FHD, WQHD, Quad HD, Ultra HD, and more FULL INFO about image resolutions
Know the meaning of the acronyms and understand the differences between each of the image resolutions For professional use or just watching Netflix , knowing your screen resolution is one of the factors to consider when investing in new equipment . Before deciding on your purchase and going around just comparing prices, check the list to understand the acronyms: HD, FHD, WQHD, WQXGA, QHD and UHD and find the best option . Basic concepts: pixel, size and resolution When we talk about screens, we need to consider two measures: size and resolution. Size: refers to the physical dimensions of the screen; Resolution: is the amount of information displayed within these size limits. The screen size is measured in inches, each measuring 2.54 centimeters . That is, a smartphone with a 5-inch screen is 12.7 centimeters (5 x 2.54). As the screens are usually rectangular, the measurement is made considering the size of the diagonal. The resolution shows us how many pixels fit on the screen. Pixels are the points that make up the image being arranged in rows and columns. In this way, the resolution will define how many pixels there are in each row (width) and each column (height). So to say that a screen has a resolution of 1280 x 720 means that it displays 1280 pixels per row and 720 pixels per column. It is important to note that the more pixels, the higher the resolution , therefore, a better image quality on your screen. 1. HD / 720p HD (High Definition, the famous High Definition) or 720p, has a resolution of 1280 x 720 pixels, and is appropriate for the aspect ratio of 16:9, whether for televisions or cell phones. It is the most basic image quality found on devices and media files. This resolution is common on TVs and monitors smaller than 40 inches, and notebooks, as the standard screen resolution is 1366 x 768 pixels. 2. Full HD / 1080p Full HD or 1080p is a screen with a resolution of 1920 x 1080 pixels, equally suited to the 16:9 aspect ratio. However, with more lines of pixels to display on the display. With the emergence of 18:9 or 21:9 screens on smartphones, new resolutions have also emerged that better accommodate these proportions. We call HD+ any resolution that is based on 720 lines, such as 1480 x 720 pixels. If the resolution is based on the 1080 lines of Full HD we call it FHD+, like 2220 x 1080 pixels. The exact number of speakers will depend on the aspect ratio of the screen and may vary slightly from manufacturer to manufacturer. Despite the emergence of 4K resolution , it is common to find devices with Full HD screens, especially on TVs and notebooks. This resolution is still widely used by streaming services, as it is not necessary to have a fast internet connection to stream. Digital TV broadcasting is also done in this resolution. List of HD, Full HD and derivatives resolutions NAME RESOLUTION HD (720p) 1280 x 720 pixels nHD 640 x 360 pixels (a quarter of HD) qHD 960 x 540 pixels (one quarter of Full HD) Full HD (1080p or FHD) 1920 x 1080 pixels QHD or WQHD…
What is QLED? Full info about display technology used in TVs
Learn the differences between QLED and Neo QLED, their relationship with Crystal UHD TVs, plus the positives and negatives. QLED or Quantum Dot Light-Emitting Diodes is one of several technologies present in current televisions that reach 4K resolution or higher. Although increasingly popular, the term still raises doubts. Understand what QLED is , how it works and the main differences from other technologies such as Neo QLED, QNED and what characteristics to look out for when choosing a new TV. What is QLED QLED can be seen as an enhancement of LCD. The quantum dots used in the technology are crystals with nanometers in diameter that emit very specific lengths of light. These nanocrystals are composed of semiconductor materials that provide a quantum confinement effect, which occurs when the material’s electrons are limited to extremely small volumes. Quantum confinement allows nanocrystals the ability to modify and adjust the wavelength of light according to their size, generating different colors without the need for chemical combinations. Although quantum dot technology received its first commercial applications in 2013, in devices such as the Sony Triluminos line , studies on quantum confinement have been going on since 1982, when Russian scientists identified the phenomenon. In devices with QLED technology, there is a structure made up of an LCD screen, a film of quantum dots and a backlight composed of LEDs that emit blue light. The backlight is the set composed of a lamp and other elements that provide the necessary light for the process of producing images in displays that do not produce their own light. LCD televisions usually use a backlight that emits white light, while QLED technology uses a blue light LED. The nanocrystals present in QLED devices are one of the technology’s differentials, because inside the film, there are specific crystals that reproduce shades of red, green and blue. This operation avoids tonal variations, producing purer, more realistic colors and brighter screens. Is QLED already the standard or are there still inferior TVs? Despite gaining popularity, QLED TVs share space with their LCD and LED older sisters. These technologies use a lighting unit and have similar characteristics, although QLED models are brighter and have a wider color gamut. In addition to these models, there are TVs with OLED technology, which produce images through another method that results in images with different characteristics. Therefore, it is a little complex to define the quality of a device, based only on the technology used. In a more basic comparison, we can say that QLED screens present more brightness and more vivid colors, while OLED screens offer deeper black levels and greater contrast, due to their individually illuminated organic diode technology that allows each pixel to be turned on or off individually. . As QLED and LED TV models need a light source to produce images, they have less precise light control than OLED models, resulting in grayer and less faithful blacks. On the other hand, QLED televisions can offer a greater color gamut, more brightness and tend to have fewer problems with reflections on the screen, something that can make them an interesting choice for brighter environments. The most important…

