Interactive touchscreen experiences are a fantastic way to connect with customers, whether at events, tradeshows and exhibitions or in your showroom or marketing suite. They are intuitive to use, look great, by creating a sense of WOW, and can help to project a brand as innovative and dynamic.

And where businesses may not be able to meet with customers or attend events, interactive experiences are ideal for staying connected with customers. Depending on the software, they can be shared over the web or used to create virtual demo spaces for customers to explore in their own time.

The hardware – This is the physical touchscreen itself and also the PC the visual experience runs on. There are lots of different types of touchscreens, from wall-mounted to touch-tables, stand-mounted as well as custom-built enclosures.

The visual experience – This is the content shown on the screen, which people will interact with. It’s this visual content that you’ll need software to create.

Before embarking on a project, it’s important to clarify your business objectives. This is crucial as the answers may determine what software you use to create your experience. If you choose the wrong software option at the beginning you may have to start the whole project again to achieve the result you need.

When developing any Interactive experience – whether that be a sales tool or touchscreen experience – for our clients, we run an Initial workshop – the Customer-First Blueprint® – to reflect upon our client’s objectives. It helps clients to think about:

Specialist software, which is designed for building touchscreen experiences and interactive digital signage. We create our own bespoke software and also use Showpad, Intuiface, Tumult Hype and Ventuz

We have had years of developing experience using all of the above for clients. Whilst many of the software options can be developed in-house, our experienced team of designers and developers have encountered the highs and lows of all these solutions for every scenario. Resulting in a high-quality touchscreen experience in a fraction of the time.

A Progressive Web App(PWA) uses the same language, HTML, Javascript and CSS, as a website and the functionality is built in a very similar way. It can be run over the internet and uses a standard browser. We use Google Chrome in Kiosk mode, which enables the experience to be run full-screen, so you don’t see the browser menu and scroll bars.

But that is where the similarities between a Progressive Web App and a website end. A PWA is a very sophisticated option, allowing you to create almost any type of experience you can imagine. You can include videos, PDFs, presentations, 3D models, Augmented Reality and Virtual Reality into the experience. Unlike a website, a PWA is built with a Touchscreen user in mind.

A touchscreen is a very different user experience for the customer, even for those of us used to Smartphones. You’re generally dealing with a much bigger screen, which impacts on the layout. Your audience will be using their finger rather than a mouse to move around and interact. Clear prompts and navigation are essential to make it obvious to the user what they need to do. Small differences can have quite far-reaching consequences.

A PWA can be run through any browser making it accessible. It can also work offline, so an internet connection isn’t necessary for the touchscreen experience to work

It can easily connect to other systems to pull or push information backwards and forwards. For example, it could connect to an organisation’s Content Management System so any content within those systems can be automatically pulled into your touchscreen experience. Similarly, if you collect customer information through your touchscreen this can be automatically posted back into your CMS for future marketing or sales campaigns

There are specialist software applications for creating touchscreen experiences. Programs such as Intuiface and ShowPad are well-established applications for creating professional touchscreen experiences.

Experiences can be created for any touchscreen type from tablets up to video walls, so you can make experiences as large as you like to cover multiple displays.

Some are only designed to work at one screen resolution, they are not responsive systems (Intuiface is an example of this). This means if you are going to use your touchscreen experience on a large touchscreen, a laptop and tablets most likely they will have different screen ratios (16×9, 16×10 or 4×3 etc.) So although the experience will still work, it won’t fill the screen on all those devices

The editing software has a license fee to use and each device that will run the touchscreen experience also needs a licence. So, if you have 10 touchscreens running your experience you’ll need 10 licences, so it could be quite expensive.

You simply drag and drop the information you need into the template of the web portal and connect your digital signage screens over the internet to the portal, which then displays your content on your digital screens.

You are limited by the functionality of the system though, so it will only do certain things within the template but some do have a lot of options to cover most use cases

As it is templated, you won’t have a lot of control over the branding and layout of the experience> But bear in mind, this may not be an issue when the end goal is to create a very simple user experience

Interactivity is very limited so the user experience can be quite simple and a little boring, you certainly wouldn’t call them immersive. So, if you’re trying to create a personalised customer experience through a touchscreen we’d avoid these systems.

