Description
Technical field
The invention belongs to the sub-product applications of LED electrical, be specifically related to a kind of liftable LED display.
Background technology
LED technology is a 21 century high-tech technology with fastest developing speed, and along with the combination with conventional industries, LED technology shows huge market application potential, and high-end LED product also more and more has a market competitiveness.Along with the development of various countries' city advertisement industry, the application of LED display is more and more universal, particularly the LED display of high definition super large, in various large organization or activity, embody powerful demand force especially.But on the sharpness of LED display, size and range of movement, be more just confined to fixed position comparatively in small size, this limits the range of application of LED product undoubtedly, also counteracts that further developing of LED market.So the demand of LED industry to the Telescopic LED display screen of a kind of high definition, super large, robotization just seems day by day urgent.
To China led display screen industry while scale development, product technology is weeded out the old and bring forth the new, and keeps more advanced level always.Namely having possessed state's advanced level technology such as 16 grades of ripe gray scale 256 look video control technologys and wireless remote control the beginning of the nineties, in recent years having occurred without all having domestic advanced person, the technology reached international standards and product in line traffic control, multistage group control technology etc. at full color led display screen, 256 grades of greyscale video control technologys, clusters; Led display screen controls specialized large scale integrated circuit and is also applied by domestic enterprise's Development and Production.But compared with advanced foreign technology, still have Some Key Technologies to have much room for improvement:
One is luminance shortage problem.The main advantage of LED display is the superpower adaptive faculty of the outdoor environment to changeable complexity, the feature of outdoor environment requires that LED display will can ensure that enough brightness carrys out transmission of information in fine day, cloudy day, sleety weather, remote, various visual angles, therefore brightness is particularly important, and due to LED luminance deficiency, make current LED can only stooge in illuminating industry, be mainly used in decoration, this integrated use for LEDs up to ten thousand is a huge challenge especially.
Two is LED aberration problems., there is not aberration problem in single led application, but numerous LED is carried out integrated use substantially, and aberration problem will show especially out.Although prior art improves this problem, but because domestic technique and production level limit, still there are differences with in same batch of district of the same colour LED, and this species diversity is difficult to escape the fastidious of naked eyes, thus is difficult to the color reducibility and the verisimilitude that ensure LED display.
Three is LED display control chips.The very color high-resolution LED electronic display of super large, as a kind of new display media, with its image and high performance ability to play clearly, is more and more subject to people's attention.And for LED display unit, three-primary color LED tube core is its core devices, wavelength therefore should be used to differ little and that luminous intensity consistance is good high quality die, and this kind of technology mainly rest in world-famous major company hand, as the Ya company etc. of Japan.Four is thermal diffusivities.Because outdoor environment temperature variation is very big, itself to produce certain heat during display screen work in addition, dispel the heat again bad if environment temperature is too high in addition, will probably cause integrated circuit operation abnormal, even burnt, thus display system cannot normally be worked.
Along with the development of economic globalization, intellecture property becomes the focus of international competition day by day, and intellecture property generally includes patent, trade mark and copyright, has region, and the patent right of the such as U.S. can only have right in the U.S..Meanwhile, intellecture property is also the strategic resource of country and enterprise-essential.On June 5th, 2008, China's " state intellectual property right strategy outline " formally issues and implements, and proposition using intellectual property strategy as national grand strategy, must strengthen Intellectual Property conscientiously.In LED field, patent action rises one after another, and one trouble comes after another; And the patented technology of LED industry middle and upper reaches, mainly concentrate in foreign enterprise hand, that is, foreign enterprise has held patent strategy initiative.LED industry market is extensive, has a bright future; And the starting of China LED industry is relatively late, but speed of development is swift and violent, Intellectual Property Rights Issues becomes the bottleneck that industry is caught up with and surpassed fast gradually, and how adapting to international game rule as early as possible, conscientiously strengthen Intellectual Property, realize patent breakthrough, is the problem that China's LED industry must solve.
The diversified development of outdoor display screen, make increasing occasion that large LED display screen has all been installed, but, in the LED display of some large buildings or architectural setting, when considering windproof, printing opacity, the many factors such as attractive in appearance, also there is certain limitation.
Summary of the invention
