Flat panel display industry survey: LCD TV fades out of LED TV into the mainstream

lcd TV fades out of LED TV into the mainstream

we know that the national economy is composed of various industries, such as automobile, steel, banking, catering, etc., which are interrelated industries. Only after understanding the rise and fall of various industries can we understand the operation of the overall economy. Each industry is a role in the economic arena. Our finance and economics channel will gradually launch a series of industrial investigation programs, select those important pillar industries and industries that investors and consumers are very concerned about, and conduct investigation and report in combination with important developments. Today, let's focus on the flat panel display industry. We are all familiar with LCD TV, but LCD TV is also divided into several categories, and there are advanced and backward. We have learned that LCD flat-panel TVs, which have just entered the home appliance market for about five years, are facing the fate of delisting. The so-called LCD TVs are short for LCD monitors. By the beginning of next year, you may no longer see LCD flat-panel TVs in first tier cities, but will be replaced by LED backlight TVs. The fundamental reason is that LCD flat-panel TVs consume too much energy. Let's watch the report together

lcd and led belong to LCD TV, but the backlight used by LCD is fluorescent tube, while LED is light-emitting diode, which is generally called "LED backlight LCD TV". It is superior to LCD TV in terms of service life, color display, especially energy consumption. Taking a 32 inch TV as an example, the energy consumption of LED backlit TV is about 60 watts, while that of LCD TV is about 80 watts, which is more than 30% higher

consumers: they always choose LED TV when buying

after domestic enterprises have mastered the core technology of LCD glass substrate, the price of LED backlight TV has dropped significantly, and some are even lower than LCD TV. It can be said that LCD TV has been declining

according to the major home appliance stores in Beijing, the market share of LED backlit TV has reached 90% at present, and even surged to 95% recently. However, LCD TV has become neglected. In major shopping malls, LCD TV is being cleared at a minimum of 50% discount. Retailers say they are reducing their purchases of LCD TVs. At the beginning of next year, LCD TVs may disappear in first tier cities

breakthrough in domestic LCD glass substrates without scale

we also know that the so-called LED TV should be called LED backlight TV, which is also a kind of LCD TV, but the light source has become a light-emitting diode, and the LCD panel is still a traditional LCD panel. We are not unfamiliar with LCD panels. Tablet computers, smart phones, digital cameras and so on are inseparable from LCD panels. When it comes to the upstream of liquid crystal panels, that is, liquid crystal glass substrates, this is a bit professional. Liquid crystal glass substrates account for% of the cost of liquid crystal panels, which has laid a solid foundation for Chinese automobile enterprises to break through the bottleneck of VOCs control technology. The global market of this product is monopolized by four multinational companies including Corning. However, domestic liquid crystal glass substrates have begun to be supplied in batches. The industrial pattern of flat panel display began to change

recently, two 8.5 generation LCD panel lines independently built by BOE and csot have all entered the production stage, alleviating the long-standing situation of "lack of core and few screens" in China's flat panel display industry. However, the liquid crystal glass substrate with the highest technical content and profit margin can not be produced in China

wangjunming, director of Henan liquid crystal glass engineering technology research center: the key material has no self-control ability. This is the case with foreign companies. If you can't produce it yourself, you will have to ask for a high price. You can't live without it

now, Zhengzhou Xufei optoelectronics has built the fifth generation LCD glass substrate production line, realizing a mass production of 800000 square meters. The 0.5mm generation 4.5 liquid crystal glass substrate production line of Chengdu zhongoptoelectronics has also started wholesale supply with the R & D advantages of Zhejiang University, Ningbo Institute of materials, Chinese Academy of Sciences, Zhejiang Tsinghua Changsanjiao Research Institute and other universities and institutions. However, up to now, only a few production lines of domestic LCD substrate glass can be mass produced. It is understood that the annual output of one LCD panel production line is 1.2 million pieces, and one panel requires two glass substrates. Such a panel production line needs at least 2.4 million glass substrates a year. According to the annual output of one glass substrate production line of 550000 pieces, one panel production line needs five glass substrate production lines. There are nearly 20 panel production lines in China, and at least 100 glass substrate production lines are required

lizhaoting, chairman of Dongxu group: therefore, this kind of impact requires our real support for the industry. Guizhongwang, which needs to make its scale into 30 or 40 lines, has participated in the optimization design of component structure, material experiment, two-dimensional drawings, section improvement, sample vehicle trial production and other working models. For example, the real support for its anti-skid performance can be confirmed by testing the friction coefficient of the floor (brick)

in the view of insiders, it is very urgent to expand the LCD glass substrate, because in addition to the emerging LED backlight TV, new TV technologies such as OLED and other display technologies are also brewing. It does not need backlight, and uses thinner organic material coating and glass substrate. Japanese and Korean display panel giants have been increasing their R & D investment in OLEDs in recent years, and even this new technology is inseparable from the liquid crystal glass substrate

Chenjun, senior engineer of Henan Engineering Laboratory: no matter what kind of display devices, liquid crystal, plasma or OLED, glass substrates are used. As long as we master this technology, we will have a say in the whole industry chain
