What is the classification of the LED display according to the display performance? What are the precautions for the LED display?
Guide: LED Display – LED stands for Light Emitting Diode, a type of semiconductor device that emits light when an electric current passes through it. LED displays are widely used to show various types of information such as text, graphics, images, animations, and videos. These displays consist of multiple light-emitting diodes arranged in a matrix, typically using red, green, and blue (RGB) colors to produce full-color visuals. Depending on the display purpose, there are different types of LED screens, each with specific features and applications. In this guide, we will explore how LED displays are classified based on their performance and what precautions should be taken when using them.
Classification of LED Displays by Display Performance:
Video Display: Typically refers to full-color LED screens that can display high-resolution video content, making them ideal for outdoor advertising, digital signage, and event venues.
Text Display: Usually single-color LED screens designed for displaying simple text messages, often used in public transportation, retail environments, and information boards.
Graphic Display: Generally dual-color or multi-color LED screens that can display more complex images and graphics, suitable for presentations, exhibitions, and commercial displays.
Quote Display: Often uses numeric tubes or single primary color LEDs, commonly found in digital clocks, scoreboards, and basic information displays.
Important Precautions for LED Displays:
Switching Procedures:
1. When turning on the LED display, follow the correct sequence: power on the system first, then activate the screen.
2. When turning off the screen, always switch it off before disconnecting the power supply. Failing to do so may cause sudden brightness, potentially damaging the LEDs.
3. Ensure a minimum interval of 5 minutes between switching operations to allow the system to stabilize.
4. Only turn on the LED display after the computer has entered the engineering control software to avoid improper initialization.
5. Avoid powering on the LED display in a full white screen state, as this can cause a large inrush current, risking damage to the system.
6. Do not power on the display if the system is in an out-of-control state, as this can also lead to excessive current draw.
7. If part of the screen becomes unusually bright, turn it off immediately. Prolonged operation in this condition can shorten the lifespan of the LEDs.
8. If the power switch frequently trips, check the wiring and consider replacing the switch if necessary.
9. Regularly inspect the mounting hardware. If any parts are loose, adjust or reinforce them promptly to prevent accidents.
10. Protect the control unit from pests by placing rat repellents or other deterrents, especially in areas prone to insect or rodent infestations.
Control Unit Considerations:
1. Make sure the power cable for the computer and control unit is properly connected, without reversing the live and neutral wires. Always plug it into the original socket.
2. Before powering up any control equipment, double-check all connections and ensure that the control board is securely fastened.
3. Do not alter the position or length of communication cables or flat connectors unless absolutely necessary.
4. If you notice signs of short circuits, tripping, burnt wires, or smoke after moving the equipment, stop testing immediately and investigate the issue before proceeding.
