Abstract

A three-dimensional LED display device comprises planar display units and a display control unit for controlling the planar display units. The planar display unit formed by linear display units via wiring comprises a conductor and illuminants, the illuminants are uniformly distributed along the conductor and connected with the conductor. Pluralities of the planar display units are vertically arranged on a two-dimensional plane to form a three-dimensional display matrix. The planar display units are respectively connected with ports corresponding to the display control unit. The display control unit is used for outputting one or a plurality of groups of control signals to lighten corresponding illuminants in the three-dimensional display matrix, thereby enabling the three-dimensional display matrix to display corresponding three-dimensional patterns or cartoons. As extensibility of pixels in a Z-axis direction is capable of reaching 32-128 pixels, pixel pitch can be shortened to 20-30mm, and width of a PCB can be shortened to 2-3mm, thereby the three-dimensional LED display device is capable of displaying clear three-dimensional colorful pictures.

Description

The three-dimensional LED display device

Technical field

The utility model relates to a kind of three-dimensional (X, Y, Z three-dimensional space) LED display.

Background technology

The LED of current two dimension (light emitting diode) display device has obtained general use, and its control technology and manufacturing process are quite ripe, but can only show two dimensional image.Along with the development of display technique, and people have been developed multiple dimension display technologies accordingly to the active demand that 3-D view shows.For example two-dimensional image is fictionalized three-dimensional image by wearing special glasses or display device; Adopt the method for tripleplane, but be not proper 3-D display, and the field of employment is restricted, display area is restricted, can't observe each side of stereo-picture.

In recent years,, attempt to solve the technical matters of 3-D display by LED builds three-dimensional matrice in the space mode, but at present also for failing to solve following key issue.

Problem 1: the picture element expansion difficulty of display screen on Z-direction.Usually the picture element of Z-direction is less than 32 points between 8～24;

Problem 2: the height of display screen on Z-direction has bigger restriction, usually the height of Z-direction is less than 0.5 meter, because the linear structure that is made of PCB (printed circuit board) itself makes the support strength of Z-direction be restricted merely, can't make the Z axle reach higher height, for example above 1.6 meters;

Problem 3: because pixel pitch is bigger, and Z axle picture element is less, and the height of Z axle is lower simultaneously, so the sharpness that shows is very poor, and image fault is (for example when showing the stereotome of the earth, because the picture element of Z axle is few, highly low, will cause the south poles distortion of the earth);

Problem 4: when being fixed on LED on the pcb board, pcb board is in order to hold very many control signals, and the broad that pcb board has to design has so just blocked a lot of picture elements, so display effect is relatively poor.

In sum, the current problem that needs to solve is how to solve the three-dimensional display apparatus problem of display color stereotome clearly.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of three-dimensional LED display device, extendability by picture element on the Z-direction, it can reach 32～128 points, make pixel pitch can be reduced into 20～30mm, the width of PCB can narrow down to 2～3mm, thus three-dimensional colour picture that can clear display.

In order to address the above problem, the utility model provides a kind of three-dimensional LED display device, comprises planar display unit and the indicative control unit that is used to control described planar display unit, wherein,

Described planar display unit is to be made of by line the wire display unit; This planar display unit comprises lead and the luminophor that evenly distributes and be connected with lead along lead; A plurality of planar display unit vertical arrangement constitute the 3-D display matrix in a two dimensional surface; Described planar display unit is connected with the corresponding port of described indicative control unit respectively;

Described indicative control unit is used for exporting one or more groups control signal and lights the corresponding luminophor of described 3-D display matrix, makes the 3-D display matrix display device that corresponding three-D pattern or animation are shown.

Compared with prior art, the utility model adopts novel physical construction and special process structure, has solved the problem that seems contradiction in the current three-dimensional LED display screen technology:

1, the volume of PCB will be tried one's best little (signal wire on the little meaning of the volume PCB is just few, and the intensity of PCB is just little), the last signal wire and the PCB that will hold as much as possible of PCB will have enough intensity;

2, (picture element of Z axle is many more for the height that the height many, the Z axle that the picture element of Z axle will be tried one's best will be tried one's best, the height of Z axle is high more, then just at double increase of the number of signals of being held on the PCB of lowermost end wire display unit, the support strength of Z axle is just more weak), can be by the connection that corresponds to each other of a plurality of wire display units, make the height of Z axle reach or when surpassing 1.6 meters, the picture element of Z axle reaches or surpassing, the last signal wire and the PCB that are multiplied of can holding of PCB can keep enough support strengths at 128;

3, increased PCB when X-axis, Y-axis and Z axle to the blocking of LED luminophor in expansion, but by special process structure, made when some angle is watched three-dimensional screen of the present utility model unaffected;

Use the utility model, (volume of PCB is more little to make the volume of PCB enough little, block surface is just more little, display effect will be good more) situation under, reached the advantage that can not block picture element after enough big, expansions that PCB can also carry out the Z axle of the intensity that but can hold abundant control signal wire, PCB on the PCB and the expansion.
