Earlier this week Samsung confirmed that they have acquired QD Vision, the US-based provider of quantum dot technology for consumer displays. According to sources cited by SamMobile, the deal was confirmed ahead of its official announcement next week by Jung Chil-hee, the head of Samsung's Advanced Institute of Technology.

No details about the price of the acquisition are available yet, but from an observer's point of view it makes sense that Samsung would want to acquire companies working in the field of quantum dots. Samsung has been heavily pushing quantum dots in their newest televisions in order to increase their color gamut without having to make use of backlights with multi-color LEDs. With Ultra HD content being mastered in the DCI-P3 or Rec. 2020 color spaces, this has become a necessary feature in high end televisions and monitors for content creation.

QD Vision's technology works in a different manner from the technology Samsung currently uses in their televisions. In order to support HDR, televisions need to use full array backlighting so regions can be dimmed locally, and employing quantum dots in this situation requires a film layer between the backlight and the LCD array, which can be quite costly for larger displays. QD Vision's technology works with edge-lit displays and places tubes of quantum dots between the LEDs and the guide plate that distributes light across the display. I took a look at a monitor that uses QD Vision's technology earlier this year. It's not clear where Samsung plans to utilize QD Vision's technology, but the technology could play a big role in bringing wide color gamuts to lower cost displays, and QD Vision's technology and patents related to quantum dots would also have value to Samsung for further development of the technology in general.

    Why do you need backlight when you got OLED? LCD was and always will be a primitive technology that only exists because it was cheapo to sell compared to plasma killing in the process the true successor of CRT's:

    It's a shame that sed didn't work out, although it's unclear if it could ever have been made cheap even compared to OLED.

    OLED still has lifespan issues, and the cost is more than most people seem willing to pay. LCD will still be around for a long time.

    LCD + Quantum Dots = widest colour gamut, cheapest price, not toxic materials. Reply

    Panasonic used red and green phosphors in their backlight to achieve a wider color gamut, but the appear to be leaving the TV business. They have already pulled out of the US. Reply

    Cool post. I recently purchased Galaxy S8 on Ebay that was bought in Italy.
    I live in Germany and here Samsung Pay didn't work on this phone. Flashing the phone helped to solve this problem. I downloaded firmware here https://sfirmware.com
