Supporting stand for display device

A supporting stand for a display device, comprising:

• a base;
• a frame body, connected to the base and used for mounting the display device thereon and rotatable with respect to the base, wherein (i) the frame body has a receiving trough formed within an interior thereof to define a shortest pathway between the base and a predetermined location for mounting the display device, (ii) the frame body includes an upright and a holding unit, (iii) the upright is connected to the base, and (iv) the holding unit is connected to the upright and capable of sliding upward and downward in a channel of the upright;
• an electrical function unit, disposed within the base;
• and
• an electrical connection unit, extending through the receiving trough to provide an electrical connection between the display device and the electrical function unit, wherein (i) the electrical connection unit includes a main cable, (ii) the main cable is electrically connected to the electrical function unit and has a reserve section longitudinally extending to the base and a free section corresponding to the channel of the upright, (iii) the reserve section has a cable length larger than a minimal pathway distance corresponding to the reserve section, (iv) the reserve section of the main cable is in a relaxed state when the frame body is not pivoted to a pivot angle and twists adapted to pivot motion of the frame body, and (v) the free section is forced into bending to be adapted to sliding motion of the holding unit.
