        Under such a fever, it seems inevitable that common cathode energy saving will enter the industry, but in fact there are still many obstacles, which make LED display companies have to face up to it. If common cathode energy saving wants to really enter the industry, it has to start by solving these difficulties.

        The unavoidable patent shadow has not disappeared

        No matter from the perspective of energy saving and emission reduction, or from the perspective of driving new demand in the LED display industry, common cathode is a favorable technology. Although LED display displays are becoming more and more refined, the high power consumption accompanying the development of the industry has always been a pain point for the industry. The opening of this technology has played an important role in promoting the development of the LED display industry in the direction of energy saving. However, the patent for this technology is in foreign countries. There is only one company in my country that has been authorized, and it has not been opened to the outside world for a long time, and it has not been opened to the outside world until nearly a year. Although the technology has been opened, it is limited to China. Once the product is sold overseas, it is very likely that copyright and patent litigation will occur. Most of the LED display companies in my country are export-oriented companies, and their products are sold all over the world. If companies want to deploy common cathode energy saving, the overseas market of common cathode energy saving needs to be temporarily abandoned. On the domestic side, many enterprises have deployed common cathode energy saving in order to seek new development opportunities. The market competition is relatively fierce, so enterprises should seize the market with products that focus on both speed and quality.

        Although domestic and foreign companies attach great importance to patents, LED screen companies must also know how to protect their own rights and interests. Actively search for published materials and related technologies of common cathode technology, find favorable conditions for using common cathode technology, and improve the use of common cathode technology. Of course, there is more than one way to save energy. It requires the hard work and research and development of LED screen companies. We look forward to the next energy-saving technology, which will be in the hands of the Chinese people.

        Common-cathode energy-saving facilities are not perfect, and the main battlefield of common-cathode energy-saving lies in small spacing

        The common cathode energy-saving technology reduces the voltage from about 4V to about 3V through dual power supply control, which effectively reduces the red light power by about 30% and reduces the overall power consumption by about 10-15%. In terms of common anode technology, since the birth of LED displays, the power supply has used common anode technology. Due to the high power consumption and the demand for energy saving by end users and the country, LED screen companies have also been expanding the energy saving of common anode technology. Effect. After years of development and improvement, the energy-saving effect of the common anode technology can also achieve quite good results, and the current market is mainly based on feeding technology. Although the common cathode energy-saving technology is good, due to the "age" is still young, the corresponding industrial chain digestion and supporting facilities have not been perfected, and mass production is not yet possible, so the cost competitiveness is low. Faced with such a situation, it is necessary to develop the layout of the whole industry and promote it together in order to accelerate the rapid maturity of common cathode energy-saving products. In addition, judging from the common cathode energy-saving products released by various companies, common cathode energy-saving products with COB packaging technology are mostly used in the field of display screens with small dot pitch. From a technical point of view, key technologies such as low-current accuracy and consistency, low-ash and high-brush processing of common cathode energy saving are more suitable for small-pitch LED displays. Therefore, combined with the future development trend of ultra-high-definition display, in the future, the layout of common cathode energy-saving products with smaller dot spacing is the best policy.

        To sum up, there is still a long way to go for common cathode energy saving to enter the industry. According to the current national policy and the development needs of LED displays, energy saving products are the general trend, and it is understandable for enterprises to deploy common cathode energy saving. However, enterprises should also objectively look at the difficulties of common-yin energy saving entering the industry, whether the industry is mature, whether the production cost is affordable, and whether the return period is bearable. It should be weighed according to the company's own situation, objectively analyzed, and choose the development path that is most suitable for itself, rather than People say what they say.
