LED display as a security surveillance display field of heavy soldiers, the market development of a direct impact on the security industry direction. Outdoor LED LED industry is the development of intelligent traffic has an unparalleled advantage, is the LED field of important development direction. With the unprecedented prosperity of LED technology, LED display products concern, widely used in commercial advertising, live broadcast, traffic induction, stage interpretation and other fields.
LED display four major advantages
In the outdoor advertising market, LED large-screen advertising and targeted consumer groups with strong, visual impact of strong performance, flexible advertising updates, thousands of low-cost, high coverage of the advantages of the audience has become an important outdoor advertising media.
Compared with the LCD screen machine, LED display advantage is mainly reflected in the following points:
1, area ductility, LCD area is difficult to achieve seamless stitching, LED display can be extended, and to achieve seamless stitching.
2, LCD plasma screen luminous flux attenuation soon, the general operation of a year and a half or so, you need to replace, but the LED display under the same operating conditions for at least five years no problem.
3, LED brush screen machine can use interactive technology, enhance the brush machine as advertising media and advertising audience interaction, such as custom touch screen, to achieve cloud technology broadcast control management.
4, in the display, LED display high brightness, wide viewing angle and good color reproduction capability is better than the LCD screen. LED brush screen machine is generally used for airports, shopping malls, hotels, high-speed rail, subway, cinema, exhibition, office, etc., the target customer spending power, with great advertising value.
LED display optional reference
LED production process requirements are high, not all enterprises have the appropriate strength, resulting in the quality of the LED display on the market varies greatly. LED lighting system design requirements are very precise, LED tube and condenser cups are very small size, the relative position of the two with a higher demand, a small deviation, the light reaches the stage position will be a big gap. In order to meet the design requirements, the process requirements of manufacturers will be a large number of LED tube consistency screening, taking into account the LED tube in the circuit board on the thickness of the slurry gap, manufacturers will use automated laser welding process.
In addition, the heat problem directly affects the LED luminous efficiency. At present, high-quality LED display from the design and process to solve the heat problem, you can have more than 30,000 hours of life, but the design or poor technology LED display may be only a few thousand hours or even shorter life.
Professional development, design, strict production management, enterprises from the components, the selection of materials, from the advanced automated operation machinery to the production process of strict quality control (including the aging of the middle parts processing), each link affects the LED display Screen quality.
