COB (Chip on Board) is a kind of LED display packaging technology.
LED light-emitting chips are directly bonded to the module board with high precision and connected to driver components on the module board through special media for overall protection of the light-emitting surface. COB packaging eliminates the two key procedures of turning LED chips into lamp beads and reflow soldering as compared to standard SMD packaging.
Advantages of COB display
1. Ultra-fine pitch and high definition: COB display can achieve point pitch below 1.0mm, such as P0.6, P0.7, P0.93, P1.25, P1.56, P1.87 and other models. This The display screen is more delicate and the resolution is greatly improved, resulting in fuller and clearer visual effects.
2. Surface light source: COB display screen uses "surface light source" to emit light, which makes the light feel more uniform and soft. It will not feel dazzling even when viewed at close range. It is suitable for occasions that require long-term gaze or close viewing.
3. Excellent protective performance: COB technology directly encapsulates the light-emitting chip on the PCB board and uses epoxy resin glue to solidify it. It has a very high level of protection and can effectively resist natural phenomena such as external impact, vibration, water vapor, oxidative corrosion and static electricity. and damage caused by human factors. This design makes the COB display less susceptible to damage during transportation, installation, and maintenance, and its durability is significantly improved.
4. Color performance and image quality optimization: COB technology improves the uniformity and consistency of colors by reducing the dot spacing, making the displayed colors softer and more delicate, and the color saturation and contrast are enhanced, thereby providing a better visual experience. .
5. Easy maintenance and long service life: Improvements in packaging methods reduce exposed parts, reduce the failure rate caused by dust, moisture, impact and other factors, and extend the overall service life of the display. At the same time, maintenance costs are also reduced accordingly, because lamps are less likely to fall out or break down, reducing the frequency of maintenance.
