Perché lo schermo LCD TFT-può diventare lo schermo di visualizzazione mainstream?

  The reason why the TFT-LCD industry can become the mainstream of the display industry is that the industry benefits from the perfect combination of semiconductor technology, liquid crystal material technology, and active light-emitting technology. The initial breakthrough of liquid crystal display was in the field of liquid crystal synthesis, and liquid crystal display began to break through from notebook computers. The successful modern liquid crystal display applied the concept put forward by two Soviet scientists in 1927, that is, the transition time of liquid crystal molecules to rotate after lengthening is only milliseconds. Driven by semiconductor technology, the TFT-LCD industry is getting bigger and better, and it has won many battles in the competition with other display technologies.

Più di un decennio fa, si riteneva molto probabile che OLED sostituisse l'LCD TFT-. Uno dei vantaggi importanti è che la gamma di cromaticità dell'OLED può raggiungere il 110 percento, mentre la gamma di cromaticità del tradizionale display a cristalli liquidi è solo del 70 percento. Tuttavia, dopo aver utilizzato la retroilluminazione a punti quantici, la gamma cromatica dell'LCD TFT- può raggiungere il 120 percento, il che è più vantaggioso dell'OLED nella riproduzione dei colori. Si può notare che il settore degli LCD TFT-rimarrà ancora il mainstream del settore dei display per molto tempo a venire. Nel 2005, la produzione di pannelli di visualizzazione nella Cina continentale rappresentava meno dell'1% della produzione globale; nel 2017 la produzione di TFT-LCD ha raggiunto i 100 milioni di metri quadrati; nel 2022 raggiungerà i 200 milioni di metri quadrati. il mio paese è diventato il paese con la crescita più rapida nella scala del nuovo settore dei display e la capacità di produzione di TFT-LCD è al primo posto al mondo.

     The development trend of my country's TFT-LCD industry is good, which is inseparable from the support of national policies, the hard work of a group of outstanding entrepreneurs, and the support of China's booming economic fundamentals. my country's mobile phones, computers, and televisions account for the largest share of the world market. In 2019, China became the largest display production base, with industries mainly concentrated in the Yangtze River Delta, Pearl River Delta, Beijing-Tianjin-Tangshan and Chengdu-Chongqing-Hubei regions. The reason why China can gain a place in the display industry where foreign companies have fully competed is because my country has carried out independent innovation while seizing market opportunities. The shipment scale of low-temperature polysilicon display panels and metal oxide display panels in my country ranks first in the world. Technologies such as gate driver integrated circuits, narrow borders, low power consumption, built-in touch control, and transparent display are being applied to TFT-LCD. At present, the innovation of stacked-screen TVs and Mini LED-backlit TVs has made LCD TVs comparable to laser TVs and OLED TVs, which has led to the active upgrading of color TV sets and reduced the production capacity of upstream LCD panel companies. excess risk.

     In the new era when my country's TFT-LCD production capacity ranks first in the world and the industrial base has obvious advantages, we should insist on independent innovation and further develop the TFT-LCD industry. The innovation of display applications not only brings more new experiences to public life, but also further changes the social life style and accelerates the process of scientific and technological revolution. 5G will bring huge development opportunities to the display industry. The 5G era is an era of great development of the information industry. Semiconductor display technology will continue to be upgraded. 8K and ultra-high definition have become important development trends in the display industry. They are the first wave of the information industry to promote economic development. Flexible display technology will also usher in new development opportunities.
