Recently, it was reported that Samsung Display will stop the existing LCD panel production line in August this year, convert it to a QD-OLED production line, and achieve the goal of mass production of QD-OLED in 2021. The outflow of this news has attracted countless discussions and detonated the panel industry. So what is the difference between QD-OLED screen and OLED screen? Which screen is better?

With the concentrated mass production of ultra-high-generation panel production lines in the past two years, the panel production capacity in mainland China has continued to increase, and the oversupply of LCD TV panels has entered the most severe stage in history. The long-term fluctuation pattern of panel prices has been broken. In just six months, after two sharp drops, the prices of mainstream products have completely fallen below the cash cost line. All LCD TV panel businesses have entered a period of total loss, and it is difficult to restore normal operations in the short term. level. Therefore, through the transformation of production lines, Samsung gradually reduced the drag on the company’s profits from LCD TV panels, and accelerated its investment in high value-added new technologies – QD-OLED technology.

What is QD-OLED? Samsung details its new TV display tech

According to Samsung Display, QD-OLED will have “brighter and wider color performance”, deep blacks, fast response and wide viewing angles. It also reduces visual discomfort.

What is QD-OLED? Display panel maker Samsung Display has released a website introducing its new QD-OLED display technology, and Samsung Electronics is rumored to launch 55- and 65-inch QD-OLED TVs next year.

The company explained that the “blue self-emissive” layer (which can be OLED or microLED) produces blue light, the intensity of which can be adjusted at the pixel level. In both subpixels, blue light is converted to red and green (for RGB pixels) by using quantum dot color converters instead of the color filters currently found in displays such as LCDs and LG’s WOLEDs. Samsung Display compares QD-OLED to LCDs – such as current Samsung “Neo QLED” or “QLED” LCD TVs – highlighting the advantages of self-illuminating display technology.

– “Traditional displays limit screen brightness because of light source or power consumption issues. With a backlight unit as the light source, LCDs are nearly impossible to control the brightness of each individual pixel, limiting their ability to show you perfect blacks on the screen. Unlike LCDs, the blue light source of a QD display can control the light source of each individual pixel. Samsung Display said: “A QD display with 4K resolution has approximately 8.3 million (3840 × 2160) light sources that can be individually controlled.

The commercialization of the Mini-LED industry is accelerating and industrial chain manufacturers are expected to leverage

For Samsung, the QD-OLED that it has invested heavily in research and development (announced in October last year, invested 10.85 billion US dollars in research and development, or about 73.5 billion yuan), will be left out by themselves.

According to South Korean media reports, Samsung Display, a screen-focused company under Samsung Electronics, has invested a lot of money in the research and development and production of QD-OLED screens, but now facing the dilemma that Samsung Electronics may not be used for TVs, they have already Start looking for other buyers.

The report also mentioned that Samsung Display is currently facing a problem they did not expect. Samsung Electronics is hesitating whether to adopt QD-OLED screens, which may not be shipped next year, or may not be adopted at all. In terms of next-generation screens, Samsung Electronics wants to focus on microLED, because they found that TVs using QD-OLED screens did not meet their expectations in terms of brightness, and there were screen burn-in problems.

According to Korean media Business Korea, Samsung Display will supply TCL with QD-OLED TV panels next year, and TCL has decided to order QD-OLED screens from Samsung Display, which plans to launch at the Berlin International Consumer Electronics Show next year. Their first QD-OLED TV, while Samsung Display will also supply QD-OLED screens to Sony and Panasonic.

According to industry chain sources, Samsung Display Corporation (SDC) will mass-produce QD OLEDs in the fourth quarter, and QD OLED TVs will be released at CES 2022.

A few days ago, SDC decided to produce QD OLED panels on the 8.5th generation production line Q1 in Asan, Chungnam in November, with a monthly production capacity of 30K mother glass. Since the middle of this year, Samsung has successively conducted trial production, testing and evaluation of samples. Sony, Panasonic and well-known Chinese TV manufacturers are potential partners.

SDC plans to have 55 inches and 65 inches as the primary sizes for mass production first. A 70-inch model will follow at a later date.

The SDC 8.5 generation line uses the MMG sleeve cutting process. There are many ways to combine the size of SDC Gen 8.5 line, which can produce 3 sheets of 65 inches and 2 sheets of 55 inches at the same time; 3 sheets of 65 inches and 6 sheets of 32 inches are also the most common nesting combinations in Gen 8.5. RUNTO forecasts that the annual shipment of QD OLED TV panels will be 1.4 million units in 2022, taking into account yield.

In the most cutting-edge display technology, OLED TVs are showing new vitality in the qualifying competition of various display technologies.

Especially in the first half of this year, under the multiple stimulations such as the rich and diversified panel supply and the price drop, many color TV brands are currently more enthusiastic about the participation of OLED TVs. Not only is the number of new OLED TV products increasing, but product competitiveness is further strengthened, while market promotion efforts are expanding. From the overall trend, the OLED TV market has ushered in accelerated growth, and the overall sales volume is entering a new new node.

According to statistics from Sigmaintell, the global OLED TV shipments in 2021 will be 6.3 million units, a year-on-year increase of 77%. By 2022, the shipments will be close to 10 million units, a year-on-year increase of 51%. 4%.

In the face of the current situation of OLED TVs, Samsung, the world’s No. 1 color TV brand, can’t stand its “moving heart”.

At the beginning of the year, it was rumored that Samsung would “intentionally” purchase large-size OLED TV panels from its “rival” LGD, preparing to release OLED TVs in mass production this year. But after that, the news was “clarified” by both parties. The two parties just approached briefly and did not sign a substantive purchase agreement.
