Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
In the related art, in order to implement the distance detection function in the electronic device, two openings are usually disposed in a partial area of the front cover of the electronic device except for the display area, a transmitting unit of the distance sensor is disposed below the first opening, and a receiving unit of the distance sensor is disposed below the second opening. When the distance detection is carried out, the transmitting unit transmits a detection signal through the first opening, detects a reflection signal acting on a target object based on the detection signal through the second opening, and carries out the distance detection according to the detection signal and the reflection signal.
The transmitting unit and the receiving unit need to be disposed in the housing of the electronic device, and therefore occupy the space in the housing of the electronic device, reduce the available space of other functional elements, and are not conducive to the lightness and thinness of the electronic device.
In addition, the first opening and the second opening occupy a certain area on the front cover of the electronic device, so that the occupied area of the display area on the front cover is limited, and the screen occupation ratio of the electronic device is reduced.
Further, because the receiving unit needs just to receive the reflected signal through the second trompil, so in order to guarantee the effect of distance detection, set up to the position of transmitting unit and receiving unit and have higher requirement, and this distance inductor can carry out the working area that the distance detected less, is difficult to guarantee the degree of accuracy and the user experience of distance detection.
FIG. 1 is a schematic diagram illustrating an electronic device 100 in accordance with an example embodiment. Referring to fig. 1, the electronic device 100 includes:
a transmitting unit 120 for transmitting a detection signal;
a display region 130 including a plurality of pixel units; the pixel unit is used for generating an electric signal based on a reflected signal returned by a detection signal acting on a target object in a display gap during display or in a non-display period;
an output circuit 140 connected to the display region 130, for outputting the electric signal; wherein the electrical signal is used to determine the relative positional relationship between the target object and the electronic device 100.
For example, the relative positional relationship between the target object and the electronic device 100 may include: a distance between the target object and the electronic device 100, and/or an angle between a plane in which the target object is located and a plane in which the electronic device 100 is located.
Taking a cylinder as an example of the target object, a relative position relationship between the target object and the electronic device 100 is specifically described. The cylinder includes first surface, second surface and third surface, and first surface and second surface are the circular surface, and the third surface is the annular surface of perpendicular to first surface and second surface respectively.
When the first surface of the cylinder is parallel to the display area 130 of the electronic device 100, the first surface of the cylinder faces the display area 130, and the second surface of the cylinder is away from the display area 130, the relative positional relationship between the cylinder and the electronic device 100 includes a perpendicular distance between the first surface of the cylinder and the display area 130 of the electronic device 100.
When the second surface of the cylinder is parallel to the display area 130 of the electronic device 100, the second surface of the cylinder faces the display area 130, and the first surface of the cylinder is away from the display area 130, the relative positional relationship between the cylinder and the electronic device 100 includes a perpendicular distance between the second surface of the cylinder and the display area 130 of the electronic device 100.
When a first included angle exists between the plane of the second surface of the cylinder and the plane of the display area 130 (that is, the plane of the second surface of the cylinder is not parallel to the plane of the display area 130), the second surface of the cylinder faces the display area 130, and the first surface of the cylinder is far away from the display area 130, the relative positional relationship between the cylinder and the electronic device 100 includes the first included angle between the plane of the second surface of the cylinder and the plane of the display area 130.
When there is relative motion between the cylinder and the electronic device, the relative positional relationship between the cylinder and the electronic device 100 may further include: the cylinder and the electronic device are close to each other, or the cylinder and the electronic device are far from each other, etc.
The transmitting unit 120 is a transmitting unit capable of transmitting an infrared signal. At this time, the detection signal is an infrared signal. Taking the example of the transmitting unit transmitting the infrared signal, the target object located in the field angle range of the transmitting unit 120 can reflect the received infrared signal to generate the reflected signal.
The pixel unit includes: an Organic Light Emitting Diode (OLED) unit.
During display, the pixel units of the display region 130 have an emission period and a display gap. Illustratively, the pixel cell in the emission period generates a light signal according to the driving signal, and the pixel cell in the display gap suspends generating the light signal. It is understood that the display gap is located between two adjacent light emission periods during display.
Due to the persistence of vision, in the display gap between two adjacent light-emitting periods, the visual effect of the optical signal generated by the pixel unit in the previous light-emitting period on the retina of the human eye is still persisted in the brain of the human eye in the display gap, i.e. the user thinks that the display region 130 is still being displayed in the display gap during the display.
Therefore, the pixel unit can generate an electric signal based on the detection signal acting on the reflected signal returned by the target object in the display gap during the display period, so that the electronic device 100 can realize the relative position relation detection function while displaying information.
During the non-display period, the pixel units of the display area 120 do not generate light signals. At this time, the detection signal emitted by the emitting unit 120 acts on the target object, the target object reflects the detection signal, a reflection signal having a propagation direction different from that of the detection signal is generated, and at least a part of the reflection signal propagates toward the display area 130. In the display area 130, the pixel unit receiving the reflection signal generates an electrical signal under the excitation of the reflection signal.