Don’t laugh or scoff but PowerPoint has very sophisticated interactive features which will let you create touchscreen experiences. You can put a lot of things into them such as video, images, PDFs and 3D elements.

Again, we recommend using a presentation design agency or touchscreen specialist. It would still be quite an advanced presentation you’d be creating, and you may not have the in-house skills yourself.

We hope this has been useful and we’ve managed to shed some light on the various options available when creating an interactive touchscreen experience.

We are platinum certified Intuiface creative partner (one of only 2 in the UK) and a creative partner of Showpad so have plenty of expertise to help with any questions.

Rather than plug your Raspberry Pi into a TV, or connect via SSH (or remote desktop connections via VNC or RDP), you might have opted to purchase a Raspberry Pi touchscreen display.

Straightforward to set up, the touchscreen display has so many possibilities. But if you"ve left yours gathering dust in a drawer, there"s no way you"re going to experience the full benefits of such a useful piece of kit.

The alternative is to get it out of the drawer, hook your touchscreen display to your Raspberry Pi, and reformat the microSD card. It"s time to work on a new project -- one of these ideas should pique your interest.

Let"s start with perhaps the most obvious option. The official Raspberry Pi touchscreen display is seven inches diagonal, making it an ideal size for a photo frame. For the best results, you"ll need a wireless connection (Ethernet cables look unsightly on a mantelpiece) as well as a Raspberry Pi-compatible battery pack.

In the example above, Belkin WeMo switches and a Nest thermostat are manipulated via the Raspberry Pi, touchscreen display, and the InControlHA system with Wemo and Nest plugins. ST:TNG magic comes from an implementation of the Library Computer Access and Retrieval System (LCARS) seen in 1980s/1990s Star Trek. Coder Toby Kurien has developed an LCARS user interface for the Pi that has uses beyond home automation.

Building a carputer has long been the holy grail of technology DIYers, and the Raspberry Pi makes it far more achievable than ever before. But for the carputer to really take shape, it needs a display -- and what better than a touchscreen interface?

Ideal for entertainment, as a satnav, monitoring your car"s performance via the OBD-II interface, and even for reverse parking, a carputer can considerably improve your driving experience. Often, though, the focus is on entertainment.

Now here is a unique use for the Pi and its touchscreen display. A compact, bench-based tool for controlling hardware on your bench (or kitchen or desk), this is a build with several purposes. It"s designed to help you get your home automation projects off the ground, but also includes support for a webcam to help you record your progress.

The idea here is simple. With just a Raspberry Pi, a webcam, and a touchscreen display -- plus a thermal printer -- you can build a versatile photo booth!

Various projects of this kind have sprung up. While the versions displayed above uses a thermal printer outputting a low-res image, you might prefer to employ a standard color photo printer. The wait will be longer, but the results better!

Projects along these lines can also benefit from better use of the touchscreen. Perhaps you could improve on this, and introduce some interesting photo effects that can be tweaked via the touchscreen prior to printing?

How about a smart mirror for your Raspberry Pi touchscreen display project? This is basically a mirror that not only shows your reflection, but also useful information. For instance, latest news and weather updates.

Naturally, a larger display would deliver the best results, but if you"re looking to get started with a smart mirror project, or develop your own from scratch, a Raspberry Pi combined with a touchscreen display is an excellent place to start.

Many existing projects are underway, and we took the time to compile six of them into a single list for your perusal. Use this as inspiration, a starting point, or just use someone else"s code to build your own information-serving smart mirror.

Want to pump some banging "toons" out of your Raspberry Pi? We"ve looked at some internet radio projects in the past, but adding in a touchscreen display changes things considerably. For a start, it"s a lot easier to find the station you want to listen to!

This example uses a much smaller Adafruit touchscreen display for the Raspberry Pi. You can get suitable results from any compatible touchscreen, however.

Alternatively, you might prefer the option to integrate your Raspberry Pi with your home audio setup. The build outlined below uses RuneAudio, a Bluetooth speaker, and your preferred audio HAT or shield.

