Major technologies are CRT, LCD and its derivatives (Quantum dot display, LED backlit LCD, WLCD, OLCD), Plasma, and OLED and its derivatives (Transparent OLED, PMOLED, AMOLED). An emerging technology is Micro LED and cancelled and now obsolete technologies are SED and FED.

We come across Liquid Crystal Display (LCD) displays everywhere around us. Computers, calculators, television sets, mobile phones, and digital watches use some kind of display to display the time.

An LCD screen is an electronic display module that uses liquid crystal to produce a visible image. The 16×2 LCD display is a very basic module commonly used in DIYs and circuits. The 16×2 translates a display of 16 characters per line in 2 such lines. In this LCD, each character is displayed in a 5×7 pixel matrix.

Contrast adjustment; the best way is to use a variable resistor such as a potentiometer. The output of the potentiometer is connected to this pin. Rotate the potentiometer knob forward and backward to adjust the LCD contrast.

A 16X2 LCD has two registers, namely, command and data. The register select is used to switch from one register to other. RS=0 for the command register, whereas RS=1 for the data register.

Command Register: The command register stores the command instructions given to the LCD. A command is an instruction given to an LCD to do a predefined task. Examples like:

Data Register: The data register stores the data to be displayed on the LCD. The data is the ASCII value of the character to be displayed on the LCD. When we send data to LCD, it goes to the data register and is processed there. When RS=1, the data register is selected.

Generating custom characters on LCD is not very hard. It requires knowledge about the custom-generated random access memory (CG-RAM) of the LCD and the LCD chip controller. Most LCDs contain a Hitachi HD4478 controller.

CG-RAM address starts from 0x40 (Hexadecimal) or 64 in decimal. We can generate custom characters at these addresses. Once we generate our characters at these addresses, we can print them by just sending commands to the LCD. Character addresses and printing commands are below.

LCD modules are very important in many Arduino-based embedded system designs to improve the user interface of the system. Interfacing with Arduino gives the programmer more freedom to customize the code easily. Any cost-effective Arduino board, a 16X2 character LCD display, jumper wires, and a breadboard are sufficient enough to build the circuit. The interfacing of Arduino to LCD display is below.

The combination of an LCD and Arduino yields several projects, the most simple one being LCD to display the LED brightness. All we need for this circuit is an LCD, Arduino, breadboard, a resistor, potentiometer, LED, and some jumper cables. The circuit connections are below.

Monitor ports have changed over the years. Not only can they carry increasingly complex data, but they can also charge and power the devices that they connect. Like any technology, monitor ports are undergoing a continuing evolution to improve image quality and power efficiency.

Technology evolves every day. New and improved devices, formats, and media types seem to pop up every day, too. Keeping up with it all can be a full-time job. Monitor ports are the hidden masterpieces that maximize the output of our evolving devices and media.

Monitor ports are points of connection that enable various flows of data and information.It is essential to understand what monitor ports are and how they work to determine which ones will best serve your needs. Staying current with these advances in technology will ensure you can maximize the use of your device to enjoy the best digital experience.

HDMI ports have their drawbacks, however, which makes other options a better choice at times. The main limitation of the HDMI cable is the distance in which its transmissions can travel (about 15 meters or 50 feet is considered the upper limit). Likewise, they are quite bulky. As technology has advanced, smaller versions of HDMI cables, usually called Micro or Mini, were invented to accommodate our mobile devices and tablets, but the standard size is pretty big as far as modern cables go.

Capable of carrying signals at resolutions as high as 2560 x 1600, it helped maximize the digital quality of flatscreen LCD monitors and modern video graphics cards. It has been a top choice for HDTVs and other high-end video displays for TV, movies, and DVDs, while also supporting both computer monitors and projectors. In recent years, DVI has become the standard digital interface for the computer market.

The introduction of the USB-C port clearly indicates that technology is advancing rapidly, becoming more efficient, versatile, powerful, and universalized. Finding the right monitor port still depends on your specific needs.

Considering the direction that technology is moving in, and the speed it’s accelerating, it’s a fascinating time in which we, as consumers, need to adapt to newer technologies.

In the past, monitor manufacturers relied on the V-Sync standard to ensure consumers and business professionals could use their displays without issues when connected to high-performance computers. As technology became faster, however, new standards were developed — the two main ones being G-Sync and Freesync.

