Galaxy Fold re-release looks set to be another PR disaster for Samsung
ZDNet’s Adrian Kingsley-Hughes tells Karen Roby that Samsung should have let the Fold die rather than reanimate its corpse for yet another kicking. Read more: https://zd.net/2l6y8yR

Samsung Display will invest a whopping 13.1 trillion won ($11 billion) over the next five years to produce Quantum Dot (QD) displays, the company announced.

The South Korean tech giant will create a new line, dubbed Q1, that will be built at its existing display factory in Asan, located in South Korea’s South Chungcheong Province.

Production for the Q1 line will begin in 2021, which will consist of producing 65-inch QD displays with a monthly capacity of 30,000 8.5th generation substrates.

Concurrently, existing Liquid Crystal Display (LCD) production lines will also be sequentially turned into QD display lines with the goal of expanding production output further for QD displays by 2025.    

Samsung will spend 10 trillion won in building the factories and 3.1 trillion won for research and development. Researchers and staff currently working on LCD will now put their focus on QD displays as well, the South Korean tech giant said.

The company did not mention the specific technology for these QD displays, but it is very likely a combination of quantum dot and organic light emitting diode (OLED) technology, or QD-OLED. It is unclear what commercial name Samsung will designate for the displays when they hit the market.

Do or die

According to company insiders, the development of QD-OLED technology is still in progress. Development for QD-OLED technology will proceed concurrently with the construction of the facilities and production equipment that will be used for its eventual commercialisation. Production for the technology is expected to begin in 2021, and commercial products using the display will likely enter the market in 2022.

Planned spending indicates that Samsung Display’s production capacity, when it goes live, will likely be larger than its chief rival LG Display. LG is currently the sole producer of OLED panels for TVs. This will give Samsung Display an advantage in terms of pricing for display panels, which will make it easier to woo TV set-makers, including its own affiliate Samsung Electronics. Samsung Display will also most certainly attempt to entice LG Display’s clients, which includes Sony, much to the latter’s ire.

However, the yield rate and quality of the display panels will have to be up to scratch for it to be approved by Samsung’s Electronics Visual Display (VD) Business, which as a set-maker, is higher up in the value chain within the Samsung Group.

The VD business is also investing in ways to improve the resolution of LCD panels for its QLED brand of TVs as well as developing MicroLED technology, so QD-OLED will either have to offer superior resolution or better prices.

Then there is the matter of burn-in or permanent image retention, a problem that has previously plagued LG OLED TVs. Samsung Display’s production method is different from that of LG Display’s as it uses blue pixel diodes as light emitters, while using red and green QD colour filters. Although, Samsung’s commercial viability is yet to be tested in the market, so we will have to wait a couple of years to see the effectiveness behind Samsung’s technology in preventing burn-in.

Apple and China

The company’s QD-OLED investment plan is largely a reaction to two recent developments: Stagnating growth in smartphone markets and the rise of China.

Samsung Display controls over 90% market share in the mobile OLED space, dubbed as AMOLED by the company. It has been a gold mine for the company over the past couple of years, with the company’s displays used by Samsung Electronics, Apple, and Huawei.

Slowing growth of smartphones has lowered profitability for Samsung Display as of late. The wake-up call for the company came in 2018 when its biggest client, Apple, had lower-than-expected sales for its iPhones, and in turn, bought less AMOLED displays than agreed upon. Cupertino eventually paid a one-time penalty to Samsung Display in the millions of dollars, but it was a small solace, as AMOLED production lines eat up billions of dollars to maintain per annum. Meanwhile, the foldable display market is only just beginning. In other words, the pressure is on for Samsung Display to diversify its revenue streams.

The bigger challenge on the horizon though, is perhaps the rise of China. Samsung Display’s transition from LCD to QD-OLED for TV panels has largely been in response to the faster-than-expected rise of world’s second largest economy, whose companies have become more dominant in the LCD market. 

Display makers in China such as BOE have been developing new technology for LCD, such as dual-cell. They are also expected to invest heavily in large-sized OLED panels in a very short time frame.   

Due to losses stemming from stiff competition, Samsung Display has halted production of the LCDs at its L8-1 factory in Asan, South Korea. Two secondary lines at Asan, L8-2 and L7-2, have also reduced their LCD production rate as it places more resources into developing other technologies.
