1. A display device, comprising:
a case assembly, a first supporting component disposed to be fixed to the case assembly, a second supporting component disposed to be slidable relative to the first supporting component, and a transmission mechanism disposed in the case assembly and connected to the second supporting component; and
a flexible display screen laying on one side of the first supporting component and one side of the second supporting component, a first end of the flexible display screen connected to one end of the second supporting component far away from the first supporting component, and a second end of the flexible display screen connected to the transmission mechanism;
wherein when the first supporting component slides relative to the second supporting component, the two ends of the flexible display screen move, due to effect of the transmission mechanism, with the same distance in the same time,
wherein the case assembly comprises a first case body and a second case body which are disposed opposite to each other, the first case body is fixed to and connected to the first supporting component, and the second case body is fixed to and connected to the second supporting component;
the flexible display screen comprises a first part disposed on a surface of the case assembly and a second part disposed in the case assembly;
the transmission mechanism comprises at least gear set and at least one screw which are positioned on the first case body and a rack set which is positioned on the second case body, the gear set engages with the rack set, and the screw and the gear set rotate coaxially;
when the display device implements a small-screen display, the first part of the flexible display screen is in a display state and the second part of the flexible display screen is in a non-display state; and
when the display device implements a large-screen display, the rack set on the second case body drives, via the gear set, the screw to rotate, so that the second case body moves in a direction far away from the first case body, the second part of the flexible display screen moves from inside of the case assembly to the surface of the case assembly, and the first part and the second part of the flexible display screen are in the display state.
