[0047] The technical solution of the present invention is further elaborated in detail below in conjunction with the accompanying drawings and specific embodiments of the specification. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the technical field of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0048] See also Figure 1 , a display area adjustment method provided by an embodiment of the present invention is applied in a terminal, and the display area adjustment method includes the following steps:

[0049] Step S101: The terminal turns on the one-handed mode and obtains the user's fingerprint information;

[0050] It should be noted that the terminal can be a mobile terminal device with adjustable display area, such as a smart phone, a personal digital assistant, a tablet computer, or a fixed terminal device with adjustable display area, such as a desktop computer. Here, a one-handed mode is set in the terminal. In the one-handed mode, the terminal can adjust the display area according to the user's fingerprint information, so that the user can conveniently control the display area of ​​the terminal with one hand. In one embodiment, before turning on the one-handed mode, it also includes: when the user's fingerprint is detected, the coverage time of the fingerprint is monitored; when the coverage time reaches a preset time threshold, the step of turning on the one-handed mode is executed. Specifically, when the terminal detects the user's fingerprint, the coverage time of the fingerprint is counted, and when the coverage time is equal to or greater than the preset time threshold, the one-handed mode is turned on. The coverage time of the fingerprint indicates the length of time that the finger contacts or covers the fingerprint recognition area of ​​the terminal, and only when the coverage time of the fingerprint is greater than the preset time threshold, it means that the user may really need to start the function of adjusting the display area of ​​the terminal with one hand, which can avoid the user accidentally touching or clicking the fingerprint recognition area and inputting the fingerprint into the terminal. The one-handed mode is turned on by mistake. The preset time threshold can be set according to actual needs, for example, it can be set to 1 second to 10 seconds, specifically 2 seconds, 4 seconds, etc. In this way, the one-handed mode is turned on only when the fingerprint coverage time is greater than the preset time threshold, which can effectively avoid the false triggering operation of adjusting the display area and improve the user experience. In addition, the terminal can be provided with a one-handed mode switch button. By switching the switch button, the one-handed mode can be turned on or off, so that the terminal can detect whether the one-handed mode is in the on state.

[0051] It can be understood that in order to facilitate the left hand and the right hand to control the display area separately, and to facilitate the distinction between the left hand and the right hand, the single-handed mode may include a left-handed single-handed mode and a right-handed single-handed mode, the left-handed single-handed mode refers to a mode in which the display area is controlled by the left hand, and the right-handed single-handed mode refers to a mode in which the display area is controlled by the right hand, and the left-handed single-handed mode and the right-handed single-handed mode can be distinguished by fingerprints, that is, which single-handed mode is turned on according to the user's fingerprint detection. In other words, the permission fingerprint for turning on the left-handed single-handed mode and the permission fingerprint for turning on the right-handed single-handed mode can be pre-set. In one embodiment, before turning on the single-handed mode, it may also include: after receiving an instruction to enter the permission fingerprint, prompting whether to set the permission fingerprint of the left-handed single-handed mode or the right-handed single-handed mode; when determining to set the permission fingerprint of the left-handed single-handed mode, setting the entered fingerprint as the permission fingerprint of the left-handed single-handed mode; when determining to set the permission fingerprint of the right-handed single-handed mode, setting the entered fingerprint as the permission fingerprint of the right-handed single-handed mode. Here, the terminal may be provided with a setting interface for the permission fingerprint for turning on the one-handed mode. When the user clicks the permission fingerprint setting button in the setting interface, it is equivalent to the terminal receiving an instruction to enter the permission fingerprint. At this time, the terminal may prompt whether to set the permission fingerprint for the left-handed one-handed mode or the right-handed one-handed mode, and after the user selects the category of the permission fingerprint to be entered, the user may be prompted to enter the fingerprint through the fingerprint recognition area. In addition, the terminal may also prompt the user whether to enter the fingerprint of the thumb so that the fingerprint of the thumb is used as the permission fingerprint. In this way, by providing an entry operation for the permission fingerprint for turning on different one-handed modes, it is convenient for users to flexibly set the permission fingerprint, further improving the user experience. Accordingly, in one embodiment, turning on the one-handed mode includes: identifying the detected fingerprint of the user, and determining whether to turn on the left-handed one-handed mode or the right-handed one-handed mode according to the identification result. Specifically, the terminal identifies the detected fingerprint of the user, that is, compares the fingerprint with the permission fingerprint of the left-handed single-handed mode and the permission fingerprint of the right-handed single-handed mode, respectively, to determine whether the fingerprint is matched as the permission fingerprint of the left-handed single-handed mode or the permission fingerprint of the right-handed single-handed mode, thereby deciding to turn on the left-handed single-handed mode or the right-handed single-handed mode accordingly.

