Samsung reported its financial results for Q3 2021, and the company states that it is on track to begin QD-OLED mass production in Q4 2021. Samsung hopes that QD-OLED TVs will start shipping to consumers in 2022.

Samsung says that its QD-OLED displays will offer many advantages over existing displays: including color reproduction, viewing angle, and brightness. Samsung is "quite confident" that QD-OLED would set the new standard, especially in the premium TV markets.

An international team of researchers from Singapore, the US and China, led by a team at Singapore-MIT alliance SMART, discovered a new way to generate long-wavelength (red, orange and yellow) emitting quantum dots by taking advantage of intrinsic defects in semiconducting materials.

The researchers fabricate InGaN QDs that feature a significantly higher indium concentration by making use of pre-existing defects in InGaN materials. In this process, the coalescence of so-called V-pits, which result from naturally-existing dislocations in the material, directly forms indium-rich quantum dots, small islands of material that emit longer-wavelength light. Simply put, the material forms itself in a structure that includes small 'pyramids' - the tops of which are actually light-emitting quantum dots.
