Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
As shown in fig. 1, a flowchart of embodiment 1 of a method for displaying a display method provided by the present application is applied to an electronic device, and the method includes the following steps:
step S101: when the display condition is met, obtaining first information from first firmware;
the first firmware is used for inputting original image information of a system layer of the electronic equipment into a display unit of the electronic equipment.
The display condition is a condition for triggering display of first information on the display unit, and the first information is at least information stored in the first firmware.
The first information is information with a higher security level, or information that cannot be displayed on the display unit under the current normal condition.
Specifically, when the display condition is satisfied, the first information is obtained from the first firmware.
The first firmware can input original image information of a system layer of the electronic equipment into a display unit of the electronic equipment, and the first information is not directly acquired in the system layer and is acquired in a non-system layer based on the first firmware.
In specific implementation, the first firmware is provided with a storage area for storing the first information, so that the first information is distinguished from information of a system layer, and the first information is directly acquired from a non-system layer.
Specifically, the display condition may be various, and three cases are listed as follows:
firstly, request information used for displaying the first information is detected, and the display condition is determined to be met based on the condition that verification information obtained by the request information meets the condition; or the like, or, alternatively,
secondly, detecting that the electronic equipment receives the first information of the first application, and determining that the display condition is met; or the like, or, alternatively,
thirdly, detecting that the electronic equipment receives the first information of the first application and the first information is updated to the first firmware, and determining that the display condition is met.
As a specific example, as the first case, a user requests to display information with a higher security requirement, such as an account and a password, where the first information is the account and the password, and the account and the password are pre-stored in a preset storage area of a first firmware, when the user requests the first information, the electronic device acquires corresponding verification information after detecting the request information, and based on that the verification information meets a condition, if the account and the password are matched, the verification further determines that the display condition is met, and the account and the password can be displayed.
As a specific example, as in the second case, when it is detected that the electronic device receives a first message of a first application, and it is determined that a condition is satisfied, where a priority level of the first application is lower than a priority level to which display content in a current display unit belongs, the first information may be stored in first firmware, so as to obtain the first information from the first firmware, and display the first message of the first application in combination with original image information of the current display content. Or, the specific message of the specific application is important for the user, the specific message of the application is written into the preset storage area of the first firmware as the first message in advance, when other applications are run, particularly when the priority of the other applications is higher than that of the specific application, when the electronic equipment receives the first information of the first application, the electronic equipment judges that the display condition is met, and displays the specific message.
As a specific example, as described in the third case, it is detected that the electronic device receives a first message of the first application, the reception of the first message is used for updating the first firmware, it is determined that the display condition is satisfied, and the first message is displayed to update the first firmware.
Step S102: processing the first information and the original image information to obtain image information to be displayed;
and processing the first information and the original image information to obtain image information to be displayed, wherein the image information to be displayed comprises the first information and the original image information.
In a specific implementation, this step may be performed by the display unit.
The first information may be stored in the first firmware in various forms such as images, characters, tables, etc., and when it is required to be displayed, the first information may be converted into an image form to be combined with the original image information, or may be directly combined with the original image information.
In a specific implementation, the first information includes non-shared information pre-installed in the first firmware and/or an application message from the first application.
The non-shared information is information with high security requirements, such as privacy information, account number and password.
The first application may be an application in the electronic device that is running in the background.
In a specific implementation, the first information may include a plurality of pieces of non-shared information and/or a plurality of application messages of a certain application and/or application messages of a plurality of applications.
The step S102 may specifically adopt the following specific implementation procedures:
splicing, superposing, compatibilizing or embedding the unshared information and the original image information to obtain an image to be displayed for the display unit; or the like, or, alternatively,
splicing, superposing, compatibilizing or embedding the application message and the original image information to obtain an image to be displayed for displaying on the display unit; or the like, or, alternatively,
processing the non-shared information and the attribute information of the application message into third information based on the non-shared information and the attribute information of the application message; splicing, superposing, compatibilizing or embedding the third information and the original image information to obtain an image to be displayed for displaying on the display unit;
in this processing method, the pieces of information included in the first information are combined, and for example, based on the non-shared information and the attribute information of the application message, the non-shared information and the application message are processed into third information, and the third information may be an image.
