Difference between CRT, LCD and LED monitors
Technology is evolving at an exponential pace while the outstanding gadgets of the past are becoming obsolete and the new technology is rapidly replacing the old one. The trend of change for computer users is more than the people belongs to any other field of life. The computer monitors have a special role in the use of the computer as the user gets every output on it. In order to give a better experience to the user, advanced technologies are being introduced and the new monitors are light in weight, better resolution, vivid colors and harmless to the eyes. If you’re thinking to buy a new monitor, then you must know the difference between LCD, LED, and CRT monitors.
Types of Monitors
1. Cathode Ray Tube Monitors
(CRT Monitors) are the conventional computers, large in size and have wide viewing angles. The working process of CRT is very simple in which the Cathode Ray Tube moves an electron gun to and fro across the screen. The beam collides on the phosphor dots present on the screen and emits light. The beam actives the pixels and makes an image on the screen.
Benefits of CRT Over LCD and LED
The
display quality of LED is age and temperature dependent while CRT has
no such kind of issue. Moreover, LED is expensive and inaccessible to
everyone. Similarly, LCD monitor doesn’t support black and white feature
and also has less response time. On the contrary, CRT gives true black color and has a high response time. CRT monitors are cheap and accessible to everyone.
2. Liquid Crystal Diode Monitors
2. Liquid Crystal Diode Monitors
An LCD monitor is the advanced form of CRT monitors. A Cold cathode ray, the fluorescent panel are two major components of the LCD. The cold cathode
ray technology is used in LCD which emits electrons and light up the
fluorescent coated monitor screen. The process is known as backlighting.
The second component is a fluorescent panel, which is made of liquid
crystal. Liquid Crystal determines is current sensitive and determines
the number of electrons to pass through the screen to make the shape and
image of an object.
Benefits of LCD Over CRT and LED monitors
Unlike
CRT monitors, LCD monitors are slim, occupy less space and consume less
energy. The large screen area makes it perfect for playing games,
watching movies while the size of the CRT monitor is always less than
the specified size on the paper as its frame around the glass screen
covers more than one-inch space. The flat Screen screen displays the
perfect image while its harmless for the eyes as it emits very small
part of the radiation. The feature of an auto button
lets the user resize the screen size to make images sharp and flexible.
Moreover, it’s free from the burn-in issue which is a major drawback of
CRT and Plasma monitors. Unlike LED monitors, LCD monitors are
affordable and accessible for everyone.
3. Light Emitting Diode Monitors
Light Emitting Diode (LED)
is an improved version of LCD monitor and manufacturers have tried to
eliminate the drawbacks of LCD monitors. The both monitors are based on
the same display technology and provide better resolution. However, the
difference comes on backlighting as LCD monitors use Cold Cathode
Fluorescent Light and LED monitors are based on light emitting diode.
The backlighting impacts badly on the image and decreases its sharpness
and brightness. WLED and RGB LED are the two types of LED monitors,
depending on the way LED placed in the panel.
Benefits of LED over CRT and LCD Monitors
LED
monitors give a high-quality image with vibrant colors and viewing
comfort. LCD monitors are unable to display black and white image while
LED monitors are capable of producing true black hues. It consumes less
electrical energy than CRT and LCD monitors as a cold cathode
fluorescent lamp is embedded in the panel. The absence of mercury makes
it eco-friendly while zero percent flickering removes the chances of
strain on the eyes.
Conclusion
CRT, LCD, and LED have their own specifications, pros and cons. Before buying the monitor, one should be particular about his or her requirements. Notice your budget, space in the home and core features on which you can’t compromise. No doubt, it will be a lucrative deal if one buys the monitor after analyzing the above-mentioned features.
