激光显示技术的研究现状及进展

Research Status and Development of Laser Display Technology

摘要: 本文主要介绍了显示技术的发展到国内外激光显示研究现状及进展。自显示技术发展以来，经历了一系列的更新换代，传统显示技术在高清晰视频图像方面已经相当成熟，但是在颜色的高还原问题上却还处于初步研发阶段，没有取得显著进展。随着激光器的出现，显示用光源突破了原有光源的局限性。大色域覆盖率的激光显示的优越性，掀起了显示技术更新换代的热潮。近年激光显示产品，逐渐占据了一定的显示产品的市场份额。促进了显示技术的革命，国内外都加紧制定了激光显示发展战略。用激光取代原有光源的激光显示技术，继黑白、彩色和数字这三种显示技术之后的第四代“继承者”。它具有其独特的优点：色域覆盖的范围更广、使用寿命更长、环保、低功耗。其将给显示行业带来发展机遇，甚至是未来一段时间内主流的显示技术。当激光显示与全息技术结合应用，便会产生一种兼顾两者优势特点的激光全息技术。激光全息的出现，再次促进了显示行业的显著发展。

Abstract: This paper mainly introduces the development of display technology, the research status and progress of laser display at home and abroad. Since the development of display technology, it has experienced a series of updates. The traditional display technology has been quite mature in high-definition video image, but it is still in the initial stage of research and development on the issue of high color restoration, and no significant progress has been made. With the emergence of laser, the light source for display breaks through the limitation of the original light source. The advantages of large color gamut coverage of laser display set off the upsurge of display technology upgrading. In recent years, laser display products gradually occupy a certain market share of display products. It has promoted the revolution of display technology, and the development strategy of laser display has been formulated at home and abroad. Laser display technology, which replaces the original light source with laser, is the fourth generation “successor” of black-and-white, color and digital display technology. It has its unique advantages: wider gamut coverage, longer service life, environmental protection, low power consumption. It will bring development opportunities to the display industry, even the mainstream display technology in the future. When laser display and holographic technology are combined, a laser holographic technology will be produced which takes into account the advantages of both. The appearance of laser holography promotes the development of display industry.
