[0038] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0039] refer to Figure 1 Figure 1 is a schematic diagram of the structure of a display provided by an embodiment of the present application. The display may be a display or display panel used to output content on an electronic device, such as a touch screen on a mobile phone or laptop. The technical solution in this embodiment is primarily used to sense whether the protective layer of the display is separated from the display layer, providing a timely reminder to prevent the protective layer from being replaced, thereby ensuring normal operation of the device. The display or display panel may be a flexible touch screen.

[0040] Specifically, the display in this embodiment may include the following structure:

[0041] Display layer 1;

[0042] Protective layer 2;

[0043] The detection layer 3 is located between the display layer 1 and the protective layer 2 , and the detection layer 3 can sense at least partial separation between the protective layer 2 and the display layer 1 .

[0044] For example, Figure 2As shown in the figure, the touch screen on the mobile phone consists of a protective film on the surface (protective layer 2) and a display screen on the bottom layer (display layer 1). A detection layer is set between the protective film and the display screen. If separation occurs between the protective film and the display screen, the detection layer can sense the separation state of the protective film and the display screen.

[0045] In one implementation, the detection layer may be a transparent conductive film, that is, a conductive layer, such as a metal layer or a transparent conductive film glass based on indium tin oxide (ITO).

[0046] As can be seen from the above technical solution, in a display according to an embodiment of the present application, a detection layer is disposed between the display layer and the protective layer of the display, so that the detection layer can sense at least partial separation between the protective layer and the display layer. Thus, in this embodiment, the detection layer is used to sense whether the protective layer is separated from the display layer, thereby providing a timely reminder not to replace the protective layer on your own, thereby ensuring normal use of the device.

[0047] In one implementation, the detection layer 3 and the display layer 1 form a detection capacitor, which can generate a capacitive signal. Specifically, the detection layer 3 and the protective layer 2 are integrated into one body, and the detection layer 3 and the display layer 1 serve as the two electrodes of the detection capacitor. If the distance between the detection layer 3 and the display layer 1 changes, that is, the distance between the two electrodes of the detection capacitor changes, the capacitive signal of the detection capacitor changes.

[0048] Based on this, the detection layer 3 can sense at least a partial separation between the protection layer 2 and the display layer 1 by using the capacitive signal.

[0049] For example, if the capacitance signal changes, it indicates that the distance between the protective layer 2 and the display layer 1 changes, and it can be determined that the display layer 1 and the protective layer are separated. Thus, the detection layer 3 can sense the separation between the protective layer 2 and the display layer 1.

[0050] Based on the above implementation, if the detection layer 3 senses the separation between the protective layer 2 and the display layer 1, the control chip in the display can be used to control the display layer 1 to output a prompt message, or the processor of the electronic device where the display is located can be used to control the display layer 1 to output a prompt message. Furthermore, the speaker in the electronic device where the display is located can be controlled to output a voice prompt, and the motor in the electronic device where the display is located can be controlled to vibrate to prompt that the separation of the protective layer is prohibited.

[0051] Based on the above implementation scheme, the display may further include a capacitive sensor 4, which may be provided on a control chip 5 of the display. Figure 3As shown in , the capacitive sensor 4 is connected to the detection layer 3, and the capacitive sensor 4 can collect the capacitive signal generated by the detection capacitor. Based on this, if the capacitive signal collected by the capacitive sensor 4 changes, then the separation between the protective layer 2 and the display layer 1 can be determined. At this time, the control chip 5 can respond to the change in the capacitive signal collected by the capacitive sensor 5 and control the display layer 1 to output a prompt message. The prompt message is used to prompt that the protective layer 2 and the display layer 1 are prohibited from being separated, such as "Do not tear off the protective film". Furthermore, the electronic device where the display is located can be controlled to output a voice prompt or vibration prompt to prompt that the protective film is prohibited from being torn off.

[0052] Specifically, the capacitive sensor 4 is connected to the detection layer 3 via a flexible printed circuit (FPC). Figure 4 As shown in the figure, the detection layer 3 is a metal layer, which is connected to the control chip IC (integrated circuit) of the touch screen through an FPC. A detection capacitor is formed between the metal layer and the display screen. If the protective film is torn, the distance between the protective film and the display screen changes. At this time, the capacitance signal generated by the detection capacitor changes, and the capacitance signal collected by the capacitance sensor changes. The capacitance sensor sends the changed state of the capacitance signal to the control IC. The control IC responds to the change in the capacitance signal and controls the touch screen to output a prompt message "Do not tear off the protective film". Furthermore, the mobile phone where the touch screen is located can also be controlled to output a voice prompt or vibration prompt to prompt that the protective film is prohibited from being torn off.

[0053] In another implementation, the detection layer 3 forms an electrical circuit with other components 6 in the display, such as Figure 5 As shown in , the other components 6 here may include at least conductive components such as FPC, control chip, etc. Based on this, the detection layer 3 can sense at least partial separation between the protective layer and the display layer using the electrical signal in the electrical circuit.

