Description
Technical Field
[0001] The present invention generally relates to the field of display technology, and in particular to a touch-controlled electronic device and a control method thereof. Background Art
[0002] Small-sized touch-screen electronic devices such as sports cameras, and wearable devices such as watches and bracelets generally have a waterproof function, which prevents water from entering the device and causing damage to the device.
[0003] In addition, in addition to the waterproof function, the above-mentioned devices generally need to have an anti-mistaken touch function to solve the problem of poor touch when the device enters and exits water. At present, at least two metal detection contacts are generally set on the device. When entering the water, due to the conductivity of water, the metal detection contacts are turned on, and it can be determined that the device has entered water. At this time, the touch function of the device can be turned off, otherwise the touch function of the device is turned on. However, since the metal detection contacts use the electrical conductivity of water to achieve their own conduction, the device is required to provide an external current (current is discharged to the outside world). However, the above-mentioned devices are generally in direct contact with the human body, and the external current will pose certain safety hazards to the user. In addition, the metal detection contacts are generally exposed outside the device, which is easily corroded and damaged, resulting in poor or failure of the anti-mistaken touch function. Summary of the invention
[0004] The present application aims to provide a touch-controlled electronic device and a control method thereof, so as to solve the problems in the prior art of using metal detection contacts to prevent accidental touches, which may cause safety hazards and may lead to poor or ineffective anti-accidental touch functions.
[0005] In a first aspect, the present invention provides a touch-controlled electronic device, comprising:
[0006] A main body, wherein at least one brightness detection cavity is provided on the main body, at least part of the cavity wall of each brightness detection cavity is a water-induced light transmittance changing cavity wall, and the water-induced light transmittance changing cavity wall comprises a transparent layer and a water-induced light transmittance changing layer;
[0007] The water-induced light transmittance changing layer is arranged on a side of the transparent layer facing the brightness detection cavity, and a through hole is arranged on the cavity wall of the brightness detection cavity; or,
[0008] The water-induced light transmittance changing layer is arranged on a side of the transparent layer away from the brightness detection cavity;
[0009] The photosensitive element is arranged in each of the brightness detection cavities.
[0010] As an implementable manner, the brightness detection cavity includes a groove arranged on the main body, the opening of the groove is covered with a shielding member, and the shielding member serves as the water-induced transmittance change cavity wall.
[0011] As an implementable manner, the water-induced light transmittance changing cavity wall is a water-induced transparent cavity wall.
[0012] As an implementable manner, the water-induced light transmittance varying layer is a water-induced transparent ink layer.
[0013] As an implementable manner, a plurality of the brightness detection cavities are disposed on the back side and / or the side of the main body, and the photosensitive element is disposed in each of the brightness detection cavities.
[0014] As an implementable manner, four brightness detection cavities are provided on the back and / or side of the main body, the four brightness detection cavities are evenly arranged in the circumferential direction of the main body, and each brightness detection cavity is close to the back edge of the main body.
[0015] As possible implementation methods, it also includes:
[0016] Touch unit;
[0017] The control unit is used to control whether the touch control unit is in sleep mode or not according to the detection amount of the photosensitive element.
[0018] As an implementable manner, the method for controlling whether the touch control unit is put into sleep mode or not according to the detection amount of the photosensitive element is specifically as follows:
[0019] If the brightness value represented by the detection amount of the photosensitive element meets the sleep condition, the touch control unit is controlled to sleep; otherwise, the touch control unit is controlled to be in an activated state.
[0020] As an implementable method, when a plurality of the brightness detection cavities are provided on the main body, the control unit is used to determine whether at least one brightness value represented by the detection amount of each photosensitive element in the plurality of brightness detection cavities satisfies the sleep condition. If so, the touch control unit is controlled to sleep; if not, the touch control unit is controlled to be in an activated state.
[0021] In a second aspect, the present invention provides a control method for the touch-controlled electronic device as described above, comprising the following steps:
[0022] Acquiring the brightness value in each brightness detection cavity;
[0023] It is determined whether the brightness value satisfies a sleep condition. If so, the touch control unit of the touch-sensitive electronic device is controlled to sleep; if not, the touch control unit of the touch-sensitive electronic device is controlled to be in an activated state.
