When needs use display device, need display device this moment to possess the big advantage of display size, the folding support frame body 1 of accessible folding drive assembly 2 drive expandes, can control flexible holding surface 101 and OLED flexible screen and expand, and OLED flexible screen expandes the back completely, alright obtain a very big display size. When not needing to use display device, need display device this moment to possess whole size little, occupation space is little and advantages such as security performance height, accessible folding drive assembly 2 drive folding support frame body 1 is folding, can control flexible holding surface 101 and fold together with OLED flexible screen, can reach the effect of being convenient for to deposit this moment, avoid simultaneously because of the potential safety hazard that the collision of carelessness caused.
It should be noted that the innovation point of the present invention lies in the structures of the folding support frame body 1 and the folding driving assembly 2, and the structural arrangement of the folding support frame body 1 and the folding driving assembly 2 takes into account the aspects of the size, space, safety, etc. of the display device, so as to facilitate the daily use of the user, and as for the specific structure and the working principle of the OLED flexible screen, the innovation point of the present invention is not. The OLED technology in the prior art is already mature and applied to the display device, and all OLED flexible screens capable of realizing the display function in the prior art can be used for implementing the technical scheme of the present invention. This is described here.
As shown in fig. 3, 7 and 8, the foldable OLED display device of the present invention preferably further includes a retractable driving assembly 3 in addition to the foldable support frame 1 and the foldable driving assembly 2.

The fan-shaped structures which can be mutually unfolded or mutually folded are formed by the first active support 102, the second active support 103 and the plurality of passive supports 104, so that better folding efficiency can be realized, and the size, the space and the safety of the display device can be better considered.
In the normal working process, the OLED flexible screen needs to be powered on to realize the basic display function, which requires connecting wires to the OLED flexible screen, however, the existence of the wires makes the structure of the display device in the present invention complex, and it is necessary to avoid the wires from interfering with the switching between the unfolded state and the folded state of the folding support frame 1.
Preferably, at least one of the first active support 102, the second active support 103 and the passive support 104 is provided with a hollow structure formed with a wiring cavity for placing an electric wire. At least one of the first active bracket 102, the second active bracket 103 and the passive bracket 104 is set to be a hollow structure, and the structure of the display device can be more reasonable by placing the electric wire through the hollow structure.
As shown in fig. 9, in order to enable the support frame to be more efficiently switched between the unfolded state and the folded state, the passive bracket 104 includes a passive upper bracket 105, a passive lower bracket 106, and an opening and closing rotation shaft.

The display device of the present invention is configured to switch the foldable support frame 1 between the unfolded state and the folded state.
The process that folding support frame body 1 switches from folded condition to expanded condition does: the folding driving assembly 2 drives the first active bracket 102 and the second active bracket 103 to move away from each other, and at this time, the first active bracket 102 and the second active bracket 103 respectively apply pulling forces in opposite directions from two sides of the flexible supporting surface 101, and the pulling forces gradually pull the flexible supporting surface 101 and the OLED flexible screen apart. In this process, the flexible supporting surface 101 will apply a rotational force to the passive upper frame 105, and this rotational force will gradually overcome the magnetic force between the passive upper frame 105 and the passive lower frame 106, so that the passive upper frame 105 rotates forward around the opening/closing rotational axis, and the passive lower frame 106 will not rotate, and only will be fanned out, so that the foldable supporting frame 1 is switched from the folded state to the unfolded state.
The process of the folding support frame body 1 switching from the unfolding state to the folding state is as follows: folding drive assembly 2 drive first initiative support 102 and second initiative support 103 are close to each other, at this moment, first initiative support 102 and second initiative support 103 exert the power of dragging on the both sides of flexible holding surface 101 and disappear gradually, flexible holding surface 101 also disappears to the revolving force of passive upper bracket 105 gradually simultaneously, at this moment, magnetic action between passive upper bracket 105 and the passive lower carriage 106 plays a role, make passive upper bracket 105 round the rotation axis counter-rotation that opens and shuts, passive lower carriage 106 then can not take place the rotation, only can do fan-shaped drawing in, thereby make folding support body 1 switch to fold condition from the state of expanding.
Through the technical scheme, the folding driving component 2 is only needed to drive the first driving support 102 and the second driving support 103 to be away from or close to each other to drive the driven upper support 105 to overcome the magnetic force action and rotate around the opening and closing rotating shaft relative to the driven lower support 106, so that the first driving support 102, the second driving support 103 and the plurality of driven supports 104 can be driven to be unfolded or folded, and the folding driving component has the advantages of simple structure, high reliability and the like.
