Fig. 2A is a flowchart of another screen display method according to an embodiment of the present invention, which is applied to a terminal, and referring to fig. 2A, the method specifically includes the following steps.
Step 201: when the deformation operation aiming at the display screen of the terminal is detected, the deformation parameter corresponding to the deformation operation is determined, and the deformation parameter comprises the deformation direction and the deformation quantity.
In the embodiment of the present invention, the display screen of the terminal may deform, and at this time, in order to improve the user experience of the terminal, in the process of deforming the display screen of the terminal, the currently displayed picture may be adjusted, for example, enlarged or reduced, so as to present different visual effects.
That is, when a deformation operation for the display screen of the terminal is detected, the currently displayed screen is adjusted through the following steps 202 to 204 according to the deformation parameter corresponding to the deformation operation.
Specifically, the terminal may determine the deformation parameter corresponding to the deformation operation through a sensor installed in the terminal, that is, when the deformation operation for the display screen of the terminal is detected, the sensor in the terminal detects the deformation parameter corresponding to the deformation operation in real time.
The sensor is any sensor capable of testing deformation parameters, such as a pressure sensor, an acceleration sensor or an angle sensor.
The deformation operation is any operation for deforming the display screen of the terminal, and the deformation operation may be a pressing operation, a bending operation, or a twisting operation, and the like.
In addition, the deformation parameter is used for describing the deformation degree of the display screen of the terminal under the deformation operation, and the deformation parameter comprises the deformation direction and the deformation quantity. Specifically, when the deformation operation is a pressing operation, the deformation parameters are a pressing direction and a pressing pressure corresponding to the pressing operation. When the deformation operation is a twisting operation, the deformation parameter is a twisting direction, a twisting angle and/or a twisting stress corresponding to the twisting operation. When the deformation operation is a bending operation, the deformation parameter is a bending direction, a bending angle and/or a bending stress corresponding to the bending operation.
For example, when the deformation operation is a pressing operation, the terminal may detect, in real time, a pressing pressure and a pressing direction corresponding to the pressing operation through a pressure sensor disposed in the terminal. When the deformation operation is a bending operation, the terminal may detect a bending direction and a bending angle corresponding to the bending operation in real time through an angle sensor disposed in the terminal.
In particular, for a bendable terminal based on a flexible display screen, the deformation operation may specifically be a bending operation, the deformation direction included in the deformation parameter may specifically be a bending direction, and the deformation amount included in the deformation parameter may specifically be a bending angle.
Fig. 2B is a schematic diagram of a bendable terminal based on a flexible display screen according to an embodiment of the present invention, as shown in fig. 2B, before bending, a display area of the display screen of the terminal is a flat area, and after bending, the display area of the display screen of the terminal is a curved area.
The radian of the sector area corresponding to the curved surface area in the direction vertical to the plane of the display screen can represent the bending degree of the display screen. And the larger the radian is, the smaller the bending degree of the display screen is, namely, the smaller the bending angle is. The smaller the radian is, the more the display screen is bent, i.e. the larger the bending angle is.
As shown in fig. 2B, the deformation direction of the terminal may have two different directions, one is the direction from the display to the back of the terminal, i.e. the direction away from the display, and the other is the direction from the back of the terminal to the display, i.e. the direction towards the display. For convenience of description, a direction away from the display screen is referred to as a first preset direction, and a direction toward the display screen is referred to as a second preset direction.
The area on the back side of the terminal is referred to as the outside of the display, and the area on the display side of the terminal is referred to as the inside of the display.
As shown in fig. 2C, when the center of the sphere of the spherical surface where the curved surface region is located is outside the display screen, the deformation direction of the display screen is the first predetermined direction.
As shown in fig. 2D, when the center of the sphere of the spherical surface where the curved surface region is located inside the display screen, the deformation direction of the display screen is also the second predetermined direction.
Step 202: and acquiring the view field width corresponding to the deformation parameter according to the deformation direction and the deformation quantity, wherein the view field width is used for describing the view field range of the user.
That is, in the embodiment of the present invention, different deformation parameters correspond to different view widths, so as to adjust the view range of the user. Because the deformation amount in the deformation parameter is used for describing the deformation degree of the display screen, the view field width can be adjusted according to the deformation amount, namely the view field width corresponding to the deformation amount is obtained.