[0024] In the above scheme, at least part of the cavity wall of the brightness detection cavity is a water-induced transmittance change cavity wall. After the touch-controlled electronic device enters water, the water will contact the water-induced transmittance change layer of the water-induced transmittance change cavity wall, causing the transmittance of the water-induced transmittance change layer to change. Correspondingly, the amount of light that can enter the brightness detection cavity from the outside increases or decreases, and the brightness in the brightness detection cavity changes accordingly. The photosensitive element senses the brightness value in the brightness detection cavity, and the touch-controlled electronic device can determine whether it has entered water based on the brightness value. Compared with setting a metal detection contact on the touch-controlled electronic device and determining whether the touch-controlled electronic device has entered water based on whether the metal detection contact is turned on, it does not need to provide an external current, so it is safer, and there is no problem of safety hazards to the user due to the external current. In addition, since the scheme adopts a photoelectric detection method, and the photosensitive element is located in the brightness detection cavity, it can be protected by the brightness detection cavity, so it is not easy to fail, ensuring the reliability and life of use.

[0033] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.
[0034] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0035] like Figure 1-Figure 3 As shown, an embodiment of the present invention provides a touch-controlled electronic device, which is, for example but not limited to, a smart watch, a smart bracelet, a sports camera, etc., and includes:
[0036] A main body 1, wherein at least one brightness detection cavity 2 is disposed on the main body 1, wherein at least part of the cavity wall of each brightness detection cavity 2 is a cavity wall with water-induced light transmittance variation, wherein the cavity wall with water-induced light transmittance variation comprises a transparent layer and a water-induced light transmittance variation layer, wherein the water-induced light transmittance variation layer is disposed on a side of the transparent layer facing the inside of the brightness detection cavity, and a through hole is disposed on the cavity wall of the brightness detection cavity 2;
[0037] The water-induced transmittance-changing cavity wall mentioned here means that after the cavity wall comes into contact with water, it will change the transmittance according to the specific characteristics of the water-induced transmittance-changing layer, such as increasing the transmittance or decreasing the transmittance, so as to change the amount of external light irradiated into the brightness detection cavity 2, to change the brightness of the brightness detection cavity 2, and accordingly, the cavity wall will return to its initial state after being separated from water; if the transmittance of the water-induced transmittance-changing layer increases after contacting water, then the transmittance will decrease after separation from water; if the transmittance of the water-induced transmittance-changing layer decreases after contacting water, then the transmittance will increase after separation from water.
[0038] The transparent layer may be, for example but not limited to, a transparent sheet, such as a transparent glass sheet, a transparent ABS (Acrylonitrile Butadiene Styrene; acrylonitrile-butadiene-styrene copolymer) sheet, etc. In addition to being a sheet structure, the transparent layer may also be set to a structure adapted to the specific shape of the water-induced light transmittance changing cavity wall. The water-induced light transmittance changing material may be formed on one side of the transparent sheet by spraying or coating to form a water-induced light transmittance changing layer. The color of the water-induced light transmittance changing material may be selected according to actual needs. For example, a white water-induced light transmittance changing material is used in this example.
[0039] For the brightness detection cavity 2, the water-induced light transmittance changing layer is arranged on the side of the transparent layer facing the brightness detection cavity 2, so as to prevent the water-induced light transmittance changing layer from being worn away and losing the light shielding function when not in contact with water.
[0040] The photosensitive element 3 is disposed in each of the brightness detection cavities 2. The photosensitive element 3 is used to convert the light signal into an electrical signal, and is, for example but not limited to, a photoresistor.
[0041] In the above scheme, at least part of the cavity wall of the brightness detection cavity 2 is a water-induced transmittance change cavity wall. After the touch-controlled electronic device enters water, the water will contact the water-induced transmittance change layer of the water-induced transmittance change cavity wall, so that the transmittance of the water-induced transmittance change layer changes. Correspondingly, the amount of light that can enter the brightness detection cavity 2 increases or decreases, and the brightness in the brightness detection cavity 2 changes accordingly. The photosensitive element 3 senses the brightness value in the brightness detection cavity 2, and the touch-controlled electronic device can determine whether it has entered water based on the brightness value. Compared with setting a metal detection contact on the touch-controlled electronic device, determining whether the touch-controlled electronic device has entered water based on whether the metal detection contact is turned on, there is no need to provide an external current, so the safety is higher, and there is no problem of safety hazards to the user due to the external current. In addition, since the scheme adopts a photoelectric detection method, and the photosensitive element 3 is located in the brightness detection cavity 2, it can be protected by the brightness detection cavity 2, so it is not easy to fail, ensuring the reliability and life of use.
