1: Can improve the display performance of led display screen: the same number of lamps, the virtual pixel display effect is equivalent to four times of the real pixel display.
2: Can greatly reduce the cost of entire led display: Using virtual pixels, the large led display screen will only use one quarter lamp under the same resolution, and can achieve many of the same visual effect with a lamp in real pixel. Now, the cost of virtual SMD full color big led display is mainly in the lamps.
3: Using the virtual pixel can reduce the fatigue when people watching it , because the more uniform distribution of the luminous point on the big led screen, the light-emitting under same area is more evenly, so the fatigue feeling of people-watching is lower.
