なぜTFT-LCD LCDスクリーンが主流のディスプレイスクリーンになることができるのですか？
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.
10年以上前、OLEDはTFT-LCDに取って代わる可能性が非常に高いと考えられていました。 重要な利点の1つは、OLEDの色域が110％に達する可能性があるのに対し、従来の液晶ディスプレイの色域はわずか70％であるということです。 ただし、量子ドットバックライトを使用した後、TFT - LCDの色域は120％に達する可能性があり、これは色再現においてOLEDよりも有利です。 TFT - LCD業界は、今後もディスプレイ業界の主流であり続けることがわかります。 2005年、中国本土のディスプレイパネル製品の生産量は世界の生産量の1％未満でした。 2017年、TFT-LCDの出力は1億平方メートルに達しました。 2022年には、2億平方メートルに達するでしょう。 私の国は、新しいディスプレイ産業の規模で最も急速に成長している国になり、TFT-LCDの生産能力は世界で1位にランクされています。
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.
