Detailed Description
The following detailed description of embodiments of the present application will be made with reference to the accompanying drawings and examples. The following examples are intended to illustrate the present application but are not intended to limit the scope of the present application.
Those skilled in the art will understand that, in the embodiments of the present application, the size of the serial number of each step described below does not mean the execution sequence, and the execution sequence of each step should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
Fig. 1 is a flowchart of a display area dividing method according to an embodiment of the present application, which may be implemented on a display area dividing device, for example. As shown in fig. 1, the method includes:
s120: determining a deformation parameter of a unit area in a display area of a display device;
s140: determining safety parameters of the unit area at least according to the deformation parameters;
s160: and determining a sub-area to which the unit area belongs and the safety level of the sub-area at least according to the safety parameters, wherein the display area comprises the sub-area.
According to the method, the display area is divided into the sub-areas with different safety levels according to the deformation condition of the display area, and the display content with the corresponding safety levels can be displayed in the corresponding sub-areas based on the sub-areas, so that the display content can be conveniently and safely output.
The functions of steps S120, S140 and S160 will be described in detail below with reference to specific embodiments.
S120: a deformation parameter of a unit area in a display area of a display device is determined.
The display device refers to a display device, such as a flexible display device, of which the display area can change shape. The unit area may be, for example, one display pixel, or may be a plurality of display pixels divided in advance.
The deformation parameters are parameters reflecting the deformation condition of the unit area, and at least include deformation direction and deformation angle. In one embodiment, the deformation parameter may be determined according to sensing data output by a sensor built in the display device. The sensor may output different voltage values or resistance values according to the deformation parameters, for example.
The deformation direction refers to a direction in which the unit region is bent, and the deformation direction may be upward or downward. Assuming that the user is always in the viewing position, i.e. on the display side of the display area, the upward, i.e. towards the user, bending downward, i.e. away from the user. Taking fig. 2 as an example, assuming that the bending portion 210 of the display area 200, i.e. the upper right corner portion in fig. 2, corresponds to a unit area, it can be seen that the deformation direction of the unit area is upward at this time.
The deformation angle refers to a degree to which the unit region is bent. Generally the bending includes two cases. One case is shown in fig. 2, in which the upwardly bent portion 210 of the unit area is a plane and the plane directly forms an angle with the main plane of the display area. This is a simple case, and the angle is the deformation angle. Alternatively, as shown in fig. 3, the curved portion of the unit area is smoothly transited, and the side view thereof is curved as shown in fig. 3, so that the deformation angle in this case is the maximum angle that the unit area is rotated. As shown in fig. 3, the deformation angle may obtain a curve as shown in the figure according to the curved surface corresponding to the unit area, then tangent lines are made at different positions of the curve, and finally a group of two tangent lines with the largest included angle is obtained, and then the included angle determined by the two tangent lines is used as the deformation angle.
In addition, it is understood by those skilled in the art that the position information of the unit area on the display area is predetermined. For convenience, the position information may be stored in correspondence with the deformation parameter. The unit area may be any unit area in the display area, and thus, the deformation parameters of all the unit areas in the display area may be obtained.
S140: and determining the safety parameters of the unit area at least according to the deformation parameters.
Referring to fig. 3, it is assumed that the point a corresponds to the first unit area and the point B corresponds to the second unit area, and the point a is shielded by the curved portion because the point a is closer to the curved portion of the display area, so that the first unit area is safer than the second unit area and can be used for displaying some more private information.
The security parameter is a parameter for reflecting the security degree of the unit area. For example, the security parameter may be defined as a number from 1 to 100, and the larger the number, the higher the security degree of the corresponding unit area.
In one embodiment, the step S140 may include:
s141: determining a vertical line corresponding to the unit area according to the deformation parameter, wherein the vertical line passes through a reference point of the unit area and is perpendicular to a tangent plane passing through the reference point;
s142: determining at least one intersection point of at least one plane drawn from the perpendicular line in at least one direction and the display area respectively according to the deformation parameters of other unit areas in the display area, wherein each direction corresponds to at least one intersection point;
s143: and determining the safety parameters of the unit area according to at least one intersection point corresponding to each direction and the reference point.
In step S141, the reference point is a point representing the single-curved region, and may be any point on the unit region, such as a center point of the unit region. Those skilled in the art understand that, in order to determine the security parameter of each unit region more accurately, the area of the unit region should be as small as possible, i.e. the display region is divided into as many unit regions as possible, which also results in a large amount of computation. Of course, those skilled in the art understand that the method may also determine a plurality of reference points on the unit area, and perform the above steps corresponding to each reference point, and the principle is consistent with further dividing the unit area into a plurality of smaller unit areas, and then determining a reference point on each smaller unit area, which is not described again.
