When it is desired to fold the foldable screen 10, the support member 200 can be rotated about the rotating shaft member 100 to a folded state as shown in fig. 10, so that the flexible display 300 is folded in half, and the display area of the flexible display 300 in the same plane is smaller than that in the unfolded state.
Referring to fig. 2, the support assembly 200 includes a first support plate 210 and a second support plate 220. The first support plate 210 and the second support plate 220 are connected to the rotation shaft assembly 100, wherein the first support plate 210 may be connected to one side of the rotation shaft assembly 100, and the second support plate 220 may be connected to the other side of the rotation shaft assembly 100. The first and second support plates 210 and 220 can rotate about the rotation shaft assembly 100 so that the foldable screen 10 can be switched between the folded state and the unfolded state. The first support plate 210 and the second support plate 220 both have a bearing surface 211(221), the second support plate 220 also has a mounting surface 222 arranged opposite to the bearing surface 221, the bearing surface 211(221) is a surface providing a supporting force for the flexible display screen 300, and in the unfolded state, the bearing surfaces 211(221) of the first support plate 210 and the second support plate 220 are flush with the upper tangent plane of the rotating shaft assembly 100 for better bearing the flexible display screen 300, so that the flexible display screen 300 can present display contents in a relatively flat state in the unfolded state.
The flexible display panel 300 may adopt an OLED (Organic Light-Emitting display) panel for displaying information, and the OLED panel may be an AMOLED (Active Matrix Organic Light-Emitting Diode) screen or a Super AMOLED (Super Active Matrix Organic Light-Emitting Diode) screen or a Super AMOLED Plus (Super Active Matrix Organic Light-Emitting Diode Plus) screen.
Referring to fig. 2, the flexible display screen 300 includes a display area 310 and a frame area 320, one end of the display area 310 is fixed on the first support plate 210, the frame area 320 is connected to the other end of the display area 310, and the frame area 320 of the flexible display screen 300 can be slidably connected to the second support plate 220. The flexible display screen 300 is laid on the rotating shaft assembly 100, the first support plate 210 and the second support plate 220, and the rotating shaft assembly 100, the first support plate 210 and the second support plate 220 play a bearing role for the display area 310. The frame area 320 of the flexible display screen 300 slides relative to the second support plate 220, so that the flexible display screen 300 can be bent and flattened, and the foldable screen 10 can be switched between the unfolded state and the folded state.

The cover 400 can be folded or unfolded simultaneously with the flexible display 300 to accommodate switching of the foldable screen 10 between the unfolded state and the folded state. The cover plate 400 can protect the flexible display screen 300, and meanwhile, due to the fact that the cover plate 400 is attached to the flexible display screen 300, the flexible display screen 300 is prevented from protruding towards the cover plate 400, and the flexible display screen 300 is prevented from being wrinkled to improve the flatness of the flexible display screen 300.
Referring to fig. 1-4, and 9, in some embodiments, the cover plate 400 includes a first glass plate 410, a second glass plate 420, and an intermediate flexible plate 430. The first glass plate 410 and the second glass plate 420 have high rigidity and strong resistance to bending deformation, and when the foldable screen 10 is switched between the unfolded state and the folded state, the first glass plate 410 and the second glass plate 420 are both flat and do not bend. Middle elastic plate 430 can be the silica gel board, and middle elastic plate 430 adopts the silica gel material to make promptly, and the silica gel board has fine elasticity and can follow flexible display screen 300 and produce and buckle, and when bending moment did not exist, the silica gel board can resume to original exhibition flat state by the state of buckling. The first glass plate 410 corresponds to the first support plate 210, the second glass plate 420 corresponds to the second support plate 220, and the intermediate elastic plate 430 corresponds to the rotation shaft assembly 100. The frame area 320 of the flexible display 300 is located on a side (not shown) of the second supporting plate 220 where the supporting surface 221 is located, and meanwhile, the frame area 320 is slidably connected to the supporting surface 221. When the foldable screen 10 is converted from the unfolded state to the folded state, the frame region 320 slides relative to the supporting surface 221 near the rotating shaft assembly 100 to adapt to the bending of the middle elastic plate 430; when the foldable screen 10 is transformed from the folded state to the unfolded state, the frame region 320 slides away from the pivot assembly 100 relative to the bearing surface 221 to accommodate the flattening of the middle elastic plate 430.
