[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0039] Please see Figures 1 to 8 This application proposes a display panel PL, which includes a repeating unit RU, a hinge member 100 and a detection component 200. The repeating unit RU includes a plurality of pixel islands 300, and each pixel island 300 includes at least one sub-pixel. The two ends of the hinge member 100 are respectively connected to two adjacent pixel islands 300. The detection component 200 is connected to the hinge member 100.

[0040] In this embodiment, the display panel PL is configured in a first state, the spacing between two adjacent pixel islands 300 is a first spacing d1, and the resolution of the display panel PL is a first resolution; the display panel PL is configured in a second state, the spacing between two adjacent pixel islands 300 is a second spacing d2, and the resolution of the display panel PL is a second resolution.

[0041] In this embodiment, the first spacing d1 is smaller than the second spacing d2, and the first resolution is smaller than the second resolution.

[0042] It should be noted that the display panel PL has the same resolution in both stretched and unstretched states. However, when the display panel PL is used for large-screen display, the unit light-emitting area of ​​the display panel PL decreases, leading to technical problems such as dark spots or color differences after stretching, which affects the display effect. This application addresses this issue by setting a detection component 200 and a hinge component 100 within the display panel PL to obtain the state of the display panel PL. When the distance between two adjacent pixel islands 300 in the display panel PL is a smaller first distance d1, the resolution of the display panel PL is configured to be the smaller first resolution. When the distance between two adjacent pixel islands 300 in the display panel PL is a larger second distance d2, the resolution of the display panel PL is configured to be the larger second resolution. This increases the resolution of the display panel PL after stretching, improving the technical problems of dark spots or color differences when the display panel PL is used for large-screen display and enhancing the display effect of the display panel PL.

[0043] It should be noted that the first state of this application can be the state in which the display panel PL is in a small screen display state, and the second state of this application can be the state in which the display panel PL is in a large screen display state.

[0044] It should be noted that the detection component 200 of this application is configured to obtain the spacing between two adjacent pixel islands 300 in the display panel PL based on the deformation state of the hinge member 100.

[0045] For example, please see Figure 2 and Figure 3In this application, the pixel islands 300 can be connected to each other in four directions via hinge members 100, and the hinge members 100 have a certain degree of elasticity. When the display panel PL switches from a small screen display to a large screen display, the hinge members 100 will deform, and when the display panel PL switches from a large screen display to a small screen display, the hinge members 100 can spring back, thereby restoring the display panel PL to its normal state. The detection component 200 is connected to the hinge members 100. When the hinge members 100 deform, the detection component 200 will deform along with them, thereby obtaining the degree of deformation of the hinge members 100, and thus obtaining the distance between two adjacent pixel islands 300 in the display panel PL.

[0046] In this embodiment, the repeating unit RU may include a first pixel island 310, a second pixel island 320, a third pixel island 330 and a fourth pixel island 340 arranged in an array and connected to each other. Each pixel island 300 may include at least one sub-pixel. For example, each pixel island 300 may include one or three sub-pixels. The following embodiment uses the example of a pixel island 300 including one sub-pixel for illustration.

[0047] Please see Figure 2 and Figure 3 The first pixel island 310 includes a red sub-pixel, the second pixel island 320 includes a green sub-pixel, the third pixel island 330 includes a blue sub-pixel, and the fourth pixel island 340 includes a red sub-pixel; in Figure 2 In the structure, the display panel PL is configured in a first state, the red sub-pixel in the fourth pixel island 340 is configured in a non-light-emitting state, and the first pixel island 310, the second pixel island 320, and the third pixel island 330 are configured in a light-emitting state; Figure 3 In the structure, the display panel PL is configured in a second state, and the first pixel island 310, the second pixel island 320, the third pixel island 330 and the fourth pixel island 340 are all configured to be in an emitting state.

[0048] In this embodiment, Figure 3 In the structure, when the display panel PL is configured for large-screen display, all four pixel islands 300 in the repeating unit RU are configured to be in an luminous state, that is, one repeating unit RU displays using four sub-pixels of RGBR as units; Figure 2 In the structure, when the display panel PL is configured for small screen display, the three pixel islands 300 in the repeating unit RU are configured to be in the light-emitting state, and one pixel island 300 is configured to be in the non-light-emitting state, that is, one repeating unit RU displays with three sub-pixels of RGB as units.

[0049] It should be noted that the number of pixel islands 300 in the repeating unit RU is not limited to the number of pixels in the repeating unit RU. Figure 2 The structure in the repeating unit RU, for example, can be arranged in the form of 2*3, 3*3 or 4*4.

