Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
The embodiment of the disclosure provides a method for controlling screen turning-off of a display screen of a terminal device. Fig. 1 is a flowchart illustrating a method for controlling turning off a display screen of a terminal device according to an exemplary embodiment, where as shown in fig. 1, the method for controlling turning off the display screen of the terminal device is used in the terminal device, and includes the following steps:
in step S11, obtaining a remaining duration of screen-off of the display screen of the terminal device;
in step S12, if the obtained remaining duration of screen blanking is less than the preset value, identifying the content of the current interface of the display screen of the terminal device;
in step S13, when the characteristic value of the content of the text on the current interface of the display screen of the terminal device is greater than the preset threshold, the screen-on duration of the terminal device is extended according to the preset rule.
In the method for controlling the screen turning-off of the display screen of the terminal equipment, the screen turning-off residual time of the display screen of the terminal equipment is obtained in order to conveniently control the screen turning-off of the display screen of the terminal equipment, if the screen turning-off residual time is smaller than a preset value, the content of the current interface of the display screen of the terminal equipment is identified, and if the characteristic value of the content of the text content of the current interface is larger than a preset threshold value, the screen turning-on time of the terminal equipment is prolonged according to a preset rule.
The remaining duration of the off-screen of the display screen of the terminal device may be obtained in any manner. For example, in order to save the power consumption of the screen, the terminal device automatically turns off the screen and enters a screen locking state when the system has a default time and the terminal device does not perform any operation. A timer may be set within the terminal device to time the system default duration. And if the timer counts down, the remaining duration of the timer is the screen-off remaining duration of the terminal equipment. If the timer is positive, the difference value obtained by subtracting the positive timing time length of the timer from the default time length of the system is the screen-off remaining time length of the display screen of the terminal equipment.
The preset value can be determined according to needs, for example, if the system default time of the screen-off of the display screen of the terminal device is 2 minutes, the preset value can be set to 30 seconds. And when the acquired remaining screen-off duration is less than the preset value, delaying screen-off in order to determine whether to prolong the screen-on duration, and identifying the content of the current interface of the display screen of the terminal equipment. And if the characteristic value of the content of the text on the current interface of the display screen of the terminal equipment is greater than the preset threshold value, prolonging the screen-on duration of the display screen of the terminal equipment and delaying screen-off.
When the screen-on duration of the display screen of the terminal equipment needs to be prolonged, the screen-on duration can be automatically prolonged, and a user can be prompted whether the screen-on duration is prolonged or not.
The terminal device may be, for example, a mobile phone, a PAD, a notebook, or a computer.
The condition that the content of the text on the current interface of the display screen of the terminal device is greater than the preset threshold value may include:
the word number of the text content of the current interface of the display screen of the terminal equipment is greater than a first preset threshold value; or
The ratio of the area occupied by the text content of the current interface of the display screen of the terminal equipment to the area of the display screen of the terminal equipment is larger than a first preset threshold value.
When the content of the current interface of the display screen of the terminal device is recognized to include the text content, the word number of the recognized text content can be counted, and if the word number is larger than a first preset threshold value, the screen-on duration of the display screen of the terminal device can be prolonged according to a preset rule. For example, if the first preset threshold is 500 words, the word number of the word content of the current interface on the display screen of the terminal device is 600 words, and the 600 words are greater than 500 words, the screen-on duration of the display screen of the terminal device may be extended according to the preset rule.
The first preset threshold may be set in consideration of the average human reading speed and the system default time length for turning off the display screen of the terminal device, for example, if the average human reading speed is 500 words/minute, the system default time length is 1 minute. The number of words that can be read in 1 minute is 500 words. If the text content of the current interface of the display screen of the terminal device exceeds 500 characters, reading or browsing cannot be completed within the default time length of the system, so that the 500 characters can be used as a first preset threshold value, and when the text content exceeds the first preset threshold value, the screen-on time length of the display screen of the terminal device needs to be prolonged. The first preset threshold may be set according to other manners as needed, and the setting manner of the first preset threshold is only described as an example.
