Detailed Description
The technical solution in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
Referring to fig. 1, fig. 1 is a schematic flow chart of a method for preventing a foldable screen device from being touched by mistake according to an embodiment of the present application, where the method for preventing a foldable screen device from being touched by mistake includes the following specific steps:
step S11: and determining that the first display unit and the second display unit are in a rotating state based on the gravity sensing data of the first display unit and the second display unit in the bright screen state.
The first display unit and the second display unit may be two independent display screens capable of rotating around a rotation axis in the foldable screen device.
Specifically, the step S11 may specifically include the following sub-steps:
step S111: and determining a first gravity sensing data change value of the first display unit in a bright screen state and a second gravity sensing data change value of the second display unit in a bright screen state.
The first gravity-sensing data variation value may be represented as Δ a1, and the second gravity-sensing data variation value may be represented as Δ a 2.
Optionally, in this embodiment, the first gravity sensing data and the second gravity sensing data change value may be collected by a gravity sensing sensor, the gravity sensing sensor may be a cantilever type shifter made of an elastic sensing element, and an energy storage spring made of the elastic sensing element drives an electrical contact to convert the gravity change into an electrical signal and send the electrical signal to an operation unit of the foldable screen device for analysis. The working principle is piezoelectric effect, namely when the dielectric medium is deformed under the action of external force in a certain direction, the polarization phenomenon can occur inside the dielectric medium, so that voltage is generated on two opposite surfaces, and the foldable screen device is suitable for foldable screen equipment with the angle rotation between screens.
Therefore, when the acceleration state of the gravity sensing sensor in the foldable screen device changes, the information can be represented in a voltage form. The corresponding piezoelectric gravity sensing sensor is arranged in the foldable screen device, and various state accelerations of the user in daily use are deeply learned based on a corresponding algorithm, so that the actual state of the foldable screen device can be determined.
The actual state of the foldable screen device is determined in a deep learning mode, which is similar to the existing common deep learning mode and is not described herein again.
Step S112: and when the change value of the first gravity sensing data or the change value of the second gravity sensing data is greater than the preset gravity reference value, determining that the first display unit and the second display unit are in a rotating state.
The preset gravity change reference value can be expressed as M, and the value of M can be flexibly adjusted according to the specific size, weight and the like of the foldable screen device.
Specifically, M is set according to the maximum change value of the gravitational acceleration that can be accepted by a user who normally uses the foldable screen device in daily life, and if the absolute value of the change exceeds M, it represents that the foldable screen device is being folded, unfolded or in motion, and these scenes are obviously not suitable for the user to normally use, and the probability of the occurrence of the false touch is very high, so that the false touch prevention needs to be performed on the foldable screen device.
Step S12: and suppressing the touch response of the folding identification areas in the first display unit and the second display unit through a touch panel driving program.
Optionally, the suppression of the touch response in this embodiment may be to eliminate or screen the driving signal applied to the folding recognition area by the driving line selection. The driving line is used for transmitting the driving signal of the processing unit or the arithmetic unit to the screen so as to drive the screen to display.
Specifically, the specific manner of suppressing the touch response of the folding identification area may include:
the first method is as follows: and carrying out grounding processing on the driving wires in the range of the folding identification area by a touch panel driving program.
The second method comprises the following steps: and disconnecting the electric signal circuit fed back from the folding identification area for a preset time by a touch panel driving program.
The preset disconnection duration of the electric signal line can be flexibly set according to the characteristic of preventing false touch.
In addition to the mistouch prevention determination according to the unfolding and folding operation states or motion states of the first display unit and the second display unit, the mistouch prevention determination can be performed according to whether the foldable screen device is in a state that a user can guarantee stable holding of the device without touching the touch area.
Referring to fig. 2 and fig. 3, fig. 2 is a schematic view illustrating an included angle between a display unit of an unfolding plane and a horizontal plane according to an embodiment of the present application, and fig. 3 is a schematic view illustrating a flow of performing a false touch prevention determination based on an included angle between the unfolding plane of a foldable screen device and the horizontal plane according to an embodiment of the present application.
Fig. 2 is a schematic diagram showing an included angle between a display unit and a horizontal plane of a foldable screen device gravity sensing sensor for monitoring an unfolding plane, as shown in the figure, when the included angle between the display unit and the horizontal plane is smaller than or equal to a certain angle, a mobile phone screen displays downwards, a possible user use state is that a user operates a mobile phone in a lying state, at the moment, the screen is in the unfolding state, the width of the mobile phone is large, the mobile phone is not convenient to hold by one hand, the operation in a lifting mobile phone posture is not possible, when the user holds the mobile phone by two hands for use, the error touch of the edge of the screen is very easy to occur, and therefore, the necessity of preventing.
Specifically, the procedure of performing the false touch prevention determination based on the plane included angle between the unfolding plane of the foldable screen device and the horizontal plane may be as follows:
step S131: and when the change value of the first gravity sensing data or the change value of the second gravity sensing data is smaller than or equal to the preset gravity change reference value, determining a screen included angle between the first display unit and the second display unit.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a screen angle according to an embodiment of the present application.
When the change value of the first gravity sensing data or the change value of the second gravity sensing data is smaller than or equal to the preset reference value of gravity change, it indicates that the foldable screen device is not folded, unfolded or moved currently, and this condition is a precondition that the user is using the foldable screen device normally.
Alternatively, the screen angle in this embodiment may be denoted as b, and an angle detection sensor may be used to detect the screen angle between two display units.
Step S132: and when the screen included angle accords with the preset included angle range, determining that the foldable screen equipment is in the unfolding state.
It should be understood that, since the foldable screen device has two modes of inward turning and outward turning, and the specific reference value calculation mode is different, this embodiment is only a broad expression, and the specific parameter setting and algorithm design should be set according to the suitable angle of the state that both display units of the foldable screen can normally display and operate in practical use of the user, so that the range conforming to the preset included angle in this embodiment may be greater than or equal to a preset included angle reference value or less than or equal to a preset included angle reference value according to the inward turning or outward turning mode of the foldable screen device.
Alternatively, the preset included angle reference value in this embodiment may be represented as N.
Step S133: and determining a plane included angle between an unfolding plane of the foldable screen device and a horizontal plane based on the gravity sensing data of the first display unit and the second display unit.
Determining the included angle between the device and the horizontal plane through gravity sensing data belongs to a common calculation method in the field, and is not described herein again.
Step S134: and when the plane included angle is smaller than or equal to the preset plane included angle reference value, inhibiting the touch response of the folding identification area through a touch panel driving program.
Alternatively, the plane angle in this embodiment may be represented as c, and the preset plane angle reference value may be represented as P.
The selected value of P is set according to the change condition of the holding mode of the foldable screen device under the normal use state of a user.
