What are the types of LED displays?

thank you for your information.
thank youThe difference of LED display screen is classified according to the primary colorMonochrome LED displayMonochrome LED display has only one backlight color.
most of them 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 higher 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 displayTwo color LED display is a LED display made by putting red and green LEDs together as one pixel.
each pixel has two basic colors of red and green.
yellow can be superimposed. Under the condition of gray control, e69da5e887aa62616964757a6869616f331333339656439 can be combined to produce up to 65535 colors by changing the gray levels of red and greenFull 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 blueThe difference of LED display screen is classified according to the use environmentIndoor LED displayThe indoor LED display screen is mainly used for indoorIn 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 certain size display unit board. According to the user's requirements, 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 dots is sparse (mostly 1000-4000 dots per square meter), and the brightness is 3000-6000cd / square meter (different orientations,It can be used in direct sunlight, and the viewing distance is tens of meters away. The screen has good wind, rain and lightning protection abilitySemi 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 windowThe differences between LED displays are classified according to display performanceAccording to the display performance, LED display screen can be divided into: monochrome graphic screen, dual color graphic screen, dual primary color video screen, synchronous display screen, three primary color video screen (full color screen), monochrome bar screen, dual color bar screen, quotation display screen, various display boards, etc.
quotation LED display screen generally includes LED display screen for securities, interest rate, futures and other purposes.
according to the display performance, LED display screen can be divided into three categoriesGraphic 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 The display content is synchronized in real time.
the size of the display screen can be easily selected. 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 screenIt is usually one line or two lines of monochrome or two colors.
a special remote controller can be used. It has the function of offline operation, that is, the controller can be turned off after the display content is edited and sent to the display screen.
there are three storage modes of display content, namely long-term 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.
