This application provides a display device, a screen raising / lowering method, and peripheral devices. The method includes: in response to a power-on command, entering a broadcast state and sending a first broadcast packet to a peripheral device; scanning for a second broadcast packet sent by the peripheral device, and in response to detecting the second broadcast packet, executing a power-on process; in response to a power-off command, generating a screen raising command and sending the screen raising command to the peripheral device; receiving a third broadcast packet from the peripheral device; and in response to the third broadcast packet, executing a power-off process. The method establishes a wireless communication connection with the peripheral device via broadcast packets. In response to a power-on command, it executes a power-on process upon receiving a notification to lower the screen; in response to a power-off command, it executes a power-off process upon receiving a notification to raise the screen. This avoids the time difference caused by manual power-on / off, thereby solving the problem of screen raising / lowering being out of sync with the power-on / off state when turning on or off a display device such as a laser TV.
