本发明属于LED电子产品应用领域，具体涉及一种可升降LED显示屏。The invention belongs to the application field of LED electronic products, and in particular relates to a liftable LED display screen.
背景技术Background technique
LED技术是21世纪发展最快的一项高科技技术，随着与传统产业的结合，LED技术展现出巨大的市场应用潜力，高端LED产品也越来越具市场竞争力。随着各国城市广告行业的发展，LED显示屏的应用越来越普及，特别是高清超大的LED显示屏，在各种大型组织或活动中更是体现出强大的需求力。但是，在LED显示屏的清晰度、面积大小及运动范围上，更多的只是局限在固有位置较小面积内，这无疑限制了LED产品的应用范围，也阻碍了LED市场的进一步发展。所以，LED行业对一种高清、超大、自动化的可伸缩LED显示屏的需求就显得日益急迫。LED technology is the fastest-growing high-tech technology in the 21st century. With the combination with traditional industries, LED technology has shown huge market application potential, and high-end LED products are becoming more and more competitive in the market. With the development of the advertising industry in cities in various countries, the application of LED displays is becoming more and more popular, especially the high-definition and super-large LED displays, which have shown strong demand in various large-scale organizations or activities. However, in terms of the clarity, area size and range of motion of LED displays, they are more limited to the smaller area of the inherent position, which undoubtedly limits the application range of LED products and hinders the further development of the LED market. Therefore, the LED industry's demand for a high-definition, super-large, and automated scalable LED display is becoming increasingly urgent.
对我国led显示屏产业在规模发展的同时，产品技术推陈出新，一直保持比较先进的水平。90年代初即具备了成熟的16级灰度256色视频控制技术及无线遥控等国先进水平技术，近年在全彩色led显示屏、256级灰度视频控制技术、集群无经线控制、多级群控技术等方面均有国内先进、达到国际水平的技术和产品出现；led显示屏控制专用大规模集成电路也已由国内企业开发生产并得到应用。但是与国外先进技术相比，依然有部分关键技术有待提高：While my country's LED display industry is developing on a large scale, product technologies are constantly being introduced and kept at a relatively advanced level. In the early 1990s, it possessed mature 16-level grayscale 256-color video control technology and wireless remote control and other national advanced level technologies. In terms of control technology and other aspects, there are domestic advanced technologies and products that have reached the international level; LED display control dedicated large-scale integrated circuits have also been developed, produced and applied by domestic enterprises. However, compared with foreign advanced technologies, there are still some key technologies that need to be improved:
一是亮度不足问题。LED显示屏的主要优势是对多变复杂的户外环境的超强适应力，户外环境的特点要求LED显示屏要在晴天、阴天、雨雪天气、远距离、多视角上都能保证足够的亮度来传递信息，因此亮度尤为重要，而由于LED亮度不足，使得目前LED在照明行业中只能充当配角，主要用于装饰，这对于上万颗LED的综合运用更是一项巨大的挑战。One is the problem of insufficient brightness. The main advantage of the LED display is its super adaptability to the changing and complex outdoor environment. The characteristics of the outdoor environment require that the LED display can ensure sufficient viewing in sunny days, cloudy days, rainy and snowy weather, long-distance, and multiple viewing angles. Brightness is used to convey information, so brightness is particularly important. However, due to the insufficient brightness of LEDs, LEDs can only play a supporting role in the lighting industry and are mainly used for decoration. This is a huge challenge for the comprehensive use of tens of thousands of LEDs.
二是LED色差问题。单个LED的应用，基本上不存在色差问题，但将众多LED进行综合运用的话，色差问题就会凸现出来。虽然已有技术来改善此问题，但由于国内技术和生产水平所限，同一色区同一批次LED中仍然存在差异，而且这种差异很难逃脱肉眼的挑剔，从而难以保证LED显示屏的色彩还原性和逼真性。The second is the problem of LED color difference. The application of a single LED basically does not have the problem of chromatic aberration, but if many LEDs are used comprehensively, the problem of chromatic aberration will become prominent. Although there are existing technologies to improve this problem, due to the limitation of domestic technology and production level, there are still differences in the same batch of LEDs in the same color area, and this difference can hardly escape the pickiness of the naked eye, so it is difficult to guarantee the color of the LED display. Restoration and realism.
三是LED显示控制芯片。超大真彩高分辨率LED电子显示屏作为一种新的显示媒体，以其清晰的图像和高性能的播放能力，愈来愈受到人们的重视。而对于LED显示单元来讲，三基色LED管芯是其核心器件，因此应使用波长相差小和发光强度一致性好的高质量管芯，而此种技术主要掌握在世界知名大公司手中，如日本的日亚公司等。四是散热性。由于户外环境温度变化极大，再加之显示屏工作时本身要产生一定的热量，如果环境温度过高又加之散热不良，将很可能导致集成电路工作不正常，甚至被烧毁，从而使显示系统无法正常工作。The third is the LED display control chip. As a new display medium, ultra-large true-color and high-resolution LED electronic display has attracted more and more attention for its clear images and high-performance playback capabilities. As for the LED display unit, the three-color LED core is its core device, so high-quality tube cores with small wavelength difference and good luminous intensity consistency should be used, and this technology is mainly in the hands of world-renowned large companies, such as Japan's Nichia Corporation and so on. The fourth is heat dissipation. Because the temperature of the outdoor environment changes greatly, and the display itself generates a certain amount of heat when it is working, if the ambient temperature is too high and the heat dissipation is not good, it is likely to cause the integrated circuit to work abnormally or even be burned, so that the display system cannot be used. normal work.
随着经济全球化的发展，知识产权日益成为国际竞争的焦点，知识产权通常包括专利、商标和版权，具有地域性，例如美国的专利权只能在美国拥有权利。同时，知识产权也是国家与企业重要的战略资源。2008年6月5日，中国《国家知识产权战略纲要》正式颁布实施，提出必须把知识产权战略作为国家重要战略，切实加强知识产权工作。在LED领域，专利诉讼此起彼伏，一波未平一波又起；而LED产业中上游的专利技术，主要集中在外国企业手里，也就是说，外国企业把握了专利战略主动权。LED产业市场广泛，前景光明；而我国LED行业起步相对较晚，但发展速度迅猛，知识产权问题逐渐成为行业进行快速赶超的瓶颈，如何尽快适应国际游戏规则、切实加强知识产权工作、实现专利突围，是我国LED行业必须解决的问题。With the development of economic globalization, intellectual property rights have increasingly become the focus of international competition. Intellectual property rights usually include patents, trademarks and copyrights, which are regional. For example, patent rights in the United States can only be owned in the United States. At the same time, intellectual property is also an important strategic resource for the country and enterprises. On June 5, 2008, China's "National Intellectual Property Strategy Outline" was officially promulgated and implemented, and it was proposed that the intellectual property strategy must be regarded as an important national strategy to effectively strengthen intellectual property work. In the field of LED, patent lawsuits come one after another, and the patented technology in the upper and middle reaches of the LED industry is mainly concentrated in the hands of foreign companies, that is to say, foreign companies have grasped the initiative of the patent strategy. The LED industry has a broad market and a bright future; while my country's LED industry started relatively late, but it is developing rapidly. Intellectual property issues have gradually become the bottleneck for the industry to quickly catch up. How to adapt to international game rules as soon as possible, effectively strengthen intellectual property work, and realize patents Breaking through is a problem that my country's LED industry must solve.

However, the LED display screens installed on some large buildings or buildings have to consider many factors such as windproof, light transmission, and aesthetics. However, there are also certain limitations.
