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.

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 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.

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:

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.

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.

This is what gives e-paper such a natural feel. As a bonus, once the ink is moved to its location, it uses no power to keep it there. This makes these displays naturally low-power to operate.

This article has covered most options available for Arduino displays, though there are definitely more weird and wonderful ways to add feedback to your DIY devices.

2020 Update: NVIDIA and ASUS now has a long-term road map to 1000 Hz displays by the 2030s! Contacts at NVIDIA and vendors has confirmed this article is scientifically accurate.

For this optical effect, view this on LCD instead of CRT or plasma. If using motion blur reduction (e.g. ULMB, BFI, or interpolation), turn that feature off temporarily for this animation demo. Another great TestUFO animation is TestUFO Persistence-of-Vision.

These are two very different pixel response measurements, as seen in the GtG versus MPRT FAQ. There are many 60Hz displays with <1ms GtG (e.g. OLED) but has 16.7ms MPRT (lots of motion blur).

Motion blur on modern digital displays are reduced via strobing or black frame insertion (BFI) to lower persistence. Many LCD gaming monitors use strobe backlights (such as ULMB) that flicker at the same frequency of the refresh rate, in order to reduce motion blur.

Many newer displays, especially OLED displays and modern TN gaming monitors, have the majority of their GtG pixel transitions complete in a tiny fraction of a refresh cycle. This makes GtG an insignificant percentage of MPRT. Such displays exhibit behaviour that closely follows Blur Buster’s Law.

This is the Blur Busters simplification of the MPRT formula found in this scientific paper. We use MPRT100% instead of MPRT90% (in the scientific paper). A120Hz ideal sample-and-hold display has identical motion blur (MPRT100%= 8.333ms) as a 1/120sec photo shutterfor the same physical panning velocity of full frame rate material. We preferMPRT100%at Blur Bustersfor simplicity and to match human-perceived motion blur on fast sample-and-hold displays. This is also easier for blogs to calculate from TestUFO motion tests.

These are additional blur-like artifacts above-and-beyond the guaranteed minimum motion blur mandated by Blur Busters Law. See LCD Motion Artifacts and LCD Overdrive Artifacts for examples.

For low Hz where the Hz is so low, the normally high-frequency stutter no longer blends seamlessly into display motion blur. If you stare at www.testufo.com on a common 60 Hz LCD screen, you will see higher framerates tend to show motion blur while lower framerates tend to stutter (vibrate).

However, once the stutter is high-frequency (e.g. 60fps or 120fps) the 60 or 120 stutters per second vibrates so fast, it just blends into motion blur. The “stutters-blends-to-motion-blur” effect is more easily understood in this variable refresh rate simulation, if viewed on a common LCD (non-strobed):

A huge purpose of variable refresh rate gaming displays (G-SYNC and FreeSync gaming displays) is to eliminate stutters induced from frame rate fluctuations. However, it cannot fully eliminate stutter of ultra-low frame rates (e.g. 15fps or 30fps). Whatever leftover stutter remains, exactly follows Blur Busters Law except that the calculated minimum motion blur (in pixels) is instead the stutter amplitude (in pixels).

In the old days, playing 30 fps games on a 60 Hz CRT created a double image effect. This is still a problem today when playing on strobed displays running any frame rates below strobe rate.

This is why the equivalent refresh rate (e.g. 75 Hz) flickers a lot more on strobed LCD displays than on CRT/plasma displays, because you’re comparing square-waved strobing (e.g. ULMB) versus curved strobing (e.g. CRT).

However, ultra-high frame rates at ultra-high refresh rates (>1000fps at >1000Hz) manages to come very close. This is currently the best way to achieve blurless sample-and-hold with no flicker, no motion blur, and no stroboscopic effects.

Also, real life has no flicker, no strobing and no BFI. Today’s strobe backlight technologies (e.g. ULMB) are a good interim workaround for display motion blur. However, the ultimate displays of the distant future will fully eliminate motion blur without strobing. The only way to do that is ultra-high frame rates & refresh rates.

The limiting factor is human-eye tracking speed on full-FOV retina-resolution displays. As a result, with massive screen 4K TVs, 8K TVs, and virtual reality headsets, higher refresh rates are needed to compensate for degradation of motion resolution via persistence.

Higher resolution displays:The same physical motion speed travels more pixels per second. This creates more pixels of motion blur for the same persistence (MPRT).

Wider field of vision (FOV) displays:The same angular display motion speed (eye tracking speed) stays onscreen longer. This extra time makes display motion blur more easily seen.

This will eventually be necessary for virtual reality, but also useful for huge wall-sized retina displays needing blur-free motion. It will take time, but fortunately, it is closer this century than many think. Experimental 1000 Hz displays now exist.  For example, ViewPixx has a 1440 Hz DLP projector for display research, and there are several other vendors.

It will be challenging for graphics processors to generate the ultra high frame rates necessary for future 1000+ Hz gaming displays of the 2020s and 2030s.
