1 is a schematic structural view of a display device according to a first embodiment of the present invention; and FIG. 2 is a flowchart of a screen keep-alive control method according to a second embodiment of the present invention.

The present invention is not limited by the embodiments, and the embodiments of the present invention are not intended to limit the invention to any specific environment, application or special mode as described in the embodiments. Therefore, the description of the embodiments is merely illustrative of the invention and is not intended to limit the invention. In the following embodiments and drawings, elements that are not directly related to the present invention are omitted and are not shown, and the dimensional relationships between the elements in the drawings are merely for ease of understanding and are not intended to limit the actual implementation.

A first embodiment of the present invention is used to describe a display device, and FIG. 1 is a schematic structural view of a display device according to the embodiment. As shown in FIG. 1, the display device 1 includes a processor 11 and a screen 13 electrically connected to the processor 11. The embodiment of the display device 1 may be a cathode ray tube display, a liquid crystal display, or a touch screen such as a display device; and the display device 1 can be connected to a personal computer, a tablet, or a note according to different application scenarios. Hosts in devices such as computers, digital cameras, personal digital assistants (PDAs), and mobile phones interact to display information that each host wants to provide to the user.

The processor 11 is configured to determine the information 20 according to the complexity of the information 20 During a first display period, the screen 13 is used to keep the information 20 for the first display period. Information 20 is visual information, including one or a combination of text information, picture information, and video information. Text information refers to various texts/paragraphs, symbols, numbers, or combinations thereof, and the representation of text information is not limited to a specific language. Picture information refers to various images, scenes, photos, etc., and the representation of picture information is not limited to a specific format. Video information refers to various animations, as well as combinations of continuous images, continuous scenes, or continuous photos, and the representation of movie information is not limited to a specific format.

Further, the complexity of the information 20 is related to the nature of the information 20, and the nature of the information 20 may include, but is not limited to, information size, typesetting, readability, and the like. In general, the greater the amount of information 20, the more messy the layout, or the lower the readability, the longer the user will need to complete the information 20 in full. Conversely, the smaller the information amount of the information 20, the more regular the layout or the higher the readability, the shorter the time required for the user to completely obtain the information 20.

The processor 11 can extract the text information, the picture information and the video information contained in the information 20 by analyzing the content of the information 20. Then, the processor 11 individually determines the time required for the user to read the text information, the picture information, and the video information according to the information amount, the typesetting manner, the readability, and the like of the information 20, thereby estimating the user's complete acquisition. The time required for information 20. For example, assume that the information 20 includes 100 words, 10 pictures, and 2 movies, and the processor 11 determines that the time for each user to read each text, each picture, and each movie is 0.1 seconds, 2 seconds, and 10 seconds, the processor 11 estimates that the time required for the user to completely obtain the information 20 is 50 seconds. For those of ordinary skill in the art, how to analyze the information 20 to extract the text information, the picture information, and the video information contained in the information 20 is a conventional technique, and thus is not described here.

On the other hand, the nature of the application itself will affect the aspect of the information 20, and the different aspects of the information 20 will affect the time required for the user to fully obtain the information 20. Assuming that the information 20 corresponds to a word processing application, such as Microsoft Office, the information 20 can be regarded as the file content executed by the document processing application. Assuming information 20 corresponds to a web browsing application, such as Microsoft Internet Explorer, information 20 can be viewed as web content viewed through the web browsing application. Assuming that the information 20 corresponds to a media playing application, such as Microsoft Media Player, the information 20 can be viewed as the media content played by the media playing application.

Accordingly, the processor 11 can determine the first display period based on the complexity of the information 20 and/or based on the nature of the application, thereby estimating the time required for the user to fully obtain the information 20. In detail, the processor 11 can roughly determine the first display period of the information 20 based on the nature of the application corresponding to the information 20. The processor 11 can also finely estimate the first display period of the decision information 20 according to the complexity of the information 20, wherein the first display period is proportional to the complexity of the information 20. Once the processor 11 determines the first display period of the information 20, the screen 13 can learn the first display period of the information 20 from the processor 11 and display the information 20 during the first display period. In other words, the screen 13 will keep the information 20 in the first display period.

