Virtual pixel display in each of the LED light tube (virtual pixel) are the same around the light-emitting tube composed of three-color LED pixels, in the same amount of LED light tube, the virtual pixel display than the actual pixel display of three primary colors increased four times the pixels. As a result of pixel multiplexing methods to improve the efficiency of the display show the point, the virtual pixel display when displaying full color images Shandong Which is good, clarity than the same number of points of the actual pixel display increased fourfold virtual pixel display When a monochrome display text mode, because they can not take advantage of the relationship between adjacent pixels display, the display resolution back to its corresponding actual pixel display. For example: 4mm spacing virtual pixel screen Shandong manufacturers offer full color, while displaying the text equivalent of a real 8mm pixel pitch display. A capacitor is a container capable of storing a charge. It is closer to the metal sheet, and then the center compartment with an insulating material and consisting of two sheets of relying. Press the insulation material is not the same, can be made a variety of capacitors. Today, China Sea have to analyze the full-color LED capacitive sense. One, LED full color capacitor analysis: between the two capacitor plates will have a potential difference, when the potential difference between the supply voltage flat charge on the capacitor stopped. If the power cut off at the moment, still insist on charging voltage capacitor. Already charged capacitor, if we use the wire connecting the two plates, as between the electrode plates exists potential difference, the electron will through the wire, back to the positive electrode plate, until the potential difference between the plates is zero. Uncharged capacitor has recovered to a neutral condition, but also no current the wire. Shandong full color full color _ _ Hong Thai manufacturers offer photovoltaic (certified merchants) are provided by Thai-Hong Electronics Co., Ltd. Linyi. Linyi Wang Tai Electronics Co., Ltd.
