Description

Technical Field

[0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background Art

[0002] Liquid crystal is a special form of matter that possesses both the birefringence unique to crystals and the fluidity of liquids. Liquid crystal displays (LCDs) are display devices made by changing the optical properties of liquid crystal molecules under the action of an external electric field. They come in various types and are currently widely used in various displays and electronic instruments. However, due to the limitations of liquid crystal materials, the response time of liquid crystals is prolonged at low temperatures. When the response time of liquid crystals is prolonged, the display quality deteriorates, and dynamic images experience problems such as tailing and smearing, which affects the visual effect. When the temperature drops further (below -30°C), the orientation layer of the display will be destroyed, the liquid crystal state will disappear, and it will become crystalline, losing its liquid crystal properties, and the image will not be displayed.

[0003] To solve the above problem, a current heating method is to introduce heating traces into the display panel. However, the electric field formed between the heating traces and other conductive layers will affect the normal deflection of the liquid crystal and affect the overall display effect. Summary of the Invention

[0004] In view of this, the present invention provides a display panel and a display device, which are helpful in reducing or avoiding the influence of the electric field formed by the heating wiring and the common electrode on the display effect.

[0005] In a first aspect, the present invention provides a display panel, comprising a display area and a non-display area located outside the display area, comprising:

[0006] a first substrate;

[0007] A common electrode and a plurality of pixel electrodes are provided on one side of the first substrate, wherein the common electrode is located on a side of the pixel electrodes facing away from the substrate;

[0008] a plurality of data lines, the data lines being arranged along a first direction and extending along a second direction; the data lines being located between the pixel electrodes and the first substrate along a thickness direction of the display panel; and the data lines being located between two adjacent pixel electrodes along the first direction, with a first gap being formed between adjacent data lines and pixel electrodes;

[0009] A heating trace and a conductive portion, wherein the heating trace is at least located in the display area, and both the heating trace and the conductive portion are located on the side of the pixel electrode facing the first substrate; along a direction perpendicular to the first substrate, the heating trace overlaps with the first interval to form a first area, and the conductive portion's orthographic projection on the first substrate covers the first area.

[0010] In a second aspect, based on the same inventive concept, the present application provides a display device comprising the display panel provided by the first aspect of the present application.

[0011] Compared with the prior art, the display panel and the display device provided by the present application at least achieve the following beneficial effects:

[0012] In the display panel and the display device provided by the present application, the common electrode and the plurality of pixel electrodes are arranged on the first substrate, the pixel electrodes are located between the common electrode and the first substrate, and the electric field generated between the pixel electrodes and the common electrode is used to drive the liquid crystal to deflect. The display panel further comprises a plurality of data lines arranged in the first direction and extending in the second direction, and the film layer where the data lines are located is located on the side of the film layer where the pixel electrodes are located towards the first substrate. The orthographic projection of the data line on the first substrate is located between the two pixel electrodes arranged in the first direction, and the orthographic projection of the data line on the first substrate and the orthographic projection of the pixel electrode adjacent to the data line on the first substrate have a first interval. When the heating trace is introduced into the display panel, the heating trace and the first interval overlap to form a first area. If the conductive part is not introduced, an electric field will be formed between the heating trace and the common electrode in the first area, which will cause the liquid crystal in the first area and the adjacent area to deflect abnormally, affecting the display effect. The conductive part introduced in the display panel of the embodiment of the present application covers the first area in the orthographic projection on the first substrate, so as to block the formation of the electric field between the heating trace and the common electrode, or to shield the light emitted by the backlight module from the area where the liquid crystal deflects abnormally, so as to avoid the abnormal deflection phenomenon being recognized by the human eye, thereby being beneficial to ensuring the display effect of the display panel when the heating trace is introduced into the display panel.

[0013] Of course, any product implementing the present application does not necessarily need to achieve all the technical effects described above at the same time.

[0014] Other features of the present application and its advantages will become apparent from the following detailed description of exemplary embodiments thereof, with reference to the drawings. BRIEF DESCRIPTION OF DRAWINGS

Therefore, the present invention is intended to cover modifications and variations of the present invention that fall within the scope of the corresponding claims (technical solutions claimed for protection) and their equivalents. It should be noted that the embodiments provided in the embodiments of the present invention may be combined with each other unless there is any contradiction.

[0051] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0052] Figure 1 FIG. 1 is a top view of a display panel provided by an embodiment of the present invention. Figure 2 Shown Figure 1 A relative position relationship diagram of the pixel electrode, data line, heating trace and conductive part. Figure 3 Shown Figure 2 An AA cross-section diagram, please combine Figures 1 to 3 An embodiment of the present invention provides a display panel 100, which includes a display area A1 and a non-display area A2 located outside the display area A1, including:

[0053] First substrate 00;

[0054] A common electrode T2 and a plurality of pixel electrodes T1 are provided on one side of the first substrate 00 , wherein the common electrode T2 is located on a side of the pixel electrode T1 facing away from the first substrate 00 ;

[0055] A plurality of data lines DL are arranged along a first direction F1 and extend along a second direction F2; along the thickness direction of the display panel, the data lines DL are located between the pixel electrodes T1 and the first substrate 00; along the first direction F1, the data lines DL are located between two adjacent pixel electrodes T1, and a first interval X is formed between adjacent data lines DL and pixel electrodes T1;

[0056] The heating trace 10 and the conductive portion 20 are located at least in the display area A1. The heating trace 10 and the conductive portion 20 are both located on the side of the pixel electrode T1 facing the first substrate 00. Along the direction perpendicular to the first substrate 00, the heating trace 10 overlaps with the first interval X to form a first area Q1, and the conductive portion 20's orthographic projection on the first substrate 00 covers the first area Q1.

