Modern devices with display screens come with different resolutions – HD, UHD, FHD, 4K, 3D, smart, 4K Ultra smart, and much more. However, the two most common screen types are LCD and LED. Confused about the differences between the two? Worried if one is better than the other?
Do not worry. We bring to you the clear cut differences between the two screens via this article. Now we understand deference between LCD vas LED Monitor.
We shall talk about the working of the two screens, their structure and find out if one is better than the other. But before getting into that, let us first learn what the two types of screens are in detail.
All LED monitors can be categorized as LCD monitors but this is not true vice versa. Both the displays use liquid crystals and backlight to create an image but while LEDs use light emitting diodes for backlight, LCD displays use fluorescent backlights.
LED monitors usually have superior picture quality and come with variable backlight configurations. One configuration may create better backlight than the other. Also check the best monitor under 10000 budget.

LCD displays vs. LED displays
Till mid 2010s, plasma displays were all the rage for good resolution after which LCDs took over. Using similar technologies but different configurations, LEDs emerged in the market and since then people swear by its resolution. Technically, LED monitors can also be called “LED LCD monitors” as it is just an upgrade on LCD screens.
Are they the same thing?
Like we said before, all LED monitors can be categorized as LCD monitors but this is not true vice versa. One is an upgrade on the other and there are major differences in the structure, configuration and resolution that the screens provide individually.
LCD (Liquid Crystal Display) screens employ “cold cathode fluorescent lamps (CCFLs)” as its backlights which are fluorescent lights are. They are evenly placed behind the screen to deliver lighting on the display when forming an image across it. With this consistent lighting, all parts of the monitor are equally bright.
LED (Light Emitting Diode) monitors don’t use fluorescent lighting for their backlight but instead use “light emitting diodes” which is also from where this type of screen gets its name. These diodes are small lights with two configurations – full-array backlighting (evenly spread LEDs arranged in zones that can be dimmed) and edge lighting (LEDs placed at the edge of the display screen instead of behind it).
OLED or “Organic Light Emitting Diode” monitors have a light source for each pixel which can be individually turned off and the liquid crystal can be closed. These monitors provide you with better black colors, deeper contrast ratios and way better image quality.
Quantum Light Emitting Diode or QLED monitor screens come with each pixel having a “quantum dot” which is basically a tiny phosphor particle that glows when any kind of light is shined upon it.
The light is shined and not produced from the pixel itself as LEDs are not very good for emitting bright light, especially when it is in the form of the color white. This is why they need phosphorus coatings that give it the blue-ish shade which is closer to white but still not white.
The quantum dots thus come with red and green coatings to compensate for the blue light.
Display screens, their structure and how exactly they really work are complicated especially with the variety we have to choose from. We do hope that this article helped you in deciding the screen you should go for.
