What is OLED TV : Things You Should Know About OLED

What is OLED TV

OLED TVs can give you a bright picture, with smooth motion, vibrant colors and is much slimmer than LED-backlit LCD TVs.
Nowadays, many of the TV brands are developing OLED TV sets which include Panasonic, Sony, LG at reasonable and affordable prices. LG is the stronger and prolific in this area. Some of the smaller brands are also getting into the market. Phillips already makes OLED TVs, and Hisense is all set to release its first by the end of this year.

Samsung is also steadfast in its belief that its quantum technology which will provide the best possible picture quality.

What’s so special about OLED TV?

OLED TVs has individual organic cells behind its screen which produce their source of light just like the standard LED-backlit TVs. OLED TVs has a large number of advantages for both quality and design:

  • Smooth motion: Motion looks good on OLED TVs, with blurring and hardly even on the fast-moving action. This feature is useful for gamers. So TV with smooth motion high is the best 4k TV for gaming.
  • Viewing angle: the viewing angle on OLED is outstanding. Also when a person is watching from a wide range of perspective, the picture will remain solid like a rock with excellent contrast and accurate colors.
  • Deep blacks: OLED sets can turn individual LED off when displaying black, rather than merely directing light away from different part of the screen, as LCDs do, which means that they can achieve intense black color.
  • Energy use: OLED TVs were initially developed to use less power than similar sized LED-backlit LCD sets.
  • Super thin screen: With no need for a backlight OLED screens can be even smaller than most of the smartphones. In 2018, LG revealed the OLED W model- w large 65-inch set that is just half the thickness of an Apple iPhone 7.

What is OLED TV 

OLED stands for Organic Light Emitting Diode. Every pixel in an OLED screen is made up of a material that glows when you switch it on. A kind of heating element in the toaster, but with less amount of heat and better resolution. This effect is called electroluminescence which is one of those words that is big, but make sense: electro for electricity, a lumen for light and essence for well.

The specific electroluminescent material which is used in OLED displays is organic compounds, which means they contain carbon with a mixture of some other ingredients as well. Each color requires a different set of natural elements.

The main effect is that each part of a tiny OLED pixel in the screen creates light which depends on how much electric current you send it. Lots of presents, lots of light. No current no light. What’s more, that is one of the keys to OLED magnificent quality picture.

What’s the future for OLED?

OLED is an expensive technology that even after several years it is still providing difficult for manufacturers to get it right.

What’s the difference between OLED and LED?

OLED stands for Organic Light-Emitting Diode, with “organic” refers to the carbon film that is inside the panel before the glass screen. OLED panels emit its light when an electric current is passed through it, whereas cells in a LED display also requires an external source of light like a dim backlight for brightness.
This means whether an image is white or black, it is being lit by the same brightness across the screen panel. Organic Light reduces the hotspots or areas of super bright light because the actual light source illuminating them is so uniform.

This all started ten years back when engineers in some of the giant companies like Sony and Samsung introduced an array of LEDs as a backlight, which means if a particular part of the screen was black than those LEDs behind that portion could be turned off to make it appear sharper and blacker.

This is the best solution than a CCFL backlight, but it still has some issues. The result is an effect which is called ‘blooming’ whereas LED light from bright portions of the image bleeds over into areas of blackness.

This is what makes a difference between OLEDs from LCD/LED displays.


An OLED TV display is that every individual organic pixel which can create its light and color output. OLED TV means pure, perfect black which can be produced. OLED screens can even achieve deeper blacks than plasma TVs while avoiding the picture noise which is associated with plasma technology. OLED TVs also offer superior viewing angle performance compared to that LED panels that suffer luminance degradation when viewed from a wide range of angle.

What is a Megapixel : Proper Megapixel for Good Picture

Nowadays, there is a habit where everyone wants to capture every moment anytime and anywhere, and most of them instantly upload to social media. In this situation, the presence of the right camera is essential. Megapixel has become the central measurement of the camera.

When people want to buy a camera, the first thing they consider is the number of megapixels, or maybe they think that their camera phone will be better if it has larger megapixel. If you think so, means that you don’t understand at all about the megapixel in a digital camera.

What is a Megapixel?

It’s not wrong if you think that a good camera is the one which has the most massive megapixel. But, remember that a megapixel is a unit that shows the resolution of images which is produced by a camera through the sensor. A single megapixel amounts to precisely one million pixels in an image. If you know that width and height in pixels of an image created by your camera, the quality of the camera is not always better with the more substantial megapixel.

Megapixel is a measure of amount, not quality. You require a specific number of megapixels relying upon the way you need to share the photograph whether it is in print or to share via web-based networking media. The number of pixels in camera doesn’t say much about the quality of the image they can capture. The quality of the camera depends on its components overall.
Quality is about camera’s optics, image sensor design, firmware, engineering, and yes its pixels but not its megapixel count. The picture sensor is the core of your camera which contains the variety of pixels. So, people who believe that megapixel determines the quality of the camera is just a myth.

