Embodiment Construction

[0031] The present invention provides a screen speckle removal system and a speckle removal method thereof. In order to make the purpose, technical solution and advantages of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] The screen speckle removal system and speckle removal method provided by the present invention are aimed at the phenomenon of diffraction and diffuse reflection when the image is projected onto the screen by laser, and some light will be reflected to the eyes of the audience. The laser itself has strong energy, and the reflected light enters the human eye. When the reflected light stays on the retina for more than 0.02 seconds, due to the visual delay of the human eye, speckle problems...

Abstract

The invention discloses a screen speckle removing system and a speckle removing method thereof. The screen speckle removing system comprise multiple transducers used for vibrating a screen, an intelligent controller used for calculating vibrating data corresponding to the transducers according to screen parameters and multiple vibrating source scanners used for analyzing the vibrating data and correspondingly controlling the transducers; the intelligent controller is connected with the vibrating source scanners separately; the vibrating source scanners are connected with the transducers in a one-to-one corresponding mode; by enabling the screen to vibrate, reflection rays can be randomly reflected to the other directions in a diffusing mode, the reflection rays dynamically change, that is to say, the requirement can be met by achieving dynamic diffuse reflection of the light rays when certain frequency of screen vibrating is achieved, generation of screen speckles is greatly reduced, the speckles can be even completely removed, the effect is good, the cost is low, the user experience is improved, and great convenience is brought.

Description

technical field [0001] The invention relates to the technical field of laser projection systems, in particular to a screen speckle removal system and a speckle removal method thereof. Background technique [0002] Laser projection is known to have advantages such as longevity (to be added). However, when the image is projected onto the screen through the laser, diffraction will occur, and some light will be reflected to the eyes of the audience. In addition, the laser itself has strong energy, and the reflected light enters the human eye. When the reflected light hits the retina When the dwell time exceeds 0.02 seconds, due to the visual delay of the human eye, speckles will appear visually, which brings great inconvenience to users. The phenomenon of scattered screens seriously affects the quality of projection images, especially the problem of screen speckle in laser projection systems, which must be solved in the industry. Existing solutions, such as adjusting the laser...