Illustratively, the signal value of the electrical signal may be used to characterize the intensity of the reflected signal received by the pixel cell that generated the electrical signal. Specifically, the signal value of the electrical signal may be positively correlated with the intensity of the reflected signal received by the pixel unit.
Compared with the electronic equipment additionally provided with a receiving unit for receiving the reflected signal of the infrared signal acting on the target object and provided with the opening corresponding to the receiving unit on the shell of the electronic equipment to allow the receiving unit to receive the reflected signal, the embodiment of the disclosure receives the reflected signal by using the pixel unit of the display area, generates the electric signal and determines the relative position relationship between the target object and the electronic equipment according to the electric signal, and a special receiving unit is not required to be arranged in the electronic equipment, so that the hardware cost of the electronic equipment is reduced.
Moreover, since the area of the display area that can receive the reflected signal is larger than the receiving area of the specially-arranged receiving unit, the scheme of the embodiment of the disclosure can expand the range of relative position detection.
In some embodiments, as shown in fig. 2, the electronic device 100 may further include:
and the detection module 150 is connected to the output circuit 140, and is configured to determine a relative positional relationship between the target object and the electronic device 100 according to a position of a pixel unit generating the electrical signal and a signal value of the electrical signal when the electrical signal is detected.
The detecting module 150 may include: the electronic device 100 may be an onboard processor or an additionally provided processor chip. For example, the detecting module 150 may be a Central Processing Unit (CPU) of the electronic apparatus 100.
The position parameters of the pixel units and the transmission lines of the output circuit 140 for transmitting the electrical signals from the pixel units to the detection module 150 may have a corresponding relationship, and the corresponding relationship may be stored in the detection module 150 in advance. When the detection module 150 detects the electrical signal, the detection module 150 can obtain the position parameter of the pixel unit generating the electrical signal according to the transmission line detecting the electrical signal and the corresponding relationship. Here, the position parameter is used to indicate the position of the pixel unit in the display area 130.
The detection module that this disclosed embodiment set up through the position of the pixel element that combines to produce the electric signal and the signal value of electric signal, can improve the degree of accuracy that relative position relation detected.
In some embodiments, the detection module 150 is configured to determine the relative position relationship between the target object and the electronic device 100 according to the position of the electrical signal having the signal value greater than the preset signal value and the pixel unit generating the electrical signal having the signal value greater than the preset signal value.
In the external environment where the electronic apparatus 100 is located, there are generally other objects capable of radiating infrared rays to the outside. When the other object is not the target object and the infrared rays radiated by the other object move to the display area 130, the pixel units of the display area 130 are also excited to generate weak electrical signals, thereby causing interference in detecting the relative position relationship between the target object and the electronic device 100. It will be appreciated that, in general, the signal value of the electrical signal generated by the pixel element when excited by said other object is smaller than the signal value of the electrical signal generated by the pixel element based on said reflected signal.
Therefore, in the present disclosure, the detection module 150 generates the ranging signal according to the electrical signal having the signal value greater than the preset signal value, and can identify the pixel unit generating the electrical signal based on the reflection signal, reduce the interference of the other objects in the external environment on the detection of the relative position relationship between the target object and the electronic device 100, and improve the accuracy of the detection
Fig. 2 shows a positional relationship between a target object and an electronic device. As shown in fig. 2, the pixel units located in the shadow area of the display area 130 receive the reflection signal to generate the signal value of the electrical signal, and the signal value of the electrical signal generated by the pixel units is greater than the preset signal value.
In some embodiments, the detection module 150 is configured to determine the shape of the target object according to the positions of the plurality of pixel units generating the electrical signals and the signal values of the electrical signals.
Take the example that the detection signal is an infrared signal. In the field angle of the infrared signal emitted by the emitting unit 120, the emitted infrared signal has different propagation directions, and therefore, the infrared signals with different propagation directions have different incident angles at the same position of the target object, and therefore, the reflected signals with different reflection angles are generated at the same position of the target object.
The paths of the reflection signals with different reflection angles generated at the same position of the target object moving to the display area are different, so that the reflection signals with different reflection angles generated by the reflection at the same position of the target object are received by different pixel units, and the intensities of the reflection signals with different reflection angles generated by the reflection at the same position of the target object and received by different pixel units are also different. Therefore, the intensity of the reflected signal received by the pixel units at different positions is different, and the signal value of the generated electric signal is also different.
Therefore, the detection module can determine the projection outline of the target object to the display area according to the positions of the pixel units generating the electric signals and the values of the electric signals. Wherein the contour is the same or similar to the actual shape of the target object.
In the embodiment of the disclosure, the detection module 150 may determine the shape of the target object according to the positions of the plurality of pixel units generating the electrical signals and the signal values of the electrical signals, so as to lay a foundation for controlling the electronic device 100 to execute a predetermined function (for example, a function of unlocking the electronic device based on gesture recognition) based on the shape of the target object, and facilitate enrichment of user experience.
