A supporting structure for a flexible screen , comprising: a first supporting module located below the flexible screen and configured to support the flexible screen , wherein the first supporting module has a first opening; a functional module located below the first opening and used for executing a predetermined function by an external force conducted by the first opening; and a second supporting module located at a position corresponding to the first opening, which forms a deformation protrusion in a direction away from the flexible screen upon an external force acts on the flexible screen , and of which the deformation protrusion is removed when the external force is removed; md wherein the second supporting module comprises: an elastic component used for supporting the flexible screen corresponding to the first opening, which forms a deformation protrusion towards a direction facing away from the flexible screen when an external force acts through the flexible screen , and of which the deformation protrusion is removed when the external force is removed; and a limiting component located at a position corresponding to the first opening, and disposed at a distance to the elastic component to form a gap, which limits the elastic component to be continuously deformed towards the direction facing away from the flexible screen when a length of the protrusion of the elastic component reaches a width of the gap. a first supporting module located below the flexible screen and configured to support the flexible screen , wherein the first supporting module has a first opening; a functional module located below the first opening and used for executing a predetermined function by an external force conducted by the first opening; and a second supporting module located at a position corresponding to the first opening, which forms a deformation protrusion in a direction away from the flexible screen upon an external force acts on the flexible screen , and of which the deformation protrusion is removed when the external force is removed; md wherein the second supporting module comprises: an elastic component used for supporting the flexible screen corresponding to the first opening, which forms a deformation protrusion towards a direction facing away from the flexible screen when an external force acts through the flexible screen , and of which the deformation protrusion is removed when the external force is removed; and a limiting component located at a position corresponding to the first opening, and disposed at a distance to the elastic component to form a gap, which limits the elastic component to be continuously deformed towards the direction facing away from the flexible screen when a length of the protrusion of the elastic component reaches a width of the gap. an elastic component used for supporting the flexible screen corresponding to the first opening, which forms a deformation protrusion towards a direction facing away from the flexible screen when an external force acts through the flexible screen , and of which the deformation protrusion is removed when the external force is removed; and a limiting component located at a position corresponding to the first opening, and disposed at a distance to the elastic component to form a gap, which limits the elastic component to be continuously deformed towards the direction facing away from the flexible screen when a length of the protrusion of the elastic component reaches a width of the gap. <EOS>
