Description

Technical Field

[0001] This application belongs to the field of display technology, specifically relating to a display device, electronic device, and control method. Background Technology

[0002] In related technologies, the display device in electronic devices is installed on the mid-frame using adhesive, and the mid-frame and display device are sealed together, giving the electronic device a certain degree of water resistance, making it difficult for moisture from the everyday environment to enter between the display device and the mid-frame. However, as electronic devices are used over time, factors such as adhesive aging, prolonged accumulation of moisture at the connection between the display device and the mid-frame, and relative displacement between the mid-frame and the display device can all cause moisture to enter between the display device and the mid-frame. This moisture can then further penetrate the interior of the display device, causing aging and damage to internal components. Before obvious display abnormalities occur, users are unlikely to notice the moisture entering between the display device and the mid-frame, making it impossible to prevent moisture from entering in time. Summary of the Invention

[0003] This application aims to provide a display device, electronic device, and control method that at least solves the technical problem of moisture entering the electronic device through the space between the display device and the frame, thus damaging the display device, which is difficult to detect.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows:

[0005] In a first aspect, embodiments of this application provide a display device, which includes a display area and a non-display area disposed around the display area; the display device includes:

[0006] Display layer;

[0007] A detection layer is disposed on one side of the display layer, and the detection layer includes at least one detection capacitor located in the non-display area;

[0008] The control module is electrically connected to the detection capacitor. The control module is configured to acquire the capacitance value of the detection capacitor and generate influent aging information based on the change in the capacitance value of the detection capacitor.

[0009] Secondly, embodiments of this application provide an electronic device, including a housing and a display device provided in the first aspect, wherein the display device is disposed within the housing.

[0010] Thirdly, embodiments of this application propose a control method for an electronic device, which is applied to the electronic device as provided in the second aspect, and the method includes:

[0011] If the capacitance change of the detected capacitor is greater than or equal to a preset threshold, water inlet aging information is generated based on the capacitance change of the detected capacitor, and the display device is controlled to display the water inlet aging information.

[0012] In the display device provided in this application, by setting a detection layer and a detection capacitor in the detection layer, if any layer of the display device undergoes irreversible deformation, the detection capacitor located in the non-display area will also deform. The control module can analyze the change in the capacitance value of the detection capacitor to obtain water ingress aging information, so that the user can know the degree of water ingress aging of the display device in a timely manner through the water ingress aging information. Based on the degree of water ingress aging, the user can determine whether the display device needs to be repaired, so as to avoid further damage to the display device by water vapor to an irreparable state and improve the service life of the display device.

[0025] The following is combined Figures 1 to 5 A display device 10 according to an embodiment of this application is described.

[0026] like Figure 1 and Figure 2 As shown, this application embodiment provides a display device 10, which includes a display area AA and a non-display area NA surrounding the display area AA. The display device 10 includes a display layer 1, a detection layer 2, and a control module 3. The detection layer 2 is disposed on one side of the display layer 1 and includes at least one detection capacitor 31 located in the non-display area NA. The control module 3 is electrically connected to the detection capacitor 31 and is configured to acquire the capacitance value of the detection capacitor 31 and generate water ingress aging information based on the change in the capacitance value of the detection capacitor 31.

[0027] The display device 10 provided in this embodiment can be a non-bendable display device 10 or a bendable flexible display device 10. The display layer 1 enables the display device 10 to have a light-emitting display function. The detection layer 2 can be reused as any layer structure with a certain function, specifically it can be a touch layer with touch function, an adhesive layer with adhesive function, a driving circuit layer 5 with conductive function, a planarization layer with planarization function, etc.

[0028] The display device 10 may also include other layer structures besides the display layer 1 and the detection layer 2, including a substrate 4 and a driving circuit layer 5. The display layer 1 is located on one side of the substrate 4 and includes multiple light-emitting units. The driving circuit layer 5 is located on the side of the display layer 1 near the substrate 4 and is electrically connected to the light-emitting units to control the light-emitting units to emit light. For example, in this embodiment, an organic light-emitting diode (OLED) can be selected to fabricate the aforementioned light-emitting units. Alternatively, the light-emitting units can be set as micro light-emitting diodes (Micro-LEDs) or quantum light-emitting diodes (QLEDs). The driving circuit layer 5 may include multiple sub-pixel control units for controlling whether the light-emitting units emit light and the duration of light emission. The display device 10 in this embodiment may also include a cover plate 6, an optical adhesive 7, and a polarizer 8, etc., which will not be described in detail here.

