Many people tend to confuse LCD screens and LED screens
What is the difference between LCD and LED screens? Let Xiaoyou popularize it for everyone today.
Led screen: also called electronic display or floating text screen. It is composed of LED dot matrix and LED PC panel. It displays text, pictures, animations, and videos by turning on and off red, blue, and green LED lights. The content can be changed at any time, and each component is a modular display device.
Traditional LED screens usually consist of display modules, control systems, and power systems. The display module is composed of a dot matrix composed of LED lights, which is responsible for luminous display; the control system can display text, pictures, videos, etc. on the screen by controlling the on and off of the corresponding areas. The monochrome and dual-color screens are mainly used to play text, and the full-color screen is mainly 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.
Generally used in auditoriums, outdoor large advertising screens, etc.
LCD screens are mainly used for mobile phones, medical equipment, etc. LCD displays use two polarized materials, with a liquid crystal solution between them. When an electric current passes through the liquid, it rearranges the crystals so that light cannot pass through them. Therefore, each crystal acts like a shutter, allowing light to pass through but also blocking it.
The above are some of Xiaoyou’s own views on the differences between LCD and LED screens. Generally speaking, LED screens are better, but the price of LED is relatively higher. However, some occasions are suitable for LCD screens, so it is defined according to the environment and price.
