3D outdoor LED display

Why Choose Common cathode outdoor energy-saving LED display?

Outdoor LED display plays a vital role in many fields such as commercial advertising, traffic instructions, and public information release. However, behind the booming outdoor LED display market, how to choose the development technology path to make outdoor LED screens more energy-efficient? Among them, common cathode outdoor energy-saving LED display is a good development direction. However, this technology is also facing many challenges and opportunities. But SightLED is using innovative technology to break through development.

Current status of outdoor LED display technology

I) Disparity in market share

At present, there are two major technical paths in the outdoor LED display market: common anode technology and common cathode technology.

According to relevant statistics, common anode technology has a market share of up to 80%, while common cathode technology accounts for less than 20%. Such a disparity in market share reflects the huge gap between the two technologies in market competition.

II) Difference maturity chain

From the perspective of the industrial chain, after years of precipitation and accumulation, common anode technology has built a highly complete industrial ecosystem.

On the raw material supply side, many LED display suppliers have formed a stable supply system around the common cathode technology. All kinds of high-quality raw materials such as LED chips and circuit boards are not only in sufficient supply, but also reasonably priced. This also provides a solid guarantee for the large-scale production of common cathode  LED display screens.

In the product manufacturing link, a large number of LED display companies have accumulated rich experience and formed standardized production processes. They can efficiently and stably produce various common cathode display products, ensuring the quality and supply speed of the products.

In terms of after-sales support, the perfect service network is spread all over the country, and the professional maintenance team can respond to customer needs quickly, solve equipment failures in time, and reduce the impact of equipment failures on customer business.

In contrast, the industrial chain of common cathode outdoor LED display technology is still in the development stage.

Some Key accessories such as LED lamp beads, power supplies, and driver ICs. They not only have limited supply channels, but also have difficulty in supply chain organization. Due to the small number of companies producing parts related to common cathode technology: 

  • the production process of these parts is not mature enough, resulting in a long supply cycle;
  •  it often takes 3-6 months to complete order delivery.

In addition, there are major problems with the adaptability of parts produced by different manufacturers. LED display manufacturers need to spend a lot of time and energy on debugging during the assembly process, which not only increases production costs, but also seriously affects the market promotion speed of outdoor common cathode technology LED display.

(III) Different product design complexity

At the product design level, there are significant differences between common cathode and common anode technologies. The PCB boards of the two are not interchangeable. The design of common cathode PCB is complex and requires the use of more types of components, including special resistors, capacitors, and circuit connectors. This not only increases the difficulty of design, prolongs the LED  display development cycle, but also leads to an increase in production costs.

(IV) Obvious cost differences

The difference in cost level is the key factor in the dominance of common cathode technology. After years of development, the cost of common cathode technology has been effectively controlled under the promotion of large-scale production, and it has strong cost competitiveness.

In contrast, due to the immature industrial chain and complex design, the cost of common cathode technology remains high, 15% – 35% higher than that of common cathode technology. Therefore, common cathode LED display screens lack competitive advantages. In some cost-sensitive project biddings, common cathode LED display are often eliminated because of their high prices.

Development of Common Cathode Outdoor Energy-Saving LED Display Screen

I) Technical Bottleneck Restriction

Although common cathode energy-saving outdoor LED display screen has potential advantages in energy saving, it still faces many technical bottlenecks.

For example, in terms of luminous efficiency and color uniformity, there is still a certain gap compared with common anode technology. In addition, the stability of common cathode technology needs to be improved. After long-term use, it is easy to have problems such as brightness attenuation and color deviation, which seriously affects the service life of the product and user experience.

II) Difficulty in Market Promotion

Due to the immature industry chain, high cost and product stability of common cathode technology, it faces many difficulties in the process of market promotion.

When choosing outdoor LED display screens, customers often give priority to factors such as LED display cost, stability and after-sales service. However, common cathode LED display are relatively weak in these aspects, which makes customers less accepting of them, thus limiting the expansion of the market share of common cathode outdoor energy-saving LED display screens.

(III) Imperfect Industry Standards

At present, the common cathode outdoor energy-saving LED display screen industry lacks unified standards and specifications.

Products from different manufacturer differ in technical parameters, quality requirements and testing methods, which brings great difficulties to product quality assurance. At the same time, it also affects the healthy development of the industry, causing some low-quality products to flood the market and harm the interests of consumers.
