Background switching method and display device

Abstract

A background switching method and a display device are disclosed. The background switching method is applicable to a display device including a physical switching component, a processor, and a screen. The method includes: generating a switching signal by triggering the physical switching component with an external force; obtaining a user command based on the switching signal by the processor; switching the current extended display identification data of the display device to target extended display identification data by the processor according to the user command; controlling the screen according to the target extended display identification data by the processor, such that the size of the screen's display image is smaller than the size of the screen's display image in full-screen mode, and a background area exists between the display image corresponding to the target extended display identification data and the screen's border; and setting the background area as the designated image by the processor.

Claims

1. A background switching method applicable to a display device including a physical switching element, a processor, and a screen, the method comprising: generating a switching signal by the physical switching element being triggered by an external force; obtaining a user instruction based on the switching signal by the processor; switching a current extended display identification data of the display device to a target extended display identification data by the processor according to the user instruction; controlling the screen according to the target extended display identification data by the processor, such that the size of a display screen of the screen is smaller than the size of the display screen in a full-screen mode, and a background area is formed between the display screen corresponding to the target extended display identification data and the border of the screen; and setting the background area as a designated screen by the processor, wherein obtaining the user instruction based on the switching signal by the processor comprises: controlling the screen to display an identification data selection interface, wherein the identification data selection interface includes multiple options corresponding to multiple candidate extended display identification data; and taking the triggered option as the user instruction.

2. The background switching method as described in claim 1, wherein setting the screen of the background area as the designated screen by the processor includes: receiving a setting instruction corresponding to a target background screen among a plurality of candidate background screens; and setting the target background screen as the designated screen.

3. The background switching method as described in claim 1, wherein the processor is connected to a host, and setting the screen of the background area as the designated screen by the processor includes: receiving a current timestamp from the host; determining a target background screen from a plurality of candidate background screens based on the current timestamp; and using the target background screen as the designated screen.

4. The background switching method as described in claim 1, wherein the processor is connected to a host, and setting the screen of the background area as the designated screen by the processor includes: receiving a pattern file from the host; and using the pattern file as the designated screen.

5. A display device, comprising: a physical switcher for generating a switching signal triggered by an external force; a screen; and a processor connected to the physical switcher and the screen, the processor being configured to: retrieve a user instruction based on the switching signal; switch a current extended display identification data of the display device to a target extended display identification data according to the user instruction; control the screen according to the target extended display identification data such that the size of a display screen on the screen is smaller than the size of the display screen in a full-screen mode, and a background area is formed between the display screen corresponding to the target extended display identification data and the border of the screen; and set the background area as a designated screen, wherein the processor is configured to control the screen to display an identification data selection interface, wherein the identification data selection interface includes multiple options corresponding to multiple candidate extended display identification data; and use the triggered option as the user instruction.

6. The display device as claimed in claim 5, wherein the processor is configured to receive a setting instruction corresponding to a target background image among a plurality of candidate background images; and to use the target background image as the designated image.

7. The display device as claimed in claim 5, wherein the processor is further configured to connect to a host, and the processor is configured to receive a current timestamp from the host; determine a target background image from a plurality of candidate background images based on the current timestamp; and use the target background image as the designated image.

8. The display device as claimed in claim 5, wherein the processor is further configured to connect to a host computer, and the processor is configured to receive a pattern file from the host computer; and to use the pattern file as the designated screen.
