What kinds of LED screens are there?

Firstly, the LED display screen is divided into electronic banners, electronic subtitles and LED subtitles according to the application places. So, how is it classified? According to different application places, LED electronic display screen can be divided into indoor LED display screen and outdoor LED display screen. \x0d\ 1, indoor LED display \x0d\ are mainly used indoors. In the manufacturing process, firstly, the light-emitting crystal grains are made into lattice modules (or digital tubes), and then the modules are spliced into a display unit board with a certain size, and the display unit board is spliced into the size required by users according to their requirements. \x0d\ Indoor LED display screen is divided into Ф 2, Ф 3, Ф 3.75, Ф 4.8, Ф 5, Ф 8, Ф10 and so on according to pixel size. \x0d\ 2。 Outdoor LED display screen \x0d\ is mainly used outdoors. In the manufacturing process, firstly, the light-emitting die is packaged into a single light-emitting diode, which is called a single lamp. Generally, the single lamp used to make outdoor LED display screen adopts reflective cup with condensing function to improve brightness; Then, a plurality of LED single lamps are packaged into a single pixel tube or pixel module, and a dot matrix display unit box is formed by the pixel tube or pixel module. According to the needs of users and display application places, the display unit box is used as the basic unit to form the required size. The box should be sealed in design to achieve the purpose of waterproof and fog prevention, and adapt to the outdoor environment. \x0d\ 3。 Outdoor LED display screen is divided into * 1 1, Ф14, * 16, * 19, *2 1, *26, Ф 36 and other specifications according to pixel size. \x0d\ II。 LED display screens are classified by primary colors \x0d\ According to the colors of LEDs used, LED display screens can be divided into three types: single primary color, double primary color and full color. \x0d\ 1。 Monochrome LED display screen \x0d\ each pixel has only one color, most of which is red. Because red has high luminous efficiency, it can obtain higher brightness, green or mixed colors, that is, some are red, some are green and some are yellow. \x0d\ Dual primary color LED display \x0d\ Each pixel has two primary colors, red and green, which can be superimposed into yellow. In the case of gray scale control, as many as 65535 colors can be combined by changing the different gray scales of red and green. \x0d\ 2。 Full-color LED display screen \x0d\ is also called tricolor, and each pixel has three primary colors of red, green and blue. In the case of gray scale control, the colors of nature can be well restored by changing the different gray scales of red, green and blue, and 167772 16 colors can be combined. \x0d\ LED electronic display screen can be divided into four types according to screen function: bar screen, graphic screen, video screen and digital screen. \x0d\ 3。 LED bar screen \x0d\ This display screen is mainly used to display characters. With 16X 16 or 24X24 dot matrix font, it can work independently. Chinese characters can be input remotely, and electronic banners can also be used online with computers to send messages. You can work offline. Because this kind of LED subtitles are mostly made into strips to display electronic subtitles, it is called strip screen. \x0d\ 4。 LED graphic screen \x0d\ This display screen is mainly used to display text and graphics, generally without gray control. It inputs information by communicating with the computer. Compared with the bar screen, the graphic screen has the advantage of displaying a variety of fonts and can display graphics. Compared with video screen, the biggest advantage of graphic LED display screen is that one computer can control multiple screens and display them offline. \x0d\ 5。 Video LED display screen \x0d\ This kind of display screen has a one-to-one mapping relationship with the pixels controlling the computer display, which is controlled by gray scale, so its expressive force is extremely rich. With the multimedia card, the video screen can also play video signals. Video LED display screen has good openness and can reflect the display of computer monitor in real time. \x0d\ 6。 LED digital screen \x0d\ Digital screen is the cheapest LED display screen, which is widely used in bank exchange rate, interest rate display, hotel seafood price list, room price list and so on. In most cases, a bar screen is installed on the digital screen to make up for the lack of text displayed on the digital screen. \x0d\ 7。 LED mixed screen \ x0d \ is a dot matrix digital mixed screen, which is most commonly used to display the stock market. \ x0d \ What are the classifications of LED displays? You got it? With the development of LED display industry in China, LED large-screen displays are gradually increasing in the streets of major cities, and people's consumption level is also constantly improving. LED lighting has been gradually applied to the daily life of families. LED electronic display not only enhances the image of the city, but also enriches people's cultural life.
