LG Display has announced its new 4th-generation OLED TV panels, promising significant advancements in brightness and energy efficiency. The panels boast a maximum brightness of 4,000 nits, a 33% increase over previous generations, and offer a 20% improvement in energy efficiency. These enhancements are attributed to a new 'Primary RGB Tandem' structure and a revised film coating that optimizes light management.

LG Display is introducing its 4th-generation OLED TV displays today, boasting significant advancements in brightness and energy efficiency . According to the company, these new panels can achieve a maximum brightness of 4,000 nits, a 33 percent increase compared to their predecessors. While maximum brightness doesn't necessarily translate to uniform brightness across the entire display, it represents a notable improvement for OLED technology, which has often faced challenges in this area.

Adding to the appeal, LG Display claims a 20 percent improvement in energy efficiency for a 65-inch 4th-generation panel. These efficiency gains stem from enhancements to the panel's structure and power supply system. The brightness improvements, on the other hand, are attributed to a clever modification in how LG arranges the LEDs within the panel. The 4th-generation OLED utilizes a 'Primary RGB Tandem' structure, which stacks independent layers of red and green light elements with two blue layers. This layered approach allows each layer to produce more light, contributing to both increased brightness and enhanced color purity.Further refining color reproduction (and likely purity), LG Display incorporates a new film coating that minimizes light reflection from the panel's surface and reduces light absorption and reflection within the panel itself. The company emphasizes that these innovations are aimed at elevating the performance of AI TVs, but even without that context, the enhancements suggest a significant visual upgrade. The 4th-generation OLED panel is slated to appear in top-of-the-line mass-produced TVs this year. Interestingly, LG Display plans to gradually introduce the 'Primary RGB Tandem' structure into Gaming OLED monitors in the future
