The method enables the splicing process to be simplified and the process to be easy to grasp.
Description
Technical field
The present invention relates to optical field, relate in particular to a kind of for LED(Light Emitting Diode, light emitting diode) bore hole 3D(Dimensions, dimension) the grating joining 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 the multichannel picture overlapping on 2D display screen separately, are sent into respectively human eye, can form 3D vision thereby make people need not wear any equipment.No matter be slit grating or column mirror grating at present, its width is all limited, is difficult to meet the application requirements of large scale LED bore hole 3D display screen, therefore, just the grating of reduced size need to be spliced into the grating of large format.
Publication number is that the patent of CN102540305B discloses a kind of optical grating counterpoint splicing method, and this invention utilizes benchmark interference fringe, all gratings is adjusted respectively and contraposition, thereby completed the splicing of multiple gratings.The shortcoming of the method is that operability is not good, cannot quantize joining quality, thereby caused splicing effect not good in a lot of situations.
Summary of the invention
The object of the invention is, a kind of grating joining method is provided, to improve the not good problem of existing grating joining quality.
The invention discloses a kind of grating joining method, for LED bore hole 3D display screen, said method comprises the following steps:
According to screen size and grating slope, cutting grating, obtains grating to be spliced;
Set up glass substrate according to the position of display screen, and on display screen, light the synthetic picture of parallax;
Grating block-by-block to be spliced is spliced on glass substrate and vernier angle, all to present same picture in all grating regions that guarantee to see on same position;
The grating of adjusting angle is fixedly sticked on glass substrate.
Preferably, above-mentioned grating is column mirror grating or slit grating.
Preferably, the above-mentioned position according to display screen is set up glass substrate step and is specially:
If above-mentioned display screen is vertically placed, 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, be erected at by bracing frame at above-mentioned glass substrate above-mentioned display screen directly over.
Preferably, above-mentioned grating is by UV(Ultraviolet Rays, ultraviolet light) glue fixedly sticks on 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 fixed on 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 the method for the synthetic picture of multichannel parallax and real time calibration location, makes to splice that process simplification, process are easily controlled, splicing effect is easier to regulate, be 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 is used 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 column mirror grating splicing schematic diagram;
Fig. 3 is that in Fig. 2, grating 32 is not adjusted the front schematic diagram that shows different pictures of angle;
Fig. 4 is that in Fig. 2, grating 32 is adjusted the schematic diagram that shows same picture after angle.
Embodiment
In order to make technical matters to be solved by this invention, technical scheme and beneficial effect clearer, clear, 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, is 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 the size of display screen and grating slope, cutting grating, obtains grating to be spliced;
In the present invention, above-mentioned grating can be that column mirror grating can be also slit grating.
Step S02: set up glass substrate according to the position of display screen, and light the synthetic picture of parallax on display screen;
If display screen is vertically placed, glass substrate is erected at the dead ahead of display screen by bracing frame;
If display screen horizontal positioned, be erected at by bracing frame at glass substrate display screen directly over.
Step S03: grating block-by-block to be spliced is spliced on glass substrate and vernier angle, all to present same picture in all grating regions that guarantee to see on same position;
Step S04: the grating of adjusting angle is fixedly sticked on glass substrate.
As shown in Figure 2, be two 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 fixed position, last global optimization.
As shown in Figure 3, be that in Fig. 2, grating 32 is not adjusted the schematic diagram that shows different pictures before angle, after column mirror grating 31 vernier angles, the simple eye of people sees that in position as shown in the figure the picture in grating 31 regions is A, adjust after angle, get final product the position of fixed grating 31; The angle of column mirror grating 32 is not adjusted, and the simple eye of old friend sees that in position as shown in the figure the picture in grating 32 regions is B;
As shown in Figure 4, in Fig. 2, grating 32 is adjusted the schematic diagram that shows same picture after angle, in figure, grating 31,32 angles all mix up, and now, the simple eye of people sees that in position as shown in the figure the picture in grating 31,32 regions is A, now, grating 31,32 positions all can be fixed, and splicing completes.
