P0.9 COB LED display shows significant advantages over P1.25 in many aspects. The following is a comparative analysis of the two models, as well as the main features of COB technology. I hope it can provide some help to everyone.
一、Comparison between P0.9 and P1.25
1、Smaller dot pitch:
The dot pitch of P0.9 is only 0.9375 mm, while the dot pitch of P1.25 is 1.25 mm. The reduction in dot pitch means that in the same display area, P0.9 can accommodate more pixels, thus providing higher resolution and clearer display effects.
2、More delicate visual effects:
Due to the reduction in dot pitch, the P0.9 display can show more details and layers when presenting images, making the picture more delicate and realistic.
二、What are the characteristics of COB technology?
1）Stability and reliability
Advanced packaging technology: Using advanced COB (Chip on Board) packaging technology, the LED chip is directly packaged on the substrate, without the need for brackets and reflow soldering, which improves the stability and reliability of the display.
Strong anti-collision ability: Since the device is enclosed in the PCB board and the surface is fixed with glue, the COB LED display has stronger anti-collision ability during transportation, installation and use, reducing the occurrence of adverse phenomena such as falling lights and broken lights.
2）Display effect and color reproduction
High color reproduction: The COB LED display uses a “surface” light source to emit light, effectively suppressing moiré and reducing light refraction, making the color softer and more natural, and the color reproduction is higher.
Good luminous uniformity: Thanks to advanced packaging technology and high-quality luminous materials, the COB LED display has good luminous uniformity, high color and brightness uniformity, and a more consistent overall display effect.
3）Heat dissipation efficiency and service life
High heat dissipation efficiency: COB LED display screen has lower heat dissipation rate and higher heat dissipation efficiency, which helps to maintain long-term stable operation and extend the service life of the display screen
Suitable for long-term operation: Due to its high heat dissipation efficiency and good stability, COB LED display screen is particularly suitable for occasions that require long-term stable operation, such as studios, high-end conference rooms, etc.
4）Design and installation convenience
Light and thin design: COB LED display is lighter and thinner, easy to install and transport, and more beautiful in appearance, suitable for application scenarios with high aesthetic requirements.
Easy to install and maintain: COB LED display supports a variety of installation methods, such as floor-standing, wall-mounted, hanging, etc., which can be selected according to the actual installation environment.
At the same time, due to its good stability and protection, the maintenance cost is relatively low.
三、In summary
COB LED display P0.9 has certain differences in resolution and clarity compared to P1.25. COB technology has shown significant advantages in stability and reliability, display effect and color reproduction, heat dissipation efficiency and service life, as well as design and installation convenience.
These characteristics make COB LED display have broad application prospects in the mid-to-high-end large-screen display market.
