Description
Technical field
The invention belongs to LED electronics applications field, and in particular to a kind of liftable LED display.
Background technology
LED technology is a 21 century high-tech technology with fastest developing speed, with and conventional industries combination, LED technology
Huge market application potential is shown, high-end LED product also increasingly has the market competitiveness.With various countries' city advertisement industry
Development, the application of LED display increasingly popularizes, particularly the LED display of high definition super large, in various large organizations or work
Disorder of internal organs is even more and embodies powerful demand force.But, it is more on the definition, size and range of movement in LED display
Be simply confined to fixed position compared with small area, this undoubtedly limits the range of application of LED product, also counteracts that LED markets
Further development.So, LED industry just seems to the demand of a kind of high definition, super large, the Telescopic LED display screen of automatization
It is increasingly urgent.
To China led display screens industry while scale development, product technology is weeded out the old and bring forth the new, and is always maintained at more advanced
Level.Possess state's advanced levels such as the color video control technology of 16 grades of gray scales 256 and wireless remote control of maturation the beginning of the nineties
Technology, in recent years in full color led display screen, 256 grades of greyscale video control technologies, clusters without warp control, multistage group control technology
Etc. aspect have the domestic advanced, technology that reaches international standards and product to occur；Led display screens control special large-scale integrated electricity
Road also by domestic enterprise's Development and Production and has been applied.But compared with advanced foreign technology, still there are Some Key Technologies
Have much room for improvement：
One is luminance shortage problem.The main advantage of LED display is the superpower adaptation of the outdoor environment to complicating more
The characteristics of power, outdoor environment, requires that LED display will can ensure in fine day, cloudy day, sleety weather, remote, various visual angles
Enough brightness carrys out transmission information, therefore brightness is particularly important, and due to LED luminance deficiency so that at present LED is in illuminating industry
In can only stooge, be mainly used in decoration, this is even more a huge challenge for the integrated use of LEDs up to ten thousand.
Two is LED aberration problems.Single led application, is substantially absent from aberration problem, but numerous LED is carried out comprehensive
Close if using, aberration problem will show especially out.Although prior art is improving this problem, due to domestic technique and production
Level is limited, and in same batch LED in same zone difference is yet suffered from, and this species diversity is difficult to escape the fastidious of naked eyes, from
And it is difficult to ensure that the color reducibility and verisimilitude of LED display.
Three is LED display control chips.The very color high-resolution LED electronic display of super large is used as a kind of new display matchmaker
Body, with its clearly image and high performance ability to play, is more and more subject to people's attention.And for LED display unit comes
Say, three-primary color LED tube core is its core devices, therefore the little and good tube of high quality of luminous intensity concordance should be differed using wavelength
Core, and this kind of technology is mainly rested in world-famous major company's handss, such as Japanese Ya companies.Four is thermal diffusivity.Due to
Outdoor ambient temperature change is very big, itself certain heat is produced when in addition display screen works, if ambient temperature is too high
Radiate in addition again bad, it is abnormal to will likely result in integrated circuit operation, or even is burned out, so that display system cannot be just
Often work.
With the development of economic globalization, intellectual property is increasingly becoming the focus of international competition, and intellectual property is generally included
Patent, trade mark and copyright, with region, the patent right in such as U.S. can only possess right in the U.S..Meanwhile, intellectual property
It is the strategic resource of country and enterprise-essential.On June 5th, 2008, China《State intellectual property right strategy outline》It is formal to promulgate real
Apply, proposition must conscientiously strengthen Intellectual Property using intellectual property strategy as national grand strategy.In LED field, patent
Lawsuit rises one after another, and one trouble comes after another；And the patented technology of LED industry middle and upper reaches, it is concentrated mainly on foreign enterprise handss
In, that is to say, that foreign enterprise has held patent strategy initiative.LED industry market extensively, has a bright future；And China LED
Industry starting is relatively later, but development speed is swift and violent, and Intellectual Property Rights Issues are increasingly becoming the bottleneck that industry is quickly caught up with and surpassed, such as
What adapts to as early as possible international game rule, Intellectual Property is strengthened conscientiously, realizes that patent is broken out of an encirclement, and is that China's LED industry must be solved
Problem certainly.
The diversified development of outdoor display screen so that increasing occasion has been respectively mounted large LED display screen, but,
In some large buildings or the LED display of architectural setting, in the situation for considering many factors such as Radix Saposhnikoviae, printing opacity, attractive in appearance
Under, also with certain limitation.
The content of the invention
The technical problem to be solved is：A kind of liftable LED display is provided, outdoor display screen tool is solved
There is the circumscribed problem of installation.
The present invention is employed the following technical solutions to solve above-mentioned technical problem：