[0050] It should be noted that, in Figure 2 In the structure, the initial spacing between two adjacent pixel islands 300 is m. When the display panel PL is configured in the first state, and the first spacing d1 between two adjacent pixel islands 300 is greater than or equal to m and less than 2m, the repeating unit RU can configure fewer pixel islands 300 to be in the luminous state, so that the display panel PL can display at a first resolution; Figure 3 In the structure, the display panel PL is configured in a second state. When the second resolution of two adjacent pixel islands 300 is greater than or equal to 2m, the repeating unit RU can configure more pixel islands 300 to be in an luminous state so that the display panel PL can display at a second resolution.

[0051] This application improves the technical problem of dark spots or color differences appearing on the display panel PL by setting a detection component 200 and a hinge component 100 inside the display panel PL. When the distance between two adjacent pixel islands 300 in the display panel PL is a small first distance d1, the number of pixel islands 300 configured to be in the light-emitting state in the repeating unit RU is small, that is, the resolution of the display panel PL is configured to be a small first resolution. When the distance between two adjacent pixel islands 300 in the display panel PL is a large second distance d2, the number of pixel islands 300 configured to be in the light-emitting state in the repeating unit RU is large, and the resolution of the display panel PL is configured to be a large second resolution. After the display panel PL is stretched, the resolution of the display panel PL is increased by increasing the number of pixel islands 300 configured to be in the light-emitting state. This improves the technical problem of dark spots or color differences appearing on the display panel PL when it is displayed on a large screen and improves the display effect of the display panel PL.

[0052] The technical solution of this application will now be described in conjunction with specific embodiments.

[0053] Please see Figure 4 and Figure 5 The hinge component 100 includes a bending portion 110, and the detection component 200 includes a capacitor 210, which is embedded in the bending portion 110.

[0054] In this embodiment, the present application provides the hinge member 100 with a bending portion 110 to provide the hinge member 100 with a spring-back capability. When the display panel PL switches from a small screen display to a large screen display, the pixel islands 300 inside the display panel PL move away from each other, and the hinge member 100 is stretched and deformed under the action of external force.

[0055] As the hinge component 100 is stretched, the curvature of the bend 110 also changes. Simultaneously, due to the change in the curvature of the bend 110, the distance between the two ends of the capacitor 210 disposed inside the bend 110 continuously increases. By measuring the voltage across the plates of the capacitor 210, the degree of deformation of the bend 110 can be calculated, and the distance between two adjacent pixel islands 300 in the display panel PL can be further obtained.

[0056] It should be noted that the display panel PL of this application may have capacitors 210 embedded only in the bending portion 110 of some hinge members 100, while the bending portion 110 of other hinge members 100 may not have capacitors 210.

[0057] Please see Figure 4 The hinge component 100 may further include a first connecting portion 120 and a second connecting portion 130, the first connecting portion 120 and the second connecting portion 130 being respectively connected to the two ends of the bending portion 110; the end of the first connecting portion 120 away from the bending portion 110 is connected to the pixel island 300, and the end of the second connecting portion 130 away from the bending portion 110 is connected to the adjacent pixel island 300.

[0058] In this embodiment, the two ends of the hinge member 100 are respectively used to connect two adjacent pixel islands 300, and the middle part of the hinge member 100 is designed as a U-shaped bend 110 to provide a spring-back function. One or more bends can be provided at the bend of the bend 110, and the capacitor 210 can be embedded in any bend of the bend 110. By embedding the capacitor 210 in the bend 110, this application can effectively monitor the stretching state of the display panel PL, thereby obtaining the degree of stretching of the display panel PL.

[0059] Please see Figure 5 and Figure 6 The capacitor 210 includes a first electrode plate 211 and a second electrode plate 212. The detection component 200 also includes a first wire 220 and a second wire 230. The first wire 220 and the second wire 230 are at least embedded in the bending portion 110, and the first wire 220 is connected to the first electrode plate 211, and the second wire 230 is connected to the second electrode plate 212.

[0060] In this embodiment, the detection component 200 further includes a housing 240, which is made of a deformable material and encloses the first wire 220, the second wire 230, and the capacitor 210. When the capacitor 210 is stretched, the housing 240 made of the deformable material can deform freely, thereby preventing the capacitor 210 from being damaged during stretching.

[0061] In this embodiment, the outer shell 240 is wound into a tubular shape, and the first electrode plate 211 and the second electrode plate 212 are arranged opposite to each other in the extending direction of the outer shell 240 and are both connected to the inner wall of the tubular outer shell 240. The outer shell 240, the first electrode plate 211 and the second electrode plate 212 together form a receiving cavity.

[0062] In this embodiment, the cavity is filled with a medium 213, which is liquid. When the capacitor 210 is charged, the medium 213 can store electrical energy. The sides of the first electrode 211 and the second electrode 212 that are far apart from each other are exposed and are respectively connected to the first wire 220 and the second wire 230.

