Embodiment
With reference to Fig. 1, a kind of array of display that is used to make up two dimension or three-dimensional display apparatus, comprise a plurality of wire display units 1, wire display unit 1 is provided with point-like luminophor 2 and is used to control the control circuit 3 of point-like luminophor 2,1 of a plurality of wire display unit are continuous by control signal corresponding line 4, also comprise the supply line that separates with control signal wire 4, supply line is made up of the positive pole and the anode power cord 5,6 of two separation at least, and wire display unit 1 distributes along supply line according to certain interval and fixes and be electrically connected with anodal and anode power cord 5,6.Supply line is separated from control signal wire 4, the power supply of each wire display unit 1 all directly is connected with supply line, supply line can adopt and be used to the copper post of powering merely, power lead and printed-wiring board (PWB) or the like can provide the conducting medium of big electric current, and flowing through all point-like luminophor 2 required electric currents of this unit, 1 need of each wire display unit get final product, this electric current is less relatively, solve the printed-wiring board (PWB) power supply of adopting on the existing display unit like this and caused the limited problem of supply current, so that use this display matrix to make large-scale two dimension or three-dimensional display apparatus, the expansion that display device can be unlimited is unrestricted.
For the ease of building of array of display, the fixing position of wire display unit 1 just, supply line can also be as the support frame of array of display, so that array of display is fixing.As required, display device can have multiple mounting means, and is as horizontal positioned, suspension or the like, also different to the requirement of supply line like this.When horizontal positioned, described positive pole and anode power cord 5,6 are the conducting medium of rigidity, as the conducting metal post etc., form a display plane so that support all wire display units 1.Preferred implementation of the present invention is, with reference to Fig. 2, described positive pole and anode power cord 5,6 are the printed-wiring board (PWB) of long narrow shape, the position that printed-wiring board (PWB) is connected with wire display unit 1 is provided with card 7, fix and be electrically connected by solder joint between wire printed-wiring board (PWB) and the wire display unit 1, this structure can guarantee that the current-carrying part on the whole printed-wiring board (PWB) all is used for the power supply power supply, guarantees to bear bigger electric current and passes through.According to array of display the quantity of wire display unit 1 is set, some card 7 are set on printed-wiring board (PWB) accordingly in advance uniformly, directly wire display unit 1 is snapped in the card 7 during installation, getting final product both are fixing by scolding tin then, very convenient.For hanging the situation of installing, described positive pole and anode power cord 5,6 just can adopt flexible conducting medium, preferred implementation of the present invention is, anodal and anode power cord 5,6 is an enameled wire, to insulate that enamelled coating removes and good just passable in the part that need be connected with 1 welding of wire display unit with wire display unit 1, and enameled wire can prevent to produce between the supply line short circuit, and the reflective of the skin of enameled wire paint is relatively poor simultaneously, can metallic reflective interference display effect.In addition, existing three-dimensional display apparatus generally all can only have the sightingpiston of five directions, because must need a direction as installed surface, be that each display unit all is to be fixedly mounted on the installed surface, but the present invention can address this problem, just can be as sightingpiston in any one direction, because all wire display units 1 all are to fix by supply line, do not need installed surface, therefore use the three-dimensional display apparatus of this array of display manufacturing more excellent viewing angle and effect to be arranged to spectators.
For wire display unit 1, basically all be show state by the point-like luminophor 2 in control circuit 3 this wire of control display units 1, certainly control circuit 3 generally also needs to be controlled by a governor circuit, send control signal by governor circuit by control signal wire 4 and give each wire display unit 1, to plan as a whole the display effect of whole display matrix or even display device.Above-mentioned control circuit 3 can adopt multiple circuit structure to realize, as each wire display unit 1 single-chip microcomputer can be set, single-chip microcomputer is by communication port connection control signal line 4 and other single-chip microcomputers or governor circuit transmission, and single machine output end links to each other with all point-like luminophors 2 of wire display unit 1 then.Preferred implementation of the present invention is, the quantity and the point-like luminophor 2 of the control circuit 3 on the described wire display unit 1 adapt, control circuit 3 generally also is to adopt comparatively simple single-chip microcomputer or miniature special integrated circuit, with low cost and can satisfy the requirement of control, the output port of single-chip microcomputer or control chip links to each other with point-like luminophor 2, connect by serial communication mode between single-chip microcomputer or the control chip, can reduce the wiring on the wire display unit 1 so greatly, width that just can constriction wire display unit 1, can reduce manufacturing cost on the one hand, can reduce the shading of line unit on the other hand, especially for three-dimensional display apparatus, the shading problem can have influence on the display effect of whole device.
With reference to Fig. 4, array of display is according to the certain spacing composition that is arranged in parallel when using as three-dimensional display apparatus with a plurality of array of display, there is the shading problem between the array of display unavoidably,, should dwindles the width of wire wiring board as much as possible therefore in order to reduce shading each other.Described for this reason wire display unit 1 is the printed-wiring board (PWB) of strip, be uniformly distributed with protuberance 11 on the printed-wiring board (PWB), control circuit 3 and point-like luminophor 2 are welded on the protuberance 11, and above-mentioned protuberance 11 area for point-like luminophor 2 is littler, with reference to Fig. 3, can effectively improve the display effect of three-dimensional display apparatus.
