Description

Technical Field

[0001] This application relates to the field of display panels, specifically to a liquid crystal display panel and an electronic device. Background Technology

[0002] With technological advancements, electronic devices equipped with liquid crystal display panels have become everyday necessities. However, liquid crystal display panels in this technology are prone to image sticking, resulting in poor display quality. Summary of the Invention

[0003] In a first aspect, embodiments of this application provide a liquid crystal display panel, including:

[0004] A first substrate, a first electrode layer, a first alignment film, and a first memory layer are sequentially stacked. The first alignment film includes a plurality of first alignment portions, and the first memory layer includes a plurality of first memory portions. The first memory portions are disposed on the first alignment portions.

[0005] A second substrate, a second electrode layer, and a second alignment film are sequentially stacked, with the second alignment film facing the first alignment film to form a receiving space. The first substrate is one of a TFT substrate and a CF substrate, and the second substrate is the other of a TFT substrate and a CF substrate.

[0006] A liquid crystal layer is disposed in the receiving space;

[0007] When the liquid crystal display panel displays a grayscale image, the first electrode layer and the second electrode layer are driven by a driving voltage. Different grayscale images correspond to different driving voltages, and the thickness of the first memory section is different under different grayscale driving voltages, so as to drive the liquid crystal in the liquid crystal layer near the first memory section to rotate to a first set angle, so that the grayscale of the image displayed by the liquid crystal display panel is consistent with the corresponding ideal grayscale.

[0008] In a second aspect, embodiments of this application provide an electronic device, the electronic device including a liquid crystal display panel as described in the first aspect.

[0009] In summary, the liquid crystal display panel provided in this application provides a first memory layer on the first alignment film. This first memory layer can deform under the action of a driving voltage, causing the thickness of the first memory portion to expand. By controlling the magnitude of the driving voltage, the liquid crystal in the liquid crystal layer expands to a first predetermined angle corresponding to the grayscale of the image to be displayed on the liquid crystal display panel. Therefore, the grayscale displayed by the liquid crystal display panel is consistent with the ideal grayscale. When the liquid crystal display panel switches between different images, the problem of image retention can be reduced or even avoided. Thus, the liquid crystal display panel provided in this application has superior display quality. Attached Figure Description

[0036] 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 of ordinary skill in the art without creative effort are within the scope of protection of this application.

Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0039] Before introducing the liquid crystal display panel 10 provided in the embodiments of this application, the liquid crystal display panel 10 in the related art will be introduced first.

[0040] Please see Figure 1 and Figure 2 , Figure 1 A schematic diagram of a black and white chessboard displayed on a liquid crystal display panel in related technologies; Figure 2 This refers to the image displayed when the liquid crystal display panel in the related technology switches to a screen with the same grayscale. Figure 1 As can be seen, in the related technology, when the liquid crystal display panel 10 displays a black and white checkerboard pattern, some areas are displayed as black and some areas as white, with the white areas and the black areas alternated. When the liquid crystal display panel 10 displays... Figure 1In the example shown, after a period of time, when attempting to switch to a display with uniform grayscale across the entire screen, the areas that originally displayed white on the liquid crystal display panel 10 exhibit a brighter grayscale, while the areas that originally displayed black on the liquid crystal display panel 10 exhibit a darker grayscale, failing to achieve a uniform grayscale display effect. Therefore, it is evident that when a display panel in the related technology displays the same static image for a period of time before switching to a different display, the previous image is retained after the display content is changed. This phenomenon is called image sticking or AC image retention. Generally, image sticking occurs in in-plane switching (IPS) type liquid crystal display panels 10 using thin film transistor array (TFT) substrate technology. Understandably, image sticking also occurs in liquid crystal display panels 10 using the twisted nematic (TN) mode in the related technology.

[0041] The principle of image retention in related technologies is explained as follows.

[0042] Please continue reading. Figure 3 , Figure 3 This is a schematic diagram of the image retention principle of a liquid crystal display panel in related technologies. Figure 3 (a) in the figure shows the display phenomenon of the liquid crystal display panel 10 when no signal is loaded, and (a)' is the liquid crystal arrangement diagram corresponding to (a).

[0043] Figure 3 (b) in the diagram shows the display phenomenon when the liquid crystal display panel 10 displays a black and white checkerboard pattern, and (b)' is a schematic diagram of the liquid crystal arrangement corresponding to (b). Figure 3 In diagram (c), the display phenomenon occurs when the liquid crystal display panel 10 switches to a uniform grayscale image, and (c)' is a schematic diagram of the liquid crystal arrangement corresponding to (c). Figure 3 As can be seen from (a) and (a)', when the liquid crystal display panel 10 does not record a signal, the displayed image is completely black, and the liquid crystal does not rotate. Figure 3As can be seen from (b) and (b)', when the liquid crystal display panel 10 displays a black and white checkerboard pattern, the liquid crystals corresponding to the white checkerboard areas rotate, while the liquid crystals corresponding to the black checkerboard areas do not rotate. When the liquid crystals rotate, they are subjected to the force of the external electric field in the liquid crystal display panel 10 and the intermolecular forces of the alignment film (such as PI) on the liquid crystal molecules. The liquid crystal molecules on the surface of the alignment film are subjected to a greater force from the molecules in the alignment film (such as PI molecules) than the force of the external electric field, so the surface liquid crystal molecules do not rotate or rotate below the theoretical value. The closer the liquid crystal molecules are to the middle layer, the greater the force of the external electric field, resulting in a larger rotation and a closer relationship to the theoretical value. When the signal is continuously output, the liquid crystals in the white checkerboard areas affect the liquid crystals on the surface of the alignment film (such as PI) through intermolecular forces (electrical forces and dispersion forces). If the alignment ability of the alignment film is poor, the pretilt angle of the liquid crystals on the surface of the alignment film changes with the rotation of the liquid crystals. Figure 3 As can be seen in (b), the pretilt angle of the liquid crystal in the white grid area of ​​the liquid crystal display panel 10 has deflected compared to the pretilt angle of the liquid crystal in the black grid area of ​​the liquid crystal display panel 10.

