Light-emitting diode (LED) display panels have received more attention
recently. These panels usually are placed in public places such as streets,
squares, highways, and stadiums for live broadcasting of sporting events, TV
programs, advertisements, and movie clips. An important characteristic of
these panels is the minimum distance to see contiguous images on the panel
with desirable quality which is referred to as the minimal viewing distance
and is represented by <i>d<sub>V</sub></i>. The minimal viewing distance depends on the pixel shape and
pitch of the panel.In this paper, we study the relationship between the minimal viewing
distance and the pixel shape and position and then provide a method to
reduce this distance. This method can be used to manufacture panels with
particular diagonal and distance of pixels for a required <i>d<sub>V</sub></i> for a specific location.