[0029] Those skilled in the art will understand that external moisture can easily enter the display device 10 through the contact interfaces between the layers, i.e., from the side. At least some layers in the display device 10 are susceptible to corrosion by moisture, leading to irreversible deformation. Examples include the optical adhesive 7 and polarizer 8 in the display layer 1. Those skilled in the art will also understand that the capacitance value is related to the relative area of ​​the capacitor's electrodes and the spacing between the electrodes. Therefore, when irreversible deformation occurs in some layers of the display device 10, the detection capacitor 31 located in the non-display area NA will also deform, causing a change in its capacitance value. By acquiring the capacitance change of the detection capacitor 31 distributed in the non-display area NA, water ingress aging information can be analyzed. This water ingress aging information may include the degree of water ingress aging, the location of aging, etc. Users can use this water ingress aging information to know the degree of water ingress aging of the display device 10, and thus determine whether the display device 10 needs repair based on the degree of water ingress aging, in order to prevent the display device 10 from being further damaged by moisture to an irreparable state. Specifically, a mapping relationship between capacitance change value and water ingress aging degree can be obtained in advance through experiments. The control module 3 can then obtain the capacitance change value based on the obtained capacitance value and the initial capacitance value, and then generate the water ingress aging degree based on the capacitance change value and the mapping relationship. The initial capacitance value is the capacitance value of the detection capacitor 31 under the condition that no deformation has occurred in the structure of each layer.

[0030] In the display device 10 provided in this application, by setting a detection layer 2 in the display device 10 and setting a detection capacitor 31 in the detection layer 2, when any layer of the display device 10 undergoes irreversible deformation, the detection capacitor 31 located in the non-display area NA can also deform. The control module 3 can analyze the water ingress aging information by detecting the change in the capacitance value of the detection capacitor 31, so that the user can know the degree of water ingress aging of the display device 10 in a timely manner through the water ingress aging information. Based on the degree of water ingress aging, the user can determine whether the display device 10 needs to be repaired, so as to avoid further damage to the display device 10 by water vapor to an irreparable state and improve the service life of the display device 10.

[0031] Please continue reading. Figure 1 and Figure 3 In one embodiment, the detection layer 2 is a touch layer 3, which further includes a plurality of touch electrodes 32, at least partially located in the display area AA. By reusing the touch layer 3, the detection capacitor 31 can be fabricated simultaneously with the fabrication of the touch electrodes 32, thereby simplifying the fabrication steps of the display device 10.

[0032] The touch layer 3 enables touch operation of the display device 10. The touch layer 3 can be disposed on the light-emitting side of the display layer 1. To avoid the touch layer 3 affecting the display of the display layer 1, the touch layer 3 can be made of a light-transmitting material. At least some of the multiple touch electrodes 32 are located in the display area AA, and some touch electrodes 32 can also be disposed in the non-display area NA. The control module 3 can be a touch IC, and the touch electrodes 32 and the detection capacitor 31 are both electrically connected to the touch IC.

[0033] Multiple touch electrodes 32 can form multiple first touch electrode groups 32a and multiple second touch electrode groups 32b. The multiple first touch electrode groups 32a are arranged along a first direction X, and the multiple second touch electrode groups 32b are arranged along a second direction Y. Each first touch electrode group 32a includes multiple first touch electrodes arranged along the second direction Y, and each second touch electrode group 32b includes multiple second touch electrodes arranged along the first direction X. A touch capacitor is formed between adjacent first and second touch electrodes. The first direction X and the second direction Y are intersected. It should be noted that the aforementioned first touch electrode can be a detection driving electrode Tx, and the second touch electrode can be a detection sensing electrode Rx; or, the aforementioned first touch electrode can be a detection sensing electrode Rx, and the second touch electrode can be a detection driving electrode Tx. Furthermore, the number of first touch electrode groups 32a and second touch electrode groups 32b in the accompanying drawings is merely illustrative. The actual touch layer 3 can be configured with the required size and precision to accommodate the different numbers of first touch electrode groups 32a and second touch electrode groups 32b. Multiple first touch electrodes arranged along the second direction Y can be electrically connected in sequence, and multiple second touch electrodes arranged along the first direction X can be electrically connected in sequence. Multiple first touch electrode groups 32a and multiple second touch electrode groups 32b can be electrically connected to the control module 3 through signal lines, thereby sending the electrical signals of each touch capacitance change to the control module 3 so that the control module 3 can analyze and obtain the user's touch operation on the display area AA.

