Can play micro film? Professor R & D LED template projection

Scientists in the future, with scientific and technological progress of mankind. According to the Hongkong newspaper LED technology achievements in electrical and Computer Engineering Department of Hongkong professor Liu Jimei's favourite work. In recent years, she has successfully developed a template projection in the LED, 10mm * 15mm can be played on a small area of a single micro film". This technology can be adjusted according to the size and use, is expected to be used for the development of smart glasses, car front glass display and other products.

Template size only 15mm broadcast hd"

LED is a semiconductor electronic component, can be made into different light-emitting products, with high brightness and power saving advantages. With the development of LED technology, the development potential is more and more big. Engaged in LED research for many years, Liu Jimei successfully control the size of the LED template and LED light-emitting display technology, able to film in a single LED template with less than 10mm * 15mm area, resolution up to 1700PPI.

Today's electronic products change rapidly, the main display using liquid crystal display (LCD) technology, but because of the need to use the water in the projection lamp backlight silver, not only expensive, but also high power consumption life of only more than 1 thousand hours, but LED itself can "self-made" light source, no additional heating can greatly reduce consumption, life can be up to tens of thousands of an hour, the energy-saving effect is obvious progress. However, the technology can only do red, blue and green 3 kinds of monochromatic projection, Liu Jimei revealed that the color projection is one of the research directions of her students.

"Wear a helmet without a back mirror"

Liu Jimei said, the display technology can adjust the size of the application level, can make different products according to the needs of the enterprise and the market, for example, with "smart glasses Google Glass" category, "installed in the glasses on the show, and then connected to a video camera. You seem to have more than one eye behind, wearing a helmet does not need to install the rear mirror, and for example, can be installed in front of the car glass, showing speed, maps and other information.

Another "intelligent three in one traffic light" is a viable development of products, she said: "I looked at the traffic lights, why do you want to have 3 lights? 3 kinds of colors can not take turns to open it? "Or" a light circle, the projection of different colors. In addition to color, can also be the word. Red equals Stop (stop) and color blind people can see. With a single block of LED, plus a magnifying glass to do. "
