[0013] When the input is the second input, a pulse voltage difference is controlled to be formed between the first electrode layer and the second electrode layer. Under the action of the pulse voltage difference, the first electrode layer and the second electrode layer form a touch sensing structure, and touch information is obtained through the touch sensing structure.

The control module is further configured to control a pulse voltage difference to be formed between the first electrode layer and the second electrode layer when the input is the second input. Under the action of the pulse voltage difference, the first electrode layer and the second electrode layer form a touch sensing structure, and the control module is further configured to obtain touch information through the touch sensing structure.

Detailed implementation manners

[0034] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0035] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0036] The cover plate of the electronic device provided by the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0037] like Figure 1 and Figure 2 As shown, the embodiment of the present application discloses a cover plate of an electronic device. Optionally, the cover plate can be a back cover of the electronic device, or a light-transmitting cover plate covering the display screen of the electronic device. The cover plate disclosed in the embodiment of the present application includes a first substrate 110, a first electrode layer 120, an electrochromic layer 130, a second electrode layer 140, and a second substrate 150 stacked in sequence. Optionally, the first substrate 110 and the second substrate 150 can both be structures made of transparent materials such as glass, and the first electrode layer 120 and the second electrode layer 140 can be structures made of metal materials such as indium tin oxide. The optical properties (such as reflectivity, transmittance, absorptivity, etc.) of the electrochromic layer 130 can undergo stable and reversible changes under the action of an external electric field, thereby changing the color of the electrochromic layer 130.

[0038] When the cover is in the first time period, a first voltage difference is formed between the first electrode layer 120 and the second electrode layer 140, and the electrochromic layer 130 undergoes an oxidation-reduction reaction under the action of the first voltage difference, thereby changing color, thereby realizing the function of color-changing display. When the cover is in the second time period, a pulse voltage difference is formed between the first electrode layer 120 and the second electrode layer 140, and the first electrode layer 120 and the second electrode layer 140 form a touch sensing structure under the action of the pulse voltage difference, thereby realizing the touch function. Optionally, the touch sensing structure can replace the physical buttons of current electronic devices, and the physical buttons can be lock screen buttons, volume buttons, and other buttons. Of course, the touch sensing structure here can also realize other touch operations, such as zooming in and out of the target area, operating applications, etc.

[0039] Optionally, in order to enable the cover plate to realize different functions in different time periods, the cover plate can be controlled in time division. Figure 3, within the first time period T1, the electrochromic layer 130 is in the working state. At this time, the voltages of the first electrode layer 120 and the second electrode layer 140 can be controlled, so as to control the voltage difference formed between the first electrode layer 120 and the second electrode layer 140, making the electrochromic layer 130 generate different colors, thereby realizing color-changing display; within the second time period T2, the touch sensing structure composed of the first electrode layer 120 and the second electrode layer 140 can sense touch operations by using the capacitance change generated during the touch process. At this time, the electrochromic layer 130 does not work, and a pulsed voltage difference is formed between the first electrode layer 120 and the second electrode layer 140. When the user performs a touch operation through a finger, a stylus, etc., the capacitance of the part of the touch sensing structure located at the touch point will be affected. The coordinates of the touch point can be obtained through the sensed signal change, so as to perform interactive control on the area where the touch point is located.

[0040] It should be noted that the above-mentioned first time period refers to the time period when the cover plate performs color-changing display. In this time period, the user does not need to perform touch operations; the second time period refers to the time period when touch operations need to be performed. At this time, the cover plate does not perform color-changing display. Of course, the cover plate can also realize touch sensing while performing color-changing display. At this time, a first voltage difference and a pulsed voltage difference can be formed between the first electrode layer 120 and the second electrode layer 140 at the same time.

