LASER DISPLAY SYSTEM

Document Type and Number:

WIPO Patent Application WO/2016/011928

Kind Code:

A1

Abstract:

A laser display system. The laser display system comprises a red-light semiconductor laser module (1), a green-light semiconductor laser module (2), a blue-light semiconductor laser module (3), coherence eliminators (7, 8, 9), light valves (12, 13, 14), collimation shaping devices (4, 5, 6), heat dissipation modules (16-1, 16-2, 16-3), a temperature control module (17) and a semiconductor laser control module (18). The red-light semiconductor laser module (1) has an output wavelength range of 635 nm to 670 nm; the green-light semiconductor laser module (2) has an output wavelength range of 515 nm to 530 nm; and the blue-light semiconductor laser module (3) has an output wavelength range of 440 nm to 460 nm. The chroma triangular area can be as large as possible through adjustable wavelengths, and the display colors are richer and brighter. The laser display system has the common advantages of laser display and also has the advantages of electric excitation, high efficiency, long life, all solid states, miniaturization, low cost and adjustable color temperature, so that a larger color range coverage of laser display is realized, and the system can be used to satisfy special demands such as large-screen seamless splicing.
