TECHNICAL FIELD
[0001] The present application relates to the technical field of display, in particular to a display panel and a display device. BACKGROUND
[0002] With the continuous development of display technology, the anti-peeping function gradually becomes one of the basic functions of the current display panel. The implementation methods of the anti-peeping function mainly include external anti-peeping and embedded anti-peeping. In the existing embedded anti-peeping scheme, the large-angle display light generated by the light emitting device is usually shielded by the light shielding structure (such as the black matrix structure) in the display panel to reduce the large-angle display light emitted from the display panel.
[0003] However, the above scheme often needs to pattern the light shielding layer in the display panel, which undoubtedly increases the preparation process of the display panel and improves the process complexity and preparation cost. SUMMARY
[0004] Therefore, the present application provides a display panel and a display device.
[0005] In a first aspect, the present application provides a display panel, comprising a light emitting device, a plurality of touch electrodes and a plurality of first light control structures. The first light control structure is located between the film layer where the touch electrode is located and the light emitting device; along the direction perpendicular to the plane where the display panel is located, the first gap and the second gap at least partially overlap, and the overlapping part of the first gap and the second gap overlaps with the light emitting device; the first gap is the gap between two adjacent touch electrodes located in the same film layer, and the second gap is the gap between two adjacent first light control structures.
[0006] The component of the first light control structure is the same as the component of the touch electrode.
[0007] In a second aspect, based on the same inventive concept, the present application provides a display device comprising the display panel provided in the first aspect.
[0008] In the present application, the light transmittance of the first light control structure can also be low relative to other transparent film layers in the display panel, and the first light control structure and the touch electrode can both hinder the propagation process of the large-angle display light, which helps to reduce the large-angle display light emitted from the display panel, and thus realizes the anti-peeping function. In addition, the preparation of the first light control structure can be realized by using the preparation equipment, preparation method corresponding to the touch electrode and the same preparation material as the touch electrode, which helps to reduce the preparation difficulty and preparation cost of the display panel.

[0021] In order to better understand the technical solutions of the present application, the embodiments of the present application will be described in detail below with reference to the drawings.
[0022] It should be noted that the described embodiments are merely some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.
[0023] The terms used in the embodiments of the present application are merely for the purpose of describing the specific embodiments, and are not intended to limit the present application.

In addition, the character " / " in this paper generally represents that the front and rear associated objects are in an "or" relationship.
[0025] Various modifications and changes can be made to the present application without departing from the spirit or scope of the present application, which will be apparent to those skilled in the art. Therefore, the present application is intended to cover the modifications and variations of the present application falling within the scope of the corresponding claims (claimed technical solutions) and their equivalents. It should be noted that the embodiments provided by the embodiments of the present application can be combined with each other without contradiction.
[0026] In the prior art, display panels often rely on two ways to achieve the function of preventing peeping, including: externally hanging type and embedded type. The externally hanging type usually chooses to attach a peep-proof structure on the light-emitting side of the display panel; the embedded type usually chooses to patternize the light-shielding structure (such as the black matrix structure) in the display panel to shield the large-angle display light generated by the light-emitting device, reduce the large-angle display light emitted from the display panel, and thus achieve the function of preventing peeping.
[0027] However, in the embedded type peep-proof process, additional light-shielding materials (for preparing the above-mentioned light-shielding structure), related preparation equipment (including equipment for evaporating the above-mentioned light-shielding materials and patterning the light-shielding structure) and corresponding process steps are needed. This will undoubtedly increase the preparation process of the display panel, and increase the preparation difficulty and cost.
[0028] Figure 1 A schematic diagram of a part of a structure of a display panel provided by the present application is shown.