[0044] Depend on Figure 3 As can be seen from (c) and (c)', when the liquid crystal display panel 10 switches to a uniform grayscale image, the same grayscale voltage is applied to all parts of the liquid crystal display panel 10. Theoretically, the liquid crystal display panel 10 displays a uniform grayscale image. However, from the previous... Figure 3 As described in (b), the pretilt angle of the liquid crystal in the white grid area of ​​the liquid crystal display panel 10 has been deflected compared to the pretilt angle of the liquid crystal in the black grid area. Therefore, when the same grayscale voltage is applied to all parts of the display panel, the liquid crystal in the area where the angle has been deflected is more likely to be deflected to the theoretical value, while the liquid crystal in the area where the angle has not been deflected is less likely to be deflected to the theoretical value. In other words, the liquid crystal in the white grid area where the pretilt angle has been deflected is more likely to be deflected to the theoretical angle value, resulting in higher transmittance; while the liquid crystal in the black grid area where the pretilt angle has not been deflected is less likely to be deflected to the theoretical value, resulting in lower transmittance, thus causing image retention.

[0045] It is evident that the liquid crystal display panel 10 in the related technology is prone to image retention.

[0046] The liquid crystal display panel 10 provided in the embodiments of this application will now be described.

[0047] The liquid crystal display panel 10 can be an in-plane switching (IPS) type liquid crystal display panel 10, or a twisted nematic (TN) type liquid crystal display panel 10.

[0048] Please see Figure 4 and Figure 5 , Figure 4 This is a schematic diagram of the structure of a liquid crystal display panel provided in one embodiment of this application; Figure 5 One implementation method Figure 4 The diagram shows a partial cross-sectional view of a liquid crystal display panel along line II. The liquid crystal display panel 10 includes a first substrate 110, a first electrode layer 120, a first alignment film 130, and a first memory layer 140, which are sequentially stacked. The first alignment film 130 includes a plurality of first alignment portions 131. The first memory layer 140 includes a plurality of first memory portions 141, and the first memory portions 141 are disposed on the first alignment portions 131.

[0049] Furthermore, the liquid crystal display panel 10 also includes a second substrate 210, a second electrode layer 220, a second alignment film 230, and a liquid crystal layer 310, which are sequentially stacked. The second alignment film 230 is opposite to the first alignment film 130 to form a receiving space 10a. The first substrate 110 is one of a thin film transistor array (TFT) substrate and a color filter (CF) substrate, and the second substrate 210 is the other of a TFT substrate and a CF substrate. The liquid crystal layer 310 is disposed in the receiving space 10a.

[0050] When the liquid crystal display panel 10 displays a grayscale image, the first electrode layer 120 and the second electrode layer 220 are loaded with driving voltage. Different grayscale images correspond to different driving voltages, and the thickness of the first memory section 141 is different under different grayscale driving voltages, so as to drive the liquid crystal in the liquid crystal layer 310 near the first memory section 141 to rotate to a first set angle, so that the grayscale of the image displayed by the liquid crystal display panel 10 is consistent with the ideal grayscale under the corresponding driving voltage.

[0051] The first substrate 110 may be, but is not limited to, a light-transmitting substrate such as glass or plastic. The shape of the first substrate 110 may be, but is not limited to, a rectangle, a rectangular shape, a square shape, a circular shape, a circular shape, etc., and is not limited here.

[0052] The liquid crystal display panel 10 includes a first substrate 110, a first electrode layer 120, a first alignment film 130, and a first memory layer 140 stacked sequentially. Specifically, the first electrode layer 120 is disposed on one side of the first substrate 110, and the first alignment film 130 is disposed on the side of the first electrode layer 120 opposite to the first substrate 110. The first memory layer 140 is disposed on the side of the first alignment film 130 opposite to the first substrate 110. The first memory layer 140 is closer to the second substrate 210 than the first substrate 110.

[0053] The first alignment film 130 includes a plurality of first alignment portions 131. The first memory layer 140 includes a plurality of first memory portions 141, and the first memory portions 141 are disposed on the first alignment portions 131. One first memory portion 141 is disposed on one first alignment portion 131, and different first memory portions 141 are disposed on different first alignment portions 131.

[0054] The second substrate 210 can be, but is not limited to, a light-transmitting substrate such as glass or plastic. The shape of the second substrate 210 can be, but is not limited to, rectangular, rectangular, square, square, circular, or circular shapes; no limitation is made here. The material of the second substrate 210 can be the same as or different from that of the first substrate 110; no limitation is made here.

[0055] The liquid crystal display panel 10 further includes a second substrate 210, a second electrode layer 220, a second alignment film 230, and a liquid crystal layer 310, which are sequentially stacked. Specifically, the second substrate 210 is disposed opposite to and spaced apart from the first substrate. The second electrode layer 220 is disposed on the side of the second substrate 210 facing the first substrate 110. The second alignment film 230 is disposed on the side of the second electrode layer 220 away from the second substrate 210. The liquid crystal layer 310 is disposed within the receiving space 10a. The second alignment film 230 and the first alignment film 130 are used to guide the orderly alignment of the liquid crystal in the liquid crystal layer 310.

[0056] In this embodiment, the first substrate 110 is a TFT substrate and the second substrate 210 is a CF substrate, as an example. Accordingly, the first electrode layer 120 is a pixel electrode layer, and the second electrode layer 220 is a common electrode layer. In other embodiments, the first substrate 110 is a CF substrate, and the second substrate 210 is a TFT substrate. Accordingly, the first electrode layer 120 is a common electrode layer, and the second electrode layer 220 is a pixel electrode layer.

[0057] Typically, the pixel electrode layer comprises multiple pixel electrodes arranged in an array, while the common electrode layer is usually a single, solid electrode. A pixel voltage is applied to the pixel electrodes, and a common voltage is typically applied to the common electrode layer. The voltages applied to the pixel electrodes and the common electrode layer are collectively referred to as driving voltages. These driving voltages are used to drive the liquid crystal in the liquid crystal layer 310 to rotate, causing the display panel to display an image. When the driving voltage drives the liquid crystal in the liquid crystal layer 310 to rotate at different angles, the grayscale of the image displayed on the liquid crystal display panel 10 differs; therefore, the driving voltage is also called grayscale voltage.