In order to adaptively estimate the time required for the user to obtain the complete information 20, the display device 1 optionally further includes the following operations. In detail, the processor 11 can adaptively adjust the display period of the information 20 so that the display period of the screen 13 keep-alive information 20 can be closer to the time required for the user to obtain the complete information 20.

Further speaking, the first display of the live information 20 on the screen 13 During the period, if a display interruption event occurs, it indicates that the user may have completely obtained the information 20 before the expiration of the first display period. At this time, the processor 11 sets the first display period of the shortened information 20 to a second display period, and the screen 13 displays the information 20 by replacing the first display period with the second display period. In other words, the screen 13 is adapted to use the keep-alive information 20 during the second display period. The display interruption event includes various operations for causing the screen 13 to stop displaying the information 20, such as but not limited to: the user manually presses a power key to turn off the screen 13; and the user puts down the electronic product including the display device 1 and the like. .

For example, if the first display period of the information 20 is 50 seconds, and the user manually presses the power button to turn off the screen 13 10 seconds before the expiration of the first display period, the processor 11 determines the second display period. It is 40 seconds. Thus, when the display device 1 displays the same information 20 again, the screen 13 changes to the keep-alive information 20 within 40 seconds.

In addition, after the first display period of the screen 13 keep-alive information 20, if a display continuation event occurs, it indicates that the user may not completely obtain the information 20 before the expiration of the first display period. At this time, the processor 11 sets the first display period of the extended information 20 to a third display period, and the screen 13 displays the information 20 by replacing the first display period with the third display period. In other words, when the information 20 is displayed next time, the screen 13 is used for the keep-alive information 20 during the third display period. The display continuation event includes various operations for causing the screen 13 to continue displaying the information 20, such as, but not limited to, when the electronic product including the display device 1 is in a position that can be read by the user, the user manually presses the power button to turn on the screen 13; And the user shakes the electronic product including the display device 1 to turn on the screen 13 and the like.

For example, assume that the first display period of the information 20 is 50 seconds. After the first display period expires and the screen 13 is turned off, the user manually presses the power button to turn on the screen 13, and after 10 seconds, manually presses the power button to turn off the screen 13, the processor 11 determines the third display. The period is 60 seconds. Thus, when the display device 1 displays the same information 20 again, the screen 13 is changed to the keep-alive information 20 within 60 seconds.

The second embodiment of the present invention is for explaining a screen keep-alive control method for a display device, and FIG. 2 is a flow chart of the screen keep-alive control method according to the embodiment. The display device of the embodiment is substantially the same as the display device 1 of the first embodiment. Therefore, the display device of the embodiment includes a processor and a screen electrically connected to the processor.

As shown in FIG. 2, in step S201, the processor determines a first display period of the information according to the complexity of the information. In other embodiments of the present invention, step S201 may be the step of causing the processor to determine the first display period according to the complexity of the information and the nature of the application corresponding to the information. In step S203, the screen is kept in the first display period.

In principle, the screen keep-alive control method described in this embodiment may only include the step S201 and the step S203. However, in order to enable the display device to adaptively estimate the time required for the user to obtain the complete information, the screen keep-alive control method described in this embodiment may further include the following steps. In detail, in step S205, the first display period in which the processor shortens the information is a second display period in response to a display interruption event occurring during the first display period; and then in step S207, The screen changes to keep the information in the second display period. In addition, in step S209, the first display period in which the processor extends the information is a third display period according to a display continuation event that occurs after the first display period; and then in step S211, the screen is changed. The information is kept live during the third display period.

In addition to the above steps, the second embodiment of the present invention can also perform the steps corresponding to all operations of the display device 1 described in the above first embodiment. A person having ordinary knowledge in the technical field of the present invention can directly understand how the screen keep-alive control method described in this embodiment performs the corresponding steps according to the disclosure of the first embodiment, and details are not described herein.

The above embodiments are only intended to illustrate the embodiments of the present invention, and to explain the technical features of the present invention, but are not intended to limit the scope of protection of the present invention. Any change or equivalent arrangement that can be easily accomplished by those skilled in the art is within the scope of the invention, and the scope of the invention is subject to the scope of the patent application.
