20 Claims

1. A display module, comprising a back plate, a light guide plate fixed on the back plate, a rubber frame attached on the back plate and a display panel disposed on the rubber frame, wherein the back plate comprises a bearing surface and a back surface opposite to the bearing surface;

wherein the light guide plate is fixed on the bearing surface, a connecting line between two end portions of the bearing surface forms a first curve, the first curve comprises at least a circular arc segment and a transition curve segment, and the first curve bends in a direction away from the display panel;

wherein the circular arc segment is located at a middle of the first curve, and at least one end of the circular arc segment is provided with the transition curve segment;

wherein the transition curve segment is located at a first position of the bearing surface, the first position being a position of the bearing surface opposite to a second position of the display panel, and the second position being a position where light leaks from the display panel, and a radius of curvature of the transition curve segment gradually increases along a direction close to an end portion of the first curve.
