With the development of technology and the improvement of production capacity, coupled with the vigorous development of smart hardware industries such as smart phones, wearable devices and VR, new demands have been placed on displays. Compared with LCD screens, the biggest feature of OLEDs is that OLED screens have self-illuminating characteristics. Energy saving, ultra-thin, and flexible (flexible) are some of the main advantages. OLEDs can be divided into active according to different driving forms. Both active and passive, active is the AMOLED technology we often see. Samsung has adopted this technology since GALAXY S1; passive type is also called PMOLED, which is mainly used on large-size screens such as monitors and TVs.
With the development of Samsung AMOLED screens and the increase in production capacity, more and more domestic mobile phone manufacturers have begun to use this latest technology, such as OPPO R9, Huawei P9 Plus, Vivo Xplay5 and one plus mobile phone 3, etc. . In addition to being mainly used on displays, OLEDs also have certain applications in lighting.
Although the OLED screen has many advantages and advantages, it also has certain shortcomings in the development process, such as production process and service life. Compared with the more mature screen technology of LCD, OLED is limited to the production line and Due to process technology and other aspects, although the cost of raw materials has gone down, it is still higher than the LCD screen. In addition, in terms of service life, compared with the use of LCD for at least 10,000 hours, the lifetime of OLED is only half of its 5,000 hours. But users don't have to worry about it. There are more than 200 years of conversion in 500 hours, which is enough for users to use.
Apple to Samsung to add orders to OLED screen manufacturers or will usher in spring
In terms of OLED technology, Samsung and LG have a production capacity of 92% of the world. According to foreign media, Samsung Electronics and Apple recently signed an agreement to supply an additional 60 million OLED panels for the iPhone launched this year, worth about $4.35 billion. Together with the relevant agreement signed in April 2016, Samsung Electronics will provide 160 million OLED panels to Apple in total, amounting to US$11.31 billion. At present, 80% of Apple's OLED screens will be provided by Samsung. In addition, Apple has recently negotiated with domestic screen supplier BOE, and it seems that it intends to include BOE in Apple's suppliers. According to the global sales of iPhones every year, it is difficult for Samsung to complete the supply of raw materials for Apple's mobile phones. After all, its own mobile phones are also needed, so the remaining 20% ​​of the screen supply will be available from JDI, BOE and other manufacturers.
If Apple adopts OLED curved screen technology, this will definitely play a huge role in promoting the OLED industry. With the position and influence of Apple's mobile phone in the mobile phone industry, Apple's involvement will inevitably lead to other mobile phone manufacturers emulating. Greatly promote the development of the OLED industry.
VR virtual reality industry will also become an important driving force for the development of OLED
With the development of the VR industry, it has also greatly driven the development of OLED screens. In addition to experiencing the immersive sensory experience of VR devices, dizziness has caused headaches for many people. The cause of VR stun is mainly delay, because the refresh rate of VR equipment is only less than 20ms before it will have dizziness. The refresh rate of traditional LCD screens is generally greater than 30ms, and the response time of OLED is one thousandth of LCD, so OLED screen is one of the important solutions to solve the anti-stun effect of VR equipment. OLED screens are standard on VR device displays. The VR virtual helmets HTC vive and PlayStaTIon VR, which are currently on the market, all adopt OLED screens. The development of the VR industry will also drive another important expansion of the OLED screen application field.
to sum up
Compared to LCDs, the biggest advantage of OLED screen technology is flexibility. OLEDs can make smartphones thinner, lighter, and foldable, which is exactly the same as the demand for thinner, lighter, and foldable mobile phones. The flexible nature of OLED technology will also revolutionize the way display is changed, such as naked-eye 3D technology. In 2017, more display devices will adopt OLED technology, and OLED will usher in the “spring†of rapid development.
