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

LG’s META technology improves peak brightness and viewing angles on OLED TVs. It is built into certain models of the 2023 LG OLED TV range. To start the 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 micro lenses (MLA for Micro Lens Array). The latter allows to optimize the light by reducing internal reflections.

This new META technology brings together a number of technical solutions. The most important is the layer of MLA or “Micro Lens Array” microlenses. These new tiles follow the second generation panels OLED EX.

LG Display has announced 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 Range of high-end OLED TVs.

META technology was recently introduced by LGDisplay 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 come together in the name “META Technology”. The main improvements are:

  • Improved brightness by 60% compared to conventional OLED panels
  • improvement of 30% viewing angle to achieve 160° without image distortion
  • A reduced consumption (by reducing light loss)

The most noticeable improvement is of course that of the brightness. Samsung and LG are in a communication dispute over this number. Samsung has announced a brightness of 2000 nits with its new generation of QD OLED panels Samsung S95C and S90C. However, this value is limited to brightness peaks over a maximum area of ​​3% of the screen. We haven’t been able to test the META technology yet, but the microlenses should offer a greater overall brightness boost due to the overall reduction in light leakage.

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

META technology, the third generation of LG OLED panels

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

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

When an image is transferred to an OLED screen, light is generated in the organic light-emitting layer. However, much of this light is lost due to internal reflection within the panel. This reduces the perceived brightness. By using a micro-lens array, LG minimizes wasted light and creates a brighter screen with the same power consumption. In general, to increase the brightness, it is necessary to consume more energy. However, with the micro-lens array structure, the efficient emission of the internal light avoids any additional power consumption.

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

META Booster technology is LG’s algorithm that improves luminosity in addition to 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. At the moment LG states that the META technology will be available in the following dimensions:

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

The announced TVs with META technology are as follows:

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

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