Requiring the ProtoCentral HealthyPi HAT (a HAT is an expansion board for the Raspberry Pi) and the Windows-only Atmel software, this project results in a portable device to measure yours (or a patient"s) health.

With probes and electrodes attached, you"ll be able to observe and record thanks to visualization software on the Pi. Whether this is a system that can be adopted by the medical profession remains to be seen. We suspect it could turn out to be very useful in developing nations, or in the heart of infectious outbreaks.

We were impressed by this project over at Hackster.io, but note that there are many alternatives. Often these rely on compact LCD displays rather than the touchscreen solution.

Many home automation systems have been developed for, or ported to, the Raspberry Pi -- enough for their own list. Not all of these feature a touchscreen display, however.

One that does is the Makezine project below, that hooks up a Raspberry Pi running OpenHAB, an open source home automation system that can interface with hundreds of smart home products. Our own guide shows how you can use it to control some smart lighting. OpenHAB comes with several user interfaces. However, if they"re not your cup of tea, an LCARS UI theme is available.

Another great build, and the one we"re finishing on, is a Raspberry Pi-powered tablet computer. The idea is simple: place the Pi, the touchscreen display, and a rechargeable battery pack into a suitable case (more than likely 3D printed). You might opt to change the operating system; Raspbian Jessie with PIXEL (nor the previous desktop) isn"t really suitable as a touch-friendly interface. Happily, there are versions of Android available for the Raspberry Pi.

This is one of those projects where the electronics and the UI are straightforward. It"s really the case that can pose problems, if you don"t own a 3D printer.

Adding a display to your Arduino can serve many purposes. Since a common use for microcontrollers is reading data from sensors, a display allows you to see this data in real-time without needing to use the serial monitor within the Arduino IDE. It also allows you to give your projects a personal touch with text, images, or even interactivity through a touch screen.

Transparent Organic Light Emitting Diode (TOLED) is a type of LED that, as you can guess, has a transparent screen. It builds on the now common OLED screens found in smartphones and TVs, but with a transparent display, offers up some new possibilities for Arduino screens.

Take for example this brilliant project that makes use of TOLED displays. By stacking 10 transparent OLED screens in parallel, creator Sean Hodgins has converted a handful of 2D screens into a solid-state volumetric display. This kind of display creates an image that has 3-dimensional depth, taking us one step closer to the neon, holographic screens we imagine in the future.

Crystalfontz has a tiny monochrome (light blue) 1.51" TOLED that has 128x56 pixels. As the technology is more recent than the following displays in this list, the cost is higher too. One of these screens can be purchased for around $26, but for certain applications, it might just be worth it.

The liquid crystal display (LCD) is the most common display to find in DIY projects and home appliances alike. This is no surprise as they are simple to operate, low-powered, and incredibly cheap.

This type of display can vary in design. Some are larger, with more character spaces and rows; some come with a backlight. Most attach directly to the board through 8 or 12 connections to the Arduino pins, making them incompatible with boards with fewer pins available. In this instance, buy a screen with an I2C adapter, allowing control using only four pins.

Available for only a few dollars (or as little as a couple of dollars on AliExpress with included I2C adapter), these simple displays can be used to give real-time feedback to any project.

The screens are capable of a large variety of preset characters which cover most use cases in a variety of languages. You can control your LCD using the Liquid Crystal Library provided by Arduino. The display() and noDisplay() methods write to the LCD, as shown in the official tutorial on the Arduino website.

These simple boards are made up of 7 LEDs (8 if you include the dot), and work much like normal LEDs with a common Anode or Cathode connection. This allows them to take one connection to V+ (or GND for common cathode) and be controlled from the pins of your Arduino. By combining these pins in code, you can create numbers and several letters, along with more abstract designs—anything you can dream up using the segments available!

These tiny LCD screens are monochrome and have a screen size of 84 x 48 pixels, but don"t let that fool you. Coming in at around $2 on AliExpress, these displays are incredibly cheap and usually come with a backlight as standard.

Depending on which library you use, the screen can display multiple lines of text in various fonts. It"s also capable of displaying images, and there is free software designed to help get your creations on screen. While the refresh rate is too slow for detailed animations, these screens are hardy enough to be included in long-term, always-on projects.

