The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

The terms "first", "second" and the like in the description and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It is to be understood that the data so used are interchangeable under appropriate circumstances so that the embodiments of the present application can be practiced in sequences other than those illustrated or described herein, and distinguish between "first", "second", etc. The objects are usually of one type, and the number of objects is not limited. For example, the first object may be one or more than one. In addition, "and/or" in the description and claims indicates at least one of the connected objects, and the character "/" generally indicates that the associated objects are in an "or" relationship.

The cover plate of the electronic device provided by the embodiment of the present application will be described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

As shown in FIG. 1 and FIG. 2 , an embodiment of the present application discloses a cover plate of an electronic device. Optionally, the cover plate may be a back cover of an electronic device, or a transparent cover covering a display screen of the electronic device. Light cover. The cover plate disclosed in the embodiments 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 that are stacked in sequence. Optionally, both the first substrate 110 and the second substrate 150 may be structures made of transparent materials such as glass, and the first electrode layer 120 and the second electrode layer 140 may be structures made of metal materials such as indium tin oxide. The optical properties of the electrochromic layer 130 (eg, reflectance, transmittance, absorption, etc.) can be changed stably and reversibly under the action of an external electric field, thereby changing the color of the electrochromic layer 130 .

When the cover plate 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 a redox reaction under the action of the first voltage difference, thereby A color change occurs, thereby realizing the function of color-changing display. When the cover plate 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 are formed under the action of the pulse voltage difference The touch sensing structure can realize the touch function. Optionally, the touch sensing structure can replace the physical keys of the current electronic device, and the physical keys can be keys such as a lock screen key, a volume key, etc. Of course, the touch sensing structure here can also realize other touch operations, such as Zoom in and out of target areas, manipulate applications, and more.

Optionally, in order to enable the cover plate to achieve different functions in different time periods, the cover plate may be controlled by time division. Referring to FIG. 3 , in the first time period T1, the electrochromic layer 130 is in a 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 first electrode layer 120 and the second electrode layer 140. The voltage difference formed between the two electrode layers 140 causes the electrochromic layer 130 to produce different colors, thereby realizing color-changing display; in the second time period T2, the first electrode layer 120 and the second electrode layer 140 are composed of The touch sensing structure can use the capacitance change generated by itself during the touch process to sense the touch operation. At this time, the electrochromic layer 130 does not work, and a pulse voltage difference is formed between the first electrode layer 120 and the second electrode layer 140 . When the user performs a touch operation with a finger, a touch pen, etc., the capacitance of the part of the touch sensing structure located at the touch point will be affected, and the coordinates of the touch point can be obtained through the sensed signal change, so that the touch Click the area where the point is located for interactive control.

It should be noted that the above-mentioned first time period refers to the time period during which the cover plate performs discoloration display. During this time period, the user does not need to perform touch operation; the second time period refers to the time period when touch operation is required. segment, at this time, the cover does not display discoloration. Of course, the cover plate can also realize touch sensing while displaying discoloration. In this case, both the first voltage difference and the pulse voltage difference can be formed between the first electrode layer 120 and the second electrode layer 140 .

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, so as to realize the color-changing display of the cover plate. At the same time, the first electrode layer 120 and the second electrode layer 140 can A touch sensing structure is formed under the action of the pulse voltage difference. When a user performs a touch operation, the touch sensing structure can recognize the user's touch operation to realize the touch function. It can be seen that the cover plate disclosed in the embodiments of the present application can simultaneously realize the color-changing display function and the touch-control function through structural multiplexing, so that no additional physical buttons are required in the electronic device, and thus the structure of the electronic device can be simplified.

Optionally, the cover plate has a touch surface, and the touch sensing structure is disposed corresponding to the touch surface. The touch surface here may be the surface of the cover plate facing away from the display screen, and this surface may be provided with structures such as the camera module 400; The surface can also be a surface of the cover plate disposed on the same side as the display screen; the touch surface can also be a side surface of the cover plate. The second electrode layer 140 may 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 further away from the touch surface. close. When the cover plate is in the second time period, the second electrode layer 140 is loaded with a pulse voltage, so that a pulse voltage difference is formed between the first electrode layer 120 and the second electrode layer 140 . Since the second electrode layer 140 is closer to the touch surface, a pulse voltage is applied to the second electrode layer 140 to sense the touch operation more sensitively.

