LG’s META technology on OLED TV: how does it work?

LG’s META technology improves maximum brightness and viewing angles on OLED TVs. It is integrated on certain models of 2023 LG OLED TV series. To begin LG G3, M3 and Z3, but it is possible that this solution will eventually be integrated into other models. This technology introduces a layer of microlenses (MLA for Micro Lens Array). The latter makes it possible to optimize the light by reducing internal reflections.

This new META technology brings together a set of technical solutions. The most important one is made of MLA or “Micro Lens Array” microlenses. These new tiles succeed the second generation panels OLED-EX.

LG Display has said that MLA technology will one day be applied to all of its OLED panels. For now, it’s reserved for some of its high-end offerings, including its own selection of high-end OLED televisions.

META technology recently unveiled by LG Display consists of two main components. The Micro Lens Array (MLA) layer that maximizes light emission from the OLED panel. The second component is “META Booster”, a brightness enhancement algorithm. LG Display’s press release states that these two technologies are combined in the name “META Technology”. The main improvements are:

  • Improved brightness by 60% compared to conventional OLED panels
  • Improvement of 30% viewing angles to reach 160° without image distortion
  • ONE reduced consumption (by reducing light loss)

The most notable improvement is of course the brightness. Samsung and LG are engaged in a communications battle over this figure. Samsung has announced a brightness of 2000 nits with its new generation QD-OLED panel Samsung S95C and S90C. However, this value is limited to brightness peaks over a maximum area of ​​3% of the screen. We have not yet been able to test the META technology, but the microlenses should provide a more overall increase in brightness as the overall light loss is reduced.

The new META technology is the third generation of panels from LG. She follows the technology OLED-EXsecond generation that uses deuterium and custom algorithms to improve brightness by up to 30% compared to WOLED panel first generation. These benefits are carried over to the third generation panels, but are further enhanced by META technology.

META technology, the third generation of LG OLED panels

The core of the technology is the MLA microlens layer. This new technology is used in the third generation of OLED panels. This layer of micrometer-sized convex lenses increases the light emission of the OLED panel. It also improves energy efficiency by 22% for the same brightness as previous panels. Thanks to MLA, LG Display has solved the problem of light reflection in the panel and its loss, allowing for improved brightness for the same power consumption.

The META technology and in particular the MLA microlens layer is an innovation that pushes the boundaries of OLED.

When an image is transmitted to an OLED screen, light is produced in the organic light-emitting layer. But much of this light is lost inside the panel due to internal reflection. This reduces the perceived brightness. By using a microlens system, LG minimizes the waste of light and creates a brighter screen for the same power consumption. In general, it is necessary to consume more energy to increase the brightness. However, with the Micro Lens Array structure, the efficient emission of the internal light avoids any additional energy consumption.

At CES 2023, LG showed a 77-inch 4K OLED panel with META technology. According to our discussions with LG, it has a total of 42.4 billion microlenses, or approximately 5,117 microlenses per second. pixels. This number of microlenses varies depending on panel size and pixel density. Given the number of microlenses announced, this should have a significant impact on production costs.

The META Booster technology is an algorithm from LG that enhances brightness beyond the MLA microlens layer. It increases screen brightness and improves color reproduction by analyzing and adjusting the brightness of each scene in real time.

LG Display supplies OLED displays to LG Electronic and other manufacturers. Currently, LG indicates that the META technology will be available in the following dimensions:

  • 55 inch 4K
  • 65 inch 4K
  • 77 inch 4K
  • 77 inches 8K
  • 88 inches 8K

The TVs announced with META technology are as follows:

  • LG G3
  • Panasonic 2023 MZ2000: Panasonic is the first to announce the use of META and MLA technology for its 2023 flagship TV, the MZ2000. The company advertises 150% higher brightness than their typical OLED panels. META/MLA technology will be present on their 55″ and 65″ models.

The new META/MLA technologies are not only used in televisions, but also in new OLED screens from LG Display. Currently, two panels are available in 27 inches QHD (2560 x 1440 pixels) and 45 inches (3440 x 1440 pixels), both with a refresh rate of 240 Hz. OLED displays, such as the LG 27GR95QE, Asus ROG Swift PG27AQDM , Acer Predator X27U and Dough Spectrum ES07E2D. As well as 45-inch, 3440 x 1440, 240 Hz ultra-wide OLED screens such as Corsair Xeneon Flex 45WQHD240 and LG 45GR95QE, will be equipped with this META technology. This is confirmed on LG Display’s META Technology page.
