Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. The objects distinguished by "first", "second", and the like are usually a class, and the number of the objects is not limited, and for example, the first object may be one or a plurality of objects. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
Touch screens of electronic devices are mostly capacitive touch screens at present. The capacitive touch screen needs to work by means of electric field signal difference of two thin glass layers, and needs to realize touch by means of a conductor. However, in some scenarios, touch failure may result. For example, when a user is wearing a glove, the touch may fail because the glove is not powered. For another example, when there is water drop on the screen of the electronic device or the screen is in water, the touch screen may fail and touch by mistake. For another example, if the screen of the electronic device is a curved screen, the palm often touches the screen by mistake, which often causes a problem of touching by mistake. Namely, the existing touch screen has the problems of mistaken touch or touch failure and the like in some scenes, and the reliability is low.
Based on this, the application provides a touch area detection method, device, electronic device and medium, which can improve the reliability of touch. The following detailed description is to be read with reference to the specific drawings and examples.
Fig. 1 is a flowchart illustrating a touch area detection method according to an embodiment of the present disclosure. Fig. 2 is a schematic structural diagram of an embodiment of an electronic device 200 provided in the present application. The touch area detection method 100 shown in fig. 1 is applied to the electronic device shown in fig. 2. To describe the touch area detection method 100 in more detail, the electronic device 200 is described in detail with reference to an embodiment.
As shown in fig. 2, the electronic apparatus includes: a target material layer 20, at least one first photoelectric conversion unit 21, and at least one second photoelectric conversion unit 22.
Wherein the first photoelectric conversion unit 21 and the second photoelectric conversion unit 22 are disposed on the outer peripheral side of the target material layer 20. The first photoelectric conversion unit 21 includes M first photoelectric converters 211 arranged in a first direction, and the second photoelectric conversion unit 22 includes N second photoelectric converters 221 arranged in a second direction perpendicular to the first direction.
The layer of target material 20 is used to convert the absorbed first light wave into a second light wave. The first photoelectric converter 211 and the second photoelectric converter 221 are used for converting the received light energy of the second light wave into electric energy. Wherein M and N are positive integers. M is more than or equal to 2, and N is more than or equal to 2.
In some embodiments of the present application, the target material layer 20, the at least one first photoelectric conversion unit 21, and the at least one second photoelectric conversion unit 22 may be disposed between the display panel and the cover plate. That is, the target material layer 20, the at least one first photoelectric conversion unit 21, and the at least one second photoelectric conversion unit 22 may all be disposed over the display panel.
In some embodiments of the present application, the target material layer 20 may be a rectangular parallelepiped, the first direction may be a width direction of the target material layer 20, and the second direction may be a length direction of the target material layer 20. Referring to fig. 2, one first photoelectric conversion unit 21 and one second photoelectric conversion unit 22 are provided on the outer peripheral side of the target material layer 20.
In some embodiments of the present application, referring to fig. 3, 2 first photoelectric conversion units 21 and 2 second photoelectric conversion units 22 may be disposed on an outer circumferential side of the target material layer 20.
In some embodiments of the present application, the layer of target material 20 may absorb the first light wave and convert the first light wave into the second light wave. Also, the layer of target material 20 may guide the second light wave to propagate within the plane of the layer of target material 20 and exit from the sides of the layer of target material 20. That is, the layer of target material 20 may direct the second light wave to an edge of itself.
As one example, the target material layer 20 may redirect light rays incident perpendicular to the target material layer 20 out the sides of the target material layer 20 using a scattering effect or an embedded dye.
For example, the target material layer 20 is a transparent glass with a fluorescent dye or quantum dots embedded or coated on the surface. The dye in the layer of target material 20 absorbs the first light wave and generates a second light wave that propagates by total internal reflection to the edges of the layer of target material 20, exiting the sides of the layer of target material 20.
In some embodiments, the target material layer 20 may be a transparent layer in order not to affect the display effect. In some embodiments of the present application, the target material layer 20 may include materials such as organic salts, organic small molecules, polymers, and nanotubes. By controlling the molecular structure of the target material layer 20, it is possible to selectively absorb light waves of a specific wavelength and re-emit light waves of another wavelength, while allowing visible light to pass through without hindrance. Accordingly, the target material layer 20 may be transparent so as not to affect the display effect.
For example, the layer of target material 20 may absorb ultraviolet light within a first predetermined wavelength range and/or infrared light within a second predetermined wavelength range, i.e., the first light wave includes ultraviolet light within the first predetermined wavelength range and/or infrared light within the second predetermined wavelength range.
