LED originated in the 1970s, was originally used merely as alphanumeric display, with the increasing advances in the development of society and technology, LED screen gradually become a text, image, video, video signals to a display for equipment and other kinds of information. Nowadays, LED has been widely used in automotive, manufacturing, industry, communications industry, consumer goods industries, it has been able to rage, it has a direct relationship to their advantage. Is well known, LED is a high safety, stable performance, smaller power consumption, long life cycle, higher brightness electronic device. Compared with the past, today's higher LED luminous density, ability to adapt to different scenarios of stronger, higher luminous uniformity, more stable and reliable, thanks to the use of static scanning technology in the LED to a large extent . Admittedly, the many advantages of LED, full brightness, but it is not a perfect device, there are also some shortcomings, for example: Although the LED able to resist rain and snow, but it will seriously affect people's visual effects, if people remain near LED screen from viewing the content is extremely susceptible to symptoms of vertigo. Therefore, in the future development, LED screen manufacturers should be improved for its shortcomings, rather than to seek high brightness.
