A display device control method includes when an operation on an on-screen display (OSD) input device is received, determining whether a signal generated by operating the OSD input device is currently sent to an OSD system or an operating system (OS); and when the signal generated by operating the OSD input device is currently sent to the OS, switching, according to a control signal generated by the OSD input device, the control signal from being sent to the OSD system to being sent to the OS. This application further provides a display device.

A piezoelectric microphone, includes: a wafer substrate including a cavity; a plurality of cantilever beams with a piezoelectric deck structure; a fixed column; a plurality of flexible elastic members; and a connecting section. The plurality of cantilever beams each includes a fixed end and a free end suspended above the cavity. The plurality of cantilever beams is of a structure in which one end is narrow and the other end is wide, and the fixed end is relatively narrow. The fixed column is disposed at the center of the bottom surface of the cavity. The fixed ends of the plurality of cantilever beams are all connected to the top surface of the fixed column. A gap is provided between every two adjacent cantilever beams. The plurality of flexible elastic members is connected to free ends of two adjacent cantilever beams to enable the cantilever beams to vibrate synchronously.