As one example, the target material may absorb ultraviolet light within a first predetermined wavelength range and then emit infrared light within a third predetermined wavelength range. The target material may absorb infrared light of a second predetermined wavelength range and then emit infrared light of a third predetermined wavelength range. Wherein the wavelength of the third predetermined wavelength range is greater than the wavelength in the second predetermined wavelength range. That is, the target material layer 20 may absorb infrared light and emit deeper infrared light. As an example, the first predetermined wavelength range is from 10 nanometers (nm) to 400 nm.
When photons are incident on the surface of the photosensitive device, part of the photons excite the photosensitive material to generate electron-hole pairs, so as to form a current, and the ratio of the collected electrons (subjected to processes such as internal electron-hole recombination) to the number of all incident photons is called External Quantum Efficiency (EQE).
As shown in fig. 3, natural light is incident to the target material layer 20. Natural light includes Visible (VIS), ultraviolet, and Near Infrared (NIR) light. The target material layer 20 allows some visible light to pass through without obstruction, so the EQE corresponding to visible light with wavelengths of 400nm to 650nm has a small value, i.e. light in this range may not be absorbed by the target material layer, and thus penetrates through the target material layer 20. The target material layer 20 may selectively absorb ultraviolet light or infrared light of incident light and emit infrared light of a deeper wavelength. Infrared light having a wavelength around 760nm corresponds to a higher EQE value, i.e., the target material layer 20 emits infrared light having a wavelength around 760 nm.
In embodiments of the present application, the target material layer may let some visible light pass through unhindered, i.e. the target material layer is a transparent layer. If the target material layer is a transparent layer, the display of the display panel can not be influenced, and the display effect is improved.
In the embodiments of the present application, the first photoelectric converter and the second photoelectric converter disposed on the outer peripheral side of the target material layer may receive the second light wave emitted from the side surface of the target material layer and convert the light energy of the second light wave into electric energy.
In some embodiments of the present application, the first photoelectric converter and the second photoelectric converter may each be a photodiode, a photomultiplier tube, or the like photoelectric converter.
In some embodiments of the present application, the screen of the electronic device can receive light uniformly around the screen under sufficient light conditions. The target material layer converts a first light wave that is perpendicular to a screen of the electronic device into a second light wave that propagates parallel to the screen direction and directs the second light wave into the first and second photoelectric converters. If the screen of the electronic device is not touched, the incident light uniformly irradiates the screen of the electronic device, and the intensity of the light received by each first photoelectric converter and each second photoelectric converter is equal, so that the electrical signals output by each first photoelectric converter and each second photoelectric converter are the same.
However, when the user performs a touch operation on the screen of the electronic device, the finger may cover a portion of the screen area, and the light may not irradiate the area covered by the finger on the screen. As shown in fig. 4, the shaded area in fig. 4 is the touch area of the user on the screen, and since the touch area is blocked, the intensity of the light received by the target area corresponding to the touch area in the target material layer will be reduced. When the target area of the target material layer cannot receive light, the first photoelectric converter with the affected electric signal exists in the first photoelectric conversion unit, and the second photoelectric converter with the affected electric signal exists in the second photoelectric conversion unit. The touch area can be determined according to the first electrical signal output by the first photoelectric converter and the second electrical signal output by the second photoelectric converter.
As shown in fig. 1, the touch area method 100 provided by the present application includes:
step 120 of determining a first target photoelectric converter in the first photoelectric conversion unit in which the first electric signal is minimum and a second target photoelectric converter in the second photoelectric conversion unit in which the second electric signal is minimum;
In an embodiment of the present application, a first electrical signal output by the first photoelectric converter and a second electrical signal output by the second photoelectric converter may be collected by the electrical signal sensor.
As one example, the first electrical signal may be a current output by the first photoelectric converter. The second electrical signal may be a current output by the second photoelectric converter.
If the screen of the electronic device is not touched, the first electric signal output by each first photoelectric converter and the second electric signal output by each second photoelectric converter are equal. Therefore, if the first electrical signals output by each first photoelectric conversion device are equal and the second electrical signals output by each second photoelectric conversion device are equal, it can be determined that the screen of the electronic device is not touched.
If the screen of the electronic device is touched, the target area corresponding to the position of the touch area of the screen in the target material layer cannot receive light, so that a part of the first electrical signals output by the first photoelectric converter in the first photoelectric conversion unit is reduced, and a part of the second electrical signals output by the second photoelectric converter in the second photoelectric conversion unit is reduced.
It should be noted that since the loss of light gradually increases with the increase of the propagation distance, the first electrical signal of the first photoelectric converter closest to the target region in the target material layer in the first photoelectric conversion unit is most affected, that is, the first electrical signal is most reduced, because the target region in the target material layer is blocked. The second electrical signal of the second photoelectric converter closest to the target area in the target material layer in the second photoelectric conversion unit is most affected, i.e., the second electrical signal is most reduced.
