The following is the relevant information collected by LED display brand manufacturer lianchengfa group, hoping to help you1、 Classification by primary color:Monochrome LED displayMonochrome LED display has only one color, most of which are fashionable blue or green backlight. Of course, there are other uncommon single colors, such as red, yellow and so on.
monochrome LED display mostly uses red.
because red has high luminous efficiency, it can obtain higher brightness, green or mixed color, That is to say, one part is red, one part is green and one part is yellowDual color LED displayThe two-color LED display is a LED display made by putting red and green LEDs together as one pixel.

What are the categories and uses of LED display?

each pixel has two basic colors of red and green.
yellow can be superimposed. Under the condition of gray control, 65535 colors can be combined through the change of different gray levels of red and green.
Full color LED displayThe full-color LED display screen is composed of red, green and blue LED tubes as a pixel LED display screen.
the full-color LED display screen is also called three primary colors.
each pixel has three primary colors of 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.
the full-color LED display screen has three primary colors of red, green and blue2、 According to the use environment:Indoor LED displayThe indoor LED display screen is mainly used indoors.
in the production process, first of all, the light-emitting grains are made into lattice modules (or digital tubes), and then the modules are spliced into a display unit board of a certain size,The display unit board is used as the basic unit to splice into the size required by the user.
according to the size of pixels.
the indoor screen is divided into P2, P3, p3.75, p4.8, P5, P8, P10, etc.
the indoor screen is divided into P2, P3, p3.75, p4.8, P5, P8, P10, etcThe indoor screen area is generally less than 1 square meter to more than 10 square meters.
the point density is relatively high. When used in non direct sunlight or lighting environment, the viewing distance is more than a few meters, and the screen body does not have the ability of sealing and waterproof.
the indoor display screen is mainly based on dot matrix module.
because the brightness requirement of the display screen is not high when used indoors, the dot matrix module has a high cost performance ratio.
the indoor display screen is mainly based on dot matrix moduleOutdoor LED displayOutdoor LED displays are 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 to make outdoor screens generally uses a reflective cup with the function of focusing 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, According to the size of pixels,
outdoor screens are divided into * 11, P14, * 16, * 19, * 21, * 26, p36 and other specifications.
according to the size of pixels,
outdoor screens are divided into * 11, P14, * 16, * 19, * 21, * 26, p36 and other specificationsThe area of outdoor screen generally ranges from several square meters to tens or even hundreds of square meters.
the density of points is relatively sparse (mostly 1000-4000 points per square meter), the luminous brightness is 3000-6000cd / square meter (different orientation, different brightness requirements), and it can be used in direct sunlight conditions, and the viewing distance is more than tens of meters, so the screen has good wind, rain and lightning protection ability.
the outdoor screen has good lighting performanceSemi outdoor LED displayThe semi outdoor screen is between outdoor and indoor.
it has high luminous brightness and can be used outdoors without direct sunlight. The screen body is sealed to a certain extent, usually under the eaves or in the window3、 According to the display performance classification:Graphic displayIt supports TXT, BMP and other files.
it can display simple plane pictures.
it also has the function of offline operation.
if the display content does not change, you can directly turn on the power supply of the screen without turning on the control computer. The display mode supports expansion and display There are more than ten ways, such as instant, etc.
the content can be freely adjusted (including static) between 0-255 seconds.
it can automatically display different contents that users want to display in a cycle, which are divided into three kinds: long resident, temporary resident and real-time. After production, it is sent to the screen for display through RS232 and RS485 serial ports.
it can be used for automatic displayVideo display screen Display content real-time synchronization.
it is convenient to choose the size of the display screen at will. There are 256x256x26777216 kinds of color change combinations. The scanning field frequency is greater than 200 Hz, and the human flesh eye can hardly see the scanning line. The gamma high-speed correction design without gray loss is realized. The parameters can be selected by the user, and various gray level adjustment and brightness control functions can be easily realized, making the image color soft and realistic, It is easy to learn and use, with dozens of playback modes, can play video information, and has the function of automatic black screen when the computer is switched on and off, which improves the service life of the display screen and avoids the computer switching on and off, The interface of the display screen is disorderedLED bar screenUsually one or two lines of monochrome or bicolorThe special remote controller can be used. It has the function of offline operation, that is, the control machine can be turned off after the display content is edited and sent to the display screen.
there are three storage modes of display content: long resident, temporary resident and real-time.
different contents can be scrolled and 4000 Chinese characters can be displayed. After the production, it is generally sent to the screen through RS232 serial port, The communication line is twisted pair.
it has strong anti-interference ability. RS232 interface is used for communication distance within 100 meters, and RS485 interface is used for communication distance within 100-500 meters.
the communication line is twisted pairAs a new medium,
LED strip screen is also a new decorative material, which can be embedded in many interior decorations to make the decoration more dynamic. The constantly updated subtitles can be used as a new notice board, Promotional offers and promotional information, etc.
greatly improve the grade of interior decoration.
has a good visual effect.
