What are the benefits of LED display screen brightness? LED display screens, as a medium of promotion, frequently appear in our daily lives, and the demand for maintenance and identification information relative to LED display screens has also increased. Below, we will discuss how to distinguish the brightness of LED display screens.
Firstly, let's understand what the brightness of an LED display screen is:
The brightness of LED light-emitting tubes refers to the intensity of the light emitted by the emitting body, known as light intensity, expressed in MCD. The luminous brightness of LED display screens is a comprehensive index that refers to the total luminous flux of all LED modules per unit volume and the illuminance at a certain distance.
LED display brightness: The unit of luminous intensity brightness per unit area in a given direction is cd/m2.
The brightness is directly proportional to the number of LEDs per unit area and the brightness of the LEDs themselves. The brightness of an LED is directly proportional to its driving current, but its lifespan is inversely proportional to the square of its current. Therefore, it is not advisable to excessively increase the driving current in pursuit of brightness. At the same point density, the brightness of an LED display screen depends on the material, packaging form, and size of the LED chip used. The larger the chip, the higher the brightness; On the contrary, the lower the brightness.
