QuantumDots-Info is a knowledge hub focused on the Quantum Dots industry and markets, with a focus on quantum dots for displays.
Display market research firm DSCC says that QDEF technology (QD films for LCD displays) will continue to grow at a fast pace, rising from $236 million in 2022 to $326 million in 2025. The main market will remain TV applications. This forecast does not include any perovskite-based films.
QDEF are quantum dots enhancement films, used to enhance the color gamut of LCD displays. The main display applications for QDEF are in TVs, monitors and laptops.
Samsung Display announced that Switzerland-based evaluation services provider SGS has certified its QD-OLED panels.
The QD-OLED panels received three certifications for True Color Tones, Pure RGB Luminance and Ultrawide Viewing Angle.
Earlier this week Samsung officially launched its QD-OLED displays, with Sony, Dell and Samsung releasing the first products to use these displays.
We also have a first product review, of sorts, a short one from Tom's Guide - which says that this display is the best they have ever seen, with amazing colors and ultra-wide viewing angles.
During CES 2022, microLED developer PlayNitride demonstrated several new displays. One of these displays uses quantum dots for color conversion.
The display, 7.56-inch in size, uses two blue chips and one green, where the light of one of the blue chips is converted to red via QDs. PlayNitride says that this panel achieves a very wide color gamut and a high dynamic range.
Samsung Electronics and Dell have announced new gaming monitors that both use the same 34" curved QD-OLED panel.
Samsung has launched its Odyssey G8QNB, with a curved 34-inch QD-OLED panels that offers a resolution of 3440x1440, 175Hz refresh rate and a response time of 0.1 ms. The Dell monitor (shown above) offers the same display, which Dell promises to ship by March 2022.
Samsung Display officially launched its QD-Display panels at CES 2022, that use the company's QD-OLED technology. The company is producing three kinds of panels, 55" and 65" 4K panels for TVs and wide 34" panels for monitors
Samsung Display says that QD-OLED panels offer a superior image quality compared to LG's WOLED panels, mostly because QD-OLED is based on three RGB subpixels while WOLED is based on four WRGB subpixels. SDC says that its architecture enables higher brightness, better color fidelity and improved viewing angles.
Sony announced its 2022 TV lineup, which includes the A95K Master XR TV, which is the world's first QD-OLED TV ever announced.
The Sony A95K Master XR TV will feature 55" or 65" 4K 120Hz QD-OLED panels (produced by SDC), Sony's XR cognitive processor, Acoustic Surface Audio, XR Triluminos Max and Google TV OS. It features HDR10, HLG and Dolby Vision. Sony did not yet reveal the price or release date of its 2022 OLED TVs.
Yesterday we reported that Samsung's official CES PR did not include its upcoming QD-OLED TVs, which was a disappointment. Today it turns out that Samsung is indeed progressing with its QD OLED TV technology, as CES event organizers awarded the 65" QD-Display TV with its Best of Innovation' 2022 award.
The CES text reveals that Samsung's TVs will support 144Hz refresh rate, four HDMI 2.1 inputs and Samsung's 2022 Neo Quantum Processor. We did not see the actual TV yet, and Samsung did not reveal any launch plans yet.
According to earlier reports, Samsung Electronics was planning to officially launch its first QD-OLED TV range at CES 2022, later this week.
But reports suggest that Samsung will not do so. The company will introduce new QLED and MicroLED TVs. The reports further say that Samsung Display is still struggling with QD-OLED production and could not produce enough panels for Samsung Electronics to start selling the TVs.
A research team from POSTECH in Korea developed a new method of arranging quantum dots based on the coffee ring effect. The researchers dispersed the QD particles in a solution, and then evaporated it to perform the deposition, which causes the particles to automatically assemble in certain areas, like the edges of a single solution drop.
The researchers report that the QDs self-arranged in the form of very fine pixels, as they used a V-shaped structure. The QDs are driven toward the inner tips of the V-shape and accumulate there. This enables the creation of QD-based pixels that are 20 times brighter compared to regular QDs deposited without the V-shaped structure, and have a high uniformity rate of over 98%.