[0052] Here, the terminal has a fingerprint recognition module, and the fingerprint recognition module can specifically provide the user with a corresponding fingerprint recognition function in the form of a fingerprint recognition area. The fingerprint recognition area can be integrated on the touch screen of the terminal or can be separately set on the back of the screen of the terminal. In practical applications, the fingerprint recognition module can be a device that can provide a fingerprint recognition function, such as a fingerprint sensor. When the user touches, covers or clicks the fingerprint recognition area of ​​the terminal with a finger, the terminal obtains the corresponding fingerprint information by detecting the contact, cover or click operation of the finger in the fingerprint recognition area. The terminal obtains the fingerprint information of the user, which can be the terminal obtaining the fingerprint information of the user in real time or periodically obtaining the fingerprint information of the user at a set time interval. The fingerprint information of the user can be the fingerprint information of the user at a certain moment or at different moments. The fingerprint information may include information such as the image of the fingerprint, the corresponding fingerprint coverage area, and the fingerprint coverage center point. In one embodiment, the acquisition of the fingerprint information of the user includes: when the single-handed mode is turned on, the initial fingerprint information is acquired and saved; when the fingerprint is detected to have changed, the changed fingerprint information is acquired. Specifically, the terminal obtains the fingerprint information corresponding to when the one-handed mode is turned on, and uses the fingerprint information obtained at this time as the initial fingerprint information, and when the fingerprint is detected to have changed, the fingerprint information at this time is obtained as the changed fingerprint information. It should be noted that the initial fingerprint information and the changed fingerprint information can be fingerprints continuously input by the same finger without leaving the fingerprint recognition area, and the difference exists only because the contact area between the finger and the fingerprint recognition area changes. For example, the initial fingerprint information can be generated by the thumb of the user's right hand contacting the fingerprint recognition area, and the changed fingerprint information can be generated by the thumb of the user's right hand contacting the fingerprint recognition area, that is, on the basis of generating the initial fingerprint information, and the contact area with the fingerprint recognition area changes due to lifting forward or backward. Of course, the initial fingerprint information and the changed fingerprint information can also be fingerprint information input by different fingers. Here, the detection of the fingerprint change can be when it is detected that the currently collected fingerprint information is different from the initial fingerprint information, so that the currently collected fingerprint information is used as the changed fingerprint information, and the changed fingerprint information contains part of the feature information in the initial fingerprint information. In this way, after the initial fingerprint information is obtained, the changed fingerprint information is obtained when the fingerprint changes, so as to accurately know the fingerprint change information.

[0053] Step S102: the terminal adjusts the display area according to the fingerprint information;

[0054] Specifically, the terminal adjusts the display area according to the fingerprint information obtained in step S101.

[0055] Here, the terminal adjusts the display area according to the fingerprint information, which may be the terminal adjusting the display area according to the change direction of the fingerprint. In addition, the terminal adjusts the display area according to the fingerprint information, which may be the terminal determining the position of the fingerprint in the fingerprint recognition area according to the fingerprint information, and adjusting the display area according to the set adjustment instruction corresponding to the position. In one embodiment, the terminal adjusts the display area according to the fingerprint information, including: determining the change direction of the fingerprint according to the initial fingerprint information and the changed fingerprint information; adjusting the display area according to the change direction of the fingerprint. It can be understood that the change trend of the fingerprint can be obtained according to the initial fingerprint information and the changed fingerprint information, such as the change in the size of the fingerprint coverage area, the change in the position of the fingerprint coverage center point, etc., so that the change direction of the fingerprint can be obtained according to the change trend of the fingerprint. For different change directions of the fingerprint, corresponding adjustment instructions can be set respectively, so that the display area is adjusted according to the adjustment instruction corresponding to the change direction of the fingerprint.