Specifically, in order to realize different visual effects according to deformation of the display screen, different view field widths are set for different deformation amounts, and the view field width is larger when the deformation amount is larger, or the view field width is smaller when the deformation amount is larger.
In particular, for the terminal shown in fig. 2B, as shown in step 201, the deformation direction of the display screen may be a first preset direction or a second preset direction, and in this case, there are two possible implementations of step 202.
In a first possible implementation manner, when the deformation direction is a first preset direction, a reduction scale corresponding to the deformation amount is determined, and the original view width is reduced according to the reduction scale, so as to obtain a view width corresponding to the deformation parameter.
As shown in fig. 2C, when the deformation direction is the first preset direction, that is, the deformation direction is a direction away from the display screen, it indicates that the display screen is deformed outward at this time, and at this time, in order to improve user experience, the currently displayed picture may be enlarged, so that the user feels an effect that the current picture is drawn, that is, the view field width of the user is reduced.
Wherein, determining the reduction ratio corresponding to the deformation amount may specifically be: when the deformation quantity does not exceed a first preset deformation quantity, determining a reduction ratio which is positively correlated with the deformation quantity; when the deformation amount exceeds the first preset deformation amount, setting the reduction ratio corresponding to the deformation amount as a first preset ratio.
That is, when the amount of deformation of the display screen is within a certain range, the reduction ratio is larger as the amount of deformation of the display screen is larger. When the deformation of the display screen exceeds the certain range, the reduction ratio is a fixed value and does not change any more.
For example, as shown in fig. 2C, the deformation is a bending angle, the preset deformation is 30 °, and when the bending angle is smaller than 30 °, the reduction ratio is increased with the increase of the bending angle, so as to present the effect that the current picture is gradually pulled closer. When the bending angle is greater than 30 °, the reduction ratio is not changed, that is, the current picture is not changed.
Wherein the implementation of determining the reduction scale positively correlated to the deformation amount may be; multiplying the deformation quantity by a correlation factor to obtain the reduction ratio, wherein the correlation factor is a positive value so as to satisfy that the reduction ratio and the deformation quantity are in positive correlation.
In addition, the original view width is a preset view width. For example, the original view width may be a view width of a picture displayed when the deformation amount of the display screen is 0, and the view width may also be a view width of a picture displayed before the deformation of the display screen occurs at this time.
In a second possible implementation manner, when the deformation direction is a second preset direction, an amplification scale corresponding to the deformation amount is determined, and the original view width is amplified according to the amplification scale, so that the view width corresponding to the deformation parameter is obtained.
As shown in fig. 2D, when the deformation direction is the second preset direction, that is, the deformation direction is toward the display screen, it indicates that the display screen is deformed inward, and at this time, in order to improve the user experience, the currently displayed picture may be reduced, so that the user feels the effect that the current picture is pulled away, that is, the view field width of the user is increased.
Wherein, the determining of the amplification ratio corresponding to the deformation amount may specifically be: when the deformation quantity does not exceed a second preset deformation quantity, determining an amplification ratio positively correlated with the deformation quantity, and when the deformation quantity exceeds the second preset deformation quantity, setting the amplification ratio corresponding to the deformation quantity as a second preset ratio.
That is, when the deformation amount of the display screen is within a certain range, the magnification ratio is larger as the deformation amount of the display screen is larger, so as to present an effect that the current screen is gradually zoomed out. When the deformation of the display screen exceeds the certain range, the amplification ratio is a fixed value and does not change any more, namely the current picture does not change any more.
Step 203: and adjusting the currently displayed picture according to the view width.
Specifically, a central point of a deformation area of the display screen is determined, a pixel point of a currently displayed picture at the central point is obtained, a central pixel point is obtained, and a picture corresponding to the view width is determined by taking the central pixel point as a center in an original picture of the currently displayed picture, so that the currently displayed picture is adjusted.
The original picture of the current display picture can be an original acquisition picture of the current display picture. For example, the current display frame is a video frame of the panoramic video in a certain view width, and at this time, the original frame of the current display frame is also a video frame of the panoramic video in the whole view width.
Particularly, when the display screen is the display screen shown in fig. 2B, the central point of the deformation region of the display screen is also the central point of the curved surface region, and at this time, the picture corresponding to the view width is determined according to the central pixel point, so that the picture displayed near the central point of the curved surface region can be zoomed in or zoomed out.