For a step up in resolution and functionality, an OLED display might be what you are looking for. At first glance, these screens look similar to the 5110 screens, but they are a significant upgrade. The standard 0.96" screens are 128 x 64 monochrome, and come with a backlight as standard.

They connect to your Arduino using I2C, meaning that alongside the V+ and GND pins, only two further pins are required to communicate with the screen. With various sizes and full color options available, these displays are incredibly versatile.

For a project to get you started with OLED displays, our Electronic D20 build will teach you everything you need to know -- and you"ll end up with the ultimate geeky digital dice for your gaming sessions!

These displays can be used in the same way as the others we have mentioned so far, but their refresh rate allows for much more ambitious projects. The basic monochrome screen is available on Amazon.

Thin-film-transistor liquid-crystal displays (TFT LCDs) are in many ways another step up in quality when it comes to options for adding a screen to your Arduino. Available with or without touchscreen functionality, they also add the ability to load bitmap files from an on-board microSD card slot.

Arduino have an official guide for setting up their non-touchscreen TFT LCD screen. For a video tutorial teaching you the basics of setting up the touchscreen version, YouTuber educ8s.tv has you covered:

https://www.anrdoezrs.net/links/7251228/type/dlg/sid/UUmuoUeUpU43826/https://www.youtube.com/supported_browsers?next_url=https%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3DIcIY2pWursc

With the touchscreen editions of these screens costing less than $10 on AliExpress, these displays are another great choice for when you need a nice-looking display for your project.

Looking for something a little different? An E-paper (or E-ink depending on who you ask) display might be right for you. These screens differ from the others giving a much more natural reading experience, it is no surprise that this technology is the cornerstone of almost every e-reader available.

The reason these displays look so good is down to the way they function. Each "pixel" contains charged particles between two electrodes. By switching the charge of each electrode, you can influence the negatively charged black particles to swap places with the positively charged white particles.

Now that you have an idea of what is out there, why not incorporate a screen into your DIY smart home setup? If retro gaming is more your thing, why not create some retro games on Arduino?

In this Arduino touch screen tutorial we will learn how to use TFT LCD Touch Screen with Arduino. You can watch the following video or read the written tutorial below.

For this tutorial I composed three examples. The first example is distance measurement using ultrasonic sensor. The output from the sensor, or the distance is printed on the screen and using the touch screen we can select the units, either centimeters or inches.

The third example is a game. Actually it’s a replica of the popular Flappy Bird game for smartphones. We can play the game using the push button or even using the touch screen itself.

As an example I am using a 3.2” TFT Touch Screen in a combination with a TFT LCD Arduino Mega Shield. We need a shield because the TFT Touch screen works at 3.3V and the Arduino Mega outputs are 5 V. For the first example I have the HC-SR04 ultrasonic sensor, then for the second example an RGB LED with three resistors and a push button for the game example. Also I had to make a custom made pin header like this, by soldering pin headers and bend on of them so I could insert them in between the Arduino Board and the TFT Shield.

Here’s the circuit schematic. We will use the GND pin, the digital pins from 8 to 13, as well as the pin number 14. As the 5V pins are already used by the TFT Screen I will use the pin number 13 as VCC, by setting it right away high in the setup section of code.

As the code is a bit longer and for better understanding I will post the source code of the program in sections with description for each section. And at the end of this article I will post the complete source code.

I will use the UTFT and URTouch libraries made by Henning Karlsen. Here I would like to say thanks to him for the incredible work he has done. The libraries enable really easy use of the TFT Screens, and they work with many different TFT screens sizes, shields and controllers. You can download these libraries from his website, RinkyDinkElectronics.com and also find a lot of demo examples and detailed documentation of how to use them.

After we include the libraries we need to create UTFT and URTouch objects. The parameters of these objects depends on the model of the TFT Screen and Shield and these details can be also found in the documentation of the libraries.

Next we need to define the fonts that are coming with the libraries and also define some variables needed for the program. In the setup section we need to initiate the screen and the touch, define the pin modes for the connected sensor, the led and the button, and initially call the drawHomeSreen() custom function, which will draw the home screen of the program.

