LED vs QLED vs OLED: Which TV you should buy?

If You are buying a new TV or planning to buy one soon, the search for a new TV may end up jarring to you with all these technical terms like the resolution of tv, refresh rate, type of display (LED TV, QLED TV, and OLED TV) floating in the market. These marketing terms for TVs like LED, OLED, and QLED are some major display technology that you'll find in almost every commercial TV available in the market right now. And today we're going to talk about these three types of display tech you'll find in almost every TV right now.
So these three major TV displays LED, QLED, and OLED has their own pros and cons. In this article, we'll look at what these display techs are and their advantages & disadvantages and I hope that this article will help you to find your perfect TV according to your budget and preference.

LED vs QLED vs OLED TVs: Which is better and which TV you should buy?

But before we dive into LED, QLED, and OLED display technologies we must know the basics behind all of this. When the time of old CRT TVs was gone and new thin TVs started coming, this was when the LCD technology came into existence. And since the use of LCD technology in TVs is going on. So now the question arises that what is this LCD technology that put an end to CRT TVs?

What is an LCD? 

LCD which stands for Liquid Crystal Display is an electronic display tech that uses the light modulating properties of 'Liquid Crystals (LCs)'. Actually, LCDs are just thin panels with lots of liquid crystals. These liquid crystals are responsible for displaying a picture or video you see on your tv by converting electronic signals into a visual format. But liquid crystals don't have their own light source or you can say that they don't emit light directly and due to this you won't see that LCs are showing something or not.  To overcome this problem, scientists came up with an idea to provide an external light source for liquid crystals to provide a better and clear visual image. And this is where the concept of "Backlighting" was born and two types of backlighting methods came into existence.

1. CCFL Backlighting 

It was the first-ever method that was used to illuminate the LCs in LCS panels. CCFL stands for 'Cold Cathode Fluorescent Lamps' and due to short lifespan, low brightness, low luminous intensity, and being bulky or heavy, it was replaced by the LED backlighting method. 

2. LED Backlighting

As we all know, LED stands for 'Light Emitting Diode" an electronics device that emits light when hit by electric current. Backlighting provided by LEDs is much brighter, has a high luminous efficiency which provides a clear image in comparison to the CCFL backlighting method. LEDs have higher efficiency, take less energy, quite compact & light, and last longer than CCFLs.

Ok so with all these basics let's straight ahead to our today's topic LED vs QLED vs OLED TVs and which TV you should buy?

What is LED TV and What are LED displays?

LED televisions are basically an LCD television that uses LED backlighting method to illuminate the LCD display. Earlier these LED TVs were also known as LED-backlight LCD television. It is the most common and widely used display tech used in televisions. Ans this LED backlighting can be achieved by three methods and the first one is Direct backlighting in this direct backlighting method the LEDs are placed directly behind the LCS panel as a layer that illuminates the panel directly from the center. Direct backlighting produces better colors and brightness to the display but this makes the tv a bit thick and heavy. The second method is Edge backlighting in this method the LEDs are placed on the edge of displays with a diffusion panel between LCs and LEDs to provide extra illumination to the display. Edge-lit LEDs are comparatively thin and light. The third method is Full-array LED backlighting in this method LEDs are placed behind and on the edges of an LCD panel thus providing overall better illumination resulting in a brighter image and good color reproduction. Full array LED-backlit TVs are quite slim and expensive.

Advantages of LED TVs

1. Consume less power than plasma or LCD TVs
2. Produces less heat
3. Most affordable TV out there 
4. Available in all sizes 

Disadvantages of LED TVs

1. Poor Contrast level
2. Poor viewing angles

What is QLED TV and What are QLED displays?

The QLED TVs can be considered as a middle-ground between LED tv and OLED tv. The tech behind QLED TVs is actually similar to the LED TVs. 'Q' in QLED TVs stands for 'Quantum Dot'. QLED is nothing but a LED-backlit LCD TV or displays with a quantum dot layer between the LCD panel and the LED array for backlighting. The Quantum dot layer acts as a filter for backlighting illumination which provides better and more saturated colors. 

Advantages of QLED TVs

1. Better color reproduction
2. Excellent image quality
3. Less motion blur

Disadvantages of QLED TVs

1. Contrast is not good as OLED TVs
2. Sub-par black levels
3. Viewing angles are decent enough
4. Refresh rate is slow

What is OLED TV and What are OLED displays?

OLED TVs are something different from LED and QLED TVs. They need no backlighting and a quantum dot filter layer to produce life-like colors and images. In OLED TVs each pixel produces its own light when hits with an electric current. The pixels can adjust their luminous intensity and capable of a turn off completely as well to produce deeper and rich black levels. Thus provides high contrast and deep black levels resulting provide life-like images and videos. 

  Advantages of OLED TVs

1. Wide and great viewing angles
2. Perfect black levels
3. Perfect contrast 
4. Faster refresh rates 
5. No motion blur

Disadvantages of OLED TVs

1. Very Expensive
2. Can't be available in small sizes
3. Not as bright as LED or QLED TVs

So, that's all for today. Each TV tech has its advantages and downsides. OLED TVs are totally different from LED and QLED TVs with pixels that can be turned off and on individually resulting in perfect blacks and great viewing angles. On the other hand LED and QLED TVs are much brighter than OLED TVs.

RAM or Processor: What makes a smartphone fast ?

  Hello friends and welcome again to your own tech guide: Techanalysia. So today we are to going to see that, what makes a smartphone fast? Is it RAM or Processor? One can't choose between RAM and Processor while determining a device's performance. RAM or Processor: What makes a smartphone fast? The answer to the above question is, both. RAM and Processor are both responsible for the smooth and lag-free performance of your smartphone. Let's take a look at how these two play an important role in a smartphone. First thing first, the type of rams used in smartphones are DDR RAMs.  In particular, the RAM used in smartphones is technically called LPDDR RAM. This term stands for 'Lower Power Double Data Rate RAM. These LPDDR RAMs are the version of DDR RAMS specially designed for smartphones. These RAMs are optimized for low power consumption because these RAMs are used inside smartphones which are having a small battery compared to PC/Laptop in which DDR RAMs are employed. T
