OLED VS LED & LCD

OLED stands for organic light-emitting diode. OLEDs are solid-state devices composed of thin films of organic molecules that create light with the application of electricity. OLEDs can grant brighter, crisper displays on electronic devices and use lower capacity than regular light-emitting diodes (LEDs) or liquid crystal displays (LCDs) used today.

LED stands for light-emitting diode. LEDs are nearly small compared to compact fluorescent and incandescent light bulbs, but they can get hugely bright. Anyhow, LEDs aren’t small suitable to be used as the pixels of a television, they are too huge for that. That’s why LEDs are only used as the backlight for LCD televisions.

LCD stands for liquid-crystal display. LCD displays utilise two sheets of polarising material with a liquid crystal solution between them. An electric current passed through the liquid causes the crystals to adjust so that light cannot pass through them. Each crystal, therefore, is like a shutter, either allowing light to pass through or blocking the light.

Resolution:

Champion - OLED & LCD

OLED and LCD are extensively available in Ultra HD 4K design. In OLED's there is only one model of 1080P but for LCD's there are so many.

Black Level:

Champion - OLED

OLED is the champion here because of its intelligence  to turn off individual pixels completely. It can produce exactly perfect black. The better LCDs have local dimming, where sections of the screen can dim independently of others. This isn't quite as good as per-pixel control because the black parts still aren't absolute but it's better than nothing.

Brightness:

Champion - LCD & LED

When it comes to brightness, LED TVs have a modest asset. LEDs are just really good at getting extremely bright. OLED TVs can get bright, too, but cranking OLED pixels to maximum brightness for extended periods not only reduces that pixel’s lifespan, but the pixel also takes a little while to return to total black.

Contrast Ratio:

Champion - OLED

Contrast ratio is the difference between the brightest and the darkest a TV can be. OLED is the champion here because it can get nearly as bright as LCD, plus it can produce complete black with no blooming. It has the best contrast ratio of any modern display.

Price:

Champion - LED & LCD

At present OLED's are more costlier than the LCD's and LED's. And it take some time for price reduction.

Power Consumption:

Champion - LCD & LED

LCD's and LED's are some what better power consumption than the OLED's. OLED's are also better for power consumption.

Size & Weight:

Champion - OLED

OLED panels are awfully thin and they require no backlight. As such, OLED TV’s tend to be lighter than LED/LCD TVs and considerably thinner. They also require less power, making them more efficient.  

Response Time:

Champion - OLED

While LED/LCD TVs have improved greatly over the past few years, OLED simply blows them out of the water in terms of response time. In fact, OLED currently offers the fastest response time of any TV technology in use today, making it a clear winner in this regard. 

Google Self-Driving Car

Manufacturer - Google
Type - Self-Driving

Google make known a brand new self-driving car prototype on Tuesday. The first company to build a car with no a steering wheel, accelerator or brake pedal.

It is the first genuinely driverless electric car prototype built by Google to test the next stage of its five-year-old self-driving car project. Unlike previous models, these cars won't have human drivers keep track of them at all times. Google said the cars can detect objects up to 200 yards away in all directions and adjust their speed, turns and braking accordingly. The cars' speed for now has been exceed at 25 mph, allowing engineers to minimise the risk of crashes during testing. It operates in and around California, primarily around the Mountain View area where Google has its headquarters. 

It ferries two people from one place to another without any user interaction. The car is summoned by a smartphone for pick up at the user’s location with the destination set. There is no steering wheel or manual control, simply a start button and a big red emergency stop button. In front of the passengers there is a small screen showing the weather, the current speed and a small countdown animation to launch. Once the journey is done, the small screen displays a message to remind you to take your personal belongings – reinforcing that this is not aiming to be a substitute for your personal car at the moment, but more as a replacement for the taxi without the human driver.

It is powered by an electric motor with around a 100 mile range, the car uses a combination of sensors and software to locate itself in the real world combined with highly accurate digital maps. A GPS is used, just like the satellite navigation systems in most cars, to get a rough location of the car, at which point radar, lasers and cameras take over to monitor the world around the car, 360-degrees. The software can recognise objects, people, cars, road marking, signs and traffic lights, obeying the rules of the road and allowing for multiple unpredictable hazards, including cyclists. It can even detect road works and safely navigate around them.

One of the biggest hold-ups to the improvement of the technology onto the open road of Britain, the US, Australia and the rest of the world will be legislation. Google says the cars should be road-ready by early next year, but that testing would take more than two years. At that point the technology will be ready for the next stage, which is likely to be greater pilot testing. Current expectations are that these self-driving cars are at least five years away from being mature enough to create a real, non-prototype product, but it may be far longer until you can buy or hire one for personal use.

VARIOUS PROJECTS ABOUT HUMANOID ROBOT AROUND THE WORLD

A humanoid robot is a robot with its overall presence based on that of the human body, allowing interaction with made-for-human tools or environments. Basically humanoid robots have a torso with a head, two arms and two legs, Even if some forms of humanoid robots may model only part of the body, for example, from the waist up. Some humanoid robots may also have a 'face', with 'eyes' and 'mouth'. Androids are humanoid robots built to theory of art resemble a human.