[0041] In the embodiment of the present application, the first electrode layer 120 and the second electrode layer 140 can drive the electrochromic layer to change color, thereby realizing the color-changing display of the cover plate. At the same time, the first electrode layer 120 and the second electrode layer 140 can form a touch sensing structure under the action of a pulsed voltage difference. When the user performs a touch operation, the touch sensing structure can identify the user's touch operation to realize the touch function. It can be seen that the cover plate disclosed in the embodiment of the present application can simultaneously realize the color-changing display function and the touch function through structure reuse, so that it is not necessary to additionally set physical buttons in the electronic device, thus simplifying the structure of the electronic device.

[0042] Optionally, the cover plate has a touch surface, and the touch sensing structure is arranged corresponding to the touch surface. Here, the touch surface can be the surface of the cover plate facing away from the display screen, and structures such as the camera module 400 can be arranged on this surface; the touch surface can also be the surface of the cover plate arranged on the same side as the display screen; the touch surface can also be the side surface of the cover plate. The second electrode layer 140 can be located on the side of the first electrode layer 120 facing the touch surface, that is, the second electrode layer 140 is located between the first electrode layer 120 and the touch surface, and the second electrode layer 140 is closer to the touch surface. When the cover plate is in the second time period, a pulsed voltage is applied to the second electrode layer 140 to form a pulsed voltage difference between the first electrode layer 120 and the second electrode layer 140. Since the second electrode layer 140 is closer to the touch surface, when a pulsed voltage is applied to the second electrode layer 140, touch operations can be sensed more sensitively.

[0043] The second electrode layer 140 that forms the touch sensing structure can include a plurality of sensing pixel units 141. The cover plate further includes a driving part 200. The first substrate 110 is provided with a plurality of driving units. The driving part 200 is electrically connected to each sensing pixel unit 141 through each driving unit, and the driving part 200 is electrically connected to the first electrode layer 120. At this time, the driving part 200 can respectively control the states of the plurality of sensing pixel units 141 through each driving unit, so as to sense touch operations with higher precision. It should be noted that the size of the sensing pixel unit 141 can be determined according to the touch precision. For example, the sensing pixel unit 141 can adopt a square structure, and its side length can be about 4 mm.

[0044] The driving part 200 can be electrically connected to the driving unit through the touch trace 300. The touch trace 300 and the sensing pixel unit 141 can be arranged on the same layer, or can be arranged on different layers and electrically connected by means of punching, etc. Relatively speaking, when the touch trace 300 and the sensing pixel unit 141 are arranged on the same layer, the circuit structure of the cover plate is simpler, so that it is easier to form the cover plate, and at the same time, the electrical connection reliability between the sensing pixel unit 141 and the touch trace 300 can also be improved.

[0045] In an optional embodiment, the cover plate has a first area 101 and a second area 102. The first area 101 is located outside the second area 102, that is to say, the first area 101 does not overlap with the second area 102. When the cover plate is in the second time period, the sensing pixel units 141 located in the first area 101 and the part of the first electrode layer 120 located in the first area 101 form a touch sensing structure under the action of the pulsed voltage difference. At this time, a touch sensing structure is formed in a local area of the cover plate, so as to realize touch operations in this local area, while other areas that do not need to recognize touch operations do not participate in the touch recognition process, thereby reducing the control cost of the cover plate.

[0046] As described above, the cover plate can be the rear cover of the electronic device. Further optionally, the rear cover includes a main body portion and an annular side portion provided at the edge of the main body portion. The main body portion can face away from the display screen of the electronic device, and the annular side portion can surround the display screen of the electronic device. At least one of the main body portion and the annular side portion can be provided with a first region 101. That is to say, the first region 101 can be provided only on the main body portion or the annular side portion, or the first region 101 can be provided on both the main body portion and the annular side portion at the same time. When the main body portion is provided with the first region 101, the touch operation on the side of the rear cover facing away from the display screen can be recognized. This side is not often seen by the user, so such a setting can obtain a better appearance texture. When the annular side portion is provided with the first region 101, the touch operation on the side of the rear cover can be recognized. Since the annular side portion is often held by the user, it is more convenient for the user to perform the touch operation by setting the first region 101 on this side.

