LED display being so prompt attention, largely due to the high brightness of the display, but the purchase of higher brightness LED display is really better?
LED display with respect to the DLP, LCD splicing unique advantages being touted in the major cities, widely used in building advertising, subway stations, shopping malls display and other fields. Undoubtedly, prompting LED display so much attention, largely thanks to the display of high brightness, but the purchase of higher brightness LED display is really better?
As we all know, LED as a new light technology is based on light-emitting diodes, compared to traditional light sources with low energy consumption, high brightness of nature, the LED display is increasingly popular. In addition, many businesses in the LED screen products introduced to the user, often with "low-power, high-brightness" as a publicity stunt to users instill a "brightness higher the better, the more value" concept, Is this right ?
First, LED screen uses a self-luminous technology, as a light source, LED lamp beads will inevitably exist after a period of time appear light attenuation problems. To achieve high brightness, we need a larger drive current. However, in the strong current, the stability of the LED lamp will be reduced, and faster decay. That is, in fact, simply the pursuit of high-brightness LED screen at the expense of quality and longevity for the price, it is possible to input costs has not been recovered, the display can no longer service, resulting in a tremendous waste of resources.
In addition, now the world's urban light pollution have been very serious, many countries have even passed laws and regulations to strictly control outdoor lighting and display brightness. LED screen as many high brightness display technology in an almost become dominant outdoor display, but once in the evening, the screen is too bright it will become an invisible "contamination" in order to meet national environmental standards, reduce the brightness At the same time, it may cause extreme loss of gray, we can not guarantee a good screen display.

n addition to the above two points, the rising cost factors also need attention. Higher brightness, will inevitably lead to rising costs of the whole project, and whether the user really need such a high brightness is questionable, it may cause performance waste,
Therefore, the simple pursuit of high brightness, but is extremely harmful.
