Product
COB ultra-fine pitch LED display (Chip on Board, referred to as COB) is an advanced display technology that directly encapsulates LED chips on PCB circuit boards and covers them with special resins, realizing the conversion from "point" light source to "surface" light source. This technology originated in the 1960s and has been widely used and developed in recent years.
Technical features
The main technical features of COB ultra-fine pitch LED display include:
Ultra-fine pitch: The dot pitch can reach very small values such as P0.3, P0.4, P0.5, achieving an almost seamless visual experience.
High resolution: Due to its tiny dot pitch, COB display can provide extremely high resolution and clear image quality.
Strong color reproduction ability: It can cover a wider color gamut range and accurately reproduce the thousands of colors in nature.
High contrast: The design makes the picture detail rich, black and white distinct, and the color transition natural.
High viewing comfort: Through low blue light, no flicker and other eye protection technologies, reduce the damage to the eyes caused by long-term viewing.
Application scenarios
COB ultra-fine pitch LED display is widely used in the following scenarios:
High-end conference room: Provide clear and accurate pictures to meet professional needs with extremely high requirements for details.
Command center: Ensure clear and accurate pictures can be presented even in complex environments.
Film and television post-production room: Used for high-quality video and image processing.
Home theater, commercial advertising screen, art exhibition, live sports events: Provide unprecedented visual experience and promote the transformation and upgrading of the display industry.
Technical advantages
COB ultra-fine pitch LED display is popular because of its following technical advantages:
High stability: Since the LED chip is directly packaged on the PCB board, the connection points are reduced, thereby improving the overall stability and reliability.
Good heat dissipation performance: The packaging method of COB technology helps to improve heat dissipation efficiency and extend the service life of the display.
Low maintenance cost: Due to its compact structure and low failure rate, the maintenance cost is relatively low.
Installation flexibility: COB display can achieve a thinner design and is easy to install in various spaces, including curved and irregular surfaces.
Future Outlook
With the continuous advancement of technology, the future development prospects of COB ultra-fine pitch LED display are broad:
Intelligent upgrade: In the future, COB display will integrate more intelligent functions, such as touch interaction, remote control, etc., to enhance user experience.
Green and environmental protection: With the increase of environmental awareness, COB display will adopt more environmentally friendly materials and processes to reduce the impact on the environment.
Cost reduction: With the expansion of production scale and the maturity of technology, the production cost of COB display is expected to be further reduced, making it more popular.
Application field expansion: The continuous optimization of COB technology will promote its application in more emerging fields, such as virtual reality, augmented reality, etc.
