Because OLED lighting also has key obstacles such as service life, luminous efficiency, and cost in the short term, the industry believes that OLED lighting products should be introduced into mass production and commercialization stages, and it may take at least 1-2 years to be more than LED lighting. later.
OLED refers to the phenomenon of light emission caused by carrier injection and recombination driven by an electric field. The principle is to use ITO glass transparent electrode and metal electrode as the anode and cathode of the device respectively. Under a certain voltage, electrons and holes are injected from the cathode and the anode to the electron and hole transport layer, respectively, and then migrate to the light-emitting layer respectively. The encounter forms excitons to excite the luminescent molecules, which emit radiation after being irradiated. Radiation light can be observed from the ITO side, and the metal electrode film also functions as a reflective layer.
According to market research firm DisplaySearch, OLEDs have bright prospects in the development of display and lighting applications. Although only a few manufacturers are currently supplying OLED-related products, it is estimated that the output value of the global OLED industry in 2010 has reached the $1 billion mark. As more and more manufacturers gradually introduce mass production, which will increase the supply of OLEDs, the scale of the OLED market will continue to expand rapidly. In 2011, the output value has an opportunity to reach more than 2 billion US dollars, with an annual growth rate of 100%.
At present, the two main application markets of OLED are display and illumination, and the development of display applications is relatively fast. At present, there are many consumer electronic products such as mobile phones, MP3s, digital cameras, and car displays, which are introduced into PMOLED panels or AMOLED panels. As for OLED lighting applications, according to scholars' opinions, OLED lighting has energy saving, carbon reduction, mercury-free, no ultraviolet, no infrared, no high heat, no glare, light and thin, low driving voltage, smart dimming and soft flexibility. Other characteristics and advantages have been invested in the development of many international lighting brand manufacturers in recent years.
However, because OLED lighting still has key obstacles such as service life, luminous efficiency and cost in the short term, the industry believes that OLED lighting products should be introduced into mass production and commercialization stages, and it may take at least 1-2 years to compare with LED lighting. Later.
USB Cable :1.Type A: almost every USB cable has a standard flat rectangular interface at one end. Most computers have a usb-a port to connect to only one USB port.
2.Type-B: almost square connector for printers and other active devices connected to computers. They are not common now because most devices have been moved to smaller connections.
3.Mini USB: a smaller connector type that was standard for mobile devices before micro USB. It's not common today, but you'll see it on some cameras, PlayStation 3 controllers, MP3 players, etc.
4.Micro USB: the current standard for mobile and portable devices, even smaller than Mini USB. Although you can still find micro USB on smartphones, tablets, USB battery packs and game controllers, some have turned to usb-c
5.Type-C: the latest USB standard, which is a reversible cable, promises higher transmission speed and higher power than previous USB types. It can also take into account a variety of functions.