[0047] The foregoing describes a solution for recognizing touch operations only within the first region 101. In other embodiments, it is also possible to enable the entire surface of the cover plate to recognize touch operations. That is, when the cover plate is in the second time period, all the sensing pixel units 141 and the first electrode layer 120 form a touch sensing structure under the action of the pulse voltage difference. This solution does not limit the position where the user performs the touch operation, so it is more convenient for the user to perform the touch operation.

[0048] In an alternative embodiment, in the direction perpendicular to the cover plate, the orthographic projections of all the sensing pixel units 141 are located within the orthographic projection of the first electrode layer 120. In other words, all the sensing pixel units 141 are located above the first electrode layer 120. This setting method can implement a self-capacitance sensing structure, which has the advantages of simple structure and small calculation amount. Further, as Figure 4 shown, each sensing pixel unit 141 can be arranged in a row matrix along the mutually perpendicular first direction and second direction. This solution can form a single-layer capacitive touch architecture. At this time, the distribution of each sensing pixel unit 141 is more regular, and it is further convenient to determine the coordinates of the touch point.

[0049] In another alternative embodiment, in the direction perpendicular to the cover plate, the orthographic projection of the first electrode layer 120 partially overlaps with the orthographic projection of the second electrode layer 140. At this time, the first electrode layer 120 and the second electrode layer 140 can form a mutual-capacitance sensing structure, which has the advantages of being more convenient for implementing multi-touch and faster recognition speed.

[0050] Further, as Figure 5As shown, the first electrode layer 120 includes a plurality of first strip portions 121. The first strip portions 121 extend along the third direction, and the first strip portions 121 are arranged at intervals along the fourth direction, where the third direction is perpendicular to the fourth direction; the second electrode layer 140 includes a plurality of second strip portions 142. The second strip portions 142 include at least one sensing pixel unit 141. The second strip portions 142 extend along the fourth direction, and the second strip portions 142 are arranged at intervals along the third direction. This structure can form a double-layer mutual capacitance architecture, which is more conducive to implementing multi-touch and improving the recognition speed. At the same time, the strip-shaped first electrode layer 120 and second electrode layer 140 are more convenient to arrange.

[0051] In order to match better capacitance changes and achieve a better shadow elimination effect, the sensing pixel unit 141 can be set as a rhombus unit. Of course, the sensing pixel unit 141 can also be set as a rectangular unit or a structure of other shapes. The embodiments of the present application do not limit this.

[0052] In an optional embodiment, the cover plate further includes an electrolyte layer 160 and an ion storage layer 170. The electrolyte layer 160 is disposed between the electrochromic layer 130 and the ion storage layer 170, and the ion storage layer 170 is disposed between the first electrode layer 120 and the electrolyte layer 160. The electrolyte layer 160 can be made of a conductive material, which can provide the compensation ions required by the electrochromic layer 130, and the ion storage layer 170 can play a role in storing the corresponding counter ions when the electrochromic layer 130 undergoes an oxidation-reduction reaction, so that the entire cover plate reaches a charge balance state.

[0053] The electrochromic layer 130 can be provided with only one layer, or at least two layers. The color change parameters of the at least two electrochromic layers 130 are different. Optionally, the at least two electrochromic layers 130 can produce different colors. Relatively speaking, the latter embodiment can cause a color overlay or color complementation effect between the electrochromic layers 130, thus bringing more color change display effects.

[0054] The embodiments of the present application also disclose an electronic device, which includes the cover plate described in any of the above embodiments.

[0055] The embodiments of the present application also disclose a control method for an electronic device. The control method is applied to the above electronic device and includes:

[0056] S100. Receive an input. The input here can specifically be a user input. The user can perform a target input operation by performing a touch operation on the display screen, and the target input operation can correspond to the function that the user hopes the electronic device to achieve.

[0057] S200. When the above input is the first input, control a first voltage difference to be formed between the first electrode layer 120 and the second electrode layer 140, and the electrochromic layer 130 changes color under the action of the first voltage difference. That is to say, the first input is the input for which color change display is required.