[0056] Here, the change direction of the fingerprint can be used to characterize the change position of the fingerprint, that is, it can be used to characterize the change state of the finger. In one embodiment, the change direction of the fingerprint is determined based on the initial fingerprint information and the changed fingerprint information, including: determining the initial fingerprint coverage center point based on the initial fingerprint information; dividing the pattern corresponding to the initial fingerprint information into several areas according to a set area division method with the initial fingerprint coverage center point as the center; obtaining the area occupied by the fingerprint in each area after the change according to the changed fingerprint information, and determining the change direction of the fingerprint according to the area occupied by the fingerprint in each area after the change. Here, the determining of the initial fingerprint coverage center point according to the initial fingerprint information may be to obtain the first tangent of the upper edge, the second tangent of the lower edge, the third tangent of the left edge, and the fourth tangent of the right edge of the pattern corresponding to the initial fingerprint information respectively according to the initial fingerprint information, and then use the intersection between the connecting line from the first intersection point to the third intersection point and the connecting line from the second intersection point to the fourth intersection point as the initial fingerprint coverage center point, the first intersection point is the intersection point between the first tangent line and the third tangent line, the second intersection point is the intersection point between the first tangent line and the fourth tangent line, the third intersection point is the intersection point between the fourth tangent line and the second tangent line, and the fourth intersection point is the intersection point between the second tangent line and the third tangent line. The dividing of the pattern corresponding to the initial fingerprint information into a plurality of regions according to a set region division method with the initial fingerprint coverage center point as the center and the orientation of the fingerprint as the reference direction or the normal up, down, left, and right as the reference direction may include dividing the pattern corresponding to the initial fingerprint information into a plurality of regions according to a set region division method with the initial fingerprint coverage center point as the center and the orientation of the fingerprint as the reference direction or the normal up, down, left, and right as the reference direction. The orientation of the fingerprint refers to the direction of the corresponding fingertip when the fingerprint is recorded. When the finger contacts the fingerprint recognition area from different directions, that is, the fingerprint recording direction is different, the orientation of the fingerprint is also different. The pattern corresponding to the initial fingerprint information is divided into a plurality of areas according to the set area division method, which can be to divide the pattern corresponding to the initial fingerprint information into two upper and lower areas, or to divide the pattern corresponding to the initial fingerprint information into two left and right areas, or to divide the fingerprint into four areas of upper right, lower right, upper left and lower left. If the fingerprint is divided into four areas: upper right, lower right, upper left, and lower left, then the pattern corresponding to the initial fingerprint information is divided into several areas according to the set area division method, with the initial fingerprint coverage center point as the center and the fingerprint orientation as the reference direction. This is equivalent to taking the initial fingerprint coverage center point as the origin and constructing a rectangular coordinate system with the fingerprint orientation as the positive direction of the Y-axis. Therefore, according to the changed fingerprint information, the area occupied by the fingerprint in each quadrant of the rectangular coordinate system after the change can be correspondingly known, that is, the area occupied by the fingerprint in each area after the change is determined according to the changed fingerprint information.Since the area occupied by the fingerprint in each region after the change is related to the direction of the finger, the change direction of the fingerprint can be determined according to the size of the area occupied in each region. For example, if it is determined based on the changed fingerprint information that the fingerprint is basically in the first and second quadrants of the above-mentioned rectangular coordinate system after the change, it means that the fingerprint is basically in the upper half of the pattern corresponding to the initial fingerprint information after the change, the finger is upward, and the change direction of the fingerprint is upward. In this way, by taking the initial fingerprint coverage center point as the center, the pattern corresponding to the initial fingerprint information is divided into several regions according to the set area division method to accurately determine the change direction of the fingerprint, which can improve the accuracy of adjusting the display area. In addition, determining the changing direction of the fingerprint based on the initial fingerprint information and the changed fingerprint information may also be: determining the initial fingerprint coverage center point based on the initial fingerprint information and determining the changed fingerprint coverage center point based on the changed fingerprint information; dividing the pattern corresponding to the initial fingerprint information into several areas according to a set area division method with the initial fingerprint coverage center point as the center and the orientation of the fingerprint as the reference direction; obtaining the changing direction of the fingerprint based on the area where the changed fingerprint coverage center point is located.