In this step, the current shape of the unit area may be obtained according to the deformation parameter, and then a tangent plane passing through the reference point may be determined, and then the perpendicular line may be determined. The current shape of the unit area obtained according to the deformation parameter may be obtained by using the prior art, for example, the following research results may be referred to: rendl, Christian, DavidKim, Sean Fanello, Patrick Parzer, Christoph Rhemann, Jonathan Taylor, MartinZirkl "FlexSense a transparent self-sensing deformable surface," In proceedings of the 27th annual ACM symposium on User interface software and technology, pp.129-138.ACM,2014.
And if the unit area is in a plane shape, namely a non-curved surface, the tangent plane is the plane where the unit area is located.
In the step S142, the current shape of the other unit areas in the display area may be obtained according to the deformation parameters of the other unit areas in the display area. The at least one plane drawn from the perpendicular in at least one direction may be referred to fig. 4, where a first plane 410 represents the tangent plane, point O represents the reference point, and line L represents the perpendicular, and then a second plane 420 represents the plane drawn from the perpendicular. Assuming that the direction indicated by the straight arrow in fig. 4 is the initial direction, the second plane 420 can rotate around the vertical line along the curved arrow in the figure, and can rotate up to 360 degrees. Therefore, in this step, the at least one direction may be represented by an included angle between the at least one plane and an initial direction, and the included angle is between 0 and 360 degrees. That is to say, each direction corresponds to a plane drawn from the perpendicular, and the number of the planes may be set according to the required precision, for example, one plane may be drawn at intervals of 1 degree, so that 360 planes are drawn in total.
It is understood by those skilled in the art that each of the planes has an infinite number of intersections with the display area, and for simplicity, the intersection of the plane with each unit area within the display area can be reduced to a reference point for that unit area. That is, if the plane intersects with one unit area, the reference point of the unit area is taken as the intersection of the plane and the unit area. As shown in fig. 5, the plane to be bent represents the display area 510, each cell on the plane represents a unit area, the straight line L represents a perpendicular line passing through the reference point O of the first unit area 511, and the plane to the right of the perpendicular line represents a plane 520 drawn from the perpendicular line, assuming that the current corresponding direction of the plane 520 is the initial direction. The plane 520 intersects the display area 510 to form an intersection line indicated by a black and thick line in fig. 5. The intersection line includes P, Q, R, S, T, U, V, W a series of intersections, which are reference points of the second unit area 512, the third unit area 513, the fourth unit area 514, the fifth unit area 515, the sixth unit area 516, the seventh unit area 517, the eighth unit area 518, and the ninth unit area 519, respectively. That is, the series of intersection points P, Q, R, S, T, U, V, W are the intersection points corresponding to the initial direction. Similarly, the intersection points corresponding to other directions can be obtained by rotating the plane 520 around the vertical line.
In one embodiment, the step S143 may further include:
s1431: determining a minimum one of at least one included angle as a target included angle corresponding to a first direction, wherein the at least one included angle is an included angle between at least one connection line and the vertical line respectively, the at least one connection line is a connection line between at least one intersection point corresponding to the first direction and the reference point respectively, and the first direction is any one direction of the at least one direction;
s1432: and determining the safety parameters of the unit area according to at least one target included angle corresponding to the at least one direction respectively.
For clarity, the intersection points on the perpendicular lines, the intersecting lines and the intersecting lines in fig. 5 are extracted to obtain a simplified diagram as shown in fig. 6. It can be seen that the intersection points P, Q, R, S, T, U, V, W are sequentially connected to the reference point O to obtain a connection line between at least one intersection point corresponding to the initial direction and the reference point O, and these connection lines form a series of included angles with the straight line L, and as can be seen from fig. 5, the angle β is the smallest included angle in the series of included angles, that is, the target included angle corresponding to the initial direction. The first direction is any one of the at least one direction, and therefore, the angle β can be considered as a target included angle corresponding to the first direction.
Similarly, the target included angles corresponding to other directions can be obtained. Assuming that the unit area is not located at the edge of the display area, a number of target angles equal to the number of the at least one direction is finally obtained, and assuming that a total of 360 directions, 360 corresponding target angles are obtained. If the unit area is at the edge of the display area, there will be no corresponding target angle in some directions.
