As we all know, LED, as a new type of light-emitting technology, is based on light-emitting diodes. The characteristics of low energy consumption and high brightness are inherent, so LED displays are increasingly popular. But is the LED display really the higher the brightness, the better and the higher the value?
LED screen adopts self luminous technology. As a light source, LED lamp beads will inevitably have the problem of brightness attenuation after a period of use. To achieve high brightness, greater drive current is required. However, under strong current, the stability of LED lamp beads will be reduced, and the attenuation will be faster. In other words, the pure pursuit of high brightness is at the expense of the image quality and life of the LED screen.
The small pitch LED screen is widely used in indoor use scenes such as company meetings and classes because it is suitable for viewing closer. From outdoor to indoor applications, although the small pitch LED has shortened the viewing distance of these users, when they continuously focus on the screen for a long time in the dark indoor environment, the continuous high brightness of LED may cause dazzling, fatigue and pain, and even irreversible vision damage to the human eyes. However, some indoor LED display products on the market only have "low brightness and low gray". When users reduce the brightness of the display screen, the overall definition will be greatly reduced with the loss of image gray. The small spacing LED screen supporting "low brightness and high gray" can effectively solve this problem encountered in indoor applications.
Different from the "low brightness and low gray" characteristics of conventional LED display, small pitch LEDs supporting "low brightness and high gray" can achieve high definition at low brightness through high brush chip. When the brightness range is between 100 cd/㎡ and 300 cd/㎡, there is almost no loss of gray scale of the image, that is, it is difficult for the human eye to detect the obvious gray scale loss, and the close look is more comfortable without hurting the eyes. "Low brightness and high gray" can be said to be the first normative factor for small pitch LED products entering the room, and also an important part to distinguish the quality of small pitch products.
In addition to reasonable control of indoor brightness, some competitive user level indoor products have been committed to improving user experience for a long time. With the development of small pitch LED in the field of indoor display application, more functions need to be explored in the future.
