Samsung display uses 0.4t glass in the field of large screen TV

the whole display panel industry is trying to improve 0. Production yield of 4T (mm) ultra-thin glass substrate. Recently, Samsung monitors began to set 0. 4T glass is used for large screen TVs, and no enterprise has used it on large panels before. Many people believe that Samsung's move can reduce the cost of curved TV panels by one level and improve the performance by one level

not long ago, Samsung monitors began to use 0 on large TV LCD panels. 4T glass substrate, originally 0. 4T glass is only used on small and medium-sized it panels, such as notebooks, display devices and other products. Many panel manufacturers - LG display, qunchuang, Youda, BOE and others - currently use glass substrates with a thickness of 0. 5 to 0. 6T。 SamSung monitor is the first to use 0 on a large TV panel. 4T glass enterprises. At first, the progress was not smooth, because it faced the problem of low yield. In the first quarter, Samsung's LCD business suffered a huge operating loss

previously, panel manufacturers poured hydrofluoric acid on glass substrates and then used a unique "weight loss" process to make 0. 4T glass substrate. Manufacturing ultra light and ultra-thin glass substrates is very important, because to keep up with the explosive growth of all new energy vehicles, it can improve the portability of visibility, intelligence, tablets, notebooks and other products

if 0 is used on the 8th generation or higher production line. When 4T technology is used to produce mother glass substrate, the glass substrate will be bent. As the substrate is too thin, it may break with the increase of bending amplitude. In the later process, the reducer is a power transmission mechanism in the tension machine, which is more difficult, such as scribing when cutting the panel, installing modules, etc. Panel manufacturers have no choice, they are difficult to improve the yield in the short term

the industry believes that Samsung display has chosen 0. 4T glass substrate to improve the panel performance of curved TV. As the thickness of the glass substrate decreases, its fusion ratio will rise, and the display screen will be clearer and brighter, using less power. Compared with smartphones and notebooks, although the competition for the thickness and weight of TV panels is not so fierce, people have begun to favor thinner and lighter TVs. Due to 0. 4T TV glass substrates do not need to be treated by an independent "weight loss" process, which can reduce the cost of post-processing during production, thus turning them into competitive advantages

the current curved TV is made of physically curved flat panel, which is different from the curved screen of intelligent and other products. In the bending stage, special equipment is required to correct the panel. For example, if you want to optimize the curved screen, you need to add additional pixels, and you also need to use technology to spread the light evenly on the whole screen

the interior environment of the car has become the focus of general concern when consumers buy cars
