Detailed Description

The technical solutions in the embodiments of the present application will be described clearly 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 that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present disclosure.

It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. 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.

The following describes in detail a control method of a photosensitive sensor and an electronic device provided in the embodiments of the present application with reference to the accompanying drawings.

Referring to fig. 1, fig. 1 is a schematic view illustrating an assembly of a conventional micro-slit photosensor in an electronic device, the micro-slit photosensor in fig. 1 employs a single transmitting tube capable of integrally transmitting a light signal, the electronic device is provided with a light transmitting hole 07 and a light receiving hole 08, a transmitting tube 05 of a transmitting assembly 02 is disposed right below the light transmitting hole 07, and a receiving tube is disposed right below the light receiving hole 08. The optical path of the optical signal emitted by the transmitting tube 05 is: the light signal is transmitted to the environment through the light emitting hole 07, and after being reflected by a reflector in the environment, the light signal passes through the light receiving hole 08 and is finally received by the receiving module. The influence of temperature on the optical signal can be used to detect the ambient temperature according to the intensity of the optical signal received by the receiving tube, or the influence of distance on the propagation of the optical signal can be used to measure the distance between a reflector and the electronic device in the environment according to the intensity of the optical signal received by the receiving tube. However, since the opening of the light emitting hole 07 or the light receiving hole 08 is small, and there may be errors in assembling the micro-slit photosensitive sensor, for example, there is a tolerance between the emitting tube 05 and the light emitting hole 07 in the Y direction, which may cause a part of the optical path of the emitting tube 05 to be blocked by the electronic device itself, and the light signal generated by the blocked emitting tube 05 may interfere with the inside of the electronic device, increasing the noise floor of the sensor itself, and thus affecting the performance of the sensor.

Thus, in order to solve the above-mentioned problems, the present embodiment provides a control method of a photosensor 01, which is applicable to the photosensor 01 provided in the present embodiment, and referring to fig. 2, the photosensor 01 includes a transmitting element 02 and a receiving element 03, the transmitting element 02 is used for transmitting an optical signal, and the receiving element 03 is used for receiving an optical signal. The photosensor 01 is disposed inside a housing of the electronic apparatus, on which a light emitting hole 07 corresponding to the emitting component 02 and a light receiving hole 08 corresponding to the receiving component 03 shown in fig. 1 are disposed. For example, the emitting assembly 02 is disposed inside the housing at a position below the light emitting hole 07 to facilitate the emission of the light signal; the receiving module 03 is disposed inside the housing at a position below the light receiving hole 08 to facilitate the reception of the optical signal.

The electronic device can be an intelligent terminal device such as a mobile phone, a computer, a tablet computer and the like, when the electronic device is a mobile phone, the shell 09 can be a cover plate of a mobile phone main body, the cover plate and the screen 10 are combined to form the upper surface of the mobile phone, and the photosensitive sensor 01 is arranged at the edge of the screen 10.

Wherein, referring to fig. 2, the launching assembly 02 in the embodiment includes at least two launching tube sets 04, each launching tube set 04 includes at least one launching tube 05, for example, the launching assembly 02 includes two launching tube sets 04, each launching tube set 04 includes one launching tube 05, then the launching assembly 02 includes 2 launching tubes, and the opening and closing of the two launching tubes can be controlled respectively.

For another example, referring to fig. 3, the launching assembly 02 includes 2 launching tube groups 04, each of which includes 3 launching tubes 05, and then the launching tube group 04 includes 6 launching tubes, so that the launching tubes in each launching tube group 04 can be customized by controlling the launching tubes 05 of the same launching tube group to be opened and closed at a time.

The emitting tube 05 may be one of a semiconductor light source, a light emitting diode, a laser diode and an infrared emitting diode, the receiving assembly 03 includes a receiving tube 06, and the receiving tube 06 may be a photodiode and a phototransistor.

