What Is Computer Monitor & which computer monitor is best for eyes – Best Information
What Is Computer Monitor – A computer monitor is a device used to display computer-generated images. There are only two main types of computer monitors: LCD (Liquid Crystal Display) computer monitors and CRT (Cathode Ray Tube) monitors. CRT monitors have been in use for a very long time. The first CRT monitors were made in the early 80’s.
They have been in mainstream for at least 35 years and are certainly having a good day, with LCD TVs accounting for more than 50% of the 2001 market share. LCD computer monitors have been really popular only for the last 5-6 years because they are more affordable for the average user. Today, it’s not uncommon to find a good 22-inch LCD monitor for about $ 250, and it’s starting to be adopted in premium models.
The screen size of the monitor is measured diagonally. The screen size of a 19-inch CRT monitor is the same as the screen size of a 17-inch LCD computer, because the screen size of a CRT monitor is usually 1.5 to 2 inches smaller than the label size. monitor. Previously, the aspect ratio of computer monitors was always 4: 3, but after considering widescreen technology, the aspect ratio has been changed to 16: 9 or 16:10. This allows you to improve the screen space horizontally.
image. CRT monitors are usually not offered in wide screen sizes. CRT monitors may look big, so there are a few things to keep in mind when buying, mainly due to cathode ray tubes, circuits, and enclosures.
Types Of Computer Monitor
What Is Computer Monitor
A CRT monitor has a display device (CRT), a circuit that generates an image from a computer’s electronic signal, and an enclosure, but most of them are CRTs, although it may not take much time. And that’s why CRT monitors are becoming less common due to their weight and size.
CRT monitors use cathodes (hot filaments) in vacuum-sealed glass tubes to generate their screen images. The electron gun turns off the electrons at the cathode and contacts the fluorescent-coated screen that the electron beam hits.
LCD computer monitor
LCD computer monitors are significantly improved in appearance and size compared to CRT displays. The screen size of an LCD computer monitor is a much more accurate representation of the screen size. The LCD computer monitor is as thick as the circuit and the LCD screen inside the case. This means that the average thickness varies in the range of 1-2 inches. The larger it is, the larger it is. I have a 32 inch LCD TV about 3 inches thick. As I know, this extra inch makes a big difference.
LCD computer monitors are made of two pieces of polarized glass and a liquid crystal material in between. The backlight produces light that passes through the first piece of glass, while the current aligns the liquid crystal molecules while this is occurring. This allows different levels of light to pass through different pieces of glass, creating colors and images on the screen.
CRT monitor and LCD computer monitor
Pros: High contrast ratio, Fast response speed, Full range light output level, It is basically displayed , in almost all resolutions, Affordable due to the growing popularity of LCD computer monitors
Opposition: Heavy load, Heavy size and large size, High power consumption, LCD computer monitor
Pros: Determined reciprocal ratio, Response rates vary, but are much faster on high-end LCDs, Small size, lightweight, Low power consumption
Opposition: Original resolution is only one, More expensive than CRT, So which should you buy?
Use an LCD computer monitor. You will not regret it. LCD computer monitors haven’t existed for 40 years, so CRT monitors are cheaper than LCD monitors alone. This is 2021. Get a nice new LCD flat panel monitor and reward yourself. You won’t miss anything. If you already have a CRT monitor, it’s probably old and you’ll probably die. The quality will not be so good. This is a significant improvement over older CRT monitors.
