For example, with the display device shown in fig. 8A, the user touches the key 2 for the first time, and the controller controls the display to show the signal source menu, where the display interface of the display can refer to fig. 9A. Wherein the signal source menu 3 may include: live tv controls, HDMI1 controls, HDMI2 controls, AV controls, seek remote control controls 31, and power off controls … …. When the signal source menu is displayed on the display, the controller controls the focus 4 to move one control piece downwards each time the user touches the key 2. Fig. 9B shows the display interface of the display when the focus moves to find the remote control 31.

For another example, with the display device shown in fig. 8B, the user touches the button 25 for the first time, and the controller controls the display to display the signal source menu, where the display interface of the display can refer to fig. 9A. When the display shows the signal source menu, the controller controls the focus 4 to move one control element downward every time the user touches the button 24, or controls the focus 4 to move one control element upward every time the user touches the button 22.

The duration of the first preset time is not limited in this embodiment, and the first preset time may be set according to requirements, for example, in a feasible embodiment, the first preset time may be 5 s.

For example, with the display device shown in fig. 8B, the user touches the key 25 for the first time, and the controller controls the display to display the signal source menu. In an application scene of a display interface of a display, when a user touches a key 24 once, a controller controls a focus 4 to move a control downwards, and when the focus moves the control, the controller starts to count the stay time of the focus on the control; in the application, the stay time of the focus in the live television control, the HDMI1 control, the HDMI2 control and the AV control is less than a first preset time. When the focus moves to the searching remote controller control 31, the controller starts to count the stay time of the focus in the searching remote controller control 31; in the present application, the time that the focus stays in the search for the remote control 31 is longer than the first preset time, and the controller generates a start instruction.

In a possible embodiment the validation operation may be: and when the focus moves to the position for searching the remote controller control, responding to the touch of the user on the confirmation control, and generating a control instruction by the controller.

For example, with the display device shown in fig. 8B, the user touches the key 25 for the first time, and the controller controls the display to display the signal source menu. When the signal source menu is displayed on the display, the controller controls the focus 4 to move one control down each time the user touches the button 24, and the focus moves one control each time. When the focus moves to find the remote control 31, the user touches the key 25, triggering the controller to generate a start instruction.

For example, in a possible embodiment the second preset time may be 3 min.

To reduce the waiting time of the user, in a feasible embodiment, the setup time of the communication channel may be: when the display device is started, the controller actively establishes a communication channel. Under normal conditions, the communication channel is always in a connected state. In some application scenarios, the communication path may be in a chopped state due to network, signal strength, and other factors.

In some feasible embodiments, in order to shorten the time taken by the user to search for the remote controller, the controller may determine whether the communication path between the controller and the remote controller is in a connected state every preset time interval, and if the communication path between the controller and the remote controller is in a chopped state, the controller actively establishes the communication channel again to ensure that the communication path is in a connected state when the user needs to search for the remote controller.
