Now LED displays can be seen everywhere on the street, as well as decorative LED lights and LED car lights, LED lights can be seen everywhere, and LED has been integrated into every corner of life.
In a city, whether it is a prosperous metropolis or a small and medium-sized town, you will often see LED full-color large screens, especially in the commercial center of a city, whether in or outside shopping malls, LED full-color large screens It has become commonplace, and has even become a symbol of a city center. Because of this, more and more people want to know more about LED full-color large screen, because it is very important for many people to choose what kind of media to promote their brand or service.
With the wide application of full-color LED displays in various fields and the growing market size, LED full-color product technology will also be further improved. In the future, the full-color LED display will show the development trend of large screen, high-definition and high density, energy-saving and intelligent, light and thin, civilian, and outdoor indoor screen, etc., to achieve clearer and more creative new applications.
As a high-tech product, LED display has attracted people's attention. The intelligent full-color display adopts computer control and integrates light and electricity, and has been widely used in various fields. The pixels use LED light-emitting diodes, and many light-emitting diodes are arranged in a dot matrix to form an LED array, which then forms an LED screen. Through different LED driving methods, images with different effects can be obtained. Therefore, the advantages and disadvantages of LED driver chips play an important role in the display quality of LED displays. LED driver chips can be divided into general-purpose chips and special-purpose chips.
The LED full-color large screen consists of many individual LED displays. Since the LED display can be seamlessly spliced, the entire LED full-color large screen looks like a complete large screen, while a single LED display is composed of cabinets, display modules, power supplies, electronic components in the modules, etc. Cabinet materials mainly include iron materials, nano-polymer materials, carbon fiber materials, magnesium alloy materials, die-cast aluminum materials, etc. Among them, iron and die-casting aluminum cabinets are the most commonly used LED display cabinets.
In the future, in order to obtain a better viewing effect, people will have higher and higher requirements for the fidelity of the screen definition. If you want to be able to restore the authenticity of colors and display clear images on smaller monitors, then high-density and fine-pitch LED displays will be one of the future trends.
Display modules can be mainly divided into plastic modules and die-cast aluminum modules. The advantage of plastic modules is mainly the low price, which is more in line with the mass market. The advantages of die-casting aluminum modules are mainly flame retardant, which is not flammable under outdoor high temperature conditions. Large deformation, high flatness, long life, fast heat dissipation, convenient front and rear maintenance, etc., but its higher price, more in line with higher requirements for products and installation conditions.
Since the LED is a current characteristic device, that is to say, under the premise of saturated conduction, its brightness changes with the change of current, and changes with the change of the voltage at both ends. The biggest feature of the dedicated chip is to provide a constant current source output to ensure the stable driving of the LED and eliminate the flickering phenomenon of the LED. With the characteristics of large output current and constant current, it is suitable for occasions requiring large current and high image quality, such as outdoor full-color screens, indoor full-color screens, etc.
Under the current economic conditions, LED full-color large screen has a wide range of applications. According to its application field, it can be divided into outdoor LED full-color large screen and indoor LED full-color large screen. Outdoor LED full-color large screens usually choose screens with larger spacing, such as P10, P8, P6 and P5, etc. This is mainly because large LED screens for outdoor use are usually larger in size, and LED displays with larger pitches are more expensive than LED displays with small pitches. It's much lower, and because outdoor LED displays are usually viewed from farther away.
In the past, LED displays were mainly used in high-end places such as banks and stock exchanges, and most of them were single-color and two-color LED displays. The launch of the full-color LED screen broke the scope of the display and quickly expanded to the main field. As display technology has advanced, service levels have increased and prices have plummeted, the use of full-color screens has grown from the previous high-end occasions to private portals. Therefore, the civilianization of LED full-color screens will also become one of the future development trends of the industry.