[0029] To solve the above problems, the present application provides a display panel 10, as shown in Figure 1As shown, the display panel 10 includes a light-emitting device 01, which can be an Organic Light-Emitting Diode. The light-emitting device 01 can include a first electrode 011 (which can be an anode), a light-emitting layer 012, and a second electrode 013 (which can be a cathode) stacked in sequence. The first electrode 011 can be located on one side of a substrate 010, and the light-emitting device 01 can be located in an opening 021 of a pixel definition layer 02. The display panel 10 can further include a first organic layer 03 and a first insulating layer 04. The first organic layer 03 can be located between the first insulating layer 04 and the light-emitting device 01. The first organic layer 03 can include an organic material, and the first organic layer 03 can be used to impede the erosion of the light-emitting device 01 by external water and oxygen. The first insulating layer 04 can include an inorganic insulating material, such as silicon nitride.
[0030] The display panel 10 further includes a plurality of touch electrodes 05, which can be located on a side of the first insulating layer 04 away from the light-emitting device 01. The plurality of touch electrodes 05 can include sensing electrodes and driving electrodes, and the display panel 10 can rely on the touch electrodes 05 to achieve a touch function. Specifically, during a touch operation on the display panel 10, the display panel 10 can display electrical signals received or fed back by the sensing electrodes and the driving electrodes, respectively, to achieve the touch function. It should be noted that the touch electrodes 05 can include at least one of molybdenum, titanium, and aluminum. The light transmittance of the touch electrodes 05 is relatively low relative to other transparent film layers in the display panel 10.
[0031] Among the plurality of touch electrodes 05, adjacent two touch electrodes 05 located in the same film layer can have a gap. To avoid the touch electrodes 05 completely blocking the light-emitting device 01, the gap between the touch electrodes 05 can overlap the light-emitting device 01 in a direction perpendicular to the plane on which the display panel 10 is located. Thus, part of the display light generated by the light-emitting device 01 can pass through the gap between the touch electrodes 05, thereby ensuring that the brightness of the display image reaches an expected value.
[0032] The display panel 10 further includes a plurality of first light control structures 06, which are located between the film layer on which the touch electrodes 05 are located and the light-emitting device 01. The first light control structures 06 can be disposed on a side of the first insulating layer 04 facing the touch electrodes 05. Accordingly, to avoid the first light control structures 06 completely blocking the light-emitting device 01, adjacent two first light control structures 06 located in the same film layer can also have a gap. Furthermore, the gap between the first light control structures 06 can overlap the light-emitting device 01 in a direction perpendicular to the plane on which the display panel 10 is located.
[0033] The first gap 050 and the second gap 060 at least partially overlap in a direction perpendicular to a plane on which the display panel 10 is located, and the portion where the first gap 050 and the second gap 060 overlap each other overlaps the light-emitting device 01. The first gap 050 is a gap between two adjacent touch electrodes 05 in the same film layer, and the second gap 060 is a gap between two adjacent first light control structures 06.
[0034] At this time, among the display light generated by the light-emitting device 01, the display light (hereinafter referred to as small viewing angle display light) that passes through the portion of the first gap 050 that overlaps the second gap 060 can be emitted out of the display panel 10 and can not be hindered by the touch electrode 05 and the first light control structure 06.
[0035] In contrast, for the display light that does not enter the portion of the first gap 050 that overlaps the second gap 060, the portion of the display light (hereinafter referred to as large viewing angle display light) is easily irradiated to the first light control structure 06 or the touch electrode 05, and then the process of the large viewing angle display light irradiating to the light-emitting surface of the display panel 10 is easily hindered by the first light control structure 06 and the touch electrode 05. It should be noted that, relative to the angle between the propagation direction of the above-mentioned large viewing angle display light and the direction perpendicular to the plane on which the display panel 10 is located, the angle between the propagation direction of the above-mentioned small viewing angle display light and the direction perpendicular to the plane on which the display panel 10 is located can be smaller.
[0036] The first light control structure 06 and the touch electrode 05 are made of the same material.
