Abstract

The utility model discloses a space matrix luminescent stereo display device, which comprises a space matrix display, a control circuit and a drive circuit. The space matrix display consists of a plurality of LED dot matrices superimposed up and down. Each LED dot matrix is made by arraying a plurality of LED in matrix and placing the LED on a transparent circuit board. The circuit board and the LED both adopt transparent materials. Positive poles of LED in vertical line are connected in parallel to form a signal input end of the space matrix, negative poles of LED in transverse line are connected in parallel to form a signal output end of the space matrix. The control circuit is connected with the input end and output end of the space matrix via the drive circuit. The device adopts static space matrix to arrange point light sources, displays 360 degrees of the horizontal viewing angle of stereo picture and 270 degrees of vertical viewing angle, acts as active luminescent image type and improves the image quality with regard to brightness, contrast and resolution. The utility model has simple structure and convenient processing technics, and is able to have strong telepresence, reality sense and low manufacturing cost without advanced treatment.

Description

The illuminated 3 d display device of space matrix

Technical field

The utility model relates to the improvement to existing display, discloses the illuminated 3 d display device of a kind of space matrix, belongs to the display instrument technical field.

Background technology

Early stage solid bodies display technique, the main monoblock cube crystal that adopts is as display medium, and the rare earth element of having mixed in crystal is when the relevant infrared laser of two bundles intersects at quartzy certain inner spatial point place, they will excite this point luminous, and this cover system still is in laboratory stage at present.U.S. Enter LightSpace Technologies company has released the DepthCube three-dimensional display in recent years, has represented the higher level of solid bodies display technique.The display medium of DepthCube is laminated by 20 liquid crystal displays, and the resolution of each screen is 1024 * 748, is about 5mm between screen and the screen at interval; Project image onto on a certain liquid crystal display by the DLP technology, and high speed is switched display screen and picture, adopt " three dimensional depth reverse sawtooth " technology to strengthen depth feelings to each screen again, make 1024 * 748 * 20 physical bodies spatial resolution realize 1024 * 748 * 608 display resolution.

But because the restriction of liquid crystal technology itself, the visual angle width of DepthCube display is limited, and higher to the software and hardware technical requirement of supporting, transmitted data amount is big, and cost is higher.

Summary of the invention

The utility model discloses the illuminated 3 d display device of a kind of space matrix, and it is limited to have overcome existing display viewing angles width, and technical conditions require problems such as harshness.

Technical solution of the present utility model is as follows: constitute the illuminated 3 d display device of space matrix by static space matrix, control circuit and driving circuit.

Adopt the mode of the static space matrix pointolite of arranging, space matrix is superposeed up and down by several piece LED dot matrix and constitutes, every LED dot matrix is to be arranged by several LED, be positioned on the transparent circuitry plate and be made, circuit board and LED all adopt the bright material of full impregnated, the visual angle can be expanded to 360 degree as seen;

The positive pole of each perpendicular row LED is connected in parallel and constitutes the signal input part of space matrix, and the negative pole of each horizontally-arranged LED is connected in parallel and constitutes the signal output part of space matrix, and control circuit connects the signal input part and the output terminal of space matrix through overdrive circuit.

In the control circuit, output terminal Q1～Q8 of latch U1～U16 (74LS373) is through the coordinate of a direction of overdrive circuit control 8 * 8 dot matrix.In like manner, Q11～the Q18 of latch is by the input end J1～J8 of driving circuit control LED dot matrix, output terminal-the J1 of Q21～Q28 control LED dot matrix～-J8, just realized a LED dot matrix display image with U1 and U2 by the mode of lining by line scan like this, 16 latchs act on simultaneously and just make eight LED dot matrix all show, form a stereo-picture.

Advantage and progress that the utility model has with respect to prior art: adopt the mode of the static space matrix pointolite of arranging, the stereoscopic images displayed horizontal view angle can reach 360 degree, vertical angle of view 270 degree, simple in structure, processing technology is convenient, need not advanced treating can have strong telepresenc and presence, and production cost is lower.Be active illuminating formula imaging mode, on brightness, contrast and resolution, all improved picture quality.

Embodiment

According to shown in Figure 1, space matrix (1) is made of eight 8 * 8 LED dot matrix (2), the adjacent LED spacing is 7.52mm, every LED dot matrix (2) is that LED is positioned over be made on the transparent circuitry plate (3) (referring to Fig. 2), anodal J1～J8 of perpendicular row LED back from left to right in parallel is the signal input part of space matrix (1) in the LED dot matrix, negative pole-J1 of horizontally-arranged LED～-J8 back in parallel from top to bottom is the signal output part of space matrix (1).

Control circuit as shown in Figure 3, two 3-8 code translator YM1 reorganize into the 4-16 code translator jointly with YM2 (74LS138), four output terminals of the P1.4～P1.7 of single-chip microcomputer (AT89S52) are used for controlling this 4-16 code translator YM1 and YM2, the output signal of code translator is Y1～Y16, connect latch U1～16 by reverser, code translator select Y1 then latch U1 insert the number of P2.0～P2.7, when code translator was not selected Y1, the output of U1 kept original signal constant.When code translator is selected Y2, Y3, Y4.... in like manner.The output terminal Q of latch U1～U16 (74LS373) is through the coordinate of a direction of overdrive circuit control 8 * 8 dot matrix.For example, J1～the J8 of the Q11 of latch～Q18 control LED dot matrix, Q21～Q28 control LED dot matrix-J1～-J8, just realized a LED dot matrix display image with U1 and U2 by the mode of lining by line scan like this, 16 latchs act on simultaneously and just make eight LED dot matrix all show, form a stereo-picture.