[0034] Those skilled in the art will understand that a capacitor is formed by at least two spaced electrodes. Therefore, in some embodiments, each detection capacitor 31 distributed in the detection layer 2 includes two detection electrodes located in the non-display area NA, with the two detection electrodes spaced apart from each other. In other embodiments, the touch layer 3 further includes a detection electrode 33, which is located in the non-display area NA and spaced apart from multiple touch electrodes 32, forming a detection capacitor 31 between the detection electrode 33 and the touch electrodes 32. That is, of the two electrodes forming the detection capacitor 31, one is a detection electrode 33 located in the non-display area NA, and the other is a touch electrode 32, thereby achieving the reuse of some touch electrodes 32 and simplifying the circuit distribution in the display device 10.

[0035] As described above, multiple touch electrodes 32 can form multiple first touch electrode groups 32a and multiple second touch electrode groups 32b. A detection electrode 33 can be spaced apart from the multiple touch electrodes 32 in a single touch electrode group. The detection electrode 33 can extend along the extending direction of the multiple touch electrodes 32, thus forming a detection capacitor 31 between the detection electrode 33 and the multiple touch electrodes 32. The detection electrode 33 can be elongated.

[0036] In other embodiments, the detection electrode 33 includes multiple sub-electrodes arranged sequentially along the side extension direction of the display area AA, forming a detection capacitor 31 between the sub-electrodes and the touch electrode 32. That is, in this embodiment, the detection electrode 33 has multiple sub-electrodes, each of which can form a detection capacitor 31 with the touch electrode 32. By observing the distribution of the multiple sub-electrodes, the degree of water ingress aging at different locations in the display device 10 can be determined by the change in capacitance value of each detection capacitor 31.

[0037] In some embodiments, the number of detection capacitors 31 is multiple, and the multiple detection capacitors 31 are arranged around the display area AA, so that the degree of water ingress and aging on each side of the display area AA can be monitored by the multiple detection capacitors 31. For example, if the display device 10 is rectangular, four detection capacitors 31 can be set, and the four detection capacitors 31 are respectively distributed on the four sides of the display device 10, and the four detection capacitors 31 are arranged around the display area AA.

[0038] Please see Figure 4 The non-display area NA includes a line output area 10a and multiple wiring areas 10b, which are connected in sequence. One end of the line output area 10a is connected to one end of the multiple wiring areas 10b, and the other end of the line output area 10a is connected to the other end of the multiple wiring areas 10b. The detection capacitor 31 is located in the wiring area 10b.

[0039] The signal lines connecting the detection capacitor 31 and the control module 3, as well as the signal lines connecting the contact electrode 32 and the control module 3, can all be converged in the wiring area 10b and then connected to the output area 10a before being connected to the control module 3. For example... Figure 4 In the illustrated embodiment, three wiring areas 10b are connected sequentially, and an output area 10a connects two wiring areas 10b and is spaced apart from another wiring area 10b on both sides of the display area AA. Compared to the wiring areas 10b, the conductive structures in the output area 10a are more complex, making it difficult to place the detection capacitor 31. By placing the detection capacitor 31 in the wiring area 10b, the arrangement of the circuit in the detection layer 2 is facilitated, and to a certain extent, the detection capacitor 31 is prevented from interfering with other circuit structures in the detection layer 2 besides the detection capacitor 31.

[0040] In some embodiments, the wiring area 10b extends along the side of the display area AA, and the detection capacitor 31 extends along the extending direction of the wiring area 10b. For example Figure 4 In the illustrated embodiment: the display area AA is rectangular, and a wiring area 10b extends along the side of the display area AA, which extends along the X-axis direction. Simultaneously, a detection capacitor 31 disposed in the wiring area 10b also extends along the X-axis direction. By setting the detection capacitor 31 to extend along the extension direction of the wiring area 10b, the detection capacitor 31 can detect more areas within the display device 10 along the edge of the display device 10.

[0041] The control module 3 is located on the side of the display layer 1 opposite to the functional layer 2. The signal line connecting the detection capacitor 31 and the control module 3 extends from the wiring area 10b to the output area 10a. The signal line in the output area 10a is at least partially bent to connect with the control module 3 located on one side of the display layer 1. The signal line connecting the contact control electrode 32 and the control module 3 can also extend from the wiring area 10b to the output area 10a, and can also extend from the display area AA to the output area 10a.

