Large format and crisp images

Lush screens, higher image quality with “8k” and “HDR”, flexible displays to curl up – in the TV market A few years.

Who does not remember the good old tube: televisions with screen diagonals of a maximum of 32 inches, the equivalent of 82 centimeters, and stately 60 kilograms of weight? Until about 20 years ago they were found in German living rooms. Today, 32-inch models in the flat-screen version are more likely to be second-hand devices in the kitchen, in the bedroom or guest room. Larger picture formats – this is a trend in the TV sector. Televisions with 55 “or 65” screens were considered exotics until a few years ago and, due to their high price, were something for lovers and movie fans. These large-format appliances are now part of everyday life and have arrived in almost every living room. This is also confirmed by the market data from last year: In the screen class 55 to 59 inches (140 to 150 centimeters), sales rose by 7% and even by 28% in the class 60 to 60 inches (152 to 175 centimeters). Large image areas are a prerequisite for further screen trends.

More clarity and clarity for televisions

“8k” is the innovation of an ultrafine pixel grid. Devices with this technology map every image line with almost 8,000 pixels. They represent moving images with more than 33 million pixels. If you compare this resolution with the previously known “Full HD”, “8k” offers four times the amount of horizontal pixels, or 16 times the resolution. This ensures much more brilliance, clarity and sharpness in the pictures. In film studios one works already with the new technology, for consumers it must establish itself still area-wide. However, there are already TV sets with built-in scalers that can intelligently adapt material to conventional 8k screens using artificial intelligence.

“Full HD” means “Full High Definition”. Such devices map each image line with 1,080 pixels. This enables a high resolution. This becomes visible in smaller details, which do not lose their sharpness in the picture. In addition, the entire image looks better and more detailed than on devices with lower resolution.

TV trend: strong contrasts

Image quality is always the focus of further development. This also applies to moving pictures. The HDR trend, short for “High Dynamic Range”, relies on higher peak brightness values ​​for the bright effects in the images, and a deep black that is particularly noticeable on OLED screens. OLED stands for “Organic Light Emitting Diode”. Devices with this technology shine themselves and also produce the color independently. If they are black, they just stay off. This ensures that, for example, particularly dark film scenes on OLED devices actually have a deep black. These strong contrasts provide more TV enjoyment.

OLED devices also work on the basis of liquid crystals, we LCD and LED TVs. The latter, however, require a separate backlight. The reason: The liquid crystals do not light up by themselves, but rely on additional lighting. That’s why they can not display rich black in eye-catching dark scenes in a series or a movie.

Rolled out or assembled – new TV shapes

Flexible displays that roll up or how tiles can be put together without borders are also among the innovations of the TV manufacturers. At the beginning, the idea of ​​a tile originated from the limitations of another production idea. Micro-LED, also called Crystal-LED, are considered as possible screen technology of the future. The pictures consist of self-luminous crystalline light-emitting diodes. Manufacturers hope for a special longevity. If you transfer this technique to the current size of a TV, you would have to produce several small units, because large formats can not be produced in one piece. The manufacturers practically made a virtue out of necessity and developed prototypes similar to tiles, which can be combined to any shapes and sizes.

“There is still scope for spectacular developments,” explains Hans-Joachim Kaupp, Chairman of the Supervisory Board IFA-Promoter Society for the Promotion of Consumer Electronics in Germany (gfu). “This not only affects the parameters of image quality and resolution, but also new materials and designs as well as flexible and transparent displays will continue to set strong accents in the future. “