For example, as shown in fig. 2C, for two possible implementation manners in step 202, when the deformation direction is the first preset direction, since the view width is obtained by reducing the original view width, determining the picture corresponding to the view width is equivalent to enlarging the current display picture to achieve the effect of zooming in the current display picture.
As shown in fig. 2D, when the deformation direction is the second preset direction, since the view width is obtained by enlarging the original view width, determining the picture corresponding to the view width is equivalent to reducing the current display picture, so as to achieve the effect of zooming out the current display picture.
As can be seen from the above process, in the embodiment of the present invention, according to the position where the deformation occurs in the display screen, the current display screen may be adjusted to be zoomed in or zoomed out at the position where the deformation occurs.
Optionally, in the embodiment of the present invention, after the view width is determined, when a preset operation for the display screen is detected, a position where the preset operation acts on the display screen is determined, and then a picture corresponding to the view width is determined with a pixel point at the position as a central pixel point.
That is, after determining the view width, the terminal may perform zoom-in or zoom-out adjustment on the picture at the position according to the position where the user acts on the display screen through the preset operation.
Step 204: and displaying the adjusted picture in the display screen.
As shown in fig. 2C, when the deformation direction is the first preset direction, the adjusted image is displayed on the display screen in step 204, so that the current display image can be zoomed in.
As shown in fig. 2D, when the deformation direction is the second preset direction, the adjusted picture is displayed on the display screen in step 204, so that the current displayed picture can be zoomed out.
In the embodiment of the invention, when the deformation operation aiming at the display screen of the terminal is detected, the deformation parameter corresponding to the deformation operation is determined, the view field width corresponding to the deformation parameter is obtained, and the currently displayed picture is adjusted according to the view field width. Because the view width is used for describing the view range of the user, the picture display method provided by the embodiment of the invention can adjust the view width of the current display picture according to the deformation of the display screen of the terminal, so as to bring different visual feelings to the user and improve the user experience of the terminal.

The touch display screen 430 is used for receiving a touch operation of a user on or near the touch screen using any suitable object such as a finger, a touch pen, or the like, and displaying a user interface of each application. The touch display 430 is generally disposed on a front panel of the terminal 430. The touch display screen 430 may be designed as a full-face screen, a curved screen, or a profiled screen. The touch display 430 can also be designed as a combination of a full-screen and a curved-surface screen, and a combination of a special-shaped screen and a curved-surface screen, which is not limited in this embodiment. Wherein:
full screen
A full screen may refer to a screen design where the touch display 430 occupies more than a threshold (e.g., 80% or 90% or 95%) of the screen of the front panel of the terminal 400. One way of calculating the screen occupation ratio is as follows: (area of touch display 430/area of front panel of terminal 300) × 100%; another way to calculate the screen ratio is: (area of actual display area in touch display 430/area of front panel of terminal 400) × 100%; another calculation method of the screen occupation ratio is as follows: (diagonal of touch display 430/diagonal on front panel of terminal 400) × 100%. In the illustrative example shown in fig. 6A, almost all areas on the front panel of the terminal 400 are the touch display 430, and all areas on the front panel 50 of the terminal 400 except for the edge created by the center frame 51 are the touch display 430. The four corners of the touch display screen 430 may be right angles or rounded.
A full-screen may also be a screen design that integrates at least one front panel component within or underneath the touch display screen 430. Optionally, the at least one front panel component comprises: cameras, fingerprint sensors, proximity light sensors, distance sensors, etc. In some embodiments, other components on the front panel of the conventional terminal are integrated in all or a part of the touch display screen 430, for example, after the light sensing element in the camera is split into a plurality of light sensing pixels, each light sensing pixel is integrated in a black area in each display pixel in the touch display screen 430. The full-screen has a higher screen-to-screen ratio due to the integration of at least one front panel component inside the touch display screen 430.
Of course, in other embodiments, the front panel component of the front panel of the conventional terminal may be disposed on the side or back of the terminal 400, such as disposing the ultrasonic fingerprint sensor below the touch screen 430, disposing the bone conduction earpiece inside the terminal 430, and disposing the camera in a pluggable structure on the side of the terminal.