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

The driving part 200 can be electrically connected to the driving unit through the touch traces 300 , and the touch traces 300 and the sensing pixel unit 141 can be arranged on the same layer or on different layers, and are electrically connected by punching or the like. Relatively speaking, when the touch traces 300 and the sensing pixel units 141 are disposed on the same layer, the circuit structure of the cover plate is simpler, so that it is easier to form the cover, and at the same time, the electric power of the sensing pixel units 141 and the touch traces 300 can be improved. Connection reliability.

In an optional embodiment, the cover plate has a first area 101 and a second area 102 , and the first area 101 is located outside the second area 102 , that is, the first area 101 and the second area 102 do not overlap. When the cover plate is in the second time period, the sensing pixel unit 141 in the first area 101 and the part of the first electrode layer 120 in the first area 101 form a touch sensing structure under the action of the pulse voltage difference. At this time, a partial area of the cover plate forms a touch sensing structure, so as to realize the touch operation of the partial area, and other areas that do not need to recognize the touch operation do not participate in the touch recognition process, thereby reducing the control cost of the cover plate.

As mentioned above, the cover plate may be a back cover of the electronic device. Further optionally, the back cover includes a main body portion and an annular side portion disposed on the edge of the main body portion. The main body portion may be opposite to the display screen of the electronic device, and the annular The side can surround the display of the electronic device.

There is a first area 101 . When the main body is provided with the first area 101, the touch operation on the side of the back cover facing away from the display screen can be recognized, and this side is not often seen by the user, so this setting can obtain better appearance and texture; When there is the first area 101, the touch operation on the side of the back cover can be recognized. Since the annular side part is often held by the user, the first area 101 on the surface is more convenient for the user to perform the touch operation.

The foregoing describes the solution for recognizing the touch operation only in the first area 101 . In other embodiments, the entire surface of the cover plate can also recognize the touch operation. 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.

In an optional embodiment, in the direction perpendicular to the cover plate, the orthographic projections of all the sensing pixel units 141 are located within the orthographic projections of the first electrode layer 120 . In other words, all the sensing pixel units 141 are located above the first electrode layer 120 , and this arrangement can realize a self-capacitance sensing structure, which has the advantages of simple structure and small calculation amount. Further, as shown in FIG. 4 , each sensing pixel unit 141 can be arranged in a matrix along the first and second perpendicular directions, and this solution can form a single-layer capacitive touch structure. At this time, each sensing pixel unit 141 The distribution is more regular, which makes it easier to determine the coordinates of the touch point.

In another optional embodiment, in a 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 to implement multi-touch and having a faster recognition speed.

Further, as shown in FIG. 5 , the first electrode layer 120 includes a plurality of first strip parts 121 , the first strip parts 121 extend along the third direction, and the first strip parts 121 are arranged at intervals along the fourth direction cloth, the third direction here is perpendicular to the fourth direction; the second electrode layer 140 includes a plurality of second stripe parts 142, the second stripe parts 142 include at least one sensing pixel unit 141, and the second stripe parts 142 extend along the Extending in four directions, the second strip portions 142 are arranged at intervals along the third direction. This structure can form a double-layer mutual capacitance structure, which is more conducive to implementing multi-touch and improving the recognition speed, and at the same time, the strip-shaped first electrode layer 120 and the second electrode layer 140 are more convenient to arrange.

In order to match a better capacitance change and achieve a better shadow elimination effect, the sensing pixel unit 141 can be set as a diamond-shaped unit. Of course, the sensing pixel unit 141 can also be set as a rectangular unit or a structure of other shapes. This is not limited.

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 ion storage layer 170. between the electrolyte layers 160 . The electrolyte layer 160 can be made of a conductive material, which can provide compensation ions required by the electrochromic layer 130, and the ion storage layer 170 can play a role of storing corresponding counter ions when the electrochromic layer 130 undergoes a redox reaction , so that the entire cover plate reaches a state of charge balance.

The electrochromic layer 130 may be provided with only one layer or at least two layers. The at least two electrochromic layers 130 have different color changing parameters, and optionally, the at least two electrochromic layers 130 may produce different colors. In contrast, in the latter embodiment, the effect of color superposition or color complementation can be generated between the electrochromic layers 130 , thereby bringing about more color-changing display effects.