Referring to fig. 2, the first photoelectric converter in the first photoelectric conversion unit closest to the target area in the target material layer is a first photoelectric converter capable of receiving light emitted from a side surface opposite to the target area in the second direction. The second photoelectric converter in the second photoelectric conversion unit closest to the target region in the target material layer is a second photoelectric converter of the light emitted from the side opposite to the target region in the first direction.
In some embodiments, the first photoelectric conversion unit, the second photoelectric conversion unit, and the target material layer are in the same plane. Referring to fig. 4, the first photoelectric converter in the first photoelectric conversion unit closest to the target area in the target material layer is the first photoelectric converter X facing the target area in the second direction. The second photoelectric converter closest to the target area in the target material layer in the second photoelectric conversion unit is the second photoelectric converter Y facing the target area in the first direction.
Therefore, in order to determine the touch area, it is necessary to determine the first photoelectric converter with the most affected first electrical signal in the first photoelectric conversion unit and the second photoelectric converter with the most affected second electrical signal in the second photoelectric conversion unit.
In step 120, based on the acquired first electrical signal output by each first photoelectric converter in the first photoelectric conversion unit, the first photoelectric converter with the smallest first electrical signal in the first photoelectric conversion unit, that is, the first photoelectric conversion device with the largest influence on the first electrical signal due to the touch area being blocked, that is, the first target photoelectric conversion device, may be determined. Similarly, based on the acquired second electrical signals output by each second photoelectric converter in the second photoelectric conversion unit, the second photoelectric converter in the second photoelectric conversion unit with the smallest second electrical signal, that is, the second photoelectric conversion device in which the second electrical signal is most affected due to the touch area being blocked, that is, the second target photoelectric conversion device, may be determined.
In the embodiment of the application, due to the influence of the touch area, the first electrical signal of the first target photoelectric converter in the first photoelectric conversion unit is influenced most, and the second electrical signal of the second target photoelectric converter in the second photoelectric conversion unit is influenced most, so in step 130, the touch area of the electronic device may be determined according to the position information of the first target photoelectric converter and the position information of the second target photoelectric converter.
According to the touch area method, the touch area can be determined through the first electric signal output by the first photoelectric converter and the second electric signal output by the second photoelectric converter without depending on a conductor, the problem of mistaken touch or touch failure is reduced, the determination of the touch area can be realized as long as a light source is incident on a screen of the electronic equipment, and the reliability is higher.
In some embodiments of the present application, step 130 comprises: determining a first pixel region corresponding to the position information of the first target photoelectric converter and a second pixel region corresponding to the position information of the second target photoelectric converter based on a preset corresponding relationship between the position information of the photoelectric converters and the pixel regions; and determining the overlapping area of the first pixel area and the second pixel area as a touch area.
In the embodiments of the present application, the position information of the first target photoelectric converter is the position information of the first target photoelectric converter in the first photoelectric conversion unit in which it is located. The position information of the second target photoelectric converter is the position information of the second target photoelectric converter in the second photoelectric conversion unit where the second target photoelectric converter is located.
In the embodiment of the present application, the correspondence relationship of the position information of the photoelectric converter and the pixel region may be defined in advance. In the embodiment of the present application, since the number of the first photoelectric converters in one first photoelectric conversion unit may be different from the number of pixels in the first direction, and the number of the second photoelectric converters in one second photoelectric conversion unit may be different from the number of pixels in the second direction, the pixel region corresponding to each first photoelectric converter and each second photoelectric converter may be predefined in advance according to the value of M, N and the number of pixels in the first direction and the number of pixels in the second direction in the screen of the electronic device.
Then, based on a preset correspondence relationship between the positional information of the photoelectric converters and the pixel regions, a first pixel region corresponding to the positional information of the first target photoelectric converter and a second pixel region corresponding to the positional information of the second target photoelectric converter are determined.
Due to the influence of the touch area, the first electrical signal of the first target photoelectric converter in the first photoelectric conversion unit is influenced most, and the second electrical signal of the second target photoelectric converter in the second photoelectric conversion unit is influenced most, so that the overlapping area of the first pixel area and the second pixel area is the touch area.
Referring to fig. 4, the electronic device includes one first photoelectric conversion unit and one second photoelectric conversion unit. The first photoelectric conversion unit includes first photoelectric converters arranged in a direction parallel to a short side direction of the screen of the first photoelectric conversion unit. The second photoelectric conversion unit includes second photoelectric converters arranged in a direction parallel to a long side of a screen of the electronic apparatus. Wherein the first target photoelectric converter in the first photoelectric conversion unit is a first photoelectric converter X. The first pixel region 41 corresponding to the first target photoelectric converter X is a pixel region corresponding to a hatched region in fig. 4. The second target photoelectric converter in the second photoelectric conversion unit is a second photoelectric converter Y. The second pixel region 42 corresponding to the second target photoelectric converter Y is a pixel region corresponding to the well line region in fig. 4. The overlapping area 43 of the first pixel area 41 and the second pixel area 42 is a touch area touched by a user.
