[0029] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0030] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0031] With the advancement of technology, liquid crystal display (LCD) panels have become widely used in people's lives and production, and are widely applied in various portable electronic products, transportation vehicles, and more. Due to their low power consumption, high resolution, long lifespan, small footprint, and light weight, LCD panels are widely used in various devices requiring display capabilities. However, although display technology is relatively mature, some problems can still easily occur due to certain conditions. For example, in low-temperature environments, the liquid crystal material becomes viscous, resulting in a slow response time after power-on, which can easily cause ghosting when displaying dynamic images, leading to poor display quality, and in severe cases, even complete image display failure.

[0032] To address this, related technologies incorporate heating traces within the LCD panel to control its temperature within a reasonable range, ensuring liquid crystal flow and enabling normal operation. However, the display panel is prone to display abnormalities when the heating traces are in operation. The applicant's research has revealed that the heating traces typically achieve their heating effect by applying electricity. During this process, the heating traces generate an electric field, which can easily affect the normal deflection of the liquid crystal, thus leading to display abnormalities.

[0033] To solve the above problems, on the one hand, please refer to... Figure 1 This application provides a display panel including a substrate 10, a heating layer 20, a first electrode layer 30, a liquid crystal layer 40, and a shielding portion 50. The heating layer 20 is disposed on one side of the substrate 10 and includes heating traces 21. The first electrode layer 30 is disposed on the side of the heating layer 20 away from the substrate 10 and includes a plurality of first electrodes 31. Each first electrode 31 includes a body portion 311 and an edge located on at least one side of the body portion 311. At least a portion of the orthographic projection of the heating traces 21 onto the substrate 10 is adjacent to or overlaps with the orthographic projection of the edge portion 312 onto the substrate 10.

[0034] The liquid crystal layer 40 is disposed on the side of the first electrode layer 30 away from the substrate 10, and the first electrode 31 is used to drive the liquid crystal movement within the liquid crystal layer 40. The shielding portion 50 is disposed on the side of the heating layer 20 away from the substrate 10, and the orthographic projection of the shielding portion 50 on the substrate 10 is adjacent to or at least partially overlaps with the orthographic projection of the edge portion 312 on the substrate 10.

[0035] The substrate 10 mainly serves as a support and bearing material. Other film layers are stacked sequentially on the substrate 10. The stacking mentioned here means that the other film layers are arranged sequentially along the thickness direction of the substrate 10.

[0036] The heating layer 20 is located on one side of the substrate 10. The heating layer 20 includes heating traces 21. There can be multiple heating traces 21. The heating traces 21 themselves have a certain resistance. When in use, a voltage signal can be provided to the heating traces 21 to generate current in the heating traces 21, so that the heating traces 21 can generate heat and achieve the heating effect on the display panel, so that the display panel can display normally in a low temperature environment.

[0037] Both the first electrode layer 30 and the liquid crystal layer 40 are located on the side of the heating layer 20 facing away from the substrate 10. The first electrode layer 30 includes a plurality of first electrodes 31, and the liquid crystal layer 40 includes a plurality of liquid crystals. The first electrodes 31 are pixel electrodes used to drive the deflection movement of the liquid crystals. When the display panel is in use, by providing a voltage signal to the first electrodes 31, the first electrodes 31 and other specific conductive structures can jointly form a specific electric field. The electric field can drive the deflection movement of the liquid crystals, so that the display panel can display a specific image.

[0038] The first electrode 31 includes a body portion 311 and an edge portion 312 located on at least one side of the body portion 311. The body portion 311 and the edge portion 312 are integrally formed, and the edge portion 312 is connected to the edge of the body portion 311. The number of edge portions 312 can be one or more. When there are multiple edge portions 312, they are distributed at different edge positions of the body portion 311. It should be noted that the specific size and shape of the body portion 311 and the edge portion need to be determined according to the actual use of the display panel, and this application embodiment does not impose any limitations on this.

[0039] Due to the display panel size, at least a portion of the orthographic projection of the heating trace 21 onto the substrate 10 is adjacent to or overlaps with the orthographic projection of the edge portion 312 onto the substrate 10. Specifically, the orthographic projection of the heating trace 21 onto the substrate 10 may overlap with the orthographic projection of the edge portion 312 onto the substrate 10; or the orthographic projection of the heating trace 21 onto the substrate 10 and the orthographic projection of the edge portion 312 onto the substrate 10 may not overlap, but the distance between their orthographic projections is small or even abuts each other.

