Thanks to Drone Technology, We Have Our Very Own Autobot Transformer

And this particular bot operates under rescue operations.

Not many times do we see pop culture infiltrate real science. We saw it with Star Trek. Then we had such brands like Minority Report bring about the age of the X-BOX and motion sensor technology. Already virtual reality and augmented reality gets us that much closer to what the future has looked like for us in science fiction -- but who would've thought we'd have our very own TRANSFORMER?? Thank drone technology for that one.

Except Instead of Fighting Off Decepticons and Blowing Buildings Up, This Little Bot Simply Saves Lives

And here's how: the University of Zurich and École polytechnique fédérale de Lausanne (EPFL) have been hard at work developing a special type of drone designed for such tasks in first responder missions: a quadcopter designed to actually transform and change shape while mid-flight. Pretty nifty.

The point of this drone is to make it that much easier penetrating hard-to-reach places within disaster sites. The more industrial size drones, while bulky at best but durable at large can't seem to get through a lot of places for good reason. Now instead of equipping such bots with pulse cannons or anything, scientists decided to make it a little more practical and emphasize the one characteristic we enjoy the most about our transformers when we were kids.

Through Machine Learning Sensors and Control Systems, This Transformer Drone Can Morph Into Four Different Shapes and Sizes

Impressive. Most impressive. This makes the drone handy for certain rescue missions requiring location of victims or other materials. The design is such that the drone can remain in standard X-shape formation until facing a narrow passage, which it can then transform into a box-like shape, very much like an H.

If it's facing tighter prospects, it can compress into a smaller O shape. And even better, just in case crevices get more cramped, the drone can morph into a T shape with an on-board camera mounted on the central frame for additional video reach. The real technological science comes in with the fact that the drone operates with high-level machine-learning instruction data operators enter by computer, such as Enter that building or inspect every room and come back. That, however, remains to be seen, but at the current rate of development and with the likes of automation and smart technology continuing to rise like phoenixes from the ashes, there's no doubt....


Drones Will Be at the Forefront of Technology Simply Because They'll Serve Every Aspect of Life

And quite possibly the most important aspect of life: safety and security with the help of an Autobot! Let's roll out.... You can't beat that when it comes to technology and advancement.

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.