So now I will explain how we can make the home screen of the program. With the setBackColor() function we need to set the background color of the text, black one in our case. Then we need to set the color to white, set the big font and using the print() function, we will print the string “Arduino TFT Tutorial” at the center of the screen and 10 pixels down the Y – Axis of the screen. Next we will set the color to red and draw the red line below the text. After that we need to set the color back to white, and print the two other strings, “by HowToMechatronics.com” using the small font and “Select Example” using the big font.

Next is the distance sensor button. First we need to set the color and then using the fillRoundRect() function we will draw the rounded rectangle. Then we will set the color back to white and using the drawRoundRect() function we will draw another rounded rectangle on top of the previous one, but this one will be without a fill so the overall appearance of the button looks like it has a frame. On top of the button we will print the text using the big font and the same background color as the fill of the button. The same procedure goes for the two other buttons.

Now we need to make the buttons functional so that when we press them they would send us to the appropriate example. In the setup section we set the character ‘0’ to the currentPage variable, which will indicate that we are at the home screen. So if that’s true, and if we press on the screen this if statement would become true and using these lines here we will get the X and Y coordinates where the screen has been pressed. If that’s the area that covers the first button we will call the drawDistanceSensor() custom function which will activate the distance sensor example. Also we will set the character ‘1’ to the variable currentPage which will indicate that we are at the first example. The drawFrame() custom function is used for highlighting the button when it’s pressed. The same procedure goes for the two other buttons.

drawDistanceSensor(); // It is called only once, because in the next iteration of the loop, this above if statement will be false so this funtion won"t be called. This function will draw the graphics of the first example.

So the drawDistanceSensor() custom function needs to be called only once when the button is pressed in order to draw all the graphics of this example in similar way as we described for the home screen. However, the getDistance() custom function needs to be called repeatedly in order to print the latest results of the distance measured by the sensor.

Ok next is the RGB LED Control example. If we press the second button, the drawLedControl() custom function will be called only once for drawing the graphic of that example and the setLedColor() custom function will be repeatedly called. In this function we use the touch screen to set the values of the 3 sliders from 0 to 255. With the if statements we confine the area of each slider and get the X value of the slider. So the values of the X coordinate of each slider are from 38 to 310 pixels and we need to map these values into values from 0 to 255 which will be used as a PWM signal for lighting up the LED. If you need more details how the RGB LED works you can check my particular tutorialfor that. The rest of the code in this custom function is for drawing the sliders. Back in the loop section we only have the back button which also turns off the LED when pressed.

In order the code to work and compile you will have to include an addition “.c” file in the same directory with the Arduino sketch. This file is for the third game example and it’s a bitmap of the bird. For more details how this part of the code work you can check my particular tutorial. Here you can download that file:

If you’ve ever begun searching for a new computer screen, chances are you’ve probably come across the term IPS. It’s at this point that you may be asking yourself, what is an IPS monitor? And how do I know if an IPS monitor is right for me?

So, why is this important? A monitor’s panel technology is important because it affects what the monitor can do and for which uses it is best suited. Each of the monitor panel types listed above offer their own distinctive benefits and drawbacks.

Choosing which type of monitor panel type to buy will depend largely on your intended usage and personal preference. After all, gamers, graphic designers, and office workers all have different requirements. Specific types of displays are best suited for different usage scenarios.

The reason for this is because none of the different monitor panel types as they are today can be classified as “outstanding” for all of the attributes mentioned above.

Below we’ll take a look at how IPS, TN, and VA monitors affect screen performance and do some handy summaries of strengths, weaknesses, and best-case uses for each type of panel technology.

IPS monitors or “In-Plane Switching” monitors, leverage liquid crystals aligned in parallel to produce rich colors. IPS panels are defined by the shifting patterns of their liquid crystals. These monitors were designed to overcome the limitations of TN panels. The liquid crystal’s ability to shift horizontally creates better viewing angles.

IPS monitors continue to be the display technology of choice for users that want color accuracy and consistency. IPS monitors are really great when it comes to color performance and super-wide viewing angles. The expansive viewing angles provided by IPS monitors help to deliver outstanding color when being viewed from different angles. One major differentiator between IPS monitors and TN monitors is that colors on an IPS monitor won’t shift when being viewed at an angle as drastically as they do on a TN monitor.

