There are various types of LED display screens. According to different classification standards, they can be summarized into the following types:
1. Classification by color:
Full-color LED display screen: can display various colors, mostly used in indoor and outdoor advertising occasions. From outdoor P20 to indoor P0.9, there are many specifications.
Monochrome LED display screen: generally single red, mostly used to display text and other slogans, such as outdoor store signs, information display screens, etc.
Two-color LED screen: generally red and green, also used for strip screen display, mostly used indoors.
2. Classification by shape:
Arc LED display screen: usually composed of flexible soft modules, can also be realized by rotating splicing with conventional LED modules, mostly used in advertising occasions, can be made into various arc effects such as inner arc, outer arc, circle, etc.
3. Classification by transparency:
LED transparent screen: including transparent grille screen and crystal film screen technology, can achieve translucent display effect, mostly used in places where transparency needs to be maintained, such as glass curtain walls.
4. Classification by application:
Indoor screen: Mainly used indoors. The manufacturing process first makes the light-emitting crystal into a dot matrix module (or digital tube), and then splices the modules into a display unit board of a certain size.
Outdoor screen: Mainly used outdoors. The manufacturing process first encapsulates the light-emitting crystal into a single light-emitting diode (single lamp), and then encapsulates multiple LED single lamps into a single pixel tube or pixel module.
5. Classification by function:
Asynchronous screen: Mainly used to display text and graphics, dynamic GIF animation. It inputs information by communicating with the computer, and its advantage is that it can be displayed offline.
Synchronous screen: The screen pixels and the control computer monitor pixels are one-to-one mapping relationships, with grayscale control, rich expression, and can play video signals.
6. Classification by process:
Direct-insert lamp unit board: Generally used outdoors, characterized by high brightness and good light-gathering effect of lamp beads.
Module unit board: The specific description of this category is not clearly mentioned in the reference article provided.
The above are the main types of LED display screens, each of which has its specific application scenarios and advantages.
When choosing an LED display, you need to choose the appropriate type based on specific needs and scenarios.