It is worth mentioning that, in the first photoelectric conversion unit, the number of the first photoelectric converters having the smallest first electrical signal may be plural, that is, the number of the first target photoelectric converters in one first photoelectric conversion unit may be plural. Similarly, in the second photoelectric conversion unit, the number of second photoelectric converters having the smallest second electrical signal may be plural, that is, the number of second target photoelectric converters in one second photoelectric conversion unit may be plural. Then, in step 130, a union of overlapping areas of the first pixel area corresponding to each first target photoelectric converter and the second pixel area corresponding to each second target photoelectric converter is used as a touch area.
It should be noted that, if there are a plurality of first photoelectric conversion units and a plurality of second photoelectric conversion units, as shown in fig. 3, there is a first target photoelectric converter in each first photoelectric conversion unit and a second target photoelectric converter in each second photoelectric conversion unit. In step 130, a common overlapping area of the first pixel areas corresponding to all the first target photoelectric converters and the second pixel areas corresponding to all the second target photoelectric converters is used as a touch area.
In the embodiment of the application, based on the preset corresponding relationship between the positions of the photoelectric converters and the pixel areas, the first pixel area corresponding to each first target photoelectric converter and the second pixel area corresponding to each second target photoelectric converter can be accurately obtained, so that the touch area can be accurately determined, and the accuracy of detecting the touch area is improved.
In some embodiments of the present application, a user may perform a continuous touch operation, such as a sliding input or a continuous-click input, and in order to more accurately determine characteristic information of the touch input of the user, in step 110, the first electrical signal output by each first photoelectric converter and the second electrical signal output by each second photoelectric converter are acquired at preset time intervals in a preset time period. That is, after every preset time interval, the first electrical signal output by each first photoelectric converter and the second electrical signal output by each second photoelectric converter are newly acquired.
In the embodiment of the application, one touch area may be determined based on each acquired first electrical signal output by each first photoelectric converter and each acquired second electrical signal output by each second photoelectric converter.
Therefore, after step 130, the touch area method provided by the present application further includes step 140 of determining characteristic information of the touch input based on each touch area determined within a preset time period.
In an embodiment of the present application, the characteristic information of the touch input is information that can be used to reflect the characteristics of the touch input. For example, the characteristic information of the touch input may include a type of the touch input (e.g., a type of a click input, a slide input, etc.), a trajectory of the touch input (e.g., an S-shape, an L-shape, etc.), an input direction of the touch input (e.g., an up-slide, a down-slide, etc.), and the like.
In some embodiments, step 140 comprises: determining the type of touch input based on the number of the touch areas determined in a preset time period and the position information of each touch area; the characteristic information includes a type of the touch input.
As an example, if the position information of each touch area determined within the preset time period is the same, and the number of touch areas determined within the preset time period is P, the type of the touch input may be a long press input or a P-time click input. For example, if only one touch area is obtained within a preset time period, it may be determined that the touch input is a single-click input. P is a positive integer greater than or equal to 1.
In other embodiments, if the position information of each touch area determined within the preset time period is different, and the number of the touch areas determined within the preset time period is Q, the type of the touch input may be a sliding input. Q is a positive integer greater than 1.
In some embodiments, step 140 comprises: determining characteristic information of touch input based on the position information of each touch area determined in a preset time period; wherein the characteristic information comprises at least one of: touch trajectory, touch direction.
For example, referring to fig. 5, if steps 110 to 130 are performed 3 times within a preset time period, 3 touch areas are determined. In the process of determining the touch area for the 3 times, the determined first target photoelectric converters are the same and are all the first photoelectric converters X1 in fig. 5, and the first pixel area 51 corresponding to the first photoelectric converter X1 is an oblique line area shown in fig. 5. However, the second target photoelectric converters determined in the process of determining the touch area for the 3 times are different, and are respectively the second photoelectric converter Y1, the second photoelectric converter Y2, and the second photoelectric converter Y3 shown in fig. 5. Wherein each second target photoelectric converter has a respective corresponding second pixel region 52. The overlapping area of the first pixel area 51 and the second pixel area 52 is a touch area 53. Wherein the pixel coordinates of each of the determined 3 touch areas 53 on the image coordinate axis parallel to the first direction are the same, but the pixel coordinates of each of the touch areas on the image coordinate axis parallel to the second direction are different, and as the touch area determination time gradually increases, the values of the pixel coordinates of the touch areas on the image coordinate axis parallel to the second direction gradually increase, and then the touch input may be determined as a slide input in the second direction.
