1、 LED displays are classified according to the application site
1、 LED displays are classified according to the application siteElectronic banner, electronic subtitle and led subtitle belong to LED electronic display screen. So, how does it classify? According to different application places, LED electronic display can be divided into indoor LED display and outdoor LED display1. Indoor LED displayIt is mainly used indoors. In the manufacturing process, first, the luminous grains are made into lattice modules (or digital tubes), and then the modules are spliced into a display unit board of a certain size. According to the user's requirements, the display unit board is taken as the basic unit and spliced into the size required by the user.

What kinds of LED screen?

the design of the display unit board is introducedAccording to the size of pixels.
indoor LED display is divided into Ф 2、 Ф 3、 Ф 3.75、 Ф 4.8、 Ф 5、 Ф 8、 Ф
10, etc2. Outdoor LED displayIt is mainly used outdoors.
in the production process, the first step is to package the light-emitting grains into a single LED, which is called a single lamp. The single lamp used for making outdoor LED display generally uses a reflective cup with a concentrating effect to improve the brightness; Then, a single LED lamp is packaged into a single pixel tube or pixel module, and the pixel tube or pixel module is used to form a dot matrix display unit box. According to the user's needs and display application sites, a 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 antifogging, so as to adapt to the outdoor environment.
the design of the box should be carried out according to the user's needs and display application sites3. According to the size of pixels.
outdoor LED displays are divided into * 11, * 11, and * 11 Ф 14、*16、*19、*21、*26、 Ф 36 and other specifications.
the results show that the2. LED displays are classified according to primary colorsAccording to the color of the LED used.
the LED display can be divided into three types: single primary color, double primary color and full color.
the color of the LED display can be divided into three types1. Single primary color LED displayThere is only one color for each pixel.
most of the pixels use red, because red has high luminous efficiency and can obtain higher brightness. It can also use green, or mixed color, that is, some use red, some use green, and some use yellow.
the color of each pixel is redDual primary color LED displayEach pixel has two basic colors of red and green.
yellow can be superimposed, and 65535 colors can be combined at most through the change of different gray levels of red and green under the condition of gray control.
in this paper, the color of yellow can be superimposed2. Full color LED displayIt is also called three primary colors.
each pixel has three primary colors, red, green and blue. Under the condition of gray control, through the change of different gray levels of red, green and blue, the natural colors can be well restored, and 16777216 colors can be combined.
in this way, the natural colors can be restoredThe LED electronic display screen can be divided into four types according to the function of the screen.
the LED display screen can be divided into bar screen, graphic screen, video screen and digital screen3. LED bar screenThis kind of display screen is mainly used to display text.
it has its own 16x16 or 24x24 dot matrix font library, which can work independently. You can input Chinese characters with the remote control, and the electronic banner can also be used online with the computer to send information through the computer.
it can work offline.
because this kind of LED subtitles are mostly made into strips, which can display electronic subtitles.
so it is called strip screen.
this kind of LED subtitles can display electronic subtitles4. LED graphic screenThis kind of display screen is mainly used to display text and graphics.
generally, there is no gray control.
it inputs information through communication with computer.
compared with bar screen.
the advantage of graphic screen is that it can display rich font and graphics. Compared with video screen, the biggest advantage of graphic LED display screen is that a computer can control multiple screens,And it can be displayed offline.
the5. Video LED displayThis kind of display screen pixel and the control computer monitor pixel present a one-to-one mapping relationship.
it has gray control, so its expressive power is extremely rich. With the configuration of multimedia card, the video screen can also play video signals.
the video LED display has good openness.
it can reflect the display of the computer monitor in real time.
the display of the computer monitor is very rich6. LED digital screenDigital screen is the cheapest LED display screen.
it is widely used in the display of bank exchange rate, interest rate, hotel seafood price list, room price list, etc.
in most cases,
bar screen is added on the digital screen to make up for the lack of text display on the digital screen.
the digital screen can not display text7. Led hybrid screenThat is, dot matrix digital mixed display.
it is most widely used in the display of securities market.
this paper introduces the application of dot matrix digital mixed displayThe above introduces the classification of LED displays.
do you know about it? With the development of China's LED display industry increasing, LED large screen displays are gradually increasing in the streets of major cities, and people's consumption level is also growing. LED lighting has been gradually applied to the daily life of families. LED electronic displays not only enhance the image of the city, but also enhance the image of the city, Led also enriches people's cultural life.

hello.
indoor two-color LED display screen is widely used in finance, posts and telecommunications, telecommunications, electric power, hospitals, troops, public security, shopping malls, finance, taxation and other departments and places.
this paper introduces the development of LED display screen in ChinaOutdoor dual color LED display screen is widely used in square, commercial center, highway and other densely populated outdoor places.
it has the characteristics of high brightness, all-weather display, flexible and convenient modification of display content and mode, powerful display function, low power consumption, long service life, etc.
it has been widely used in square, commercial center, highway and other densely populated outdoor placesIndoor full-color LED display is also known as three primary colors, which is the smallest display unit composed of red, green and blue primary colors.
it is consistent with the working principle of computer display.
it can truly restore colors, and red, green, blue and 256 gray levels can form 16.7M (million) colors.
it can display dynamic images with rich colors in real time.
it can display dynamic images in real timeThe outdoor full-color LED display is also known as three primary colors, which is the smallest display unit composed of red, green and blue primary colors.
it is consistent with the working principle of computer display.
it can truly restore the colors, red, green, blue and 256 gray levels to form 16.7M (million) colors.
