The manufacturers of TV sets are starting the new year with a multitude of new technologies and designs for everything to do with TV cinema at home.
Micro and mini LEDs, transparent OLED screens, image processing and optimization with the help of artificial intelligence (AI) and immersive sound are just a few of the key words with regard to new technology that is making significant progress. The market demand for large screens and excellent picture and sound quality continues unabated. “Technical advances are making the latest generation of TV sets more attractive than ever. 90 years after the introduction of electronic television, the innovative strength of TV manufacturers has reached a new high. We will see a number of interesting and exciting new developments coming onto the market in 2021 “, stated Dr. Sara Warneke, managing director of gfu Consumer & Home Electronics GmbH.
Micro LED TV technology is still relatively new
Micro-LED technology is based on micrometer-sized (inorganic) light-emitting diodes (LEDs) that promise an even larger color palette and improved brightness and contrast values. The tiny diodes themselves generate the necessary light. This is why this screen technology works without color filters and backlighting.
So-called mini-LEDs are finding their way into the next generation of background lighting for LCD TVs. Up to 30,000 tiny LEDs generate the necessary light, which can be adapted to the image content with up to 2,500 dimming zones. Increases in contrast and black level as well as a large color space with high color accuracy improve the image quality as a result.
OLED technology: getting bigger and now also transparent
There are also new developments in the area of OLED technology: OLED TVs will increasingly be available in sizes over 70 inches (178 cm) in 2021. Transparent displays are now also ready for a market outside of special applications. Other models can be converted from a flat screen to a curved one at the push of a button. An interesting feature, especially when gaming. In addition, displays were presented that have low blue light emissions – an important factor in the increasing usage times of screens in general, as the blue light is suspected of suppressing the sleep hormone melatonin, among other things.
The optimization of TV images is constantly being advanced with the help of the most modern processors as well as cognitive and artificial intelligence. The result is highly detailed image content with a resolution of up to 8K. Even if the original material is not available in such a high resolution. Depending on the content and genre, the processors optimize the image and sound for each scene.
The processors also ensure that the audio signal can keep up with the growing picture: three-dimensional, so-called immersive soundscapes ensure impressive cinema sound, which together with the picture is truly overwhelming.
