Abstract
The utility model provides a DLP (digital light processor) seamless module spliced screen. The DLP seamless module spliced screen comprises a display screen, two or more square frames, back projection boxes and back projection display modules, wherein the square frames, the back projection boxes and the back projection display modules are the same in number; the back projection display modules are arranged in the back projection boxes; the square frames are arranged on the projection surfaces of the back projection boxes; the square frames are connected and spliced into a main screen in a fixed manner; the display screen is connected with the frames of the main screen through flexible assemblies; the back projection display modules are connected with the display screen through a circuit, and communicate with one another in a signal integration manner. The problem that gaps appear when the screen is spliced is solved in a modular manner; meanwhile, the display screen is connected with the square frames through the flexible assemblies, so that the problem that images of a projection screen are locally blurring and distorted caused by the deformation and unevenness of the screen is radically solved.
Description
Technical field
The utility model relates to a kind of display screen technology of rear-projection, particularly the seamless module mosaic screen of a kind of DLP.
Background technology
Along with scientific and technical development, the especially develop rapidly of computer technology and mechanics of communication, large screen display is subject to all the more liking of people.In recent years, in shadow casting technique's development, by image edge-blending technology, image can be shown and to accomplish very greatly, the one-time formed large-scale projection screen of the thing followed seems particularly important.
At present, back projection type projection screen adopts resin plastic glue material mostly, and owing to producing the restriction of line, size can not be done very greatly, and maximum can accomplish 100 o'clock, and the screen of part kind even can only be accomplished 80 o'clock.In order to reach the display effect of giant-screen, a plurality of independent screens need to be spliced.General connecting method need to couple together screen and rear projection box at present, but because screen is plastic cement structure completely, plastic material is subject to the impact of temperature and humidity very large, if plastic cement screen is completely fixed on rear projection box, screen will produce owing to expanding with heat and contract with cold obvious bulging phenomenon.Make like this screen be subject to the acting force of rear projection box, limited the deformation of screen, affected the display effect of image.
Utility model content
For above-mentioned defect and the problem of prior art, the utility model object is to provide the seamless module mosaic screen of a kind of DLP, has solved seam problem between splice type screen and the uneven problem of display screen.
In order to achieve the above object, the utility model is realized by the following technical solutions:
A kind of DLP is seamless module mosaic screen, comprise a display screen, two or more quadras, rear projection box and rear-projection display module, described quadra, the quantity of rear projection box and rear-projection display module is all identical, and rear-projection display module is arranged in rear projection box, quadra is arranged on the projecting plane of rear projection box, between each quadra, by fixed form, connect and be spliced into main screen, the size of described display screen is identical with main screen, and display screen is connected with the framework of main screen by elastomeric element, rear-projection display module is connected with display screen by circuit, and pass through signal integration mode at each rear-projection display module intercommunication.
Further technical scheme, arranges fixture in described main screen, on described display screen, extension spring is set, and described fixture is connected to form elastomeric element in extension spring.
Further technical scheme, is bolted and is spliced into main screen between each quadra.
The utility model adopts modular mode, makes rear projection box, rear-projection display module and quadra form a standard module, and size that can be as required, splices standard module, then display screen is fixed in the module of having spliced.With regard to having avoided display screen to disassemble into each the small screen, need like this problem of splicing.Simultaneously, display screen adopts elastomeric element with being connected on quadra, elastic parts can regulate automatically according to the expansion coefficient of display screen, thereby solved rear projection screen deformation of unevenness that projection screen causes because of environment or climate change, the problem such as come off, fundamentally solved the phenomenon of the smudgy distortion of projection screen image local causing due to hooking injustice.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only an embodiment of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present utility model, omits rear-projection display module in figure.
Fig. 2 is the enlarged drawing of the elastomeric element between display screen and main screen.
Wherein: 1, rear projection box, 2, display screen, 3, quadra, 4, elastomeric element, 5, bolt, 6, fixture, 7, extension spring.
Embodiment
Below in conjunction with accompanying drawing of the present utility model, the technical solution of the utility model is clearly and completely described, obviously, described embodiment is only embodiment of the utility model, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Shown in Fig. 1, a kind of DLP is seamless module mosaic screen, comprise a display screen, six quadras, six rear projection boxes and six rear-projection display modules, rear-projection display module is arranged in rear projection box, rear-projection display module is connected with display screen by circuit, and passes through signal integration mode at each rear-projection display module intercommunication.Each quadra is arranged on the projecting plane of a rear projection box, between each quadra, be bolted into a main screen, the size of display screen is identical with main screen, fixture is set in main screen, extension spring is set on display screen, the elastomeric element that bolt and fixture form, as Fig. 2, display screen is connected with main screen by this elastomeric element.Both the problem that had solved rear projection screen splicing, has solved again the rough phenomenon of display screen.
The above; it is only embodiment of the present utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; can expect easily changing or replacing, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion by the described protection domain with claim.
