Description
Technical field
The invention belongs to three-dimensional LED technical field of flat panel display, relate to the method for making of a kind of three-dimensional LED display module.
Background technology
The commercial stereo display mode of current relative maturity adopts electronic shutter formula and polarization projection two kinds of forms usually.Electronic shutter formula 3D display need observer's carrying electronic shutter stereo spectacles, the program not only when attendance is more watch cost higher, and due to image left and right two be sharp-eyed speed switch, visual fatigue and spinning sensation can be caused.Polarization projection 3D installs left and right rounding polaroid respectively additional before being presented at Liang Tai projector, image, through merging modulation, can set up into polarization 3D display system.Spectators are by wearing polaroid glasses, the images of left and right eyes position of glasses is equipped with the left and right rounding polaroid corresponding with the left and right rounding polaroid installed additional before two projector respectively, make left and right two of beholder can only see the image that a projector is launched respectively, generation parallax effect like this, produces 3D stereo display effect.
Above-mentioned polarization-type three-dimensional displaying principle equally also can be applicable in LED stereo display, left and right rounding polaroid is installed additional respectively before the odd, even row (column) of LED display pixel, spectators are equipped with the polaroid glasses of left and right rounding polaroid respectively by wearing images of left and right eyes position, viewing 3D display.But before simply left and right rounding polaroid directly being clamped LED display, need higher mechanical registeration and keep precision, significantly increasing cost.
Applicant have submitted " method for making of a kind of integrated LED 3-D display module and display screen " on April 16th, 2014, and (application number: 201410153359.2), this three-dimensional LED display module adopts two kinds of method for makings.The first first on display module, is coated with one deck casting glue, then left and right rounding polarisation bar is alternately pasted onto odd, even row casting glue showing module or the corresponding position of odd, even row; Then smooth glass plate by its compacting, then put into vacuum tank and vacuumize, finally take out solidification in the display module upper cover pasting polarisation bar, makes three-dimensional LED display module.The second is first pasted onto by adhesive tape on display module; Then on left-handed polarization bar, enclose layer protecting film, the left-handed polarization bar with diaphragm is pasted onto in the first row or first row LED pixel along its length gradually, glues polarisation bar scraper plate and the bubble between polarisation bar and adhesive tape is driven out of; Then on dextrorotation polarisation bar, enclose layer protecting film, then the dextrorotation polarisation bar with diaphragm is pasted onto in the second row or secondary series LED pixel along its length gradually, glue polarisation bar scraper plate and the bubble between polarisation bar and adhesive tape is driven out of; Repeat said process, the left and right polarisation bar that revolves alternately is pasted onto the display odd, even row of module or the corresponding position of odd, even row.First method is when casting glue, and the casting glue of edge easily trickles downwards, affects the splicing between module and module, and complex process, set time is long, is not easy to realize; Polarisation bar is not easily pasted smooth.Second method is when environment temperature is higher, and edge easily tilted because 3M transparent double face glue lost efficacy.
Summary of the invention
The technical problem to be solved in the present invention is to provide the method for making of a kind of integrated form three-dimensional LED display module, and the method technique is simple, and surfacing, will cause edge to tilt due to the change of environmental factor.
In order to solve the problems of the technologies described above, integrated form three-dimensional LED display module method for making of the present invention comprises the steps:
Step one: left-handed, dextrorotation polarisation bar are alternately adhesively fixed on glued membrane, and the position of left-handed, dextrorotation polarisation bar corresponds in the odd, even row LED pixel or odd, even row LED pixel that LED shows module, obtains 3D glued membrane;
Step 2: show on module at LED and be coated with one deck printing opacity glue;
Step 3: left-handed for 3D glued membrane, dextrorotation polarisation bar are pasted onto LED down and show on module; After printing opacity adhesive curing, take glued membrane off obtain integrated form three-dimensional LED display module.
Glued membrane used in described step one shows module odd, even row LED pixel column spacing or mark line corresponding to odd, even row LED pixel column spacing with LED.When pasting left-handed, dextrorotation polarisation bar, left-handed, dextrorotation polarisation bar can be alignd with mark line and paste, ensure to paste LED and show left-handed after on module, dextrorotation polarisation bar and aim at odd, even row LED pixel or odd, even row LED pixel.
In described step one, mechanical arm also can be adopted to pick up left-handed, dextrorotation polarisation bar, be ensured in the odd, even row LED pixel that position alignment that is left-handed, dextrorotation polarisation bar shows module or odd, even row LED pixel by the mode of adjustment mechanical arm displacement.
The glue of printing opacity described in step 2 is UV glue; 3D glue-film stickup is shown after on module to LED, with Ultraviolet radiation 30 ~ 100s, obtains integrated form three-dimensional LED display module.
Advantage of the present invention:
1, first left-handed, dextrorotation polarisation bar are alternately adhesively fixed on glued membrane, then left-handed, dextrorotation polarisation bar being passed down through printing opacity glue shows on module at LED, and in the odd, even row LED pixel that the position of left-handed, dextrorotation polarisation bar corresponds to display module or odd, even row LED pixel, technique is simple, easy realization, and surfacing, will cause edge to tilt due to the change of environmental factor.
2, adopt UV glue left-handed, dextrorotation polarisation bar to be pasted onto LED to show on module, UV glue can not trickle downwards, and set time is short, substantially reduces Production Time, improves production efficiency.
