Product Description
Do you know led advertising sign? Pixel pitch P We often see or hear people saying P10 LED display, or P5, P16, the P is to point to any two adjacent pixels to the center of the physical distance, another way to from here as pixels shine diameter lower than; The smaller the distance between points at close range when the display screen ornamental images is exquisite degree more good; The greater the distance between points, best observation distance increases, LED the luminous intensity of also need to appropriate heighten. RGB English red, green, blue (namely red, green, blue) is the abbreviation of, in the LED display industry, usually said R red, green, blue G B 3 kinds of color. LED light emitting diode is the abbreviation of, everybody else leds. LED diode is the Ⅲ by elements spectrum-Ⅳ family compounds, such as GaAs (gallium arsenide), GaP (phosphating gallium), GaAsP (p gallium arsenide) made of semiconductor, its core is the PN junction. So it is generally P-N "of I-N characteristics, namely is the guide, reverse globe, breakdown characteristic. In addition, with a certain conditions, it also has the characteristics of light. The positive voltage and electronically by N area into P area, hole by P area into N area. Into each other area of minority carriers (ShaoZi) with majority carrier (many children) composite and shine. Light is that in P happened in the area, then into electronic and valence band hole direct compound and shine, or be luminous center after capture, again with hole composite luminescence. In addition to this luminous compound outside, still some electrons are not shine center (the center between the conduction band, interface among with near) capture and then and hole compound, every time release energy is not big, can't form visible light. The shine of composite relative amount in the glow of the greater the share of the compound, the higher the luminous efficiency. Resolution Refers to display terminals in horizontal and vertical direction on the picture processing and display ability, usually with horizontal and vertical direction XiangSuShu effective of the product of the XiangSuShu effective, that is to say the total number of pixels effect. Gray level No matter use LED production monochrome, double color or a full-color LED display to a display image of the pixels each LED to the luminous intensity must can adjust and the control of delicate degree of gray level is display screen. Gray level, the high, show the picture more exquisite, colour is also more rich, the corresponding display and control system is also more complicated. General level 256 shades of the image, color transition already was very gentle, and 16/32 / level 64 shades of color images, color transition boundary is very clear. So, color LED the current are required to make class 256/16384 gray, the gray level of the realization of the combination of colors and color excessive is more than the human eye to color resolution ability. Virtual pixel technology (also called LED multiplexing technique or pixel decomposition technique) Will a pixel split into some independent of each other LED units. Each LED unit time multiplex way to reproduce some of the adjacent pixels corresponding gezer information. Commonly used to form for 2 R + 1 G + 1 B four pixel type dynamic pixels as an example, a pixel resolution for four independent of each other LED units. Each LED unit time multiplex way represent four adjacent pixels corresponding gezer information, usually, each space between each other for LED evenly distributed. Good (with four pixel type dynamic pixel technology as an example) virtual pixels (physical, but in fact there can realize the pixel) density increased to 4 times; Effective visual pixel density can improve the largest 4 times. Shortage this technology with LED space uniformly distributed, therefore composition of each pixel LED the interval between present biggest discrete conditions. And LED concentration distribution way in, pixel color performance of mix a little almost; In the physical brightness the same situation of visual display screen brightness is weak. Because every one of the time multiplex LED way, circulation scanning pixels adjacent four information, so that the text in single stroke will have the unclear writing phenomenon. Virtual pixel technology used in viewing distance than physical pixel display 2048 times the distance P.