[0063] Please see Figures 1 to 6 The capacitor 210 is configured to change the distance between the first plate 211 and the second plate 212 based on the deformation state to change the voltage across the capacitor 210, and the first wire 220 and the second wire 230 are configured to transmit voltage.

[0064] In this embodiment, when the hinge member 100 is stretched, the bending portion 110 deforms, and at the same time, the first plate 31 and the second plate 212 at both ends of the capacitor 210 move away from each other.

[0065] In this embodiment, since the electrostatic constant and dielectric constant inside the capacitor 210 can remain unchanged, assuming the capacitor energy Q=CU, the energy remains unchanged after the capacitor 210 is fully charged, i.e., Q remains unchanged, while C=εS / 4πkd, where ε is the dielectric constant, S is the area of ​​the first plate 211 and the second plate 212 facing each other, d is the distance between the first plate 211 and the second plate 212, and K is the electrostatic constant. Therefore, C=εS / 4πkd can be simplified to C=S / d, where S remains basically unchanged after the variable (stretchable) capacitor 210 is manufactured, i.e., C is inversely proportional to d, i.e., Q=CU can be simplified to Q=SU / d.

[0066] Meanwhile, since the charge Q inside the capacitor 210 remains basically unchanged after it is fully charged and there is no discharge path, the voltage across the capacitor 210 will also change when the distance d between the first plate 211 and the second plate 212 changes. Therefore, this application can determine the deformation state of the bent portion 110 by measuring the voltage or voltage difference across the capacitor 210.

[0067] In this embodiment, by establishing a correspondence between the deformation state of the bent portion 110 and the deformation of the display panel PL, the deformation of the display panel PL can be obtained through the voltage difference of the capacitor 210, thereby realizing the monitoring of the deformation of the display panel PL through the capacitor 210.

[0068] Please see Figure 7The detection component 200 also includes a switching transistor Tc, the output terminal of which is connected to one end of a capacitor 210 via a first wire 220; the other end of the capacitor 210 is grounded via a second wire 230.

[0069] In this embodiment, the control terminal of the switching transistor Tc is connected to the control signal line, and the control signal line transmits the control signal Gc. The timing of the control signal Gc is as follows: Figure 7 As shown, under the control of the control signal Gc, capacitor 210 achieves different functions through the switching transistor Tc.

[0070] Please see Figure 7 The detection component 200 also includes a charging circuit connected to the input of the switching transistor Tc, and the charging circuit is configured to charge the capacitor 210.

[0071] In this embodiment, the switching transistor Tc is turned on under the control of the control signal Gc. The charging circuit charges the capacitor 210 through the switching transistor Tc, so that the capacitor 210 reaches a saturated state. This is to prevent the insufficient charge of the capacitor 210 from affecting the voltage between the first plate 211 and the second plate 212, thereby affecting the misjudgment of the deformation of the display panel PL.

[0072] Please see Figure 7 The detection component 200 also includes a conversion circuit connected to the input of the switching transistor Tc. The conversion circuit is configured to convert the voltage difference change signal across the capacitor 210 into a digital signal and transmit the digital signal to the processor.

[0073] Please see Figure 7 The conversion circuit includes an ADC circuit, which converts the voltage difference change of capacitor 210 into a digital signal and transmits it to the processor for processing. The processor obtains the stretchability of the display panel PL based on the digital signal.

[0074] Please see Figure 6 and Figure 7 The charging circuit is connected to the input terminal of the switching transistor Tc via the first switch S1, and the conversion circuit is connected to the input terminal of the switching transistor Tc via the second switch S2.

[0075] Specifically, such as Figure 8 The timing diagram shown illustrates that when capacitor 210 needs to be charged, for example... Figure 8 During the A to B period, the control signal Gc is at a high level. At this time, the switching transistor Tc is turned on under the control of the high level. At the same time, the first switch S1 is closed and the second switch S2 is open. The charging voltage Vin in the charging circuit charges the capacitor 210 through the switching transistor Tc.

[0076] When it is necessary to calculate the voltage difference of capacitor 210, for example Figure 8 During the C to D period, the control signal Gc is at a high level. At this time, the switching transistor Tc is turned on, and at the same time, the first switch S1 is turned off and the second switch S2 is turned on. The conversion circuit obtains the voltage difference value of capacitor 210 and converts the voltage difference value into a digital signal.

[0077] For example, in the initial state, the distance between the first plate 211 and the second plate 212 of capacitor 210 is D0. When the display starts, capacitor 210 is charged with a charging voltage of Ui. After sufficient charging time, the charge of capacitor 210 after being fully charged is Q0=Ui*εS / 4πkD0.

