  • Patent number: 11092525
    Abstract: A method and device for performing a bending test on a display panel are disclosed. The method includes the steps of: providing a fixing member, a pressure exerting member and a driving device, and forming a space in the fixing member; fixing the display panel vertically onto the fixing member, wherein the display panel matches with the space to provide a corresponding space for deformation of the display panel; and driving the pressure exerting member to move in a direction perpendicular to the display panel to exert a pressure onto the display panel. If the pressure exerted onto the display panel is equal to a predetermined pressure for a predetermined time, the driving device controls the pressure exerting member to stop exerting the pressure onto the display panel. The predetermined pressure is a pressure required to drive the display panel to deform and reach a predetermined curvature.
