In embodiments of the present application, a folded display may be included in the electronic device 100, and in some embodiments, an additional display may be included on the back of the folded display.
The acceleration sensor 180E may detect the magnitude of acceleration of the electronic device 100 in various directions (typically three axes). The magnitude and direction of gravity may be detected when the electronic device 100 is stationary. The electronic equipment gesture recognition method can also be used for recognizing the gesture of the electronic equipment, and is applied to horizontal and vertical screen switching, pedometers and other applications.
The gyro sensor 180B may be used to determine a motion gesture of the electronic device 100. In some embodiments, the angular velocity of electronic device 100 about three axes (i.e., x, y, and z axes) may be determined by gyro sensor 180B.
As shown in fig. 2a and 2b, the electronic device 100 has, for example, a first display 1941 and a second display 1942, where the first display 1941 is a folded display and the second display 1942 is located at a back side of the first display 1941. The electronic device 100 may include a plate-shaped first folded portion 11 and a plate-shaped second folded portion 12, the first folded portion 11 and the second folded portion 12 are located on the same plane in a fully unfolded state of the electronic device 100, a portion of the first display 1941 is located on one side surface of the first folded portion 11, another portion of the first display 1941 is located on one side surface of the second folded portion 12, the second display 1942 is located on the other side surface of the first folded portion 11, and the first folded portion 11 is located between the first display 1941 and the second display 1942; in the fully folded state of the electronic device, the first folded portion 11 and the second folded portion 12 are attached to each other, and the folded first display 1941 is located between the first folded portion 11 and the second folded portion 12. The electronic device 100 has a fully folded state and a fully unfolded state, as shown in fig. 3a, in the fully unfolded state, a folding included angle a of the first display screen 1941 is 180 °, when the electronic device 100 is unfolded, the first display screen 1941 can display a picture, so that a user can conveniently watch a larger-sized display screen picture and perform touch operation, and the second display screen 1942 is at rest; as shown in fig. 3b, in the fully folded state, the first display screen 1941 is folded and the light emitting surfaces of the first display screen 1941 are attached to each other, at this time, the folding included angle a of the first display screen 1941 is 0 °, when the electronic device 100 is folded, the first display screen 1941 is buckled, and the second display screen 1942 can display a picture, so that a user can watch the display picture and perform touch operation in the folded state of the electronic device 100, and the first display screen 1941 is in the screen; as shown in fig. 3c, when the electronic device 100 is in the semi-folded state, the electronic device 100 switches the display states according to the folding angle a, for example, in the related art, if a is greater than or equal to 80 °, the first display 1941 is controlled to display a screen, the second display 1942 is controlled to display a screen, if a is less than 80 °, the first display 1941 is controlled to display a screen, and the second display 1942 is controlled to display a screen, however, in this manner of switching the display states by fixing the threshold value, if the electronic device 100 hovers at 80 °, or the user expands or buckles the electronic device 100 at a slower speed, the flicker of the two display screens may be caused. The electronic device 100 may have errors or jitter when calculating the folding angle a through the sensor, that is, for example, even if the current folding angle a of the electronic device 100 is determined to be 79.8 °, the theoretical display state should be determined, but the folding angle sensed and calculated by the electronic device 100 through the sensor may be continuously changed around 80 ° due to the errors, so that the flickering problem of the display screen may be caused.
In other possible embodiments, the electronic device 100 may have only one display of the first display 1941. The electronic device 100 having only the first display 1941 also performs display state switching according to the folding angle a, for example, when the folding angle of the first display 1941 is smaller, the first display 1941 is controlled to display a screen, so as to reduce power consumption, and when the folding angle of the first display 1941 is larger, the first display 1941 is controlled to display a screen, so as to be convenient for a user to watch. There is also a flicker of the display screen that may be caused when switching the display state based on a fixed threshold.
Therefore, the embodiment of the application provides an improved scheme which can improve the problem of screen flickering.
Before starting the description of the embodiments of the present application, it is necessary to introduce a description of related technical principles to facilitate understanding of the improved solutions proposed by the embodiments of the present application.
The principle of one method of acquiring the folding angle a of the first display screen 1941 based on the gyro sensor 180B is described below.
Assume that one point coordinate in the two-dimensional space is (x m ，y m ) The point is rotated counterclockwise by an angle delta, and the coordinates of the rotated point are (x n ，y n ) The conversion formula is provided between the two:
As shown in fig. 4, it is assumed that there is a coordinate system X in a two-dimensional space M OY M The coordinate system rotates counterclockwise around the O point by an angle delta to become a coordinate system X N OY N Assuming a P point, in the coordinate system X M OY M The coordinates of the P point in the middle are (x m ，y m ) In the coordinate system X N OY N The coordinates of the P point in the middle are (x n ，y n ) The geometric relationship according to the two-dimensional space can be obtained:
wherein, the liquid crystal display device comprises a liquid crystal display device,
is a coordinate system X M OY M OP vector in>
Is a coordinate system X N OY N OP vector in (a) is provided. It can be seen that the coordinate system rotates counter-clockwise by an angle delta, equivalent to the point rotation angle delta.
