Surface Conduction Electron Emitter Display

The team included researchers from the University of California Santa Barbara (UCSB), UCLA, and UC Riverside.

Here are some videos:

Benefits

The Surface Conduction Electron Emitter display provides a very fast response time while consuming relatively little power. It can produce high-resolution images as well as provide touch screens. These displays work by using an array of tiny nanoscale emitters called surface conduction electron sources (SCEs) to generate electrons in the gas phase.

A thin insulating layer separates the emitter from a metal gate electrode, and this allows electrons to pass through when the voltage is applied across the two electrodes. The electrons collide with molecules of phosphor coating on the back side of the screen, releasing photons that create the image. Check this out Phone Repair Shops.

Drawbacks

One disadvantage of the LCD display is that it can only produce black-and-white images. Color displays require additional electronics, which adds to the cost. In addition, the image quality is not as good as other types of displays.

Another potential drawback of LCD technology is the poor viewing angle. That means when the user turns his head, the screen appears washed out. This can make a laptop hard to use for tasks such as watching movies.

Listicle

1. What is an SCE? In short, it’s the tiny dots that allow a liquid crystal display (LCD) screen to work properly.

2. How does it work? An SCE uses the same principle as light-emitting diodes (LED). They use electricity to push electrons across a thin layer of material called the cathode and then back again to create the image.

3. Why would we want to have them? Because they’re better at creating images, but also because they require less power.

4. Where did it come from? From Japan.

5. Will there be more coming? Yes, in fact, it will soon become even thinner and brighter.

6. Are they a threat? Not really.

7. Who makes it? Sony & Panasonic.

8. Have you seen one? No, not yet.

9. Do you know how to make one? Yep!

10. Can you get me some, please? Sure thing – just leave a comment.

FAQ

1. Can I see this at a store near me? This is not available for purchase yet. Click for more info

2. Will there be different sizes of these displays? There will be several sizes, but they won’t all be made by the same company. It’s up to the manufacturers to decide what size display will work best with their products.

3. What does the word “electrode” mean? An electrode is a part that makes contact with an electron emitter. In SCEED, the electrodes are made out of plastic. They look like little rods.

4. How much power can it use? The maximum amount of current is 100 mA (milliamps).

5. Is it safe for my kids? Yes, it is very safe.

6. What will I need to operate one of these displays? You will just have to plug it into a wall outlet.

7. Where do I find these displays? These types of displays aren’t sold in stores yet, so you’ll probably need to order online.

8. What’s the price tag on these new displays? At the time that I wrote this, the prices ranged from $40 to $150.

The present invention relates to a novel and useful fuel delivery system for internal combustion engines.

In conventional carburetor-type engines, the air is drawn through a throttle valve which controls the flow of gasoline or other fuel being mixed with the incoming air.

This mixture of gasoline is then fed to cylinders containing pistons, thus allowing the piston within each cylinder to be propelled back and forth over a distance, thereby producing mechanical energy.

Conventional carburetion systems typically utilize either float-controlled valves or vacuum-controlled valves. Float-controlled valves require the addition of an extra component to control the introduction of fuel, namely, the use of floats.