[0057] In one embodiment, the determining the change direction of the fingerprint according to the area occupied by each region after the fingerprint changes includes: obtaining the target region corresponding to the minimum area according to the area occupied by each region after the fingerprint changes; and taking the opposite direction of the direction represented by the target region as the change direction of the fingerprint. Here, after knowing the area occupied by each region after the fingerprint changes according to the changed fingerprint information, the target region corresponding to the minimum area can be determined. Since the target region is obtained by dividing the pattern corresponding to the initial fingerprint information according to the set area division method, the position of the target region in the pattern corresponding to the initial fingerprint information can be obtained, that is, the direction represented by the target region. Here, determining the change direction of the fingerprint according to the area occupied by each region after the fingerprint changes can also be to obtain the region corresponding to the maximum area according to the area occupied by each region after the fingerprint changes, and taking the direction represented by the region corresponding to the maximum area as the change direction of the fingerprint. Assuming that the pattern corresponding to the initial fingerprint information is divided into two areas, upper and lower, and the target area is the lower area, since the target area is in the lower half of the fingerprint, that is, most of the fingerprint is in the upper half of the pattern after the change, it can be determined that the change direction of the fingerprint is upward. It can be understood that when the pattern corresponding to the initial fingerprint information is divided into two areas, upper and lower, or the pattern corresponding to the initial fingerprint information is divided into two areas, left and right, if during the process of recording the fingerprint, the contact area between the finger and the fingerprint recognition area changes less or the recognition accuracy is not high, it may not be easy to accurately determine the change direction of the fingerprint directly through the position of the area corresponding to the maximum area in the pattern, and it may be easier to accurately determine the change direction of the fingerprint indirectly through the position of the target area corresponding to the minimum area in the pattern. In this way, by accurately determining the change direction of the fingerprint, the accuracy of adjusting the display area can be improved.

[0058] It should be noted that the adjustment of the display area may be to adjust the size of the display area, such as to enlarge or reduce the display area, or to move the position of the display area, such as to move the display area to the left or to the right. The display area may refer to the display interface of the terminal screen, or may refer to a display window displayed on the terminal screen, which is used to display the working interface of the application. The adjustment of the display area according to the fingerprint information may be regarded as adjusting the display area according to the adjustment instruction corresponding to the change direction of the fingerprint. The adjustment instruction corresponding to the change direction of the fingerprint may be pre-set according to actual needs. For example, when the change direction of the fingerprint is upward, the corresponding adjustment instruction may be set as an enlargement instruction; when the change direction of the fingerprint is downward, the corresponding adjustment instruction may be set as a reduction instruction. Here, the adjustment instruction may correspond to different scaling parameters set. For example, the enlargement instruction may be to enlarge the display area by 0.5 times, 1 times, etc., and the reduction instruction may be to reduce the display area by 0.5 times, 1 times, etc. Therefore, the terminal adjusts the display area according to the set adjustment instruction corresponding to the change direction of the fingerprint, which may be that the terminal adjusts the display area according to the set scaling or magnification ratio parameter corresponding to the change direction of the fingerprint.

[0059] In summary, in the display area adjustment method provided in the above embodiment, the terminal turns on the one-handed mode, obtains the user's fingerprint information, and adjusts the display area according to the fingerprint information. In this way, the terminal obtains the user's fingerprint information in the one-handed mode, and automatically adjusts the display area according to the fingerprint information, so that the user can conveniently control the display area of ​​the terminal with one hand, thereby improving the user experience.

[0060] In one implementation, adjusting the display area according to the fingerprint information includes:

[0061] Acquiring an initial fingerprint coverage area according to the initial fingerprint information and acquiring a changed fingerprint coverage area according to the changed fingerprint information;

[0062] When the changed fingerprint coverage area is equal to or greater than a preset threshold of the initial fingerprint coverage area, performing the step of adjusting the display area according to the change direction of the fingerprint;

[0063] When the changed fingerprint coverage area is smaller than a preset threshold of the initial fingerprint coverage area, the adjustment of the display area is terminated.

