>> OLED fancy attack LCD panel opens a difficult survival mode 16th,Oct,2018
The price increase of LCD TVs has not stopped. In the past six months, TVs from 40吋 to 55吋 have increased by 300-500 yuan, especially Internet TV manufacturers with low profits but at the guise of the Internet. Xiaobian has two friends who originally planned to buy "high cost performance" Internet TV. Now they are holding a wait-and-see attitude in the face of rising prices, and want to wait until the price drops down and buy again. According to the current situation, the possibility of LCD TV price cuts in the short term is negligible. The reason for the price increase of LCD TVs can be attributed to two points. First, the general trend of RMB exchange rate fluctuations and inflation has led to an increase in raw material costs, and liquid crystal panels have also risen. Second, the panel makers have upgraded their industries, and the shift in focus has led to an increase in the price of LCD panels.
The display industry is actually an industry that is everywhere, because it is a strategic resource in the technology industry. Almost all personal consumer electronics products need to be directly or indirectly related to the display.
Liquid crystal display technology has passed its golden age. Since the second half of last year, the global LCD panel industry has experienced abnormal cyclical fluctuations. As the recognized next-generation display technology OLED, as the consumer market gradually becomes more and more demanding, it is increasingly valued by mainstream panel manufacturers.
OLED fancy attack LCD panel opens a difficult survival mode
Why is OLED gradually becoming mainstream? This is closely related to Apple's use of OLED display technology in new products and the urgency of the VR industry. In terms of large-screen display, OLEDs are also closely related to liquid crystals. This year, the large-screen OLED camp has more old TV manufacturers such as Sony and Panasonic. As OLEDs have made breakthroughs in key technologies, their advantages in the display field are becoming more and more obvious, and the addition of the whole industry will also cause their costs to drop.
LG Display, the global leader in the panel industry, will build the world's largest 10 generation OLED production base in Paju, South Korea, or mass-produce large-size OLED panels and small and medium-sized flexible OLEDs, which are expected to be completed in the second quarter of 2018. Samsung is not willing to show weakness, shut down some LCD factory lines, and concentrate on expanding OLED production capacity. LGD's current OLED line mainly focuses on large-size TV panels, while Samsung mainly focuses on the investment of AMOLED panels to meet the needs of smartphones.
Domestic panel makers are not afraid to slack off. It is rumored that Sharp will invest hundreds of billions of dollars in OLED panel factories; BOE already has two OLED production lines and one OLED test line; Tianma and Visionox have three OLED production lines; Guoxian Optoelectronics has a 6th generation AMOLED production line also established in Hebei in. Almost all domestic panel makers are trying to grasp the opportunity of the overall transformation of the display industry, and strive to lay out the OLED panel. The data shows that the market share of OLED panels has also increased significantly.
In addition to the transformation of the enterprise itself, a large amount of capital is also being injected into the emerging display industry. Some cutting-edge technologies such as printed display technology, flexible color electronic ink screens, etc. have all received attention from capital ventures.
Print OLED, the coolest way to replace LCD
Since everyone is transforming into OLED, when can we really replace LCD technology? If it is completely replaced, it is really difficult. After all, LCD has a very deep root in all walks of life. However, OLED has the ability to enter the class in the future may become the ultimatum of LCD.
That is the printing of OLEDs. It is also an emerging display technology developed by the giants such as BOE, TCL, Samsung and LG. In principle, it is also an OLED technology, but it is recognized as an effective way to solve the high cost of OLED and achieve a large area. We all know that OLEDs have self-illuminating properties, using very thin organic coatings and glass substrates. Printed OLEDs use advanced printing equipment to “print” organic materials onto glass substrates like newspapers, which is more efficient than traditional evaporation techniques.
How to “print” like a newspaper? We all know that when dyeing patterns on T-shirts, there are two methods of inkjet printing and screen printing. Printed OLEDs are also divided into inkjet printing and screen printing. At present, the mainstream direction is concentrated on inkjet printing. The inkjet printing device has a plurality of printing heads, each of which has a plurality of micro-nozzles, and accurately deposits red, green and blue luminescent material solutions in the isolation column grooves of the ITO glass substrate, and the solvent volatilizes to form a nano-thin layer. Forming a luminescent pixel.
The nozzle is made of special piezoelectric ceramic. It can control the thickness of the luminescent layer by controlling the voltage applied and the length of time on the ceramic to control the thickness of the luminescent layer. Since this is a complete digital technology, it does not require any machining. Through such a printing method, it is expected to greatly reduce the cost of OLED fabrication, extend the life of OLED materials, and at the same time improve the yield of large-size screens.
Printed OLEDs are so valued, and one important reason is that it is closely related to flexible displays. Think about printing a screen like a printed newspaper. Can the screen be bent as casually as a newspaper?
Although this technology is still in the early stage of development, all panel makers and TV manufacturers have been full of strength. Especially domestic manufacturers have started in Japan and South Korea in the LCD and OLED era. The printing technology just gave the domestic manufacturers the same platform. opportunity. In the past few years, TCL has repeatedly made plans to consolidate the upstream industrial chain, and signed strategic agreements with DuPont and Sumitomo Chemical of Japan to print OLEDs. Japan's JOLED and South Korea's Samsung and LG are actively introducing inkjet printing processes. Presumably, the future is a scene full of flowers.
Summary: Lian Po Lao, can still eat rice? With the rise of emerging display technologies, liquid crystal displays will eventually enter the next year. The evolution of technology has become the norm. Whoever has an early insight into the business path brought about by technological change will seize the opportunity. As a consumer, of course, I want to see better and cheaper products. When money is getting less and less valuable, I hope that new technologies will bring costs down.
