A wired laser display system, comprising: a digital signal processing device receives a request signal sent by a terminal display device, retrieves data from a cable TV network, transmits it to a light splitting / combining device, and simultaneously sends an optical signal to a laser light source device; the laser light source The device generates light source light, and transmits the light source light to the light splitting / combining device respectively through optical fibers; the light splitting / combining device receives the light source light sent by the laser light source device and the signal light of the digital signal processing device, and combines them for transmission , and then split the combined light beam at the front end and transmit it to the end user; the terminal display device is used to send a request / termination signal and receive the signal light and light source light of the light splitting / combining device for imaging display. The large-scale signal transmission of the laser cable TV signal by the present invention has the advantages of small loss, large capacity, strong anti-interference ability, etc.; and provides a laser display system with low price and suitable for use in crowded places.
Description
technical field [0001] The present invention relates to the technical fields of laser display and laser communication, and more specifically, the present invention relates to a laser wired display system. Background technique [0002] Laser light source has obvious advantages in resolution, contrast and color saturation, so laser display, as a new display technology, has more and more applications. First, the laser display has a large color gamut, vivid and rich colors, high color saturation, high resolution, and the color expression is more than twice that of the current traditional TV; second, the laser light source has a long service life and the overall cost of maintenance Low, the laser light source completely breaks the electro-optical conversion mode of the traditional light source, and its lifespan is 10 to 20 times that of the traditional light source; third, high-power lasers are easy to implement, and semiconductor lasers are small in size, light in weight, reliab...