IPS monitor variations include S-IPS, H-IPS, e-IPS and P-IPS, and PLS (Plane-to-Line Switching), the latter being the latest iteration. Since these variations are all quite similar, they are all collectively referred to as “IPS-type” panels. They all claim to deliver the major benefits associated with IPS monitors – great color and ultra-wide viewing angles.

When it comes to color accuracy, IPS monitors surpass the performance of TN and VA monitors with ease. While latest-gen VA technologies offer comparative performance specs, pro users still claim that IPS monitors reign supreme in this regard.

Another important characteristic of IPS monitors is that they are able to support professional color space technologies, such as Adobe RGB. This is due to the fact that IPS monitors are able to offer more displayable colors, which help improve color accuracy.

In the past, response time and contrast were the initial weakness of IPS technology. Nowadays, however, IPS monitor response times have advanced to the point where they are even capable of satisfying gamers, thus resulting in a rising popularity in IPS monitors for gaming.

With regard to gaming, some criticisms IPS monitors include more visible motion blur coming as a result of slower response times, however the impact of motion blur will vary from user to user. In fact, mixed opinions about the “drawbacks” of IPS monitor for gaming can be found all across the web. Take this excerpt from one gaming technology writer for example: “As for pixel response, opinions vary. I personally think IPS panels are quick enough for almost all gaming. If your gaming life is absolutely and exclusively about hair-trigger shooters, OK, you’ll want the fastest response, lowest latency LCD monitor. And that means TN. For the rest of us, and certainly for those who place even a modicum of importance on the visual spectacle of games, I reckon IPS is clearly the best panel technology.” Read the full article here.

IPS monitors deliver ultra-wide 178-degree vertical and horizontal viewing angles. Graphic designers, CAD engineers, pro photographers, and video editors will benefit from using an IPS monitor. Many value the color benefits of IPS monitors and tech advances have improved IPS panel speed, contrast, and resolution. IPS monitors are more attractive than ever for general desktop work as well as many types of gaming. They’re even versatile enough to be used in different monitor styles, so if you’ve ever compared an ultrawide vs. dual monitor setup or considered the benefits of curved vs. flat monitors, chances are you’ve already come into contact with an IPS panel.

TN monitors, or “Twisted Nematic” monitors, are the oldest LCD panel types around. TN panels cost less than their IPS and VA counterparts and are a popular mainstream display technology for desktop and laptop displays.

Despite their lower perceived value, TN-based displays are the panel type preferred by competitive gamers. The reason for this is because TN panels can achieve a rapid response time and the fastest refresh rates on the market (like this 240Hz eSports monitor). To this effect, TN monitors are able to reduce blurring and screen tearing in fast-paced games when compared to an IPS or VA panel.

On the flip side, however, TN panel technology tends to be ill-suited for applications that benefit from wider viewing angles, higher contrast ratios, and better color accuracy. That being said, LED technology has helped shift the perspective and today’s LED-backlit TN models offer higher brightness along with better blacks and higher contrast ratios.

The greatest constraint of TN panel technology, however, is a narrower viewing angle as TN monitors experience more color shifting than other types of panels when being viewed at an angle.

Today’s maximum possible viewing angles are 178 degrees both horizontally and vertically (178º/178º), yet TN panels are limited to viewing angles of approximately 170 degrees horizontal and 160 degrees vertical (170º /160º).

In fact, TN monitor can sometimes be easily identified by the color distortion and contrast shifting that’s visible at the edges of the screen. As screen sizes increase, this issue becomes even more apparent as reduced color performance can even begin to be seen when viewing the screen from a dead-center position.

For general-purpose use, these shifts in color and contrast are often irrelevant and fade from conscious perception. However, this color variability makes TN monitors a poor choice for color-critical work like graphic design and photo editing. Graphic designers and other color-conscious users should also avoid TN displays due to their more limited range of color display compared to the other technologies.

TN monitors are the least expensive panel technology, making them ideal for cost-conscious businesses and consumers. In addition, TN monitors enjoy unmatched popularity with competitive gamers and other users who seek rapid graphics display.