Does the larger megapixel camera make the image better?

No, because the quality of picture determined by the quality of the sensor. Image sensors have different size. The bigger the picture sensor, the bigger the pixels can be, and the more photons each can gather. The outcome is a photo that is cleaner, with less picture graininess, and regularly a more remarkable separation and depiction of features and shadows.

If it compares, a camera which has 6 megapixels with a more significant physical sensor will produce a better picture than a 6 megapixels camera with a small physical sensor. Like Nikon D4 DSLR with 16.2 megapixels which has Full Frame, FX is superior compared with Nikon D3300 with 24.2 megapixels which has a short DX crop factor sensor version.

To get a thought of any camera’s sensor measure, take a gander at the distance across of the focal point. Propelled compacts reflect less cameras and semipro, and expert DSLRs come furnished with significantly more considerable sensors extending in estimate from the little one to a nearly gigantic “full-outline” sensor of around 1.5 by 1 inches found in first class DSLRs. Along these lines, every single other thing being equivalent, a 8-megapixel DSLR will deliver far superior pictures than a 8-megapixel smaller camera, much the same as the 8-megapixel conservative will catch preferable pictures over your 8-megapixel Smartphone.

So, what is the effect of megapixel on the quality of picture? Pixel is the point (DOT) as the image shaper. One of the significant influences of megapixel is in photo detail. The larger megapixel will make the picture detail better.

How Many Megapixels is suitable for the camera?

It depends on how you need the megapixel. If you want to print a picture in a banner or big size, so you’ll need a larger megapixel camera. For example, a view from 8-megapixel camera allows you to produce a maximum size reaching 3264 x 2444 pixels. At this size, you can get maximum print an image with quality awake about 10.89 x 8.17 inches or equivalent 27.6 x 20.7cm. But if you are rarely to print a copy in large size, the gigantic megapixel seems useless for you. Especially for you who only share the images to the social network. The most massive amount of megapixel will make you inconvenient because you have to do more cropping fro upload.

Having more pixels than you need hurt image quality. That’s because when you upload an overly broad picture to social media, your image will be downsized automatically, randomly delete pixels without the smarts to understand what might be critical in the film. Moreover, models with more massive megapixels than you need also take much longer to upload and might even fail partway through. Then this extra- large image files will quickly fill up storage space with unnecessary data that you probably won’t need, use or want.

So, the amount of megapixel for good camera is depending on how you need the megapixel.

How many megapixels do you need for good prints?

To start with, decide the span of you need to print, for instance, 4 x 6 inches or 8 x 10 inches, and so forth. At that point, duplicate the width by 300 and the tallness by 300, which will give you the size with respect to pixels. (300 ppi, pixels per inch is prescribed for good-quality prints.) Therefore, a 8 x 10-inch print would be 2,400 x 3,000 pixels.

Duplicate the width (in pixels) by the stature (in pixels). So for that 8 x 10-inch print, it would be 2400 x 3000, which levels with 7.2 million pixels.

After that, divide the result by 1 million then you get the number of megapixels you need to make a good print. It means, the base determination you’ll need your camera to have is 7.2 megapixels.

How many megapixels do you need for social media upload?

Like many people right now prefer to upload their photos to social media than a plan to print the images. In this case, your megapixel requirements will be far less. A Twitter photo, for example, measures just 375 x 375 pixels, which equals a mere 0.15 megapixels. A Facebook timeline photo, at 960 x 720, requires 0.69 megapixels.

What’s the largest-size photo I can upload to Instagram?

Instagram has maximum resolution supports about 2048 x 2048 on iOS; it varies on Android. However, Instagram scales photos down to a width of 1080 pixels. If you share a picture that’s less than 320 pixels wide, Instagram will enlarge it to 320 pixels.

Well, that’s all about a camera megapixel. Determine the megapixel that you need correctly to get a good camera.

You may consider enhancing the sky by using a filter like a polarising filter that can add colour and contrast or either in post-production.

2. For Beautiful Landscape Pictures to Look for a Focal Point

What is the focal point? The focal point or a point of focus is defined as the centre of activity or interest. But it doesn’t mean entirely centred in your frame. A focal point is the one object in your structure which makes up the majority of what the photograph is about. All kinds of photography must have a focal point, so it is with landscape photography. Without the focal point, your image will look empty, and the eye’s viewer can get lost in a photograph. They can move on quickly. So, the focal point provides a story from your image for your viewer. The focal point can a building or structure, a striking tree, rock formation, or a silhouette etc. Remember the rule of thirds might; it’s not only about what the focal point is but where you place the focal point.

