介绍
As a new generation of display technology, COB LED display has gradually gained favor in the market with its excellent display effect and stable performance. However, compared with other types of LED display screens, the price of COB LED display screens is generally higher. Why is this?
1. What is the cost of the COB LED display screen?
When it comes to COB LED display screens, the first thing that comes to mind is their excellent display effect and stable performance, but with them comes their high price. So, where is the cost of COB LED display screens? Let’s explore it together.
1). R&D cost:
COB display screens use a fairly advanced packaging technology, which is not achieved overnight but requires continuous research, development, and improvement.
Just think about it: to stick such a small LED chip directly to the PCB board and to ensure that they work steadily, how much effort does it take?
Therefore, the R&D cost is naturally high. This does not include the application of patented technologies, the improvement of production processes, the testing and verification of products, etc., all of which cost money.
2). Production method and transformation cost:
The production process and packaging method of COB display are different from traditional SMD packaging. It is like you have to redecorate and buy furniture when you move from a small house to a big house.
If manufacturers want to produce COB displays, they have to buy new equipment, transform the production line, and train workers.
These are all real money investments! Moreover, the market share and production scale of COB displays are still small, and it is even more difficult to reduce production costs through large-scale production.
3). Complexity of packaging technology:
COB packaging technology is really a craft. You have to stick the LED chips on the PCB board accurately, and you have to put on “protective clothes” for them to ensure that they are not disturbed by the external environment when they are working. This requires precise operation and high-quality materials.
Think about it: if the craftsmanship and the materials are not good, can the display be good? Therefore, the complexity of this packaging technology is also an important reason for the high cost of COB display.
4). Other cost factors:
In addition to the above, the cost of COB display screens is also affected by factors such as raw material costs, market demand, and brand premium. For example, once the prices of raw materials such as LED chips, packaging materials, and PCB boards rise, the price of the display screen will also rise.
In addition, the market demand for COB display screens is so strong that supply exceeds demand, so the price is naturally high. For example, some well-known brands have products with guaranteed quality and good service, so the price is correspondingly higher.
5). Cost trend:
However, don’t worry too much. With the continuous advancement of technology and the continuous optimization of production processes, the production cost of COB display screens is expected to gradually decrease.
Just like when you learn a craft, you may not be proficient at the beginning, but over time, your craftsmanship will get better and better, and your efficiency will also increase. Similarly, with the expansion of the industry scale and the intensification of market competition, the price of COB display screens is expected to be more affordable.
So, there is a reason why the cost of COB LED display screens is high. But don’t be scared by the price; after all, good things are worth looking forward to.
2. Product performance and advantages of COB LED display screen

3. What is the market demand and supply of COB LED display screens?
Speaking of COB LED display screens, the current market situation is really hot! Let’s talk about its market demand and supply.
1). Limited market supply
Did you know that there are not many manufacturers in the market that can master the production process of COB display screens? This is not something that any manufacturer can do. It requires certain technical strength and production experience.
Therefore, this leads to a relatively limited supply. Think about it: if there are fewer things, the price will naturally go up. Therefore, the price of COB display screens is not cheap now!
2). Strong market demand
Let’s talk about the demand; it is extremely high! COB display screens are very popular on high-end occasions because of their excellent performance.
For example, some high-end commercial displays, conference centers, performing arts venues, etc., have chosen to use COB display screens. As a result, the demand is naturally large. However, the supply is limited, which further pushes up the price.
The current situation is that there are many people who want to buy COB display screens, but there are not many manufacturers who can sell them.
This situation of supply and demand has caused the price of COB display screens to soar! However, this also shows the strength and charm of COB display screens. After all, good things are always in high demand!
In general, the market demand for LED display screens with COB technology is very strong now, but the supply is a bit behind. This situation is expected to continue for some time. If you want to buy the COB display screen you like, you may have to spend some time and money.
However, I believe that with the continuous advancement of technology and the continuous development of the market, the supply of COB displays will gradually increase in the future, and the price will be more reasonable. Let’s wait and see!
4. Other cost factors of COB LED display screens
When it comes to COB LED display screens, the first thing that comes to mind is its cool display effect and high-end positioning. But do you know? There are actually many cost factors behind this that affect its final price. Today, let’s talk about two of the big ones: raw material costs and brand and service.
1). Raw material costs, that’s real
COB display screens, to put it bluntly, are made of a bunch of high-tech raw materials. LED chips, packaging materials, PCB boards, and other things that sound very high-end are all essential for making COB display screens.
- LED芯片：
This is the “heart” of the display screen, and the quality is directly related to the brightness and life of the display screen.
Once the chip price rises, the cost of the display screen will also go up. Just like when you buy a mobile phone, once the processor is upgraded, the price will definitely increase a bit; the reason is the same.
- Packaging material:
This is like the “clothes” that the chip wears, which must be both beautiful and practical. The packaging material must be good to ensure that the display can work steadily in various environments. Once this material is expensive, the cost of the display will also be high.
- PCB板：
This is like the “skeleton” of the display, which must be strong. The quality of the PCB board directly affects the stability and reliability of the display. If the price of the PCB board rises, the cost of the display must also rise.
Therefore, the change in the price of raw materials directly affects the cost of the COB display. Once the price of raw materials rises, the price of the display will also rise.
2). Brand and service are also valuable
When buying a COB display, in addition to product quality, you must also look at the brand and service. A display from a well-known brand is definitely more secure.
Brand added value: Just like when you buy a brand-name bag, in addition to the quality of the bag itself, you have to pay the brand fee. The same is true for COB displays. The added value of well-known brands is not low. If you buy a display from a well-known brand, you will have a lot of faces when you go out and tell others!
- 售后服务：
This is very important. If you buy a display screen, if there is a problem, someone has to solve it for you, right?
The after-sales service of well-known brands must be more in place. They have to ensure that your display screen can always work steadily. Otherwise, it will be bad if they smash their own brand.
- Product quality assurance:
Well-known brands have very high requirements for product quality. They have to ensure that every display screen has been strictly tested and the quality is absolutely guaranteed. The cost behind this is definitely not low.
Therefore, brand and service are also important factors affecting the price of COB display screens. If you buy a display screen from a well-known brand, the service and guarantee you enjoy will definitely be different, and the price will naturally be higher.
In general, the cost of COB LED display screens is not that simple. Raw material cost, brand, and service are all important factors affecting its price. So, the next time you see the price of COB display screens, you will know the doorway behind it.
结论
In summary, there are many reasons for the high price of COB LED display screens, including its unique technical characteristics and production costs, and it is also closely related to its excellent product performance and strong market demand.
In addition, factors such as raw material costs, brands, and services also have an important impact on prices.