[0057] It should be noted that Figure 1 The rectangular display panel is used as an example for description, and the shape of the display panel is not limited. In some other embodiments of the present invention, the shape of the display panel may also be other shapes, such as a rounded rectangle, a circle, or other feasible shapes. Figure 1 Only one arrangement of the pixel electrodes T1 included in the display panel is illustrated, and the number, shape and size of the pixel electrodes T1 actually included in the display panel are not limited. Figure 3 Only one film layer in the display area is illustrated, and does not represent the actual number and size of film layers included in the display panel.

[0058] Optionally, the display panel provided in the embodiment of the present invention is a liquid crystal display panel. The embodiment of the present invention introduces a heating line 10 in the display panel, which can heat the display panel in a low temperature environment, thereby realizing the use function of the display panel in a low temperature environment.

[0059] Please combine Figures 1 to 3 In the display panel 100 provided by the present invention, a common electrode T2 and multiple pixel electrodes T1 are provided on a first substrate 00. The pixel electrode T1 is located between the common electrode T2 and the first substrate 00. The electric field generated between the pixel electrode T1 and the common electrode T2 is used to drive the deflection of the liquid crystal. The display panel is also provided with multiple data lines DL arranged along a first direction F1 and extending along a second direction F2. The film layer on which the data lines DL are located is located on the side of the film layer on which the pixel electrodes T1 are located that faces the first substrate 00. The data lines DL are used to provide data signals to the sub-pixels in the display panel, thereby forming a pixel voltage on the pixel electrode T1. This pixel voltage has a voltage difference with the common voltage on the common electrode T2, forming an electric field between the pixel electrode T1 and the common electrode T2, thereby driving the liquid crystal and achieving the display function of the display panel.

[0060] Continue to refer Figure 1 and Figure 2The orthographic projection of the data line DL on the first substrate 00 is located between two pixel electrodes T1 arranged along the first direction F1, and a first gap X is formed between the orthographic projection of the data line DL on the first substrate 00 and the orthographic projection of the pixel electrode T1 adjacent to the data line DL on the first substrate 00. When the heating trace 10 is introduced into the display panel, the heating trace 10 overlaps with the first gap X to form a first region Q1. If no conductive portion is introduced, for example, please refer to Figure 4 In the aforementioned first area Q1, the heating trace 10 is arranged opposite to the common electrode T2. An electric field is formed between the heating trace 10 and the common electrode T2 to drive the abnormal deflection of the liquid crystal in the first area Q1. When the light of the backlight module is directed to the abnormally deflected liquid crystal in the first area, abnormal display will occur in this area, affecting the display effect. Figure 4 The figure shows a structural diagram in which no conductive part is introduced into the display panel.

[0061] To do this, refer to Figure 3 In an embodiment of the present invention, a conductive portion 20 is introduced into the display panel. The orthographic projection of the conductive portion 20 on the first substrate 00 covers the first region Q1. One arrangement of the conductive portion 20 in the display panel is to arrange the conductive portion 20 between the heating trace 10 and the common electrode T2. The conductive portion 20 can function as an electric field shield, thereby preventing the formation of an electric field between the heating trace 10 and the common electrode T2, thereby preventing abnormal deflection of the liquid crystal in the first region Q1, thereby facilitating the avoidance of abnormal display problems on the display panel and ensuring the display effect of the display panel when the heating trace 10 is introduced into the display panel.

[0062] Another arrangement of the conductive portion 20 in the display panel is to arrange the conductive portion 20 on a side of the heating trace 10 close to the substrate 00, for example, see Figure 5 In this case, even if the electric field formed by the heating trace 10 and the common electrode T2 causes abnormal deflection of the liquid crystal, the conductive portion 20 can block the light irradiated by the backlight module to the abnormal deflection area, thereby preventing the human eye from recognizing the abnormal display phenomenon. Therefore, it is also beneficial to ensure the display effect of the display panel when the heating trace 10 is introduced into the display panel. Figure 5 Shown Figure 2 Another AA cross-section view.

[0063] Figure 6 Shown Figure 2 A BB cross-section diagram of Figure 3 and Figure 6In an optional embodiment of the present invention, the display panel includes a first substrate 101 and a second substrate 102 arranged opposite to each other and liquid crystal (not shown in the figure) filled between the first substrate 101 and the second substrate 102. The first substrate 01 includes a first substrate 00 and a pixel electrode T1; the second substrate 102 includes a second substrate 02 and a common electrode T2, and the common electrode T2 is located on the side of the second substrate 02 facing the first substrate 01.

[0064] Optionally, the first substrate 01 is an array substrate, and the second substrate 102 is an opposing substrate. This embodiment illustrates a solution in which the pixel electrode T1 is disposed on the array substrate, and the common electrode T2 is disposed on the opposing substrate. Optionally, each sub-pixel in the display area A1 corresponds to a pixel electrode T1, and the common electrode T2 is a planar electrode, with the orthographic projection of the common electrode T2 on the first substrate 00 overlapping the orthographic projections of each pixel electrode T1 in the display area A1 on the first substrate 00. When signals are supplied to the pixel electrode T1 and the common electrode T2, respectively, a vertical electric field is formed in the region between the pixel electrode T1 and the common electrode T2. This vertical electric field acts on the liquid crystal between the opposing substrate and the array substrate, driving the liquid crystal to deflect, thereby realizing the display function of the display panel. When the pixel electrode T1 and the common electrode T2 are disposed on the first substrate 01 and the second substrate 102, respectively, the liquid crystal molecules deflect quickly, the response time is short, and display ghosting is less likely to occur.