[0064] Specifically, after the terminal obtains the fingerprint information, it obtains the initial fingerprint coverage area according to the initial fingerprint information and obtains the changed fingerprint coverage area according to the changed fingerprint information, and determines whether the changed fingerprint coverage area is equal to or greater than the preset threshold of the initial fingerprint coverage area. If so, it is allowed to adjust the display area according to the change direction of the fingerprint, otherwise it is not allowed to adjust the display area according to the change direction of the fingerprint, that is, the one-handed mode is terminated. It can be understood that after the user enters the fingerprint in the fingerprint recognition area, if the user does not need to adjust the display area temporarily, the finger can be controlled to quickly leave the fingerprint recognition area or one side of the finger can be quickly lifted to make the changed fingerprint coverage area as small as possible. At this time, the terminal only allows the display area to be adjusted when it detects that the changed fingerprint coverage area is equal to or greater than the preset threshold of the initial fingerprint coverage area. The preset threshold can be set according to the actual needs, such as one-half, two-fifths, etc. In this way, the display area can be flexibly controlled to be adjusted according to the needs of the user, further improving the user experience.

[0065] In one embodiment, the one-hand mode includes a left-hand one-hand mode and a right-hand one-hand mode, and before adjusting the display area according to the fingerprint information, the method further includes:

[0066] When the one-handed mode is the left-handed one-handed mode, displaying a preset adjustment box on the left side of the screen of the terminal;

[0067] When the one-handed mode is the right-handed mode, a preset adjustment box is displayed on the right side of the screen of the terminal.

[0068] Here, the one-handed mode includes a left-handed one-handed mode and a right-handed one-handed mode to distinguish the way of operating the terminal with one hand. Since the authority fingerprints corresponding to the left-handed one-handed mode and the right-handed one-handed mode can be set respectively, the type of the currently turned-on one-handed mode can be determined by identifying the acquired fingerprint. When the one-handed mode is the left-handed one-handed mode, it means that the left hand is currently used to adjust the display area of ​​the terminal, and when the one-handed mode is the right-handed one-handed mode, it means that the right hand is currently used to adjust the display area of ​​the terminal. At this time, according to the type of the one-handed mode, a preset adjustment box can be displayed at different preset positions on the screen of the terminal, so as to remind the user of the current way of operating the terminal and the adjustment instructions used, so as to facilitate the user to obtain relevant information in time. The displaying of the preset adjustment box on the left side of the screen of the terminal can be a displaying of the preset adjustment box at a first preset position on the left side of the screen of the terminal, and the displaying of the preset adjustment box on the right side of the screen of the terminal can be a displaying of the preset adjustment box at a second preset position on the right side of the screen of the terminal. The first preset position and the second preset position can be set according to actual needs. For example, the first preset position can be the lower left corner, and the second preset position can be the lower right corner. When the preset adjustment box appears in the lower left corner of the terminal screen, it indicates that the user is adjusting the display area of ​​the terminal by operating the terminal with the left hand. In this way, the preset adjustment box is displayed at different positions on the terminal screen according to different one-handed modes, which enhances the user experience and further improves the user experience.

[0069] In one embodiment, the one-hand mode includes a left-hand one-hand mode and a right-hand one-hand mode, and the adjusting the display area according to the change direction of the fingerprint includes:

[0070] When the one-hand mode is the left-hand one-hand mode and the adjustment instruction corresponding to the change direction of the fingerprint is a reduction instruction, the display area is reduced toward the lower left corner of the screen of the terminal;

[0071] When the one-hand mode is the left-hand one-hand mode and the adjustment instruction corresponding to the change direction of the fingerprint is a zoom-in instruction, zooming in the display area toward the upper right corner of the screen of the terminal;

[0072] When the one-hand mode is the right-hand one-hand mode and the adjustment instruction corresponding to the change direction of the fingerprint is a reduction instruction, the display area is reduced toward the lower right corner of the screen of the terminal;

[0073] When the single-hand mode is the right-hand single-hand mode, and the adjustment instruction corresponding to the change direction of the fingerprint is a zoom-in instruction, the display area is zoomed in toward the upper left corner of the screen of the terminal.

[0074] In this way, the display area is adjusted accordingly according to the one-handed mode and the adjustment instructions corresponding to the changing direction of the fingerprint, which increases the operation diversity and further improves the user experience.

