LED, OLED & QLED Television — Which Is The Best TV According To Your Budget? 2 726

Did you think buying a TV is going to be super easy? That all you’ve to do is go to the electronics store, browse a couple of smart television models, and take your favorite pick?

Well, oh boy, you’re in for a surprise!

The minute you walk into the TV section, you’re going to be bombarded with a ton of terms that you’ve no idea what they mean! But three words that you really want to know about in advance are LED, OLED and QLED.

This is really going to help make your TV-shopping experience easier and you’ll be able to make a more informed decision too.

Needless to say, the first and most important feature you want on your television is kickass picture quality. Most manufacturers today have similar requirements. They all come in the same kinds of sizes and shapes, but what differs are the picture processors and panels—something that can make all the difference in your TV.

Let’s identify the similarities first. Be it LED, QLED or OLED, all three types of screen technologies support 4K resolution and accompany 4K color-boosting tech like HDR, HDR10+, and Dolby Vision.

Let’s look into the difference between the three types of TVs and see what’re the trade-offs between each of them

LED Televisions

These are your regular television sets – the ones you’ve probably seen the most.

Short for Light Emitting Diode, LED TVs are often considered as a competing concept with LCD Display. But in truth, LED TVs are actually an identical display technology to LCD.

Unlike LCDs that use a single backlight to illuminate the pixels, LED TVs have LED lights the make up the back-light which illuminates the pixels.

But, because the light comes from an external source, this increases the overall size of the TV. If you use an LED TV in pitch-black darkness, then you’ll notice uneven brightness and blotches on the screen, with a lack of shadow detail in the darker areas of the screen.

But other than that, the images on an LED TV are quite bright and clear, displaying pictures in excellent vivid colors!

What’s OLED TV Technology?

If you’ve never had the chance to experience an OLED TV, then it’s high time you do! We promise you that it’s going to be an absolutely ‘Woah’ moment for you!

We’re talking smooth, colorful, and contrasting picture display that you’re definitely going to fall in love with. So, the real question is, is this the flat TV technology we’ve been waiting for?

The term OLED stands for Organic Light Emitting Diode. This latest technology doesn’t use the back-light. It emits it’s own light and each pixel self-illuminates, giving you control of individual pixels of the images.

Organic films are placed between semiconductors in an OLED panel. Here, the films are supplied with electricity that allows them to function on an individual level. The processes use relatively less power to enhance the brightness, thus making total black possible.

This means that videos that feature both complete darkness and high brightness look realistic. Imagine watching a lifelike starry night on a TV – that’s what your OLED tech can do!

They’re, however, quite expensive and there isn’t enough information on how long will the OLED panels last. Not to mention, they’re only available in four sizes on the market – 55-, 65-, 77-, and 88- inch.

With OLED TVs, you can expect to see unparalleled picture quality, quick response time, and the cherry on top, their panel manufacturing is more environmentally friendly!

What’s QLED TV Technology?

Short for Quantum-Dot Light Emitting DiodeQLED TVs are the new range of LED TVs introduced by Samsung. This QLED technology is nothing like OLED tech.

Unlike OLEDs, QLEDs don’t have self-emissive panels. Instead, they use LEDs along the edge to light up the pixels. These TVs use a quantum dot color filter which helps to create a much brighter image than that of OLED TVs. This means that you can enjoy a more lifelike color palette – especially for colors like greens, reds, and cyans.

However, the response time, the black-level quality, and infinite contrast ability aren’t as good as that of OLEDs. The organic nature of OLEDs means that they can turn off unused pixels completely. But, QLEDs and LEDs of even the best quality with effective local dimming let some light through.

Because QLED is an LCD-based technology, some areas of the screen may appear brighter than others. Even the best kinds of LCDs tend to fade and lose their colors unless viewing it from a sweet spot that’s directly in front of the TV. OLEDs, on the other hand, have uniform screens that maintain fidelity from most angles.

And if you’re someone who’s looking to enjoy a larger (or smaller) screen, then you’ll be happy to know that QLEDs come in all kinds of sizes. From as small as 43-inch to as big as 98-inch, you can find them in almost any size you want.

FINAL CALL: Which TV Should You Buy?

Other than Samsung Smart TV that sells both OLED and QLED tech, most manufacturers deal with one of the two technologies.

LG is the only company that’s making OLED panels, whereas Walton Smart TV is dealing with high-quality panels. All other brands use the technology on license and try to add their own genius o give their models an edge.

Your purchasing decision will largely depend on the price. If you’ve got money and really want to spend it on a magnificent TV experience, then you should consider OLEDs.

Besides the price, consider what features you want in your television set and make a choice accordingly. You’ve got all the information you need in this article. Just go through it and take a pick!

Covid-19: 7 Ways to Stay Protected From Black Fungus or Mucormycosis Infection! 0 83

When the Government is taking several initiatives to curb the Indian delta variant of the coronavirus down, the shocking news of newly spreaded black fungus has raised new angst concern across the countrymen. The infection of mucormycosis or black fungus can cause your eye damage permanently and eventually attack other major organs of the body dangerously. To put a full stop in this destruction, awareness and suggestions from the health experts can be pretty much enough.

What is Black Fungus?

Black Fungus meaning can be appropriate as a fungal disease. According to medical science, it’s also recognized as mucormycosis. Mucormycosis is a very rare infection. Black fungus infection on skin occurs when you come in contact with a fungus called mucor. The fungus is commonly found in soil, plants, fertilizers and rotting fruits and vegetables.

Fungus can exist naturally in soil and air. Even black fungus stays in the human body so naturally that it can stay normal in the nose and mucus of healthy people. This fungus infects the sinuses, brain and lungs. As the Covid-19 infected people’s lungs are weak, black fungus can pose a serious risk to them.

