Description

Technical Field

[0001] This invention relates to the field of smart terminals, and more particularly to a method, apparatus, electronic device, and readable medium for identifying water ingress into a screen. Background Technology

[0002] Currently, waterproofing of smart terminals is mainly achieved through overall waterproofing. This involves adding waterproof silicone rings to the gaps in the device to increase the waterproof rating, preventing water from entering the terminal and avoiding short circuits in the motherboard components that could damage the device. However, this method increases the difficulty of overall design and assembly, and also significantly increases the overall cost.

[0003] Meanwhile, although some smart terminals increase their waterproof rating by adding waterproof silicone rings to gaps, these rings can sometimes shift or fall off during use, such as when the terminal is bent. In this case, water can easily seep into the terminal and cause short circuits in the components on the motherboard.

[0004] On the other hand, some smart devices are waterproofed by checking for short circuits between the two different metal pins of the USB port. If a short circuit occurs, it indicates that water has entered the USB port, and the USB circuit is physically disconnected, thus protecting the USB port from being burned out due to the short circuit. However, some smart devices do not use USB for charging, or even if they do use a USB port, they will protect the USB port well on the casing, but this increases the design complexity.

[0005] Therefore, how to promptly identify the risk of water damage to the screen without increasing design complexity and to provide timely warnings about this risk is an urgent problem to be solved. Summary of the Invention

[0006] To at least solve the above-mentioned technical problems, embodiments of the present invention provide a method for identifying the risk of water ingress, which identifies whether water covers the surface of the display screen by measuring the magnitude of the signal received by the sensor receiver.

[0007] To achieve the above objectives, an embodiment of the present invention provides a method for identifying water ingress into a screen, comprising:

[0008] Detect proximity data obtained from proximity sensors;

[0009] When the data is close to or less than or equal to the preset alarm threshold, a water ingress risk warning will be displayed on the screen.

[0010] To achieve the above objectives, embodiments of the present invention also provide a device for identifying water ingress into a screen, comprising:

[0011] The detection unit is used to detect proximity data obtained by the proximity sensor.

[0012] The alarm unit is used to output a water ingress risk warning on the screen when the approach data is less than or equal to a preset alarm threshold.

[0013] To achieve the above objectives, embodiments of the present invention also provide an electronic device, including the steps of performing the above-described method for identifying water ingress into the screen.

[0014] To achieve the above objectives, embodiments of the present invention also provide a computer-readable storage medium storing one or more programs, which, when executed, perform the steps of the above-described method for identifying water ingress into a screen.

[0015] This invention utilizes an infrared proximity sensor to identify objects covering the cover surface. Based on the signal strength received by the sensor receiver, it identifies water covering the display screen glass cover surface, determines the risk of water ingress into the smart terminal, and reminds the user to keep the smart terminal away from water through vibration, and / or sound, and / or flashing indicator lights, and / or displaying reminder text on the screen. It records the time and duration of water ingress and can also remind the user to wipe the water off the screen surface, improving the user experience in touchscreen operation or fingerprint recognition.

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] An embodiment of the present invention provides a method for identifying water ingress into a screen, comprising:

[0024] Detect proximity data obtained from proximity sensors;

[0025] When the data is close to or less than or equal to the preset alarm threshold, a water ingress risk warning will be displayed on the screen.

[0026] Example 1

[0027] Figure 1 This is a schematic diagram illustrating the working principle of a proximity sensor in a smart terminal. Figure 2 This is an example of a proximity sensor operating when there are no obstacles on the surface of a smart terminal. Figure 3 This is an example of a proximity sensor operating when there is water on the surface of a smart terminal, which will be referred to below. Figure 1-3 The method for identifying water ingress risk according to embodiments of the present invention will be described in detail.

[0028] In embodiments of the present invention, such as Figure 1 As shown, the proximity sensor emits a signal, which is reflected by the TP (Touch Panel) glass cover and enters the proximity sensor's receiver. The receiver uses the value to identify whether an object is near the screen.

