LG Display announced today that it has successfully begun mass production of the world’s top OLED monitor panel, incorporating its latest proprietary technology as the company accelerates its push into the premium monitor panel market. The 27-inch OLED monitor panel achieves a peak brightness of 1,500 nits thanks to the application of the company’s core fourth-generation OLED technology, Primary RGB Tandem.

In addition, LG Display has successfully developed a 540Hz OLED monitor panel - surpassing the highest refresh rate currently available - and plans to unveil it soon.

As a result, LG Display is leading the world’s OLED technology across the “triple crown” of key elements that determine gaming monitor picture quality - brightness, refresh rate, and response time.

By incorporating its proprietary Primary RGB Tandem technology, LG Display’s 27-inch OLED monitor panel delivers the highest peak brightness among existing OLED monitors - 1,500 nits (based on APL 1.5%) and a refresh rate of 280Hz. This technology is the world’s first to stack the three primary colors of light - red, green, and blue - into four separate, independent layers. By increasing peak brightness, it maximizes contrast ratio, delivering more vivid and accurate visuals.

The panel also achieves a color reproduction rate of 99.5%, the highest among existing OLEDs and a level that is suitable for professional content creation environments such as film production and color grading.

Moreover, it eliminates screen glare, which significantly impacts the gaming experience, blocking 99% of internal and external light reflections through a special film and improved internal panel element structure. As a result, it maintains perfect picture quality without color distortion even under lighting conditions of 500 lux - the brightness of a living room in broad daylight. This has enabled the panel to obtain certifications for Perfect Black, Perfect Color, and 100% Color Fidelity from global organizations such as UL Solutions and Intertek.

LG Display additionally revealed details of its development of the first OLED monitor panel to simultaneously support a 540Hz refresh rate and QHD resolution. A 540Hz refresh rate means the screen refreshes 540 times per second, delivering overwhelming performance in fast-paced games such as first-person shooters (FPS) and racing titles.

Exceeding a 500Hz refresh rate had been considered a virtually unbreakable threshold due to the associated steep drop in picture quality. LG Display has successfully overcome this limitation by developing and applying a new proprietary algorithm. The 540Hz refresh rate goes beyond even the highest standards envisioned by professional gamers for OLED gaming monitors.

Meanwhile, LG Display’s proprietary Dynamic Frequency & Resolution (DFR) technology enables ultra-high refresh rate modes of up to 720Hz in HD resolution. DFR allows users to select their preferred refresh rate mode depending on the content.

The company’s OLED monitor panels also feature an industry-leading response time of 0.03ms, far surpassing the performance of LCD monitors, which have a response time of up to 1.0ms.

Response time refers to how long it takes for a pixel to change from one color to another. Even with a high refresh rate, if the response time is slow, blurred edges or ghosting from previous frames can occur. A fast response time is essential to fully experience the speed of fast-paced games.

LG Display’s OLED panel for monitors combines an ultra-fast 0.03ms response time with a high refresh rate of 540Hz, meeting the highest tier of the relevant Video Electronics Standards Association (VESA) standard - ClearMR (Clear Motion Ratio) 21,000. A higher ClearMR value indicates better picture quality, greater clarity, and reduced motion blur.

With major global set manufacturers having completed launch evaluations, LG Display plans to begin mass production of its 540Hz Gaming OLED panel in the second half of this year.

“OLED monitors are rapidly expanding their market share thanks to perfect black levels and fast response times - capabilities fundamentally unattainable by LCD monitors,” said Hyeon-woo Lee, Head of the Large Display Business Unit at LG Display. “With proprietary technologies like fourth-generation OLED and DFR, which competitors cannot replicate, LG Display will enhance its competitiveness in the premium monitor market and deliver differentiated value to customers.”