The attribute information represents various attributes of the non-shared information and the application message, such as whether the information/message appears in a dialog box form or in a reminding information form, and various attributes such as a font and an occupied area are adopted, and specific content of the attribute information is not limited in the application.
And after the third information is obtained, splicing, superposing, compatibilizing or embedding the third information and the original image information to obtain the image to be displayed.
Specifically, when the splicing mode is adopted, the splicing can be carried out in a left-right arrangement mode or an up-down arrangement mode; when a superposition mode is adopted, superposing the image of the third information to the upper layer of the image of the original image information, so that the image of the original image information is partially shielded by the image of the third information; when the compatible mode is adopted, the specific area in the original image information is compatible with the image of the third information, so that the content in the original image information and the content of the third information image are simultaneously displayed in the specific area; when the embedding mode is adopted, the area corresponding to the third information is scratched out from the original image, and the third information is embedded into the area.
The step S102 may also specifically adopt the following specific implementation process:
and according to a preset arrangement mode, splicing, overlapping, conforming or embedding the non-shared information and/or the application message with the original image information respectively to place the non-shared information and/or the application message in a first area and a second area of the original image respectively to obtain an image to be displayed for displaying.
In the processing mode, each piece of information contained in the first information is processed with the original image information to obtain the image to be displayed.
Specifically, according to a preset arrangement mode, selecting areas corresponding to the non-shared information and the application message in the original image, for example, displaying the non-shared information in a first area, displaying the application message in a second area, then sequentially placing the non-shared information in the first area of the original image, and placing the application message in the second area of the original image.
Specifically, the processing manner includes splicing, superimposing, conforming, or embedding, and the process refers to a process of processing the third information and the original image information, which is not described herein again.
In the following embodiments, detailed descriptions will be given for the drawings and the information of the image to be displayed, and detailed descriptions will not be given in this embodiment.
As a specific example, when the first information only includes non-shared information, the non-shared information and the original image information are subjected to stitching, superimposing, conforming, or embedding processing to obtain an image to be displayed for displaying on the display unit.
The processing mode includes splicing, superimposing, conforming, or embedding, and the process refers to a process of processing the third information and the original image information, which is not described herein again.
As a specific example, when the first information only includes the application message, the application message and the original image information are spliced, superimposed, compatible, or embedded to obtain the image to be displayed for displaying on the display unit.
The processing mode includes splicing, superimposing, conforming, or embedding, and the process refers to a process of processing the third information and the original image information, which is not described herein again.
Step S103: and displaying the image information to be displayed on a display unit.
Specifically, the image information to be displayed is output to a display unit to be displayed in the display unit.
As shown in fig. 2, the information change diagram in this embodiment includes a display unit 201, a first firmware 202, and a processor 203, where the first firmware receives original image information transmitted by the processor, processes first information acquired from a preset storage area of the first firmware and the original image information to obtain image information to be displayed, and sends the image information to the display unit, so that the display unit displays an image corresponding to the first information and the original image information. The processor belongs to a System layer (OS), provides original image information, and the first firmware belongs to a hardware layer, and acquires first information stored in the hardware layer from the hardware layer, and sends the first information and the original image information to the display unit, so that the display unit processes the first information and the original image information to obtain image information to be displayed.
It should be noted that, in the prior art, the screen capture captures the information output by the processor from the system layer to obtain the content displayed on the screen, but in this embodiment, the first information is stored in the first firmware, and the first information is directly output to the display unit after being combined with the original image information, instead of being output to the display unit through the processor, so that the first information is prevented from being captured when the information is captured from the system layer.