[0042] In addition to being arranged on the side of the transparent layer facing the brightness detection cavity, the water-induced transmittance changing layer can also be arranged on the side of the transparent layer away from the brightness detection cavity. In the case where the water-induced transmittance changing layer is arranged on the side of the transparent layer away from the brightness detection cavity, no through hole may be arranged on the cavity wall of the brightness detection cavity. In the case where the water-induced transmittance changing layer is arranged on the side of the transparent layer away from the brightness detection cavity, that is, the water-induced transmittance changing layer is arranged outside the brightness detection cavity, when the touch-sensitive electronic device contacts water, compared with the above example, the water-induced transmittance changing layer in this example can directly contact water without waiting for water to flow into the brightness detection cavity from the through hole before contacting the water-induced transmittance changing layer to change its transmittance, so the reaction is faster and the hole opening process is omitted; in addition, since water does not need to enter the brightness detection cavity, the photosensitive element can be better protected and the current can be prevented from being discharged.
[0043] As an implementable manner, in order to facilitate manufacturing, the brightness detection cavity 2 includes a groove 21 provided on the main body 1, for example but not limited to, if the main body 1 includes a plastic shell, the groove 21 can be integrally injection molded with the plastic shell, or can be grooved by material removal processing, and the opening of the groove 21 is covered with a shielding member 22, and the shielding member 22 serves as the water-induced light transmittance change cavity wall. The shielding member 22 is, for example but not limited to, a sheet structure, and the shielding member 22 includes a light-transmitting portion and a water-induced light transmittance change layer provided on the light-transmitting portion, and the water-induced light transmittance change layer is located on the side of the light-transmitting portion facing the groove 21 or the water-induced light transmittance change layer is located on the side of the light-transmitting portion away from the groove 21.
[0044] In the case where the water-induced light transmittance changing layer is located on the side of the light-transmitting portion facing the groove 21, a through hole needs to be provided, and the through hole is, for example but not limited to, provided on the shielding member 22. Of course, according to actual conditions, the through hole can also be provided at other positions of the brightness detection chamber 2 except the shielding member 22. If the shielding member 22 is a transparent member such as a transparent glass sheet or a transparent ABS sheet, the entirety of the shielding member is a light-transmitting portion, and the water-induced light transmittance changing layer can be formed on one side of the entirety of the shielding member 22. If only a portion of the shielding member 22 is transparent, the water-induced light transmittance changing layer can be formed only on the transparent portion.
[0045] As an implementable manner, the water-induced light transmittance variation cavity wall is a water-induced transparent cavity wall. After the water-induced light transmittance variation cavity wall contacts water, it becomes transparent, and the brightness change in the brightness detection cavity is more obvious, which can improve the accuracy of measurement.
[0046] As an implementation method, the water-induced light transmittance changing layer is a water-induced transparent ink layer. The water-induced transparent ink layer can be formed by spraying or coating the water-induced transparent ink on one side of the transparent layer.
[0047] As an implementable manner, for the convenience of processing, a plurality of brightness detection cavities 2 are provided on the back of the main body 1, and the photosensitive element 3 is provided in each brightness detection cavity 2. In this example, four grooves 21 are provided on the back of the main body 1, and the opening of each groove 21 is covered with a shielding member 22, and each groove 21 and the shielding member 22 enclose a brightness detection cavity 2, and the four brightness detection cavities 2 are evenly arranged in the circumferential direction of the main body 1, and each brightness detection cavity 2 is close to the back edge of the main body 1.
[0048] As an implementable method, see also Figure 4-Figure 6As shown, in order to improve the reliability and sensitivity of detection, a plurality of brightness detection cavities 2 are provided on the side of the main body 1, and the photosensitive element 3 is provided in each brightness detection cavity 2. The brightness detection cavity 2 is provided on the side of the main body 1 so as not to be easily blocked by the user. For example, when the touch-controlled electronic device is a smart watch, the brightness detection cavity 2 is located on the side of the smart watch. When the smart watch is worn on the wrist of the user, since the side will not be blocked by the wrist, it can prevent the user from blocking the brightness detection cavity 2 and making the photosensitive element 3 unable to detect. In this example, four grooves 21 are provided on the side of the main body 1, and the opening of each groove 21 is covered with a shielding member 22. Each groove 21 and the shielding member 22 enclose a brightness detection cavity 2. The four brightness detection cavities 2 are evenly arranged in the circumferential direction of the main body 1, and each brightness detection cavity 2 is close to the back edge of the main body 1. Since the four brightness detection cavities 2 are evenly arranged in the circumferential direction of the main body 1, no matter at what angle the touch-sensitive electronic device is immersed in water, water will enter at least one brightness detection cavity 2. After water enters any brightness detection cavity 2, the change in brightness in the brightness detection cavity 2 can be detected by the photosensitive element 3 therein, thereby improving the sensitivity of detection.
