55-inch and 65-inch models for TVs and a 34-inch version aimed at monitors
Samsung Display unveiled its quantum dot (QD) organic light emitting diode (OLED) panels for the first time at CES 2022.
The company showcased three versions of QD-OLED at a private booth __ 55-inch and 65-inch models for TVs and a 34-inch model for monitors, which has a response time of 0.1ms, according to Samsung Display.
QD-OLED uses a QD light emission layer made through inkjet printing and made with blue light emitting materials.
The blue light passes through the QD layer to express red, green and blue.
This differs from LG Display’s white (W) OLED technology that uses white light emitting materials that emit light that passes a color filter to express white, red, green and blue.
Samsung Display said QD-OLED has a high color gamut and luminance and a wide viewing angle.
The QD materials used also allow for purer red, green and blue colors, the company claimed.
Samsung Display said its panel expresses over 99% of the DCI-P3 color space and over 90% of the BT2020 color space, the widest ranging of all currently commercialized panels.
The company also said as QD-OLED is comprised of only red, green and blue pixels, this allows it to retain brightness, allowing for clearer colors.
It said adding in white pixels to increase brightness leads to the colors looking darker as the brightness of red, green and blue can’t match those of the white.
The use of QD also distributes light at a wider angle, which allows QD-OLED to retain its brightness at other viewing angles than straight from the front, the company said.
Viewing QD-OLED from the sides at a 60-degree angle retained 80% of the brightness compared to viewing the panel upfront, Samsung Display said, which is superior to that of other displays that see luminance drop to 30% to 50% at a 60-degree angle.
Samsung Display said QD-OLED offered black at under 0.0005nit and a peak brightness of 1,500nit.