[0058] S300. When the above input is the second input, control a pulse voltage difference to be formed between the first electrode layer 120 and the second electrode layer 140. The first electrode layer 120 and the second electrode layer 140 form a touch sensing structure under the action of the pulse voltage difference, and touch information is obtained through the touch sensing structure. That is to say, the second input is the input for which touch recognition operation is required.

[0059] When the above control method is adopted, the color change display function and the touch function can be simultaneously realized through the first electrode layer 120 and the second electrode layer 140, so that it is not necessary to additionally provide physical buttons in the electronic device, and thus the structure of the electronic device can be simplified.

[0060] Optionally, controlling a pulse voltage difference to be formed between the first electrode layer 120 and the second electrode layer 140 in the above step S300 specifically includes: applying a pulse voltage to the second electrode layer 140 to form a pulse voltage difference between the first electrode layer 120 and the second electrode layer 140. Since the second electrode layer 140 is closer to the touch surface, applying a pulse voltage to the second electrode layer 140 can more sensitively sense touch operations.

[0061] Optionally, controlling a first voltage difference to be formed between the first electrode layer 120 and the second electrode layer 140 in the above step S200 specifically includes: applying a high-level signal to the first electrode layer 120 and applying a low-level signal to the second electrode layer 140, so as to form a first voltage difference between the first electrode layer 120 and the second electrode layer 140; controlling a pulse voltage difference to be formed between the first electrode layer 120 and the second electrode layer 140 in the above step S300 specifically includes: applying a high-level signal to the first electrode layer 120 and applying a pulse signal to the second electrode layer 140, so as to form a pulse voltage difference between the first electrode layer 120 and the second electrode layer 140. In this embodiment, the first electrode layer 120 is applied with a high-level signal both in the first time period and the second time period, thus simplifying the control method.

[0062] An embodiment of the present application also discloses a control device for an electronic device. This control device applies the above control method. The control device includes a receiving module and a control module, where: the receiving module is used to receive an input; the control module is used to control a first voltage difference to be formed between the first electrode layer 120 and the second electrode layer 140 when the input is a first input, and the electrochromic layer 130 changes color under the action of the first voltage difference. The control module is further used to control a pulsed voltage difference to be formed between the first electrode layer 120 and the second electrode layer 140 when the input is a second input, and the first electrode layer 120 and the second electrode layer 140 form a touch sensing structure under the action of the pulsed voltage difference. The control module is further used to obtain touch information through this touch sensing structure.

[0063] When the above control device is adopted, color-changing display and touch functions can be simultaneously realized through the first electrode layer 120 and the second electrode layer 140, so that there is no need to additionally set physical buttons in the electronic device, and thus the structure of the electronic device can be simplified.

[0064] The control device in the embodiment of the present application can be a device, or a component, an integrated circuit, or a chip in a terminal. The device can be a mobile electronic device or a non-mobile electronic device. Exemplarily, the mobile electronic device can be a mobile phone, a tablet computer, a notebook computer, a handheld computer, an in-vehicle electronic device, a wearable device, an ultra-mobile personal computer (UMPC), a netbook, or a personal digital assistant (PDA), etc. The non-mobile electronic device can be a server, a network attached storage (NAS), a personal computer (PC), a television (TV), a teller machine, or a self-service machine, etc. The embodiment of the present application does not make specific limitations.

[0065] The control device in the embodiment of the present application can be a device with an operating system. The operating system can be an Android operating system, an iOS operating system, or other possible operating systems. The embodiment of the present application does not make specific limitations.

[0066] Optionally, as Figure 6 shown, an embodiment of the present application further provides an electronic device 800, including a processor 810, a memory 820, and a program or instruction stored on the memory 820 and executable on the processor 810. When the program or instruction is executed by the processor 810, each process of the above control method is implemented, and the same technical effect can be achieved. To avoid repetition, it will not be elaborated here.
