Description
Technical Field
The utility model belongs to the technical field of the projector, concretely relates to projection system of screen self-luminous.
Background
As society develops, various display applications emerge in endless ways, where the projection occupies a significant portion of it. The projection system displays the image projected by the projector by using the principle that the target screen scatters the image into human eyes, and the defect of the scheme is that the ambient light resistance is weaker. If the ambient light ratio is stronger, the display effect of the projection is affected, and if a better effect is desired, the output brightness of the projection itself is increased, which brings about a great cost increase.
Therefore, it is necessary to design a projection system with self-luminous screen to solve the above technical problems.
Disclosure of Invention
In order to overcome the defects in the prior art, the present invention provides a projection system with self-luminous screen.
In order to achieve the above objects and other related objects, the present invention provides a technical solution: a projection system with self-luminous screen comprises a projection system, wherein the projection system comprises a projector, a self-luminous projection screen and a reflecting plane, the self-luminous projection screen is a projection screen which is excited by projection light of the projector to emit light, the projector is arranged on one side of the self-luminous projection screen, and an emission source of the projector is aligned with the front surface of the self-luminous projection screen; the reflecting plane is attached to the back of the self-luminous screen.
Preferably, the self-luminous projection screen contains photoluminescent nano-materials.
Preferably, the reflection plane is a white material with high reflectivity attached to the back of the self-luminous projection screen.
Preferably, the reflecting plane is a reflecting film plated on the back of the self-luminous projection screen.
Because of the application of the technical scheme, compared with the prior art, the utility model the advantage that has as follows:
according to the projection system with the self-luminous screen, the screen can be excited by projection light of the projector to have the self-luminous function, meanwhile, the reflection plane can reflect the light projected by the projector to penetrate through the screen, the ambient light resistance of the projection system is greatly improved, the display brightness is effectively improved, and the system cost is reduced.

Detailed Description
The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.
Please refer to fig. 1. It should be understood that the structure, ratio, size and the like shown in the drawings attached to the present specification are only used for matching with the content disclosed in the specification, so as to be known and read by those skilled in the art, and are not used for limiting the limit conditions that the present invention can be implemented, so that the present invention has no technical essential meaning, and any structure modification, ratio relationship change or size adjustment should still fall within the scope that the technical content disclosed in the present invention can cover without affecting the function that the present invention can produce and the purpose that the present invention can achieve. Meanwhile, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for convenience of description, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof may be made without substantial technical changes, and the present invention is also regarded as the scope of the present invention.
Example (b): as shown in fig. 1, a projection system with self-luminous screen includes a projection system, the projection system includes a projector, a self-luminous projection screen, and a reflection plane, the self-luminous projection screen is a projection screen excited by projection light of the projector to emit light, and the self-luminous projection screen contains nano-material with photoluminescence; the projector is positioned on one side of the self-luminous projection screen, and an emission source of the projector is aligned to the front side of the self-luminous projection screen; the reflecting plane is attached to the back of the self-luminous screen; the reflecting plane can be a high-reflectivity white material attached to the back of the self-luminous projection screen, and can also be a reflecting film plated on the back of the self-luminous projection screen.
The self-luminous projection system of the screen designed by the scheme has the self-luminous function by the projection light excitation of the projector, the self-luminous projection screen contains the photoluminescent nano material, and the nano material is matched with other materials and can be made into films, projection screens, glass, hard projection screens and the like. When light with a specific wavelength projected by the projector irradiates on the nanometer material, the nanometer material is excited by excitation light, and the color of the excitation light depends on the combination of the wavelength of the projection light of the projector and different nanometer materials; meanwhile, a high-reflectivity white material (such as an electronic whiteboard) is attached to the back surface of the self-luminous projection screen or a reflecting film is plated on the back surface of the self-luminous projection screen, so that a reflecting plane is formed, and the reflectivity of the reflecting plane is at least over 80%; the benefits of this are: when light projected by the projector passes through the projection screen, a part of the light can excite the nanometer material to emit light, and a part of the light penetrates through the projection screen and is wasted; the reflecting plane can reflect the part of light to the projection screen by the high-reflectivity material on the plane, and excite the nanometer material to emit light again, so that the total excitation efficiency of the system is increased; the excitation light of the nano-material is 360 degrees luminous, so that the excitation light towards the back of the projection screen is wasted. By using a reflective plane, this portion of light will be reflected by the highly reflective material on the back of the screen towards the viewer, increasing the efficiency of the system's excitation light.
The above embodiments are merely illustrative of the principles and effects of the present invention, and are not to be construed as limiting the invention. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which may be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
