Detailed Description
To further clarify the technical measures and effects taken by the present application to achieve the intended purpose of the invention, the following detailed description is given, along with the accompanying drawings and preferred embodiments, of specific embodiments, structures, features and effects according to the present application.
Referring to fig. 1, fig. 1 is a schematic view of a proximity sensor according to an embodiment of the present disclosure. The proximity sensor can be specifically an infrared proximity sensor, and can be arranged in a mobile terminal, wherein the mobile terminal comprises a mobile phone, a notebook computer, a tablet computer, a vehicle-mounted computer, an intelligent wearable device and other electronic devices which can be used in moving. The proximity sensor includes: a receiving end 10 and a transmitting end 20.
The transmitting terminal 20 includes a plurality of transmitting light sources 201, and a difference between a sum of transmitting powers of the transmitting light sources 201 and a rated transmitting power of the transmitting terminal 20 is smaller than a preset value. The emission light source 201 emits a signal, specifically an infrared signal.
The nominal emission power refers to the emission power of the emission end of the proximity sensor when the emission end has an emission light source. The value of the nominal transmission power is related to the model of the mobile terminal and factory settings.
The preset value is a small value, and can be set by self-definition, for example, 0.2, 0, etc., so as to ensure that the difference between the sum of the emission powers of the emission light sources 201 and the rated emission power of the emission end 20 is small. Preferably, the sum of the emission power of the emission light sources 201 is the same as the rated emission power of the emission end 20.
Alternatively, as shown in fig. 2, a plurality of emission light sources 201 of the emission end 20 are disposed around the receiving end 10. The number of the emission light sources 201 may specifically be an even number, such as 2 or 4 or more, or an odd number, such as 3 or 5 or more. As shown in fig. 2, the number of the emitting light sources 201 is 4, and 4 emitting light sources 201 may be arranged around the receiving end 10. Preferably, the distances between two adjacent emission light sources 201 are equal.
Further, when the number of the emission light sources 201 is 2, as shown in fig. 3, the 2 emission light sources 201 may be located at both lateral ends of the receiving end 10, or as shown in fig. 4, the 2 emission light sources 201 may be located at both longitudinal ends of the receiving end 10.
Optionally, the plurality of emitting light sources 201 are equidistant from the receiving end 10.
It is understood that, in practical applications, the plurality of emitting light sources 201 may not be limited to be arranged around the receiving end 10, and may be arranged around the receiving end 10 for multiple circles according to the number of the emitting light sources 201. The plurality of emission light sources 201 are uniformly surrounded around the receiving end 10. Alternatively, the distance between each circle of the emitting light source 201 and the receiving end 10 is increased or decreased from near to far in an equal ratio. Each emission light source 201 in the same circle of emission light sources 201 is equidistant from the receiving end 10.
In the embodiment of the application, through using a plurality of transmitting light sources to emit infrared signals simultaneously, the power of each transmitting light source can be set to be a lower value, and simultaneously, the power is not influenced because the energy of the receiving end is the sum of the infrared energy emitted by the plurality of transmitting light sources, so that the problem of screen flashing can be solved, and the detection distance can be ensured.
Fig. 5 is a schematic implementation flow chart of a proximity sensor control method according to an embodiment of the present disclosure. The proximity sensor setting method may be applied to a mobile terminal equipped with the proximity sensor shown in fig. 1 described above, the transmitting end of which includes a plurality of transmitting light sources. As shown in fig. 5, the proximity sensor control method includes:
s101, obtaining rated transmitting power of a transmitting end;
the nominal emission power refers to the emission power of the emission end of the proximity sensor under the condition that the emission end is provided with one emission light source. The rated emission power varies with the light environment outside the handset.
S102, determining an emission light source to be driven and the emission power of the emission light source to be driven according to a preset driving rule and a rated emission power;
the emission light sources to be driven may be all emission light sources or may be part of emission light sources according to a preset driving rule. That is, all the emission light sources may be driven to emit infrared signals at a time, or a part of the emission light sources may be driven to emit infrared signals first, and then the driven emission light sources may be dynamically increased or decreased according to the state of the splash screen.
