Abstract
The utility model discloses a display unit which comprises a long and narrow PCB (Printed Circuit Board) and LED illuminants (Light-Emitting Diode), wherein protrusions are arranged on the PCB at fixed intervals, and the LED illuminants are respectively fixed on the protrusions. A control chip used for controlling the LED illuminants is also arranged on the PCB, and electrodes of the LED illuminants are electrically connected with the corresponding output ports of the control chip. Because the LED illuminants are fixed on the protrusions of the PCB, rays emitted by the LED illuminants can not be shielded by the PCB, each LED illuminant can be clearly observed from all the directions, i.e. the contents displayed on a two-dimensional display screen or a three-dimensional display matrix by splicing the display units can be viewed by spectators from all the angles. Moreover, the utility model has simple structure and can finish mounting the display screen or the display matrix by aligning the display units according to a two-dimensional direction or a three-dimensional direction so as to be very convenient.
Description
Technical field
The utility model relates to a kind of display unit, especially a kind of display unit that is used to make up two dimension or three-dimensional display screen or display matrix.
Background technology
Electronic display has obtained general use, is mainly used in uses such as advertisement displaying or information bulletin.This electronic display substantially all is that the two dimension that adopts LED to make shows dot matrix, generally all is merely able to watch in the place ahead of electronic display.Development along with display technique, some novel two-dimensional display or three-dimensional display matrix have appearred, these display device all need to adopt some novel display units to make up, to reach the displaying contents that can both observe display device in all angles or direction.
Summary of the invention
The purpose of this utility model provides a kind of display unit, can clearly observe the display dot of this unit from all directions, and is simple in structure, can build easily as required to form two-dimensional display or 3-D display matrix.
The utility model is to realize above-mentioned purpose like this:
Display unit comprises long narrow shape printed-wiring board (PWB) and LED luminophor, is provided with projection along the position of printed-wiring board (PWB) constant spacing, and described LED luminophor is fixed on the projection; Also be provided with the control chip that is used to control the LED luminophor on printed-wiring board (PWB), the electrode of LED luminophor is electrically connected with the corresponding output port of this control chip.
The beneficial effects of the utility model are: because the LED luminophor is the projection that is fixed on printed-wiring board (PWB), therefore the light that sent of LED luminophor can't be printed wiring board and blocks, can clearly observe each LED luminophor from all directions, that is to say with this unit and build formation two-dimensional display or 3-D display matrix, spectators can watch display screen or the shown content of display matrix from all angles.And simple in structure, only display unit need be arranged the installation that can finish display screen or display matrix according to two dimension or three-dimensional, very convenient.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is a stereographic map of the present utility model;
Fig. 2 is the partial enlarged drawing at A place among Fig. 1;
Fig. 3 is the stereographic map of the another kind of embodiment of the utility model;
Fig. 4 is the stereographic map of the third embodiment of the utility model;
Fig. 5 is the sectional view of hollow plastic pipe.
Embodiment
See figures.1.and.2, display unit comprises long narrow shape printed-wiring board (PWB) 1 and LED luminophor 2, is provided with projection 11 along the position of printed-wiring board (PWB) 1 constant spacing, and described LED luminophor 2 is fixed on the projection 11; Also be provided with the control chip 3 that is used to control LED luminophor 2 on printed-wiring board (PWB) 1, the electrode of LED luminophor 2 is electrically connected with these control chip 3 corresponding output ports.Because LED luminophor 2 is the projections 11 that are fixed on printed-wiring board (PWB) 1, therefore the light that sent of LED luminophor 2 can't be printed wiring board 1 and blocks, can clearly observe each LED luminophor 2 from all directions, that is to say with this unit and build formation two-dimensional display or 3-D display matrix, spectators can watch display screen or the shown content of display matrix from all angles.And simple in structure, only display unit need be arranged the installation that can finish display screen or display matrix according to two dimension or three-dimensional, very convenient.
Because each display unit all needs to communicate with governor circuit, therefore need link to each other with corresponding main control board, for the ease of installing, at least one end of described printed-wiring board (PWB) 1 is provided with the grafting port one, and the grafting port one that passes through between control chip 3 and the main control board carries out data communication.If desired a plurality of display units are coupled together and form the demonstration chain, so just grafting port 12 need be set at the two ends of printed-wiring board (PWB) 1, so that the data transmission between display unit.
Although can both observe each luminous point in all directions, but unavoidably on some direction since on LED structure and printed-wiring board (PWB) and the printed-wiring board (PWB) other elements cause local blocking, make that the brightness and the sharpness of luminous point reduces on these directions.In order to address the above problem, the minimizing control chip 3 that can try one's best, generally speaking a display unit only needs a display chip promptly can control all LED luminophors 2 on this unit.And display unit is need build to form two-dimensional display or 3-D display matrix, for the 3-D display matrix generally also be earlier display unit is arranged that forming arranges behind the two-dimentional display surface again and is formed three-dimensional, therefore can consider the display unit in the same plane is coupled together by corresponding auxiliary printed-wiring board (PWB) earlier, then the control chip in each display unit 3 all is installed in the auxiliary printed-wiring board (PWB) that connects usefulness, also can avoid the problem of control chip 3 shadings, with reference to Fig. 3.
The utility model also provides another structure to improve the problem of shading in addition, have on the position that is provided with LED luminophor 2 diffuse reflector with LED luminophor 2 and near printed-wiring board (PWB) 1 encirclement, the light that the LED luminophor 2 of same position sends forms a luminous point round printed-wiring board (PWB) 1 after the diffuse reflector scattering, so just can avoid causing the unclear problem of local repressentation owing to blocking.
Certain above-mentioned diffuse reflector can adopt multiple material or structure to realize that the simplest method is to use translucent colloid, as glass cement or the like, with colloid LED luminophor 2, printed-wiring board (PWB) 1 is coated to get up to get final product.But the utility model preferred embodiment is, described diffuse reflector is translucent hollow plastic pipe 4, and the printed-wiring board (PWB) 1 of the described LED of being provided with luminophor 2 is set in the plastic tube 4, with reference to Fig. 4 and Fig. 5.Adopt the benefit of hollow plastic pipe 4 to be: can carry out certain protection to the printed-wiring board (PWB) in the pipe 1, LED luminophor 2 and other electronic components etc., as play and prevent extraneous destruction, waterproof insulation or the like effect; Can also improve the rigidity of whole display unit, prevent distortion; Also be convenient to installing and fixing of display unit in addition.
In order further to improve the diffuse effect of hollow plastic pipe 4, the tube wall of described plastic tube 4 is provided with zigzag reflection groove.