When it is recognized that the content of the current interface of the display screen of the terminal device includes the text content, it may be determined whether a ratio of an area occupied by the text content of the current interface of the display screen of the terminal device to an area of the display screen of the terminal device is greater than a second preset threshold. If the current time is greater than the preset time, the screen-on duration of the display screen of the terminal equipment can be prolonged according to preset rules. The method for determining the ratio of the area occupied by the text content of the current interface of the display screen of the terminal device to the area of the display screen of the terminal device may be any method, for example, the number of words of the text content of the current interface of the display screen of the terminal device may be counted first, the area occupied by each word is determined, and then the area occupied by all the text contents is calculated. And comparing the areas of all the text contents with the area of the current interface of the display screen of the terminal equipment to obtain the ratio of the area occupied by the text contents of the current interface of the display screen of the terminal equipment to the area of the display screen of the terminal equipment. The second preset threshold may be set as desired, for example 50%. Namely, when the ratio of the area occupied by the text content of the current interface of the display screen of the terminal device to the area of the display screen of the terminal device is greater than 50%, the screen-on duration of the display screen of the terminal device can be prolonged according to the preset rule.
According to the method for controlling the screen-off of the display screen of the terminal equipment, when the representation value of the content of the text on the current interface of the display screen of the terminal equipment is larger than the preset threshold value, the screen-on duration of the terminal equipment is prolonged according to the preset rule, so that the screen-off duration of the terminal equipment can be adjusted according to needs in a specific scene, and the flexibility of the control of the screen-off duration is improved.
The present disclosure provides a method for controlling screen-off of a display screen of a terminal device, as shown in fig. 2, fig. 2 shows a flowchart of a method for prolonging a screen-on duration of the terminal device according to a preset rule in step S13 in fig. 1:
in step S131, determining a reading duration of a text on a current interface of a display screen of the terminal device;
in step S132, if the reading duration is longer than the system default duration for turning off the display screen of the terminal device, determining an extended duration of the screen-on duration of the display screen of the terminal device according to the reading duration and the system default duration;
in step S133, the screen-on duration of the display screen of the terminal device is extended according to the determined extended duration.
In the method for controlling the screen-off of the display screen of the terminal device, provided by the disclosure, in order to determine the extended duration for extending the screen-on duration of the display screen of the terminal device, the reading duration of the text on the current interface of the display screen of the terminal device can be determined, and if the reading duration of the text on the current interface of the display screen of the terminal device is greater than the system default duration for the screen-off of the display screen of the terminal device, the extended duration for the screen-on duration of the display screen of the terminal device is determined according to the determined reading duration and the system default duration.
After the reading duration of the text content of the current interface of the display screen of the terminal device is determined, the extended duration of the screen-on duration of the display screen of the terminal device can be obtained according to the system default duration of the screen-off of the display screen of the terminal device. For example, a duration obtained by subtracting a system default duration of turning off the display screen of the terminal device from a reading duration of the text content of the current interface of the display screen of the terminal device may be used as an extension duration of the screen-on duration of the display screen of the terminal device. The reading time of the text content on the current interface of the display screen of the terminal device is subtracted by the system default time of the screen off of the display screen of the terminal device, and the preset time is added to be used as the extension time of the screen on time of the display screen of the terminal device, so that the text content on the current interface of the display screen of the terminal device can be fully browsed.
The present disclosure provides a method for controlling turning off a display screen of a terminal device, as shown in fig. 3, fig. 3 shows a flowchart of a method for determining a reading duration of a text on a current interface in step S131 in fig. 2:
in step S1311, a reading duration of the text content on the current interface is determined according to the word count and the preset reading speed of the text content on the current interface of the display screen of the terminal device.
According to the control method for turning off the display screen of the terminal equipment, the reading time of the text content of the current interface can be determined according to the word number and the preset reading speed of the text content of the current interface of the display screen of the terminal equipment. The preset reading speed may be any set reading speed, and may be, for example, an average human reading speed. After the character content of the current interface of the display screen of the terminal equipment is identified, the word number of the character content is obtained, and then the reading time length of the character content of the current interface of the display screen of the terminal equipment can be determined according to the preset reading speed.
The present disclosure provides a method for controlling screen turning-off of a display screen of a terminal device, as shown in fig. 4, fig. 4 is a flowchart illustrating a method for identifying content of a current interface of the display screen of the terminal device in step S12 in fig. 1:
in step S121, when the current interface of the display screen of the terminal device is in the picture format, identifying text content in the picture;
when the current interface of the display screen of the terminal equipment is a static interface in a non-picture format, analyzing the current interface to obtain the text content, or capturing the current interface to identify the text content in the captured picture.