In summary, the present embodiment provides a display method, including: acquiring first information from first firmware when a display condition is met, wherein the first firmware is used for inputting original image information of a system layer of the electronic equipment into a display unit of the electronic equipment; processing the first information and the original image information to obtain image information to be displayed; displaying the image information to be displayed on the display unit; the display condition is a condition for triggering display of first information on the display unit, and the first information is at least information stored in the first firmware. In the scheme, the first firmware is provided with a special storage area for storing the first information, and the storage area is isolated from a system of the electronic equipment, so that the information in the storage area cannot be read by the system of the electronic equipment, and the safety of the first information is ensured. Moreover, when the first information is displayed on the display, the first information is combined with the original image information of the system layer of the electronic equipment, even if the image content displayed on the display is intercepted, the first information cannot be intercepted and obtained through the system layer of the electronic equipment, and the safety of the first information is further ensured.
As shown in fig. 3, a flowchart of embodiment 2 of a method for displaying a video is provided, where the method includes the following steps:
step S301: storing the first information to the first firmware through a first driver or a system plug-in if authentication information of a user of the electronic device satisfies a condition;
wherein the verification information includes: authentication information input by a user and/or authentication information automatically obtained by the electronic device.
For example, the verification information input by the user includes biometric information such as fingerprints, faces, irises, and the like, an agreed password, and the like; the automatically obtained verification information includes image information so that recognition is performed based on the image information to obtain a recognition result, and it is determined whether the user is an appointed person or whether the action/posture of the user satisfies the appointed action/posture.
Specifically, the verification information is judged, and when the verification information meets the verification condition, the user is judged to be capable of performing information storage operation on the first firmware.
Specifically, the first information is stored in the first firmware through a first driver or a system plug-in.
Due to the system-level separation of the first firmware and the electronic device, a specific driver or system plug-in is required to store the first information into the first firmware.
For example, the system plug-in employs WMI (Windows Management Instrumentation), which is a core Windows Management technique that users can use to manage the local computer, through which all Windows resources of the local computer are accessed, configured, managed, and monitored.
Specifically, the WMI is a communication form of an upper layer software BIOS (Basic Input Output System), and the WMI is implemented to operate (for example, store or update) the first firmware of the non-System layer based on the uploaded software BIOS.
Step S302: under the condition that the verification information of the user of the electronic equipment meets the condition, updating the obtained second information to the first firmware through a first driver or a system plug-in;
wherein the second information is obtained later than the first information.
In step S302, the electronic device user verifies whether the information satisfies the condition, referring to the explanation in step S301.
In a specific implementation, the step S302 can be implemented by the following steps:
receiving authentication information and an updating request of a user;
establishing a data transmission channel between the first firmware and the first driver or the system plug-in according to the updating request based on the verification of the identity verification information;
acquiring second information from the first driver based on the data transmission channel;
and updating the first firmware according to the second information, wherein the second information can be the same type of information as the first information, such as application messages from the same application or non-shared information, or different types of information as the first information, such as application messages or notification information from different applications.
It should be noted that, in a specific implementation, the step S301 and the step S302 may be sequentially executed in the same application scenario, or may be executed alternatively, and a combination manner of the two is not limited in this application. The first firmware may be updated multiple times in an implementation.
Step S303: when the display condition is met, obtaining first information from first firmware;
step S304: processing the first information and the original image information to obtain image information to be displayed;
step S305: and displaying the image information to be displayed on a display unit.
Steps S303 to 305 are the same as steps S101 to 103 in embodiment 1, and are not described in detail in this embodiment.
In summary, the present embodiment provides a display method, further including: storing the first information to the first firmware through a first driver or a system plug-in if authentication information of a user of the electronic device satisfies a condition; and/or updating the obtained second information to the first firmware through a first driver or a system plug-in when the verification information of the user of the electronic equipment meets the condition, wherein the second information is obtained later than the first information. In this embodiment, when the used verification information satisfies the condition, the first firmware may be stored or updated by the first driver or the system plug-in.
As shown in fig. 4, a flowchart of embodiment 3 of a method for displaying a video is provided, where the method includes the following steps:
step S401: when the display condition is met, obtaining first information from first firmware;
step S401 is the same as step S101 in embodiment 1, and details are not described in this embodiment.