[0075] In one embodiment, after adjusting the display area according to the fingerprint information, the method may further include: when the user's fingerprint is not detected, the adjustment of the display area is terminated. Specifically, in the process of adjusting the display area according to the fingerprint information, the terminal determines in real time whether the user's fingerprint is detected. If not, the display area is stopped from being adjusted; if so, the display area is continued to be adjusted according to the fingerprint information. Here, the process of adjusting the display area according to the fingerprint information may be a gradual and continuous adjustment process, such as gradually enlarging or reducing the display area. It can be understood that in the process of adjusting the display area according to the fingerprint information, if the user believes that the display area does not need to be adjusted at a certain moment according to the adjusted display area, the finger can be controlled to leave the fingerprint recognition area so that the terminal cannot detect the user's fingerprint, and the terminal can stop adjusting the display area at this time. In this way, whether to adjust the display area is flexibly determined according to whether the user's fingerprint is detected, which further improves the user experience.

[0076] Based on the same inventive concept as the above embodiments, this embodiment describes the technical solution of the above embodiments in detail through specific examples. In this embodiment, the terminal is a mobile phone, the first authority fingerprint is the thumb fingerprint of the left hand and corresponds to the left hand single-handed mode, and the second authority fingerprint is the thumb fingerprint of the right hand and corresponds to the right hand single-handed mode. Figure 2 A specific flow chart of a method for adjusting a display area provided by an embodiment of the present invention includes the following steps:

[0077] Step S201: The mobile phone detects that a thumb covers the fingerprint sensor for a long time;

[0078] Here, when the mobile phone detects that a thumb covers the fingerprint sensor, it starts timing, and determines whether the thumb covers the fingerprint sensor for a long time based on whether the timing time reaches the preset time threshold. That is, when the timing time reaches the preset time threshold, it means that the thumb covers the fingerprint sensor for a long time. When the timing time does not reach the preset time threshold, it means that the thumb does not cover the fingerprint sensor for a long time.

[0079] Step S202: Identify the type of the thumb, and enable the corresponding one-handed mode according to the type of the thumb;

[0080] Specifically, after the mobile phone detects that a thumb covers the fingerprint sensor for a long time, it indicates that the display area of ​​the mobile phone is allowed to be adjusted. The type of thumb is then identified. If the thumb is identified as the left thumb, the left-handed mode is turned on; if the thumb is identified as the right thumb, the right-handed mode is turned on.

[0081] Here, before the thumb type is identified, the thumb fingerprint may be recorded to set the corresponding one-handed mode according to the recorded thumb type. Specifically, when recording the corresponding fingerprint for different one-handed modes, the user may be asked whether to record the thumb fingerprint. If so, the user is prompted to select whether the currently recorded thumb fingerprint is the left thumb or the right thumb. If the user determines that the currently recorded thumb fingerprint is the left thumb, the left thumb fingerprint is set as the permission fingerprint for opening the left-hand one-handed mode, that is, a binding relationship between the left-hand one-handed mode and the left thumb fingerprint is established; if the user determines that the currently recorded thumb fingerprint is the right thumb, the right thumb fingerprint is set as the permission fingerprint for opening the right-hand one-handed mode, that is, a binding relationship between the right-hand one-handed mode and the right thumb fingerprint is established.

[0082] It should be noted that when the left-handed one-handed mode is turned on, a preset adjustment box may be displayed in the lower left corner of the phone's screen, informing the user that the phone's display area will be adjusted through the left-handed one-handed mode; when the right-handed one-handed mode is turned on, a preset adjustment box may be displayed in the lower right corner of the phone's screen, informing the user that the phone's display area will be adjusted through the right-handed one-handed mode.

[0083] Step S203: obtaining the center point of the fingerprint of the thumb and the corresponding coverage area S1;

[0084] Step S204: when it is found that the current fingerprint is missing in a certain direction relative to the fingerprint of the thumb, the fingerprint of the thumb is cut into two parts according to the center point;

[0085] Here, due to the tilting of the user's finger and other operations, the fingerprint of the thumb in the current fingerprint will be missing in a certain direction, so the fingerprint of the thumb is cut into two parts with the center position of the fingerprint of the thumb as the center point. In this embodiment, cutting the fingerprint of the thumb into upper and lower parts is taken as an example.

[0086] Step S205: when it is detected that the current coverage area S2 remains more than half of S1, the portion with the largest area shortage is determined;

[0087] Step S206: taking the opposite direction of the part with the largest area loss as the tilt direction of the user's finger;

[0088] Here, if the part with the largest area missing is the lower half, the tilt direction of the user's finger is forward; if the part with the largest area missing is the upper half, the tilt direction of the user's finger is backward.

