Embodiment Construction

[0029] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0030] At present, the relative positional relationship between the laser projection host and the projection screen in the integrated laser projection system needs to strictly follow the positional relationship during the design of the laser projection system, otherwise, it will affect the image quality projected by the laser projection host on the projection screen. display effect.

[0031] Therefore, in the related art, after the integrated laser projection system leaves the factory, the vertical angle of the projection screen in the integrated laser projection system (the angle is the angle between the surface where the projection screen is located and the ground) Angle) cannot be adjusted, resulting in low flexibility of use ...

Abstract

The invention discloses a laser projection system, and belongs to the technical field of projection display. The laser projection system comprises an accommodating shell, a projection optical engine, a projection screen, a supporting seat and a rotating shaft, wherein the accommodating shell can be fixedly connected with the projection screen, and the accommodating shell can also be rotatably connected with the supporting seat through the rotating shaft. When the accommodating shell rotates, the accommodating shell can drive the projection screen to rotate around the axis of the rotating shaft, the included angle between the plane where the projection screen is located and the ground can be adjusted, and the use flexibility of the laser projection system is effectively improved.

Description

technical field [0001] The present application relates to the technical field of projection display, in particular to a laser projection system. Background technique [0002] The laser projection system includes a projection screen and a laser projection host. The laser projection host can project pictures on the projection screen to realize functions such as video playback. [0003] Usually, the projection screen needs to be fixed on the wall. Once the projection screen is fixed and installed, the projection screen is not easy to be moved again. As a result, the current laser projection system can only be used in one position. In order to allow the laser projection system to be used in different locations, the projection screen and the laser projection host can be made into an integrated laser projection system. [0004] However, the relative positional relationship between the laser projection host and the projection screen in the current integrated laser projection syste...
