LED displays can be seen everywhere in our lives, especially when walking on the streets of cities, we always see led displays on tall buildings in the streets. But many of us don't know much about this ubiquitous object. Then, today I will introduce to you the LED display screen and its construction attention elements.
LED display introduction
LED is LightEmittingDiode, English abbreviation light-emitting diode, referred to as LED. This is a method of displaying by controlling semiconductor light-emitting diodes. Its gen
Eral appearance is composed of many generally red light-emitting diodes, and characters are displayed through the illumination of lights. The display screen used to display text, graphics, images, animation, market prices, video, and various information, such as video signals , the content can be replaced at any time, and all components are modular displays. The traditional LED display is usually composed of a display module. It is composed of a control system and a power system. The display module is composed of a dot matrix composed of LED lights, which is responsible for lighting display; the control system can display the text on the screen by controlling the lighting of the corresponding area. .Photos, videos and other content, solid color and two-color screens are mainly used to play text, and full-color screens are usually used to play animations; the power system is responsible for converting the input voltage and current into the voltage and current required by the display. Diversification of product structure: From the perspective of product application fields, the variety of LED display products in the field of information services will be more abundant, such as public transportation. .Parking lot. Catering. Comprehensive services, such as hospitals; from the perspective of product form, new products such as special-shaped Ultra-thin, high-definition will be more perfect and more suitable for the individual needs of users.
led display construction technology
1. LED detection display installation site survey
