टीएफटी-एलसीडी एलसीडी स्क्रीन मुख्यधारा की डिस्प्ले स्क्रीन क्यों बन सकती है?
Mar 25, 2022
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.
एक दशक से भी अधिक समय पहले, OLED को TFT-LCD की जगह लेने की बहुत संभावना थी। महत्वपूर्ण लाभों में से एक यह है कि OLED की क्रोमैटिकिटी सरगम 110 प्रतिशत तक पहुंच सकती है, जबकि पारंपरिक लिक्विड क्रिस्टल डिस्प्ले का क्रोमैटिकिटी सरगम केवल 70 प्रतिशत है। हालांकि, क्वांटम डॉट बैकलाइट का उपयोग करने के बाद, TFT-एलसीडी की वर्णिकता सरगम 120 प्रतिशत तक पहुंच सकती है, जो रंग प्रजनन में OLED से अधिक फायदेमंद है। यह देखा जा सकता है कि टीएफटी-एलसीडी उद्योग अभी भी आने वाले लंबे समय के लिए प्रदर्शन उद्योग की मुख्य धारा रहेगा। 2005 में, मुख्य भूमि चीन में डिस्प्ले पैनल उत्पादों का उत्पादन वैश्विक उत्पादन के 1 प्रतिशत से भी कम था; 2017 में, TFT-एलसीडी का उत्पादन 100 मिलियन वर्ग मीटर तक पहुंच गया; 2022 में, यह 200 मिलियन वर्ग मीटर तक पहुंच जाएगा। मेरा देश नए प्रदर्शन उद्योग के पैमाने में सबसे तेज वृद्धि वाला देश बन गया है, और टीएफटी की उत्पादन क्षमता -एलसीडी दुनिया में पहले स्थान पर है।
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.
