With the advancement of technology, LED signs have become the first choice for various information displays and advertising communications due to their high efficiency, durability and versatility. This article will introduce the components, main types and working principles of LED signs in detail to help customers gain a deeper understanding of the basic architecture and application scenarios of this advanced technology.
- Composition of LED Signs
LED signs are mainly composed of the following 6 key components:
a. LED lamp beads: This is the core of LED signs. It is made of semiconductor materials and can directly convert electrical energy into light energy. LED lamp beads have the characteristics of long life, low energy consumption and fast response speed. Let's learn about the working principle of LED lamp beads.
b. Control card: The control card is the brain of the LED sign, responsible for receiving input signals and controlling the on and off and color changes of the LED lamp beads to achieve dynamic display effects.
c. Power module: Provides a stable power supply for the LED sign to ensure its normal operation.
d. Box and frame: used to fix LED lamp beads and protect internal components, usually made of materials such as aluminum or stainless steel, with good heat dissipation performance and stability.
e. Connecting wire: connects various components to ensure the transmission of signals and power.
f. Software system: used to design and edit display content, as well as remotely control LED signs.
- Types of LED signs
According to application scenarios and technical characteristics, LED signs are mainly divided into the following categories:
Classification by display color:
Monochrome LED signs: can only display one color, suitable for simple text or symbol display, such as monochrome red, monochrome green.
Two-color LED signs: composed of two-color LED lamp beads, can display a combination of multiple colors, such as red and green.
Full-color LED signs: using red, green and blue LED lamp beads, through the combination of different brightness, can display full-color images and videos. Here is the knowledge about nit brightness.
Classification by application scenario:
Indoor LED signs: used in indoor environments, with moderate brightness, usually used in shopping malls, exhibition halls and other places. Outdoor LED signs: used in outdoor environments, with high brightness, waterproof, dustproof, UV-proof and other characteristics, suitable for billboards, traffic signs, etc. What is the difference between indoor LED displays and outdoor LED displays?
Classification by display method:
Fixed LED signs: installed in a fixed position, used to display specific content for a long time, such as advertising screens on the exterior walls of buildings. Mobile LED signs: installed on vehicles or movable devices, and the display location can be changed at any time, such as mobile advertising vehicles. How much does an LED advertising vehicle cost?
- Working principle of LED signs
The working principle of LED signs mainly includes the following aspects:
Signal reception and processing:
Input signal: Display content such as pictures, text, videos, etc. is input through a computer, video player or other signal source.
Signal processing: The control card receives the input signal, and after data processing and format conversion, it converts it into a digital signal suitable for LED module display.
Image rendering and display:
Pixel control: Each LED lamp bead represents a pixel, and the control card adjusts the brightness and color of each pixel by controlling the current size.
Image splicing: Multiple LED modules are connected through circuits, work together, and splice into a complete display screen to display large-area images and videos. Take you to understand LED display soft modules in 5 minutes.
Synchronization and refresh:
Synchronization control: The control card and the LED module are synchronized to ensure the continuity and consistency of the displayed content.
Refresh frequency: By quickly refreshing the displayed content, the image flickers and the smoothness and stability of the display effect are avoided.
Power management and heat dissipation:
Stable power supply: The power module provides a continuous and stable current to ensure the normal operation of the LED lamp beads.
Heat dissipation: The heat dissipation system effectively dissipates heat, prevents components from overheating, and ensures long-term stable operation of the equipment.