It should be noted that, considering that the space available for installing the photosensitive sensor 01 on the housing of the electronic device is narrow, and therefore, the tolerance generated by the photosensitive sensor 01 when being assembled with the electronic device is mostly the tolerance in the Y direction, in this embodiment, the emitting tubes 05 of each emitting tube group 04 may form an array, that is, when the emitting assembly 02 includes two emitting tube groups 04, and each emitting tube group 04 includes one emitting tube 05, the emitting assembly 02 is a 2 × 1 emitting tube array; when the launching assembly 02 comprises 3 launching tube groups 04, each launching tube group 04 comprising 2 launching tubes 05, the launching assembly 02 is a 3 x 2 array of launching tubes. So that a single or entire column of emitter tubes obscured by the housing can be shut off by individually controlling the closure of the emitter tubes 05 of each column.

For the above photosensitive sensor 01, the present embodiment provides a control method of the photosensitive sensor, which includes the following steps with reference to fig. 4:

step 1100, controlling at least two transmitting tube sets 04 to sequentially transmit optical signals.

In order to detect whether the emitting tube 05 in the emitting assembly 02 is shielded by the housing when the photosensitive sensor 01 is assembled, the emitting tube group of each emitting tube group needs to be detected, and the detection method comprises the following steps: and controlling at least two emission tube groups 04 to sequentially emit light signals according to the set shielding detection sequence, wherein under the condition that the emission tube groups comprise at least two emission tubes, the emission tubes 05 in the same emission tube group 04 have the same detection sequence. That is, all the fire tubes 05 in each fire tube group are controlled to be simultaneously opened or closed.

In a practical example, when the transmitting assembly 02 includes 5 transmitting tube groups 04 and there is only one transmitting tube in each transmitting tube group 04, that is, the transmitting assembly 02 has a total of 5 transmitting tubes, the 5 transmitting tubes may be aligned in an array manner or may not have a specific setting bit. The embodiment may sequentially control the opening and closing of the 5 transmitting tubes, for example, when the first transmitting tube is opened, the other transmitting tubes are kept closed, after the optical signal of the first transmitting tube is received, the first transmitting tube is closed, the second transmitting tube is opened, and the process is sequentially cycled to respectively obtain the optical signal of each transmitting tube 05 when the transmitting tube is opened.

In a practical example, when the launching assembly 02 includes 3 launching tube groups 04 and there are 2 launching tubes in each launching tube group 04, that is, the launching assembly 02 has a total of 6 launching tubes, the 3 launching tube groups 04 may be aligned in an array or may not have a specific setting. The present embodiment can obtain the light signals of the emitting tubes 05 in each emitting tube group when the emitting tubes 05 are opened by controlling the opening and closing of every two emitting tubes 05 in the 3 emitting tube groups 04 in sequence, for example, when 2 emitting tubes 05 in the first emitting tube group are opened, keeping the emitting tubes 05 in the other emitting tube groups closed, after receiving the light signals of the first emitting tube group, closing the emitting tubes 05 in the first emitting tube group, opening the emitting tubes 05 in the second emitting tube group, and circulating in sequence.

In this embodiment, the larger the number of emitting tubes in each emitting tube group, the greater the intensity of the light signal, and thus the greater the intensity of the received light signal, therefore, the number of emitting tubes in each emitting tube group is preferably greater than 1, so as to improve the detection effect.

Step 1200, obtaining a first voltage value output by the receiving component.

In this embodiment, the photosensitive sensor 01 may be a device that converts an optical signal into an electrical signal, and therefore, after controlling the transmitting tube set 04 in the current detection order to send an optical signal, the optical signal received by the receiving component 03 may be converted into a corresponding electrical signal, so as to output a first voltage value, where the first voltage value represents the strength of the optical signal received by the receiving component 03.

In one possible example, the receiving assembly may be provided with a photoelectric conversion circuit, and after the receiving tube in the receiving assembly receives the optical signal, the photoelectric conversion circuit converts the optical signal into a corresponding voltage value.

Step 1300, determining a target launching tube shielded by the shell in the launching tube group according to the first voltage value.

Under the condition that the number and the emission intensity of the emission tubes are fixed and the emission tubes are not shielded by the shell, the light signals received by the receiving tubes comprise light signals received by the receiving tubes through the light receiving holes and light signals generated by bottom noise in the shell, the distance between an external emitting object and the photosensitive sensor is fixed, and under the condition that the external temperature is not changed, namely under the condition that environmental variables are not changed, the intensity of the light signals received by the receiving tubes can be regarded as unchanged, so that the voltage value output by the receiving tubes is also unchanged.

