Question

What are the categories of LED full-color screens?

Answer 1

The classification of LED full-color screens can be carried out from multiple angles. 

The following are several main classification methods and their detailed descriptions:

Classification by application

1. Indoor full-color LED display screen: mainly used in indoor environments, such as commercial advertisements, multi-functional conference halls, stage backgrounds, digital 3D teaching, and multimedia teaching. This type of display screen has a small luminous point and dense pixel spacing, which is suitable for close viewing. Common models include P2, P2.5, P3, P4, P5, P6, etc., where the P value represents the pixel spacing in millimeters.
2. Outdoor full-color LED display screen: mainly used in outdoor environments, such as outdoor commercial advertisements, stage backgrounds, etc. This type of display screen has a large luminous point, a large pixel spacing, high brightness, can work in the sun, and has windproof, rainproof, and waterproof functions, which is suitable for long-distance viewing. Common models include P3, P4, P5, P6, P8, P10, P16, etc.

Classification by primary colors

• Full-color LED display: Each pixel is composed of three primary colors: red, green, and blue. By controlling the grayscale level of each primary color, more than 16 million colors can be combined to achieve a full-color display effect.

Classification by function

1. Synchronous display: This type of display needs to work synchronously with a computer or other video source to display the screen of the computer or other video source in real time. It is mainly used on large full-color display screens and rental screens.
2. Asynchronous display: This type of display has a storage function, which can store the content to be played in the control card, and does not need to be connected to a computer or other video source for a long time. It is mainly used on small and medium-sized display screens and advertising screens.

Classification by special types

1. LED small-pitch display: such as P1.25, P1.56, P1.667 and other models, mainly used in public security systems, command center monitoring halls and other places that require high-definition display. This type of display has a smaller pixel pitch and a more delicate display effect.
2. LED flexible screen: Made of flexible materials, it can be bent and folded, and is suitable for installation surfaces of various irregular shapes. Commonly used in creative display, stage performance and other scenes.
3. LED rental screen: designed for the rental market, easy to disassemble, transport and store. Commonly used in weddings, celebrations, performances and other events.
4. LED transparent screen: with high transparency, it can be used in combination with transparent materials such as glass, without affecting indoor lighting and sight. Commonly used in commercial windows, stage backgrounds and other scenes.
5. LED floor tile screen: specially designed for ground installation, with strong load-bearing capacity, waterproof and non-slip. Commonly used in stage performances, bar entertainment and other places.
6. LED special-shaped screen: customized display screens of various special shapes according to customer needs, such as arc, circle, sphere, etc. Commonly used in KTV/bar DJ station, hotel/catering/commercial hall and other places.

Classification by control mode

• Digital display: the display pixel is a 7-segment digital tube, suitable for making clock screens, interest rate screens, etc.
• Graphic display screen: the display pixel is a dot matrix module, suitable for playing text and image information.
• Video display: Display pixels are composed of many light-emitting diodes, which can display various video files such as videos and animations.

In summary, there are many ways to classify LED full-color screens, and you can choose the appropriate type according to the specific application scenarios and needs.

Answer 2

1. Indoor full-color box type according to indoor installation method

2. Synchronous control system (control card): Nova

The control card is the core component of the LED display screen, which controls the input and output of the signal. The full-color screen mainly uses the synchronous control card. 

The synchronization card is synchronized with the LED through the PC (entering the copy mode), such as Nova, using the LED studio software to achieve PC and screen synchronization, which can realize the playback of files and videos.
