[0024] 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 some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] With the development of display technology, display panels have evolved from rigid to flexible, and then to stretchable. Stretchable display technology allows display panels to be stretched in all directions like a rubber band to change shape and adapt to surfaces of any shape. Consumers can unfold, fold, flatten, or bend them as needed. However, stretching the display panel can cause pixel displacement, resulting in a decrease in display quality.

[0026] To address the aforementioned technical problems, this application provides a stretchable display panel, comprising: a substrate; a plurality of pixel units arranged in an array on one side of the substrate; a plurality of detection modules located between the substrate and the pixel units, each detection module corresponding one-to-one with the pixel units, and the detection modules being used to detect the amount of change of their respective pixel units before and after stretching; wherein each detection module includes a plurality of detection units, and the orthographic projection of each detection unit on the substrate at least partially overlaps with the orthographic projection of the corresponding pixel unit on the substrate; a controller, wherein the plurality of detection modules are electrically connected to the controller via wiring, and the controller is used to: control the plurality of detection units to acquire their respective first positions before stretching; control the plurality of detection units to acquire their respective second positions after stretching; and compensate the data signals based on the respective first positions before stretching and their respective second positions after stretching. In this application embodiment, by setting detection modules to detect the amount of change of pixel units before and after stretching, the subsequent controller uses the amount of change before and after stretching to correct the image, which can improve the image deformation caused by stretching and improve the display effect.

[0027] Figure 1 This is a schematic diagram of the structure of a stretchable display panel provided in one embodiment of this application. Figure 1 As shown, the stretchable display panel includes: a substrate 10, multiple pixel units 20 arranged in an array, and multiple detection modules 30.

[0028] In this embodiment, the substrate 10 needs to possess high elasticity, flexibility, and stretchability, while also requiring optical transparency and chemical stability. Optionally, the substrate 10 comprises a polymer material, such as at least one of polydimethylsiloxane (PDMS), thermoplastic polyurethane (TPU), polyimide (PI), silicone elastomer (Ecoflex), hydrogel, and other elastic polymers.

[0029] Pixel units 20 are located on one side of substrate 10. Pixel units 20 are arranged in an array; for example, multiple pixel units 20 are arranged along a first direction and a second direction, wherein the first direction and the second direction are perpendicular. In this embodiment, pixel unit 20 includes a first electrode, a light-emitting functional layer, and a second electrode sequentially stacked along a direction away from substrate 10. Optionally, the first electrode includes a cathode and the second electrode includes an anode; or, the first electrode includes an anode and the second electrode includes a cathode. In this embodiment, the first electrode is an anode and the second electrode is a cathode. Optionally, the first electrode is a reflective electrode, for example, including a stacked structure of a transparent conductive oxide layer / metal layer / transparent conductive oxide layer sequentially stacked, or a stacked structure of a metal layer / transparent conductive oxide layer sequentially stacked, or a single-layer structure including a metal layer. The transparent conductive oxide layer is made of indium tin oxide (ITO), indium tin oxide (IZO), etc. The metal layer is made of at least one of silver, aluminum, and gold. The second electrode is a semi-transmissive and semi-reflective electrode. The material of the second electrode includes single metals such as aluminum, silver, and magnesium, or alloys comprising any combination of these materials, such as magnesium-silver alloys or aluminum-lithium alloys. The second electrode is relatively thin, allowing it to possess both conductivity and light transmittance. This enables the light emitted from the light-emitting functional layer to be partially transmitted and partially reflected, thus forming an optical microcavity between the first and second electrodes. The microcavity effect enhances the light emission efficiency at the positive viewing angle.

[0030] Optionally, the light-emitting functional layer includes some or all of the following layers sequentially stacked along the direction away from the substrate: a hole injection layer, a hole transport layer, an electron blocking layer, a light-emitting layer, a hole blocking layer, an electron transport layer, and an electron injection layer. For example, when the first electrode is an anode and the second electrode is a cathode, the light-emitting functional layer includes the following layers sequentially stacked along the direction away from the substrate: a hole injection layer, a hole transport layer, an electron blocking layer, a light-emitting layer, a hole blocking layer, an electron transport layer, and an electron injection layer.