[0040] Furthermore, since at least a portion of the heating trace 21 in the orthographic projection of the substrate 10 is adjacent to or overlaps with the orthographic projection of the edge portion 312 in the substrate 10, when the heating trace 21 needs to be energized for heating, the heating trace 21 and the edge portion 312 will together form, for example... Figure 1 The lateral electric field shown is illustrated by dashed lines. This lateral electric field covers at least a portion of the structure in the liquid crystal layer 40, thereby affecting the deflection of the liquid crystal and potentially causing display abnormalities.

[0041] To address this, this embodiment of the application adds a shielding portion 50 within the display panel, the shielding portion 50 being disposed on the side of the heating layer 20 facing away from the substrate 10. For example... Figure 1 As shown, the shielding portion 50 can be located on the side of the liquid crystal layer 40 away from the substrate 10.

[0042] The orthographic projection of the shielding portion 50 on the substrate 10 is adjacent to or at least partially overlaps with the orthographic projection of the edge portion 312 on the substrate 10. Specifically, the orthographic projection of the shielding portion 50 on the substrate 10 may have an overlapping area with the orthographic projection of the edge portion 312 on the substrate 10, or the orthographic projection of the shielding portion 50 on the substrate 10 and the orthographic projection of the edge portion 312 on the substrate 10 may not overlap, but the distance between the two orthographic projections is small or even touches each other.

[0043] Since the lateral electric field is generated jointly by the edge portion 312 and the heating trace 21, the liquid crystal that is abnormally deflected due to the influence of the lateral electric field is usually located near the edge portion 312. In this case, in this embodiment, the shielding portion 50 is disposed on the side of the liquid crystal layer 40 facing away from the substrate 10, and its orthographic projection on the substrate 10 is adjacent to or at least partially overlaps with the orthographic projection of the edge portion 312 on the substrate 10. Thus, the shielding portion 50 can, to a certain extent, shield the abnormally deflected liquid crystal, thereby improving the display effect of the display panel.

[0044] In some alternative embodiments, please refer to Figure 2 The shielding portion 50 can also be located between the liquid crystal layer 40 and the heating layer 20. Specifically, the shielding portion 50 is a conductive structure and is relatively close to the edge portion 312 or the heating trace 21. Since its orthographic projection on the substrate 10 is adjacent to or at least partially overlaps with the orthographic projection of the edge portion 312 on the substrate 10, the shielding portion 50 is at least partially located within the range corresponding to the lateral electric field, thereby hindering the lateral electric field to a certain extent, and may even affect the generation of the lateral electric field, thereby reducing the influence of the lateral electric field on the liquid crystal and improving display reliability.

[0045] In this embodiment, a shielding portion 50 is added to the display panel. When the shielding portion 50 is located between the liquid crystal layer 40 and the heating layer 20, it can impede the lateral electric field, thereby ensuring reliable and stable liquid crystal deflection and movement, and improving display reliability. When the shielding portion 50 is located on the side of the liquid crystal layer 40 away from the substrate 10, it can block liquid crystals prone to deflection abnormalities, thereby improving the display reliability of the display panel. In summary, regardless of which side of the liquid crystal layer 40 the shielding portion is located on, the presence of the shielding portion 50 can reduce the probability of display abnormalities and improve the display reliability of the display panel.

[0046] It should be noted that, in addition to the aforementioned film layers, the display panel may also include other film layers. The specific film layer structure within the display panel needs to be determined based on the actual situation, and this application embodiment does not impose excessive restrictions. For example, the display panel may also include a second electrode layer 60. The second electrode layer 60 may be located on the side of the liquid crystal layer 40 facing away from the substrate 10, or it may be sandwiched between the first electrode layer 30 and the liquid crystal layer 40. The second electrode layer 60 includes a second electrode 61. The first electrode 31 and the second electrode 61 can jointly form a specific electric field for driving the deflection motion of the liquid crystal, thereby achieving display reliability of the display panel.

[0047] In addition, the display panel may also include thin-film transistors (not shown in the figure), which include a gate, a source, a drain, and a channel region. Exemplarily, the heating trace 21 may be disposed on the same layer as the gate, or the heating trace 21 may be disposed on the same layer as the source; this application embodiment does not limit this.