[0058] In one embodiment, the material of the first memory unit 141 is a shape memory polymer (SMP). The main substrate is a polymer material, including polyurethane, polyester, polyamide, copolyester, polyisoprene, polyethylene, etc. It changes shape accordingly under external stimuli (such as temperature and voltage) (having a deformation function), and after the stimulus is removed, its deformed state can be fixed (having a shaping function). If the external environment changes again in a specific way and according to a certain pattern, it can reversibly return to its initial state (having a recovery function). According to the form and shape of the material, there are shape memory polymer solutions, shape memory polymer powders, shape memory polymer granules, shape memory polymer wires, shape memory polymer foams, shape memory polymer films, etc.

[0059] In one embodiment, the first memory section 141 provided in this application selects a shape memory polymer film as the expansion material. The expansion material can be, but is not limited to, a shape memory polymer film. For example, a shape memory polyurethane composite. Shape memory polyurethane composites can be compounded with various resins to obtain good overall performance, possessing good mechanical and processing properties, adapting to different application needs, maintaining good shape memory performance, having low cost, and a wide range of applications, meeting the needs of injection molding, extrusion, film formation, and other application scenarios.

[0060] In one embodiment, the first memory portion 141 is disposed inside the alignment axis of the first alignment portion 131. The first memory portion 141 can deform under the action of the driving voltage. Specifically, the first memory portion 141 expands differently depending on the driving voltage, resulting in different thicknesses. A higher driving voltage leads to greater volume expansion and thickness of the first memory portion 141; conversely, a lower driving voltage results in less volume expansion and thickness. In one embodiment, the material of the first memory portion 141 has a certain coefficient of thermal expansion. Different driving voltages at different grayscale levels cause different expansions in the first memory portion 141, resulting in different thicknesses. When the liquid crystal display panel 10 displays a grayscale image, the first electrode layer 120 and the second electrode layer 220 are loaded with driving voltages. Different grayscale images correspond to different grayscale voltages. The thickness of the first memory section 141 varies under different grayscale driving voltages. Generally, the larger the grayscale, the higher the driving voltage, and the thicker the first memory section 141; correspondingly, the smaller the grayscale, the lower the driving voltage, and the thinner the first memory section 141. When the liquid crystal display panel 10 displays a grayscale image, the first electrode layer 120 and the second electrode layer 220 are subjected to driving voltages, causing the thickness of the first memory section 141 to change, and causing the liquid crystal in the liquid crystal layer 310 near the first memory section 141 to rotate to a first predetermined angle. Different driving voltages for different grayscales result in different thicknesses of the first memory section 141, which in turn causes the first predetermined angle of rotation of the liquid crystal in the liquid crystal layer 310 near the first memory section 141 to vary. The liquid crystal in the liquid crystal display panel 10 rotates to the first predetermined angle under the action of the first memory section 141, and the liquid crystal in the liquid crystal layer 310 rotates under the drive voltage. The effect of the first memory unit 141 on the liquid crystal in the liquid crystal layer 310, and the rotation of the liquid crystal in the liquid crystal layer 310 caused by the driving voltage, work together to make the grayscale of the image displayed on the display panel consistent with the ideal grayscale.

[0061] Even after the liquid crystal display panel 10 displays the current grayscale image for a period of time and then switches to the next grayscale image, as described above, the driving voltage acts on the first memory unit 141. This causes the first memory unit 141 to act on the liquid crystal in the liquid crystal layer 310, and the driving voltage causes the liquid crystal in the liquid crystal layer 310 to rotate. Together, these actions ensure that the grayscale of the next grayscale image displayed by the display panel is consistent with the ideal grayscale. Therefore, image retention can be reduced or even avoided when the liquid crystal display panel 10 displays an image.

[0062] Furthermore, when the driving voltage is removed (also considered as when the grayscale voltage is 0), the liquid crystal in the liquid crystal layer 310 will quickly return to its initial state before the driving voltage was applied. Specifically, when the driving voltage is removed, the first alignment film 130, through intermolecular forces, causes the liquid crystal in the liquid crystal layer 310 at the first alignment film 130 to recover, preventing the liquid crystal from failing to recover for an extended period. Similarly, the second alignment film 230, through intermolecular forces, causes the liquid crystal in the liquid crystal layer 310 at the second alignment film 230 to recover, preventing the liquid crystal from failing to recover for an extended period.

[0063] In summary, the liquid crystal display panel 10 provided in this application provides a first memory layer 140 on the first alignment film 130. This first memory layer 140 can deform under the action of a driving voltage, causing the first memory portion 141 to expand and change thickness. By controlling the magnitude of the driving voltage, the liquid crystal in the liquid crystal layer 310 expands to a first set angle corresponding to the grayscale of the image to be displayed by the liquid crystal display panel 10. Therefore, the grayscale displayed by the liquid crystal display panel 10 is consistent with the ideal grayscale. When the liquid crystal display panel 10 switches between different images, the problem of image retention can be reduced or even avoided. Therefore, the liquid crystal display panel 10 provided in this application has superior display quality.

[0064] Please refer to the following: Figure 6 and Figure 7 , Figure 6 for Figure 5 The diagram shows the liquid crystal deflection of the liquid crystal layer when the liquid crystal display panel displays a black screen. Figure 7 for Figure 5 The diagram illustrates the liquid crystal deflection of the liquid crystal layer when the liquid crystal display panel displays a white image. In this embodiment, the liquid crystal display panel 10 displaying a grayscale image of L0 to L255 is used as an example for illustration and explanation. Figure 6 In this configuration, the liquid crystal display panel 10 displays an L0 grayscale image, where the L0 grayscale image is a black state. At this time, the driving voltage is the driving voltage corresponding to the L0 grayscale, referred to as the L0 grayscale voltage or L0 voltage. At this time, the first memory unit 141 is in a normal state, i.e., a non-expanded state. At this time, the thickness of the first memory unit 141 is the first thickness.

