Why are OLED LCD displays widely used in the market

With the advancement of technology, our phones are becoming thinner and longer. Have you ever fantasized about your phone being able to bend or even fold? These products have only been seen in movies, but now with the emergence of OLED displays, this may be possible in the future. Not only mobile phones, but also tablets that can be folded for transportation would be more convenient to carry? So let's first understand what OLED is.

OLED, also known as organic light-emitting diode, is a new type of light-emitting diode based on the electroluminescence effect of organic materials. LCD is a widely used liquid crystal display. With the maturity of OLED technology and the decrease in cost, OLED is expected to replace existing LCD technology in the future and become the dominant technology for upgrading next-generation display technology.

What are the advantages of OLED compared to LCD?

OLED is thinner, more energy-efficient, faster in response, has lower cost of scale, and can display curved and flexible surfaces compared to LED. After mass production, the cost of OLED is 30% lower than that of LED.

OLED has so many advantages compared to LCD, why hasn't it been widely used in the market yet?

Although OLED has many advantages mentioned above, which make it highly likely to become the new generation mainstream display technology in the future, there are still some problems that restrict the widespread promotion of OLED.

The price is relatively high, especially on large-sized TVs, which is significantly higher compared to LED TVs of the same specifications, affecting consumers' purchasing decisions.

The yield rate is low, which is one of the important indicators to measure the maturity of panel production lines and has a significant impact on production costs. Therefore, the low yield rate is also one of the main reasons for the high cost of OLED currently.

has a shorter lifespan. The OLED currently used in mobile phone displays can maintain 5000 to 10000 hours, while OLED TVs must maintain at least 30000 to 50000 hours.

Insufficient production capacity hinders the development of terminal manufacturers. Currently, the supply of OLED is mainly controlled by Samsung alone. Insufficient production capacity will cause concerns among terminal brand manufacturers about supply safety, which will restrict the greater use of OLED products.

Why is it still said that OLED replacing LCD is a big trend?

Apple leads the way. Apple will use OLED screens on iPhones in 2017. Apple has a huge influence on the smartphone industry and supply chain, leading the technology trend multiple times. Its involvement has brought about significant changes in the entire OLED industry chain, and various manufacturers attach great importance to it and are laying out their strategies.

LG and Samsung's OLED leader layout. In February 2016, Samsung announced plans to invest 4 trillion Korean won (approximately 3.6 billion US dollars) to build a new OLED factory. According to the Korean Herald, Apple and Samsung have signed an agreement, with the latter providing Apple with approximately 100 million 5.5-inch OLED panels worth 3 trillion Korean won (approximately 2.59 billion US dollars) in 2017. The contract is valid for at least 3 years, meaning until 2018 and 2019. On July 23, 2015, LG announced that it would invest 150 trillion Korean won in the Guiwei factory in Gyeongsangbuk do to build a 6th generation flexible OLED production line with a planned monthly production capacity of 7500 glass substrates. The production is scheduled to begin in the first half of 2017.

In addition, the most suitable screen for smart devices represented by VR devices is OLED. The development of VR cannot be separated from the popularity of OLED, which will drive the explosion of OLED demand; BOE, Samsung LG、 The production of OLED production lines by major panel manufacturers such as Sharp has stimulated a significant increase in OLED panel output, directly driving a surge in demand for upstream OLED materials; Chinese companies have made technological breakthroughs in OLED materials and successfully achieved import substitution; Large scale application of quantum dot materials in China, breakthrough progress in QLED inkjet printing technology.
