You could change the color of your house with a click. Or how about being able to wear your Facebook page on your back or on your car? LEDs are a very good candidate for making these ideas become reality.
H. J. Round is considered to be the pioneer of the light-emitting diode, (LED) based on his experiment charging electrons to release photons, a phenomenon called electroluminescence. Marconi Labs was able to demonstrate that semiconductors such as gallium would display different colors when charged at various voltages. The first functional LED was created by Oleg Losev, a Russian inventor, in 1927, although it would take several more decades to develop a broad commercial use. On August 8, 1962 the commercialization of LEDs began when two inventors at Texas Instruments filed for patent US3293513 was filed for the first modern LED or infrared light-emitting diode. Texas Instruments then introduced the SNX-100, a commercial LED that, over the next two decades, would come to be used in televisions, household appliances, and digital devices like clocks, watches and calculators. As LED development progressed, their efficiency and reliability increased and so did the range of uses.
HID LED lights have, in recent years, become a common option for both industrial and domestic use in a wide variety of sizes and shapes, both advantages over traditional incandescent lighting. LEDs can be retrofitted to suit any traditional light source and the versatility in light output allows for subtle applications such as mimicry of candlelight. The LED's improved control over the light output also can benefit one's wallet by being more efficient, possibly resulting in a 50% reduction in energy costs. LED light fixtures tend to be favored by the green movement over incandescents because of the former's smaller carbon footprint. LEDs can also be made as small as two millimeters with no adverse effect on the clarity of the light given off. The many benefits of LEDs have led to their ubiquitous presence in our society as witnessed in electronic billboards, stadium scoreboards, airports, transportation, markets and homes.
The next century seems likely to expand the range of possibilities even further. An LED system is currently being developed which is called a flexible organic light emitting diode (FOLED) which makes use of thin (100 nm) flexible plastic films which enables the device to be bent or rolled while in operation. The FOLEDs are already showing promise in revolutionary ways, such as electronic paper and rollable or bendable displays of light and image, perfect for curved surfaces and mobile devices. Other groundbreaking LED research is happening in labs by companies like Philips whose Lumalive products seek to seamlessly integrate light-emitting diodes into textiles, allowing for wearable LEDs and larger decorative room treatments. The ability of an LED to cycle on and off millions of times per second makes it quite suitable for high data bandwidth in optical communication ("LiFi") and has high potential for continued use in the years to come. LEDs may even help humanity to explore space, through light panels used to accelerate vegetable growth in gardens aboard space stations.
Still, here on Earth LEDs continue to evolve in amazing ways. Large corporations are putting money into LED research here and now, such as 3M's " Virtual LED," which maximizes the light from one LED to fill a large space.Osram's flexible waterproof LED mounts have already given architects and engineers the ability to bend light displays.Laface and Mcgovern, Incorporated constructs a similar product, a flexible LED strip coated with a polycarbonate resin which is said to provide improved clarity and control over the light emitted.

The modern day LED is already a wondrous invention and sure to appear and be used even more in the future, just don't try reading the car of the guy next to you once traffic starts moving again.
