On July 2, the DIC 2021 China (Shanghai) International Display Technology and Application Innovation Exhibition hosted by the Liquid Crystal Branch of the China Optoelectronics Industry Association (CODA) was grandly held at the Shanghai Pudong New International Expo Center. HBDX Optoelectronic Material Technology Group, the leader of China's optoelectronic display materials, made a major debut at the exhibition. Its independently innovative LTPS substrate material won the "Display Material Innovation Gold Award" in the "DIC AWARD 2021 International Display Technology Innovation Award" first set up this year.
It is understood that the "DIC AWARD 2021 Display Material Innovation Gold Award" aims to recognize and commend products or solutions that have outstanding contributions and important influence in various aspects such as the future development trend of display industry technology, product and technological innovation, and innovative applications. Industry insiders pointed out that this award accelerates the improvement of China's display industry ecological chain and opens a new chapter in innovation and upgrading.
The scale of China's panel industry in 2020 has leapt to the first place in the world, and China's display industry has achieved leapfrog development and has become an important pole of the global display industry.
The liquid crystal glass substrate is an important part of the display device and one of the key basic materials of the display industry. With the vigorous development of TFT-LCD, OLED and other products in recent years, the market size and demand for glass substrates have steadily increased, and higher performance requirements have also been put forward. LTPS glass substrate has high melting temperature and is difficult to form. It is the most difficult glass variety to manufacture in display substrates. Previously, it was mainly monopolized by international giants. Due to the iterative upgrade of display technology, LTPS glass substrates have become a "stuck neck" problem in the development of my country's high-end display industry.
The Hay Think team learned that due to the increase in display effect and screen refresh rate, it is necessary to use low-temperature polysilicon (LTPS) technology to prepare TFTs. The heat treatment temperature in the LTPS process is as high as 600-700℃, and the glass substrate will be irreversibly shrinked and deformed by the heat treatment, which will affect the quality of the display panel. Therefore, the LTPS process has stricter requirements on the temperature resistance, surface quality and dimensional accuracy of the glass substrate. Harsh.
Relying on its strong scientific research strength, HBDX is determined to help ensure the safety of the national display industry. The company broke the technological monopoly of international giants in the field of LTPS glass substrates. "G6 (G5.5 compatible) LTPS glass substrate development and industrialization project" won the first prize of provincial scientific and technological progress, marking the successful completion of LTPS process with high temperature The transformation, upgrading and upgrading of glass substrate products also represents a breakthrough in China's production technology in another key display material field.
The relevant person in charge of HBDX said that the company's LTPS process uses high-temperature glass substrates to achieve full coverage and mass production, filling the domestic gap, and has an immeasurable effect on the development of China's flat panel display glass substrate manufacturing industry and the improvement of the industrial chain. In addition, this product not only directly reduces the purchase cost of domestic panel manufacturers, but also significantly improves the bargaining power of core materials such as glass substrates with foreign suppliers. The hidden cost reduction brought by this can reach more than 100 million yuan per year.
HBDX fully covers the G5, G6 and G8.5 generations of TFT-LCD liquid crystal glass substrate products, and also has high-aluminum cover glass, curved glass, drop-resistant glass, optical film and other core optoelectronic display material production lines. The company has made breakthroughs in the technical fields of carrier glass, GOG technology, and drop-resistant glass. Various core optoelectronic display materials have achieved good linkage effects, effectively enhancing the core competitiveness in the field of optoelectronic display materials.