[0065] When the display panel provided by this embodiment is used, the common electrode T2 is provided on the second substrate 102. When the heating trace 10 and the conductive portion 20 are introduced, the heating trace 10 and the conductive portion 20 are both located on the first substrate 01, and the orthographic projection of the conductive portion 20 on the first substrate 00 covers the first area Q1. Figure 3 In the structure shown in FIG. 1 , the conductive portion 20 can play the role of electric field shielding, and the conductive portion 20 is used to prevent the heating trace 10 and the common electrode T2 from forming an electric field in the first area Q1, thereby avoiding abnormal display problems of the display panel and ensuring the display effect of the display panel. Figure 5 In the structure shown, the conductive portion 20 plays a light-shielding role. Even if an electric field is formed between the heating trace 10 and the common electrode T2, causing the liquid crystal in the first area Q to be abnormally deflected, the conductive portion 20 can also block the light emitted by the backlight module from being directed to the area where the abnormally deflected liquid crystal is located, thereby avoiding display abnormalities and ensuring the display effect of the display panel.

[0066] The above embodiment shows a solution in which the pixel electrode and the common electrode are respectively arranged in the array substrate and the counter substrate. In some other embodiments of the present invention, the pixel electrode and the common electrode can also be arranged in the array substrate. For example, please refer to Figure 7 and Figure 8 ,in, Figure 7 Shown Figure 2 Another AA cross-section diagram, Figure 8 Shown Figure 2 Another BB cross-section diagram.

[0067] Please refer to Figure 7 and Figure 8 In an optional embodiment of the present invention, the display panel includes a first substrate 101 and a second substrate 102 arranged opposite to each other and liquid crystal (not shown in the figure) filled between the first substrate 101 and the second substrate 102, and the first substrate 101 includes a first substrate 00, a pixel electrode T1 and a common electrode T2.

[0068] Optionally, the first substrate 101 is an array substrate, and the second substrate 102 is an opposing substrate. This embodiment shows a solution in which both the pixel electrode T1 and the common electrode T2 are disposed on the array substrate, and the common electrode T2 is disposed on the side of the pixel electrode T1 facing away from the first substrate 00. Since the electric field generated between the pixel electrode T1 and the common electrode T2 needs to act on the liquid crystal between the first substrate 101 and the second substrate 102 to drive the liquid crystal deflection, when the common electrode T2 and the pixel electrode T1 are both disposed on the array substrate, a slit design is required on the common electrode T2 so that the electric field can act on the liquid crystal through the slit. At the same time, when the common electrode T2 is designed with a slit, it is also beneficial to improve the resolution and aperture ratio of the display panel.

[0069] If a heating trace is introduced into the display panel without introducing a conductive part, for example, please refer to Figure 9 Since there is a first gap X between the data line DL and the pixel electrode T1, when the voltage of the heating line 10 is different from the voltage of the common electrode T2, an electric field will be generated between the heating line 10 and the common electrode T2, which will cause abnormal deflection of the liquid crystal and affect the display effect. Figure 9 The figure shows a structural diagram in which no conductive part is introduced into the display panel.

[0070] To do this, refer to Figure 7 When the present invention introduces the heating trace 10 into the display panel, it further introduces a conductive portion 20. Optionally, the conductive portion 20 is arranged between the heating trace 10 and the pixel electrode T1 along the thickness direction of the display panel, and the conductive portion 20 covers the first region Q1. In this way, the conductive portion 20 can play an electric field shielding role, preventing the formation of an abnormal electric field between the heating trace 10 and the common electrode T2, which would cause abnormal deflection of the liquid crystal, and thus cause abnormal display of the display panel. Of course, in some other embodiments of the present invention, the conductive portion 20 can also be arranged on the side of the heating trace facing the first substrate. The light shielding effect of the conductive portion 20 can prevent the light of the backlight module from being directed to the area where the abnormally deflected liquid crystal is located, thereby avoiding the problem of abnormal display of the display panel.

[0071] Figure 10 FIG. 1 is a top view of the data line DL, the pixel electrode T1, the heating trace 10 and the conductive portion 20. Figure 11 Shown Figure 2 Another AA cross-section view.

[0072] Please refer to Figures 10 and 11 In an optional embodiment of the present invention, the conductive portion 20 includes a main portion 21 and a first extension portion 22 connected to the main portion 21. Along the first direction F1, the first extension portion 22 is located on one side of the main portion 21; the orthographic projection of the main portion 21 on the first substrate 00 covers the first region Q1, and the orthographic projection of the first extension portion 22 on the first substrate 00 overlaps with the orthographic projection of the pixel electrode T1 on the first substrate 00.

[0073] Specifically, the data line DL and the pixel electrode T1 are respectively arranged on either side of the first interval X. The area where the heating trace 10 overlaps with the first interval X is the first region Q1. The main portion 21 of the conductive portion 20 is located in this first region Q1. The first extension 22 can be considered as the portion extending from the main portion 21 toward the pixel electrode T1. The first extension 22 extends to at least a portion of the area directly below the pixel electrode T1. In other words, the orthographic projection of the first extension 22 on the first substrate 00 overlaps with the orthographic projection of the pixel electrode T1 on the first substrate 00. When an electric field is formed between the heating trace 10 and the common electrode T2, the electric field is likely to act on the liquid crystal in a portion of the first region Q1 near the pixel electrode T1, causing abnormal deflection of the liquid crystal in this portion. This portion corresponds to the area directly above the first extension 22. When the conductive portion 20 is arranged on the side of the heating trace 10 close to the first substrate 00, the conductive portion 20 can block light. The first extension portion 22 in the conductive portion 20 can block the light emitted by the backlight module from irradiating the area where the abnormally deflected liquid crystal is located. Therefore, even if the liquid crystal in the part of the first area Q1 toward the pixel electrode is abnormally deflected, the human eye will not notice the problem of abnormal deflection of the liquid crystal, and thus will not affect the display effect of the display panel.