The first folded portion 11 is provided with a corresponding acceleration sensor and gyroscope, and the second folded portionThe folding portion 12 is provided with a corresponding acceleration sensor and a gyroscope, and the acceleration sensor can detect acceleration component values on three axes, for example, when the folding portion is stationary, no acceleration motion exists, but due to the action of gravity acceleration, the acceleration sensed by the folding portion is opposite to the gravity acceleration, namely, the read data are numerical upward, namely, when the acceleration sensor is placed horizontally and vertically along the Z axis, the read acceleration values of the two directions of the X axis and the Y axis are 0, the read acceleration value of the Z axis is 9.8, namely, the read data are (0, 9.8). During folding or unfolding of the electronic device 100, one axis is unchanged, and only two axes are changed, that is, during the change of the folding angle of the first display screen 1941, the acceleration values of the two axes in the acceleration sensor are changed. The change of the folding angle of the first display 1941 can be analogous to the rotation process of the coordinate system or the rotation process of the point in the two-dimensional space, for example, before the change of the folding angle of the first display 1941, the acceleration values of the two axes in the acceleration sensor at the first folding portion 11 are respectively taken as (x) m ，y m ) After the folding angle of the first display 1941 is changed, the acceleration values of the two axes in the acceleration sensor at the first folding portion 11 are respectively taken as (x n ，y n ) The rotation angle delta of the first folding portion 11 can be obtained by solving the first formula, and the rotation angle of the second folding portion 12 can be obtained by a similar principle, namely, the folding included angle between the first folding portion 11 and the second folding portion 12, namely, the folding included angle of the first display screen 1941 can be obtained.
As shown in fig. 5, an embodiment of the present application provides a state switching method for an electronic device 100, where the electronic device 100 includes a first display 1941, the first display 1941 is a folded display, and the state switching method includes:
the folding angle a is an angle between two parts of the electronic device that are in a fully unfolded state and a fully folded state, that is, the first display 1941 can be folded relatively, and the change trend of a includes that a is changed from large to small or a is changed from small to large, that is, a is changed from large to small, that is, the first display 1941 is being buckled, and a is changed from small to large, that is, the first display 1941 is being unfolded.
that is, according to the variation trend of a, different display state switching thresholds γ are set, a larger γ value is set when a is changed from small to large, a smaller γ value is set when a is changed from large to small, and hereinafter, described by way of a specific example, assuming a1=77°, a2=82°, as shown in fig. 6a, γ is set to a larger angle 82 ° when a variation trend of a is changed from small to large, that is, when the electronic device 100 is unfolded, as shown in fig. 6b, γ is set to a smaller angle 77 ° when a variation trend of a is changed from large to small, that is, when the electronic device 100 is fastened.
Specifically, taking a1=77°, a2=82° as an example, when the change trend of a is from large to small, that is, when the electronic device 100 is buckled, when a is greater than or equal to 77 °, the first display 1941 is in the first display state, and when a is less than 77 °, the first display 1941 is in the second display state, that is, the display state is switched based on the threshold of 77 °; when the change trend of a is from small to large, that is, when the electronic device 100 is unfolded, when a is greater than or equal to 82 degrees, the first display 1941 is in the first display state, and when a is less than 82 degrees, the first display 1941 is in the second display state, that is, the display state is switched based on the threshold value of 82 degrees. The determining manner of the folding angle a of the first display screen 1941 may be obtained by calculating the data read by the acceleration sensor, and the above is merely an illustration of obtaining the folding angle of the first display screen 1941, and the obtaining manner of the folding angle of the first display screen 1941 in the embodiment of the present application is not limited.
According to the state switching method, the display state switching threshold value of the smaller angle is set when the first display screen is buckled, the display state switching threshold value of the larger angle is set when the first display screen is unfolded, and certain buffering is needed when one display state is switched to the other display state through the hysteresis display state switching threshold value setting mode, even if the first display screen is unfolded or buckled at a lower speed, flicker is not easy to be caused due to frequent switching between different display states even if the calculated folding included angle has errors, and frequent switching between different display states is not generated when the first display screen hovers at a certain included angle.
In one possible implementation, as shown in fig. 7, the state switching method further includes:
Specifically, when the angular velocity ω is greater, it indicates that the user is controlling the electronic device 100 to expand or buckle at a faster speed, and indicates that the user's willingness to switch the display state is relatively obvious, so that in the process of changing the trend of a from a smaller trend, that is, in the process of controlling the electronic device 100 to buckle, the display state switching threshold γ is set to be greater, so that the electronic device 100 performs display state switching faster, and in the process of changing the trend of a from a smaller trend, that is, in the process of controlling the electronic device 100 to expand, the display state switching threshold γ is set to be smaller, so that the electronic device 100 performs display state switching interchangeably. It should be noted that, in the process illustrated in fig. 7, step 108 is located before step 101, the execution sequence between step 108 and step 101 is not limited, and the angular velocity ω may be obtained first, then the change trend of a and a may be obtained, the change trend of a and a may be obtained first, then the angular velocity ω may be obtained, or the change trend of a and a may be obtained simultaneously.
In one possible embodiment, as shown in fig. 8a and 8b, a > A1 > θ,
alpha, theta and>
