摘要： The present disclosure provides a light-emitting structure, a display panel, a display device, and a control method for a display panel, so as to solve the problem that the user's eyes cannot clearly see the image displayed by the display panel due to ambient light. The light-emitting structure includes a light-emitting unit and a variable reflectivity unit. The light-emitting unit includes a first electrode, a second electrode and a light-emitting layer in between. The first electrode is a transparent electrode. The variable reflectivity unit includes a piezoelectric structure and a layer of liquid reflective material between the first electrode and the piezoelectric structure. A thickness of the layer of the liquid reflective material filled between the piezoelectric structure and the first electrode is changed by deformation of the piezoelectric structure. The light-emitting structure is used to emit light for displaying the image.