For the display area 310 corresponding to the first support plate 210, when the folded state and the unfolded state are switched, the first support plate 210 and the first glass plate 410 are not bent, the bearing surface 221 of the first support plate 210 plays a supporting role, and the part of the display area 310 cannot be recessed towards the first support plate 210; meanwhile, the first glass plate 410 acts as a ballast to the display area, and the part of the display area 310 cannot protrude towards the first glass plate 410, so that the part of the display area 310 can be effectively prevented from forming wrinkles through the clamping action of the first support plate 210 and the first glass plate 410, and the flatness of the display area can be further ensured. Similarly, when the display area 310 corresponding to the second supporting plate 220 is switched between the folded state and the unfolded state, the second supporting plate 220 and the second glass plate 420 are not bent, and the flatness of the portion of the display area 310 can be ensured by the sandwiching action between the second supporting plate 220 and the second glass plate 420. For the display area 310 corresponding to the rotating shaft assembly 100, in the unfolded state, the surface of the rotating shaft assembly 100 supporting the display area is a plane, the middle elastic plate 430 is a flat plate, and the part of the display area 310 does not generate uneven wrinkles through the clamping effect of the two; in the folded state, the surface of the rotating shaft assembly 100 supporting the rotating shaft assembly is curved, the middle elastic plate 430 is bent to form a bent plate, and the part of the display area 310 is still sandwiched between the bent rotating shaft assembly 100 and the bent middle transparent plate, and the flatness of the part of the display area can be maintained. The first glass plate 410, the second glass plate 420 and the middle elastic plate 430 have good impact strength, so that the flexible display screen 300 is prevented from being damaged and sunken due to external force impact, and the flexible display screen 300 is well protected.
In some embodiments, the frame region 320 of the flexible display screen 300 is bent to the mounting surface 222 of the second supporting plate 220 relative to the display region 310 and is slidably connected to the mounting surface 222. The cover plate 400 further includes an edge elastic plate 440, and the edge elastic plate 440 may also be made of a silicone material, i.e., the edge elastic plate 440 is a silicone plate. The edge elastic plate 440 is connected to the second glass plate 420, the edge elastic plate 440 includes a sliding portion 441 disposed away from the second glass plate 420, the sliding portion 441 is bent to a side of the mounting surface 222 of the second supporting plate 220 relative to other portions of the edge elastic plate 440, the sliding portion 441 is attached to the frame region 320 of the flexible display screen 300 and slides along with the frame region 320 relative to the mounting surface 222, and other portions of the edge elastic plate 440 except for the sliding portion 441 are attached to the display region 310. When the foldable screen 10 is converted from the unfolded state to the folded state, the frame region 320 and the sliding portion 441 simultaneously slide relative to the mounting surface 222 away from the rotating shaft assembly 100 to accommodate the bending of the middle elastic plate 430; when the foldable screen 10 is converted from the folded state to the unfolded state, the frame region 320 and the sliding portion 441 simultaneously slide relative to the mounting surface 222 near the hinge assembly 100 to accommodate the flattening of the middle elastic plate 430. The edge elastic plate 440 can be adapted to the bending of the flexible display panel 300, and the flatness can be ensured by the clamping of the edge elastic plate 440 and the second supporting plate 220. Since the frame region 320 and the sliding portion 441 are bent to the side of the mounting surface 222, when the foldable screen 10 is mounted in the electronic device 20, the entire size and the unfolded area of the electronic device 20 can be reduced with the area of the display region 310 constant, thereby improving the screen occupation ratio of the electronic device 20.