The difference between the sum of the emission power of the emission light sources to be driven and the rated emission power of the emission end is smaller than a preset value. Alternatively, the power value obtained by dividing the rated emission power by the number of the emission light sources to be driven may be used as the value of the emission power of each emission light source to be driven.
And S103, driving each emission light source to be driven, and emitting an infrared signal according to the determined emission power.
In the embodiment of the application, through using a plurality of transmitting light sources to emit infrared signals simultaneously, the power of each transmitting light source can be set to be a lower value, and simultaneously, the power is not influenced because the energy of the receiving end is the sum of the infrared energy emitted by the plurality of transmitting light sources, so that the problem of screen flashing can be solved, and the detection distance can be ensured.
Fig. 6 is a schematic implementation flow chart of a proximity sensor control method according to another embodiment of the present application. The proximity sensor setting method may be applied to a mobile terminal equipped with the proximity sensor shown in fig. 1 described above, the transmitting end of which includes a plurality of transmitting light sources. In the embodiment, the predetermined driving rule is to drive the part emitting light source for the first time. Unlike the embodiment shown in fig. 5, as shown in fig. 6, after step S103, the method further includes the following steps:
s201, if the screen flashing happens at present, determining the transmitting power of each transmitting light source according to the total number of the transmitting light sources and the rated transmitting power;
specifically, whether screen flashing happens currently is judged, and if screen flashing happens currently, the emitting power of each emitting light source is appropriate and does not need to be adjusted. If the current screen flashing happens, which indicates that the transmitting power of a single transmitting light source is too high and needs to be adjusted, the transmitting power of each transmitting light source is determined according to the total number of the transmitting light sources and the rated transmitting power. The difference between the sum of the emission power of all the emission light sources and the rated emission power of the emission end is smaller than a preset value. Optionally, a power value obtained by dividing the rated emission power by the total number of the emission light sources is used as a new emission power value of each emission light source.
Optionally, a shortcut button, an icon, or a menu for reporting that a screen splash occurs may be preset, and when a click or press event of the shortcut button, the icon, or the menu is monitored, the screen splash is determined to occur. Or when the third-party light sensor detects that the frequency of light flicker above the display screen is greater than the preset frequency, determining that the screen flicker occurs.
S202, driving the non-working emission light source, emitting an infrared signal according to the determined emission power, and reducing the emission power of the working emission light source to the determined emission power.
Optionally, the emission power of the emission light sources to be driven in the batch is determined according to the number of the emission light sources to be driven in the batch, the number of the emission light sources to be operated and the rated emission power, the emission light sources to be driven in the batch are driven to emit infrared signals according to the determined emission power, and meanwhile, the emission power of the emission light sources to be operated is reduced to the determined emission power. And then judging whether the screen flash occurs again, if so, repeatedly executing the steps of determining the emission power of the batch of emission light sources which need to be driven and do not work according to the number of the emission light sources which need to be driven and do not work, the number of the emission light sources which need to be driven and the rated emission power, driving the batch of emission light sources which need to be driven and do not work to emit infrared signals according to the determined emission power, and simultaneously reducing the emission power of the emission light sources which do work to the determined emission power until the preset time length is exceeded and the screen flash does not occur.
The emission power of the batch of emission light sources to be driven, which are not in operation, may be a power value obtained by dividing the rated emission power by the sum of the number of emission light sources to be driven, which are not in operation, and the number of emission light sources in operation.
In particular, in practical applications, the number of non-operating light emitting sources to be driven may or may not be the same for each batch. When a plurality of emission light sources are arranged around the receiving end of the proximity sensor, the emission light sources which do not work can be driven circle by circle according to the number of circles around.