[0089] Step S207: adjusting the display area according to the tilt direction of the user's finger and the corresponding one-handed mode.

[0090] Specifically, when the user's finger is tilted forward and the corresponding one-handed mode is the left-handed mode, the display area is reduced toward the lower left corner; when the user's finger is tilted backward and the corresponding one-handed mode is the left-handed mode, the display area is enlarged toward the lower left corner; when the user's finger is tilted forward and the corresponding one-handed mode is the right-handed mode, the display area is reduced toward the lower right corner; when the user's finger is tilted backward and the corresponding one-handed mode is the right-handed mode, the display area is enlarged toward the lower right corner. Finally, when the user's finger leaves the fingerprint recognition area, the size of the display area is determined and no longer adjusted. Assume that the information of the fingerprint generated when the user's thumb covers the fingerprint recognition area is recorded as the first information, and the information of the fingerprint generated when the user's thumb is tilted up or down after covering the fingerprint recognition area is recorded as the second information, please refer to Figure 3 , is a schematic diagram of the fingerprint position change, Figure 3 (a) is a schematic diagram showing the position of the corresponding fingerprint when the user's thumb covers the fingerprint recognition area. Figure 3 (b) is a schematic diagram showing the position of the corresponding fingerprint when the user's thumb covers the fingerprint recognition area and then moves upward. Figure 3 (c) is a schematic diagram showing the position of the corresponding fingerprint when the user's thumb covers the fingerprint recognition area and then tilts downward. It can be seen from the above figure that when the user's thumb covers the fingerprint recognition area, the fingerprint of the thumb basically covers the entire fingerprint recognition area. At this time, if the thumb tilts upward, the fingerprint corresponding to the thumb is mostly located in its upper half, and if the thumb tilts downward, the fingerprint corresponding to the thumb is mostly located in its lower half. Assume that the one-handed mode turned on at this time is the left-handed one-handed mode, that is, Figure 3 The fingerprint in (a) is the thumb fingerprint of the left hand, and when the thumb is tilted upward, the corresponding adjustment instruction is an instruction to enlarge to the lower left corner, while when the thumb is tilted downward, the corresponding adjustment instruction is an instruction to reduce to the lower left corner. Please refer to Figure 4 , is a schematic diagram of the display area change, where the diagonal box part represents the display area, Figure 4 (a) is a schematic diagram showing the display area before adjustment. Figure 4 (b) is a schematic diagram showing the display area after being enlarged to the lower left corner. Figure 4 (c) is a schematic diagram showing the display area being reduced to the lower left corner. Figure 4It can be seen that in the left-handed single-hand mode, when the thumb fingerprint of the user's left hand is tilted upward, the display area is enlarged toward the lower left corner, and when the thumb fingerprint of the user's left hand is tilted downward, the display area is reduced toward the lower left corner.

[0091] In summary, the above display area adjustment method can conveniently adjust the size of the display area through fingerprints, making it convenient for users to adjust the display area with one hand.

[0092] See also Figure 5 , another display area adjustment method provided by an embodiment of the present invention is applied to a device having a first display area and a second display area, and the display area adjustment method includes the following steps:

[0093] Step S301: when a first display area is displayed on the device, obtaining first fingerprint information of a user;

[0094] Step S302: comparing the first fingerprint information with a preset fingerprint information;

[0095] Step S303: adjusting the first display area to the second display area according to the changes of the two.

[0096] Specifically, when the first display area is displayed on the device, the first fingerprint information of the user is obtained, the first fingerprint information is compared with a preset fingerprint information, and according to the change between the two, the first display area is adjusted to the second display area.

[0097] Here, the adjustment of the first display area to the second display area according to the change of the two may be that when it is detected that the similarity between the first fingerprint information and the preset fingerprint information is greater than the preset similarity threshold, the first display area is adjusted to the second display area. The adjustment of the first display area to the second display area according to the change of the two may be that when it is detected that the change direction of the fingerprint is the preset direction, the first display area is adjusted to the second display area. It should be noted that a fingerprint coverage center point can be determined according to the preset fingerprint information, and the pattern corresponding to the preset fingerprint information can be divided into several areas according to the set area division method with the fingerprint coverage center point as the center, and the area occupied by the first fingerprint information in each of the areas is obtained according to the first fingerprint information, and the change direction of the fingerprint is determined according to the area occupied by the first fingerprint information in each of the areas. Taking the preset direction as upward as an example, when it is detected that the change direction of the first fingerprint information relative to the preset fingerprint information is upward, the first display area is adjusted to the second display area.

