why lcd is better than crt?

More adjustable - LCD displays are much more adjustable than CRT displays. ... Less eye strain - Because LCD displays turn each pixel off individually, they do not produce a flicker like CRT displays do. In addition, LCD displays do a better job of displaying text compared with CRT displays.

CRTs can damage your eyes. They are shooting electrons directly at them. Part of the reason why I will never go back to using a CRT.

CRTs are technically not displaying full 1080i, but they can accept a input signal of that resolution. It certainly looks better than SDTV, as previously mentioned. In the past year, I've bought approximately 12 new screens, monitors and TVs combined.

Although much less susceptible than Plasma TVs, LCD TVs are still subject to screen burn in (image retention). ... If you are using your LCD TV as a computer monitor, the same general rule holds true: Avoid keeping a static picture or a picture with static elements (black bars, black borders, logos, etc.)

Both plasma and OLED displays offer excellent blacks since they can completely turn off individual pixels, but OLED does it better. The way plasma panels are constructed causes a small amount of ambient light to be refracted out to the viewer, and OLED displays don't have this problem.

“2ms” is exactly the amount of input lag we expect for an LCD over a CRT. ... High-refresh-rate monitors have lower input lag because they draw frames faster. A 120Hz CRT would have 4.2ms of input lag. A 144Hz CRT would have 3.5ms of input lag.

OLED vs LED LCD – How are they different? In a nutshell, LED LCD screens use a backlight to illuminate their pixels, while OLED's pixels actually produce their own light. You might hear OLED's pixels called 'emissive', while LCD tech is 'transmissive'.

LCDs tend to have a higher native resolution than plasmas of similar size, which means more pixels on the screen. LCDs also tend to consume less power than plasma screens, with some of the newer "Eco" LCD panels able to use half of the power than equivalent plasmas, with the trade-off being lower brightness.

The advantages of CRT technology over modern flat panels are well-documented. CRTs do not operate from a fixed pixel grid in the way an LCD does - instead three 'guns' beam light directly onto the tube. So there's no upscaling blur and no need to run at any specific native resolution as such.

Monitors usually have lower input lag, higher refresh rates, and a faster response time than TVs which make them a better choice for gaming. On the other side, TVs are larger and more affordable so they are awesome for watching movies and TV shows as well as console gaming.

LCD monitors use a very different method for producing the image on the screen and are supposed to be immune to this burn-in effect. ... While LCDs are not susceptible to the burn-in the same way CRT monitors are, they do suffer from what the manufacturers like to call image persistence.

In theory, 120Hz is definitely better; as the screen is refreshed twice as often, motion should look better. Unfortunately, though, there is very little 120Hz content available. Most mid to high-end TVs these days have 120Hz screens, whereas most budget models have 60Hz screens.

The issue with CRTs is that they degrade with use. Commercial grade new CRTs still sell today new for the same price they did 5-6 years ago, if you can even find one. But a used one that's 10-15 years old is very likely not worth anything unless it sat in a box for most of those years.

QLED is brighter. In my tests, however, OLED TVs can still get plenty bright for most rooms, and their superior contrast still allows them to deliver a better overall HDR image than any QLED/LCD TV I've tested.

OLED is the winner here because it can get extremely bright, plus it can produce absolute black with no blooming. It has the best contrast ratio of any modern display. Contrast ratio is the most important aspect of picture quality.

CRT TVs were also bulky because the electron guns that fire electrons at the inside of the screen need a certain angle of attack to work properly. With a large screen, the guns need to be farther away to achieve this angle with respect to the outer screen edges.

While LCD technology uses tiny light-emitting diodes behind liquid crystal displays for designs that are remarkably thin and energy-efficient, OLED televisions offer stunning ultra-thin silhouettes and remarkable standby energy consumption due to OLED's ability to completely switch off black pixels.