Step S402: obtaining an image frame displayed on the display unit at a first moment or a first moment and adjacent moments thereof at least based on the original image information;
the method comprises the steps that based on original image information acquired from a system layer, an image frame displayed on a display unit at a first moment is acquired, the first moment can be the same as/similar to the original image at the moment of image display, and the adjacent moment is the moment before/after the first moment, wherein the time interval between the adjacent moment and the first moment can be preset, and the adjacent moment can also be the moment before/after the first moment at which an adjacent frame of image is displayed; the first time may also be a current time, and the adjacent time is specifically a time before the first time, or a time when an adjacent frame of image is displayed before the first time.
Specifically, the image frame displayed in the display unit at the first time or the first time and the time adjacent to the first time is acquired based on the original image information.
Specifically, the image frame is acquired from the display unit, and may also be acquired from a system layer.
The obtaining from the system layer includes obtaining from an EC (system controller), a GPU (graphics processing unit), or a CPU (central processing unit).
Step S403: combining the first information with the image frame in a preset mode based on the first information and the display parameters of the image frame to obtain an image to be displayed for displaying on the display unit;
wherein the first time and its neighboring time are related to the display condition.
Wherein the display parameters include: color, size, resolution, and display content, etc.
Specifically, the first information and the image frame are respectively analyzed to obtain display parameters of the first information and the image frame, and the first information and the image frame are combined according to a preset mode to obtain an image to be displayed.
When the splicing mode is adopted, the splicing can be carried out in a left-right arrangement mode or an up-down arrangement mode; when a superposition mode is adopted, superposing the image of the first information on the upper layer of the image frame so that the image of the first information partially shields the image frame; when the compatible mode is adopted, a specific area in the image frame is compatible with the image of the first information, so that the content in the image frame and the content of the image of the first information are displayed simultaneously in the specific area; when the embedding mode is adopted, the area corresponding to the first information is scratched out from the image frame, and the first information is embedded into the area.
As a specific example, the first information is placed on the uppermost layer of the display layer, so that the image of the first information is superimposed with the image frame information, so that the image of the first information covers a partial area of the original image information, and the image information to be displayed is obtained.
For example, in the case of the first embodiment 1, when a user requests display of first information and verification information obtained based on the request information meets the condition, and the time when the request is received is taken as the first time, the first information is combined with the image frame at the first time and the adjacent time in the display unit to obtain an image to be displayed including the image frame and the content of the first information image.
For example, in the second case of embodiment 1, when the electronic device receives a first message of a first application running in the background from the system layer, the time when the first message is received is taken as a first time, the first message is stored in a preset storage area of the first firmware, and after the first message is obtained from the first firmware, the first message is combined with an image frame at the first time and at an adjacent time in the display unit to obtain an image to be displayed including the image frame and the content of the first information image.
For example, when the display condition is the third condition in embodiment 1, when the electronic device receives a first message of a first application running in the background from the system layer, and updates the first information to the first firmware, the time when the first information is updated to the first firmware is taken as the first time, the first information is acquired from the preset storage area of the first firmware, and the first information is combined with the image frame at the first time and the image frames at the adjacent times in the display unit to obtain the image to be displayed including the image frame and the content of the first information image.
As a specific example, the first information is superimposed with the image frame information, so that an image of the first information covers a partial area of the original image information, resulting in image information to be displayed.
Step S404: and displaying the image information to be displayed on a display unit.
Step S404 is the same as step S103 in embodiment 1, and details are not described in this embodiment.
In summary, in the display method provided in this embodiment, the processing the first information and the original image information to obtain image information to be displayed includes: obtaining an image frame displayed on the display unit at a first moment or a first moment and adjacent moments thereof at least based on the original image information; combining the first information with the image frame in a preset mode based on the first information and the display parameters of the image frame to obtain an image to be displayed for displaying on the display unit; wherein the first time and its neighboring time are related to the display condition. In this embodiment, an image to be displayed is obtained based on the combination of the image frame displayed in the display unit and the first information, and the first information is displayed in the display unit.