V-Sync, short for vertical synchronization, is a display technology that was originally designed to help monitor manufacturers prevent screen tearing. This occurs when two different “screens” crash into each other because the monitor’s refresh rate can’t keep pace with the data being sent from the graphics card. The distortion is easy to spot as it causes a cut or misalignment to appear in the image.

Although V-Sync technology is commonly used when users are playing modern video games, it also works well with legacy games. The reason for this is that V-Sync slows down the frame rate output from the graphics cards to match the legacy standards.

Although the technology works well with low-end devices, V-Sync degrades the performance of high-end graphics cards. That’s the reason display manufacturers have begun releasing gaming monitors with refresh rates of 144Hz, 165Hz, and even 240Hz.

Released to the public in 2013, G-Sync is a technology developed by NVIDIA that synchronizes a user’s display to a device’s graphics card output, leading to smoother performance, especially with gaming. G-Sync has gained popularity in the electronics space because monitor refresh rates are always better than the GPU’s ability to output data. This results in significant performance issues.

For example, if a graphics card is pushing 50 frames per second (FPS), the display would then switch its refresh rate to 50 Hz. If the FPS count decreases to 40, then the display adjusts to 40 Hz. The typical effective range of G-Sync technology is 30 Hz up to the maximum refresh rate of the display.

The most notable benefit of G-Sync technology is the elimination of screen tearing and other common display issues associated with V-Sync equipment. G-Sync equipment does this by manipulating the monitor’s vertical blanking interval (VBI).

To keep pace with changes in technology, NVIDIA developed a newer version of G-Sync, called G-Sync Ultimate. This new standard is a more advanced version of G-Sync. The core features that set it apart from G-Sync equipment are the built-in R3 module, high dynamic range (HDR) support, and the ability to display 4K quality images at 144Hz.

Released in 2015, FreeSync is a standard developed by AMD that, similar to G-Sync, is an adaptive synchronization technology for liquid-crystal displays. It’s intended to reduce screen tearing and stuttering triggered by the monitor not being in sync with the content frame rate.

Since this technology uses the Adaptive Sync standard built into the DisplayPort 1.2a standard, any monitor equipped with this input can be compatible with FreeSync technology. With that in mind, FreeSync is not compatible with legacy connections such as VGA and DVI.

As FreeSync is a standard developed by AMD, most of their modern graphics processing units support the technology. A variety of other electronics manufacturers also support the technology, and with the right knowledge, you can even get FreeSync to work on NVIDIA equipment.

Although FreeSync is a significant improvement over the V-Sync standard, it isn’t a perfect technology. The most notable drawback of FreeSync is ghosting. This is when an object leaves behind a bit of its previous image position, causing a shadow-like image to appear.

A key difference between FreeSync and FreeSync 2 devices is that with the latter technology, if the frame rate falls below the supported range of the monitor, low framerate compensation (LFC) is automatically enabled to prevent stuttering and tearing.

Typical LCDs are edge-lit by a strip of white LEDs. The 2D backlighting system in Pro Display XDR is unlike any other. It uses a superbright array of 576 blue LEDs that allows for unmatched light control compared with white LEDs. Twelve controllers rapidly modulate each LED so that areas of the screen can be incredibly bright while other areas are incredibly dark. All of this produces an extraordinary contrast that’s the foundation for XDR.

With a massive amount of processing power, the timing controller (TCON) chip utilizes an algorithm specifically created to analyze and reproduce images. It controls LEDs at over 10 times the refresh rate of the LCD itself, reducing latency and blooming. It’s capable of multiple refresh rates for amazingly smooth playback. Managing both the LED array and LCD pixels, the TCON precisely directs light and color to bring your work to life with stunning accuracy.

To successfully screen mirror, you need a TV or monitor that supports this technology. Meaning that it can receive content via built-in technology like AirPlay or Mirecast, or by using a screen-mirroring adapter and receiver kit.

How to use it:You can screen cast with technology like Google’s Chromecast or similar streaming devices and applications. Once you have successfully cast the content onto your TV, you will have to control everything from your TV not your phone or computer.

How to use it:The person sending and the person receiving must both have a device that support screen sharing technology or it will not work. You can achieve this by using video call software.

