LED display aging test is a measure taken based on the characteristics of the product's failure rate curve, that is, the bathtub curve, in order to improve the reliability of the product. If there is a question about frequency, it is not constant current. AC or pulsating current sources can be designed to have a constant effective value, but such power sources cannot be called "constant current sources." Constant current aging is the most consistent with the working characteristics of LED current and is the most scientific LED aging method; over-current impact aging is also the latest aging method adopted by manufacturers. This type of aging is carried out by using a constant current source with adjustable frequency and adjustable current. , in order to determine the quality and life expectancy of LEDs in a short period of time, and to pick out many hidden dangers of LEDs that cannot be picked out by conventional aging. LED display screens can improve performance after aging and contribute to performance stability in later use. A constant current source means that the current is constant at any time.

Simply speaking, the LED display screen is composed of several display units (unit display panels or unit display boxes) that can be combined and spliced, plus a set of appropriate controllers (main control board or control system). Therefore, display panels (or unit boxes) of various specifications and controllers with different control technologies can form many kinds of LED displays to meet the needs of different environments and different display requirements.

The smaller the point density and the gradient of pixel density, the more information capacity can be supplemented per unit instantaneously, and the distance suitable for viewing is closer. On the contrary, the distance suitable for viewing is further away. We need to combine our allocation and reconstruction effects to make the selection. As for the LED display screen, the smaller the pixels, the better. This is inevitable!

There are two basic prerequisites for achieving high-definition display on a full-color LED display. One is that the video source must be high-definition, and the other is that your LED display must support high-definition display.