[0048] In some embodiments, such as Figure 2 As shown, the shielding portion 50 includes a conductive material and is located on the side of the liquid crystal layer 40 facing the substrate 10. The shielding portion 50 is located between the heating layer 20 and the liquid crystal layer 40. The shielding portion 50 may be located within the first electrode layer 30, or it may be located on the side of the first electrode layer 30 facing or away from the substrate 10. This embodiment does not limit this.

[0049] Since the shielding portion 50 is located on the side of the liquid crystal layer 40 facing the substrate 10, and the orthographic projection of the shielding portion 50 on the substrate 10 is adjacent to or at least partially overlaps with the orthographic projection of the edge portion 312 on the substrate 10, at least a portion of the structure in the shielding portion 50 can be located within the coverage area of ​​the lateral electric field formed by the edge portion 312 and the heating trace 21.

[0050] Based on this, the shielding portion 50 includes a conductive material, thus enabling it to interfere with and impede the lateral electric field, thereby reducing the size of the area covered by the lateral electric field, or even preventing its generation. This reduces the interference of the lateral electric field on the liquid crystal within the liquid crystal layer 40, improves the reliability of liquid crystal deflection and movement, and ultimately enhances the display reliability of the display panel.

[0051] It should be noted that the specific material used in the shielding portion 50 is not limited in this embodiment. For example, the shielding portion 50 may include metallic materials such as silver, aluminum, and titanium. Furthermore, depending on actual usage needs, the display panel may or may not provide a voltage signal to the shielding portion 50; this embodiment does not impose any limitations on this.

[0052] In some embodiments, please refer to Figure 3 The display panel also includes a second electrode layer 60 disposed between the liquid crystal layer 40 and the first electrode layer 30. The second electrode layer 60 includes a second electrode 61, and the first electrode 31 and the second electrode 61 together drive the liquid crystal movement; wherein, the blocking part 50 is located within the second electrode layer 60.

[0053] The first electrode layer 30 and the second electrode layer 60 are located on the same side of the liquid crystal. The first electrode 31 in the first electrode layer 30 and the second electrode 61 in the second electrode layer 60 can jointly form a specific electric field for driving the deflection motion of the liquid crystal, so that the display panel can display a specific image.

[0054] The shielding part 50 is located within the second electrode layer 60, meaning that the shielding part 50 and the second electrode 61 are disposed on the same layer. The shielding part 50 can be connected to the second electrode 61 to achieve an electrical connection between them; alternatively, the shielding part 50 can be spaced apart from the second electrode 61 to prevent signal transmission between them. When the shielding part 50 and the second electrode 61 are spaced apart, an insulating material can be arranged between them to improve the insulation effect; alternatively, depending on the actual situation, no insulating material may be arranged between them.

[0055] Both the shielding portion 50 and the second electrode 61 include conductive materials. The material of the shielding portion 50 can be the same as or different from that of the second electrode 61, and this embodiment of the application does not impose any limitations on this. For example, the second electrode 61 may include at least one of indium tin oxide (ITO), indium zinc oxide, silver-doped indium tin oxide, and silver-doped indium zinc oxide.

[0056] In this embodiment, since both the shielding portion 50 and the second electrode 61 are within the second electrode layer 60, the increase in the overall thickness of the display panel can be avoided by setting the shielding portion 50 above or below the film layer where the second electrode 61 is located, which is beneficial to achieving a thinner display panel.

[0057] In some embodiments, the second electrode 61 includes a plurality of strip electrodes 611, and the shielding portion 50 is at least partially located between adjacent strip electrodes 611.

[0058] The second electrode 61 includes a plurality of strip electrodes 611, wherein the second electrode 61 can be a domain electrode, and the domain structure mentioned here includes, but is not limited to, horizontal domain structure, vertical domain structure, and multi-domain structure. The plurality of strip electrodes 611 are arranged at intervals from each other, and in a single second electrode 61, the ends of the plurality of strip electrodes 611 are connected to each other in their own extension direction.

[0059] The shielding portion 50 is at least partially located between adjacent strip electrodes 611, and the number of shielding portions 50 can be one or more. When there are multiple shielding portions 50, the multiple shielding portions 50 can be disposed between different adjacent strip electrodes 611. Furthermore, the shielding portion 50 can be connected to the strip electrode 611 to have the same voltage signal; or the shielding portion 50 can also be spaced apart from and insulated from the strip structure.

[0060] In some embodiments, please refer to Figure 4 The shielding part 50 is connected to the strip electrode 611.

