Display apparatus and control method

The embodiment of the invention belongs to the technical field of display, and provides a display device and a control method, the display device comprises a display and a processor connected with the display, and the processor is configured to: determine an LED area corresponding to a target display area in response to an instruction of performing naked eye three-dimensional display in the target display area of the display; and increasing the current of an LED contained in the LED area and reducing the deflection degree of liquid crystal molecules of an adjacent display area of the target display area so as to adjust the brightness of pictures corresponding to the target display area and the adjacent display area. The brightness of the naked-eye three-dimensional display area and the brightness of the naked-eye two-dimensional display area can be kept consistent, namely, the brightness of the whole display picture is kept consistent, so that the picture quality performance of the display equipment can be im
