Product low power consumption, long life, high reliability. (4) to keep pace with the computer, the computer screen can see both the LED display shows, not tight real-time, three-dimensional animation and life; (5) The super multimedia, graphic re-production broadcasting system, by improving WINDOWS friendly interface, support program production and multimedia playback. (7) supports a variety of computer networking standard interface, easy networking, which enables remote real-time control. (8) position adjustable screen map display, and can easily display a random selection of screen size, and can open multiple windows with the PIP function. (9) The non-linear calibration technology, dynamic cache technology, multimedia technology, network technology, video synchronization technology, supporting computer network interface can be connected to TV, VCD, DVD, VCR and video cameras, scanners, digital cameras, broadcast advertising programs, information. (10) high gray level, high resolution, picture detail and beautiful. First, in the household screen, two outdoor atmospheres, and multi-purpose indoor SMD chip, used for in-line outdoor lights. After clear application environment is to be clear, do much dot pitch, a different point spacing suitable viewing distance is not the same. Then, is the need to screen the area. Display is divided into: monochrome, dual-color, full color. Must be according to your needs, not necessarily the best fit, fit is optimal. Second, life 100,000 hours LED materials manufacturers technical information issued indicating life LED light is ideal state 1 O million hours. Ideal means in the laboratory under constant voltage constant current state led to the luminous body does not emit light from the light time, 1 O ten thousand hours equivalent to 11 years. A bucket of water storage is determined by how much the lowest board, LED display currently used for civilian-level device, the service life of no more than 8 years. As a function of the display is to watch, when the display is lit only at night in order to see that it can not be qualified, with use value. A car can start 15 years, if idle for three years while in retirement. Environment and methods used a great influence on the life of the product. Third, the software and control hardware display industry, a common problem of Chinese enterprises widespread - not only the production of research and development. The general businesses do not have the software research and development capabilities, LED screen software basically Four professional developers to develop production, low price depends on performance and not simply look at the price. Because the current market price of a mess, a lot of quotes even our production costs are not enough, which explains the use of the material in question but clearance and other possible, so that customers buy products, we must understand the situation of the enterprise. the cost of a large screen, we can not as long as the cheaper products, or you will not get a real role. V. gray gradation as dual-color and full-color display is an important indicator. Currently on the market flooded with many one six and 64 gray-scale display posing as 256 gray levels. Controlling costs only 256 gray control 1/5. The easiest way is to play a more vigorous exercise scenes VCD View is able to see clearly on the LED display. Sixth, we should buy the best of everything from the purchasing power needed to meet the needs and have some advance. Blind pursuit will waste a lot of money to buy his own unwanted features.
