Detailed Description
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
As shown in fig. 1, the display device includes an image source assembly 1 and an optical prism 2. The image source assembly 1 comprises a display area I and a non-display area II, and the optical prism 2 is arranged right above the display area I of the image source assembly. The optical prism is a right-angle triangular prism structure and comprises an image incidence surface 22, an image emergence surface 21 and an image reflection surface 23.
The relative position of the display area I of the image source assembly 1 and the image incidence surface 22 of the optical prism 2 is fixed by disposing a transparent optical adhesive layer therebetween. The source image generated by the image source assembly 1 enters the optical prism 2 through the image entrance surface 22, is projected onto the image reflection surface 23 of the optical prism 2, is reflected on the surface of the image reflection surface 23, and is projected onto the image exit surface 21 to be observed by a user. The position of the imaging plane of the display device 100 is changed by disposing the optical prism 2 on the display area I of the image source assembly 1.
Further, a reflective imaging coating is provided on the surface of the image reflection surface 23 of the optical prism 2 to improve the reflection effect and the imaging quality of the image reflection surface 23. The reflective imaging coating can be made by applying a reflective imaging ink to the surface of the image reflecting surface 23 of the optical prism 2 and curing the reflective imaging ink. Alternatively, a metal with high reflectivity (such as silver) is selected to replace the reflective image forming ink, and a reflective metal layer is disposed on the image reflection surface 23 of the optical prism 2 by electroplating to reflect the image displayed in the display area I of the image source assembly 1.
As shown in fig. 1, the optical prism 2 is a right triangular prism structure, and the cross section thereof is preferably an isosceles right triangle. Since the projected angle is 45 °, the projection ratio is 1: 1. that is, the optical prism 2 projects the image displayed in the display area of the image source assembly 1 onto the image reflection surface 23 of the optical prism 2, and the proportion of the projected image is not changed during the projection process.
The projection ratio can be changed by changing the projection angle of the optical prism 2, for example, the projection angle is 60 °, and the transverse ratio of the projected image is 1: 1, longitudinal ratio of
I.e. the aspect ratio of the source image can be changed by changing the angle of the projection angle.
Referring to fig. 2, in the second embodiment, the cross section of the optical prism 2 is a right-angle trapezoidal quadrangular prism. The volume of the optical prism 2 is reduced while satisfying the projection effect, thereby reducing the overall volume of the display device 200.
In the above embodiment, the edge of the optical prism may be processed to make two adjacent surfaces transition and connect with each other by a slightly curved surface, so as to avoid the edge of the optical prism 2 being too sharp to cause injury to the user.
In other embodiments, the optical prism may have a cavity structure, i.e., the image plane is a telescopic reflective structure, and the exit plane is provided with a telescopic bracket, which is telescopic by the telescopic bracket and the telescopic reflective structure to change the projection angle of the optical prism and change the aspect ratio of the image.
A zoom lens may be disposed between the image source assembly 1 and the optical prism 2 to zoom an image displayed in the display area I of the image source assembly 1, so as to achieve an effect of displaying a large area of image through the small-sized image source assembly 1. Specifically, an image displayed by the small-sized image source assembly 1 is zoomed by the zoom lens, and then is projected to the image reflection surface 23 of the optical prism 2 and then exits toward the image exit surface 21. After the zoom lens selects the magnifying function, the technical effect that the small-sized image source assembly 1 displays a large-area image can be achieved, so as to further reduce the whole area of the display device.
The optical prism 1 is made of a material having heat insulation properties, and plays a role of heat insulation for the image source assembly 2 so as to prevent the image source assembly 1 from being damaged due to overhigh temperature in a high-temperature state. As in summer, the long-time irradiation of sunlight on the image source assembly 1 may cause the local temperature of the surface of the image source assembly 1 to be too high, and the aging of the image source assembly 1 is accelerated. The material with the heat insulation property can be indium tin oxide, composite ceramic nano tungsten oxide or other transparent materials with the heat insulation property.
The invention also provides a display system, which mainly comprises an image source component 1, a prism imaging system 3 and an imaging zooming system 4. The image source assembly 1 is used to generate a source image. The prism imaging system 3 is used for receiving and reflecting the source image generated by the image source assembly 1. The imaging zooming system 4 is arranged between the image source assembly 1 and the prism imaging system 3 and is used for zooming the source image generated by the image source assembly 1.
The prism imaging system 3 is specifically a right-angle triangular prism, and includes an image incident surface 22, an image exit surface 21, and an image reflecting surface 23. The image incident surface 22 and the image exit surface 21 are right-angled surfaces of a right-angled triangular prism, and the image reflecting surface 23 is an inclined surface of a right-angled triangular prism. The aspect ratio of the projected source image can be changed by changing the size of the acute angle of the cross section of the right-angle triangular prism.
The prism imaging system 3 is made of a material with a good heat insulation effect, and plays a heat insulation role on the image source component 1 so as to prevent the image source component 1 from being locally heated and heated up due to the fact that sunlight penetrates directly for a long time, and aging of the image source component 1 is accelerated.
Optical bonding glue with high permeability can be respectively arranged among the image source assembly 1, the prism imaging system 3 and the imaging zooming system 4, so that the relative position is fixed, and meanwhile, the imaging quality of a projected image is prevented from being influenced by adopting other bonding glue.
While the preferred embodiments of the present invention have been described, the present invention is not limited to the above embodiments, and those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and such equivalent modifications or substitutions are intended to be included within the scope of the present invention as defined by the appended claims.
