At least a portion of the support structure is fixedly connected to the flexible display panel so that when the flexible display panel is reciprocated in a first direction and a second direction, the support structure is switchable between a first state and a second state. The support structure has a smaller support surface in the first state than in the second state, and the first direction is opposite to the second direction.",
  "claims": [
    "1. A support assembly for supporting a flexible display panel, comprising: a support structure configured to support the flexible display panel; and a driving structure configured to drive the support structure against the flexible display panel, wherein at least a portion of the support structure is fixedly connected to the flexible display panel so that when the flexible display panel is reciprocated in a first direction and a second direction, the support structure is switchable between a first state and a second state, wherein the support structure has a smaller support surface in the first state than in the second state, and the first direction is opposite to the second direction, wherein the support structure comprises a plurality of support plates, the support structure changes from a stacked state to a spliced state when the flexible display panel is moved in the first direction, and changes from the spliced state to the stacked state when the flexible display panel is moved in the second direction, wherein in the stacked state, the plurality of support plates are stacked on top of each other, and in the spliced state, the plurality of support plates are sequentially spliced into a flat plate shape, wherein the driving structure comprises: a bearing plate configured to bear the plurality of support plates in the stacked state; and an elastic member connected to the bearing plate and configured to apply a force toward the flexible display panel on the bearing plate so that the support plates on the bearing plate are driven to abut against the flexible display panel.",
    "2. The support assembly according to claim 1, wherein a first support plate of the plurality of support plates is fixedly connected to the flexible display panel.",
    "3. The support assembly according to claim 1, wherein each of the plurality of support plates comprises: a connecting assembly configured to connect a support plate with an adjacent support plate to form the support structure in the spliced state.",
    "4. The support assembly according to claim 3, wherein the support assembly further comprises: an elastic toggler configured to connect the support plates with each other through the connecting assembly so that the support structure is in the spliced state.",
    "5. The support assembly according to claim 4, wherein the connecting assembly comprises: a first limiting slot located on a first surface of the support plate and opened toward a first edge of the support plate, the first surface being a surface opposite to the support surface of the support plate; a second limiting slot located on the first surface of the support plate and opened toward a second edge opposite to the first edge of the support plate, wherein in the spliced state, the first limiting slot and the second limiting slot of adjacent support plates form a cavity; a limiting slider comprising a first part, a second part and a protruding part connecting the first part and the second part, wherein the first part is located in the first limiting slot and has a shape fitted with the first limiting slot, the second part has a shape fitted with the second limiting slot, the limiting slider is movable in the cavity, and in the spliced state, the first part of the limiting slider is located in the first limiting slot, the second part is located in the second limiting slot of the adjacent support plate, so that the two adjacent support plates are spliced together, and in the stacked state, the limiting slider is arranged only in the first limiting slot; wherein the elastic toggler changes a position of the limiting slider relative to the first limiting slot by toggling the protruding part of the limiting slider.",
    "6. The support assembly according to claim 5, wherein the first edge of the support plate forms an acute angle with the support surface of the support plate, and the second edge of the support plate forms an acute angle with the first surface of the support plate.",
    "7. The support assembly according to claim 6, wherein the bearing surface of the bearing plate forms an acute angle with the first direction.",
    "8. The support assembly according to claim 1, wherein the support assembly further comprises: a first receiving structure configured to receive the plurality of support plates of the support structure in the stacked state, wherein the first receiving structure comprises a bottom wall and a sidewall connected with the bottom wall, the elastic member is fixed on the bottom wall, the bearing plate is located in the first receiving structure, the bearing plate is movable within the first receiving structure under an action of the elastic member, and the first receiving structure limits movement of the bearing plate and the support structure in other directions than a direction perpendicular to the bottom wall.",
    "9. The support assembly according to claim 8, wherein the elastic toggler is secured to the sidewall of the first receiving structure so that when the limiting slider passes through the elastic toggler, the elastic toggler generates a driving force on the protruding part of the limiting slider to move the limiting slider relative to the first limiting slot.",
    "10. The support assembly according to claim 1, wherein at least one edge of each of the plurality of support plates has a wedge-shaped configuration.",
    "11. The support assembly according to claim 1, wherein the elastic member is a spring.",
    "12. A storage and deployment apparatus for a flexible display panel, comprising: a second receiving structure configured to receive the flexible display panel in a rolled state; and the support assembly according to claim 1.",
    "13. The storage and deployment apparatus according to claim 12, further comprising: a rotation shaft located in the second receiving structure, the flexible display panel being wound around an outer peripheral surface of the rotation shaft, wherein rotation of the rotation shaft drives the flexible display panel and the support structure of the support assembly to move in a first direction or a second direction."