[0029] In one embodiment of the present invention, the proximity sensor is an infrared sensor.

[0030] In embodiments of the present invention, such as Figure 2 As shown, the principle of light reflection on the glass cover 101 of the TP (Touch Panel) by the proximity sensor is as follows:

[0031] The refractive index n(glass) is 1.53, and the refractive index n(air) is 1.

[0032] Principle of light refraction: n(glass) * sina = n(air) * sinb;

[0033] The angle at which total internal reflection occurs inside the glass is (at which point angle b is 90 degrees);

[0034] a = arcsin(1*sin90 / 1.53) = 40 degrees.

[0035] Therefore, it can be concluded that the angle of light refraction is 40 degrees when there are no obstacles on the surface of the TP (Touch Panel) glass cover (in the state of only air).

[0036] That is, in this embodiment of the invention, when there are no obstacles on the surface of the TP (Touch Panel) glass cover (only air), the proximity sensor transmitter 11 emits an infrared signal, and the infrared signal is reflected back to the proximity sensor receiver 12 by the TP (Touch Panel) glass cover at an angle of 40 degrees.

[0037] In embodiments of the present invention, such as Figure 3 As shown, the principle of light reflection on the glass cover 101 of the TP (Touch Panel) by the proximity sensor is as follows:

[0038] The refractive index of water, n(water), is 1.33;

[0039] Principle of light refraction: n(glass) * sina = n(water) * sinc;

[0040] The angle at which light undergoes total internal reflection inside the glass is (at which point angle c is 90 degrees);

[0041] a = arcsin(1.33*sin90 / 1.53) = 59 degrees.

[0042] That is, in this embodiment of the invention, when there is water on the TP glass cover, the total internal reflection angle of the TP glass cover surface increases from 40 degrees to 59 degrees. This means that when there was no water on the glass cover, light with an angle greater than 40 degrees was reflected back to the receiving end, while light with an angle less than 40 degrees shone into the air. After there is water on the glass cover, light with an angle greater than 59 degrees is reflected back to the receiving end, while light with an angle less than 59 degrees shone into the water and then into the air. In this way, if there is water on the TP glass cover, the amount of signal received by the proximity sensor receiving end will decrease.

[0043] In one embodiment, the proximity sensor utilizes an infrared transmitting and receiving device. The transmitting device emits infrared light, and when an object is located a certain distance above the sensor, the object reflects the infrared light, which then enters the receiving device. When there are water droplets on the glass cover, more of the infrared light emitted by the transmitting device will pass through the water into the air, and less infrared light will be reflected back into the receiving device.

[0044] exist Figure 1In this diagram, 11 is an infrared transmitter, and 12 is an infrared receiver. The infrared receiver receives the infrared light emitted by the transmitter and then reflected back. The receiver acts as an infrared sensor, converting the intensity of the received infrared light into voltage or current, which characterizes the intensity. This voltage or current is then represented by a digital value, indicating the magnitude of the infrared intensity. The threshold value (i.e., the alarm threshold) for the intensity of the infrared light received by the receiver can be set through this digital value setting.

[0045] In one embodiment, two alarm thresholds are set in the infrared receiving device. If the threshold is less than or equal to the first threshold, water is present on the surface of the glass cover. If the threshold is less than the first threshold and less than the second threshold, no water immersion alarm is issued (i.e., there is no water on the screen surface, so no water immersion warning is issued). That is, the water immersion warning is only issued within the range formed by the first threshold and the second threshold.

[0046] In one embodiment, when there is water on the surface of the TP glass cover, if the signal received by the proximity sensor receiver is less than or equal to a preset alarm threshold, it is considered that there is water on the surface of the TP glass cover, and a water immersion warning is issued to the user's startup screen and / or terminal.

[0047] In one embodiment, the alarm when there is water on the surface of the TP glass cover includes: immediately executing an alarm action, or recording and monitoring risk warnings, and when the number of times the risk warning for water ingress on the screen is detected exceeds a threshold within a preset period, then issuing a warning about the risk of water ingress on the screen or executing a shutdown action.

