Abstract
A spherical screen module unit includes a sector base including a sector carrier having an inner and outer arc edges; arc length of the outer arc edge is greater than that of the inner arc edge. An inner ramp frame is on the sector carrier and closer to the inner arc edge; an outer ramp frame is on the sector carrier and closer to the outer arc edge. When the spherical screen module unit is on a spherical screen assembling surface, minimum distance between the inner ramp frame upper surface and the spherical screen assembling surface is first height; maximum distance between the outer ramp frame upper surface and the spherical screen assembling surface is second height which is greater than the first height. A spherical screen structure including spherical screen module unit facilitates the module unit disassembly for repair, maintenance, or angle adjustment, and increases applicability in different environments.
