With the continuous development and innovation of technology, the application of full color LED display screen is more and more widely available, since the 2008 Olympic Games in Beijing, shenzhen, manufacturer of LED full-color displays spring growth, followed by the corresponding parts and control system of full color LED display screen manufacturer also is increasing year by year.
Earlier years, LED full-color displays such as gold, but not for long, with more and more people join this industry, the market is a mess, a price drop down again, fewer and fewer profits since 2011 closed down several large LED display manufacturers. Although falling profits, but the prospects of full color LED display screen and a bright, market demand is very big, just people is higher and higher requirement for full color LED display screen, now the industry only constant innovation and improvement of product and full color LED display screen market to win the future.
At present, in this competitive market environment, although the visual effect of full color LED display screen is getting better and better, but the quality is worse and worse, some manufacturers for greater profits, electronic materials and accessories continuously improved and replace, shorten service life, failure rate greatly increased, lead to the user of LED full-color displays less comfortable to use, can't easily buy, manufacturer's sales people also become more and more difficult. How to solve this awkward situation? Has caused a lot of media attention.
Today, the majority of manufacturers for commercial profits, ignoring the many full-color LED display screen later use problems, such as the service life of LED lights and the failure frequency, power factor on the quality of the LED module, the influence of the control system of the whole screen visual impact, etc., of course, these problems can't entirely blame manufacturers, actually more factors is the users themselves, and cheap, and the pursuit of high-grade, and perfect, worse or middlemen and with single, basic profits were up, ought to shoot, of course, this is just a joke, zhou yu's sign up.
In such a flood of market environment, how to select qualified and durable full-color LED display screen? Let me share with you the LED full-color displays some of the parts selection, for himself to do technology, the understanding of the electronic materials comparison of full color LED display screen, hope to be able to give to the consumer and engaged in LED full-color displays some friends to help.

First of all, we come to know about the piece can be normal use full color LED display screen structure, it is by the

 LED unit module, the steel frame structure and enclosure, module power supply, power cables, signal lines, control card, computer and so on, the LED unit board respectively driven by LED lamp bead, PCB, IC, power supply and signal socket, suite, etc; Signal module wiring, cable connection control card; Control system are sending card and receiving card, computer, the computer asks to install independent video card, etc.

In full color LED display, LED lamp bead is one of the most critical material, it is a problem, other accessories again good also useless, so choose a good LED lamp bead manufacturers and users are extremely concerned about things, but many people don't know how to distinguish the pros and cons of lamp bead, general manufacturers have technical personnel with professional equipment and tools for experiments and testing, as the user how to test? Has two methods can detect, it is through the LED display control software testing, will be three colors and white balance effect of visual display, look to whether flower screen, color have off color, if there is no bright spots, dark spots, high bright, scan line test to see if there is ghosting (leakage) and window, and then play the video test view, general indoor full color LED display can be viewing Angle is 120 degrees from the horizontal and vertical, outdoor full-color LED display can view for level 100 degrees, 50 degrees vertically, if can be viewing Angle is too low, it is not qualified products; Second, if the user do not know how to check, please will module to peer other manufacturer for detecting technology, please help, confirm whether to buy bad products. When selecting a LED lamp bead, as far as possible choose brand LED lamp bead, wick choose strength strong company chip. LED encapsulation is also very important, LED encapsulation of life and the color, brightness of LED has a great influence.
The next us about full color LED display control system, it is also one of the most important accessories, equivalent to the human mind, without it, again good also some not bright LED, not display properly, the control system is mainly composed of computer data transmission to send card, again by sending card processing with cable transmission to receive card, receiving card again through the vent line will signal to the LED unit board to drive IC, and the driver IC control LED lights on and off, this is basic working principle. The choice of control card is also very important, I suggest it is best to use the user more control CARDS on the market, some unknown not mature control CARDS, cheap to use or not use less as far as possible, unless you would detection, then experiments confirmed that no problem for use, otherwise, if buy inferior control card, will greatly influence the visual effect, at the same time also can have effect on the lifespan of leds.

And then to the LED module, power supply, power supply, power supply quality will directly affect the life of the module, the power of the input voltage can be ac 110 v to 240 v, frequency 50 hz ~ 60 hz, the output is dc 5 v40a or 5 v60a, if it is a bad power supply, the output voltage is likely to be more than 5 v, the LED power supply voltage is 3 ~ 5 v, if beyond LED the load voltage, LED and IC will be destroyed. Suggest to buy famous brand power supply or market users more of a power supply as the preferred, the power of the high performance/price ratio, and the second is to consider, too cheap power generally will not be a good power supply, it is best not to pursue cheap, inferior power are easy to burn out, or output voltage instability, voltage is not pure, interference, had a great influence on full color LED display screen, at the same time also will increase the cost of maintenance. So do the full color LED display screen must consider later maintenance costs.
Looking back in the LED display industry over the years, can clearly feel the rapid development of the industry. It is because the development too fast, a lot of core technology also can't keep up with the rhythm. Full color LED display screen and there are many loopholes or shortcomings, first of all, it consumes, at least I think is power; The second is expensive, full-color LED display screen for ordinary people, currently still is a luxury; The third is heavy, especially outdoor full-color LED display screen. If you can design the light of some, then some energy saving, cheaper, more perfect it is. Of course, these technical improvements, in full color LED display screen manufacturers has been trying to innovation, I believe, with the constant innovation of technology and progress, full-color LED display screen will be more and more perfect, more and more popular with the consumers.
