The LED Screen, as a new medium, sports luminous text, is more attractive to attract attention, large amount of information, updated at any time, has very good advertising and notice effects. LED screens are simpler than neon lights, easy to install and use, more effects change, and can update content at any time. It is a good indoor and outdoor visual media. LED screens are high-tech electronic products, which are relatively expensive and have been used in government and units. Technology continues to advance, prices continue to decrease, and assembly and maintenance are simpler. The small LED strip screen, because of its low price, simple installation and use, is widely accepted by the public, gradually enters large and small stores, and the application is more popular, and gradually becomes popular. The application is also very extensive: new media, new effects, new business LED strip screen as a new media, is also a new type of decorative material, can be embedded in a lot of interior decoration, making the decoration more dynamic, constantly updated subtitles, can be used as a new notice Board, promotional offers and promotional information. Greatly improved the grade of interior decoration, with a good visual effect. Due to the technical content of the installation and use of the LED strip screen, the development in the advertising industry is restricted. Mastering LED technology can improve the technical content of interior decoration and expand business.
The LED strip screen is embedded in a variety of devices for the general public due to its simple control. The font is large, dynamic, and has a large amount of information. It is suitable for long-distance viewing and timely broadcasts the latest news to the public to attract public attention. Widely used in queuing systems, reporting systems, water dispensers, etc. LED strip screen control card, simple and stable, can be easily embedded into the system, saving developers the cumbersome work of developing LED display, focusing more on the system's functions and innovation. The LED strip screen control card development kit provides detailed development examples, providing a good environment for your system integration and 2 developments.
To make an LED display, you must first understand the components: cell board, power supply, control card, wiring, switching power supply and LED strip screen control card.
The unit board is one of the display core components of the LED, and the quality of the unit board directly affects the display effect. The unit board is composed of an LED module, a driving chip and a PCB circuit board. The LED module is actually packaged in a matrix by a large number of LED light-emitting points with resin or plastic. The driver chip is mainly 74HC595 74HC245/244 74HC138 4953. The common unit board specifications for indoor strip screen are: Parameter: D=3.75; Point distance 4.75mm 64 points wide x 16 points high, 1/16 sweep indoor brightness. Single red / red and green two-color parameter interpretation: Light diameter: refers to the diameter of the light-emitting point D = 3.75mm light-emitting point distance 4.75mm ---- according to the distance of the viewer, the general choice of indoor 4.75 unit board size: 64x16- -- The most commonly used cell board, the easiest to buy, and the cheapest. 1/16 sweep: The control mode of the unit board. Indoor brightness: refers to the brightness of the LED light-emitting point, and the indoor brightness is suitable for the environment that needs to be illuminated by fluorescent lamps during the day. Color: single red, most commonly used, and the cheapest price. Two colors generally refer to red and green, and the price is high. If you want to make a 128x16 dot screen, you only need to connect 2 cell boards together.
power supply
The power supply generally uses a switching power supply, 220V input, and 5V DC output. It should be pointed out that since the LED display screen is a precision electronic device, a switching power supply is required, and a transformer cannot be used. For a single red indoor 64x16 cell board, the current is 2A when fully lit. It is inferred that when the 128x16 two-color screen is fully lit, the current is 8A. The 5V10A switching power supply should be selected.
The COB light series is a main light that improves the brightness of the stage lighting. The COB light with the focus function can be switched between the function of concentrating bright light and emitting soft light in a large area, so that it can meet the requirements of different brightness and spotlight on the stage. need. The difference between COB and other series is that white light and warm white light are mainly used in color, which is the main source of light on the stage, stand an important position on stage.