[0074] Of course, in some other embodiments of the present invention, when the conductive portion 20 includes the main body portion 21 and the first extension portion 22, the conductive portion 20 can also be disposed in the film layer between the common electrode T2 and the heating trace 10. In this case, the conductive portion 20 plays the role of electric field shielding. For example, please refer to Figure 12 , Figure 12 Shown Figure 2In another AA cross-sectional view, after the first extension portion 22 is introduced into the conductive portion 20, the coverage area of ​​the conductive portion 20 is increased, thereby increasing the electric field shielding area of ​​the conductive portion 20. This is beneficial to further block the heating trace 10 and the common electrode T2 from forming an electric field, thereby helping to avoid the problem of abnormal deflection of the liquid crystal caused by the electric field, and also helping to ensure the display effect of the display panel.

[0075] It should be noted that the main body 21 and the first extension portion 22 in the conductive portion 20 only divide the structures of different areas of the same conductive portion 20. The main body 21 and the first extension portion 22 in the same conductive portion 20 can be integrally formed, that is, made of the same material and in the same process.

[0076] Continue to refer Figures 10 to 12 In an optional embodiment of the present invention, along a direction perpendicular to the first substrate 00, the first extension portion 22 includes a first edge B1 overlapping with the pixel electrode T1, and the first edge B1 and the pixel electrode T1 overlapping therewith are arranged opposite to each other toward the outer edge of the main body 21, and a distance between the first edge B1 and the outer edge is D0, and D0 ≥ 3 μm.

[0077] Specifically, the first edge B1 of the first extension 22 can be considered as the edge extending directly below the pixel electrode T1 and opposite the first gap X. The outer edge of the pixel electrode T1 facing the main portion 21 can be considered as the outer edge of the pixel electrode T1 adjacent to the first gap X. The distance between the first edge B1 of the first extension 22 and the outer edge of the pixel electrode T1 can be considered as the overlap width between the first extension 22 and the pixel electrode T1 along the alignment direction of the data line DL and the pixel electrode T1. When the cell thickness of the display panel is fixed, if the overlap width is small, for example, less than 3μm, the electric field formed between the heater trace 10 and the common electrode T2 is likely to cause abnormal deflection of the liquid crystal corresponding to the area of ​​the pixel electrode T1 near the first gap X, thus affecting the display effect. Therefore, when D0 is set to ≥ 3μm, the area affected by the electric field formed between the heater trace 10 and the common electrode T2 on the liquid crystal directly above the pixel electrode T1 is effectively covered, thereby effectively preventing display anomalies caused by abnormal liquid crystal deflection that are visible to the human eye.

[0078] by Figure 11Taking the embodiment shown as an example, wherein viewing angle 1 is a viewing angle of the human eye when observing the display panel of the current thickness, and viewing angle 2 is a viewing angle of the human eye when observing the display panel with increased thickness when the thickness of the display panel increases, viewing angle 1 and viewing angle 2 are the same viewing angle. Assuming that region Q0 is the region affected by the electric field between the heating trace 10 and the common electrode T2, and assuming that it is required that the human eye cannot recognize the abnormal display caused by the abnormal deflection of the liquid crystal at the above-mentioned fixed viewing angle, that is, it is impossible to recognize the abnormal display phenomenon in the above-mentioned region Q0, when the thickness of the display panel increases, at the same viewing angle, it is necessary to increase the width of the extension portion (extend the first extension portion further away from the main body) to avoid observing the abnormal display phenomenon. Therefore, when the thickness of the display panel increases, the width of the first extension portion in the above-mentioned embodiment increases accordingly.

[0079] Figure 13 FIG. 1 is another top view of the data line DL, the pixel electrode T1, the heating trace 10 and the conductive portion 20. Figure 14 Shown Figure 13 A DD-direction cross-section diagram.

[0080] Please refer to Figure 13 and Figure 14 In an optional embodiment of the present invention, the conductive portion 20 further includes a second extension portion 23 connected to both the main portion 21 and the first extension portion 22. The second extension portion 23 is located on opposite sides of the main portion 21 and the first extension portion 22 along the second direction F2. The orthographic projection of the second extension portion 23 on the first substrate 00 overlaps with the orthographic projection of the pixel electrode T1 on the first substrate 00.

[0081] Specifically, this embodiment shows a solution in which the conductive portion 20 further includes a second extension portion 23. The second extension portion 23 can be regarded as a conductive portion 20 extending from the area where the main portion 21 and the second extension portion 23 are located to both sides along the second direction F2. Considering that when an electric field is formed between the heating trace 10 and the common electrode T2, the electric field may radiate from the first area Q1 to the partial areas on both sides of the first area Q1 along the second direction F2, for example, please refer to Figure 15 , Figure 15 For example, the common electrode T2 is located on the second substrate, and the pixel electrode T1 is located on the first substrate. In this case, the area extending from the first region Q1 along the second direction F2 to a certain extent is also within the range of action of the above-mentioned electric field. The liquid crystal in this area will undergo abnormal deflection, wherein: Figure 15The figure shows a schematic diagram of a structure without the second extension portion in the conductive portion. In this embodiment, the second extension portion 23 is introduced into the conductive portion 20 to cover the area where the electric field acts. The conductive portion 20 can be positioned between the heating trace 10 and the pixel electrode T2, shielding the electric field through the shielding effect of the conductive portion 20. The conductive portion 20 can also be positioned on the side of the heating trace 10 close to the first substrate 00, thereby blocking light emitted by the backlight module from reaching the area where the abnormal electric field exists, thereby facilitating the display effect of the display panel.

[0082] Continue to refer Figure 13 In an optional embodiment of the present invention, the orthographic projection of the second extension portion 23 on the first substrate 00 includes a second edge B2, and the second edge B2 is arranged opposite to the orthographic projection of the heating trace 10 on the first substrate 00. The minimum distance between the second edge B2 and the heating trace 10 is D1, and D1 ≥ 3 μm.