[0054] For example, Figure 6 As shown in the figure, the detection layer 3 can be an ITO layer, the ITO is connected to the FPC, and the FPC is connected to the control IC in the touch screen, thereby forming an electrical circuit between the ITO, FPC and the control IC. If the protective film is torn off the display screen, the electrical signal in the electrical circuit is interrupted, thereby determining that the protective film is torn. At this time, the control IC on the electrical circuit responds to the interruption of the electrical signal and controls the touch screen to output a prompt message of "Do not tear off the protective film". Furthermore, it can also control the mobile phone where the touch screen is located to output a voice prompt or vibration prompt to prompt that the protective film is prohibited from being torn off.

[0055] Based on the above implementation, the protective layer 2 at least includes: an optical adhesive layer 7 (in other implementations, the optical adhesive layer 7 is below the protective layer 2), namely an optical adhesive layer OCA (Optically Clear Adhesive). Based on this, the detection layer 3 is located between the optical adhesive layer and the display layer 1, such as Figure 7 As shown in , the detection layer 4 can be a conductive circuit to form an electrical circuit with other components 6. For example, the conductive circuit is connected to the control chip in the display through an FPC to form an electrical circuit.

[0056] For example, Figure 8 As shown in the figure, an OCA is provided behind the protective film, and a conductive circuit is between the OCA and the FPC. The conductive circuit is connected to the control IC on the touch screen motherboard through the FPC. If the electrical signal is interrupted, it can be determined that the electrical circuit is disconnected, and then it can be determined that the protective film is torn off. At this time, the control IC responds to the interruption of the electrical signal and controls the touch screen to output a prompt message of "Do not tear off the protective film". Furthermore, it can also control the mobile phone where the touch screen is located to output a voice prompt or vibration prompt to prompt that the protective film is prohibited from being torn off.

[0057] In one implementation, there is an overlapping area 8 between the display layer 1 and the protective layer 2 , and the detection layer 3 has at least one deployment position in the overlapping area 8 , and the deployment position is located in an edge area or a top corner area of the overlapping area.

[0058] For example, Figure 9 As shown in , the deployment positions include: four top corner areas on the overlapping area between the protection layer 2 and the display layer 1 on the display, such as the R corner area of the mobile phone touch screen.

[0059] For example, Figure 10 As shown in , the deployment position includes: an edge area on the overlapping area between the protection layer 2 and the display layer 1 on the display, such as the entire edge area of the touch screen of a mobile phone.

[0060] refer to Figure 11 , is a structural diagram of an electronic device provided in an embodiment of the present application. The electronic device may include a display 9, and of course may also include other components 10, such as a central processing unit (CPU), a graphics processing unit (GPU), a microphone, a speaker, a camera, etc. The electronic device provided in one embodiment of the present application is a folding device (folding mobile phone, folding large-screen device) with a flexible touch screen. The protective film can protect the flexible touch screen, including when the electronic device is in a folded state, the flexible touch screen is protected in a bent state, and when the electronic device is in an unfolded state, the flexible touch screen is protected in an unfolded state.

[0061] Specifically, the display 9 may include the following structure:

[0062] Display layer 1;

[0063] Protective layer 2;

[0064] The detection layer 3 is located between the display layer 1 and the protective layer 2 , and the detection layer 3 can sense at least partial separation between the protective layer 2 and the display layer 1 .

[0065] The specific implementation structure of the display 9 can be referred to in Figures 1 to 8 Any of the structures shown.

[0066] As can be seen from the above technical solution, in an electronic device according to an embodiment of the present application, a detection layer is disposed between the display layer and the protective layer of the display, so that the detection layer can sense at least partial separation between the protective layer and the display layer. Thus, in this embodiment, the detection layer is used to sense whether the protective layer is separated from the display layer, thereby providing a timely reminder not to replace the protective layer, thereby ensuring normal use of the device.

[0067] Taking a foldable screen mobile phone as an example, the technical solution of this application is illustrated below:

[0068] In one implementation, Figure 12 As shown in , the surface protective film of the mobile phone adds a conductive layer (such as ITO) in the R corner overlapping area, and the display area size of the R corner is adjusted by the software program. The conductive layer forms a detection capacitor with the screen. Based on this, a special overlapping area (deployment position) is set to detect the change of the capacitance signal. Therefore, if the user tears the R corner of the protective film, the capacitance signal of the four R corners will change. At this time, the mobile phone can detect the change of the capacitance signal through the capacitance sensor, and trigger the control IC of the display screen accordingly, and then control the IC to trigger a message to the software program. The software program controls the screen to pop up a "Do not tear the film" reminder page to the user, and at the same time add voice and vibration somatosensory prompts.

[0069] In another implementation, Figure 13 The figure shows an exploded view of the screen and screen support plate of a foldable phone, showing the layered structure of the phone's screen, which includes at least a protective film, an OCA layer, an FPC, and a control IC. A conductive circuit such as ITO is added to the OCA glue behind the protective film. The conductive circuit is connected to the control IC on the motherboard through the FPC of the screen. The motherboard detects the electrical signal in the electrical circuit formed by the conductive circuit. Once the protective film is torn off, the electrical signal will be interrupted, thereby judging whether the protective film is damaged. If the protective film is damaged, that is, the electrical signal is interrupted, the control IC triggers a message to the software program, and the software program controls the pop-up window on the screen: asking the user to go to after-sales service for processing.
