The degradation of TV: why 3D, Curved, Plasma died out.
Almost 100 years have passed since the first TV set was introduced. In that time, the range of televisions has grown steadily, and new features and technologies have been added to the televisions themselves. We will look at some of the technologies that, despite their benefits, have become a thing of the past or are on the verge of extinction.
TVs with 3D technology
3D TVs reached the peak of their popularity in 2009 with the release of the 3D version of Avatar. However, there was not enough 3D content to justify the extra cost of 3D technology on the TV. TVs with 3D were around one third more expensive than TV models without 3D.
The popularity of the technology was also hampered by the need for special glasses for the 3D effect. It is one thing to have to put on 3D glasses just to watch a 3D film in a cinema, but quite another to wear them at home all the time. Interest in 3D started to wane in 2012 and the last 3D TV models were released in 2015-2016. 3D technology can still be found in modern video projectors.
TVs with curved screens
Curved screens are designed to enclose the screen as much as possible in the viewer's field of vision. This allows the viewer to experience more of the curved screen experience when watching movies or playing games. The trend for this type of display started in 2014. Until now, manufacturers have been offering new monitors with curved display arrays to buyers every year. Curved displays are being introduced in monitors with UltraWide and the standard 16:9 aspect ratio.
Manufacturers are experimenting by offering monitors with increasingly curved displays that are more and more enveloping to the viewer. In addition, many cinemas are also displaying hooded projection screens. However, this technology has not caught on in TV sets.
There are several reasons for the decline in popularity of curved-screen TVs. Firstly, a curved TV is more difficult to integrate into an interior. The gap between the edges of such a TV and the wall will be larger than between a conventional flat TV and the wall. Secondly, a curved screen matrix narrows the comfortable viewing angle. This is not a problem for a monitor on a table which is normally used by only 1 person at a time. However, it is not very comfortable for several people to look at a curved TV screen at different angles.
As of 2018, TV manufacturers have stopped fitting curved matrices in their most popular TV models. The last TV model with a curved screen was introduced in 2020 (Samsung TU8300 Series 8). It is likely that curved TVs will soon disappear or become a very rare, niche product. In contrast, TVs that incorporate 3D technology alongside a curved 4K display may already be considered a rarity.
The main advantage of plasma TVs is the high image contrast and deep blacks, thanks to the technology's use of no additional backlighting. Plasma technology has been abandoned in production due to the higher weight, higher cost and relatively higher energy consumption of such TVs.
Another characteristic of plasma televisions is the amount of heat generated during operation. The large diagonal size of a plasma TV could replace an electric heater. Like OLED displays, plasma displays are also characterised by pixel burn-in when the screen is static for long periods of time.
The particularities of plasma display technology make it impossible to produce displays with relatively small diagonals and high resolution. Thus, with the rise of 4K/8K resolution TVs, plasma would in any case have to be abandoned in production. The last plasma TV models were released in 2014 and were immediately followed by OLED TVs as an alternative, which have taken over many of the advantages and disadvantages of plasma.
