Slide roll apparatus and display apparatus

A display apparatus, comprising a sliding and rolling device,

• wherein the sliding and rolling device is configured for assisting a flexible display module in rolling and unrolling by sliding, and the flexible display module comprises a first side edge and a second side edge arranged opposite to each other in an X direction;
• wherein the sliding and rolling device comprises:
• a fixed housing, comprising a mounting structure, wherein the mounting structure is at least configured for fixing the first side edge of the flexible display module;
• a movable housing, configured to reciprocate in the X direction relative to the fixed housing;
• a sliding track, arranged on at least one side of the movable housing in a Y direction, wherein the Y direction is perpendicular to the X direction, and a plane formed by the X direction and the Y direction is parallel to the flexible display module;
• a support structure, arranged on a side of the movable housing, wherein the support structure is slidably arranged in the sliding track along an arc path, a side of the support structure away from the movable housing is configured for supporting the flexible display module and is relatively fixed to at least the second side edge of the flexible display module, and the flexible display module is configured to slide along the X direction with the support structure;
• an external support structure, contacting the movable housing along the Y direction, wherein when the flexible display module unrolls, the external support structure abuts against both the support structure and the movable housing to provide a supporting force along the Y direction to the support structure, so that a distance between the support structure and the sliding track in the Y direction is reduced;
• wherein the display apparatus further comprises the flexible display module;
• wherein the flexible display module is arranged on a side of the support structure and the fixed housing in the sliding and rolling device.
