Samsung Display, the Korean conglomerate’s display manufacturing arm, showcased Eco2 OLED Plus technology at the recently-concluded K-Display 2022 expo in South Korea (via). A demonstration by the company revealed the new display technology consumes 25 percent less power than the Eco2 OLED panel employed by the Galaxy Z Fold 3. Battery consumption goes down by 35 percent when compared to a similar-sized conventional OLED panel. The Eco2 OLED technology integrates the polarizer within the panel. Polarizer helps in reflecting the outside light to improve the visibility of the screen. However, at the same time, it also blocks the light coming out from the display, thus affecting the brightness. As such, the display requires emitting more light for adequate screen brightness, which affects the battery life. Samsung’s integrated panel doesn’t require a separate polarizer. So, no light from the display is blocked. The result is a thinner display assembly that consumes less power for the same level of brightness, making the device more economical. It also reduces the use of plastic components, thus qualifying as an eco-friendly upgrade. As said earlier, the Galaxy Z Fold 4 is the first to make use of the Eco2 OLED Plus display. Going forward, Samsung may also apply this display technology to its Galaxy S series flagships. The Galaxy S23 series is an ideal candidate. We should be hearing more about it in the coming months.
The Galaxy Z Fold 4 also features Samsung’s UPC Plus technology
Samsung also showcased another display technology at K-Display 2022 expo that debuted on the Galaxy Z Fold 4. It is the company’s upgraded under-panel camera (UPC) technology that better hides the camera sensor under the screen. The Korean firm calls it UPC Plus. It features a new pixel arrangement that allows for a higher pixel density without affecting the amount of light that goes through. These upgrades enable improved picture quality while ensuring that the selfie camera doesn’t interfere with the content on the screen. The Fold series devices have two selfie cameras — a hole punch camera on the outside and a UPC sensor on the inside. People mostly use the outer one for taking selfies. This gives Samsung the liberty to experiment with the inner UPC sensor. It remains to be seen when the company will launch regular smartphones with an under-display selfie camera.