[0061] As described above, the shielding part 50 is disposed on the same layer as the second electrode 61, and the shielding part 50 is located between adjacent strip electrodes 611. Based on this, in this embodiment, the shielding part 50 is also connected to the strip electrodes 611. Depending on the actual situation, the shielding part 50 can be connected to one of the two strip electrodes 611 located on either side of it, or it can be connected to both strip electrodes 611 simultaneously. This application does not impose any restrictions on this. For example, the shielding part 50 is connected to both strip electrodes 611 simultaneously, that is, the shielding part 50 can achieve electrical connection between the two strip electrodes 611.

[0062] Furthermore, the shielding portion 50 and the strip electrode 611 can be made of the same material or different materials. In this embodiment, by connecting the shielding portion 50 to the strip electrode 611, it is not necessary to ensure the shielding portion 50 avoids the strip electrode 611 during fabrication. This reduces the fabrication difficulty of the shielding portion 50 and helps improve the fabrication efficiency of the display panel.

[0063] In some embodiments, please refer to Figure 5 The shielding part 50 is integrally formed with the strip electrode 611.

[0064] The phrase "the shielding portion 50 and the strip electrode 611 are integrally formed" mentioned in this application embodiment refers to the fact that the shielding portion 50 and the strip electrode 611 are formed of the same material and are located in the same film layer. Therefore, in the manufacturing process, the shielding portion 50 and the strip electrode 611 can be fabricated simultaneously using a single mask, thereby reducing the number of process steps and helping to improve process efficiency.

[0065] In some embodiments, please refer to Figure 6 The second electrode layer 60 is located between the liquid crystal layer 40 and the first electrode layer 30, and the shielding portion 50 is at least partially located on the side of the second electrode layer 60 away from the substrate 10.

[0066] At least a portion of the shielding portion 50 is located in a different film layer from the second electrode 61. Specifically, the shielding portion 50 may be completely located on the side of the second electrode layer 60 away from the substrate 10, or the shielding portion 50 may be partially located on the side of the second electrode layer 60 away from the substrate 10, and partially located within the second electrode layer 60 at the same time as the second electrode 61.

[0067] Furthermore, at least a portion of the structure in the shielding portion 50 located on the side of the second electrode layer 60 facing away from the substrate 10 may or may not have an insulating layer sandwiched between it and the second electrode layer 60. In other words, the shielding portion 50 may be insulated from the second electrode 61, or the shielding portion 50 may overlap the second electrode 61.

[0068] In this embodiment, the shielding portion 50 is at least partially located on the side of the second electrode layer 60 away from the substrate 10. This reduces the space occupied by the shielding portion 50 within the second electrode layer 60, thereby helping to set more second electrodes 61 within the second electrode layer 60 or reduce the distance between adjacent second electrodes 61. This is applicable to display panels in high-resolution applications and has strong practicality.

[0069] In some embodiments, please refer to Figure 7 There are multiple second electrodes 61, and the shielding part 50 is partially embedded between adjacent second electrodes 61.

[0070] In this embodiment of the application, the phrase "the shielding portion 50 is partially embedded between adjacent second electrodes 61" refers to the following: a portion of the structure in the shielding portion 50 is disposed on the same layer as the second electrode 61, and this portion of the structure is located between two adjacent second electrodes 61. Specifically, the portion of the shielding portion 50 embedded between adjacent second electrodes 61 can be connected to the adjacent second electrode 61, or it can be spaced apart from the adjacent second electrode 61.

[0071] Different display panels have different internal structural layouts. For example, in some display panels, the distance between adjacent second electrodes 61 is reduced to achieve higher resolution. In this case, the space between adjacent second electrodes 61 cannot meet the arrangement requirements of the shielding portion 50. Therefore, part of the structure of the shielding portion 50 can be embedded between adjacent second electrodes 61, and the other part of the structure can be placed on the side of the second electrode layer 60 facing away from the substrate 10, thereby meeting the arrangement requirements of the shielding portion 50.

[0072] Furthermore, since the shielding portion 50 is partially embedded between adjacent second electrodes 61, it can reduce the space occupied by the shielding portion 50 for other film layers to a certain extent, thereby facilitating the layout of functional components such as wiring and meeting the design requirements of the display panel.

[0073] In some embodiments, please refer to Figure 8 The shielding part 50 is located inside the first electrode layer 30 and connected to the first electrode 31.

