Displays are used to present visual information; they are created to ensure that visual information sharing process is simplified. Displays can affect resolution, power consumption, battery life, size, and even durability of your devices and with the release of Nintendo switch OLED imminent (October 8 2021) boasting a titular new OLED display, a departure from the LCD screens of previous versions . It wouldn’t hurt to know how these displays compare with one another.
- Liquid Crystal Display (LCD)
- Light Emitting Diode (LED)
- Organic Light Emitting Diode (OLED)
- Plasma
- Cathode Ray Tubes (CRT)
- Quantum Dot Light-Emitting Diode (QLED)
1. LCD
LCD is known as ‘Liquid Crystal Display’ as stated in the name it is made of liquid crystals. It is the most used monitor worldwide, as it requires less space, consumes less power, and produces relatively less heat than an old CRT screens.
LCD screens are thinner and much lighter in size and weight than CRT monitors. Due to this, it competes with LED and OLED in the market.
This display was first used in laptops, and then later introduced for Desktop Computers ranging from 17 inches to 60 inches. Being that these monitors need less space and are light in weight, they do not create any trouble in transporting and moving them from one place to another.
By consuming less energy it not only provides better graphics quality but also a fine brighter screen display. In this way, LCDs are very economical in the terms of costs, energy, image quality, and features with integration devices like speakers via ports.
2. LED
LED’s full form is ‘Light Emitting Diode’ it’s major competition is with LCDs and Plasma Monitors. LED monitors are slightly curved or flat panel displays that use light-emitting diodes for backlighting on the screen instead of cold cathode fluorescent (CCFL) for back-lighting.
LED display with its 4k resolution is brighter than other displays. LED monitors use less power than LCDs and are widely used by gamers for playing high graphics and HD games.
The advantage of LEDs is that they produce images with higher contrast and vivid colors. LEDs are more durable as compared to LCD and CRT Monitors.
LEDs screen delivers flicker-free image which lessens the eye strain and fatigue, and headaches.
Also LEDs do not contain hazardous chemicals and some of it’s part are recyclable, therefore they are considered to have a less environmental impact than LCDs.
The price rate of LED monitors can be a little expensive though and so not considered affordable.
3. OLED
OLED stands for “Organic Light Emitting Diode“. As the name suggests, it is made of organic material (such as carbon, plastic, wood, and polymers), that is used to convert electric current into light.
OLEDs are used in displays of television, computer screen, game consoles, PDAs, or even in the latest smartphones. It can be thinner or lighter with a higher contrast ratio than LCDs. Since these LEDs are capable enough to produce a lot of different colored light, they can be used directly to produce the correct color and there is no need for any backlight, which saves power and also requires less space. The OLED display is considered great for watching movies.
OLED Monitors are considered the best display technology ever because of their characteristics like wide viewing angles, picture quality, outstanding contrast levels, No ghosting, fast response, and perfect contrast and brightness.
Although OLEDs allow for higher contrast its not as bright as LCD displays because it doesn’t have a backlight. Also, you should protect the monitor from water as it can damage the OLED screen. The other disadvantages of the OLED monitor right now are its short life expectancy than LCDs and LEDs and the high price rate in the market currently.
4. Plasma
The Plasma monitor panel (PDP) is made of Plasma technology is another latest type of computer monitor technology. Display of plasma made with cells. These cells are filled with ‘electrically charged Ionized Gas‘. Such cells are called Plasma.
The basic idea behind its invention is that it illuminates tiny colored fluorescent lights that create image pixels. It has the advantage of slimness, a plasma display is flat rather than slightly curved as an LCDs has. It cuts down image distortion and glare through its perfect flat screens.
A plasma display offers a good response, superior performance, time, and a much wide viewing angle as compared to LCDs. Plasma displays come in sizes up to 60 inches that can be considered the best home theater and HD television.
The major disadvantages of plasma monitors are their limited production and screen sizes. Plasma monitors are heavier in size and consume more electricity, on average than LCD monitors.
5. CRT
CRT means “Cathode Ray Tube”. Its main part is the Cathode Ray tube which is called the “Generally Picture tube”. CRT monitors are much heavier in size as compared to LCD and LED monitors. Due to being heavy, moving and transporting them from one place to another is a lot of trouble. Also, they need more space for installation.
Over the last few decades CRTs have disappeared from the market, because display manufacturers switched their production lines from CRT 4:3 displays to LCD 16:9 widescreen displays in order to survive the transition to the digital world widescreen television of LEDs or LCDs.
CRT monitors are not only bulky but also consume a lot of electricity.
6. QLED
QLED, or quantum dot light-emitting diode displays.
These quantum dots can essentially produce a brighter image and deeper colors. And because of how efficient they are, very little light is lost. Usually, because the backlight is a bright blue, the quantum dots are green and red. The QLED is a Samsung development and although other companies are free to use the quantum dot technology, they have to refrain from referring to it as QLED display.
Final Notes
The QLED and the OLEDs are considered to have an edge over the other screens displays, but the overall it still depends on the users preference, depending on which screen you go for you would be making some kind of trade off, whether it’s brightness, contrast or electricity consumption. For instance OLEDs produce true blacks, and as a result, higher contrast, and they have better off-angle viewing But QLED displays are brighter and cheaper than OLED panels.