[0065] exist Figure 7In this configuration, the liquid crystal display panel 10 displays an L255 grayscale image, where the L255 grayscale image is a white state image. At this time, the driving voltage is the driving voltage corresponding to L255, referred to as the L255 grayscale voltage or L255 voltage. At this time, the first memory section 141 is in an expanded state. At this time, the thickness of the first memory section 141 is a second thickness, where the second thickness is greater than the first thickness. At this time, the first memory section 141 causes the liquid crystal in the liquid crystal layer 310 near the first alignment film 130 to rotate to a first set angle; when the L255 grayscale voltage is removed, through intermolecular forces, the first memory section 141 causes the liquid crystal in the liquid crystal layer 310 to return to the first thickness.

[0066] Please see Figure 8 , Figure 8 This is a schematic diagram showing the thickness of the first memory section in a liquid crystal display panel provided according to an embodiment of this application. Figure 8 (a) is a schematic diagram of the thickness of the first memory section 141 when no driving voltage is applied to the first electrode layer 120 and the second electrode layer 220; Figure 8 (b) in the diagram shows the thickness of the first memory section 141 when the driving voltage applied to the first electrode layer 120 and the second electrode layer 220 is at its maximum. When no driving voltage is applied to the first electrode layer 120 and the second electrode layer 220, it can be considered that the voltage applied to the first electrode layer 120 and the second electrode layer 220 is zero. In this case, the image displayed by the liquid crystal display panel 10 is a black screen. When the driving voltage applied to the first electrode layer 120 and the second electrode layer 220 is the maximum driving voltage, that is, the maximum driving voltage required for the liquid crystal display panel 10 to display an image. For example, when the liquid crystal display panel 10 displays an image with gray levels L0 to L255, then the maximum driving voltage is the driving voltage for gray level L255 (i.e., a white screen).

[0067] When no driving voltage is applied to the first electrode layer 120 and the second electrode layer 220, the thickness d1 of the first memory section 141 satisfies: 7nm ≤ d1 ≤ 13nm (see...). Figure 8 (a)). When the driving voltage applied to the first electrode layer 120 and the second electrode layer 220 is the maximum driving voltage, the thickness d2 of the first memory section 141 satisfies: 32nm ≤ d2 ≤ 38nm (see (a)). Figure 8 (b) in the middle.

[0068] When no driving voltage is applied to the first electrode layer 120 and the second electrode layer 220, the thickness d1 of the first memory section 141 can be, but is not limited to, 7nm, 8nm, 9nm, 10nm, 11nm, 12nm, or 13nm.

[0069] When the driving voltage applied to the first electrode layer 120 and the second electrode layer 220 is the maximum driving voltage, the thickness d2 of the first memory section 141 can be, but is not limited to, 32nm, 33nm, 34nm, 35nm, 36nm, 37nm, or 38nm.

[0070] The liquid crystal display panel 10 provided in this application, by configuring the characteristics of the first memory section 141, satisfies the following conditions: when no driving voltage is applied to the first electrode layer 120 and the second electrode layer 220, the thickness d1 of the first memory section 141 satisfies: 7nm ≤ d1 ≤ 13nm; when the driving voltage applied to the first electrode layer 120 and the second electrode layer 220 is the maximum driving voltage, the thickness d2 of the first memory section 141 satisfies: 32nm ≤ d2 ≤ 38nm. Therefore, when the liquid crystal display panel 10 displays a grayscale image, the thickness of the first memory section 141 can change under the action of the driving voltage, thereby driving the liquid crystal in the liquid crystal layer 310 near the first memory section 141 to rotate to a first set angle, so that the grayscale of the image displayed by the liquid crystal display panel 10 is consistent with the corresponding ideal grayscale. Thus, image retention when the liquid crystal display panel 10 displays an image can be reduced or even avoided.

[0071] Please see Figure 9 , Figure 9 for Figure 5 A partial structural diagram of the liquid crystal display panel in the image. Figure 9 (a) in the middle is Figure 5 A partial structural diagram of the liquid crystal display panel in the image; Figure 9 (b) in the middle is Figure 5 Enlarged view at point II. The first alignment portion 131 has a first surface 131a for supporting the first memory portion 141, and the first surface 131a is inclined relative to the first substrate 110. The first surface 131a has a first region 1311 and a second region 1312, and the second region 1312 is further away from the first substrate 110 than the first region 1311. The first memory portion 141 is at least disposed in the first region 1311 and avoids the second region 1312.

[0072] In this embodiment, the second region 1312 is farther away from the first substrate 110 than the first region 1311. Therefore, the first region 1311 is the region adjacent to the first substrate 110, and the second region 1312 is the region away from the first substrate 110. In the schematic diagram of this embodiment, the first memory unit 141 is disposed in the first region 1311, and the first memory unit 141 is also disposed in the region between the first region 1311 and the second region 1312.

[0073] Since the first region 1311 is closer to the first substrate 110, the first memory portion 141 is at least disposed in the first region 1311. When the thickness of the first memory portion 141 located in the first region 1311 changes, the liquid crystal in the liquid crystal layer 310 adjacent to the first memory portion 141 can be squeezed better, thereby better driving the liquid crystal in the liquid crystal layer 310 adjacent to the first memory portion 141 to rotate to the first set angle at the corresponding gray level.

[0074] Furthermore, by avoiding the second region 1312, the first memory section 141 can reduce or even avoid the effect of the first memory section 141 on the liquid crystal corresponding to other adjacent first memory sections 141, thereby enabling the liquid crystal display panel 10 to have a better display effect when displaying.

[0075] Furthermore, since the surface of the first substrate 110 facing away from the first electrode layer 120 is typically planar or nearly planar, when the liquid crystal display panel 10 is manufactured, the surface of the first substrate 110 facing away from the first electrode layer 120 is usually placed on a carrier. Because the first surface 131a of the first alignment portion 131 of the first alignment layer is inclined relative to the first substrate 110, when the first memory layer 140 is manufactured on the first alignment layer, an expansion material layer for forming the first memory layer 140 is provided on the first alignment layer. This expansion material layer remains on the first memory portion 141 of the first memory layer 140, and the expansion material remaining on the first memory portion 141 slides down under the influence of gravity, thereby exposing the second region 1312 of the first memory portion 141. Therefore, the fact that the first memory portion 141 is at least located in the first region 1311 and avoids the second region 1312 is related to the manufacturing process of the first memory portion 141, facilitating the manufacture of the liquid crystal display panel 10.