In some optional embodiments, when the terminal 400 employs a full-screen, a single side, or two sides (e.g., two left and right sides), or four sides (e.g., four upper, lower, left and right sides) of the middle frame of the terminal 400 is provided with an edge touch sensor, and the edge touch sensor is configured to detect at least one of a touch operation, a click operation, a press operation, a slide operation, and the like of a user on the middle frame. The edge touch sensor may be any one of a touch sensor, a thermal sensor, a pressure sensor, and the like. The user may apply operations on the edge touch sensor to control applications in the terminal 400.
Curved surface screen
A curved screen refers to a screen design where the screen area of the touch display screen 430 does not lie in one plane. Generally, curved screens present at least one such section: the section is in a curved shape, and the projection of the curved screen in any plane direction perpendicular to the section is a planar screen design, wherein the curved shape can be U-shaped. Alternatively, a curved screen refers to a screen design where at least one side is curved. Alternatively, the curved screen means that at least one side edge of the touch display screen 430 extends to cover the middle frame of the terminal 400. Since the side of the touch display screen 430 extends to cover the middle frame of the terminal 400, that is, the middle frame which does not have the display function and the touch function originally is covered as the displayable area and/or the operable area, the curved screen has a higher screen occupation ratio. Alternatively, as in the example shown in fig. 6B, the curved screen refers to a screen design in which the left and right side edges 52 are curved; or, the curved screen refers to a screen design in which the upper and lower sides are curved; or, the curved screen refers to a screen design in which the upper side, the lower side, the left side and the right side are all in a curved shape. In an alternative embodiment, the curved screen is made of a touch screen material with certain flexibility.
Special-shaped screen
The special-shaped screen is a touch display screen with an irregular shape, and the irregular shape is not a rectangle or a rounded rectangle. Optionally, the irregular screen refers to a screen design in which a protrusion, a notch, and/or a cutout is provided on the rectangular or rounded rectangular touch display screen 430. Alternatively, the protrusions, indentations, and/or cutouts may be located at the edges of the touch screen 430, at the center of the screen, or both. When the protrusion, the notch and/or the dug hole are arranged on one edge, the protrusion, the notch and/or the dug hole can be arranged in the middle or at two ends of the edge; when the projection, notch and/or cutout is provided in the center of the screen, it may be provided in one or more of an upper region, an upper left region, a left side region, a lower left region, a lower right region, a right side region, and an upper right region of the screen. When the projections, the notches and the dug holes are arranged in a plurality of areas, the projections, the notches and the dug holes can be distributed in a concentrated mode or in a dispersed mode; the distribution may be symmetrical or asymmetrical. Optionally, the number of projections, indentations and/or cutouts is also not limited.
The special-shaped screen covers the upper forehead area and/or the lower forehead area of the touch display screen as the displayable area and/or the operable area, so that the touch display screen occupies more space on the front panel of the terminal, and the special-shaped screen also has a larger screen occupation ratio. In some embodiments, the indentation and/or cutout is configured to receive at least one front panel component therein, the front panel component including at least one of a camera, a fingerprint sensor, a proximity light sensor, a distance sensor, an earpiece, an ambient light level sensor, and a physical key.
For example, the notch may be provided on one or more edges, and the notch may be a semicircular notch, a right-angled rectangular notch, a rounded rectangular notch, or an irregularly shaped notch. In the exemplary embodiment shown in fig. 6C, the special-shaped screen may be a screen design with a semicircular notch 53 at the center of the upper edge of the touch display screen 430, where the semicircular notch 53 is used to accommodate at least one of a front panel component of a camera, a distance sensor (also called a proximity sensor), an earpiece, and an ambient light sensor; as schematically shown in fig. 6D, the irregular-shaped screen may be a screen design in which a semicircular notch 54 is formed at the center of the lower edge of the touch display screen 430, and the semicircular notch 54 is free for accommodating at least one of a physical key, a fingerprint sensor, and a microphone; in an exemplary example shown in fig. 6E, the special-shaped screen may be a screen design in which a semi-elliptical notch 55 is formed in the center of the lower edge of the touch display screen 430, and a semi-elliptical notch is also formed on the front panel of the terminal 400, and the two semi-elliptical notches form an elliptical area for accommodating a physical key or a fingerprint identification module; in the illustrative example shown in fig. 6F, the shaped screen may be a screen design having at least one aperture 55 disposed in the upper half of the touch screen 430, the aperture 55 being free to receive at least one of a camera, a distance sensor, an earpiece, and an ambient light level sensor.