The predetermined function may include: the electronic apparatus 100 is switched from the locked state to the unlocked state, or the electronic apparatus 100 is switched from the unlocked state to the locked state.
Illustratively, when the electronic device 100 is in the locked state, the user cannot browse and read data information stored by the electronic device 100. For example, the user cannot browse photos stored by the electronic device 100.
Illustratively, when the electronic device 100 is in the unlocked state, the user may browse and read data information stored by the electronic device 100. For example, the user may browse through photos stored by the electronic device 100.
When the detection module 150 determines that the similarity between the shape of the target object and the first preset shape is greater than the similarity threshold, the detection module 150 controls the electronic device 100 to switch from the locked state to the unlocked state. Here, the first predetermined shape may be pre-stored in the detection module 150, or may be pre-stored in a storage module of the electronic device 100; the target object may be a gesture of the user with a finger, and thus, a function of unlocking the electronic device according to a gesture of the user may be realized.
When the detection module 150 determines that the similarity between the shape of the target object and the first preset shape is smaller than the similarity threshold, the detection module controls the electronic device to keep the current state.
For another example, when the detection module 150 determines that the similarity between the shape of the target object and the second preset shape is greater than the similarity threshold, the detection module 150 controls the electronic device 100 to switch from the unlocked state to the locked state. Here, the second predetermined shape may be pre-stored in the detection module 150, or may be pre-stored in a storage module of the electronic device 100; the target object can be a gesture of the user with fingers, and therefore the function of locking the electronic equipment according to the gesture of the user can be achieved.
When the detection module 150 determines that the similarity between the shape of the target object and the second preset shape is smaller than the similarity threshold, the detection module controls the electronic device to keep the current state.
In some embodiments, the detection module 150 is further configured to determine the motion trajectory data of the target object according to a trend of signal value changes of the electrical signals generated by the pixel units.
Here, the motion trajectory may include: a first trajectory perpendicular to the display area 130 and/or a second trajectory parallel to the display area 130.
For example, when the target object moves, the relative position between the target object and the electronic device 100 changes, and therefore, the distance that the detection signal travels in the space and the distance that the reflection signal travels may both change, and the position of the pixel unit that receives the reflection signal and the intensity of the reflection signal received by the pixel unit may both change.
For example, when the target object approaches the electronic device 100 along the first trajectory and the vertical distance between the target object and the electronic device 100 decreases, the intensity of the reflected signal received by the pixel unit increases, and thus the signal value of the electrical signal generated by the pixel unit gradually increases. Here, the first trajectory may be perpendicular to a plane in which the display area 130 is located.
Similarly, when the target object moves away from the electronic device 100 along the first trajectory and the vertical distance between the target object and the electronic device 100 increases, the intensity of the reflected signal received by the pixel unit decreases, and thus the signal value of the electrical signal generated by the pixel unit gradually decreases.
For example, the detection module 150 may further determine the motion trajectory data of the target object according to a signal value variation trend of the electrical signal generated by the pixel unit and a position of the pixel unit generating the electrical signal.
For example, when the target object moves along the second trajectory, the vertical distance between the target object and the electronic device 100 does not change, but the position of the pixel unit receiving the reflected signal changes, that is, the position of the pixel unit generating the electric signal changes. In particular, the second trajectory may be parallel to a plane in which the display area 130 is located.
As another example, when the target object moves along the third trajectory and the target object gradually approaches the electronic device 100, the position of the pixel generating the electrical signal may change and the signal value of the electrical signal increases. When the target object moves along the third trajectory and the target object is far from the electronic device 100, the position of the pixel generating the electrical signal changes and the signal value of the electrical signal decreases. Here, an included angle exists between a plane where the third track is located and a plane where the display area is located, and the included angle between the plane where the third track is located and the plane where the display area is located is not a right angle.
In the embodiment of the present disclosure, the detection module 150 may determine the motion trajectory data of the target object according to the signal value variation trend of the electrical signal generated by the pixel unit, so as to lay a foundation for controlling the electronic device 100 to execute a predetermined function based on the motion trajectory of the target object, and facilitate enriching the user experience.
Here, the predetermined function may further include: change the volume of the electronic device 100, slide the display interface of the electronic device 100, or the like.
For example, when the electronic device 100 plays a video through the display area 130 and the detection module 150 determines that the motion trajectory data of the target object indicates that the target object moves in the first direction, the volume of the electronic device 100 is increased.
When the electronic device plays a video through the display area 130 and the detection module 150 determines that the motion trajectory data of the target object indicates that the target object moves in the direction opposite to the first direction, the volume of the electronic device 100 is decreased.
The first direction may include: pointing in the direction of the top bezel of the electronic device 100 from the bottom bezel of the electronic device 100.
In some embodiments, the detection module 150 is further configured to control the electronic device 100 to switch from the screen-off state to the screen-on state when the motion trajectory data indicates that the target object is close to the electronic device 100;