[0042] Please refer to the following: Figure 5 In some embodiments, the display device 10 is a flexible display device 10. When the display device 10 is a flexible display device 10, it has a folded state and a flat state. In the folded state, the flexible display device 10 is at least partially bent into an arc shape, and certain areas of the flexible display device 10 can be stacked on top of each other, thereby reducing the volume of the flexible display screen. In the flat state, the flexible display device 10 has a flat light-emitting surface, thereby obtaining a larger display area.

[0043] Those skilled in the art will understand that, because the flexible display device 10 can be bent for display, compared to a non-bendable display device 10, the layers in the flexible display device 10 are more prone to relative displacement during changes in folded and unfolded states. This makes it easier for external moisture to enter the flexible display device 10, causing aging of some layers. By placing the detection capacitor 31 in the non-display area NA of the flexible display device 10, the user can promptly know the degree of water ingress aging of the flexible display device 10.

[0044] The display device 10 may include a support layer 11, a first protective layer 12, and a cover plate 6, wherein the support layer 11, the first protective layer 12, the display layer 1, the touch layer 3, and the cover plate 6 are arranged sequentially along the thickness direction of the display device 10. The support layer 11 may be made of steel to support the other layer structures. The first protective layer 12 may be made of silicone to support the other layer structures. The cover plate 6 may be a thermoplastic polyester, such as polyethylene terephthalate.

[0045] In another embodiment, the flexible display device 10 may further include a polarizer 8, a second protective layer 13, and an adhesive layer 14, with the support layer 11, first protective layer 12, display layer 1, touch layer 3, polarizer 8, second protective layer 13, adhesive layer 14, and cover plate 6 arranged sequentially. The polarizer 8 is used to dissipate various stray light reflected from the metal traces in the display layer 1. The second protective layer 13 may be tempered glass to protect the display layer 1 and the touch layer 3. The adhesive layer 14 may be a transparent optical adhesive to bond the second protective layer 13 and the cover plate 6.

[0046] This application also provides an electronic device, including a housing and a display device 10 as described above, wherein the display device 10 is disposed within the housing.

[0047] In this embodiment of the application, the aforementioned electronic device may be any one of a mobile phone, a tablet computer, or a wearable device.

[0048] The electronic device according to the embodiments of this application may also include an antenna, a speaker, a fingerprint recognition module, etc. Other components and operations are known to those skilled in the art and will not be described in detail here.

[0049] Please see Figure 6 In some embodiments, the housing includes a middle frame that supports the display device 10. The middle frame includes a mounting plate 201, a side wall 202, and a top wall 203. The side wall 202 protrudes from the mounting plate 201, and the top wall 203 is connected to the side wall 202. The top wall 203 and the mounting plate 201 are spaced apart along the thickness direction of the display device 10. The non-display area NA of the display device 10 is disposed between the top wall 203 and the mounting plate 201, and the top wall 203 is connected to the non-display area NA.

[0050] Mounting plate 201 can be positioned to correspond to the display area AA and non-display area NA of display device 10, thereby increasing the support area for display device 10. When display device 10 is a flexible display panel, by placing the non-display area NA between top wall 203 and mounting plate 201, and connecting top wall 203 to non-display area NA, displacement between display device 10 and side wall 202 can occur. Top wall 203 and non-display area NA can be bonded together using double-sided adhesive.

[0051] This application also provides a control method for an electronic device, which is applied to the electronic device 100 described above. The method includes:

[0052] If the capacitance change of the detected capacitor is greater than or equal to a preset threshold, water inlet aging information is generated based on the capacitance change of the detected capacitor, and the display device is controlled to display the water inlet aging information.

[0053] Those skilled in the art can set a preset threshold as needed. The capacitance change value is the difference between the capacitance value obtained by the control module and the initial capacitance value. If the detected capacitance change value is greater than or equal to the preset threshold, it indicates that some areas of the display device have suffered severe water ingress and aging, requiring repair. After reading this water ingress aging information, users can send the electronic device to a repair shop for maintenance to prevent further water ingress and aging of the display device.

[0054] In another embodiment, after the control display device displays the influent aging information, it further includes:

[0055] Obtain repair shop information and the location information of electronic devices, and control the display device to display the repair shop information closest to the location information based on the location information and repair shop information.

[0056] By displaying the nearest repair center information based on the location, users can easily send their electronic devices to the corresponding repair center for timely repair, thus preventing further water damage and aging of the display device.

[0057] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