In one embodiment, in step S1432, the safety parameter of the unit area may be determined according to an average value of at least one target included angle respectively corresponding to the at least one direction. For example, 360 target included angles are summed and averaged, and the safety parameter of the unit area is determined according to the average value. Those skilled in the art will appreciate that the smaller the average value, the more the unit area is occluded, and the higher the security level, and accordingly, the higher the value of the security parameter may be.
In addition, if the number of the at least one direction is fixed, the safety parameter of the unit area can also be directly determined according to the angle sum of the at least one target included angle respectively corresponding to the at least one direction.
It will be appreciated by those skilled in the art that the security parameters for all unit areas within the display area can be derived in accordance with the principles described above.
S160: and determining a sub-area to which the unit area belongs and the safety level of the sub-area at least according to the safety parameters, wherein the display area comprises the sub-area.
In one embodiment, the step S160 may include:
s161: according to the safety parameters and the safety parameters of other unit areas in the display area, clustering the unit areas and other unit areas in the display area;
s162: and determining the sub-area to which the unit area belongs and the safety level of the sub-area according to the processing result.
And performing clustering processing on the unit area and other unit areas in the display area, namely performing clustering processing on all the unit areas in the display area. The result of the clustering process is to divide the unit areas with the same or close safety parameters into one sub-area. In practical applications, the number of the sub-regions into which the display region is divided may be set according to requirements. For example, assuming that it is required to divide the display area into 4 sub-areas, the result of the clustering process is to divide all the unit areas into 4 classes, and the unit areas in each class are continuous.
The safety level is used to reflect the safety degree of the sub-region, and generally, the higher the value of the safety parameter of a unit region in the sub-region is, the higher the safety level of the sub-region is.
In one embodiment, the method may further comprise:
s170: and displaying corresponding display content corresponding to the safety level of the sub-area.
In practical applications, the content to be displayed may be marked with a security level, and then the displayed content with the same security level as that of the sub-area may be displayed in the sub-area. For example, assume that the display area includes three sub-areas: the safety levels of the first sub-area, the second sub-area and the third sub-area are 1, 2 and 3 in sequence; if the corresponding display content comprises personal financial information, chat content and news content, the security level of the personal financial information can be marked as 3, the security level of the chat content is 2, and the security level of the news content is 1; the personal financial information may be displayed in the third sub-area, the chat content may be displayed in the second sub-area, and the news content may be displayed in the first sub-area.
Furthermore, embodiments of the present application also provide a computer-readable medium, comprising computer-readable instructions that when executed perform the following operations: the operations of steps S120, S140 and S160 of the method in the embodiment shown in fig. 1 described above are performed.
In summary, the method of the application can divide the display area into a plurality of sub-areas with different safety levels according to the deformation condition of the display area, and then can display the display content with corresponding safety levels in the corresponding sub-areas, thereby being beneficial to outputting the display content conveniently and safely.
Fig. 7 is a schematic structural diagram of a module of the display area dividing device according to the embodiment of the present invention, where the display area dividing device may be disposed in a flexible display device as a functional module, or the display area dividing device may also be a separate device that completes a corresponding function by communicating with a flexible display device.

The first determining module 710 is configured to determine a deformation parameter of a unit area in a display area of a display device.
The display device refers to a display device, such as a flexible display device, of which the display area can change shape. The unit area may be, for example, one display pixel, or may be a plurality of display pixels divided in advance.

Assuming that the user is always in the viewing position, i.e. on the display side of the display area, the upward, i.e. towards the user, bending downward, i.e. away from the user. Taking fig. 2 as an example, assuming that the bending portion 210 of the display area 200, i.e. the upper right corner portion in fig. 2, corresponds to a unit area, it can be seen that the deformation direction of the unit area is upward at this time.
The deformation angle refers to a degree to which the unit region is bent. Generally the bending includes two cases. One case is shown in fig. 2, in which the upwardly bent portion 210 of the unit area is a plane and the plane directly forms an angle with the main plane of the display area. This is a simple case, and the angle is the deformation angle. Alternatively, as shown in fig. 3, the curved portion of the unit area is smoothly transited, and the side view thereof is curved as shown in fig. 3, so that the deformation angle in this case is the maximum angle that the unit area is rotated. As shown in fig. 3, the deformation angle may obtain a curve as shown in the figure according to the curved surface corresponding to the unit area, then tangent lines are made at different positions of the curve, and finally a group of two tangent lines with the largest included angle is obtained, and then the included angle determined by the two tangent lines is used as the deformation angle.
