There must be many small partners who want to know more about the types of LED screens, so today I have collected some knowledge about the types of LED screens to share with you, I hope you will like it.
The LED display is classified according to the application site
Electronic banners, small-pitch LED displays, stage rental displays, etc. all belong to LED electronic displays. So, how is it classified? According to different application places, LED electronic displays can be divided into indoor LED displays and There are two types of outdoor LED displays.
Indoor LED display
It is mainly used indoors. In the production process, the light-emitting crystal grains are first made into dot matrix modules (or digital tubes), and then the modules are spliced into a display unit board of a certain size. According to user requirements, the display unit board is used as the basic unit for splicing. into the size required by the user.
According to the size of the pixel, the resolution of indoor LED display is generally relatively small, divided into Ф2, Ф3, Ф3.75, Ф4.8, Ф5, Ф8, Ф10, etc.
Tip: Ф means diameter
Outdoor LED display
It is mainly used outdoors. In the production process, the first step is to encapsulate the light-emitting crystal grains into a single light-emitting diode, which is called a single lamp. The single lamp used to make an outdoor LED display generally adopts a reflector with a concentrating effect to improve the performance. Brightness; multiple LED single lamps are then packaged into a single pixel tube or pixel module, and the pixel tube or pixel module forms a dot-matrix display unit box.
According to user needs and display applications, a display unit box is used. The volume is the size required for the composition of the basic unit. The box should be sealed in design to achieve the purpose of waterproof and anti-fog, so that it can adapt to the outdoor environment.
According to the size of the pixel, the outdoor LED display is divided into *11, Ф14, *16, *19, *21, *26, Ф36 and other specifications.
The LED display is classified according to the base color
According to the color of the LED used, the LED display can be divided into three types: single primary color, dual primary color and full color.
1. Single primary color LED display
Each pixel has only one color, and most of them use red and white, because red and white have higher luminous efficiency and can obtain higher brightness. As for we sometimes see green and yellow monochrome displays, it is because through superimposed and mixed.
To be precise, they are actually dual-color LED displays, which only display one color, so they can use green or mixed colors, that is, some use red, some use green, and some use yellow.
2. Dual primary color LED display
Each pixel has two primary colors, red and green, and yellow can be superimposed. In the case of grayscale control, a maximum of 65535 colors can be combined through the change of different grayscales of red and green. Most of the traffic signs we usually see use dual-color LED displays to display information
3. Full color LED display
Also known as three primary colors, each pixel has three primary colors of red, green and blue. Under the condition of 255 grayscale control, through the change of different grayscales of red, green and blue, the colors of nature can be well restored, and 16777216 kinds of colors can be combined. color.
LED electronic display screen can be divided into four types: strip screen, graphic screen, video screen and digital screen according to the functions of the screen.
3. LED strip screen
This type of display screen is mainly used to display text. It has its own 16X16 or 24X24 dot matrix font library, which can work independently. The remote control can be used to input Chinese characters. The electronic banner can also be used online with a computer to send information through the computer. Can work offline. Mainly because this type of LED subtitle display products are mostly made into strips that can display electronic subtitles, so they are called strip screens, and the full name is: LED strip-shaped display screens.
4. LED graphic screen
This type of display is mainly used to display text and graphics, generally without grayscale control. It enters information by communicating with a computer. Compared with the bar screen, the advantage of the graphic screen is that the displayed fonts are rich and the graphics can be displayed. Compared with the video screen, the biggest advantage of the graphic LED display is that a computer can control multiple screens, and can be removed machine display.
5. Video LED display
This type of display screen has a one-to-one mapping relationship with the control computer monitor pixels, and has grayscale control, so its expressiveness is extremely rich. It is equipped with a multimedia card, and the video screen can also play video signals. The video LED display has good openness and reflects the display of the computer monitor in real time.
Such display screens usually need to be used in conjunction with video control playback boxes or video controllers. The forms that can be displayed have become more colorful.
6. LED digital screen
Digital screen is the cheapest LED display, widely used in bank exchange rate, interest rate display, hotel seafood price list, room price list, etc. In most cases, a strip screen is installed on the digital screen to make up for the deficiency that the digital screen cannot display text.
And doing so is more cost-effective than directly using a full-color LED display, so the scope of application is quite extensive.
7. LED hybrid screen
That is, dot matrix digital mixed display, it is most used for stock market display. Both numbers and text can be displayed, which is very important for people who need to display and view information.
The above is an introduction to “What are the classifications of LED displays?” Do you understand? As China’s LED display industry continues to increase, in the streets and lanes of major cities, LED large-screen displays have gradually increased, and people’s consumption The level is also increasing day by day, LED lighting has been gradually applied to the daily life of the family, LED electronic display not only enhances the image of the city, but also enriches people’s cultural life.