[0049] As possible implementation methods, it also includes:
[0050] Touch control unit; the touch control unit includes, for example, a touch control IC (Integrated Circuit) and a touch control substrate.
[0051] The control unit is used to control whether the touch control unit is in sleep mode or not according to the detection amount of the photosensitive element 3.
[0052] As an implementable manner, the method for controlling whether the touch control unit is in sleep mode or not according to the detection amount of the photosensitive element 3 is specifically as follows:
[0053] If the brightness value represented by the detection amount of the photosensitive element 3 meets the sleep condition, the touch control unit is controlled to sleep; otherwise, the touch control unit is controlled to be in an activated state.
[0054] The sleep conditions mentioned here are mainly divided into two situations. If the water-induced light transmittance change cavity wall reduces the light transmittance when it encounters water, then the brightness value represented by the detection quantity is less than or equal to the sleep threshold value to satisfy the sleep condition. If the water-induced light transmittance change cavity wall increases the light transmittance when it encounters water, then the brightness value represented by the detection quantity is greater than or equal to the sleep threshold value to satisfy the sleep condition. Among them, the sleep threshold value used under the condition that the water-induced light transmittance change cavity wall reduces the light transmittance when it encounters water, and the sleep threshold value used under the condition that the water-induced light transmittance change cavity wall increases the light transmittance when it encounters water can be different values, which can be specifically determined according to the water-induced light transmittance change layer.
[0055] As described above, when the touch-sensitive electronic device is immersed in water, the water will contact the water-induced transmittance change cavity wall of the brightness detection cavity 2, so that the transmittance of the water-induced transmittance change cavity wall changes, and the amount of external light entering the water-induced transmittance change cavity wall changes, so that the brightness in the water-induced transmittance change cavity wall changes accordingly. When the brightness in the water-induced transmittance change cavity wall changes to a certain value, that is, when the sleep condition is met, the control unit controls the touch unit to sleep, such as the control unit sends a sleep signal to the touch IC of the touch unit to control the touch IC to stop scanning the touch substrate; after the touch-sensitive electronic device is out of water, the water will separate from the water-induced transmittance change cavity wall of the brightness detection cavity 2, so that the water-induced transmittance change cavity wall is restored to the initial state, that is, the brightness in the water-induced transmittance change cavity wall is restored to the state before entering the water. At this time, the brightness value does not meet the sleep condition, and the control unit controls the touch unit to activate, such as the control unit sends an activation signal to the touch IC of the touch unit to control the touch IC to start scanning the touch substrate.
[0056] As an implementable method, in order to improve the sensitivity of detection, when a plurality of the brightness detection cavities 2 are provided on the main body 1, the control unit is used to determine whether one or more brightness values represented by the detection quantities of the photosensitive elements 3 in the plurality of the brightness detection cavities 2 meet the sleep condition. If so, the touch control unit is controlled to sleep; if not, the touch control unit is controlled to be in an activated state.
[0057] For example, the touch-sensitive electronic device is immersed in water at an inclined angle, and only one of the water-induced transmittance change cavity walls of a brightness detection cavity 2 contacts water, and the transmittance of the water-induced transmittance change cavity wall changes accordingly. Correspondingly, the photosensitive element 3 therein detects that the brightness in the brightness detection cavity 2 also changes, while the water-induced transmittance change cavity walls of the remaining brightness detection cavities 2 do not contact water, and the brightness in the remaining brightness detection cavities 2 remains unchanged. It is then determined whether the detection amount of the brightness detection cavity 2 with the changed brightness meets the sleep condition. If so, the touch control unit is controlled to sleep; if not, the touch control unit is controlled to be in an activated state.
[0058] Second, as Figure 7 As shown, the present invention provides a control method for the above touch-controlled electronic device, comprising the following steps:
[0059] S1: Obtaining the brightness value in each brightness detection cavity 2;
[0060] S2: Determine whether the brightness value satisfies a sleep condition, and if so, control the touch control unit of the touch-sensitive electronic device to sleep; if not, control the touch control unit of the touch-sensitive electronic device to be in an activated state.
[0061] The method is used to control the above-mentioned touch-controlled electronic device. The working principle and effect thereof are referred to in the above-mentioned touch-controlled electronic device embodiment, which will not be described in detail here.
[0062] It should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like used above to indicate orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.
[0063] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept.
