Embodiment Construction
[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.
[0022] see figure 1 As shown, the present invention provides a red light semiconductor area array light source device for laser display, which includes:
[0023] A VCSEL array 101, which is used to output circular laser beams, and the spatial coherence of the beams output by multiple VCSELs is weakened, thereby weakening the influence of laser speckle on the laser projection display system, thereby playing a role of decoherence ;The array packaging method refers to figure 2 As shown, it is an N×M surface array composed of a plurality of VCSEL chip units 102, and the number of chips in the length and width directions is determined to be 16:9; The optical path is simplified, and the utilization rate of light energy is im...