What Kind of Symptoms of Black Fungus Infection Can Appear?

Black Fungus in eyes is one of the most common black fungus cases discovered in the Indian Delta Plus variant Covid-19 or coronavirus.

Symptoms commonly seen in patients with black fungus include:

  • Nasal congestion and bleeding from the nose
  • Eye pain and eye swelling
  • Eyelid drooping
  • Blurred vision and from which the vision completely disappears later
  • Black spots appear around the skin of the nose

What Are the Necessary Precautions to be Protected From Black Fungus?

According to the United States Centers for Disease Control and Prevention (U.S. CDC), it is quite impossible to avoid areas where the fungus is present. Doctors signifies the fungus that cause mucormycosis are very common in the environment.

As black fungus treatment and any kind of black fungus medicine aren’t discovered yet, those with weakened immune systems may take precautionary steps to reduce the risk of mucormycosis infection.

These precautions to get protection from black fungus are highly recommended:

  1. The U.S. Centers for Disease Control and Prevention or U.S. CDC suggests avoiding areas where there is a lot of dust. If it is not possible to avoid those places, then use the N95 mask.
  2. Avoid direct contact with the buildings which have been damaged by water due to natural disasters. The CDC says fungal infections can occur from these places.
  3. Should be careful enough so that any infection can’t happen on your skin. If it is cut somewhere on the skin or any injury to any part of your body, extra care should be taken so that it does not come in contact with dust and dirt.
  4. In case of Covid-19 patients, diabetes should be controlled as per the advice of the doctors.
  5. The patient should be careful enough when using steroids. Sometimes excessive use of steroids can make diabetes uncontrollable. As a result, the risk of infection with black fungus will be higher.
  6. Need to maintain cleanliness while giving oxygen to the patient.
  7. Always maintain cleanliness when using face masks.

The US Centers for Disease Control and Prevention mentions that precautionary measures against mucormycosis are not fully enough yet. Hence, we can do our best as much as we can to stay protected from black fungus. Awareness can save many lives and so there’s no alternative to always being careful always.

Covid-19: What Should You Do Initially When the Oxygen Level of Your Body Flows Down? 0 65

One of the biggest harms of Covid-19 in the human body is that many patients have low oxygen levels in their blood. A healthy person’s blood oxygen level should be 90 to 100 percent. Hence, the real problem starts when oxygen goes below 90 percent. That’s why doctors advise the covid-19 affected people to measure the oxygen level with a pulse oximeter every day on a regular basis. And the oxygen measurement process with pulse oximeters is very easy and simple. If the oxygen level is too low, then the condition is higher critical and the patient needs to be given oxygen through high flow nasal cannula supervised by specialist doctors.

What Happens When Oxygen Decreases in Blood

Generally, Pulse Oximeter is as handy as to check the oxygen level in blood any time. But there are other ways to find out the lack of oxygen in blood without using pulse oximeters.

If the oxygen level is low in blood, the head may feel dizzy, the body may feel weak, breathing may be difficult. Many can become unconscious.

When the oxygen level in the blood drops below a certain level, the brain also lacks oxygen which is very dangerous. Breathing problems and lack of oxygen to the brain are the biggest concerns.

Necessary Tips to Follow While Oxygen Level Reduces In Blood Below 90%

Loosen the Clothing

Majority face trouble breathing in tight clothing. Many people can’t breathe comfortably as such clothes are tight along the chest that prevents the lung muscles from expanding.

And if the body is already in a deficient oxygen condition, then even ordinary clothing can cause pain while breathing. When oxygen is depleted in the body of a covid-19 patient, loosen the dress at the very beginning.

If you are wearing something tight, take it off. Take off your underwear and tight fit pants. Also remove the face mask as the mask can also be responsible for creating difficulty in breathing.

No Rush Needed

No one should rush if the patient is alone or if someone else is helping him/her.

All the organs of the body need oxygen. Walking and even eating something increases the body’s demand for oxygen.

So stop walking and stay calm. Refrain from eating anything.

Lay Upside Down

Lay the patient upside down on the bed. The patient needs to lie on chest and keep trying to take a deep breath slowly.

It is beneficial because a large part of the lungs are located on the back of the human body. As a result of lying on the chest, the back part of the lungs gets enough oxygen easily. At least corona patients can get some benefit from this technique.

To reduce the breathing issue, it’s also suggested to lay on the right side for at least 30 minutes and upto 2 hours. And also sitting in (30-60) degree angle with a back support can be useful to breathe partially.

Breathing Exercises

To keep the lungs healthy, doctors are now advising everyone to do some efficient lung exercises.

This advice is also given to healthy people because coronavirus infects the lungs. Patients with covid-19 can also perform breathing exercises if they have difficulty in breathing.

Learn a very simple breathing exercise. Breathe deeply through the nose at a long length. Hold the air in the lungs for seven to ten seconds or as long as possible and slowly exhale. This exercise needs to be done several times.

Say ‘No’ to the Crowd

Avoid too many people near you if you have difficulty breathing. Crowds can reduce oxygen and increase carbon dioxide in your home. Keep the windows opened to maintain the natural air flow in the house.

These tips may offer you temporary relief if you have mild problems.

Arrange High Flow Oxygen

If the situation worsens then there is no alternative but to provide oxygen. In that case, the wise decision is to take the patient to the hospital or bring the oxygen cylinder home. Of course the patient should be treated at home with the help of a trained guy. 

If any critical condition occurs, for example high flow nasal cannula oxygen system may be needed, then don’t waste time at home. Shift the patient to the hospital immediately. If needed, try to arrange an ICU bed on emergency basis.
