LG Display has begun mass production of organic light-emitting diode (OLED) monitor panels that utilize its proprietary technology, accelerating its assault on the premium monitor panel market.
LG Display announced on the 27th that it will commence mass production of the '27-inch OLED monitor panel,' which features the highest brightness (1,500 nits) among current OLED monitors, employing the 'primary RGB tandem' technology essential to its fourth-generation OLED technology. The product has a refresh rate of 280Hz, and LG Display plans to introduce a product with the highest OLED monitor refresh rate of 540Hz soon.
The primary RGB tandem technology is characterized by stacking the three primary colors of light (red, green, and blue) into four independent layers for the first time in the world. As the maximum brightness increases, the contrast ratio is maximized, allowing for a more vivid and accurate display.
The new product has also achieved a color reproduction rate of 99.5%, which is the highest level among current OLED displays. This level is suitable for professional content creation environments such as film production and color grading.
It has eliminated flicker phenomena that significantly affect the gaming experience. By improving the device structure inside the panel with a special film, it blocks 99% of light reflection both inside and outside the panel. It maintains image quality without color distortion even in a lighting environment of 500 lux, which is typical of a bright living room. It has received certifications for 'perfect black,' 'color consistency,' and '100% color fidelity' from global certification bodies such as UL Solutions and Intertek.
The response speed is at the highest level among current products at 0.03 ms. The response speed refers to the time it takes for a pixel to change from one color to another. In the case of LCD monitors, the response speed is only up to 1.0 ms. Even with a high refresh rate, a low response speed can result in ghosting from the previous frame or blurry edges.
LG Display has also succeeded in developing an OLED panel for monitors that simultaneously realizes a 540Hz high refresh rate and QHD quality. A refresh rate of 540Hz means the screen refreshes 540 times per second, providing high performance for fast-paced games such as first-person shooters (FPS) or racing games. Previously, the image quality significantly deteriorated above a refresh rate of 500Hz, but LG Display claimed it has overcome this limitation by developing and applying a new algorithm.
By applying the DFR technology developed independently by LG Display last year, it can achieve up to 720Hz at HD quality. The DFR technology allows users to select their desired refresh rate mode.
LG Display noted that it plans to commence mass production of the 540Hz OLED gaming panel in the second half of this year as major global manufacturers have completed their product launch reviews.
Lee Hyun-woo, head of LG Display's large business division, said, "OLED monitors are rapidly expanding their market share with perfect black, which is fundamentally unattainable with LCD monitors, and quick response speeds," adding, "We will enhance differentiated customer value and strengthen market dominance by leading with our 'triple crown' OLED monitors based on proprietary technology that competitors cannot follow."