In addition, it is understood by those skilled in the art that the position information of the unit area on the display area is predetermined. For convenience, the position information may be stored in correspondence with the deformation parameter. The unit area may be any unit area in the display area, and thus, the deformation parameters of all the unit areas in the display area may be obtained.
The second determining module 720 is configured to determine the safety parameter of the unit area at least according to the deformation parameter.
Referring to fig. 3, it is assumed that the point a corresponds to the first unit area and the point B corresponds to the second unit area, and the point a is shielded by the curved portion because the point a is closer to the curved portion of the display area, so that the first unit area is safer than the second unit area and can be used for displaying some more private information.
The security parameter is a parameter for reflecting the security degree of the unit area. For example, the security parameter may be defined as a number from 1 to 100, and the larger the number, the higher the security degree of the corresponding unit area.
In one embodiment, referring to fig. 8, the second determining module 720 includes:
a perpendicular line determining unit 721, configured to determine, according to the deformation parameter, a perpendicular line corresponding to the unit area, where the perpendicular line passes through a reference point of the unit area and is perpendicular to a tangent plane passing through the reference point;
an intersection point determining unit 722, configured to determine, according to deformation parameters of other unit areas in the display area, at least one intersection point between at least one plane drawn from the perpendicular line in at least one direction and the display area, where each direction corresponds to at least one intersection point;
a safety parameter determining unit 723, configured to determine the safety parameter of the unit area according to the at least one intersection corresponding to each direction and the reference point.
The reference point is a point representing the single-curved region, and may be any point on the unit region, such as a center point of the unit region. Those skilled in the art understand that, in order to determine the security parameter of each unit region more accurately, the area of the unit region should be as small as possible, i.e. the display region is divided into as many unit regions as possible, which also results in a large amount of computation.
The current shape of the unit area can be obtained according to the deformation parameters, so that a tangent plane passing through the reference point can be determined, and then the perpendicular line can be determined. The current shape of the unit area obtained according to the deformation parameter may be obtained by using the prior art, for example, the following research results may be referred to: rendl, Christian, David Kim, Senan Fanello, Patrick Parzer, Christoph Rhemann, Jonathan Taylor, Martin Zirkl "FlexSense a transparent selected-sensing deformable surface," In Proceedings of the soft 27th annual ACM symposium on User interface software and technology, pp.129-138.ACM,2014.
And if the unit area is in a plane shape, namely a non-curved surface, the tangent plane is the plane where the unit area is located.
And obtaining the current shapes of other unit areas in the display area according to the deformation parameters of the other unit areas in the display area. The at least one plane drawn from the perpendicular in at least one direction may be referred to fig. 4, where a first plane 410 represents the tangent plane, point O represents the reference point, and line L represents the perpendicular, and then a second plane 420 represents the plane drawn from the perpendicular. Assuming that the direction indicated by the straight arrow in fig. 4 is the initial direction, the second plane 420 can rotate around the vertical line along the curved arrow in the figure, and can rotate up to 360 degrees. Therefore, the at least one direction can be represented by an included angle between the at least one plane and an initial direction, and the value of the included angle is between 0 and 360 degrees. That is to say, each direction corresponds to a plane drawn from the perpendicular, and the number of the planes may be set according to the required precision, for example, one plane may be drawn at intervals of 1 degree, so that 360 planes are drawn in total.
It is understood by those skilled in the art that each of the planes has an infinite number of intersections with the display area, and for simplicity, the intersection of the plane with each unit area within the display area can be reduced to a reference point for that unit area. That is, if the plane intersects with one unit area, the reference point of the unit area is taken as the intersection of the plane and the unit area. As shown in fig. 5, the plane to be bent represents the display area 510, each cell on the plane represents a unit area, the straight line L represents a perpendicular line passing through the reference point O of the first unit area 511, and the plane to the right of the perpendicular line represents a plane 520 drawn from the perpendicular line, assuming that the current corresponding direction of the plane 520 is the initial direction. The plane 520 intersects the display area 510 to form an intersection line indicated by a black and thick line in fig. 5. The intersection line includes P, Q, R, S, T, U, V, W a series of intersections, which are reference points of the second unit area 512, the third unit area 513, the fourth unit area 514, the fifth unit area 515, the sixth unit area 516, the seventh unit area 517, the eighth unit area 518, and the ninth unit area 519, respectively. That is, the series of intersection points P, Q, R, S, T, U, V, W are the intersection points corresponding to the initial direction. Similarly, the intersection points corresponding to other directions can be obtained by rotating the plane 520 around the vertical line.
