When the flexible display screen 102 is unfolded, one of the width and the length of the flexible display screen 102 changes in size along with the unfolding of the flexible display screen 102, the other changes, the size value of the size-changed person is measured by the detector 103, the unfolding size of the flexible display screen 102, namely the unfolding length of the flexible display screen 102, can be obtained, and the unfolding area of the flexible display screen 102 is the product value of the unfolding length and the width.
The extending direction of the flexible display screen 102 may be a stretching direction along the length or width direction of the flexible display screen 102, as shown in fig. 2A.
Or may be spread 180 degrees back along the length or width of the flexible display screen 102, as shown in fig. 2B.
In this embodiment, the unfolding size is the unfolding length of the flexible display screen 102, and the example is described in which the width of the flexible display screen 102 is not changed, and the length is increased along with the unidirectional unfolding of the flexible display screen 102, that is, the flexible display screen 102 is unfolded along the length direction of the flexible display screen 102.
Illustratively, the width of the flexible display screen 102 is W, wherein the width W keeps the same size during the expansion of the flexible display screen 102, the length L becomes larger as the flexible display screen 102 expands, i.e., L is a variable, and the maximum value of the expanded length is Lmax, wherein Lmax ≧ L ≧ 0.
A plurality of tags 100 are arranged in the unfolding direction of the flexible display screen 102, and the tags 100 store corresponding size information of the flexible display screen 102, which may be a length value or an area value of the flexible display screen 102 in the current unfolding direction.
When the flexible display screen 102 is unfolded, the detector 103 reads the information of the corresponding tag 100, so as to obtain the current unfolded size of the flexible display screen 102, that is, the current unfolded length L.
In some possible embodiments, the flexible display screen 102 is rolled up in the housing 101 by a reel, and the rolled-up size of the flexible display screen 102 can be obtained by detecting the number of turns of the reel.
Step S102: and controlling the flexible display screen to display virtual keyboards in different forms according to the expansion size, wherein the virtual keyboards in different forms are virtual keyboards with different sizes or different placing directions.
Referring to FIG. 3, in some possible embodiments, step S102 includes steps S201-S205.
In step S201, the expansion size of the flexible display screen is obtained.
Step S202, determining whether the expansion size is greater than a first threshold and less than or equal to a second threshold, and if the expansion size is greater than the first threshold and less than or equal to the second threshold, executing step S203, otherwise executing step S204.
Specifically, the first threshold and the second threshold may be preset, or may be set by a user as needed, where the second threshold is greater than the first threshold. The electronic device 10 acquires the current unfolding size of the flexible display screen 102 through the detector 103, and determines whether the acquired current unfolding size is larger than a first threshold and smaller than a second threshold.
For example, the first threshold is A and the second threshold is B, where B > A. The detector 103 detects that the current expansion size of the flexible display screen 102 is L1, determines whether B > L1 > a holds, and executes step S203 when B > L1 > a holds, otherwise executes step S204.
Step S203, when the unfolding size is detected to be larger than the first threshold value and smaller than the second threshold value, the virtual keyboard is controlled to be placed on the flexible display screen along the first direction.
As shown in fig. 4, when the electronic device 10 detects that the extended length of the flexible display screen 102 is L1 and B > L1 > a, the virtual keyboard 104 is controlled to be placed on the flexible display screen 102 along the first direction, and when the virtual keyboard 104 is placed on the flexible display screen 102 along the first direction, the size of the virtual keyboard 104 is the first size, and the size of the virtual keyboard 104 may be the length, the width, or the area of the virtual keyboard 104.
Preferably, when the expanded size of the flexible display screen 102 is greater than the first threshold and less than the second threshold, the virtual keyboard 104 is placed in the first direction, and the display area of the virtual keyboard 104 remains unchanged.
Preferably, the first threshold a is W/2, and the second threshold B is W, which is the width of the flexible display screen 102.
And S204, judging whether the unfolding size is larger than or equal to a second threshold value, executing the step S205 when the unfolding size of the flexible display screen is larger than or equal to the second threshold value, and otherwise, continuing to execute the step S204.
And S205, when the unfolding size is larger than or equal to the second threshold value, controlling the virtual keyboard to be placed on the flexible display screen along the second direction.
Preferably, when the expanded size is greater than the first threshold and less than or equal to a second threshold, the virtual keyboard 104 is displayed in a preset size. The preset size is a display size of the virtual keyboard 104, that is, a length and a width, or an area of the virtual keyboard 104.
As shown in FIG. 5, when the electronic device 10 detects that the extended length of the flexible display screen 102 is L2 and L2 ≧ B, the virtual keyboard 104 is controlled to be placed on the flexible display screen 102 along the second orientation, and when the virtual keyboard 104 is placed on the flexible display screen 102 along the second orientation, the size of the virtual keyboard 104 is the second size, and the second size is larger than the first size. Wherein the first orientation and the second orientation are arranged at an angle, preferably 90 °, i.e. the first orientation and the second orientation are perpendicular to each other.
