Comprehensive analysis of LED pixel display

“Pixel” is a unit used to calculate the digital image,just like the picture of photography, digital imaging has dense gradation continuity, if we put the image enlarged several times, will find these continuous tone is composed of many small points with similar color composition, the smallest unit of  the small image is formed pixel .According to the theory of color, we know that the red (R), green (G), blue (B) is regarded as one of the three primary colors. These three colors can be combined to obtain any color from black to white. In the display of the LED classification, a monochrome display, color display. Color is relatively simple, only need to select any  a color in three primary colors to achieve  LED pixel module display.http://www.ledlightmake.com/bmz_cache/Hot%20Selling%20WS2801%20LED%20Pixels5.jpg
 In practical application, select the red LED lights more. In this case, a red LED lamp is one pixel. As shown in figure 1.

Full color LED display to show a variety of colors, so it can show different color from black to white,
so the full-color display  need to three primary color can show a variety of colors for customer.    and is divided into real and virtual pixel display pixel display.  because of the display technology is not the same Both, so the pixels which are not the same. As shown in Figure 2
