diagram of the 4th embodiment of the present invention, with the difference of above-mentioned second embodiment be: the light absorbent layer 18 coated on the right side of each display unit covers its regional area, therefore, when light the viewing area 11 that is positioned at display board central authorities, its peripheral display unit 14 still can receive part diffusion light, thereby produces hatching effect.Three on the left side of viewing area 11 and three display units in the right 14 form hatching effect among the figure.The visual effect of present embodiment as shown in figure 10, this visual effect is compared with the visual effect of LED display board of the prior art shown in Figure 2, the black and white gradation that present embodiment presented is more obvious.