[0078] After one frame of signal time, for example Figure 8 During the period from A to D, after the display panel PL is stretched, the voltage change of the two plates of capacitor 210 is obtained by detection as U1. At this time, the distance between the two plates of capacitor 210 can be expressed as: D1=4πkQ0 / Ui*εS, where Q0 and Ui are known quantities, K and ε are constants, π is pi, and S is a fixed value for the area of ​​the first plate 211 and the second plate 212 of capacitor 210 facing each other. That is, this application can obtain the distance between the first plate 211 and the second plate 212 of the stretched capacitor 210 as D1 through this calculation formula, and then compare it with D0 to obtain the distance change between two adjacent pixel islands 300 in the display panel PL at this time.

[0079] In the next frame, the capacitor 210 continues to be charged by the charging voltage Ui. The capacitor charge is obtained as Q1 by using the distance D1 between the first plate 211 and the second plate 212 in the capacitor 210 calculated in the previous frame. Then, the distance D2 between the first plate 211 and the second plate 212 in the capacitor 210 after the second stretch of the display panel is calculated. By repeating the calculation, the real-time stretching state of the display panel PL can be obtained.

[0080] In this embodiment, the change in the spacing between the plates in the capacitor 210 can be positively correlated with the spacing between two adjacent pixel islands 300. Therefore, this application can obtain the spacing between two adjacent pixel islands 300 based on the spacing between the plates in the capacitor 210.

[0081] Please see Figure 7 and Figure 8The switching transistor Tc, the first switch S1, the second switch S2, the conversion circuit, and the charging circuit are all integrated in the pixel island 300; at the same time, the first wire 220 and the second wire 230 are embedded in the bending part 110, the first connecting part 120 and the second connecting part 130, and are finally connected to the switching transistor Tc, the first switch S1, the second switch S2, the conversion circuit and the charging circuit integrated on the pixel island 300 along the first connecting part 120 and the second connecting part 130.

[0082] This application integrates the switching transistor Tc, the first switch S1, the second switch S2, the conversion circuit, and the charging circuit through the pixel island 300, thereby achieving centralized management of the switching transistor Tc, the first switch S1, the second switch S2, the conversion circuit, and the charging circuit, and facilitating connection to the processor and external power supply.

[0083] In this embodiment, embedding the first wire 220 and the second wire 230 within the bending portion 110, the first connecting portion 120, and the second connecting portion 130 can prevent the first wire 220 and the second wire 230 from tangling together and short-circuiting or breaking when the bending portion 110 is stretched.

[0084] In this embodiment, the processor includes a timing controller or a programmable gate array chip, and the processor is configured to obtain the spacing between two adjacent pixel islands 300 in the display panel based on digital signal calculations.

[0085] Specifically, the operation algorithm of the timing controller or programmable gate array is rewritten based on the relationship between the capacitance value of capacitor 210 and the distance between the boards. The calculation steps of the operation algorithm include:

[0086] The change in capacitance of capacitor 210 is calculated by the change in voltage drop; the change distance between the first plate 211 and the second plate 212 is calculated based on the change in capacitance of capacitor 210; the degree of stretching of hinge member 100 is calculated based on the change distance; the distance between two adjacent pixel islands 300 in display panel PL is obtained; and the light emission state of pixel islands in repeating unit is controlled based on the distance between adjacent pixel islands 300.

[0087] It should be noted that the capacitance change varies depending on the capacitor 210, and the specific calculation algorithm needs to be designed according to the specific capacitor 210. Therefore, after obtaining the voltage difference change of the capacitor 210, the processor can quickly calculate the stretching state of the display panel PL, thereby controlling the light emission of the pixel islands 300 in the display panel PL.

[0088] It should be noted that the processor of this application may also include a pixel island control module to run the above-described calculation method.

[0089] It should be noted that the display device in this application can be any product or component with display function, such as a mobile phone, tablet computer, television, monitor, laptop computer, digital photo frame, or navigator.

[0090] This application provides a display panel and a display device. The display panel includes a repeating unit, a hinge component, and a detection component. The repeating unit includes multiple pixel islands, and each pixel island includes at least one sub-pixel. The two ends of the hinge component are respectively connected to two adjacent pixel islands. The detection component is connected to the hinge component. This application obtains the state of the display panel by setting the detection component and the hinge component inside the display panel. When the distance between two adjacent pixel islands in the display panel is a smaller first distance, the resolution of the display panel is configured to a smaller first resolution. When the distance between two adjacent pixel islands in the display panel is a larger second distance, the resolution of the display panel is configured to a larger second resolution. This improves the technical problem of dark spots or color differences appearing on the display panel when it is displayed on a large screen, and improves the display effect of the display panel.
