The development of the TFT photoresist (TFT Array positive photoresist) industry is accelerating. The TFT-LCD and AMOLED fields are its largest demand ends.

TFT photoresist, also known as TFT Array positive photoresist, refers to the photoresist used in the Array segment of the manufacturing of TFT-LCD display panels or AMOLED display panels. There are many types of TFT photoresists, including Yocta process photoresist, TFT patterned photoresist, ITO patterned photoresist, protective insulating layer photoresist, and OLED Array flat layer photoresist. In recent years, with the accelerated development of the display panel industry, my country’s TFT photoresist market demand has become increasingly strong.

The core raw material of TFT photoresist is novolac phenolic resin. Novolac resin has the characteristics of good water resistance, non-flammability, acid resistance, etc., and is widely used in the photoresist production process. In the early stages of industry development, my country’s novolac resin was highly dependent on imports due to factors such as high technical barriers and high production costs. In recent years, driven by positive factors such as national policy support and the improvement of independent research and development capabilities of local companies, the localization process of my country’s novolac resin market has accelerated. Shengquan Group has the ability to batch supply novolac resin for TFT photoresists, which will provide A good foundation has been laid for the development of the TFT photoresist industry.

          TFT photoresist is mainly used in TFT-LCD display panels and AMOLED display panels. As the prosperity of the downstream industry increases, the global TFT photoresist market demand is increasingly strong. According to the “2023-2028 China TFT Photoresist (TFT Array Positive Photoresist) Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center” shows that global TFT photoresist sales will reach US$490 million in 2022, setting a record high. In terms of the local market, as the global display panel industry gradually shifts to my country, my country’s TFT photoresist market space will further expand.

The global TFT photoresist market is dominated by overseas companies, including Tokyo Chemical Industry Co., Ltd. (TOK) of Japan, Merck of Germany, and Dongjin Co., Ltd. of South Korea. The above three companies dominate the world. Nearly 95% of the market share. Germany’s Merck is the world’s largest supplier of TFT photoresist, accounting for nearly 50% of the market.

In terms of the local market, some mid- to low-end TFT photoresists in my country have been domestically produced, but high-end TFT photoresists still need to rely on imports. In the future, as the technological innovation level of local companies improves, the development speed of my country’s TFT photoresist industry will be Keep accelerating. Tongcheng New Materials, Rongda Photosensitive, Jingrui Technology, Feikai Materials, Yongtai Technology, etc. are the main players in my country’s TFT photoresist market. Beixu Electronics, a subsidiary of Tongcheng New Materials, is a representative company of TFT photoresist in my country, occupying nearly 20% of the Chinese market.

          Industry analysts said that TFT photoresist, as a photoresist for display panels, has broad application prospects. In recent years, with the growth of market demand, TFT photoresist sales have continued to increase. However, at present, overseas companies still dominate the global TFT photoresist market, and local companies urgently need to increase investment in research and development to promote the development of the TFT photoresist industry in a high-end direction.
