Description
Technical field
The present invention relates to optical field, particularly relate to a kind of for LED(LightEmittingDiode, light emitting diode) bore hole 3D(Dimensions, dimension) the raster detect method of display screen.
Background technology
Bore hole 3D technology comprises slit grating and column mirror grating technology, and slit grating or column mirror grating by multichannel picture that 2D display screen overlaps separately, send into human eye respectively, thus makes people need not wear any equipment can to form 3D vision.No matter be slit grating or column mirror grating at present, its width is all limited, is difficult to the application requirement meeting large scale LED naked-eye 3D display screen, therefore, just needs the grating raster detect of reduced size being become large format.
Publication number be CN102540305B patent discloses a kind of optical grating counterpoint splicing method, this invention utilizes benchmark interference fringe, adjusts respectively and contraposition all gratings, thus completes the splicing of multiple grating.The shortcoming of the method is that operability is not good, cannot quantize joining quality, thus cause splicing effect not good in a lot of situation.
Summary of the invention
The object of the invention is, a kind of raster detect method is provided, to improve the not good problem of existing raster detect quality.
The invention discloses a kind of raster detect method, for LED naked-eye 3D display screen, said method comprises the following steps:
According to screen size and grating slope, cutting grating, obtains grating to be spliced;
According to the position erection glass substrate of display screen, and light parallax synthesis picture on a display screen;
By grating block-by-block to be spliced splicing on the glass substrate and vernier angle, to ensure all to present same picture in all grating regions of seeing on same position;
Paste fixing for the grating adjusting angle on the glass substrate.
Preferably, above-mentioned grating is column mirror grating or slit grating.
Preferably, the above-mentioned erection of the position according to display screen glass substrate step is specially:
If above-mentioned display screen is vertically placed, then above-mentioned glass substrate is erected at the dead ahead of above-mentioned display screen by bracing frame;
If above-mentioned display screen horizontal positioned, is erected at directly over above-mentioned display screen by bracing frame at above-mentioned glass substrate.
Preferably, above-mentioned grating passes through UV(UltravioletRays, ultraviolet light) the fixing stickup of glue is on the glass substrate.
Preferably, said method is further comprising the steps of:
With UV light irradiation glass substrate, grating is connected with glass substrate.
Preferably, above-mentioned grating is fixing on the glass substrate by super transparent double face glue.
Preferably, said method is further comprising the steps of:
By cold paperhanging machine roll extrusion grating, grating and glass substrate are fitted completely.
The present invention adopts multichannel parallax to synthesize picture and the method for real time calibration location, makes splicing process simplification, process is easily controlled, splicing effect is easier to adjustment, is more suitable for being applied to large format splicing.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide a further understanding of the present invention, forms a part of the present invention, and schematic description and description of the present invention, for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 is the process flow diagram of joining method preferred embodiment of the present invention;
Fig. 2 is two pieces of column mirror grating splicing schematic diagram;
Fig. 3 is the schematic diagram that in Fig. 2, grating 32 shows different pictures before not adjusting angle;
Fig. 4 is the schematic diagram that in Fig. 2, grating 32 shows same picture after adjusting angle.
Embodiment
In order to make technical matters to be solved by this invention, technical scheme and beneficial effect clearly, understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1, be the process flow diagram of joining method preferred embodiment of the present invention, comprise the following steps:
Step S01: according to size and the grating slope of display screen, cutting grating, obtains grating to be spliced;
In the present invention, above-mentioned grating can be column mirror grating also can be slit grating.
Step S02: according to the position erection glass substrate of display screen, and light parallax synthesis picture on a display screen;
If display screen is vertically placed, then glass substrate is erected at the dead ahead of display screen by bracing frame;
If display screen horizontal positioned, is erected at directly over display screen by bracing frame at glass substrate.
Step S03: by grating block-by-block to be spliced splicing on the glass substrate and vernier angle, to ensure all to present same picture in all grating regions of seeing on same position;
Step S04: paste fixing for the grating adjusting angle on the glass substrate.
As shown in Figure 2, be two pieces of column mirror grating splicing schematic diagram, 1 is display screen, and 2 is glass substrate, and 31,32 is grating; The present invention treats jointing grating and carries out block-by-block adjustment angle and fixed position, last global optimization.
As shown in Figure 3, be the schematic diagram that in Fig. 2, grating 32 does not adjust display different pictures before angle, after column mirror grating 31 vernier angle, in position as shown in the figure, the simple eye of people sees that the picture in grating 31 region is A, after adjusting angle, get final product the position of fixed grating 31; The angle of column mirror grating 32 is not adjusted, in position as shown in the figure, the simple eye of old friend sees that the picture in grating 32 region is B;
As shown in Figure 4, in Fig. 2, grating 32 shows the schematic diagram of same picture after adjusting angle, in figure, grating 31,32 angle mixes up all, and now, in position as shown in the figure, the simple eye of people sees that the picture in grating 31,32 region is A, now, grating 31,32 position all can be fixed, and splicing completes.
In the present invention, can being pasted fixing for grating on the glass substrate by UV glue, now, in order to make grating be connected with glass substrate, UV light irradiation glass substrate can be used further, with UV curing glue; Also paste fixing for grating on the glass substrate by super transparent double face glue, now, in order to make grating and glass substrate fit completely, can further by cold paperhanging machine roll extrusion grating, to eliminate the bubble between double faced adhesive tape and glass substrate and Grating Film.
Above-mentioned explanation illustrate and describes the preferred embodiments of the present invention, but as previously mentioned, be to be understood that the present invention is not limited to the form disclosed by this paper, should not regard the eliminating to other embodiments as, and can be used for other combinations various, amendment and environment, and can in invention contemplated scope described herein, changed by the technology of above-mentioned instruction or association area or knowledge.And the change that those skilled in the art carry out and change do not depart from the spirit and scope of the present invention, then all should in the protection domain of claims of the present invention.
