LED displays can be classified in the following ways:

I. By Primary Color

Single red, single green, red-green dual-primary color, red-green-blue tri-primary color, full-color, natural color; single-primary-color LED displays (including pseudo-color LED displays), dual-primary-color LED displays, and full-color (tri-primary-color) LED displays. They can also be classified by grayscale level, such as 16, 32, 64, 128, and 256-level grayscale LED displays.

II. By Display Device

* LED Digital Display: The display device is a 7-segment LED tube, suitable for making clock screens, interest rate screens, etc., displaying numbers.

* LED Dot Matrix Graphic Display: The display device is a dot matrix display module composed of many evenly arranged light-emitting diodes. It can synchronously display Chinese characters, English text, and graphics with a computer, suitable for playing text and image information.

* LED Video Display: Video displays are controlled by a microcomputer, displaying rich graphics and text in a real-time, synchronous, and clear manner. They can also display 2D or 3D animation, videos, television programs, VCD programs, and live broadcasts. III. Classification by Application

III. Indoor Display Screens

Smaller light-emitting points, generally φ3-8mm, display area typically several to tens of square meters.

Outdoor Display Screens: Area typically tens to hundreds of square meters, high brightness, can operate in sunlight, and are windproof, rainproof, and waterproof.

IV. Classification by Light-Emitting Point Diameter

Indoor Screens: φ3, φ3.75, φ5mm, etc.

Outdoor Screens: φ10, φ12, φ16, φ19, φ20, φ21, φ22, φ26mm, etc.

V. Classification by Display Method

Classified by display method: Static, horizontal scrolling, vertical scrolling, and page-turning displays, etc.

VI. Classification by Function

Text and graphic display screens, multimedia video display screens, market data display screens, bar displays, interest rate displays, text LED electronic displays, graphic LED electronic displays, computer video LED electronic displays, television video LED electronic displays, and market data LED electronic displays, etc. Market data LED electronic displays generally include LED displays for securities, interest rates, futures, etc. VII. Classification by Working Method Display screens can be classified into synchronous displays and asynchronous displays based on their working method.