[0098] In one embodiment, the first display area and the second display area have different areas on the device, for example, the first display area may be three sixths of the overall display area of ​​the device, and the second display area may be two sixths of the overall display area of ​​the device, etc. In this way, different display areas have different areas on the device, which is convenient for users to use flexibly.

[0099] In one embodiment, the first display area and the second display area partially or non-overlappingly displayed on the device. For example, the first display area and the second display area may be half of the overall display area of ​​the device respectively.

[0100] In one embodiment, the first display area and the second display area are part of the overall display area of ​​the device, and are displayed on the device when the first display area is different from the second display area.

[0101] In summary, in the display area adjustment method provided in the above embodiment, when the first display area is displayed on the device, the user's first fingerprint information is obtained, and according to the change between the first fingerprint information and the preset fingerprint information, the first display area is adjusted to the second display area. In this way, the display area is automatically adjusted according to the fingerprint information, so that the user can conveniently adjust the display area of ​​the terminal, thereby improving the user experience.

[0102] Based on the same inventive concept as the embodiment, an embodiment of the present invention provides a method for adjusting a display area, which is applied to a device having a first display area, where the first display area is part or all of the display area of ​​the device, and the method for adjusting the display area includes:

[0103] When fingerprint information of the user at different times is received, the area range or direction of the first display area is adjusted according to changes in different fingerprint information.

[0104] Specifically, fingerprint information input by the user at different times is received to obtain different fingerprint information, and the area range of the first display area is adjusted according to the changes of the different fingerprint information; or, fingerprint information input by the user at different times is received to obtain different fingerprint information, and the direction of the first display area is adjusted according to the changes of the different fingerprint information.

[0105] Here, the adjustment of the area range or direction of the first display area according to the change of different fingerprint information may be the adjustment of the area range or direction of the first display area according to the change direction of different fingerprint information. It can be understood that the change trend of the fingerprint can be known according to different fingerprint information, such as the change of the size of the fingerprint coverage area, the change of the position of the fingerprint coverage center point, etc., so that the change direction of the fingerprint can be known according to the change trend of the fingerprint. For different change directions of the fingerprint, corresponding adjustment instructions can be set respectively, so that the area range or direction of the first display area is adjusted according to the adjustment instructions corresponding to the change direction of the fingerprint. Here, the change direction of the fingerprint can be used to characterize the change position of the fingerprint, that is, it can be used to characterize the change state of the finger. It should be noted that the initial fingerprint coverage center point can be determined according to an initial fingerprint information, and the pattern corresponding to the initial fingerprint information can be divided into several areas according to the set area division method with the initial fingerprint coverage center point as the center, and the area occupied by the subsequent input fingerprint information in each of the areas is obtained according to the subsequent input fingerprint information, and the change direction of the fingerprint is determined according to the area occupied by the subsequent input fingerprint information in each of the areas. It should be noted that the adjustment of the area range of the first display area may be to enlarge or reduce the area range of the first display area, etc. The direction of adjusting the first display area may be to move the first display area to the left or to the right, etc. The adjustment instruction corresponding to the direction of fingerprint change may be pre-set according to actual needs. For example, when the direction of fingerprint change is upward, the corresponding adjustment instruction may be set to enlarge the area range of the first display area; when the direction of fingerprint change is downward, the corresponding adjustment instruction may be set to reduce the area range of the first display area. Alternatively, when the direction of fingerprint change is upward, the corresponding adjustment instruction may be set to move the first display area to the left; when the direction of fingerprint change is downward, the corresponding adjustment instruction may be set to move the first display area to the right, etc.

[0106] In summary, in the display area adjustment method provided in the above embodiment, the area range or direction of the first display area is adjusted according to the changes of different fingerprint information input by the user at different times. In this way, the display area is automatically adjusted according to the fingerprint information, so that the user can conveniently adjust the display area of ​​the terminal, thereby improving the user experience.