[0076] Please continue reading. Figure 9 (b) and (c) in the text, Figure 9(c) is a schematic diagram showing the dimensions of the second region 1312 along the extension direction D of the first surface 131a. The dimension L1 of the second region 1312 along the extension direction D of the first surface 131a satisfies: 0 < L1 ≤ L2 / 10, where L2 is the dimension of the first surface 131a along the extension direction D.

[0077] The dimension L1 can be, but is not limited to, L2 / 50, L2 / 40, L2 / 30, L2 / 20, or L2 / 10. The dimension L1 of the second region 1312 extending along the first surface 131a satisfies: 0 < L1 ≤ L2 / 10. This further reduces or even avoids the effect of the first memory unit 141 on the liquid crystal corresponding to other adjacent first memory units 141, thereby enabling the liquid crystal display panel 10 to have a better display effect.

[0078] Please see Figure 9 and Figure 10 , Figure 10 for Figure 9 A schematic diagram of the dimensions of the first memory unit 141. The first memory unit 141 has a first end 1411 and a second end 1412 disposed opposite to each other. The first end 1411 is disposed corresponding to the first region 1311, and the second end 1412 is disposed adjacent to the second region 1312. The thickness D1 of the first end 1411 and the thickness D2 of the second end 1412 satisfy: 1≤D1 / D2≤1.1.

[0079] The ratio D1 / D2 of the thickness D1 of the first end 1411 and the thickness D2 of the second end 1412 can be, but is not limited to, 1, 1.03, 1.05, 1.08, or 1.1.

[0080] In one embodiment, the thickness of the first end 1411 is equal to the thickness of the second end 1412, that is, the ratio D1 / D2 of the thickness D1 of the first end 1411 and the thickness D2 of the second end 1412 can be, but is not limited to, 1.

[0081] In another embodiment, the thickness of the first end 1411 is greater than the thickness of the second end 1412, that is, the ratio of the thickness D1 of the first end 1411 to the thickness D2 of the second end 1412, D1 / D2, is greater than 1. When the thickness of the first end 1411 is greater than the thickness of the second end 1412, under the same driving voltage, the thickness change of the first end 1411 is greater than the thickness change of the second end 1412. The first end 1411 of the first memory section 141 can better squeeze the liquid crystal adjacent to the first memory section 141 in the liquid crystal layer 310, thereby driving the liquid crystal near the first memory section 141 in the liquid crystal layer 310 to rotate to a first set angle at the corresponding gray level.

[0082] Furthermore, the thickness D1 of the first end 1411 and the thickness D2 of the second end 1412 satisfy: 1≤D1 / D2≤1.1. On the one hand, this can reduce or even prevent the liquid crystal near the first memory section 141 in the liquid crystal layer 310 from rotating to the first set angle at the corresponding gray level due to the first memory section 141. On the other hand, it can reduce or even prevent the liquid crystal near the first memory section 141 in the liquid crystal layer 310 from rotating beyond the first set angle at the corresponding gray level due to the first memory section 141. In summary, the thickness D1 of the first end 1411 and the thickness D2 of the second end 1412 satisfy: 1≤D1 / D2≤1.1, which allows the first end 1411 of the first memory section 141 to better compress the liquid crystal near the first memory section 141 in the liquid crystal layer 310, thereby causing the liquid crystal near the first memory section 141 in the liquid crystal layer 310 to rotate to the first set angle at the corresponding gray level.

[0083] Please refer to the following: Figure 4 and Figure 11 , Figure 11 One implementation method Figure 4 A cross-sectional view of the liquid crystal display panel along line II is shown in the figure. In this embodiment, the liquid crystal display panel 10 further includes a second memory layer 240. The second memory layer 240 includes a plurality of second memory portions 241, which are disposed on the second alignment portion 231 and are located away from the second substrate 210 relative to the second alignment portion 231. When the liquid crystal display panel 10 displays a grayscale image, the thickness of the second memory portion 241 is different under different grayscale driving voltages, so as to drive the liquid crystal in the liquid crystal layer 310 near the second memory portion 241 to rotate to a second set angle. The second memory portion 241 cooperates with the first memory portion 141 so that the grayscale of the image displayed by the liquid crystal display panel 10 is consistent with the corresponding ideal grayscale.

[0084] The display panel also includes a second memory layer 240 which can be incorporated into the liquid crystal display panel 10 provided in any of the preceding embodiments.

[0085] The material of the second memory unit 241 is shape memory polymer (SMP). The main substrate is a polymer material, including polyurethane, polyester, polyamide, copolyester, polyisoprene, and polyethylene. It changes shape accordingly under external stimuli (such as temperature and voltage) (having deformation function), and can fix its deformed state after the stimulus is removed (having shape retention function). If the external environment changes again in a specific way and according to a certain pattern, it can reversibly return to its initial state (having recovery function). According to the form and shape of the material, there are shape memory polymer solutions, shape memory polymer powders, shape memory polymer granules, shape memory polymer wires, shape memory polymer foams, and shape memory polymer films, etc.

[0086] In one embodiment, the first memory section 141 provided in this application selects a shape memory polymer film as the expansion material. The expansion material can be, but is not limited to, a shape memory polymer film. For example, a shape memory polyurethane composite. Shape memory polyurethane composites can be compounded with various resins to obtain good overall performance, possessing good mechanical and processing properties, adapting to different application needs, maintaining good shape memory performance, having low cost, and a wide range of applications, meeting the needs of injection molding, extrusion, film formation, and other application scenarios.

