What is an LED display?

In theory, it is an active light-emitting display with LED as the light-emitting source. Using the unidirectional conductivity and electro-optical conversion characteristics of diodes, the display of information is realized. However, the current LED displays on the market are only liquid crystal displays with LEDs as the backlight source, which means that the role of LEDs is only lighting, and the information display is still liquid crystals. Personally think that the real LED display can only be realized after the bottleneck problem of excessive LED power is solved. Well, about three to five years.What is an LED display?

What is LED display.

LED is the English abbreviation of light-emitting diode, referred to as LED. It is a display method by controlling semiconductor light-emitting diodes. Its general appearance is composed of many light-emitting diodes, usually red, and the characters are displayed by the lights on and off. A display screen used to display various information such as text, graphics, images, animations, market quotations, videos, and video signals.

What is an LED display?

LED display, also known as electronic display or floating character screen. It is composed of LED dot matrix, which displays text, pictures, animations, and videos through the on and off of red or green lamp beads. It usually consists of a display module, a control system and a power supply system. The display module is composed of a dot matrix of LED lights, which is responsible for light-emitting display; the control system can display text, pictures, videos, etc. on the screen by controlling the on-off of the corresponding area; the power system is responsible for converting the input voltage and current into the required display screen. Voltage and current.

The LED display can display changing numbers, characters, graphics, and images; it can be used not only in indoor environments but also in outdoor environments, and has the incomparable advantages of projectors, video walls, and liquid crystal displays.

The reason why LED has been widely valued and developed rapidly is inseparable from its own advantages. When these advantages are summarized: low operating voltage, low power consumption, miniaturization, long life, shock resistance and stable performance, the development prospect of LED is extremely broad, and it is currently moving towards higher brightness, higher weather resistance, higher Luminous density, higher luminous uniformity, reliability, full color development.
