This application provides a display device and a standby method, as well as a far-field voice control method. When the display device is switched from a power-on state to a standby state, the main chip is powered off while the voice chip remains powered on. The voice chip performs a first wake-up task, that is, it recognizes a wake-up command sent by the user and, in response to the recognized wake-up command, instructs the main chip to power on and start. This ensures far-field voice control functionality in standby mode and avoids power consumption by the main chip. Furthermore, when the display device is woken from standby mode by a user's wake-up command, the main chip further executes a voice service to identify the type of voice command and, based on the type of voice command, accurately controls whether the display needs to be turned on, so that the display is only turned on when needed, thereby precisely controlling power consumption after standby mode is activated.
