It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without inventive step, are within the scope of the present application.
Referring to fig. 1, fig. 1 is a schematic view of a first structure of an electronic device according to an embodiment of the present disclosure. The electronic device 10 may include a housing 11, a display 12, a circuit board 13, a battery 14, and a detector 15. It should be noted that the electronic device 10 is not limited thereto, for example, the electronic device 10 may further include a camera, a receiver, bluetooth, etc.
Wherein the housing 11 may form an outer contour of the electronic device 10. In some embodiments, the housing 11 may be a metal housing, such as a metal such as magnesium alloy, stainless steel, and the like. It should be noted that the material of the housing 11 in the embodiment of the present application is not limited to this, and other manners may also be adopted, such as: the housing 11 may be a plastic housing, a ceramic housing, a glass housing, etc. Display screen 12 may include, among other things, a touch sensor array (i.e., display screen 10 may be a touch display screen).
Wherein the display screen 12 is mounted in the housing 11. The display screen 12 is electrically connected to the circuit board 13 to form a display surface of the electronic device 10. In some embodiments, the display surface of the electronic device 10 may be provided with non-display areas, such as: the top end or/and the bottom end of the electronic device 10 may form a non-display area, that is, the electronic device 10 forms a non-display area on the upper portion or/and the lower portion of the display 12, and the electronic device 10 may mount a camera, a receiver, and the like on the non-display area. Note that the display surface of the electronic device 10 may not be provided with the non-display area, that is, the display 12 may be a full-screen. The display screen may be laid over the entire display surface of the electronic device 10, so that the display screen can be displayed in a full screen on the display surface of the electronic device 10.
It should be noted that, in the description of the present application, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; may be mechanically connected, may be electrically connected or may be in communication with each other; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.
The display 12 may be in a regular shape, such as a rectangular parallelepiped structure or a rounded rectangular structure, and the display 12 may also be in an irregular shape.
The display 12 may be one or a combination of liquid crystal display, organic light emitting diode display, electronic ink display, plasma display, and display using other display technologies. The display screen 12 may include an array of touch sensors (i.e., the display screen 12 may be a touch display screen). The touch sensor may be a capacitive touch sensor formed from an array of transparent touch sensor electrodes (e.g., Indium Tin Oxide (ITO) electrodes), or may be a touch sensor formed using other touch technologies, such as sonic touch, pressure sensitive touch, resistive touch, optical touch, and the like, in embodiments of the present application, a capacitive touch sensor formed from an array of transparent touch sensor electrodes (e.g., Indium Tin Oxide (ITO) electrodes).
It should be noted that, in some embodiments, a cover plate may be disposed on the display 12, and the cover plate may cover the display 12 to protect the display 12. The cover may be a clear glass cover so that the display 12 is shown through the cover. In some embodiments, the cover plate may be a glass cover plate made of a material such as sapphire.
In some embodiments, after the display 12 is mounted on the housing 11, a receiving space is formed between the housing 11 and the display 12, and the receiving space can receive components of the electronic device 10, such as the circuit board 13, the battery 14, and the like.
The display 12 may be a capacitive touch screen, which may be formed by attaching a layer of transparent special metal conductive material on a glass surface. Since a human body is a good conductor, when a finger or other organism approaches or touches the metal layer, the capacitance of the touch point on the capacitive touch panel changes, and whether an organism approaches or touches the display screen can be determined through the change of the capacitance.
When the environmental temperature changes, the temperature of the electronic device in the electronic device 10 changes, so that the characteristics of the electronic device also change, the capacitance of the display screen 12 also changes, and when the temperature decreases, the capacitance of the display screen 12 increases; at high temperatures, the capacitance of the display 12 may decrease. Therefore, the capacitance values corresponding to the display 12 are different at different temperatures.
The circuit board 13 is mounted in the housing 11, the circuit board 13 may be a main board of the electronic device 10, and one or more functional devices such as a motor, a microphone, a speaker, an earphone interface, a universal serial bus interface, a camera, a distance sensor, an ambient light sensor, a receiver, and a processor may be integrated on the circuit board 13. It is noted that, in the description of the present application, "a plurality" means two or more unless specifically defined otherwise.
In some embodiments, the circuit board 13 may be fixed within the housing 11. Specifically, the circuit board 13 may be screwed to the housing 11 by screws, or may be snap-fitted to the housing 11. It should be noted that the way of fixing the circuit board 13 to the housing 11 is not limited to this, and other ways, such as a way of fixing by a snap and a screw, may also be used.
