There are significant differences between the old COB LED display and the new COB LED display in many aspects. The following is a point-by-point representation and summary of the characteristics of the two:
Features of the old COB LED display
1. Packaging technology: The old COB LED display may be more traditional in packaging technology, with LED chips packaged on PCB boards, but the specific packaging technology and details may vary from product to product.
2. Pixel density: Although COB technology itself helps to achieve high pixel density, the pixel density of old products may be relatively low due to technical and cost limitations.
3. Brightness and contrast: The brightness and contrast of old COB LED displays may vary depending on product design and usage scenarios, but in general, they may not meet the standards of new products.
4. Stability and reliability: The stability and reliability of old COB LED displays depend on their design, materials and manufacturing processes, but there may be some room for improvement compared to new products.
5. Energy saving and environmental protection: In terms of energy saving and environmental protection, old COB LED displays may have used LED lamp beads as light sources, but the specific power consumption and environmental performance may vary from product to product.
Features of the new COB LED display
1. Packaging technology: The new COB LED display uses more advanced packaging technology, such as overall packaging, which enhances the reliability of the system and reduces the failure rate of lamps.
2. Pixel density: The new COB LED display has a higher pixel density and can provide clearer and more delicate image effects. This is due to the packaging method of COB technology, which can combine multiple LED chips on a substrate to achieve higher pixel density.
3. Brightness and contrast: The LED lamp beads used in the new COB LED display have higher brightness and higher contrast, which can present clearer and more vivid images. This enables the new product to maintain excellent display effects under various lighting conditions.
4. Stability and reliability: The new COB LED display uses high-quality LED lamp beads and electronic components, which has higher stability and reliability. At the same time, COB packaging technology also reduces the operation of high-temperature and high-precision processes, further enhancing the reliability of the system.
5. Energy saving and environmental protection: The new COB LED display performs better in energy saving and environmental protection. Because LED lamp beads are used as light sources, it has lower power consumption and longer life than traditional display screens. At the same time, this design also reduces energy waste and environmental pollution.
Summary
The new COB LED display is superior to the old products in packaging technology, pixel density, brightness and contrast, stability and reliability, energy saving and environmental protection. These improvements make the new COB LED display more widely used in digital signage, commercial advertising, stage performances and other fields. However, the specific product to choose still needs to be determined according to actual needs and budget.