[0031] In this embodiment, the detection module 30 is located between the substrate 10 and the plurality of pixel units 20. The plurality of detection modules 30 correspond one-to-one with the plurality of pixel units 20. The plurality of detection modules 30 are used to detect the amount of change of their respective pixel units 20 before and after stretching.

[0032] In this embodiment, each detection module 30 includes multiple detection units, and the orthographic projection of each detection unit on the substrate 10 at least partially overlaps with the orthographic projection of the corresponding pixel unit 20 on the substrate 10. Thus, the stretching change of the detection unit can reflect the stretching change of the corresponding pixel unit 20, thereby determining the change in the pixel unit 20 before and after stretching. In this embodiment, the detection unit may include a displacement sensor. The displacement sensor can detect the displacement change. Since the pixel unit 20 may experience both stretching and rotation after stretching, multiple detection units can be used to determine the rotation change of the pixel unit by measuring the displacement changes of these multiple detection units. Optionally, the multiple detection units are used to detect both the stretching and rotation changes of the corresponding pixel unit 20. Each detection module 30 includes at least two detection units.

[0033] In this embodiment, the orthographic projection of the pixel unit 20 onto the substrate 10 includes at least one of a rectangle, rhombus, trapezoid, circle, and ellipse. The detection unit can be disposed inside the pixel unit 20; or, the detection unit can be disposed at the edge region of the pixel unit 20, as long as it can reflect the amount of stretching change of the pixel unit 20.

[0034] For example, Figure 2 yes Figure 1 An enlarged schematic diagram of one embodiment of region A of the display panel shown. (See diagram below.) Figure 2 As shown, the orthographic projection of pixel unit 20 onto substrate 10 comprises a rectangle. The detection module 30 includes two detection units 301, each positioned at one of the four corners of the rectangle, for example, at diagonally opposite corners. In other embodiments, the detection units 301 may be positioned at other locations. For example, the detection units 301 may be positioned at two adjacent corners. Alternatively, at least one detection unit 301 may be positioned along the side of the rectangle. Yet another example is that at least one detection unit 301 may be positioned inside the rectangle (e.g., at the center).

[0035] Figure 3 yes Figure 1 An enlarged schematic diagram of another embodiment of the display panel area A shown. (See diagram below.) Figure 3As shown, the orthographic projection of pixel unit 20 on substrate 10 includes a rectangle. Detection module 30 includes four detection units 301, which are respectively disposed at the four corners of the rectangle. In this embodiment, by setting four detection units 301, the detection results can be cross-checked, further improving detection accuracy. It is understood that the four detection units 301 can also be disposed in other positions. In this embodiment, other numbers of detection units 301 can also be provided. Optionally, if the orthographic projection of pixel unit 20 on substrate 10 includes a circle, detection module 30 can include two or more detection units 301, which can be respectively disposed on the edge of the circle. For example, if there are two detection units 301, the two detection units 301 can be respectively disposed at the position where the diameter of the circle intersects with the edge of the circle. As another example, if there are four detection units 301, the four detection units 301 can be evenly disposed on the edge of the circle, that is, the four detection units 301 can be respectively disposed at the position where two mutually perpendicular diameters intersect with the edge of the circle.

[0036] Figure 4 This is a structural schematic diagram of a stretchable display panel provided in another embodiment of this application. Figure 4 The stretchable display panel shown is Figure 1 The difference in the stretchable display panel shown is that the stretchable display panel also includes a controller 50, and multiple detection modules 30 are electrically connected to the controller 50 via wiring 40. For example... Figure 4 As shown, the stretchable display panel includes a display area AA and a non-display area NA, with the controller NA set in the non-display area NA.

[0037] In this embodiment of the application, the detection module 30 includes a plurality of detection units 301 (e.g., Figure 2 or Figure 3 (As shown). The controller 50 is used to control the multiple detection units 301 to acquire their respective first positions before stretching, and / or to control the multiple detection units 301 to acquire their respective second positions after stretching. Optionally, the controller 50 is also used to compensate the data signal based on the respective first positions of the multiple detection units 301 before stretching and their respective second positions after stretching. Specifically, the controller 50 is used to determine the change amount of each of the multiple pixel units before and after stretching based on the respective first positions of the multiple detection units 301 before stretching and their respective second positions after stretching; determine the compensation data of each of the multiple pixel units based on the change amount of each of the multiple pixel units before and after stretching; and send the compensation data of each of the multiple pixel units to the data voltage terminal to compensate the data signal.

