Low-speckle laser light source and electronic equipment

Abstract

The invention provides a low-speckle laser light source and electronic equipment. Red, green and blue lasers are adopted to bombard a fluorescent module at the same time, by means of the effect that the fluorescent module has high transmissivity on red and green light, narrow-spectrum RGB laser is changed into wide-spectrum laser after passing through the fluorescent module, and the wide-spectrumlaser is output to an imaging light path system at the rear end, so that the color rendering property of the laser can be well maintained, speckles can be reduced, and an excellent picture effect is achieved.

Description

technical field [0001] The invention relates to the field of display technology, more specifically, to a low speckle laser light source and electronic equipment. Background technique [0002] With the continuous development of science and technology, the application of laser light sources in the display field has become more and more extensive. Products that can be seen everywhere such as laser TV, desktop interactive projection, car head-up display, movie theater projection and building beautification have quietly entered the public. line of sight. [0003] Laser light sources have many advantages such as high brightness, small size, long life, energy saving and environmental protection, and can meet most application scenarios. [0004] However, due to the characteristics of narrow spectrum and strong coherence, traditional lasers are prone to interference and produce speckle, which in turn affects the effect of the displayed picture and the imaging quality of the picture....