You need to keep the balance because when you press the shutter, any camera can join having a little shaken this tripod will help you. Also, consider using a cable or wireless shutter release mechanism for extra camera stillness.

5. Landscape Photography Tips : Maximize the Depth of Field (DoF)

The depth of Field (DoF) is the sharpness of your image. Landscape photography has the sharpness end to end. The sharpness result is depending on your type of camera, aperture, and focal distance. To get greater depth of field set the smaller hole. Remember that smaller hole means less light come into your image sensor, so it says you need to compensate either by increasing your ISO or lengthening your shutter speed or both them.

6. Landscape Photography Tips :Capture Nature Movement

Maybe some people thought that landscape photography is calm, serene, and passive environments. But actually, you can add drama and create a point of interest in your landscape image. They can be waves on a beach, wind in trees, birds flying overheads, moving clouds etc. Generally, for capturing this movement, you will need to look at longer shutter speed. Therefore, you need additional equipment like filter and tripod.
If you successfully capture it, your landscape May look has a healthy mood. But sometimes, people will say “but, it’s not like the real,” whose care? It’s not a documentation photo.

7. Landscape Photography Tips : Let’s Work with The Weather

10. Landscape Photography Tips : Think about Horizons

However, it’s heard like an old tip, but you cannot miss it. Consider the horizon on two fronts before you take a landscape shot whether it is straight or compositionally. The background is the line that appears as the boundary between sky and earth. It will be apparent when you take a picture of the beach or sea. While you can always straighten images later in post-production, it’s easier if you get it right in camera.
Remember the rule of thirds; it works here.

11. Change Your Perspective to Get Landscape images

How to Make Your Desktop Look Cool With Screensaver

Today I’m going to tell you how to make this very simple and modern looking desktop. All right so we’re over at my setup, and the first step is going to be just fine a suitable and a nice-looking wallpaper and screensaver. I’m liking the whole sunset and the cool tones it has going on but you know if you find like a simple looking one. It’s make these effects look a lot better.

How to Make Your Desktop Look Cool

How to Make Your Desktop Look Cool Using Rainmeter

So for the majority of this article, you’re going to see it’s scaled to this 21 by nine ratio because my monitors are 34 40 by 14 40 apiece. So this is how it looks for me. Just as a reference for you guys. So to get this all started the program we’re going to be using is called Rainmeter. It’s straightforward go there and download the latest link that’s available.
This is going to kick everything off. So when you run Rainmeter it’s mostly going to let you add skins and like widgets to your desktop. You can see in the right-hand corner already up top it does have things like you know the time date CPUs age ring usage just stuff like that. Those are just little like default once we go ahead and disable those or unload those.

I will tell you the ones that I used or the ones I think to look best for this nice modern looking desktop. You can see it gives you the options this drop-down menu to enable certain things. This is just the very bare-bones stuff in rainmeter, but the possibilities are there if you want to use those. We’re going to use ones from external websites and creators and.

The first one is going to be called limit, and this is probably one of my favorites especially with this screensaver. You can install it, and it will then appear right in your Rainmeter menu. They’re going to have specific things you can go in and ability like the time, the date, the weather and some stuff like that along with the music player but just for the ones that I picked I wanted to go with the time and the date. You can see they do install them in the top right-hand corner by default, but you can move them around.

Now what I like about limit is quints identity the colors they use for the clock and the date match our wallpaper almost perfectly. You can see that the watches are kind of like filling up each second on the 19 hand. That’s going to give you pretty much account of the 60 seconds in the minute. Same with the date on the right as the day progresses so we’ll kind of the meter for that, and it does go up real time for both the hour hand and the date which is cool. You can customize the colors if you want to the text file but I’m going to leave them default because like I said it just matches this wallpaper beautifully.

Music Visualizer

Next up is going to be our music visualizer and that’s going to be from fountains of color, and mostly this is going to add a music visualizer in bars on to your desktop. Much like the others are going to give you some options here but just for the fountains of color I’m going to go with clone because that’s going to provide you with the
bar visualizer on the top. This is going to work for any audio coming out of your PC whether you’re watching you know on a YouTube video listen to music on Spotify or any external music player whatever sound comes through your speakers or your headphones usually it’s going to be now visualized.

This can be completely customized to your liking. If you click on the witch laser itself or to bring up a little menu, we can change the colors have it do random colors or pick a few colors that you want it to pretty much pulse to you also do things that change the number of bars. So if you wanted to be across your entire desktop shift the shift in length the decibel at which they peak or which they descend to entirely up to you but for me, I was going to leave it default because I don’t mind the way it looks. So this is my current go to with the wallpaper limit and fountains of color installed. I’m a big fan of it. This is going to be pretty much my default wallpaper from here on out.