[0087] In one embodiment, the second memory portion 241 is disposed inside the alignment axis of the second alignment portion 231. The second memory portion 241 can deform under the action of the driving voltage. Specifically, the second memory portion 241 expands differently depending on the driving voltage, resulting in different thicknesses. A higher driving voltage leads to greater volume expansion and thickness of the second memory portion 241; conversely, a lower driving voltage results in less volume expansion and thickness. In one embodiment, the material of the second memory portion 241 has a certain coefficient of thermal expansion. Different driving voltages at different gray levels cause different expansions in the second memory portion 241, resulting in different thicknesses. When the liquid crystal display panel 10 displays a grayscale image, the first electrode layer 120 and the second electrode layer 220 are loaded with driving voltages. Different grayscale images correspond to different grayscale voltages. The thickness of the second memory section 241 varies under different grayscale driving voltages. Generally, the larger the grayscale, the higher the driving voltage, and the thicker the second memory section 241; correspondingly, the smaller the grayscale, the lower the driving voltage, and the thinner the second memory section 241. When the liquid crystal display panel 10 displays a grayscale image, the first electrode layer 120 and the second electrode layer 220 are subjected to driving voltages, causing the thickness of the second memory section 241 to change, and causing the liquid crystal in the liquid crystal layer 310 near the second memory section 241 to rotate to a second predetermined angle. Different driving voltages for different grayscales result in different thicknesses of the second memory section 241, which in turn causes the second predetermined angle of rotation of the liquid crystal in the liquid crystal layer 310 near the second memory section 241 to be different. The liquid crystal in the liquid crystal display panel 10 rotates to the second predetermined angle under the action of the second memory section 241, and the liquid crystal in the liquid crystal layer 310 rotates under the drive voltage. The second memory unit 241 acts on the liquid crystal in the liquid crystal layer 310, and the driving voltage causes the liquid crystal in the liquid crystal layer 310 to rotate, together ensuring that the grayscale of the image displayed on the display panel matches the ideal grayscale. In this embodiment, the second memory unit 241 cooperates with the first memory unit 141 to ensure that the grayscale of the image displayed on the liquid crystal display panel 10 matches the corresponding ideal grayscale.

[0088] Even after the liquid crystal display panel 10 displays the current grayscale image for a period of time and then switches to the next grayscale image, as described above, the driving voltage acts on the second memory unit 241. This causes the second memory unit 241 to act on the liquid crystal in the liquid crystal layer 310, and the driving voltage causes the liquid crystal in the liquid crystal layer 310 to rotate. Together, these actions ensure that the grayscale of the next grayscale image displayed by the display panel is consistent with the ideal grayscale. Therefore, image retention can be reduced or even avoided when the liquid crystal display panel 10 displays an image.

[0089] Furthermore, when the driving voltage is removed (also considered as when the grayscale voltage is 0), the liquid crystal in the liquid crystal layer 310 will quickly return to its initial state before the driving voltage was applied. Specifically, when the driving voltage is removed, the second alignment film 230, through intermolecular forces, drives the liquid crystal in the liquid crystal layer 310 at the second alignment film 230 to recover, preventing the liquid crystal from failing to recover for an extended period.

[0090] In summary, the liquid crystal display panel 10 provided in this application provides a second memory layer 240 on the second alignment film 230. This second memory layer 240 can deform under the action of a driving voltage, causing the second memory portion 241 to expand and change thickness. By controlling the magnitude of the driving voltage, the liquid crystal in the liquid crystal layer 310 expands to a second predetermined angle corresponding to the grayscale of the image to be displayed by the liquid crystal display panel 10. Therefore, the grayscale displayed by the liquid crystal display panel 10 is consistent with the ideal grayscale. When the liquid crystal display panel 10 switches between different images, the problem of image retention can be reduced or even avoided. Thus, the liquid crystal display panel 10 provided in this application has superior display quality.

[0091] Furthermore, in this embodiment, the second memory unit 241 cooperates with the first memory unit 141 to further make the grayscale displayed by the liquid crystal display panel 10 consistent with the ideal grayscale. Moreover, the cooperation between the second memory unit 241 and the first memory unit 141 makes the liquid crystal driving in the liquid crystal layer 310 more sensitive, enabling the grayscale displayed by the liquid crystal display panel 10 to become consistent with the ideal grayscale as quickly as possible, thereby improving the response speed of the liquid crystal display panel 10 when displaying the ideal grayscale.

[0092] Please see Figure 12 , Figure 12 for Figure 11 This is a schematic diagram showing the thickness of the second memory section in the liquid crystal display panel. Figure 12 (a) is a schematic diagram of the thickness of the second memory section 241 when the first electrode layer 120 and the second electrode layer 220 are not driven by a voltage. Figure 12 (b) in the diagram shows the thickness of the second memory unit 241 when the driving voltage applied to the first electrode layer 120 and the second electrode layer 220 is at its maximum. When no driving voltage is applied to the first electrode layer 120 and the second electrode layer 220, it can be considered that the voltage applied to the first electrode layer 120 and the second electrode layer 220 is zero. In this case, the image displayed by the liquid crystal display panel 10 is a black screen. When the driving voltage applied to the first electrode layer 120 and the second electrode layer 220 is the maximum driving voltage, that is, the maximum driving voltage required for the liquid crystal display panel 10 to display an image. For example, when the liquid crystal display panel 10 displays an image with gray levels L0 to L255, then the maximum driving voltage is the driving voltage for gray level L255 (i.e., a white screen).

[0093] When no driving voltage is applied to the first electrode layer 120 and the second electrode layer 220, the thickness d3 of the second memory section 241 satisfies: 7nm ≤ d3 ≤ 13nm. When the driving voltage applied to the first electrode layer 120 and the second electrode layer 220 is the maximum driving voltage, the thickness d4 of the second memory section 241 satisfies: 32nm ≤ d4 ≤ 38nm.

[0094] When no driving voltage is applied to the first electrode layer 120 and the second electrode layer 220, the thickness d3 of the second memory section 241 can be, but is not limited to, 7nm, 8nm, 9nm, 10nm, 11nm, 12nm, or 13nm.

[0095] When the driving voltage applied to the first electrode layer 120 and the second electrode layer 220 is the maximum driving voltage, the thickness d4 of the second memory section 241 can be, but is not limited to, 32nm, 33nm, 34nm, 35nm, 36nm, 37nm, or 38nm.

