Sony launches the world’s first QD-OLED 4K TV

Sony TVs use QD-OLED panels manufactured by Samsung, which are said to have better brightness and colors than OLED screens.

Earlier, some sources said that Samsung will introduce the first QD-OLED TV at CES 2022 , taking place from today in Las Vegas. However, Sony surpassed the Korean electronics company when it launched the high-end Bravia XR A95K model. This model uses a QD-OLED (quantum dot OLED) quantum dot panel with two sizes of 55 inches and 65 inches with 4K resolution.

The new TV has a unique design with integrated cable management system, increasing aesthetics. The stand allows the device to be positioned in many different positions. The product has four HDMI ports, supports 4K 120 Hz gaming, HDR when connected to PS5.

Sony uses the Google TV operating system for the 2022 TV series with exclusive technologies such as XR OLED Contrast Pro, XR Triluminos Max Acoustic Surface Audio Plus. The company said it will still launch TVs using OLED screens from LG Display on lower-end models, Bravia A90K and A80K.

QD-OLED panels have been developed by Samsung Display for many years with the goal of transitioning between standard OLED displays and MicroLED that only Samsung is currently trading. QD-OLED combines the advantages of OLED such as deep blacks, infinite contrast… with the advantages of quantum dot LED, such as more vivid color reproduction at higher brightness levels.

Also, the difference between Samsung QD-OLED and LG OLED is the way the image is created. LG displays are considered WRGB OLEDs because they use blue and yellow diodes to create white light pixels that pass through color filters, thereby producing red, green and blue sub-pixels. Recent OLED TV models add white sub-pixels to enhance brightness, especially for HDR content.

Meanwhile, with QD-OLED, the screen emits blue light through the quantum dot to convert to red and green without color filter, thus making the use of light energy more efficient. This helps the QD-OLED TV to have a higher brightness than the previous generation OLED. QD-OLED is also able to maintain vivid color reproduction even at the highest brightness levels, while WRGB OLED can sometimes exhibit some saturation at maximum brightness.

On newly launched TVs, Sony says QD-OLED increases brightness and color by up to 200% compared to conventional TVs. The viewing angle that is the strong point of OLED is said to be even better on QD-OLED.

QD-OLED screens still won’t eliminate the possibility of burn in, but TVs using this panel will likely have a longer lifespan than current OLED TVs because the pixels aren’t as active. Samsung Display is using three layers of blue OLED material for each pixel, helping to preserve their lifespan.