Wherein a battery 14 is mounted in the housing 11, and the battery 11 is electrically connected to the circuit board 13 to supply power to the electronic device 10. The housing 11 may serve as a battery cover for the battery 14. The case 11 covers the battery 14 to protect the battery 14, reducing damage to the battery 14 due to collision, dropping, and the like of the electronic apparatus 10.
Wherein the detector 15 may detect the temperature of the display screen 12 and the detector 15 may comprise a temperature detector.
In some embodiments, as shown in FIG. 2, the detector 15 may be disposed on a non-display surface 121 of the display screen 12. It will be appreciated that the non-display side 121 of the display 12 is located within the electronic device 10, and that the non-display side 121 of the display 12 is disposed opposite the display side 122 of the display 12. As shown in fig. 3, the detector 15 is not visible when viewed from outside the electronic device 10.
In some embodiments, the detector 15 is remote from the control chip 16 of the display screen 12. Because the control chip 16 of the display screen 12 is used for controlling the display or/and touch of the display screen 12, the temperature of the control chip 16 of the display screen 12 is higher than the temperature of other areas of the display screen 12, and the detector 15 is arranged far away from the control chip 16 of the display screen 12, so that the accuracy of detecting the temperature of the display screen 12 can be improved.
It should be noted that the detector 15 may be disposed inside the display 12. When the detector 15 is disposed inside the display 12, it is also remote from the control chip 16.
In some embodiments, as shown in fig. 4, the electronic device 10 may further include a base 17, and the base 17 may include a universal Serial interface socket, such as a usb (universal Serial bus) interface socket. It should be noted that the base 17 is not limited to this, for example, the base 17 may further include an earphone socket. Wherein the base 17 abuts the display screen 12.
The detector 15 may be disposed on the base 17 with the detector 15 positioned between the base 17 and the display screen 12. Since it is not easy to directly measure the temperature of the display 12 when actually detecting the temperature of the display 12, the temperature of the base 17 adjacent to the display 12 can be detected by the detector 15 to determine the temperature of the display 12. Since the display 12 is adjacent to the base 17, the temperature of the display 12 is transmitted to the base 17, and the temperature of the display 12 has a small error from the temperature of the base 17. Therefore, the temperature of the base 17 can be taken as the temperature of the display 12.

Wherein the storage and processing circuit 131 may be integrated on the circuit board 13.

Referring to fig. 7, fig. 7 is a third block diagram of an electronic device according to an embodiment of the present disclosure, in which a processor 18 of the electronic device 10 is respectively coupled to a memory 19, a display 12, and a detector 15.
The detector 15 may detect the current temperature of the display screen 12 and may transmit the detected current temperature to the processor 18. The processor 18 may also obtain the current temperature of the display screen 12 from the detector 15.
In some embodiments, the sensor 1321 may detect motion data of the electronic device 10, may transmit the detected motion data to the processor 18, and the processor 18 may derive a motion direction and a motion distance of the electronic device 10 from the motion data. The sensor 1321 may be an acceleration sensor. The processor 18 may also acquire motion data from the sensor 1321 to determine the direction and distance of motion of the electronic device 10.
The control chip 16 in the display screen 12 may be used to detect the capacitance value of the display screen 12 at the current temperature, and may transmit the detected capacitance value to the processor 18. The processor 18 may also obtain the capacitance value of the display screen 12 at the current temperature from the control chip 16 of the display screen 12.
The memory 19 may store a preset sample set, wherein the preset sample set includes a first standard capacitance value at a preset standard temperature and a second standard capacitance value at a current temperature.
In which, when the display screen 12 is in a non-proximity state, standard capacitance values at various temperatures between a low temperature limit for using the electronic device and a high temperature limit for using the electronic device, for example, -15 degrees celsius to 55 degrees celsius, can be tested in advance, and a preset sample set can be established and stored in the memory 19. In a preset sample set, each temperature respectively corresponds to a standard capacitance value in the preset sample set; and one of the temperatures is set to a standard temperature (normal temperature), for example, 25 degrees celsius is set to the standard temperature.
It should be noted that the terms "first" and "second" in the description of the present application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features.
