What is an LED display?
Light Emitting Diode, the abbreviation of LED, referred to as LED. The LED electronic display is composed of tens of thousands - hundreds of thousands of semiconductor light-emitting diode pixels, which is a display method for controlling semiconductor light-emitting diodes for displaying text, graphics, images, animations, quotes, videos. Display screen for various information such as video signals. Different colors of LED pixels can be made with different materials. Currently the most widely used are red, green and yellow. The development of blue and pure green LEDs has reached a practical stage. The LED display can display changing numbers, texts and graphic images; it can be used not only in indoor environments but also in outdoor environments, and has the advantages that projectors, TV walls, and liquid crystal displays cannot match. The LED display is divided into a graphic display and a video display, both of which are composed of LED matrix blocks. The graphic display can display Chinese characters, English text and graphics synchronously with the computer; the video display screen is controlled by a microcomputer, and the pictures and images are displayed together, and various information can be played in real-time, synchronous and clear information dissemination mode, and the second display can also be displayed. Dimensions, 3D animation, video, TV, VCD shows and live live. The LED display screen has bright colors, strong stereoscopic effect, and is as static as oil painting. It is widely used in stations, terminals, airports, shopping malls, hospitals, hotels, banks, securities markets, construction markets, auction houses, industrial enterprises and Other public places. The reason why LED has been widely recognized and developed rapidly is inseparable from its own advantages. These advantages are summarized as follows: high brightness, low operating voltage, low power consumption, miniaturization, long life, shock resistance and stable performance. The development prospects of LED are extremely broad, and are currently developing towards higher brightness, higher weather resistance, higher luminous density, higher uniformity of illumination, reliability, and full color.