In this embodiment, because the optical signal is transmitted in a relatively small space when the transmitting tube is shielded by the housing, the intensity of the optical signal is greater than the intensity of the optical signal reflected by the scattered air, that is, if the transmitting tube is shielded, the total intensity of the optical signal received by the receiving tube is increased. Therefore, in this embodiment, in the case that the first voltage value is greater than the first preset threshold, it is determined that the optical signal emitted by the transmitting tube group is blocked by the casing, and at this time, the target transmitting tube is one or more transmitting tubes in the blocked transmitting tube group.

For example, the transmitting assembly 02 includes 3 transmitting tube groups 04, each transmitting tube group 04 includes 2 transmitting tubes, the 2 transmitting tubes simultaneously transmit light signals, when a first group of transmitting tubes transmits light signals, and when other transmitting tubes are closed, a first voltage value output by the receiving tube is greater than a first preset threshold, which indicates that the transmitting tube of the group is blocked by the housing, and then the transmitting tube of the first group is determined to be a target transmitting tube.

For another example, the transmitting assembly 02 includes 3 transmitting tube groups 04, each transmitting tube group 04 has 2 transmitting tubes, the 2 transmitting tubes in the same group are respectively controlled to sequentially transmit optical signals, when the first transmitting tube in the group transmits an optical signal, and the second transmitting tube is turned off, the first voltage value output by the receiving tube is a, when the first transmitting tube in the group is turned off, and the second transmitting tube transmits an optical signal, the first voltage value output by the receiving tube is B, a is equal to the first preset threshold, and B is greater than the first preset threshold, then the second transmitting tube in the group is determined as the target transmitting tube.

In this embodiment, since the optical signal received by the receiving component includes the optical signal received by the receiving tube through the light receiving hole and the optical signal received by the receiving tube inside the housing, the first voltage value includes a voltage value corresponding to the optical signal received by the receiving tube through the light receiving hole and a voltage value corresponding to the optical signal received by the receiving tube inside the housing.

And 1400, closing the target transmitting tube.

In this embodiment, because under the condition that the transmitting tube is shielded by the casing, a noise floor is generated inside the photosensor 01, which affects the performance of the photosensor, in this embodiment, the corresponding target transmitting tube is controlled to be in the closed state when the target transmitting tube whose optical signal is shielded by the casing is detected.

For example, when it is detected that the first voltage value output by the receiving component 03 is greater than a first preset threshold, a closing instruction is generated, and after receiving the closing instruction, a chip in the control circuit controls the transmitting tube 05 to be kept closed.

For example, referring to fig. 5, it can be seen that the transmitting assembly 02 includes two transmitting tube sets 04, wherein each transmitting tube set 04 includes 1 transmitting tube 05, and at this time, the transmitting tube 05 located above is shielded by the housing, so that the noise floor inside the photosensor 01 can be reduced by controlling the shielded transmitting tube 05 to be closed.

Referring to fig. 6, fig. 6 shows the steps of the control method of the photosensor according to the present embodiment in practical application, including: each group of transmitting tube group 04 is sequentially opened according to the shielding detection sequence, a first voltage value output by the receiving component 03 is recorded, under the condition that the first voltage value is larger than a first preset threshold value, it is determined that the corresponding opened transmitting tube group 04 is shielded by the shell, the corresponding transmitting tube in the transmitting tube group 04 is closed, under the condition that the first voltage value is smaller than the first preset threshold value, processing is not carried out, the steps are sequentially circulated until the last group of transmitting tube group 04 finishes detection, and therefore the photosensitive sensor 01 has higher performance in normal use.

