IBM Just Filed a New Patent for a Revolutionary Drone, and It's Quite the Wake-Up Call

Let's just say you'll get a caffeine jolt from it!

Quite the jolt, actually, but we're honestly not surprised. Drone technology currently sits at the forefront of techno-trend for obvious reason. The concept of drones applies to many different verticals, and now it seems IBM has jumped on that bandwagon in a big way -- by filing a patent for a new type of drone. Can you guess what it is?

Try Coffee Delivery -- That's Right, a Delivery Drone That Transports Coffee to You

#

We call that interesting -- so interesting as to the aggressive trademarking of a drone simply designed to deliver some Joe on the fly. Literally. Interestingly enough, the patent describes a type of drone that can detect actual lagging -- tiredness, if you will! You heard correctly -- a drone that can sense when you need some caffeine in your system.

In other words, fear not -- you won't need to live right by a Starbucks. If you're suffering from sleepiness, this is a drone that can actually patrol the skies, scanning the many below who may need a cappuccino or two. Now that's technology innovation at its best.

IBM imagines this as an unmanned copter, scanning through sensors connected to a UAV. With predetermined cognitive states and sensor data, you get information that could easily result in machine learning algorithms designed to launch tasks for coffee deliveries.

Additionally the drone will be designed to monitor blood pressure, pupil dilation and all sorts of facial expression via camera mount. Ways for people to signal would be similar as motioning for a taxi. Through sensors designed to spot those signals, a simple hand motion could then result in the drone flying right in with a cappuccino. Hypotheticals, of course, of delivery details include the simple pouring of coffee into a mug, or perhaps a more full-service approach of sealed bags of coffee grounds. The sky's the limit here.

You Wouldn't Believe That IBM Is Even Considering Another Kind of Beverage....

Alcohol. Beer. Maybe even a cocktail or two.

You'd think IBM is pretty nuts, but that's ambitious and rather realistic in a way. Think about it. A drone that can read biometrics in reverse, detecting unsteadiness and slurred speech as a way to tell that a customer is drunk enough to be cut off completely. This, however, doesn't suggest that the patent will mean IBM will be developing such a drone, but it's not beyond the realm of possibility. So in other words, we may just have our very own drone bartender in the sky one day.

Is an OLED screen worth it?

OLED monitors tend to have faster pixel response times and better contrast ratios, although their very high prices make them much less accessible than ordinary LCD monitors.

As such, we do not yet recommend purchasing an OLED monitor, as a high-quality LCD monitor will be fully capable of providing a satisfying experience at much lower prices.

OLED technology has been around for a while, but it's only just starting to break into the monitor and TV market. Even so, screens using this technology remain few and more importantly - they are expensive.

So what is the reason for the exorbitant price of most OLED monitors, and what are their advantages and disadvantages compared to ordinary LCD monitors?

OLED vs LCD display technology

Whenever you see a screen marketed as an “LED” monitor, it usually means an LED LCD screen. To be more specific, it uses LED backlighting, but it's the LCD technology that does most of the work.

On the other hand,

OLED technology has no active backlight. Instead, each pixel is independently lit and works as its own light source.

This has many implications for the quality and performance of a screen.

Contraste OLED vs LCD

OLED screens have been present in smartphones for a long time.

In fact, Samsung’s first Galaxy S phone used OLED, although the technology was much less refined at the time.

For years, smartphone users have debated the merits of the LCD vs OLED display, and everything that can be said about it also applies to larger displays.

OLED displays can achieve much higher contrast because they can display true black by simply turning off pixels.

On the other hand, any screen with active backlight cannot completely block the light, so that black is displayed in dark gray. Certainly, some panels (like VA) are better for displaying blacks, but they still don't match the OLEDs in this department.

Speaking of backlighting, there is a common problem that LED LCD screens to call bleeding from the backlight. When this happens, some of the light “bleeds” on the screen, leading to inconsistent blacks.

This can happen either as irregular white spots (so-called "clouds") or as visibly brighter areas at the corners or along the edges of the screen.

Since OLED displays do not use active backlighting, they do not have this problem. Overall, OLED wins hands down in this regard.

Observation angles

A viewing angle determines the width of the angle from which the display can be viewed without any visible loss of image quality. As you move outside the specified viewing angle of the screen, the color distortion begins to become visible.

OLED screens have excellent viewing angles, mainly because there is very little space behind the screen for the light to diffract.

The situation with LCD screens is a little more complicated since the viewing angles depend mainly on the type of panel used. So, for example, a good IPS panel can easily match the viewing angles of an OLED, while a TN panel can't even get close to it.

OLED color reproduction

The most remarkable and often the most marketable quality of a screen is its ability to dazzle the viewer with its vibrant and realistic color reproduction.

In most cases, OLED and LCD screens are on flat ground in this regard.

However, as with viewing angles, the color accuracy of an LCD screen depends mainly on the panel used. IPS and VA panels tend to have excellent color reproduction, while colors produced by TN panels tend to look quite washed out.

HDR is a display technology with a simple goal: to make the displayed image appear as close to reality as possible. This is achieved by creating a more realistic contrast and producing a more intense light.

Now, as we have already determined, OLED definitely has the advantage in terms of contrast. However, LCD screens can still hold on by having a more powerful backlight. Both technologies are quite capable of producing good HDR, so, once again, we have a tie.

Performance - Refresh rate and response time

Well, first of all, you'll be happy to know that modern OLED displays are quite capable of achieving such high refresh rates. In addition, their theoretical limits are very high, so that they could reach even higher refresh rates one day, but this is not necessary.

As for response times, they literally overwrite LCD screens as they can have response times as low as 0.1ms. During this time, the fastest TN panels cannot go down to 1ms.

We are inclined to give the OLED focus, mainly because of the much faster response times.

OLED vs LCD screen price

And now the big question - is an OLED screen worth it?

As we said before, OLED displays are very expensive and will remain so for the foreseeable future. More importantly, it is not only that they are expensive, but that they are of questionable value. Their only concrete and the tangible advantage is their superior contrast.

That said, we will have to give this round to the LCD screens. A good LCD monitor will be more than capable of equaling an OLED in terms of visual quality and performance.

Conclusion Should we buy an OLED screen?

Overall, we do not yet recommend purchasing an OLED display.

As is often the case with (relatively) new technologies, it takes time to perfect them and to truly penetrate the market. Do you remember when the first 4K TVs started to roll out and cost thousands of euros?

Now you can get a 4K TV for less than € 300. Not really a good 4K TV, but a 4K all the same.

It will be the same with OLED in the years to come. Manufacturing processes will improve, the technology itself will improve, and prices will eventually fall to more affordable three-digit numbers.
