According to foreign media reports, this year, the iPhone will use AMOLED screens (a type of OLED screen) for the first time, and the global AMOLED screens have also experienced tight production capacity. However, a technology market research institute recently said that China's domestic AMOLED screen manufacturers are still behind the South Korean "Samsung Display" in the technical level for several years. In the next five years, they will still not be able to obtain orders from international manufacturers such as Apple. The needs of mobile phones.
Taiwan Electronics Times Research Department pointed out recently that with the increasing market share of Chinese mobile phone manufacturers in the world, they will mainly supply from AMOLED screen manufacturers in China.
The above research institutes pointed out that Chinese screen manufacturers have been developing AMOLED technology for a long time, and another production line is under construction. It is estimated that by 2020, the total capacity of China's AMOLED screen manufacturers will reach half of the total capacity of Samsung Display and LG Display. .
Currently in the global market, four companies are preparing to compete for orders for Apple's mobile phone AMOLED screens, namely Samsung Display, LG Display, Japanese Display and Sharp Japan. Among them, Samsung currently has a monopoly advantage, and has already received orders for 100 million AMOLED screens for Apple's mobile phones in 2017. According to reports, Samsung's products for Apple are made of plastic, which means it may be a curved screen.
Compared with leading manufacturers, Chinese AMOLED screen manufacturers mainly need to overcome two technical obstacles: improve screen resolution and use plastic substrate technology. In these two areas, Samsung monitors are significantly ahead of Chinese companies.
Among Chinese manufacturers, Shanghai Hehui Optoelectronics will reach the level of Samsung Display in 2014 this year. Hehui Optoelectronics is about three years behind, while other Chinese manufacturers are about four to five years behind.
When producing AMOLED panels, the yield of volatile luminescent materials becomes a bottleneck, and the higher the screen resolution, the lower the yield.
Among Chinese manufacturers, only Huihui Optoelectronics and Xinli Optoelectronics can produce full HD AMOLED screens. It is expected that by the end of this year to the middle of next year, Kunshan Guoxian Optoelectronics, BOE, Tianma Microelectronics and other companies will be able to produce full HD. AMOLED screen.
In the second half of 2014, Samsung Display began to produce flexible AMOLED screens using PI (polyimide) materials. Chinese manufacturers have already introduced similar panel products, but it is not expected to be mass-produced by 2018.
Compared with Apple, Chinese mobile phone manufacturers have used OLED screens in their smartphones for a few years, but they are smaller. Compared with the LCD screen, the OLED screen has better picture quality, larger viewing angle, and more power saving. As the production cost of the OLED screen is gradually reduced, the outside world believes that in the fields of smart phones and large-screen TVs, OLEDs will gradually Replace the old LCD screen.
For Apple, the first launch of this year's OLED mobile phone will face the problem of insufficient supply capacity. So far, LG, Japan Display and Sharp have not yet achieved mass production and cannot jointly supply Apple. It is reported that Apple will adopt a step-by-step model. Only one of the three mobile phones in 2017 will adopt an OLED screen. By 2018, it is expected that all mobile phones will turn to OLED screens.
Although iPhone sales have fallen, Apple is still the most influential company in the global smartphone market. Once Apple abandoned the LCD screen with OLED screen, it is expected that the global mobile phone industry, including Chinese manufacturers, will switch to OLED quickly, which will aggravate the tight supply of global OLED screens.
According to sources quoted by the Taiwan Electronic Times, in 2017, as Chinese manufacturers such as Huawei, OPPO, and Vivo continue to increase handset production, key mobile phone parts in the world will be out of stock, and OLED screens “will definitely have insufficient supplyâ€. .