[0083] Specifically, the minimum distance between the second edge B2 and the heating trace 10 is D1, which can be regarded as the range of the second extension portion 23 extending outward relative to the main body portion 21 and the first extension portion 22 along the second direction F2, and can also be regarded as the width of the second extension portion 23 along the second direction F2. Assuming that the box thickness of the display panel is fixed, when the width of the second extension portion 23 along the second direction F2 is too small, for example, less than 3μm, the conductive portion 20 as a whole may not be able to cover the range of action of the electric field formed by the heating trace 10 and the common electrode T2 in the first zone Q1, and thus there will still be problems of abnormal deflection of the liquid crystal leading to abnormal display. When the above-mentioned width is set to be greater than or equal to 3μm, the conductive part 20 can cover the coverage range of the electric field formed by the common electrode T2 and the heating trace 10 in the first zone Q1. The shielding effect of the conductive part 20 on the electric field or the shading effect of the conductive part 20 can prevent the abnormal electric field from acting on the above-mentioned area, or even if the electric field acts on the above-mentioned area and causes abnormal deflection of the liquid crystal, the shading effect of the conductive part 20 can prevent the light of the backlight module from irradiating the area where the abnormally deflected liquid crystal is located, thereby avoiding the problem of abnormal display visible to the human eye, and is therefore beneficial to ensuring the overall display effect of the display panel.

[0084] Figure 16 FIG. 1 is another top view of the data line DL, the pixel electrode T1 , the heating trace 10 and the conductive portion 20 .

[0085] Please refer to Figure 1 and Figure 16 In an optional embodiment of the present invention, the orthographic projection of the main body portion 21 on the first substrate 00 overlaps with the orthographic projection of the data line DL on the first substrate 00 .

[0086] Specifically, an embodiment of the present invention illustrates another structure for the main portion 21 of the conductive portion 20. In this embodiment, the main portion 21 has a larger coverage area. In a direction perpendicular to the first substrate 00, the main portion 21 not only overlaps the first spacer X but also overlaps the data line DL. This effectively increases the overall coverage area of ​​the conductive portion 20 on the first substrate 00, thereby increasing the shielding range of the conductive portion 20 against the electric field, or the range of blocking abnormally deflected liquid crystals. This further helps prevent display anomalies visible to the human eye and ensures the display quality of the display panel. In addition, when the display panel has a very high resolution, it is difficult for the black matrix to block light leakage caused by abnormal deflection of the liquid crystal caused by the oblique electric field in the first spacer. Therefore, when the area of ​​the conductive portion 20 is further increased, this oblique electric field can be shielded. Alternatively, light from the backlight module can be prevented from reaching the area of ​​the liquid crystal that is abnormally deflected due to the upper oblique electric field. This helps prevent abnormal display problems visible to the human eye and helps ensure the display quality of the display panel.

[0087] In an optional embodiment of the present invention, the heating trace 10 includes a transparent conductive material.

[0088] Specifically, when the embodiment of the present invention introduces a heating trace 10 to heat the liquid crystal in a low temperature environment, the heating trace 10 converts the electrical signal into heat and acts on the liquid crystal. The heating trace 10 can be made of a transparent conductive material. When the heating trace 10 is placed in the display area A1, if the heating trace 10 is made of an opaque metal material, the heating trace 10 will cause the aperture ratio of the display panel to decrease, affecting the overall transmittance of the display panel. When the heating trace 10 is made of a transparent conductive material, even if the heating trace 10 is placed in the display area A1, light can still pass through the heating trace 10 and be emitted to the light-emitting surface of the display panel, so it will not affect the aperture ratio of the display panel. While achieving the heating of the liquid crystal in the display panel, it is also beneficial to ensure the aperture ratio and transmittance of the display panel.

[0089] Figure 17 Shown Figure 1 A CC cross-sectional view of the display panel in the embodiment shows a film layer structure of the display area A1 in the display panel. Figure 18 Shown Figure 2 Another AA cross-section diagram, Figure 19 Shown Figure 2 Another AA cross-section view.

[0090] Please refer to Figure 17In an optional embodiment of the present invention, the first substrate 101 includes a first metal layer M1 and a second metal layer M2, both of which are located on the side of the pixel electrode T1 facing the first substrate 00, and the first metal layer M1 is located between the second metal layer M2 and the first substrate 00; the first substrate 101 includes a plurality of transistors T, the gates of the transistors T are located in the first metal layer M1, and the sources or drains of the transistors T are located in the second metal layer M2; please refer to Figure 18 , the heating trace 10 is located between the first metal layer M1 and the second metal layer M2, or, please refer to Figure 19 The heating trace 10 is located on a side of the first metal layer M1 facing the first substrate 00 .

[0091] Alternatively, refer to Figure 17 The display panel further includes a semiconductor layer poly, which is located on the side of the first metal layer M1 facing away from the first substrate 00. In some other embodiments of the present invention, the semiconductor layer poly may also be located on the side of the first metal layer M1 facing the substrate. The first metal layer M1 may be, for example, a gate metal layer, and the gate of the transistor T in the display panel may be provided on the first metal layer M1. The source electrode and the drain electrode of the transistor T in the display panel may be located on the second metal layer M2. The semiconductor layer poly includes a source region and a drain region, and the source region and the drain region are formed by doping with type impurity ions or type impurity ions. The source electrode of the transistor T is electrically connected to the source region of the semiconductor layer poly through a contact hole, and the drain electrode of the transistor T is electrically connected to the drain region of the semiconductor layer poly through a contact hole.