[0096] The liquid crystal display panel 10 provided in this application, by configuring the characteristics of the second memory section 241, satisfies the following conditions: when no driving voltage is applied to the first electrode layer 120 and the second electrode layer 220, the thickness d3 of the second memory section 241 satisfies: 7nm ≤ d3 ≤ 13nm; when the driving voltage applied to the first electrode layer 120 and the second electrode layer 220 is the maximum driving voltage, the thickness d4 of the second memory section 241 satisfies: 32nm ≤ d4 ≤ 38nm. Therefore, when the liquid crystal display panel 10 displays a grayscale image, the thickness of the second memory section 241 can change under the action of the driving voltage, thereby causing the liquid crystal in the liquid crystal layer 310 near the second memory section 241 to rotate to a second set angle, so that the grayscale of the image displayed by the liquid crystal display panel 10 is consistent with the corresponding ideal grayscale. Thus, image retention when the liquid crystal display panel 10 displays an image can be reduced or even avoided.

[0097] Please see Figure 13 , Figure 13 for Figure 11 A partial structural diagram of the liquid crystal display panel in the image. Figure 13 (a) in the middle is Figure 11 A partial structural diagram of the liquid crystal display panel in the image; Figure 13 (b) in the middle is Figure 11 Enlarged schematic diagram at point III. The second alignment portion 231 has a second surface 231a for supporting the second memory portion 241, and the second surface 231a is inclined relative to the second substrate 210. The second surface 231a has a third region 2311 and a fourth region 2312, the fourth region 2312 being further away from the second substrate 210 than the third region 2311, and the second memory portion 241 is at least disposed in the third region 2311 and avoids the fourth region 2312.

[0098] In this embodiment, the fourth region 2312 is farther away from the second substrate 210 than the third region 2311. Therefore, the third region 2311 is the region adjacent to the second substrate 210, and the fourth region 2312 is the region away from the second substrate 210. In the schematic diagram of this embodiment, the second memory unit 241 is disposed in the third region 2311, and the second memory unit 241 is also disposed in the region between the third region 2311 and the fourth region 2312.

[0099] Since the third region 2311 is closer to the second substrate 210, the second memory portion 241 is at least disposed in the third region 2311. When the thickness of the second memory portion 241 located in the third region 2311 changes, the liquid crystal in the liquid crystal layer 310 adjacent to the second memory portion 241 can be squeezed better, thereby better driving the liquid crystal in the liquid crystal layer 310 adjacent to the second memory portion 241 to rotate to the second set angle at the corresponding gray level.

[0100] Furthermore, since the second memory section 241 avoids the fourth region 2312, the effect of the second memory section 241 on the liquid crystal corresponding to other adjacent second memory sections 241 can be reduced or even avoided, thereby enabling the liquid crystal display panel 10 to have a better display effect when displaying.

[0101] Furthermore, since the surface of the second substrate 210 facing away from the second electrode layer 220 is typically planar or nearly planar, when the liquid crystal display panel 10 is manufactured, the surface of the second substrate 210 facing away from the second electrode layer 220 is typically placed on a carrier. Because the second surface 231a of the second alignment portion 231 of the second alignment layer is inclined relative to the second substrate 210, when the second memory layer 240 is manufactured on the second alignment layer, an expansion material layer for forming the second memory layer 240 is provided on the second alignment layer. This expansion material layer remains on the second memory portion 241 of the second memory layer 240, and the expansion material remaining on the second memory portion 241 slides down under the influence of gravity, thereby exposing the fourth region 2312 of the second memory portion 241. Therefore, the fact that the second memory portion 241 is at least located in the third region 2311 and avoids the fourth region 2312 is related to the manufacturing process of the second memory portion 241, facilitating the manufacture of the liquid crystal display panel 10.

[0102] Please continue reading. Figure 13 (b) and (c) in the text, Figure 13 (c) is a schematic diagram of the dimensions of the fourth region 2312 in the extension direction D of the second surface 231a. The dimension L3 of the fourth region 2312 in the extension direction of the second surface 231a satisfies: 0 < L3 ≤ L4 / 10, where L4 is the dimension of the second surface 231a in the extension direction.

[0103] The dimension L3 can be, but is not limited to, L4 / 50, L4 / 40, L4 / 30, L4 / 20, or L4 / 10. The dimension L3 of the fourth region 2312 in the extension direction of the second surface 231a satisfies: 0 < L3 ≤ L4 / 10, which can further reduce or even avoid the effect of the second memory unit 241 on the liquid crystal corresponding to other adjacent second memory units 241, thereby enabling the liquid crystal display panel 10 to have a better display effect when displaying.

[0104] Please see Figure 13 and Figure 14 , Figure 14 for Figure 13 A schematic diagram of the dimensions of the second memory unit. The second memory unit 241 has a third end 2411 and a fourth end 2412 disposed opposite to each other, wherein the third end 2411 is disposed corresponding to the third region 2311, and the fourth end 2412 is disposed adjacent to the fourth region 2312, wherein the thickness D3 of the third end 2411 and the thickness D4 of the fourth end 2412 satisfy: 1≤D3 / D4≤1.1.

[0105] The ratio D3 / D4 of the thickness D3 of the third end 2411 and the thickness D4 of the fourth end 2412 can be, but is not limited to, 1, 1.03, 1.05, 1.08, or 1.1.

[0106] In one embodiment, the thickness of the third end 2411 is equal to the thickness of the fourth end 2412, that is, the ratio D3 / D4 of the thickness D3 of the third end 2411 and the thickness D4 of the fourth end 2412 can be, but is not limited to, 1.

[0107] In another embodiment, the thickness of the third end 2411 is greater than the thickness of the fourth end 2412, that is, the ratio of the thickness D3 of the third end 2411 to the thickness D4 of the fourth end 2412, D3 / D4, is greater than 1. When the thickness of the third end 2411 is greater than the thickness of the fourth end 2412, under the same driving voltage, the thickness change of the third end 2411 is greater than the thickness change of the fourth end 2412. The third end 2411 of the second memory section 241 can better compress the liquid crystal adjacent to the second memory section 241 in the liquid crystal layer 310, thereby driving the liquid crystal near the second memory section 241 in the liquid crystal layer 310 to rotate to a second set angle at the corresponding gray level.