[0038] In this embodiment, the controller 50 may be integrated on a chip, and / or the controller 50 may be integrated on a flexible circuit board. This embodiment does not impose any limitations.

[0039] In this embodiment, by setting a detection module and a controller, the detection module can detect the change in pixel units before and after stretching, and the controller can use the change in pixel units before and after stretching to correct the image, thereby improving the image deformation caused by stretching and enhancing the display effect.

[0040] This application also provides an image correction method applicable to the aforementioned stretchable display panel. The image correction method includes: acquiring the changes in each of multiple pixel units on the stretchable display panel before and after stretching; determining compensation data for each of the multiple pixel units based on their respective changes before and after stretching; and correcting the image based on the compensation data for each of the multiple pixel units. In this application embodiment, determining the compensation data for the pixel units based on their changes before and after stretching, and correcting the image based on the compensation data, can reduce or avoid image distortion caused by stretching, thereby improving the image display effect.

[0041] Figure 5 This is a schematic flowchart of an image correction method provided in an embodiment of this application. Figure 5 As shown, the method includes the following steps.

[0042] Step S510: Obtain the changes in each of the multiple pixel units on the stretchable display panel before and after stretching.

[0043] In this embodiment, the stretchable display panel is the same as the stretchable display panel described in the above embodiments. The changes in a pixel unit before and after stretching include both stretching and rotation. These changes can be determined using multiple detection units (e.g., displacement sensors). For example, if there are two detection units, the positional changes of these two units can reflect both stretching and rotation of the pixel unit. If there are more than two detection units (e.g., four), the positional changes of these four detection units can reflect both stretching and rotation of the pixel unit, and the detection results can be cross-checked to further improve detection accuracy. For a method to determine the changes in a pixel unit before and after stretching, see [link to relevant documentation]. Figure 6 The description in the text will not be repeated here.

[0044] Step S520: Based on the changes in each pixel unit before and after stretching, determine the compensation data for each pixel unit.

[0045] In this embodiment, the compensation data for each pixel unit is determined by calculating the change in displacement of each pixel unit before and after stretching. The change in displacement of a pixel unit before and after stretching is the displacement change. For example, for each pixel unit, the displacement change of the pixel unit before and after stretching is determined, and then, based on the displacement change of the pixel unit before and after stretching, the displacement amount that the pixel unit needs to compensate for is determined as the compensation data for the pixel unit.

[0046] Step S530: Correct the image based on the compensation data of each of the multiple pixel units.

[0047] In this embodiment, the data signal is compensated based on the compensation data of each of the multiple pixel units; the image is then corrected based on the compensated data signal. For example, after stretching, the pixel units deform; without correction, the image will also be distorted. In this embodiment, compensating the data signal and then correcting the image with the compensated data signal can reduce or avoid image distortion and improve the display effect.

[0048] Figure 6 This is a flowchart illustrating the process of determining the change in a pixel unit before and after stretching, according to an embodiment of this application. Figure 6 As shown, the method includes the following steps.

[0049] Step S610: Obtain the first position of each of the multiple detection units corresponding to the multiple pixel units before stretching.

[0050] In this embodiment of the application, before stretching, for each pixel unit, the multiple detection units corresponding to the pixel unit detect their respective first positions, and the first positions of the detection units can reflect the position information of the pixel unit before stretching.

[0051] Step S620: Obtain the second position of each of the multiple detection units corresponding to the multiple pixel units after stretching.

[0052] In the embodiments of this application, after stretching, for each pixel unit, the multiple detection units corresponding to the pixel unit detect their respective second positions, and the second positions of the detection units can reflect the position information of the pixel unit after stretching.

[0053] Step S630: Based on the first position of each of the multiple detection units corresponding to each of the multiple pixel units before stretching and the second position of each of the multiple detection units corresponding to each of the multiple pixel units after stretching, determine the amount of change of each of the multiple pixel units before and after stretching.

