Hi, this is Wayne again with a topic “Why Tube TVs DIED”.
There are plenty of old pieces of technology that we can wax nostalgic about, but perhaps none used to be more common in our homes than the good old CRT television. You know those heavy boxy consoles that made interesting noises when you flip them on or off, and it wasn’t just TVs. Crt computer monitors were also ubiquitous for a long time, but then starting in the early to mid-2000s, they began to disappear and then seem to be gone in the blink of an eye just a few short years later. So why did they vanish from our lives and how did it happen so fast well to understand this? It first helps to understand how a CRT works at the back of a CRT display is an electron gun that fires electrons at the front of the set, the inside of which is coated in phosphorous that glow different colors when they’re hit CRTs also have steering coils At the back, which aim the electrons to different parts of the screen by adjusting their own voltages, the technology itself is fairly simple. But the issue is that this entire apparatus needs to be contained in some pretty heavy-duty glass in order to work properly. So both the tube itself, as well as the front phosphor coated glass that makes up the screen. This glass adds considerable weight and bulk to any CRT display and because the tube needed to be a certain length in order to fire and aim the electrons properly.
It also limited the size of the screen, as a super-deep tube would have been required to go any bigger. So, for a long time, all this bulk was the scourge of moving days around the world until the flat panel display came along now, although flat panels were very expensive and with inferior image quality, when they first started, hitting the market, manufacturers quickly got better at churning Them out efficiently, one big reason for this is improvements in the way that LCD displays have their circuits printed on to them. Although these printers used to have very limited capacities today, there massive making it much easier for manufacturers to ship out huge numbers of flat panel displays quickly. This and other improvements in technology quickly made LCD displays competitive and price and even display quality with CRTs. So no one really saw a reason to keep buying bulky heavy power-hungry units instead of lighter more power, efficient ones. Plus there was the fact that LCD screens could eventually be made much larger than CRTs, since they didn’t need quite so much junk in the trunk.
So, while demand for flat screens spiked the market share of CRTs plummeted, in fact, one UK retailer reported back in 2004 over 80 % of the TVs they sold were CRTs, but then that in 2006, that number had dropped to less than 5 %. Today, there aren’t even any companies remaining that actively manufacture, CRT displays, but while the technology is largely obsolete, that doesn’t mean that it’s useless. For example, have you ever tried to hook an older game console like your Nintendo 64 up to a modern flat panel display? Well, despite the fact that LCD and OLED TVs are superior in many ways, you might have noticed that your classic games don’t look nearly the way that you remember them. Looking on your old CRT, this is due to a couple of technical reasons.
Old-School consoles were actually designed to work with TVs that could better handle interlaced video signals. That is TVs. That would only draw every other line of an image on each pass, and that was of course, common in CRTs modern flat panels. Instead, draw the entire image at once, so that combined with the fact that old CRTs could change resolutions without sacrificing image clarity.
The way that LCDs do met that they could much better accommodate the lower and sometimes oddball resolutions of old consoles. Even the fanciest of new flat panel displays often produce funky looking artifacts. If you try to play retro games on them without investing in an expensive outboard. Scaler so it turns out, then there’s still quite a secondhand trade in CRTs, among classic game aficionados, as well as AV junkies, who appreciate the deep blacks, negligible input, leg and the smooth motion that CRT is provide.
