LG's new 4th-gen OLED TV panel can hit 4,000 nits peak brightness

LG has officially detailed its 4th-gen OLED panel that will be featured in the company’s 2025 flagship TV lineup. The latest OLED panel boasts a number of improvements over its predecessor, including a significant boost in brightness, improved energy efficiency, and a glare-free viewing experience.

First things first. LG has done away with the Micro Lens Array (MLA) layer in favor of a new Primary RGB Tandem structure. This new structure uses four stacks to organize the light source and is made up of two layers of blue elements and independent layers of red and green elements. This is an improvement over the 3rd Gen panel, which arranged the red and green elements in a single yellow layer. LG says this new approach allows the panel to achieve a peak brightness as high as 4,000 nits on a 3% window in Vivid mode, a 33% increase over the previous generation (3,000 nits). The maximum color brightness also sees a whopping 40% improvement, with the new panel capable of reaching 2,100 nits. In fullscreen (100% APL), the panel can deliver 400 nits of brightness, a step up from 250 nits on the 3rd-gen. At the same time, LG says it was able to reduce power consumption by 20%, thanks to the 4-stack structure, improvements in diodes, and power supply system.

OLED panels are known for delivering deep blacks and punchy colors, but they’re also prone to light reflections due to their glossy nature. To address this, LG has applied a new anti-reflective film that can block 99% of internal and external light reflections for a glare-free viewing experience. In addition, we're told that the panel sees no loss in its color gamut and accuracy even in bright environments (500 lux). As LG Display explains:

With the advantage of this ultra-low reflection technology, the company’s fourth-generation OLED TV panel blocks 99% of internal and external light reflections, realizing perfect black just like in a movie theater with the lights off even in a midday living room setting (500 lux)

LG’s 4th-gen OLED panel will be made available in 48, 55, 65, 77, and 83-inch screen sizes. Among the first TVs to feature the new panel include the LG G5 series, LG M5 series, and Panasonic Z95B lineup. Beyond TVs, LG also plans to expand its Primary RGB Tandem tech to its Gaming OLED monitor lineup.
