OLEDs for laptops - introduction and industry news.
OLED (Organic Light Emitting Diode) is a display technology that is brighter, more efficient, thinner and feature better refresh rates and contrast than an LCD display. OLEDs deliver the best picture quality ever and OLED displays have been used in smartphones, wearables and TVs.
Why are OLED displays better than LCDs?
- In OLED displays, each pixel emits light independently (in LCDs, there is a white backlight).
- The contrast ratio of OLEDs is much better than in LCD, so are the refresh rates and the viewing angles.
- OLEDs are thinner and lighter than LCDs, and can be made flexible, foldable, rollable and transparent.
- OLEDs are more efficient, as only lit pixels draw energy. A smart user interface can result in very power efficient OLED displays!
One of the major drawbacks of an OLED display is that because each pixel is driven independently and because the lifetime of an OLED emitter is limited, OLED panels suffer from image retention (known as burn-in). A much-used pixel is less bright than a pixel that hasn't been driven a lot (for a more technical explanation, click here). In computer user interface this is a problem - as some UI elements are quite fixed (toolbars, icons, etc). There are some technologies to handle this problem - for example by measurement and compensation, by using a tandem architecture to extend lifetime, and more. As there are millions of laptops sold annually with OLED displays, it seems as the industry has pretty much solved the burn-in problem.
OLED laptops today
OLEDs are already very successful in smartphone displays (where almost a billion panels are produced annually), OLED TVs and wearables. For some years now we are seeing an increased adoption of OLED displays in laptops, as companies such as Lenovo, Dell, HP, Samsung, Xiaomi and others adopt high-end AMOLED displays in their high-end and mid-range laptops.

Applied Materials launches a maskless OLED production technology, to support 8-Gen high efficiency OLED deposition and encapsulation
Applied Materials announced a technology, branded as MAX OLED that enables OLED display production on large glass substrates, aiming to provide a cost-effective solution to produce TV and TV displays. Applied developed and patented a new OLED pixel architecture and a "dramatically different manufacturing approach" that the company says enables brighter, clearer, more energy-efficient and longer-lasting.
Applied's new MAX OLED systems can scale from 6-Gen substrates to 8-Gen substrates, supporting the new wave of IT OLED production lines. Applied says that its new solution has strong customer interest - and already achieved repeat orders from several leading display makers (see below). Specifically, Applied announced that it will supply an R&D system to Samsung Display that will test the new production technology for its AMOLED and QD-OLED production technologies.
Samsung Display aims to increase its AMOLED production by 10% in 2025, hoping to sell more tablet displays and foldable displays
According to a report from Korea Samsung Display aims to increase its small-sized and mid-sized AMOLED panels production in 2025 by 10.25% compared to its 2024 production (or 475 million panels up from 432 million panels).
Of course SDC's production plans depend on market demand, but it seems as if the company believes the OLED market is set to grow or that the company aims to grab a larger share of the market. SDC mostly aims to increase production of IT panels (laptops and tablet displays) and foldable smartphone OLED panels.
BOE may face delays in its 8.6-Gen IT flexible OLED line, as one of its suppliers faces financial problems
Towards the end of 2023, BOE officially announced its plans for a 8.6-Gen flexible LTPO AMOLED line in Chengdu. The agreement with Chengdu's local government was signed in early 2024, and in April BOE announced it is starting to construct the new fab. A few weeks ago BOE said it finished the construction of the main outer structure in this project, and that the company is on track to finish the fab by May 2026, with mass production expected by October 2026 - and full production in 2029.
Today there is a report from Korea that one of BOE's suppliers, Hansong Neotech, faces financial problems (and its stock has been delisted from the Korean stock exchange). The company may not have enough money to coninute its operations and build the BOE systems.
Samsung is on track to start producing IT OLEDs at its 8.6-Gen A6 production line in 2026
Samsung Display is progressing as planned with its 8.6-Gen AMOLED production line. The company recently completed the installation of all major equipment in the new line, and mass production is still expected to begin in 2026.
Samsung Display is now focusing on testing, calibrating and improving all process steps, as the new fab includes new technologies that haven't been deployed before in OLED production.
Apple reportedly established four new display research labs in China, aiming to expand its OLED supply chain in China
According to industry reports, Apple recently established four display research labs in China, in Beijing, Shenzhen, Suzhou, and Shanghai.
Apple has reportedly formed an alliance with China's leading OLED makers, as the company gets ready to deploy OLED panels in its laptops and tablets. Apple is interested in diversifying its supply chain and not rely exclusively on Samsung Display and LG Display for its smartphone and IT AMOLED panels. The main goal of the new research labs is to test OLED panels produced by Chinese display makers, and evaluate and compare them to LG's and Samsung's OLEDs.
Chemtronics starts building a 8-Gen etch factory to support Samsung Display's 8-Gen IT AMOLED line
The Elec reports that Korea's Chemtronics is constructing a new fab at Sejong City that will be able to etch 8-Gen OLED substrates. This fab is built specifically for Samsung Display's new 8-Gen IT AMOLED line. The Elec said that Chemtronics already spent almost $70 million on this new fab, with Samsung supporting it with an investment as well.
The new fab will receive finished 8-Gen IT TFE rigid AMOLED panels from Samsung Display's upcoming A6 line, on a glass substrate. The new etching fab will reduce the thickness of these OLEDs from 0.5 mm to 0.2 mm, to enable lighter and thinner tablet and laptop OLEDs.
Rain Technology launches its switchable OLED display privacy solution
Rain Technology announced a new technology, called OLED Switchable Privacy, that is designed to protect OLED displays. Rain Technology says that its privacy technology already shipped in millions of LCD laptops and other displays, and is now ready for OLED displays for the first time.
OLED Switchable Privacy is embedded in the display panel smartphones, tablets or laptops, directing and controlling light from the display, thus allowing enterprises, consumers and application developers to hone unprecedented levels of automated visual security.

Visionox shares more details on its upcoming 8.6-Gen IT AMOLED line in Hefei, construction will begin towards the end of 2024
In May 2024, Visionox announced its plan to build a new AMOLED production line, targeting the IT display market - laptops, monitors and tablets. The company said that it will best 55 billion Yuan (around $7.6 billion USD) to build a 8.6-Gen production line in Hefei, Anhui province, with a monthly capacity of 32,000 substrates.
Yesterday Visionox shared some more details about its project and plans. The company will build the new fab with support from two local government-owned firms, both of which are partners at Visionox's existing 6-Gen AMOLED line in Hefei. In the first step for this new project, the three partners (Visionox and the new government firms) will invest a total of $282 million USD. Visionox will only hold 20% of the JV.
Omdia: shipments of OLEDs over 9-inch in size will soar 124% in 2024
According to Omdia, sales of OLED panels in sizes over 9-inch (the company refers to these as Large Area Displays) will increase 124.6% in 2024. In 2023, the market contracted 25.7%, with the only exception being OLED monitor panels that grew in shipments.
In 2024, Omdia says that all application areas will see an increase in shipments - TVs, monitors, tablets and laptops. Only the company's "other" category will see a decrease in sales. In particular, tablet OLED shipments are projected to increase by 294% compared to 2023, largely due to Apple's adoption of OLEDs in the 2024 iPad Pro tablets. Laptop OLED sales will increase 152.6%, and monitors OLEDs will increase 139.9%. Finally, OLED TV panel shipments will increase 34.8%.
