You’re right about that, but it’s only fair to make a comparison in the age of technology.

CRT has been a long time coming to final status, and the technology has always remained the same. The first CRT invention dates back to 1897.
Although, of course, this was not comparable to the black and white televisions that went into mass production in the 50s of the last century.

The color inline picture tube has remained virtually unchanged since then. It entered mass production in 1972 and remained the underlying technology until the end of the CRT era.

In the beginning CRT monitors wore out terribly because they had not yet got their phosphor wear under control. This problem has been worked out over the years, but it really took its time.

You now also see the same problem with flat screen monitors that use various technological capabilities.
The CRT suffered from burn-in, which was later largely resolved when it was replaced with an LED, which still had defects such as lighting.
This has now been partially solved with minified, but we’ll have to wait until true microscreens are available, where each pixel has its own light source.

In the meantime, we also had the Plasma, of which OLED is actually the technical successor (though with different technologies. But both fast response times and true black)

OLED is a technology that I personally appreciate the most at the moment, although I have to admit that some of the smaller LED screens are very pretty in terms of picture.

If Nanoled gets hacked soon, I’ll be able to switch to it personally. But there too I wait until it gets in the way and the first few generations develop teething issues.

In short, if flat screens also have 30-50 years of development behind them, they will have to see what the technology does in terms of lifespan.
