Spherical screen module unit and spherical screen structure assembled by the same

A spherical screen structure, comprising:

• a plurality of first spherical screen module units, wherein each of the first spherical screen module units forms a first sector structure, the first sector structures are arranged around a center of a circle and connected to each other, each of the first sector structures has a first inner arc edge and a first outer arc edge, which are formed on opposite sides of a first sector base, wherein an arc length of the first outer arc edge is greater than an arc length of the first inner arc edge, when the first spherical screen module units are provided on a spherical screen assembling surface, a first height is between an upper surface of the first inner arc edge and the spherical screen assembling surface, and a second height is between an upper surface of the first outer arc edge and the spherical screen assembling surface, wherein the second height is greater than the first height;
• and
• a plurality of second spherical screen module units, wherein each of the second spherical screen module units forms a second sector structure, the second sector structures are arranged around the center of the circle and connected to each other, each of the second sector structures has a second inner arc edge and a second outer arc edge, which are formed on opposite sides of a second sector base, wherein an arc length of the second outer arc edge is greater than an arc length of the second inner arc edge, each of the second spherical screen module units is connected to the corresponding first spherical screen module unit, and the second inner arc edge of each of the second sector structures is connected to the corresponding first outer arc edge of the first sector structure.
• wherein when the second spherical screen module units are arranged on the spherical screen assembling surface, a third height is between an upper surface of the second outer arc edge and the spherical screen assembling surface, wherein the third height is greater than the first height.