When the flexible display screen 102 is unfolded, the size of the flexible display screen 102 only changes along the unfolding direction, that is, the unfolding area of the flexible display screen 102 changes from small to large in the unfolding process of the flexible display screen 102, when it is detected that the unfolding size of the flexible display screen 102 along the unfolding direction is larger than a first threshold value and smaller than a second threshold value, the virtual keyboard 104 is controlled to be placed on the flexible display screen 102 along the first direction, and at this time, the size of the virtual keyboard 104 displayed by the flexible display screen 102 is smaller, so that a user can use the virtual keyboard in a smaller space conveniently.
When the flexible display screen 102 continues to be stretched along the unfolding direction, the area of the flexible display screen 102 is increased, and when the unfolding size of the flexible display screen 102 exceeds a set turning threshold value and is greater than or equal to a second threshold value, the virtual keyboard 104 is controlled to be placed on the flexible display screen 102 along a second direction, so that the placing direction selection of the virtual keyboard 104 is increased, and the user experience is improved.
Referring to fig. 6, in some embodiments, step S206 is further included after step S205.
Step S206, when the expansion size is larger than or equal to the second threshold, controlling the virtual keyboard to enlarge or reduce according to the expansion size and a scaling corresponding to the expansion size, wherein the scaling is related to the change of the expansion size.
The expansion size of the flexible display screen 102 is an expansion length of the flexible display screen 102 exposed to the housing 101, wherein the expansion length gradually increases during the expansion process of the flexible display screen 102 and gradually decreases during the curling process of the flexible display screen 102, and the virtual keyboard 40 is enlarged or reduced at a corresponding scaling ratio along with the change of the expansion size of the flexible display screen 102.
In some embodiments, when the expanded size is greater than or equal to the second threshold value, and the expanded size value gradually increases, the virtual keyboard 40 increases at a fixed scale following the increase in the expanded size of the flexible display 102. When the deployed size is greater than or equal to the second threshold value, and the deployed size value gradually decreases, the virtual keyboard 40 decreases at a fixed scale following the decrease in the deployed size of the flexible display 102.
In some embodiments, the scaling up or scaling down of the virtual keyboard 104 according to the expansion size and the scaling k corresponding to the expansion size is specifically: when the expansion size is larger than or equal to the second threshold value and the expansion size value becomes larger gradually, controlling the virtual keyboard 104 to enlarge according to the scaling k; when the expansion size is larger than or equal to the second threshold value and the expansion size value is gradually reduced, the virtual keyboard 104 is controlled to be reduced according to the scaling k, so that the virtual keyboard 104 can be adaptively adjusted along with the expansion size of the flexible display screen 40.
Preferably, when the virtual keyboard 104 is enlarged or reduced according to the expansion size and the scaling ratio k corresponding to the expansion size, a point corresponding to the center of the selected virtual keyboard 104 is used as a reference point, and the selected reference point is used as a scaling center of the virtual keyboard 104; wherein, when the virtual keyboard 104 is zoomed, the position of the reference point is not changed, and the distance between each point on the virtual keyboard 104 and the reference point is increased or decreased according to the zoom ratio k.
Specifically, when the expanded size is greater than or equal to the second threshold, the virtual keyboard 104 size is scaled along with the scaling of the expanded size of the flexible display screen 102, that is, the ratio of the expanded size of the flexible display screen 102 to the virtual keyboard 104 is a constant value α during the expansion of the virtual keyboard 104 along with the flexible display screen 102, that is, the ratio value is constant at α.
In some embodiments, the ratio a of the expanded size of the flexible display 102 to the virtual keyboard 104 may also be variable during expansion.
In this example, a case where the ratio is a constant value α will be described. That is, when the expanded size of the flexible display screen 102 is the second threshold B, the display area of the virtual keyboard 104 is S0，α＝B*W/S 0。S 0Is a predetermined size of the virtual keyboard 104.
Assuming that the current expansion size of the flexible display screen 102 is Li, and the display area of the corresponding virtual keyboard 104 is Si, since the ratio of the expansion size of the flexible display screen 102 to the virtual keyboard 104 is a constant value α, that is, the ratio is
Figure PCTCN2018123491-APPB-000001
Then there is
Figure PCTCN2018123491-APPB-000002
So that the scaling k is given by,
Figure PCTCN2018123491-APPB-000003
where Li is the current unfolded size of the flexible display screen 102 and B is a second threshold, i.e., the scaling k is related to the change of the unfolded size of the flexible display screen 102, i.e., the scaling k becomes larger as the unfolded size of the flexible display screen 102 becomes larger and decreases as the unfolded size of the flexible display screen 102 decreases.
As shown in FIG. 7, when the flexible display 40 has an expanded size L3, L3 ≧ B, the virtual keyboard 104 is enlarged at a zoom scale k.
In the invention, when the virtual keyboard 104 is placed along the second direction, the size of the display area of the virtual keyboard 104 is controlled to change along with the change of the unfolding size of the flexible display screen 102, so that the unfolding area of the flexible display screen 102 is more effectively utilized, and when the display area of the virtual keyboard 104 is increased, the accuracy of the user in knocking the virtual keys can be effectively improved.
