Yellow polyimide (YPI) can be used to produce flexible OLED display screens. Dinglong Co., Ltd. is a leading company in my country

​​​​Yellow polyimide (YPI) is a subdivided product of polyimide, which refers to an organic polymer material that contains imide rings on the main chain and has a golden or yellow appearance. Yellow polyimide has the advantages of good chemical stability, high/low temperature resistance, chemical corrosion resistance, and good mechanical properties. It can be used to manufacture thin film products and is widely used in the field of display panels.

​ ​ ​ Yellow polyimide film is a yellow polyimide end product. Its main preparation methods include casting and stretching, casting, dipping, etc. The tape-casting stretching method is an emerging method for preparing yellow polyimide films. This method has the advantages of good finished product quality and high production efficiency. The thermal stability and electrical properties of films made using this method are greatly improved; the tape-casting method It can be used to prepare films with good mechanical properties and good uniformity; the dipping method is a traditional preparation method for yellow polyimide films. This method has shortcomings such as low yield and poor quality of finished products, and is gradually being used by emerging preparation methods. substitute.

According to the “2023-2028 China Yellow Polyimide (YPI) Industry Market In-depth Research and Development Prospects Forecast Report span>》shows that yellow polyimide is mainly used in the field of display panels and is the main material for flexible OLED display screens. Flexible OLED display screen refers to a screen that can be bent and folded at will. It has the advantages of good three-dimensional image display effect, low power consumption, small size, and lightweight. It can be used to manufacture smart wearable devices, high-end smartphones, wall TVs and other products. In recent years, as the global display panel industry has gradually shifted to my country, my country’s flexible OLED display screen market prospects have continued to improve. Yellow polyimide film can replace the glass material of traditional rigid screens and be used to produce flexible OLED display screens. As downstream demand grows, its market space will further expand.

Yellow polyimide is a high-performance polyimide. For a long time, due to factors such as high technical barriers and high production costs, my country’s high-performance polyimide has been highly dependent on imports. Hubei Dinglong Holdings Co., Ltd. is my country’s leading yellow polyimide company. It has independent research and development capabilities for high-performance polyimide and is the only company in my country with large-scale production capabilities for yellow polyimide. At present, Dinglong Co., Ltd. has reached cooperation with many display panel manufacturers in my country such as Huaxing Optoelectronics and Wuhan Tianma to supply yellow high-temperature-resistant polyimide products in batches. According to the financial report of Dinglong Co., Ltd., the company will achieve revenue of 2.72 billion yuan in 2022, a year-on-year increase of 15.5%.

​​  Industry analysts said that as a high-performance polyimide, yellow polyimide has broad application prospects in the field of display panels. With the growth in market demand for flexible OLED display screens, the prosperity of my country’s yellow polyimide industry has further improved. In terms of market competition, my country’s yellow polyimide industry is highly concentrated, and Dinglong Co., Ltd. occupies a dominant position in the Chinese market.
