Electronic Display Screen It is a display method that controls semiconductor light-emitting diodes, composed of tens of thousands to hundreds of thousands of semiconductor LED pixels arranged uniformly. Different materials can be used to produce LED pixels of various colors to display text, graphics, images, animations, market data, videos, and recorded signals on the screen. Currently, the most widely used colors are red, green, and yellow. The development of blue and pure green LEDs has reached a practical stage.

Introduction

LED electronic display screen: LED stands for light emitting diode, abbreviated as LED. It uses the electroluminescence principle of semiconductor P-N junctions to produce red, green, and blue colors. It is a semiconductor display device developed in the late 1960s; in the 1970s, with advances in semiconductor material synthesis technology, single crystal manufacturing technology, and P-N junction formation technology, the performance of LEDs in terms of color and brightness improved and quickly entered mass production and practical use.

In the 1980s, LEDs greatly improved in emission wavelength range and performance, and began to form flat panel display products, namely LED display screens. In the late 1980s, they rapidly developed worldwide as a new type of information display media. Using LED dot matrix modules or pixel units to form large-area display screens, they feature high reliability, long service life, strong environmental adaptability, high cost-performance ratio, and low operating costs. Within just over a decade, they quickly became the main product of flat panel displays and were widely applied in the information display field.

LED display screens are divided into text and graphic displays and video displays, both composed of LED matrix blocks. Text and graphic displays can synchronize with computers to show Chinese characters, English text, and graphics; video displays are controlled by microcomputers, combining text and images to broadcast various information in a real-time, synchronized, and clear manner. They can also display 2D and 3D animations, recordings, television, VCD programs, and live events.

LED Electronic Display Screen The display screen shows vivid colors with a strong sense of three-dimensionality, still like an oil painting, moving like a movie. It is widely used in stations, docks, airports, shopping malls, hospitals, hotels, banks, securities markets, construction markets, auction houses, industrial enterprise management, and other public places. Common specifications include PH10, PH12, PH16, PH20, PH25, and PH31.25.
