What is resolution of a digital counter?
That depends. LED (light emitting diode) displays are constructed of diode grids. The entire segment of a number lights up, and each number is composed of seven parts, not counting the decimal light. Otherwise a single 3x5 grid is big enough to display a single digit.

What is light emitting diode for?
To begin with is was to replace incandescent lamps as indicator. But nowadays it is used for myriads of uses from indicator to lamps fixture for your House there are also specialty LEDS like ultraviolet and what notHome LED lighting is a cut above the rest when it comes to energy efficiency. As compared to incandescent lighting, LED lighting wins hands down where energy consumption is concerned. For every 60,000 hours of usage, incandescent lighting uses approximately 3,600 kWh of electricity where LED lighting uses 120 kWh. Bottom line: energy efficiency equals a significant cost savings. LED lighting gives off directional light. Therefore, it is useful as a source of light for reading or spotlighting in the home. Its powerful light output also makes it great for outdoor floodlighting and path illumination. LED bulbs are now available that can replace most halogen or fluorescent light bulbs used in the home.Although LED lighting may not be useful for all home lighting needs, replacing a few bulbs with LED bulbs would have a noticeable affect in the amount of electricity used.LED light displays are already used in signs and videos in many indoor and outdoor sporting events and concerts. LED video displays and signs are often preferred because of their higher brightness, which is critical when people are viewing a sign or video from a long distance. Added advantages of LED video displays are their capacity to incorporate curves and 3-D design. This makes LED video displays technologically superior to currently available large screen displays. Research and developers in the consumer electronics space are eager to take advantage of this overwhelmingly useful technology in future products.Other uses for LED lighting include LED flashlights and key chains, automobile taillights and interior lights, and LED based projection televisions. LED lighting is also being used in the military for LED flashlights that work with night-vision goggles, UV-LED canteen water treatment devices and the sterilization of surgical equipment.ANSWER NOT USED IN A HOME are kidding ? all my lighting inside and out is all LEDS never shut them off what for? saving is in the 98%replaced 3 60 watts lamps with 3 90 watts LED using total 10 wattsWeb Reference:http://www.solrient.comSource:http://www.articlesbase.com/computers-articles/led-lights-the-next-generation-of-home-and-outdoor-lighting-244636.html

Why light emitting diodes are good?
LED (light emitting diode) is an electronic component that generates light from the electrons flowing in one direction through it, in an electron circuit, possibly as part of a circuit board. In a circuit the light emission can be a short as a nanosecond. One or more LED's can be used to make light with a minimum of electricity. Modern applications are wide spread including optical sensor activators, calculator displays and automotive tail lights. LED's have come down in price and can last for tens of thousands of hours so have become an economical replacement for other lights in some applications.
How many times a day does a digital clock display digits whose sum total equals the number of led's used to display them?
A 24 hour clock displays digits whose sum total equals the number of led's used to display them 94 times a day. A 12 hour clock displays them 108 times a day.
How do LED displays work?
Light emitting diodes (LEDs) do not have a filament, like other bulbs do. They emit light by moving electrons inside the bulb. LED displays use up less energy than other displays.
Where is the Hard Drive LED in a computer?
The LED is in the screen where the computer shows the light and displays on the computer when its on.
How to distinguish a LCD monitor from a LED monitor?
LED displays are much brighter than LCD displays. Increase the brightness of both the displays and check the difference, brighter one will be LED. LCD displays always require inverters in its hardware components, where as LED's never uses inverter's. Try to view LED display from different angles , you should be able to see the pictures properly, whereas LCD screens fades the display at different angles.
Where can you get LED scoreboard?
Yeah I do, 1dynamo-led-displays(.)co(.)uk is just one of the many that you can try.
What are the disadvantages of LED displays?
Here i am sharing some of the disadvantage of LED Displays are : LEDs are currently more expensive LED performance largely depends on correctly engineering LEDs must be supplied with the correct voltage and current LED's can shift color due to age and temperature.
Where can I purchase an led display?
