Great news for cheap OLED TVs and monitors: LG's new '2-stack' tech should cost less to make and be more energy efficient than its recent 'OLED SE' panel
LG's new 2-stack OLED panel is cheaper to make and delivers better color and viewing angles than current WOLED panels, the firm says
LG has unveiled a new "2-stack" OLED panel that promises to be both cheaper to produce and more energy efficient than its previous "OLED SE" panel. This new panel features a redesigned emissive layer, with a blue emissive material replacing the conventional yellow/green layer and separate red and green layers. This change is said to enhance color reproduction, boosting BT.2020 color coverage from 76.5% to 82.5%.
The new panel is also slightly brighter at 6500 Kelvin color temperatures and offers wider viewing angles. While the new 2-stack technology has been used by LG Display in the past, the more stacks provide improved picture quality and brightness, making the 2-stack design a breakthrough. The new panel is expected to be used in mid-range OLED TVs and computer monitors, potentially competing with mini-LED technology.
However, it is not yet available in mass production, with LG Display not yet providing a timeline for its wider adoption. For now, entry-level OLEDs like the Panasonic Z86C continue to use the OLED SE panel, which offers brighter but potentially more reflective displays.