It can be known from the foregoing embodiment that, in the case that each transmitting tube group 04 in the transmitting assembly 02 of the photosensor 01 only includes one transmitting tube 05 in this embodiment, the control method of this embodiment can implement individual controllability for each transmitting tube 05, and this manner is suitable for a situation where there are tolerances in both the X direction and the Y direction in the assembly of the transmitting assembly 02, for example, in fig. 7, in a situation where the transmitting assembly 02 is inclined with respect to the light emitting hole 07, the performance of the sensor can be improved by individually controlling the blocked transmitting tube 05 to close.

In this embodiment, in the case that each emitting tube group 04 in the emitting assembly 02 of the photosensor 01 includes a plurality of emitting tubes 05, the whole group of each emitting tube group 05 can be controlled, which is suitable for the situation that the assembly of the emitting assembly 02 has a tolerance in the Y direction, for example, in fig. 8, the whole row of emitting tubes 05 of the emitting assembly 02 are all blocked by the housing, the performance of the sensor can be improved by controlling the blocked group of emitting tubes 05 to be closed, and the power consumption can be reduced by controlling the whole group of emitting tubes 05 to be closed.

In order to further reduce the noise floor and improve the performance of the photosensitive sensor 01, in this embodiment, after the target transmitting tube is turned off, the position information of each transmitting tube 05 relative to the receiving assembly 03 is also acquired, so as to adjust the optical signal intensity of each transmitting tube 05 according to the position information.

The position information of each transmitting tube 05 relative to the receiving assembly 03 can be the distance of each transmitting tube 05 relative to the center of the receiving assembly, that is, the position information includes the distance between the transmitting tube 05 and the receiving assembly. The manner of obtaining the position information of each transmitting tube 05 relative to the receiving assembly may be by setting a reflector on the optical signal propagation path of the transmitting tube 05, and detecting the intensity of the optical signal received by the receiving assembly when each transmitting tube 05 is opened to determine the distance between the corresponding transmitting tube 05 and the receiving assembly, for example, the weaker the intensity of the optical signal received by the receiving assembly is, the farther the transmitting tube 05 is from the receiving assembly is represented, and conversely, the stronger the intensity of the optical signal received by the receiving assembly is, the closer the transmitting tube 05 is to the receiving assembly is represented.

In addition, the distance between each of the launching tubes 05 and the launching assembly 02 may be preset according to the fixing position of the launching tube 05 at the time of assembly.

In this embodiment, the intensity of the optical signal of each transmitting tube 05 is adjusted according to the position information, a current control instruction can be generated according to the position information, and the intensity of the optical signal of the transmitting tube 05 is controlled according to the current control instruction. Specifically, the optical signal intensity of the emitter tube within a first distance from the receiver assembly is reduced, and the optical signal intensity of the emitter tube within a second distance from the receiver assembly is increased, wherein the second distance is greater than the first distance.

In this embodiment, because the transmitting tube closer to the receiving component, the optical signal emitted by the transmitting tube is more likely to be received by the receiving tube, and by reducing the intensity of the optical signal of the transmitting tube closer to the receiving component, the probability that the receiving component receives the optical signal inside the housing can be reduced, and the noise of the photosensitive sensor 01 can be reduced. And the intensity of the optical signal of the transmitting tube far away from the receiving component is increased, the transmitting current of the transmitting tube 05 far away from the receiving component is increased, and the detection distance of the photosensitive sensor 01 can be improved.

In an optional example, after the target transmitting tubes are turned off, the transmitting intensity of the transmitting tubes which are not shielded can be increased according to the number of the turned-off target transmitting tubes, for example, when the turned-off target transmitting tubes are one third of the total transmitting tubes, the current light signal intensity of the transmitting tubes which are not shielded can be adjusted to be 2 times of the previous time, and the detection efficiency of the photosensitive sensor can be improved while the light signal intensity is ensured.

The receiving component in this embodiment may be a receiving tube 06, and when the receiving component is a receiving tube 06, the receiving tube 06 receives the optical signal.

Considering that the receiving tube 06 may also be shielded by the housing to affect the performance of the photosensitive sensor 01, the receiving assembly of this embodiment may be at least two individually controllable receiving tubes 06, and when the receiving assembly includes at least two individually controllable receiving tubes 06, after the target transmitting tube is closed, this embodiment may further implement control of the receiving assembly by controlling the opening and closing of each receiving tube 06, so as to reduce power consumption and further improve the performance of the photosensitive sensor 01.

