| 摘要 | 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), a decoherence device (7, 8, 9), light valves (12, 13, 14), collimating and shaping devices (4, 5, 6), a heat dissipating modules (16-1, 16-2, 16-3), a temperature control module (17) and a semiconductor laser control module (18). The wavelength range output by the red light semiconductor laser module (1) is from 635 nm to 670 nm; the wavelength range output by the green light semiconductor laser module (2) is from 515 nm to 530 nm; the wavelength range output by the blue light semiconductor laser module (3) is from 440 nm to 460 nm. The present invention achieves a chromatic triangle area as large as possible through tunable wavelengths, provides more abundant and bright display color, and has not only common advantages of laser display but also advantages such as electrical excitation, high efficiency, long service life, all-solid state, miniaturization, low cost, and tunable color temperature, thereby achieving a larger color gamut coverage of the laser display and being applied to particular requirements such as large screen display seamless splice. |