[0054] In this embodiment, for each pixel unit, the change in the pixel unit before and after stretching is determined based on the first position before stretching and the second position after stretching of the multiple detection units corresponding to that pixel unit. The change in the pixel unit before and after stretching includes both stretching and rotation. In this embodiment, the number of detection units is greater than or equal to two, thus allowing for the simultaneous determination of both stretching and rotation of the pixel unit. Specifically, the stretching and rotation of the pixel unit are determined by calculation and conversion using the first position before stretching and the second position after stretching of the multiple detection units.

[0055] This application also provides an image correction device suitable for the aforementioned stretchable display panel. Exemplarily, Figure 7 This is a structural block diagram of an image correction device provided in an embodiment of this application. For example... Figure 7 As shown, the image correction device includes an acquisition module 710, a determination module 720, and a correction module 730.

[0056] The acquisition module 710 is used to acquire the changes in each of the multiple pixel units on the stretchable display panel before and after stretching.

[0057] In this embodiment, the stretchable display panel is the same as the stretchable display panel described in the above embodiments. The changes in a pixel unit before and after stretching include both stretching and rotation. These changes can be determined using multiple detection units (e.g., displacement sensors). For example, if there are two detection units, the positional changes of these two units can reflect both stretching and rotation of the pixel unit. If there are more than two detection units (e.g., four), the positional changes of these four detection units can reflect both stretching and rotation of the pixel unit, and the detection results can be cross-checked to further improve detection accuracy.

[0058] Optionally, the acquisition module 710 is further configured to acquire the first positions of each of the multiple detection units corresponding to each of the multiple pixel units before stretching. In this embodiment, before stretching, for each pixel unit, the multiple detection units corresponding to that pixel unit detect their respective first positions, and the first positions of the detection units can reflect the position information of the pixel unit before stretching.

[0059] Optionally, the acquisition module 710 is further configured to acquire the stretched second positions of the multiple detection units corresponding to each of the multiple pixel units. In this embodiment, after stretching, for each pixel unit, the multiple detection units corresponding to that pixel unit detect their respective second positions, and the second positions of the detection units can reflect the position information of the pixel unit after stretching.

[0060] Optionally, the acquisition module 710 is further configured to determine the amount of change of each of the multiple pixel units before and after stretching based on the first position of each of the multiple detection units corresponding to each of the multiple pixel units before stretching and the second position of each of the multiple detection units corresponding to each of the multiple pixel units after stretching. In this embodiment, for each pixel unit, the amount of change of the pixel unit before and after stretching is determined according to the first position of the multiple detection units corresponding to that pixel unit before stretching and the second position of the multiple detection units after stretching. The amount of change of the pixel unit before and after stretching includes stretching change and rotation change. In this embodiment, the number of detection units is greater than or equal to two, thus, the stretching change and rotation change of the pixel unit can be determined simultaneously. Specifically, the stretching change and rotation change of the pixel unit are determined by calculation and conversion using the first position of the multiple detection units before stretching and the second position of the multiple detection units after stretching.

[0061] The determination module 720 is used to determine the compensation data of each of the multiple pixel units based on the amount of change of each pixel unit before and after stretching.

[0062] In this embodiment, the compensation data for each pixel unit is determined by calculating the change in displacement of each pixel unit before and after stretching. The change in displacement of a pixel unit before and after stretching is the displacement change. For example, for each pixel unit, the displacement change of the pixel unit before and after stretching is determined, and then, based on the displacement change of the pixel unit before and after stretching, the displacement amount that the pixel unit needs to compensate for is determined as the compensation data for the pixel unit.

[0063] The correction module 730 is used to correct the image based on the compensation data of each of the multiple pixel units.

[0064] Optionally, the correction module 730 is further configured to compensate the data signal based on the compensation data of each of the multiple pixel units; and to correct the image based on the compensated data signal. For example, after stretching, the pixel units deform; if no correction is performed, the image will also be deformed. In this embodiment, compensating the data signal and then correcting the image with the compensated data signal can reduce or avoid image deformation and improve the display effect.

[0065] The specific working principle and benefits of the image correction device provided in this application embodiment are similar to those of the image correction method provided in this application embodiment, and will not be repeated here.