[0092] In the display panel provided by the embodiments of the present invention, when the heating trace 10 is disposed between the first metal layer M1 and the second metal layer M2, or when the heating trace 10 is disposed on the side of the first metal layer M1 facing the first substrate 00, the heat generated by the heating trace 10 can be transferred to the liquid crystal in the display panel, thereby achieving a heating function for the liquid crystal in a low-temperature environment. When the heating trace 10 is disposed between the first metal layer M1 and the second metal layer M2, the heating trace 10 is closer to the liquid crystal, and the heat generated by the heating trace 10 is more easily transferred to the liquid crystal, which is more conducive to improving the heating efficiency of the display panel.

[0093] Continue to refer Figure 18 and Figure 19 In an optional embodiment of the present invention, the conductive part 20 is located in the first metal layer M1.

[0094] Specifically, when the conductive part 20 is arranged on the first metal layer M1, the conductive part 20 can be simultaneously manufactured with the signal line on the first metal layer M1, and thus the manufacturing process of the display panel is simplified.

[0095] Figure 20 Fig. 1 shows a relative position relationship diagram of the first metal layer M1, the pixel electrode T1, the data line DL and the heating wire 10 in an embodiment of the present application. Optionally, the first metal layer M1 further includes a light shielding strip 60 electrically connected with the conductive part 20. Please refer to Figure 18 The second substrate 102 includes a black matrix BM, and the black matrix BM defines a plurality of pixel openings. When the first substrate 101 and the second substrate 102 are aligned and attached, the pixel electrode T1 is arranged opposite to the pixel opening. When alignment deviation occurs in the process of aligning the first substrate and the second substrate, a gap can exist between the orthographic projection of the black matrix BM on the first substrate 100 and the orthographic projection of the corresponding pixel electrode T1 on the first substrate 100, and light leakage can occur in the display process. At least part of the orthographic projection of the light shielding strip 60 on the first substrate 100 is located in the periphery of the orthographic projection of the pixel electrode T1 on the first substrate 100. When a gap exists between the orthographic projection of the black matrix BM on the first substrate 100 and the orthographic projection of the pixel electrode T1 on the first substrate 100, the light shielding strip 60 can cover the gap, thereby avoiding the light leakage that can occur when a gap exists between the pixel electrode T1 and the black matrix BM. Therefore, the introduction of the light shielding strip 60 is beneficial to improving the overall display effect of the display panel. Optionally, the light shielding strip 60 and the conductive part 20 are electrically connected, the conductive part 20 is at the same potential as the common electrode, and the light shielding strip 60 overlaps the pixel electrode T1 in the thickness direction of the display panel, which is beneficial to increasing the storage capacitance between the common electrode and the pixel electrode.

[0096] Figure 21 Fig. 2 shows another AA-directional cross-sectional view of the display panel shown in Fig. 1. Please refer to Figure 2 and Figure 17 and Figure 20 In an optional embodiment of the present application, the first substrate further includes a light shielding metal layer M, the light shielding metal layer M is located on the side of the transistor T facing the first substrate 100, the light shielding metal layer M includes a light shielding part 40, and the light shielding part 40 overlaps the active layer poly and the gate of the transistor T in the direction perpendicular to the first substrate 100. The conductive part 20 is located on the light shielding metal layer M.

[0097] When light from the backlight module strikes the transistor T in the first substrate, if the channel region of the transistor T is affected by the light, the performance of the transistor T may be altered or even fail. In this embodiment, the light shielding portion 40 overlaps both the active layer and the gate of the transistor T in a direction perpendicular to the first substrate 00. The overlapping region of the active layer and the gate of the transistor T can be considered the channel of the transistor. In this embodiment, the light shielding portion 40 shields the channel region of the transistor T, preventing light from the backlight module from striking the channel region of the transistor.

[0098] In this embodiment, the conductive portion 20 is disposed on the light-shielding metal layer M. Similarly, there is no need to provide a separate film layer for the conductive portion 20. The conductive portion 20 can be fabricated simultaneously with the light-shielding portion 40 on the light-shielding metal layer M, thereby simplifying the overall display panel manufacturing process. When the conductive portion 20 is disposed on the light-shielding metal layer M, it can provide a light shielding effect. When the abnormal electric field between the heating trace 10 and the common electrode T2 causes abnormal deflection of the liquid crystal, the light from the backlight module cannot be directed to the region of the abnormally deflected liquid crystal due to the light shielding effect of the conductive portion 20, thereby avoiding abnormal display issues visible to the human eye.

[0099] Figure 22 Shown Figure 1 A CC cross-sectional view of the display panel in the embodiment shows another film layer structure of the display area A1 in the display panel.

[0100] In an optional embodiment of the present invention, the first substrate 101 includes a first metal layer M1, a second metal layer M2, and a third metal layer M3. The first metal layer M1, the second metal layer M2, and the third metal layer M3 are all located on the side of the pixel electrode T1 facing the first substrate 00, and the first metal layer M1 is located between the second metal layer M2 and the first substrate 00, and the third metal layer M3 is located between the pixel electrode T1 and the second metal layer M2. The first substrate 101 includes a plurality of transistors T, the gates of the transistors T are located in the first metal layer M1, and the sources or drains of the transistors T are located in the second metal layer M2. The conductive portion 20 is located in the first metal layer M1 or the third metal layer M3. Of course, if there is a suitable film layer between the first metal layer M1 and the second metal layer M2 for setting the conductive portion 20, the conductive portion can also be set between the first metal layer M1 and the second metal layer M2. The present invention is not specifically limited to this.