At the end of the day, these terms are not strict. Most often, people will get the gist of what you are talking about. However, it doesn’t hurt to know the differences between these mirroring, casting and sharing technologies so that you can benefit from the best technology for your situation!

Pew Research Center has long studied the changing nature of parenting and family dynamics as well as the adoption of digital technologies. This report focuses on how children engage with digital technologies, screens and social media, as well as parents’ attitudes about these behaviors, their concerns about their child’s use of technology, and their own assessment of their parenting and experiences with digital tech. These findings are based on a survey conducted March 2-15, among 3,640 U.S. parents who have at least one child or children ages 17 and under. This includes those who took part as members of Pew Research Center’s American Trends Panel (ATP), an online survey panel that is recruited through national, random sampling of residential addresses, as well as respondents from the Ipsos KnowledgePanel. The margin of sampling error for the full sample is plus or minus 2.2 percentage points.

Parenting has never been easy. But the widespread adoption of smartphones and the rise of social media has introduced a new wrinkle to the challenges of parenthood. In fact, a majority of parents in the United States (66%) – who include those who have at least one child under the age of 18, but who may also have an adult child or children – say that parenting is harder today than it was 20 years ago, with many in this group citing technology as a reason why, according to a Pew Research Center survey conducted in March.

Several terms used in this report are related to parents, age of children and the technology adoption practices of children. This reference guide explains each term.

Engagement and interaction with digital technology among children was measured by asking parents about the devices their child “uses or interacts with.”

Parents cite a number of different reasons why they think parenting has grown more difficult over the years. Some of the most common responses tend to stress the impact of digital technology (26%), the rise of social media (21%) and how access to technology exposes children to things at a young age (14%). Other commonly cited reasons for parenting growing more difficult include changing morals and values and the costs associated with raising a child.

Parents’ assessments of their technology use vary by age. For example, parents ages 18 to 49 are more likely than those ages 50 and older to say they spend too much time on their smartphone (59% vs. 36%). Similarly, parents under the age of 50 are more likely than those ages 50 and older to say they often or sometimes feel distracted by their smartphone when spending time with their children (70% vs. 55%).

Proteome profile changes post-severe acute respiratory syndrome coronavirus 2 (post-SARS-CoV-2) infection in different body sites of humans remains an active scientific investigation whose solutions stand a chance of providing more information on what constitutes SARS-CoV-2 pathogenesis. While proteomics has been used to understand SARS-CoV-2 pathogenesis, there are limited data about the status of proteome profile in different human body sites infected by the SARS-CoV-2 virus. To bridge this gap, our study aims to characterize the proteins secreted in urine, bronchoalveolar lavage fluid (BALF), gargle solution, and nasopharyngeal samples and assess the proteome differences in these body samples collected from SARS-CoV-2-positive patients. We downloaded publicly available proteomic data from (https://www.ebi.ac.uk/pride/). The data we downloaded had the following identifiers: (i) PXD019423, n = 3 from Charles Tanford Protein Center in Germany. (ii) IPX0002166000, n = 15 from Beijing Proteome Research Centre, China. (iii) IPX0002429000, n = 5 from Huazhong University of Science and Technology, China, and (iv) PXD022889, n = 18 from Department of Laboratory Medicine and Pathology, Mayo Clinic, Rochester, MN 55905 USA. MaxQuant was used for the human peptide spectral matching using human and SARS-CoV-2 proteome database which we downloaded from the UniProt database (access date 13th October 2021). The individuals infected with SARS-CoV-2 viruses displayed a different proteome diversity from the different body sites we investigated. Overally, we identified 1809 proteins across the four sample types we compared. Urine and BALF samples had significantly more abundant SARS-CoV-2 proteins than the other body sites we compared. Urine samples had 257(33.7%) unique proteins, followed by nasopharyngeal with 250(32.8%) unique proteins. Gargle solution and BALF had 38(5%) and 73(9.6%) unique proteins respectively. Urine, gargle solution, nasopharyngeal, and bronchoalveolar lavage fluid samples have different protein diversity in individuals infected with SARS-CoV-2. Moreover, our data also demonstrated that a given body site is characterized by a unique set of proteins in SARS-CoV-2 seropositive individuals.
