LCDs vs LEDs vs OLEDs : WHICH IS BETTER?

Display panels are used in a variety of devices. Whether it be a smartphone, TV, or computer display, it needs to have a good panel. Manufacturers and companies put a lot of effort into making these display panel PCs and they promote their technology on the basis of different points too. In order to have a rich viewing experience, customers focus on the pricing, contrast, and visibility factors of a particular panel PC. This helps them to make the right choice while buying any device with a great display. However, there are plenty of display innovations available in the market and all of them have their unique features. In this article, we will go through some of the most commonly used display panels and their features.

Liquid Crystal Displays (LCDs)

LCD panel PCs are more commonly known as the display technology that revolutionized the display industry. Before LCDs, most TV screens used CRT panels. Not only were they bulky, but they also didn’t provide crisp and clear images. LCDs changed that. They were much thinner, and lighter. LCD panels primarily use backlight technology. The backlight shines light from a cold cathode fluorescent lamp which presents images on the screen. The LCD technology did not just use raw electricity to power itself, it benefited from the backlight. This reduced the electricity bill significantly for the users.

Light Emitting Diodes (LEDs)

LED panel PCs are the same as LCDs. But instead of relying on a CCFL backlight, the display technology uses LEDs. They are very helpful because LEDs do not take much electricity which shows up as lesser bills. They also have a longer lifespan compared to LCDs.

In-Plane Switching LCD (IPS)

IPS is a type of LCD technology that benefits from the polarization properties of LCD panels. They have better viewing angles compared to normal LCD panels. They are also commonly used on phone screens although they are being slowly replaced by AMOLED. IPS LCD panel PC has a disadvantage in that it does not have a high refresh rate and therefore can feel a bit unresponsive on smartphones. They do not have great contrast either.

Organic Light-Emitting Diodes (OLEDs)

OLED panel PCs do not use any kind of backlighting whether it be CCFL or LED. They offer higher contrast which creates crisper and clear images. Therefore, they produce better images with much deeper blacks. Just like LEDs, they do not consume much power and are very suitable for higher resolution videos such as 4K. However, they do not last as long as LEDs. 

Quantum LEDs (QLEDs) is a technology being promoted by Samsung which is slowly getting closer to the image quality offered by OLEDs. But, QLEDs fail to create bright visible images in well-lit rooms.

Active Matrix OLEDs or AMOLEDs are smartphone displays that have a much higher refresh rate and feel very smooth to interact with. They provide higher contrast and better images. The only problem is the smaller lifespan which makes it a secondary option for those who prefer IPS LCDs on their phone. 

Whether it be LCDs, a battle of contrast between LEDs and QLEDs, or a preference for higher refresh rates as seen in AMOLEDs, display technology for panel PC is constantly improving and it is an undeniable fact. The more efficient these display panels become, the better for the viewers to enjoy high-resolution videos with crisp and clear renders.