[0101] Optionally, the display panel further includes a semiconductor layer poly, which is located on the side of the first metal layer M1 facing away from the first substrate 00, or on the side of the first metal layer M1 facing the substrate. The first metal layer M1 may be, for example, a gate metal layer, and the gate of the transistor T in the display panel may be provided on the first metal layer M1. The source electrode and the drain electrode of the transistor T in the display panel may be located on the second metal layer M2, and the semiconductor layer poly includes a source region and a drain region, and the source region and the drain region are formed by doping type impurity ions or type impurity ions. The source electrode of the transistor T is electrically connected to the source region of the semiconductor layer poly through a contact hole, and the drain electrode of the transistor T is electrically connected to the drain region of the semiconductor layer poly through a contact hole. When the display panel includes a third metal layer M3, the third metal layer M3 may be regarded as the film layer where the touch signal line is located.

[0102] When the display panel includes a first metal layer M1, a second metal layer M2, and a third metal layer M3, the conductive portion 20 may be located in any film layer of the first metal layer M1 or the third metal layer M3. Figure 23 The embodiment shown shows a solution of setting the conductive part 20 on the third metal layer M3, wherein, Figure 23 Shown Figure 2 In another AA-direction cross-sectional view, if the heating trace 10 is located on the side of the third metal layer M3 facing the first substrate 00, the conductive portion 20 located in the third metal layer M3 is arranged between the heating trace 10 and the common electrode T2 layer. At this time, the conductive portion 20 can shield the electric field between the heating trace 10 and the common electrode T2 layer, thereby preventing the electric field formed between the common electrode T2 and the heating electrode from causing abnormal deflection of the liquid crystal, thereby avoiding abnormal display problems of the display panel caused by the abnormal deflection of the liquid crystal.

[0103] Figure 24 FIG2 is a top view of a film layer where a common electrode is located in a display panel provided by an embodiment of the present invention. The film layer where the common electrode is located includes a plurality of block-shaped common electrodes T2. Each block-shaped common electrode T2 can be reused as a touch electrode T0. The touch electrode T0 is electrically connected to the touch signal line TL. In the display stage, the touch signal line TL transmits a common voltage signal. In the touch stage, the touch signal line TL transmits a touch signal. The touch signal line TL is located on the side of the pixel electrode T1 close to the first substrate 00. Figure 22 , the touch signal line TL is located in the third metal layer M3.

[0104] Figure 25 The figure shows a top view of the touch signal line and the heating line. Figure 26 for Figure 25 When the common electrode T2 is embodied as follows Figure 24In the block structure shown, adjacent common electrodes T2 are disconnected. To reduce the coupling capacitance between different common electrodes T2 and the touch signal line TL, multiple slits KF are set between the common electrode block and the touch signal line TL. These slits cause the electric field between the heating trace 10 and the other electrodes to pass through the liquid crystal layer. Specifically, in a direction perpendicular to the first substrate 00, the heating trace 10 overlaps with the aforementioned slits KF to form a second region Q2. When the heating trace 10 is introduced into the display panel, if the slits KF between the heating trace 10 and the common electrode T2 overlap, uncontrollable electric fields will be generated between the heating trace 10 and the common electrode T1, and between the heating trace 10 and the pixel electrode T2. For example, please refer to Figure 27 , Figure 27 The figure shows a schematic diagram of generating an uncontrollable electric field between the heating trace and the common electrode, and between the heating trace and the pixel electrode.

[0105] Therefore, in this embodiment, the line segment of the touch signal line that overlaps with the second area is widened. Figure 25 and Figure 26 , wherein the touch signal line TL includes a first portion TL1, and along a direction perpendicular to the first substrate 00, the first portion TL1 covers the second region Q2. At this time, the first portion TL1 in the touch signal line TL can play the role of electric field shielding, avoiding the generation of uncontrollable electric field between the heating trace 10 and the common electrode T2 or the pixel electrode T1, thereby helping to ensure the display effect of the display panel. This embodiment is an improvement for products with touch functions, such as automotive products, etc. When in a low temperature environment, by heating the display panel with a touch function, it can not only ensure the normal display of the display panel, but also help to avoid frostbite of the hands when using the display screen, so it is beneficial to improve the user experience. It should be noted that, Figure 26 The illustrated embodiment only shows a solution of setting the touch signal line TL1 on the side of the pixel electrode T1 facing the first substrate 00, but does not limit the film layer where the touch signal line TL1 is located. In some other embodiments of the present invention, the touch signal line TL1 can also be set between the common electrode T2 and the touch electrode T1.

[0106] Please refer to Figure 23 In an optional embodiment of the present invention, along a direction perpendicular to the first substrate 00 , the conductive portion 20 is located between the heating trace 10 and the pixel electrode T1 , and the conductive portion 20 includes a transparent conductive material.

[0107] When the conductive portion 20 is located between the heating trace 10 and the pixel electrode T1, since the common electrode T2 is located on the side of the pixel electrode T1 facing away from the first substrate 00, the conductive portion 20 is also located between the common electrode T2 and the heating trace 10. The conductive portion 20 is used to shield the electric field formed between the common electrode T2 and the heating trace 10, thereby preventing the electric field between the common electrode T2 and the heating trace 10 from causing liquid crystal deflection and resulting in abnormal display of the display panel. In this embodiment, the conductive portion 20 acts as an electric field shield. When the conductive portion 20 comprises a transparent conductive material, even when the conductive portion 20 is located in the display area A1, the introduction of the conductive portion 20 does not affect the transmittance of the display panel, thereby also helping to ensure the light transmittance of the display panel.

[0108] In an optional embodiment of the present invention, the conductive portion 20 receives a fixed potential signal. Specifically, when the fixed potential signal is provided to the conductive portion 20, the potential on the conductive portion 20 is constant. In this case, the conductive portion 20 can effectively shield the electric field, thereby effectively blocking the electric field formed between the common electrode T2 and the heating trace 10, thereby helping to prevent abnormal deflection of the liquid crystal caused by the electric field.