[0048] In one embodiment, the alarm channels for when there is water on the surface of the TP glass cover include: risk warnings via a screen, and / or a speaker, and / or a light, and / or a vibration device.

[0049] In one embodiment, the alarm for water on the TP glass cover surface includes alarms such as vibration, sound, flashing indicator lights, and / or displaying reminder text on the screen.

[0050] In one embodiment, the alarm is terminated when the signal received by the proximity sensor receiver exceeds a preset alarm threshold; or, the alarm is restored without prompting the user's startup screen and / or terminal with a water immersion warning.

[0051] In one implementation, a proximity sensor continuously collects signals. If the signal indicates the presence of water, the time of alarm activation and the duration of the alarm are recorded. A longer alarm duration indicates a greater risk of water ingress. Simultaneously, the smart terminal can also upload this data to a cloud server for storage, allowing the time of water ingress and its duration to be recorded in the vicinity of the smart terminal.

[0052] When water is detected during fingerprint recognition or other operations, if the fingerprint cannot be recognized, a prompt can be displayed reminding the user to wipe the water off the screen before attempting fingerprint recognition again. Simultaneously, the prompt can also remind the user to wipe the touchscreen surface to improve the touch experience.

[0053] An embodiment of the present invention provides a device for identifying the risk of water ingress, comprising:

[0054] The detection unit is used to detect proximity data obtained by the proximity sensor.

[0055] The alarm unit is used to output a water ingress risk warning on the screen when the approach data is less than or equal to a preset alarm threshold.

[0056] Example 2

[0057] Figure 4 This is a configuration diagram of a proximity sensor for a smart terminal. Figure 5 This is a structural framework diagram of the device for identifying the risk of water ingress into a screen according to an embodiment of the present invention. The following will refer to... Figure 4-5 The present invention provides a detailed description of the device for identifying the risk of water ingress into a screen according to an embodiment of the present invention.

[0058] An embodiment of the present invention provides a device for identifying water ingress into a screen. By utilizing the existing proximity sensor of the smart terminal, the device detects the difference in the amount of signal received by the proximity sensor when there is water on the screen, thereby determining whether the surface of the smart terminal is wet.

[0059] First, the detection unit.

[0060] In this embodiment of the invention, the detection unit utilizes the existing proximity sensor in the smart terminal device as the detection tool.

[0061] In one embodiment, the proximity sensor is an infrared sensor.

[0062] In one embodiment, the detection unit is used to detect proximity data obtained by the proximity sensor.

[0063] In this embodiment of the invention, the principle of light reflection by the proximity sensor on the TP (Touch Panel) glass cover 101 is as follows:

[0064] The refractive index n(glass) is 1.53, and the refractive index n(air) is 1.

[0065] Principle of light refraction: n(glass) * sina = n(air) * sinb;

[0066] The angle at which total internal reflection occurs inside the glass is (at which point angle b is 90 degrees);

[0067] a = arcsin(1*sin90 / 1.53) = 40 degrees.

[0068] Therefore, it can be concluded that the angle of light refraction is 40 degrees when there are no obstacles on the surface of the TP (Touch Panel) glass cover (in the state of only air).

[0069] The principle of light reflection on the TP (Touch Panel) glass cover 101 by the proximity sensor is as follows:

[0070] The refractive index of water, n(water), is 1.33;

[0071] Principle of light refraction: n(glass) * sina = n(water) * sinc;

[0072] The angle at which light undergoes total internal reflection inside the glass is (at which point angle c is 90 degrees);

[0073] a = arcsin(1.33*sin90 / 1.53) = 59 degrees.