When the display screen 12 is in the proximity state, the capacitance of the display screen 12 is mainly affected by the human body and the temperature, and since the ambient temperature of the electronic device 10 is easy to change, the capacitance of the display screen 12 is unstable, so that whether the display screen 12 is in the proximity state or not can not be normally determined. Therefore, before determining whether the display panel 12 is in the proximity state, the variation of the capacitance of the display panel 12 caused by the temperature needs to be eliminated, so as to eliminate the influence of the temperature on the capacitance of the display panel 12.
In the embodiment of the present application, the processor 18 may obtain the current temperature of the display screen 12 detected by the detector 15 and the capacitance value of the display screen 12 at the current temperature detected by the control chip of the display screen 12, and then the processor 18 extracts a first standard capacitance value of the display screen 12 at the standard temperature and a second standard capacitance value of the display screen 12 at the current temperature from the preset sample set of the memory 19. The processor 18 then calculates a first difference between the first capacitance and the second capacitance, and the processor 18 can determine the state of the display 12 based on the difference and the capacitance of the display 12 at the current temperature.
Wherein the processor 18 may calculate a second difference between the first difference and the capacitance value of the display screen 12 at the current temperature, and the processor 18 then compares the second difference to a preset threshold. Since the capacitance increases when the display 12 is close to the human body; when the human body is far away, the capacitance value is reduced. Therefore, when the second difference is greater than or equal to the preset threshold, it may be determined that the display screen 12 is in the proximity state; when the second difference is less than the preset threshold, it may be determined that the display screen 12 is in a non-proximity state. The preset threshold value may be set according to actual conditions, such as 600 farads.
Wherein it may be detected whether the electronic device 10 triggers a preset event before the processor 18 obtains the current temperature of the display screen 12. When a preset event is triggered, the processor 18 acquires the motion data of the electronic device detected by the sensor 1321, the processor 18 can obtain the motion direction and the motion distance of the electronic device according to the motion data, and when the motion direction and the motion distance simultaneously meet a preset condition, the current temperature of the display screen 12 is detected. Wherein, the preset event is set by a user, such as a call state; the preset conditions can be set according to actual conditions, for example, the moving direction is upward, and the moving distance is 3 cm.
When the display 12 is in the proximity state, the processor 18 may control the display 12 to turn off or lock the display.
To further explain the status determining process of the display screen in the embodiment of the present application, the following description is made in terms of a status determining method of the display screen, which can be applied to the electronic device. The electronic device may refer to the electronic device described above, wherein the display screen may refer to the display screen described above. As shown in fig. 8, the specific process may be as follows:
101. and acquiring the current temperature of the display screen.
In practical applications, before acquiring the current temperature of the display screen, whether a preset event is triggered or not may be detected, so as to reduce consumption of resources. The preset event can be set by default by the electronic device or set by the user according to the actual situation. In the embodiment of the application, the preset event is defaulted to a call state, and when the electronic equipment is in the call state, the current temperature of the display screen is acquired. The method can directly call a telephone application program of the electronic equipment or other application programs with voice call functions to detect whether the electronic equipment is in a call state. The call state may include a dialing state, an incoming call state and a connection state.
Since during the use of the electronic device, when a preset event trigger is received, the user generally moves the electronic device to the face position and then brings the display screen close to the face. Therefore, when the preset event trigger is detected, the motion condition of the electronic equipment can be detected, and whether the step of acquiring the current temperature of the display screen is performed or not is determined according to the motion condition of the electronic equipment. The motion condition may include a motion direction and a motion distance. That is, before the step "acquiring the current temperature of the display screen", the method may further include:
when the trigger of a preset event is detected, detecting the movement direction and the movement distance of the electronic equipment;
and determining whether to execute the step of acquiring the current temperature of the display screen according to the movement direction and the movement distance.
Specifically, the acceleration sensor can be arranged on the shell of the electronic device, and when the detection function of the acceleration sensor is started, the movement direction and the distance of the electronic device can be detected. The detection function may also be automatically enabled when a predetermined event is triggered. Whether the electronic equipment moves and the moving direction of the electronic equipment can be obtained through the electronic equipment motion data acquired by the acceleration sensor. And then the moving distance of the whole moving process is obtained by integrating the moving time. For example, if it is determined that the electronic device has an upward movement while being triggered by the preset event, and the final effective distance of movement within the preset time is greater than or equal to the preset upward movement distance, for example, the effective distance of movement within 10 seconds is greater than or equal to 3CM, it is determined to perform the step of acquiring the current temperature of the display screen, otherwise, it is not performed. That is, the step of determining whether to perform the step of acquiring the current temperature of the display screen according to the moving direction and the moving distance may include:
judging whether the movement direction and the movement distance meet preset conditions or not;
and if so, executing the step of acquiring the current temperature of the display screen.
