What is multicolored ice?
Multicolored LED is an electronic device involving light emitting diodes of more than one color. Each diode emitting light produces a different color of light by lowering the electricity through the semiconductor and then connects different colors to form the desired final color. Most colors that can be perceived by the human eye can be created in this way. Depending on their design, multicolored LEDs can produce light by combining two, three or four primary colors; These configurations are called dichromatic, trichromatic and tetrachromatic. Multicolored LEDs are used in video display technology.
Like all light emitting diodes, multicolored LED produces light through a phenomenon called electrolyuminescence. When the light emitting diode is on, the electric current begins to flow through the semiconductor. As high -energy electrons flow through the conductive belt of semiconductor material transition to lower energy Materustav und, the energy losing is emitted by JAKO photons. The energy level and the wavelength of these photons depend on the material from which the semiconductor is made, and the color of the resulting light depends on its wavelength.
Multicolored LEDs use the fact that when a person's eye is affected by several waves of light from the same source, it will experience it as the only mixed color, rather than perception of colors that correspond to different wavelengths separately. For example, the human eye perceives light with a wavelength of 620 to 750 nanometers as red and light with a wavelength of 495 to 570 nanometers as green. At the same time, both wavelengths cause the person to see yellow, which is usually produced by light in the range of 570 to 590 nanometers. This allows multicolored LEDs to create a wide range of colors.
The most communicated LED configuration, often called RGB, is trichromatic, with red, green and blue diodes. Are consideredOna for the primary colors of normal human vision, which reflect different wavelengths, which are the most sensitive three different types of cone cells in the human eye. Each pixel display RGB LED contains one diode of each of the three of these colors, which are so small and firmly wrapped together, that the human eye sees them as different sources of light. LEDs in each pixel on and off in different combinations as needed to create all the colors the viewer saw.
Multicolored LED displays are commonly used to create very big video, such as billboards and video screens at sports stadiums. There are smaller television screens suitable for home viewing using multicolored LED technology, but in most respects it lags behind formats such as plasma and liquid crystals. They should not be confused with LED LCD screens LEDjsa often referred to as LED screens or monitors, but in fact these are liquid crystal displays that use LEDs forbacklight.