[0109] In an optional embodiment of the present invention, the conductive part 20 and the common electrode T2 receive the same fixed potential signal. In this case, the conductive part 20 and the common electrode T2 can be connected to the same conductive pad in the display panel. When the conductive pad is electrically connected to the control chip, it is beneficial to reduce the number of conductive pads on the control chip and simplify the structure of the control chip. In addition, the conductive part 20 and the common electrode T2 receive the same fixed potential signal. When the conductive part 20 is set between the heating line 10 and the common electrode T2, it will be impossible to form an electric field between the conductive part 20 and the common electrode T2. Therefore, the electric field between the heating line 10 and the common electrode T2 can be better shielded, thereby avoiding abnormal deflection of the liquid crystal caused by this part of the electric field. When the conductive part and the common electrode are at the same potential, the conductive part and the common electrode can also be connected in parallel, thereby reducing the impedance of the common electrode in parallel.

[0110] Continue to refer Figure 1 In an optional embodiment of the present invention, the display area A1 includes a plurality of pixel rows H arranged along a first direction F1, and the pixel row H includes a plurality of sub-pixels arranged along a second direction F2 (each area corresponding to the pixel electrode T1 corresponds to a sub-pixel); the orthographic projection of the heating trace 10 on the first substrate 00 overlaps with a sub-pixel in a pixel row H.

[0111] Specifically, in the display panel provided by the embodiment of the present invention, the heating lines 10 are arranged corresponding to the sub-pixels in the pixel rows. For example, one heating line 10 corresponds to the sub-pixels in one pixel row. In this way, when the liquid crystal in the display panel is heated by the heating lines 10 in a low-temperature environment, the sub-pixels corresponding to each pixel row are heated by the corresponding heating lines 10, which is beneficial to improving the overall heating uniformity of the display panel.

[0112] Optionally, continue to refer to Figure 1 The display panel also includes a heating bus 50 connected to the heating traces 10. The heating bus 50 is located in the non-display area A2 of the display panel. By providing heating signals to the two heating busses 50 in the non-display area A2 on both sides of the display area A1, the heating signals are transmitted to the heating traces 10 to achieve the heating function of the liquid crystal corresponding to the sub-pixels. Optionally, the heating bus 50 and the heating traces 10 are arranged on the same layer. In this way, the heating bus 50 and the heating traces 10 can be completed in the same film layer and the same process, which helps to improve the production efficiency of the display panel.

[0113] It should be noted that the above embodiment is described with reference to a display panel using LTPS (Low Temperature Poly-silicon) technology, and is also applicable to a display panel using a-Si (amorphous silicon) technology. Figure 28 and Figure 29 ,in, Figure 28 Shown Figure 1 Another CC-direction cross-section of the display panel. Figure 29 Shown Figure 2 Another AA-direction cross-sectional view. In this embodiment, the transistor T is an oxide transistor including an IGZO oxide layer. The gate of the transistor T is located on the first metal layer M1, and the source and drain are located on the second metal layer M2. This embodiment is described by taking the pixel electrode T1 located on the first substrate 101 and the common electrode T2 located on the second substrate 102 as an example, but the position of the common electrode T2 is not limited. In some other embodiments of the present invention, the common electrode T2 may also be located on the first substrate 101.

[0114] When the conductive portion 20 is introduced into the display panel, the conductive portion 20 can be disposed on the first metal layer M1, and the heating trace 10 can be disposed on the side of the conductive portion 20 facing the first substrate 00. In this way, the conductive portion 20 can act as an electric field shield, preventing an abnormal electric field from being generated between the heating trace 10 and the common electrode T2, thereby facilitating the display effect of the display panel.

[0115] Based on the same inventive concept, the present invention also provides a display device, Figure 30Fig. 1 shows a structural schematic diagram of a display device provided by an embodiment of the present application, please refer to Figure 30 The display device 200 comprises the display panel 100 provided by the above-mentioned embodiments of the present application.

[0116] It can be understood that the display device provided by the embodiments of the present application can be a computer, a mobile phone, a tablet computer or other display devices with display function, and the present application does not specifically limit this. The display device provided by the embodiments of the present application has the beneficial effects of the display panel provided by the embodiments of the present application, and specific descriptions can be referred to the specific descriptions of the display panel in the above-mentioned embodiments, which will not be described here.

[0117] As can be seen from the above embodiments, the display panel and the display device provided by the present application at least achieve the following beneficial effects:

[0118] In the display panel and the display device provided by the present application, the common electrode and the plurality of pixel electrodes are arranged on the first substrate, the pixel electrodes are located between the common electrode and the first substrate, and the electric field generated between the pixel electrodes and the common electrode is used to drive the liquid crystal to deflect. The display panel further comprises a plurality of data lines arranged along a first direction and extending along a second direction, and a film layer where the data lines are located is located on a side of the film layer where the pixel electrodes are located towards the first substrate. The orthographic projection of the data line on the first substrate is located between two pixel electrodes arranged along the first direction, and the orthographic projection of the data line on the first substrate and the orthographic projection of the pixel electrode adjacent to the data line on the first substrate have a first interval. When the heating trace is introduced into the display panel, the heating trace and the above-mentioned first interval overlap to form a first area. If the conductive part is not introduced, an electric field will be formed between the heating trace and the common electrode in the above-mentioned first area, which will drive the liquid crystal in the first area and the adjacent area of the first area to abnormally deflect, affecting the display effect. The embodiments of the present application introduce the conductive part in the display panel, and the orthographic projection of the conductive part on the first substrate covers the first area, so as to block the formation of the electric field between the heating trace and the common electrode, or to shield the light emitted by the backlight module from the area where the liquid crystal abnormally deflects, so as to avoid the abnormal deflection phenomenon being recognized by the human eye, thereby being conducive to ensuring the display effect of the display panel when the heating trace is introduced into the display panel.
