LG has unveiled the next generation of its OLED technology, which it says is brighter and more energy efficient than ever.

It’s been a little more than a week since LG’s 2025 OLED TV lineup was revealed at CES 2025. During the showcase, LG dropped quite a big bombshell: Its top two OLED TVs, the G and M Series, would no longer be leveraging Micro Lens Array (MLA) display technology to enhance panel brightness.

LG Display's new 4th-generation OLED panels are 33 percent brighter than previous generations, while also being more power-efficient.

LG Display Co. on Thursday unveiled its new fourth-generation organic light-emitting diode (OLED) panel designed for artificial intelligence (AI) TVs as part of its push to lead the premium screen market.