TOP 5 MOBILE APPLICATION FOR WEB DEVELOPER
Hello everyone. My name is Shivam. today during this video we talk about top tools for mobile developers so as an experienced developer, i’ve got seen that our dependency is either as a designer or web developer so here we’ll discuss some tools which will make some things easy and can be automated. so let’s speak about our first tool that is. 1. App Icon Maker Through app icon maker you’ll generate different size icons for Android and IOS. this is a web app so in thisyou have to upload a higher resolution logo and this will give you different size of icons for Android and IOS. and that too in respective folder and zip file will be emailed. you’ll extract this content and copy paste it in your project and use it. 2. TESTAPI.IO So our next tool is sort of helpful for a mobile developer. because as a mobile developer, we’ve to design many UI in dynamic nature meaning with server’s response that UI should be set. but sometimes APS gets delayed too so our work should not be stopped so for this I use test.api.io tool. here I create a dummy response and this provides me a dummy url and I use this dummy url as a rest API in my flutter app. I complete my dynamic UI work and once I get live app I just need to replace url. so this API may be a static API meaning json will give you a response. and get,post or delete method are supported too. You can go to this app and register your account and use this app. 3. Json-Generator So as we saw within the previous step that how we created a dummy url for rest API and used it and dummy json data was also set in it. but it’s possible that you want large amount of json data or json array. suppose you would like json array between 100-1000 length. so for that here we’ll use json generator app. so the function of json generator is that you will mention syntax of some logics and it’ll generate you random values according to logics. so what’s so special about json generator? here you’ll see some specific syntax are mentioned so it can generate values according to these syntax. even you’ll mention these values according to your app. as I’m mentioning latitude longitude here so this may generate automatically correct latitude longitude. you can apply some logic in generation tag meaning like skipping some values or null return. this can instantly generate a 1000 length data in some seconds. and use it in rest API and may create dynamic UI in app. 4. QuickType So far we created dummy url to use it in rest API and used dummy json data to use it in rest API. now we’ve to show that data in mobile. so to point out that data we will make a model class where we store our whole API data. so if it’s a small json object, there is no issue but when we have pairs of large keys of value in one json object, then we’ve to mention it manually. In this many manual errors can occur too. So for this, i exploit QuickType. In QuickType, you’ve got to mention json response on the left side. you have to select programming language meaning if you’re working in java or dart. and this…

What is deepfake and why should you care?
Learn more details about the technology that uses AI to change people’s faces in videos and manipulate audios Have you ever thought about seeing your face in a random video? Or hear your voice saying things you would never say? Well, this is possible with a technology called deepfake, which allows this manipulation, especially in videos, in a compelling way. See below for more details on what a deepfake is and why you need to be concerned about this technique. What is deepfake, and why should you be concerned (Vitor Pádua / Tecnoblog) Deepfake uses Artificial Intelligence to change people’s faces in videos and synchronize lip movements, expressions, and other details, in some cases with impressive and compelling results. This wave of swapping people’s faces in videos is not new. But in December 2017, a Reddit user called deepfakes took it a step further. Using open source Artificial Intelligence and Machine Learning tools such as Keras and TensorFlow (the latter from Google), he created an algorithm to train a Neural Network to map one person’s face onto another’s body, frame by frame. Instead of relying on manual editing as in the past, the user, through the tool (which was named Deepfake), only needs a source to recognize the model of the “victim’s” face and map the structure of the target head and make the overlap. The software can adjust the movement of the original video to the new beginning, including facial expressions and lip movements. In the beginning, Deepfake required advanced knowledge on the user’s part. Still, when others created applications and systems capable of automating the entire process, the tool was massively used for evil: dozens of adult videos edited with the software soon began to appear, with the face of actresses and artists. Deepfake’s “joke” wasn’t limited to adult videos; however: there are several creations that put celebrity faces in movies they weren’t present in. However, the possibilities for using the software are numerous and harmful. Even Mark Zuckerberg was the target of a fake video. Some examples of easily accessible deepfake tools are the Reface application, the DeepSwap, and DeepFakes Web sites, and the FaceApp and DeepFaceLab programs. It is important to note that deepfake is different from shallow fake. The premise is the same, but the difference is in the quality. In superficial pretender, the rate of manipulation is lower, making identification easier. The types of deep fakes As much as the focus of deepfake is the exchange of faces in videos, anyone who thinks that the practice is restricted to that is wrong. The technique is also used for audio manipulation, where recordings can be created that simulates a particular person’s voice, a type of deepfake that can be easily shared in messengers such as WhatsApp. In addition, we can already come across textual deepfakes, with typewriters generated by artificial intelligence; deepfakes on social networks, for the creation of fake profiles on the internet; and real-time deepfakes, in which it is possible to change the face in live broadcasts, a technique allowed by the DeepFaceLive software, for example. Potential risks of deepfakes Although the main target of the community around the tool…
