LG Display has unveiled its 4th-generation OLED TV displays, which are not only designed to be brighter than previous models demonstrated in 2024, but also aim to be more energy-efficient and less reflective. The LG OLED evo M5 was highlighted as a standout announcement at CES 2025, largely due to the innovative panels produced by LG Display.
According to LG Display, the new 4th-generation OLED TV panel can achieve a maximum brightness of “up to 4,000 nits,” which represents a 33 percent increase compared to the previous generation. It is important to note that maximum brightness differs from uniform brightness across the display; however, this advancement is significant as OLED technology has traditionally faced challenges with brightness levels. This improvement is complemented by enhanced energy efficiency, which LG Display claims is around 20 percent better on a 65-inch 4th-generation panel.
The efficiency enhancements of the new OLED panels result from improvements made to the panel’s “structure and power supply system.” Meanwhile, the brightness enhancements stem from a clever adjustment in the arrangement of LEDs within the panel. The 4th-generation OLED employs a “Primary RGB Tandem structure,” which stacks independent layers of red and green light elements alongside two blue layers. This layering allows for increased light production, enhancing both brightness and color purity.
In addition to brightness, LG Display is improving color reproduction with a new film coating that minimizes the amount of light reflected from the surface of the panel, as well as reducing light absorption and reflection within the panel itself. The company asserts that these advancements are aimed at creating superior “AI TVs.” However, even if AI features are not enticing, it appears that televisions featuring these new panels will indeed offer better visual quality.
The 4th-generation OLED panels are expected to debut in “top-of-the-line mass-produced” televisions this year. Furthermore, LG Display has stated that the “Primary RGB Tandem structure” will gradually be incorporated into Gaming OLED monitors in the future.
