Analysis of why outdoor LED display advertising media favored by

LED display as the darling of the field security monitoring display, market development directly affects the security industry direction. Outdoor LED advantage is the development of LED industry has unparalleled intelligent transportation, LED display is an important development direction of the field. With the unprecedented prosperity of LED technology, LED screen products concern, widely used in commercial advertising, live broadcast, traffic guidance, stage interpretation of other fields.
LED display four advantages
In the outdoor advertising market, LED screen advertising due to the target consumer groups have relevance strong visual impact and strong performance, advertising updates flexible, low cost per thousand audience Reach Higher huge advantage, has become an important outdoor advertising communication media. Compared with LCD scraper machines, LED display advantages in the following points:

1, an area of ​​ductility, LCD large area is difficult to achieve seamless, LED display can be arbitrarily extended and seamless splicing.
2, LCD plasma screen flux decay quickly, usually run one and a half or so, they need to be replaced, but the LED display under the same operating conditions of at least five years, no problem.
3, LED scraper machine can use interactive technology to enhance scraper machine as an interactive advertising medium between the audience and advertising, such as custom touch screen, to achieve cloud broadcast control management.
4, in terms of display, LED display of high brightness, wide viewing angles and good color reproduction is superior to LCD screens. LED scraper machines are generally used in airports, shopping malls, hotels, high-speed rail, subway, theater, exhibitions, offices and other target customers spending power, with great advertising value.
LED display optional reference
High LED production process requirements, not all companies have the appropriate strength, resulting in quality LED display on the market varies greatly. LED lighting design requires very sophisticated optical system, LED tube and a condenser cup of very small size, the higher the relative position with the requirements of both, a little deviation, the position of the light reaches the stage there will be a big gap. In order to meet the design requirements, process demanding manufacturers have a large number of LED tube consistency of screening, taking into account the gap between the LED circuit board solder paste thickness produced, manufacturers will use automated laser welding process.
In addition, the heat issues directly affect the LED luminous efficiency. Currently quality LED display and process from the design to solve the heat problem, there may be more than thirty thousand hours of life, but poor design or technology of LED display may only a few thousand hours or even shorter lifespan. Professional development, design, strict management, enterprises from the components, the choice of material, from advanced automation machinery to strict quality control of the production process (including aging intermediate member), each link affects the LED display quality screen.
LED display to identify the good and bad
1. surface flatness flatness LED screen to within ± 1mm, to ensure that the displayed image is not distorted, partial raised or recessed will lead to the display viewing angle of dead ends. The quality of flatness is determined mainly by the production process.
2. brightness and luminance viewing angle indoor full color To 800cd / m2 or more, and full-color outdoor brightness To 1500cd / m2 or more, to ensure the normal operation of the display, or because the brightness is too low and can not see image display. The size of the brightness of the LED die is good or bad decision. How much the size of the audience display viewing angle directly depends, therefore the bigger the better. Mainly by the size of the viewing angle of the die package to decide.
3. The balance effect balance effect is one of the most important indicators of the display. Chromatics taken in red, green and blue ratio of 1: 4.6: 0.16 pure white will show, if the actual proportion of any deviation occurs the white balance bias, generally pay attention to whether there is bluish white, yellow green phenomenon. White balance is mainly determined by the quality of the display control system, die for the reduction of color also have an impact.
4. The reduction of color color reduction refers to the color display of color reduction, the display shows both to be highly consistent with the source of the color, so as to ensure realistic images.
5. Have mosaic, dead phenomenon refers mosaic appear on the display lit or normally black small squares, both modules necrosis, connector quality is mainly used for the display, but off. Dead point is steady appear on the LED display or normally black single point, how much good or bad from the die to determine the dead point.

6. Have color color refers to the existence of obvious color difference between adjacent modules, transition colors in module units, the color phenomenon is mainly caused by the control system is poor, gray level is not high, scanning lower frequency caused.
