[CES 2024] LGD Unveils Large OLED Panel with 42% Brightness Improvement for the First Time

'Meta Technology 2.0' Development and Application
Case of Technology Upgrade After 1 Year
Enhanced Completeness with Proprietary Algorithm
First Applied to Large and Extra-Large OLED TV Panels

LG Display introduced a new OLED TV panel featuring its new technology, 'Meta Technology 2.0,' on the 8th (local time), a day before the opening of 'CES 2024,' the world's largest electronics and IT exhibition held in Las Vegas, USA. The company also detailed plans to strengthen its dominance in the OLED market by prioritizing the application of Meta Technology 2.0 to its large and extra-large OLED TV panel product lineup scheduled for mass production this year.

Meta Technology 2.0 is a technology that enhances luminance (screen brightness), a key factor in image quality. For the new OLED TV panel products, this technology supports a maximum luminance of 3000 nits (one nit equals the brightness of a single candle). Among large OLED panels, this is the first time luminance has been increased by about 42% compared to the previously brightest products. LG Display attracted visitors' attention by unveiling an 83-inch OLED TV panel applying Meta Technology 2.0 for the first time on this day.

Technology upgrade in just one year... includes proprietary algorithms

Since the first mass production of OLED TV panels in 2013, LG Display has been conceptualizing high luminance technology and, after about 10 years of research and development, developed Meta Technology 2.0, which surpasses the limits of OLED image quality. Following the introduction of Meta Technology 1.0 last year, this is a case of showcasing an evolved technology within just one year.

Meta Technology 2.0 combines ▲an optimized micrometer-scale lens pattern 'MLA+' ▲a multidimensionally evolved luminance optimization algorithm 'Meta Multi Booster' ▲a full grayscale (difference between bright and dark areas) image enhancement algorithm 'Detail Enhancer' to amplify maximum luminance up to 3000 nits.

MLA is a technology that maximizes light extraction and increases luminance through tiny, invisible micrometer-scale convex lens patterns. Since it requires uniformly producing tens of billions of ultra-fine lenses, the technology is highly challenging. LG Display introduced MLA+, which optimizes the angles of the micro lens patterns to emit even the small amount of light lost due to internal panel reflection outside the screen. MLA+ is similar in function to an insect's eye and is also called the 'dragonfly eye technology.'

Meta Multi Booster is an algorithm that analyzes images in multiple dimensions to finely optimize image quality by enhancing not only the maximum luminance, a strength of LG Display's OLED panels, but also color luminance. Meta Technology 2.0 achieves a color luminance of 1500 nits, a 114% improvement compared to previous levels, through the combination of MLA+ and Meta Multi Booster. Higher color luminance allows for better HDR effects, making bright areas brighter and dark areas darker.

Another algorithm, the Detail Enhancer, enables consistent and accurate color representation in both bright and dark images. Generally, displays have difficulty accurately rendering image quality in dark scenes (low grayscale) compared to bright scenes (high grayscale). To improve this, LG Display independently developed the Detail Enhancer. The development was enhanced by adding new data processing technology to the OLED 'pixel dimming' technology, which finely controls light.

Going forward, as demand for extra-large TVs continues to grow, LG Display plans to prioritize the application of Meta Technology 2.0 to its large and extra-large OLED TV panel product lineup scheduled for mass production this year, strengthening OLED's leadership in the premium TV market. The lineup includes 4K 55-, 65-, 77-, and 83-inch models, as well as 8K 77- and 88-inch models.

The company expressed its ambition to further strengthen OLED's leadership in the global premium TV market through this technology. Lee Hyun-woo, Executive Vice President and Head of LG Display's Large Business Unit, said, "Meta Technology 2.0 is the pinnacle of display technology that transcends constraints and limitations to achieve perfect harmony with humans, nature, and the environment." He added, "With the evolved Meta Technology 2.0, we will firmly establish a technological gap in the OLED TV panel market."

OLED is a display technology where each pixel emits light on its own without a separate backlight. It boasts infinite contrast ratio and accurate, rich color expression. OLED TV panels equipped with Meta Technology maximize light emission, resulting in approximately 22% higher energy efficiency compared to previous models at the same luminance level. Additionally, they emit less harmful blue light and have no flicker (screen blinking phenomenon).
