There are significant comparison points between COB LED displays and Regular LED displays (traditional LED displays) in many aspects. Here are some of the main differences between them:
1. Packaging method:
- COB LED display: Using Chip On Board (chip on board) technology, the LED chip is directly packaged on the display module, achieving pixel-level packaging. This packaging method greatly improves the protective performance of the display screen, making the display screen more stable and reliable during transportation, installation, and use.
- Regular LED display: The traditional packaging method is used to encapsulate the LED chip in a separate lamp bead, and then fix it on the display module through welding or snapping between the lamp beads. This method is prone to errors during the packaging process, affecting the display effect and stability.
2. Display effect:
- COB LED display: Due to the use of pixel-level packaging, the spacing between LED chips is smaller and more pixels can be accommodated per unit area, so the display effect is more delicate and clear. At the same time, COB packaging technology can effectively suppress moiré patterns, making the picture smoother.
- Regular LED display: Due to the large spacing between lamp beads, the display effect is relatively rough. In addition, due to the luminous characteristics of the lamp beads, interference phenomena such as moiré patterns are likely to occur, affecting the picture quality.
3. Stability and reliability:
- COB LED display: Due to the advantages of packaging, COB LED display has higher stability and reliability during transportation, installation and use. At the same time, due to the use of epoxy resin glue curing technology, the display has stronger protective performance and can effectively resist interference from the external environment.
- Regular LED display: Due to limitations in packaging methods and lamp bead characteristics, Regular LED displays are relatively low in stability and reliability. In addition, because the connections between lamp beads are relatively fragile, they are prone to damage or falling off during transportation, installation, and use.
4. Maintenance costs:
- COB LED display: Due to the modular design, the maintenance of the display is more convenient. If a module fails, only that module needs to be replaced, not the entire display. At the same time, due to the advantages of COB packaging technology, the failure rate of the display screen is lower and maintenance costs are reduced.
- Regular LED display: Because the connection between the lamp beads is relatively fragile, it is prone to failure. If a certain lamp bead fails, it needs to be checked and replaced one by one, and the maintenance cost is high. At the same time, due to limitations in display effects and stability, the life of Regular LED displays is relatively short, increasing replacement costs.
5. Application areas:
- COB LED display: Due to its high definition, high stability, and high reliability, COB LED display is widely used in high-end display fields, such as commercial advertising, stage backgrounds, outdoor media, etc.
- Regular LED display: Due to its low cost and easy installation, Regular LED display still has a certain market share in some mid-to-low-end display fields, such as interior decoration, small advertising, etc.
In summary, COB LED displays have significant advantages over Regular LED displays in terms of display effect, stability, and reliability. However, due to its high cost, it has not been able to completely replace Regular LED displays in the market. With the continuous advancement of technology and reduction of costs, COB LED displays are expected to occupy a larger market share in the future.