In one embodiment, referring to fig. 8, the security parameter determination unit 723 includes:
a target included angle determining subunit 7231, configured to determine a smallest included angle of at least one included angle as a target included angle corresponding to a first direction, where the at least one included angle is an included angle between at least one connection line and the vertical line, the at least one connection line is a connection line between at least one intersection corresponding to the first direction and the reference point, and the first direction is any one of the at least one direction;
a safety parameter determining subunit 7232, configured to determine the safety parameters of the unit area according to at least one target included angle respectively corresponding to the at least one direction.
For clarity, the intersection points on the perpendicular lines, the intersecting lines and the intersecting lines in fig. 5 are extracted to obtain a simplified diagram as shown in fig. 6. It can be seen that the intersection points P, Q, R, S, T, U, V, W are sequentially connected to the reference point O to obtain a connection line between at least one intersection point corresponding to the initial direction and the reference point O, and these connection lines form a series of included angles with the straight line L, and as can be seen from fig. 5, the angle β is the smallest included angle in the series of included angles, that is, the target included angle corresponding to the initial direction. The first direction is any one of the at least one direction, and therefore, the angle β can be considered as a target included angle corresponding to the first direction.
Similarly, the target included angles corresponding to other directions can be obtained. Assuming that the unit area is not located at the edge of the display area, a number of target angles equal to the number of the at least one direction is finally obtained, and assuming that a total of 360 directions, 360 corresponding target angles are obtained. If the unit area is at the edge of the display area, there will be no corresponding target angle in some directions.
In an embodiment, the safety parameter determining subunit 7232 is configured to determine the safety parameter of the unit area according to an average value of at least one target included angle respectively corresponding to the at least one direction. For example, 360 target included angles are summed and averaged, and the safety parameter of the unit area is determined according to the average value. Those skilled in the art will appreciate that the smaller the average value, the more the unit area is occluded, and the higher the security level, and accordingly, the higher the value of the security parameter may be.
In addition, if the number of the at least one direction is fixed, the safety parameter of the unit area can also be directly determined according to the angle sum of the at least one target included angle respectively corresponding to the at least one direction.
It will be appreciated by those skilled in the art that the security parameters for all unit areas within the display area can be derived in accordance with the principles described above.
The third determining module 730 is configured to determine a sub-region to which the unit region belongs and a security level of the sub-region at least according to the security parameter, where the display region includes the sub-region.
In one embodiment, referring to fig. 9, the third determining module 730 includes:
a clustering unit 731, configured to perform clustering on the unit area and other unit areas in the display area according to the security parameter and the security parameters of other unit areas in the display area;
a safety level determining unit 732, configured to determine the sub-area to which the unit area belongs and the safety level of the sub-area according to the processing result.
And performing clustering processing on the unit area and other unit areas in the display area, namely performing clustering processing on all the unit areas in the display area. The result of the clustering process is to divide the unit areas with the same or close safety parameters into one sub-area. In practical applications, the number of the sub-regions into which the display region is divided may be set according to requirements. For example, assuming that it is required to divide the display area into 4 sub-areas, the result of the clustering process is to divide all the unit areas into 4 classes, and the unit areas in each class are continuous.
The safety level is used to reflect the safety degree of the sub-region, and generally, the higher the value of the safety parameter of a unit region in the sub-region is, the higher the safety level of the sub-region is.
In one embodiment, referring to fig. 10, the apparatus 700 further comprises:
a display module 740, configured to display corresponding display content corresponding to the security level of the sub-region.
In practical applications, the content to be displayed may be marked with a security level, and then the displayed content with the same security level as that of the sub-area may be displayed in the sub-area. For example, assume that the display area includes three sub-areas: the safety levels of the first sub-area, the second sub-area and the third sub-area are 1, 2 and 3 in sequence; if the corresponding display content comprises personal financial information, chat content and news content, the security level of the personal financial information can be marked as 3, the security level of the chat content is 2, and the security level of the news content is 1; the personal financial information may be displayed in the third sub-area, the chat content may be displayed in the second sub-area, and the news content may be displayed in the first sub-area.
In summary, the device described in the present application can divide the display area into a plurality of sub-areas with different security levels according to the deformation condition of the display area, and then can display the display content with corresponding security levels in the corresponding sub-areas, thereby facilitating the convenient and safe output of the display content.
