Demand for smart watches broke out OLED panels drive indium consumption

- Mar 29, 2019-

With the rapid growth of smart watches, OLED has once again found an opportunity for outbreaks, and the demand for ITO targets, a key material for OLED touch screen production, will also grow steadily, and the demand for rare metal indium is promising for a long time.


In the OLED market report released by DisplaySearch, a market research firm, a group of figures has caused widespread concern. According to the report, shipments of OLED panels (including PMOLEDs and passive OLEDs) for smart watches increased significantly to 4.98 million units in the first quarter of this year, exceeding 4.76 million units last year, compared with 1.67 million LCD panels for smart watches. The film is nearly 200% higher.


Among the 4.98 million pieces, the leading company LG Display shipped 3.55 million pieces, and the market share reached an overwhelming 71%. The rapid growth of smart watches adds another important weight to OLED acceleration.


The industry believes that the smart watch market and the TV market will promote and complement each other. Under the promotion of dual engines, the speed of OLED popularization will exceed the previous expectations. OLED, also known as organic light-emitting diode, has self-luminous properties, uses a very thin coating of organic materials and a glass substrate. When there is current, these organic materials will emit light, and the OLED display screen has a large viewing angle and can save Electrical energy.


The OLED panel is made by sputtering a thin, transparent and semiconducting indium tin oxide (ITO) onto the glass to form a transparent conductive film connected to the positive electrode of the power supply, plus another metal cathode. The structure of the sandwich. Indium tin oxide is a compound of indium oxide and tin oxide. Its main characteristics are electrical conduction and optical transparency.


Metal indium is a rare metal, mainly derived from by-products of lead and zinc smelting, and is refined to form indium ingots. Indium ingots are mainly used in the production of ITO targets (for the production of liquid crystal displays and flat screens) due to their high optical permeability and electrical conductivity. This use is the main consumption area of indium ingots, accounting for 70% of global indium consumption. In addition, indium is also widely used in high-tech fields such as electronics industry, aerospace, alloy manufacturing, and solar cell new materials. China's indium reserves rank first in the world, and the state attaches great importance to its storage. The Pan-Asian Nonferrous Metals Exchange focuses on the spot trading and commercial storage of rare metals. Since its inception, it has listed metal indium as a listed product. Today, its inventory has reached more than 3,600 tons, equivalent to more than five years in the world. Yield. It is foreseeable that in the future, with the increasing demand for OLED panels, Pan Asia will become an important supplier of indium raw materials and play a role as a market stabilizer.


At present, the market for smart watches has just opened, and the growth potential is still huge. The outbreak of the smart watch market may drive more wearable devices and smart home appliances to choose OLED panels, and small and medium OLED panels will usher in more opportunities. At the same time, as the main raw material of OLED, rare metal indium will also usher in a new consumer and investment boom. By then, relying on sufficient indium inventory and leading position in the rare metals industry, the Pan-Asian Nonferrous Metals Exchange will gradually Infiltrate the role of the platform into the downstream industry.
