LG Display could adopt a microLens array in its OLED TV panels to boost brightness and efficiency

Reports from Korea suggest that LG Display is looking into adopting a microLens array in its large OLED TV panel architecture. The microlens layer could boost brightness by up to 20%, which will also increase efficiency (if brightness is kept as before).

According to the report, the project is at an advanced stage, and panels with the microLens array could be introduced by the end of this year. LGD will apply the technology to its OLED.EX panels, so brightness could reach up to 1,200 nits. LGD considers this technology as it faces competition in large-area OLED production, from Samsung's QD-OLED panels, for the first time.

Samsung explains that LCD displays suffer from light-blurring which occurs when the outline of a bright subject appears white on an image with sharp contrast. This is because even with local dimming, LCDs cannot adjust the backlight brightness exactly on the edge. OLEDs, with their self-lit pixels, do not suffer from this.

Samsung Display starts installing equipment at its 6-Gen A4-2 AMOLED production line Asan

Reports from Korea suggest that Samsung Display is starting to install production equipment in its new 6-Gen AMOLED fab in Asan. The A4-2 line (previously called the A4-E line) is a converted old LCD fab(L7-2) that was closed in early 2021.Samsung Galaxy S22 Ultra photoIt is estimated that the A4-2 line will cost around $800 million USD. Samsung hopes to start production in the new production line by Q3 2022, and monthly capacity will be 12,500 substrates.

Samsung Display's managed to increase its QD-OLED production yield to 75%

Samsung Display recently started producing QD-OLED panels (for TV and monitor applications), and according to earlier reports, the production suffered from low yields, estimated at around 30-50% a few months ago.

In a move that is thought to reassure SDC's employees, the company announced on its internal bulletin board that it has managed to increase its QD-OLED production yields to 75%, and it now aims to increase that to 90% or higher.