[0108] Furthermore, the thickness D3 of the third end 2411 and the thickness D4 of the fourth end 2412 satisfy: 1≤D3 / D4≤1.1. On the one hand, this can reduce or even prevent the liquid crystal near the second memory section 241 in the liquid crystal layer 310 from rotating beyond the second set angle at the corresponding gray level caused by the second memory section 241. On the other hand, it can reduce or even prevent the liquid crystal near the second memory section 241 in the liquid crystal layer 310 from rotating beyond the second set angle at the corresponding gray level caused by the second memory section 241. In summary, the thickness D3 of the third end 2411 and the thickness D4 of the fourth end 2412 satisfy: 1≤D3 / D4≤1.1, which allows the third end 2411 of the second memory section 241 to better compress the liquid crystal adjacent to the second memory section 241 in the liquid crystal layer 310, thereby causing the liquid crystal near the second memory section 241 in the liquid crystal layer 310 to rotate to the second set angle at the corresponding gray level.

[0109] The following describes a method for manufacturing the liquid crystal display panel 10 according to one embodiment.

[0110] The fabrication method of the liquid crystal display panel 10 mainly includes the liquid crystal injection (ODF) step S10 in the liquid crystal display panel 10. That is, the fabrication method of the liquid crystal display panel 10 includes S10, liquid crystal injection (ODF). Please refer to [link to documentation]. Figure 15 , Figure 15 This is a schematic diagram of the ODF (Optical Distribution Function) process in the liquid crystal display panel fabrication method provided in one embodiment of this application. The ODF step S10 in the liquid crystal panel fabrication method includes S110, S120, and S130, which are described in detail below.

[0111] S110, a spacer is formed on at least one of the first substrate 110 or the second substrate 210.

[0112] The padding material can be applied via, but is not limited to, a spraying process. The cell thickness of the liquid crystal display panel 10 is typically determined by the diameter of the padding material. In other words, the liquid crystal display panel 10 manufacturing method provided in this application is achieved by selecting a predetermined diameter for the spherical padding material.

[0113] S120, frame material, conductive dot material and liquid crystal coating.

[0114] The frame material serves three purposes: 1. to bond the first substrate 110 and the second substrate 210 together; 2. to fix the cell thickness of the liquid crystal display panel 10; and 3. to confine the liquid crystal layer 310 within the cell formed by the first substrate 110 and the second substrate 210.

[0115] The conductive dots can be, but are not limited to, silver dots. The conductive dots provide the current transmission path required by the liquid crystal display panel 10, enabling the liquid crystal display panel 10 to operate. The conductive dots can be, but are not limited to, silver dots.

[0116] Liquid crystal coating is used to form a liquid crystal layer 310. Different rotation angles of the liquid crystal in the liquid crystal layer 310 can cause different light emitted from the liquid crystal display panel 10, thereby giving the liquid crystal display panel 10 different optical states. Therefore, the function of the liquid crystal is to change the optical state of the liquid crystal display panel 10 after cell assembly.

[0117] The liquid crystal coating method can be, but is not limited to, liquid crystal drop-on coating. Liquid crystal can be dropped onto the first substrate 110 or the geothermal substrate, and then the first substrate 110 and the second substrate 210 can be bonded together in a vacuum environment.

[0118] S130, the frame material, the conductive dot material and the liquid crystal are cured.

[0119] The curing of the frame material, the conductive dots, and the liquid crystal may include, but is not limited to, ultraviolet curing and thermal curing.

[0120] The following describes a method for fabricating a liquid crystal display panel 10 according to an embodiment of this application, using a fabricated liquid crystal display panel 10 comprising a first memory layer 140 and a second memory layer 240 as an example. Please refer to [link to relevant documentation]. Figure 16 , Figure 16 This is a schematic diagram illustrating the process steps included in the method for manufacturing a liquid crystal display panel according to an embodiment of this application. The method for manufacturing the liquid crystal display panel 10 according to an embodiment of this application includes steps S1, S2, S3, S4, S10, and S5. Steps S1, S2, S3, S4, and S5 will be described in detail below.

[0121] S1, a first alignment film 130 is disposed on a first substrate 110 on which a first electrode layer 120 is disposed, wherein the first alignment film 130 includes a plurality of first alignment portions 131.

[0122] In one embodiment, the first substrate 110 is a TFT substrate. First, a first electrode layer 120 is formed on the first substrate 110, and then an alignment material (such as PI) is coated on the surface of the first electrode layer 120 away from the first substrate 110 to form a first alignment film 130.

[0123] S2, a first memory layer 140 is formed on the surface of the first alignment film 130 opposite to the first substrate 110.

[0124] The first memory layer 140 can be formed, but is not limited to, by injecting an expansion material onto the surface of the first alignment film 130 away from the first substrate 110 and curing the expansion material to form the first memory layer 140.

[0125] S3, a second alignment film 230 is disposed on a second substrate 210 on which a second electrode layer 220 is disposed, wherein the second alignment film 230 includes a plurality of second alignment portions 231.

[0126] S4, a second memory layer 240 is formed on the surface of the second alignment film 230 opposite to the second substrate 210.

[0127] The second memory layer 240 can be formed, but is not limited to, by injecting an expansion material onto the surface of the second alignment film 230 away from the second substrate 210 and curing the expansion material to form the second memory layer 240.

[0129] S5, forming a cell to create the liquid crystal display panel 10.

[0130] Please see Figure 17 , Figure 17 This is a schematic diagram of an electronic device provided according to one embodiment of this application. The electronic device 11 includes, but is not limited to, devices with a liquid crystal display panel 10, such as mobile phones, telephones, televisions, tablets, cameras, personal computers, laptops (PCs), in-vehicle devices, headphones, watches, wearable devices, base stations, and vehicle radars. The electronic device 1 includes the liquid crystal display panel 10 as described in any of the preceding embodiments. Please refer to the preceding description of the liquid crystal display panel 10; it will not be repeated here.

[0131] Furthermore, in this embodiment, the electronic device 1 may also include a housing 20. The housing 20 is used to support the liquid crystal display panel 10. In addition, the housing 20 and the liquid crystal display panel 10 can together form an accommodating space to accommodate circuit boards, batteries, cameras, etc.