After the target transmitting tube is closed, whether the receiving component is shielded by the shell needs to be detected, and the detection method can detect based on the fact that the intensity of the optical signal received by the receiving tube 06 is different between the case that no reflector exists outside the electronic device and the case that a reflector exists.

In this embodiment, the detection method includes: acquiring a second voltage value and a third voltage value output by the receiving assembly, and detecting whether the receiving tube is shielded by the shell or not according to the difference value of the second voltage value and the third voltage value; and controlling the corresponding receiving pipe to be in a closed state under the condition that the receiving pipe is shielded by the shell. The second voltage value is a voltage value output by the receiving component under the condition that no reflector exists outside the electronic device, and the third voltage value is a voltage value output by the receiving component under the condition that the reflector exists outside the electronic device.

In a practical example, if the electronic device part detects without a reflector, when the optical signal is emitted from the emitting tube 05, since the optical signal cannot pass through the light receiving hole 08 by being reflected by the reflector, most of the generated optical signal will be scattered in the environment, and the probability of receiving the optical signal by the receiving tube 06 is very small. At this time, the optical signal received by the receiving tube is mainly obtained due to the original noise generated in the shell by the optical signal sent by the transmitting tube, and the voltage value output by the receiving component is the second voltage value.

In a practical example, if a detection mode is adopted in which there is a reflector outside the electronic device, when an optical signal is emitted from the emitting tube 05, the receiving tube 06 receives the optical signal because the optical signal passes through the light receiving hole 08 by reflection of the reflector, so that the optical signal received by the receiving tube includes the optical signal received by the light receiving hole and the original noise in the interior of the housing, and the voltage value output by the receiving tube is the third voltage value.

Since the original noise floor received by the receiving tube is much smaller than that received by the transmitting tube through the light receiving hole under the condition that the photosensor is normally assembled. Therefore, the third voltage value should be much larger than the second voltage value, and if the third voltage value is the same as the second voltage value or the difference between the third voltage value and the second voltage value is small, the corresponding receiving tube 06 is marked to be blocked, and cannot receive the optical signal reflected from the outside; if the difference between the third voltage value and the second voltage value is large, the corresponding receiving tube 06 is not shielded, and the optical signal reflected by the outside can be normally received.

Therefore, the present embodiment compares the difference between the third voltage value and the second voltage value with the magnitude of the second preset threshold; under the condition that the difference value is smaller than a second preset threshold value, the second voltage value is represented to be the same as or slightly changed from the third voltage value, and the light signal reflected from the outside cannot be received, so that the receiving tube 06 is determined to be shielded by the shell; under the condition that the difference value is larger than the second preset threshold value, the change of the second voltage value and the third voltage value is represented to be larger, and the receiving tube 06 can receive the externally reflected optical signal, so that the receiving tube 06 is determined not to be shielded by the shell.

In another possible embodiment, it is also possible to change the intensity of the optical signal of the transmitting tube 05 by applying different current intensities to the transmitting tube 05 under the condition that the reflector is arranged outside the electronic device, and detect whether the corresponding receiving tube 06 is shielded by the housing by detecting the voltage value change of the receiving tube 06 under two different optical signal intensities.

Under the condition that the receiving tube 06 is shielded by the shell, the corresponding receiving tube 06 is controlled to be in a closed state, so that the receiving tube 06 which cannot normally receive optical signals can be prevented from being powered, and the energy consumption of the photosensitive sensor 01 is reduced.

The present embodiment further provides an electronic device 11, referring to fig. 9, the electronic device 11 includes a housing 09 and a photosensitive sensor 01 disposed inside the housing, referring to fig. 2, the photosensitive sensor 01 includes an emitting component 02 and a receiving component 03, the photosensitive sensor 01 is disposed inside the housing of the electronic device, a light emitting hole 07 corresponding to the emitting component 02 and a light receiving hole 08 corresponding to the receiving component 03 are disposed on the housing, the emitting component 02 includes at least two emitting tube groups 04, and each emitting tube group 04 includes at least one emitting tube 05.