Specifically, the movement direction and the movement distance of the electronic device within the preset time may be obtained, and when the movement direction and the movement distance simultaneously satisfy a preset condition, that is, the movement direction of the electronic device is upward and the movement distance is greater than a preset distance, the step of obtaining the current temperature of the display screen is determined to be performed.
The moving direction is generally defaulted to moving upwards, and can also be set according to the actual situation, and the preset distance and the preset time can be set by default for the electronic equipment and can also be set by the user according to the actual situation.
102. And acquiring the capacitance value of the display screen at the current temperature.
Specifically, the capacitance value of the display screen at the current temperature can be acquired through a display screen control chip in the electronic device.
103. And acquiring the capacity value variation of the display screen from the preset standard temperature to the current temperature, wherein the capacity value variation is the capacitance value variation caused by the temperature.
Specifically, when the display screen is in a non-proximity state, the standard capacitance values at various temperatures between the extreme low temperature of the electronic device and the extreme high temperature of the electronic device can be tested in advance to establish a preset sample set, and each temperature corresponds to one standard capacitance value in the preset sample set respectively; and one of the temperatures is set to a standard temperature (normal temperature), for example, 25 degrees celsius is set to the standard temperature. The standard capacitance value is the capacitance value of the display screen under the condition of being only influenced by temperature.
Therefore, the standard capacitance value corresponding to the display screen at the current temperature and the standard capacitance value corresponding to the display screen at the standard temperature can be extracted from the preset sample set, and the capacitance value variation caused by the temperature can be obtained according to the two standard capacitance values. That is, the step of "obtaining the capacity value variation of the display screen from the preset standard temperature to the current temperature" may include:
extracting a first standard capacitance value of the display screen at a preset standard temperature from a preset sample set;
extracting a second standard capacitance value of the display screen at the current temperature from a preset sample set;
and acquiring the capacitance value variation according to the first standard capacitance value and the second standard capacitance value.
Specifically, the difference between the first standard capacitance value and the second standard capacitance value can be obtained through calculation, and the difference is the capacitance variation.
104. And judging whether the display screen is in a close state or not based on the capacitance value and the capacitance value variation.
When the display screen is in the state of being close, the capacitance value of display screen receives the influence of human body and temperature mainly, because the ambient temperature who uses electronic equipment easily changes, can lead to the capacitance value of display screen unstable for can't normally judge whether the display screen is in the state of being close. Therefore, before determining whether the display screen is in the proximity state, the variation of the capacitance value of the display screen caused by the temperature needs to be eliminated, and the influence of the temperature on the capacitance value of the display screen is eliminated.
Specifically, the difference between the capacitance value and the capacitance value variation at the current temperature can be obtained through calculation, and whether the display screen is in the approaching state or not is judged according to the difference. That is, the step of "determining whether the display screen is in the close state based on the capacitance value and the capacitance value variation" may include:
acquiring a difference value between the capacitance value and the capacitance value variation;
and judging whether the display screen is in a close state or not according to the difference value.
The difference value can be compared with a preset threshold value, and whether the display screen is in a close state or not is determined according to the comparison result. When the display screen is close to a human body, the capacitance value can be increased; when the human body is far away, the capacitance value is reduced. Therefore, if the difference is greater than or equal to the preset threshold, it may be determined that the display screen is in a close state; if the difference is less than the preset threshold, it may be determined that the display screen is in a non-proximity state. That is, the step of "judging whether the display screen is in the proximity state according to the difference" may include:
if the difference value is not smaller than a preset threshold value, the display screen is in a close state;
and if the difference value is smaller than the preset threshold value, the display screen is in a non-close state.
The preset threshold is a default threshold set by a designer for the electronic device when the electronic device leaves a factory.
According to the display screen state judging method provided by the embodiment, the capacity value variable quantity caused by the temperature can be eliminated when the state of the display screen is judged, the influence of external factors on the display screen can be reduced, the misoperation of the display screen is reduced, and the accuracy of judging the state of the display screen is improved.