In the screen-off control method for the display screen of the terminal equipment, when the current interface of the display screen of the terminal equipment is in a picture format, the text content in the picture can be directly identified. When the current interface of the display screen of the terminal device is a static interface other than a picture, for example, a current interface webpage of the display screen of the terminal device or a wechat public number character, the text content of the current interface can be directly identified, or the current interface is captured to form a picture, and then picture character identification is performed. The tool for picture character recognition may use any recognition tool existing, for example, ocr (optical character recognition) picture recognition tool.
When the current interface has both text content and pictures, the text content part can be directly identified, then the picture part is identified by using a picture identification tool, and then the identification results of the text content part and the picture part are added to form a complete identification result.
The embodiment of the disclosure provides a method for controlling screen turning-off of a display screen of a terminal device. Fig. 5 is a flowchart illustrating a method for extending the screen-on duration of the terminal device according to the preset rule in step S13 in fig. 1:
in step S134, invoking a floating window to display a prompt message, where the prompt message includes whether to prolong a screen-on duration of a display screen of the terminal device;
in step S135, the screen-on duration of the display screen of the terminal device is extended according to the selection of the prompt message by the user of the terminal device.
In the method for controlling the screen-off of the display screen of the terminal device, when the representation value of the content of the text on the current interface of the display screen of the terminal device is greater than the preset threshold value, the floating window can be called to display the prompt information to prompt a user whether to prolong the screen-on duration of the display screen of the terminal device. And determining whether the screen-on duration of the display screen of the terminal equipment is prolonged or not according to the selection of the user of the terminal equipment on the prompt message. The prompt message may only prompt the user of the terminal device whether to extend, if the user of the terminal device selects extension, for example, there is a yes or no option in the floating window, and if the user of the terminal device selects yes, the screen-on duration of the display screen of the terminal device is extended according to the default extended duration of the system. The method and the device can also give the extension time when prompting whether the user of the terminal equipment extends the screen-on time of the display screen of the terminal equipment or not so as to enable the user of the terminal equipment to know the extension time. The user of the terminal equipment can select the extension time length while prompting whether the user of the terminal equipment extends the screen-on time length of the display screen of the terminal equipment, so that the user of the terminal equipment can flexibly select the required extension time length. Or within a given time length, when the user of the terminal equipment does not select the prompt message displayed in the floating window, the default permission extension is carried out, and the default extension time length of the system is extended.
The embodiment of the disclosure provides a method for controlling screen turning-off of a display screen of a terminal device. Fig. 6 is a flowchart illustrating a control method for turning off a display screen of a terminal device according to an exemplary embodiment:
in step S14, acquiring a duration for identifying the content of the current interface of the display screen of the terminal device;
in step S15, if the duration of the content of the current interface of the display screen of the terminal device is longer than the remaining duration of the screen-off state, when the screen-off time of the terminal device is reached, the screen-on state of the display screen of the terminal device is maintained.
In the method for controlling the screen-off of the display screen of the terminal device, a certain time is needed for identifying the content of the current interface of the display screen of the terminal device, the duration for identifying the content of the current interface of the display screen of the terminal device can be compared with the acquired remaining duration for screen-off, and if the duration is longer than the remaining duration for screen-off. The screen locking method is used for indicating that the time for turning off the screen and entering the screen locking state is up to the time when the content of the current interface of the display screen of the terminal equipment is not identified. Therefore, if the display screen of the terminal equipment is directly turned off according to the system default time length of the display screen of the terminal equipment and enters a screen locking state, the purpose required by the method provided by the disclosure cannot be achieved, namely, the screen lightening time length is prolonged when the screen lightening time length needs to be prolonged. Therefore, in the method for controlling the screen-off of the display screen of the terminal device provided by the disclosure, the duration for identifying the content of the current interface of the display screen of the terminal device is compared with the acquired remaining duration for screen-off, and if the duration is longer than the remaining duration for screen-off, the screen is not turned off even when the screen-off time of the terminal device is up, but the screen-on state of the display screen of the terminal device is maintained.
The duration of identifying the content of the current interface of the display screen of the terminal device may be set as desired, for example, to 30 seconds. And an identification estimation value can be given according to the characteristics of the content of the current interface of the display screen of the terminal equipment. For example, if the current interface of the display screen of the terminal device is a picture, the average recognition time of the picture of the current interface size may be used as the recognition prediction value.