[0074] The shielding part 50 is disposed in the same layer as the first electrode 31, which can reduce the space occupied by the shielding part 50 on other film layers, or can avoid the increase in the number of film layers inside the display panel due to the presence of the shielding part 50, thereby facilitating the thinning of the display panel.

[0075] The shielding portion 50 is connected to the first electrode 31, and further, the shielding portion 50 is connected to the edge portion 312. As described above, the edge portion 312 and the heating trace 21 together form a lateral electric field. Based on this, the shielding portion 50 is connected to the edge portion 312 and located on one side of the edge portion 312, so that the shielding portion 50 is within the range covered by the lateral electric field. The shielding portion 50 can play the role of hindering the lateral electric field, thereby reducing the impact of the lateral electric field on the liquid crystal and improving the display reliability of the display panel.

[0076] It should be noted that the shielding portion 50 can be made of the same material as the first electrode 31, or it can be made of a different material. For example, the shielding portion 50 and the first electrode 31 are made of the same material, and the shielding portion 50 and the first electrode 31 can be formed simultaneously using the same mask, thereby improving the fabrication efficiency.

[0077] In some embodiments, such as Figure 1 As shown, the shielding portion 50 is located on the side of the liquid crystal layer 40 away from the substrate 10.

[0078] As described above, since the lateral electric field is generated jointly by the edge portion 312 and the heating trace 21, the liquid crystal that is abnormally deflected due to the influence of the lateral electric field is usually located near the edge portion 312. Based on this, in this embodiment, the shielding portion 50 is disposed on the side of the liquid crystal layer 40 facing away from the substrate 10, and the orthographic projection of the shielding portion 50 onto the substrate 10 is adjacent to or at least partially overlaps with the orthographic projection of the edge portion 312 onto the substrate 10. This allows the shielding portion 50 to effectively shield the abnormally deflected liquid crystal to a certain extent, thereby improving the display effect of the display panel.

[0079] It should be noted that the shielding portion 50 provided in this application embodiment can be made of a non-transparent material or a transparent material. Specifically, even if the shielding portion 50 is made of a transparent material, the presence of the shielding portion 50 can still reduce the transmittance of the display panel at the corresponding position, thereby reducing the impact of abnormal liquid crystal deflection on the display effect.

[0080] In some embodiments, please refer to Figure 9 The display panel also includes a light-shielding layer 70 disposed on the side of the liquid crystal layer 40 away from the substrate 10. The light-shielding layer 70 includes a light-shielding portion 71, which defines a plurality of opening regions K. The blocking portion 50 is located in the blocking layer and is at least partially located in the opening region K.

[0081] The light-shielding part 71 can be used to block the wiring and some functional components inside the display panel to improve the display effect. The light-shielding part 71 can define and form multiple opening areas K. The shape, structure and number of opening areas K are not limited in this embodiment. For example, the light-shielding part 71 can be a black matrix, and the multiple opening areas K defined by the black matrix are correspondingly arranged with multiple light-emitting areas in the display panel.

[0082] Meanwhile, in this embodiment, the blocking part 50 is also located in the light-shielding layer 70. This design can avoid the problem of the overall thickness of the display panel increasing due to the presence of the blocking part 50, thereby facilitating the thinning of the display panel.

[0083] It should be noted that the blocking part 50 is located within the opening area K. The blocking part 50 may or may not be connected to the light-shielding part 71. Furthermore, the blocking part 50 may be made of the same material as the light-shielding part 71 or may be made of a different material. This application embodiment does not impose any restrictions on this.

[0084] In some embodiments, please refer to Figure 10 The shielding part 50 is connected to the light-shielding part 71, and the two are integrally formed.

[0085] The phrase "the shielding part 50 and the light-shielding part 71 are integrally formed" mentioned in the embodiments of this application refers to the fact that the top part of the shielding part 50 and the light-shielding part 71 are formed of the same material and are located in the same film layer. Therefore, in the manufacturing process, the shielding part 50 and the light-shielding part 71 can be manufactured simultaneously with a single mask, thereby reducing the number of manufacturing steps and improving the manufacturing efficiency of the display panel.

[0086] Secondly, please refer to Figure 11 This application provides a display device, including the display panel in any of the foregoing embodiments.

[0087] It should be noted that the display device provided in this application embodiment has the beneficial effects of the display panel in any of the foregoing embodiments.
