Televisions with cathode ray tube technology until the late 1990s and early 2000s They have accompanied us for most of our lives.. In fact, even today it is possible to have this type of television in your storage room, which is currently highly desired, especially by lovers of retro video games.
But before technology slowly disappeared from homes, CRT TVs also stepped into high resolution. Before plasma and LCD televisions were superseded, there were manufacturers who released several models with HD resolution, a significant evolution and a logical step in a context where the digital age was increasingly taking shape.
What are CRT TVs?
Colloquially known as ‘tube televisions’ or ‘CRT televisions’, this technology is the technology for which the television was designed, that is, through a cathode ray tube that falls on an electroluminescent glass screen covered with materials such as phosphor and lead and creates an image. from a large voltage difference. The lead was used to block the X-rays from the process that were harmful to the wearer, while the phosphor allowed the image to diffuse.
Characterized by their bulky dimensions and 4:3 aspect ratio convex screen, these televisions have spent most of our time in our living rooms, often being replaced by more efficient, higher-definition and less bulky (or at least flatter) televisions. as we can currently see televisions over 100 inches). In addition, these televisions can pose a risk to the user due to the toxicity of the materials they use and the voltage required to operate them.
CRT TVs with HD resolution
They began to appear in the late 90s and early 2000s. These can offer 720p or even 1080p resolution, thus offering a 16:9 aspect ratio and a flat panel (as opposed to the characteristic curve of CRT TVs). They had a similar size in terms of dimensions and also made use of CRT technology to create the image, which is why such televisions are large in size.
At that time, its use was very common in television channels and stations that developed HD content. However, this content did not begin to arrive until HD resolution was established in the market.
When high definition started to settle in homes, we were able to find CRT HD television models in the market. Some manufacturers using this technology were Sony, Samsung, Philips, Panasonic and others. Again, These TVs weren’t cheapbecause the supply and production of the raw material required for its development was more difficult than the one used in plasma and LCD televisions, which have just begun to enter the market.
The picture quality offered by these televisions Much better than previous CRTs. Its marketing went beyond televisions to include computer monitors.
High resolution came in an instant there was a need to improve the hardware on the televisions. For this reason, CRT TVs with HD resolution did not last long in the market. Also, plasma and LCD televisions were just around the corner and started to become cheaper and more accessible to the user.
Although they are almost obsolete at the moment, there is a niche that continues to take advantage of them today, because It is a highly recommended option for playing old or low resolution content.. Retro video game lovers often recommend this type of TV for playing 8, 16 or 32 bit game consoles.