[0074] That is, in this embodiment of the invention, when there is water on the TP glass cover, the total internal reflection angle of the TP glass cover surface increases from 40 degrees to 59 degrees. This means that when there was no water on the glass cover, light with an angle greater than 40 degrees was reflected back to the receiving end, while light with an angle less than 40 degrees shone into the air. After there is water on the glass cover, light with an angle greater than 59 degrees is reflected back to the receiving end, while light with an angle less than 59 degrees shone into the water and then into the air. In this way, if there is water on the TP glass cover, the amount of signal received by the proximity sensor receiving end will decrease.

[0075] In one embodiment, the proximity sensor utilizes an infrared transmitting and receiving device. The transmitting device emits infrared light, and when an object is located a certain distance above the sensor, the object reflects the infrared light, which then enters the receiving device. When there are water droplets on the glass cover of the screen, more of the infrared light emitted by the infrared transmitting device will pass through the water into the air, and less infrared light will be reflected back and enter the receiving device.

[0076] Secondly, the alarm unit.

[0077] In this embodiment of the invention, the alarm unit is used to trigger a screen water immersion alarm based on proximity data results.

[0078] In one embodiment, an alarm threshold is preset in the infrared receiver or set by the user. A water level is considered to be present on the glass cover surface of the screen if the water level is less than or equal to the preset alarm threshold. If the water level is greater than the preset threshold, no water alarm is issued (i.e., there is no water on the screen surface, so no water alarm is issued) or the alarm is reset.

[0079] In one embodiment, when there is water on the surface of the TP glass cover, if the signal received by the proximity sensor receiver is less than or equal to a preset alarm threshold, it is considered that there is water on the surface of the TP glass cover, and a water immersion warning is issued to the user's startup screen and / or terminal.

[0080] In one embodiment, the alarm when there is water on the surface of the TP glass cover includes: immediately executing an alarm action; or recording and monitoring risk warnings, and when the number of times the risk warning for water ingress on the screen is detected exceeds a threshold within a preset period, then issuing a warning about the risk of water ingress on the screen or executing a shutdown action.

[0081] In one implementation, the number of times threshold is a positive integer greater than or equal to 1.

[0082] In one embodiment, the alarm for water on the TP glass cover surface includes: risk warnings via a screen, and / or speaker, and / or light, and / or vibration device.

[0083] In one embodiment, the alarm for water on the TP glass cover surface includes alarms such as vibration, sound, flashing indicator lights, and / or displaying reminder text on the screen.

[0084] In one embodiment, the alarm is terminated when the signal received by the proximity sensor receiver exceeds a preset alarm threshold; or, the alarm is restored without prompting the user's startup screen and / or terminal with a water immersion warning.

[0085] In one implementation, a proximity sensor continuously collects signals. If the signal indicates the presence of water, the time of alarm activation and the duration of the alarm are recorded. A longer alarm duration indicates a greater risk of water ingress. Simultaneously, the smart terminal can also upload this data to a cloud server for storage, allowing the time of water ingress and its duration to be recorded in the vicinity of the smart terminal.

[0086] Example 3

[0087] Figure 6 This is a schematic diagram of the structure of an electronic device according to an embodiment of the present invention, such as... Figure 6 As shown, at the hardware level, this electronic device includes a processor, and optionally also includes a bus, a network interface, and memory. The memory may include main memory, such as high-speed random-access memory (RAM), or non-volatile memory, such as at least one disk drive. Of course, this electronic device may also include other hardware required for other business operations.

[0088] Processors, network interfaces, and memory can be interconnected via buses, which can be ISA (Industry Standard Architecture) buses, PCI (Peripheral Component Interconnect) buses, or EISA (Extended Industry Standard Architecture) buses, etc. Buses can be categorized as address buses, data buses, control buses, etc. For ease of representation, Figure 6 The symbol is represented by a single double-headed arrow, but this does not mean that there is only one bus or one type of bus.

[0089] Memory is used to store programs. Specifically, programs can include program code, which includes computer operation instructions.

[0090] The processor reads the corresponding computer program from non-volatile memory into memory and then runs it, forming a shared resource access control device at the logical level. The processor executes the program stored in memory and specifically performs the steps of the aforementioned method for identifying water damage to the screen.