Vertical alignment (VA) panel technology was developed to improve upon the drawbacks of TN. Current VA-based monitors offer muchhigher contrast, better color reproduction, and wider viewing angles than TN panels. Variations you may see include P-MVA, S-MVA, and AMVA (Advanced MVA).

These high-end VA-type monitors rival IPS monitors as the best panel technology for professional-level color-critical applications. One of the standout features of VA technology is that it is particularly good at blocking light from the backlight when it’s not needed. This enables VA panels to display deeper blacks and static contrast ratios of up to several times higher than the other LCD technologies. The benefit of this is that VA monitors with high contrast ratios can deliver intense blacks and richer colors.

Contrast ratio is the measured difference between the darkest blacks and the brightest whites a monitor can produce. This measurement provides information about the amount of grayscale detail a monitor will deliver. The higher the contrast ratio, the more visible detail.

MVA and other recent VA technologies offer the highest static contrast ratios of any panel technology. This allows for an outstanding visual experience for movie enthusiasts and other users seeking depth of detail. Higher-end, feature-rich MVA displays offer the consistent, authentic color representation needed by graphic designers and other pro users.

There is another type of panel technology that differs from the monitor types discussed above and that is OLED or “Organic Light Emitting Diode” technology. OLEDs differ from LCDs because they use positively/negatively charged ions to light up every pixel individually, while LCDs use a backlight, which can create an unwanted glow. OLEDs avoid screen glow (and create darker blacks) by not using a backlight. One of the drawbacks of OLED technology is that it is usually pricier than any of the other types of technology explained.

When it comes to choosing the right LCD panel technology, there is no single right answer. Each of the three primary technologies offers distinct strengths and weaknesses. Looking at different features and specs helps you identify which monitor best fits your needs.

With the lowest cost and fastest response times, TN monitors are great for general use and gaming. VA monitor offers a step up for general use. Maxed-out viewing angles and high contrast ratios make VA monitors great for watching movies and image-intensive gaming.

IPS monitors offer the greatest range of color-related features and remain the gold standard for photo editing and color-critical pro uses. Greater availability and lower prices make IPS monitors a great fit for anyone who values outstanding image quality.

LCD or “Liquid Crystal Display” is a type of monitor panel that embraces thin layers of liquid crystals sandwiched between two layers of filters and electrodes.

While CRT monitors used to fire electrons against glass surfaces, LCD monitors operate using backlights and liquid crystals. The LCD panel is a flat sheet of material that contains layers of filters, glass, electrodes, liquid crystals, and a backlight. Polarized light (meaning only half of it shines through) is directed towards a rectangular grid of liquid crystals and beamed through.

Liquid Crystals (LCs) are used because of their unique ability to maintain a parallel shape. Acting as both a solid and liquid, LCs are able to react quickly to changes in light patterns. The optical properties of LCs are activated by electric current, which is used to switch liquid crystals between phases. In turn, each pixel generates an RGB (red, green, blue) color based on the phase it’s in.

Note: When searching for monitors you can be sure to come across the term “LED Panel” at some point or another. An LED panel is an LCD screen with an LED – (Light Emitting Diode) – backlight. LEDs provide a brighter light source while using much less energy. They also have the ability to produce white color, in addition to traditional RGB color, and are the panel type used in HDR monitors.

Early LCD panels used passive-matrix technology and were criticized for blurry imagery. The reason for this is because quick image changes require liquid crystals to change phase quickly and passive matrix technology was limited in terms of how quickly liquid crystals could change phase.

Thanks to active-matrix technology, LCD monitor panels were able to change images very quickly and the technology began being used by newer LCD panels.

Ultimately, budget and feature preferences will determine the best fit for each user. Among the available monitors of each panel type there will also be a range of price points and feature sets. Additionally, overall quality may vary among manufacturers due to factors related to a display’s components, manufacturing, and design.

If you’re interested in learning more about IPS monitors, you can take a look at some of these professional monitors to see if they would be the right fit for you.

Alternatively, if you’re into gaming and are in the market for TN panel these gaming monitor options may be along the lines of what you’re looking for.
