Problems solved by technology

[0006] However, since lasers lose a lot of energy during imaging, the greater the number of lasers, the more energy will be lost. Relying on simply increasing the number of lasers cannot achieve the ideal brightness and clarity, but instead makes the heat concentration of the laser projection device Larger, causing serious heat dissipation problems and increasing the risk factor

Embodiment Construction

[0024] In order to make the content of the present invention clearer and easier to understand, the content of the present invention will be further described below in conjunction with the accompanying drawings. Of course, the present invention is not limited to this specific embodiment, and general replacements known to those skilled in the art are also covered within the protection scope of the present invention.

[0025] The projection system in the present invention includes: a micro-projection module and a projection adapter part. The micro-projection beam is emitted by the micro-projection module. The micro-projection light beam emitted by the micro-projection module is received by the projection adapter part, and the phase difference pre-correction is performed on the micro-projection light beam, so as to obtain the target projection image. In addition, in order to obtain large-format projection images and further correct the phase difference of the micro-projection lig...

Abstract

The invention provides a projection system. The projection system comprises micro-projection modules and projection switch-over components, wherein the micro-projection modules are used for emitting micro-projection beams; the projection switch-over components are opposite to the micro-projection modules and are used for receiving the micro-projection beams emitted by the micro-projection modulesand pre-correcting phase differences of the micro-projection beams so as to obtain a target projection image. According to the projection system, by carrying out phase difference pre-correction through projection switch-over lens, the finally formed micro-projection beams are spliced into a complete target projection image, the target projection image does not have splicing seams and observable image quality defect and has a regular shape, and meanwhile, the resolution ratio is increased; and furthermore, by reflecting through reflection components, the micro-projection beams are further amplified, so that the super-large-sized projection image can be obtained.

Description

technical field [0001] The invention relates to the field of projection technology, in particular to a projection system. Background technique [0002] With the development of science and technology, projection devices are becoming more and more miniaturized and portable. Therefore, laser projection devices have emerged as the times require. Due to their small size and high brightness, laser projection devices have attracted widespread attention and have been put into commercial production. However, even if the laser brightness of the laser projection device is high, under white light or in areas with strong light, the picture projected by the laser projection device is relatively unclear, which also affects the light intensity and clarity of the projection device. Come to great challenge. [0003] How to improve the brightness and definition of the laser projection device without increasing or reducing the volume of the semiconductor laser used in the existing laser light ...