In the embodiment of the application, through using a plurality of transmitting light sources to emit infrared signals simultaneously, the power of each transmitting light source can be set to be a lower value, and simultaneously, the power is not influenced because the energy of the receiving end is the sum of the infrared energy emitted by the plurality of transmitting light sources, so that the problem of screen flashing can be solved, and the detection distance can be ensured. Furthermore, the number of the working emitting light sources is dynamically increased by driving the emitting light sources for the first time and then according to whether the screen flashing occurs, so that the infrared signals emitted by the emitting light sources are gathered around the receiving end to the maximum extent, the receiving end can receive enough infrared energy, and the working stability of the receiving end is ensured.
Fig. 7 is a schematic implementation flow chart of a proximity sensor control method according to another embodiment of the present application. The proximity sensor setting method may be applied to a mobile terminal equipped with the proximity sensor shown in fig. 1 described above, the transmitting end of which includes a plurality of transmitting light sources. A plurality of emitting light sources are disposed around the receiving end of the proximity sensor. In this embodiment, the predetermined driving rule is to drive all the light emitting sources for the first time. Unlike the embodiment shown in fig. 5, as shown in fig. 7, after step S103, the following steps are further included:
s301, if the screen flashing does not occur within the preset time, closing the working transmitting light sources according to the sequence from far to near from the receiving end, and adjusting the transmitting power of the rest of the non-closed working transmitting light sources according to the rated transmitting power;
s302, if the screen flashing happens, the emitting light source which is turned off last time before the screen flashing happens is re-driven, the infrared light signal is emitted according to the emitting power before the turning-off, and the emitting power of the non-re-driven emitting light source which is working is adjusted according to the rated emitting power.
Optionally, a shortcut button, an icon, or a menu for reporting that a screen splash occurs may be preset, and when a click or press event of the shortcut button, the icon, or the menu is monitored, the screen splash is determined to occur. Or when the third-party light sensor detects that the frequency of light flicker above the display screen is greater than the preset frequency, determining that the screen flicker occurs.
If the screen flashing does not occur within the preset time length, the working emission light sources are turned off in batches according to the sequence from far to near from the receiving end, and the emission power of the remaining non-turned-off working emission light sources is adjusted according to the rated emission power, so that the difference between the sum of the emission power of the working emission light sources and the rated emission power of the emitting end is smaller than a preset value.
It will be appreciated that as the number of active light emitting sources is reduced, the emission power of the individual light emitting sources increases and, correspondingly, the chance of a flicker occurring increases. Therefore, after each batch of working emission light sources are turned off, whether screen flashing occurs is judged, if the screen flashing occurs, and the power of a single emission light source is over high, the emission light source which is turned off last time before the screen flashing occurs is re-driven, an infrared light signal is emitted according to the emission power before turning off, and the emission power of the non-re-driven working emission light source is adjusted according to the rated emission power, so that the difference between the sum of the emission power of the working emission light sources and the rated emission power of an emission end is smaller than a preset value. If the screen flash does not occur, further closing the next batch of emission light sources, and repeating the steps until the emission light source closed last time before the screen flash occurs is re-driven when the screen flash occurs, emitting the infrared light signal according to the emission power before closing, and adjusting the emission power of the non-re-driven emission light source which is working according to the rated emission power.
In the embodiment of the application, through using a plurality of transmitting light sources to emit infrared signals simultaneously, the power of each transmitting light source can be set to be a lower value, and simultaneously, the power is not influenced because the energy of the receiving end is the sum of the infrared energy emitted by the plurality of transmitting light sources, so that the problem of screen flashing can be solved, and the detection distance can be ensured. Furthermore, all the emitting light sources are driven for the first time, and then the number of the emitting light sources in work is dynamically reduced according to whether screen flashing occurs or not, so that infrared signals emitted by the emitting light sources are gathered around the receiving end to the maximum extent, the receiving end can be ensured to receive enough infrared energy, and the working stability of the receiving end is ensured.