According to the description of the above embodiment, the state determination method of the display screen of the present application will be further explained below.
Referring to fig. 9, fig. 9 is another schematic flow chart of the method for determining a status of a display screen according to the embodiment of the present application, and the specific flow may be as follows:
201. when the electronic equipment is detected to be in a call state, the movement direction and the movement distance of the electronic equipment are detected.
Specifically, a phone application of the electronic device or another application having a voice call function may be directly invoked to detect whether the electronic device is in a call state, where the call state may include a dialing state, an incoming call state, and a connection state.
During the use of the electronic device, when the electronic device is in a call state, the user generally moves the electronic device to the face position and then brings the display screen close to the face. Therefore, when the electronic equipment is in a call state, the motion condition of the electronic equipment can be detected, and whether the electronic equipment has a tendency of approaching the human face or not can be judged according to the motion condition.
Specifically, an acceleration sensor may be disposed on a housing of the electronic device, and when a detection function of the acceleration sensor is turned on, a movement direction and a movement distance of the electronic device may be detected. The detection function may also be automatically enabled when a predetermined event is triggered. Whether the electronic equipment moves and the moving direction of the electronic equipment can be obtained through the electronic equipment motion data acquired by the acceleration sensor. And then the moving distance of the whole moving process is obtained by integrating the moving time.
202. And judging whether the movement direction and the movement distance meet preset conditions, if so, executing a step 203, and if not, ending the process.
Specifically, the moving direction and the moving distance of the electronic device within the preset time may be obtained, and when the moving direction and the moving distance simultaneously satisfy the preset condition, that is, the moving direction of the electronic device is upward, and the moving distance is greater than or equal to the preset distance, it is determined to execute step 203.
For example, if it is determined that the electronic device has moved upward while the electronic device is in the call state, and the final effective distance moved within the preset time is equal to or greater than the preset distance moved upward, it is determined to perform step 203, otherwise, it is not performed. For example, the effective distance for 10 seconds of movement is 3CM or more upward.
The moving direction is generally defaulted to moving upwards, and can also be set according to the actual situation, and the preset distance and the preset time can be set by default for the electronic equipment and can also be set by the user according to the actual situation.
203. And acquiring the current temperature of the display screen.
Wherein, the current temperature of the display screen can be detected by the temperature sensor, and the temperature sensor can transmit the detected current temperature to the processor of the electronic device. Reference is made in particular to the above.
204. And acquiring the capacitance value of the display screen at the current temperature.
Specifically, the capacitance value of the display screen at the current temperature can be acquired through a display screen control chip in the electronic device.
When the environmental temperature changes, the temperature of an electronic device in the electronic equipment changes, so that the characteristics of the electronic device also change, the capacitance value of the display screen also changes, and the capacitance value of the display screen increases when the temperature decreases; at high temperatures, the capacitance of the display screen decreases. Therefore, the capacitance values corresponding to the display screen are different at different temperatures.
205. And acquiring the capacity value variation of the display screen from the preset standard temperature to the current temperature, wherein the capacity value variation is the capacitance value variation caused by the temperature.
Specifically, a standard capacitance value corresponding to the display screen at the current temperature and a standard capacitance value corresponding to the display screen at the standard temperature may be extracted from the preset sample set, and then, a capacitance value variation caused by the temperature may be obtained according to the two standard capacitance values.
206. And acquiring a difference value between the capacitance value and the capacitance value variation.
Specifically, the difference between the capacitance value and the capacitance value variation at the current temperature can be obtained through calculation, and whether the display screen is in the approaching state or not is judged according to the difference.
207. And judging whether the display screen is in a close state or not according to the difference value.
The difference value can be compared with a preset threshold value, and whether the display screen is in a close state or not is determined according to the comparison result. When the display screen is close to a human body, the capacitance value can be increased; when the human body is far away, the capacitance value is reduced. Therefore, if the difference is greater than or equal to the preset threshold, it may be determined that the display screen is in a close state; if the difference is less than the preset threshold, it may be determined that the display screen is in a non-proximity state. The preset threshold is a default threshold set by a designer for the electronic device when the electronic device leaves a factory.
According to the display screen state judging method provided by the embodiment, the capacity value variable quantity caused by the temperature can be eliminated when the state of the display screen is judged, the influence of external factors on the display screen can be reduced, the misoperation of the display screen is reduced, and the accuracy of judging the state of the display screen is improved.
