        For a pixel unit of digital images, like photography picture, digital imaging also has dense gradation continuity, if the image is magnified several times, will find these continuous tone is actually composed of many small points with similar color composition, the square is the smallest unit that form the image pixel minimum graphics the unit can display on the screen is usually a single pixel unit "is used to calculate the digital image, like photography picture, digital imaging also has dense gradation continuity, if the image is magnified several times, will find these continuous tone is actually composed of many small points with similar color composition, the smallest unit" these small points form the image pixel is the smallest unit in the graphical display on the screen is usually dyed a single point.

         According to the principle of color, that the red green blue (R (G B (known as the three primary colors. These three colors can be combined to get any color from black to white. LED display screen classification, a monochrome display, color display, color display. Color is relatively simple, only need to select any three colors in a color monochrome display can be realized. In practical applications, the choice of red LED lights more. In this case, a red LED light is a pixel.

        Two color display and monochrome display similar, as long as the arbitrary choice of three colors in two colors to achieve double color. In practical applications, multi selection of red and green. When the red and green at the same time, can realize the yellow. Therefore, the dual color display screen can be achieved red, green, yellow 3 colors.

        Full color LED display because to show various colors. Therefore, it is necessary to performance from black to white between different colors. Therefore, the color LED display red, green and blue to 3 lights together constitute a pixel to show various colors. Full color LED display, and divided into real and virtual pixel display pixel display. Because of the use of the display technology is not the same, so the way the pixel point is not the same.

       Virtual display using virtual pixel technology, that is, the use of LED multiplexing technology, the same LED light-emitting tube, the use of adjacent LED light-emitting tube for the 4 combination (bottom, bottom, left and right combination).

       To the indoor display screen, mainly is the unit board. Cell board is composed of lattice modules in the lattice module has been 1 red, 1 green, 1 blue LED light package together to form a pixel point.