[0037] In the embodiments of the present application, since the first light control structure 06 and the touch electrode 05 are made of the same material, the light transmittance of the first light control structure 06 can also be lower relative to other transparent film layers in the display panel 10. At this time, the first light control structure 06 and the touch electrode 05 can both hinder the propagation process of the above-mentioned large viewing angle display light, which helps to reduce the large viewing angle display light emitted out of the display panel 10, and thus the privacy function is realized. In addition, the first light control structure 06 can be set by using the preparation equipment, preparation method and preparation material corresponding to the touch electrode 05, which helps to reduce the preparation difficulty and preparation cost of the display panel 10.
[0038] Figure 2 A schematic diagram of a part of a display panel provided in the present application is shown.
[0039] In an embodiment of the present application, as shown in Figure 2 The display panel 10 further includes a first film layer 11 between the first light control structure 06 and the touch electrode 05. The first film layer 11 can include an insulating material, such as silicon nitride, etc.
[0040] The light transmittance of the first light control structure 06 is less than the light transmittance of the first film layer 11, which can be understood as that the light absorption rate of the first light control structure 06 to the display light is greater than the light absorption rate of the first film layer 11 to the display light, or the light reflection rate of the first light control structure 06 to the display light is greater than the light reflection rate of the first film layer 11 to the display light.
[0041] In the embodiment, the presence of the first film layer 11 can cause a gap between the touch electrode 05 and the first light control structure 06, and the greater the gap, the greater the distance between the first gap 050 and the second gap 060 in the direction perpendicular to the plane where the display panel 10 is located. It should be noted that if the display light can pass through the second gap 060 and the first gap 050, the viewing angle (the angle between the propagation direction and the direction perpendicular to the plane where the display panel 10 is located) of the display light needs to meet a certain size. In particular, under the premise that the distance between the light emitting device 01 and the second gap 060 is fixed, the greater the distance between the first gap 050 and the second gap 060, the smaller the viewing angle required when the display light passes through the second gap 060 and the first gap 050 in turn. Therefore, the setting of the first film layer 11 can improve the viewing angle requirement when the display light exits the display panel, so that only the display light with a viewing angle less than a certain threshold can pass through the second gap 060 and the first gap 050.
[0042] In an embodiment of the present application, as shown in Figure 2 The thickness h of the first film layer 11 satisfies: h>1um.
[0043] In the embodiment of the present application, compared with the case of h≤1um, when h>1um, the proportion of the display light with a large viewing angle irradiated on the light blocking structure (including the whole structure composed of the first light control structure 06 and the touch electrode 05) in the display light generated by the light emitting device 01 is higher. Therefore, the setting mode of the embodiment is helpful to further reduce the display light with a large viewing angle exiting the display panel 10 and improve the peep-proof effect.
[0044] Figure 3 A schematic diagram of a part of the structure of a display panel provided in the present application.
[0045] In an embodiment of the present application, as shown in Figure 3 The width of the second gap 060 is greater than the width of the first gap 050.
[0046] In the embodiment of the present application, the first gap 050 can be farther away from the light emitting device 01 relative to the second gap 060. Considering that the width of the second gap 060 is greater, the first light control structure 06 (two) corresponding to the second gap 060 can be used to hinder the propagation process of the first type of large viewing angle display light, and the touch electrode 05 (two) corresponding to the first gap 050 can be used to hinder the propagation process of the second type of large viewing angle display light. It should be noted that the viewing angle of the first type of large viewing angle display light is greater than that of the second type of large viewing angle display light. In addition, an etching process can be used in the preparation of the first light control structure 06, which can specifically include: evaporating a metal layer on the side of the first insulating layer 04 away from the light emitting device 01, and patterning part of the metal layer by using an etching process to obtain the first light control structure 06 and the corresponding second gap 060. The greater the width of the second gap 060, the lower the etching precision requirement for the metal layer, and the smaller the preparation difficulty of the first light control structure 06. Therefore, the setting mode of the present application is beneficial to reduce the preparation difficulty of the first light control structure 06.
[0047] Figure 4 A schematic diagram of a partial structure of a display panel provided in the present application.
[0048] In an embodiment of the present application, as shown in Figure 4 The first electrode 051 and the second electrode 052 are arranged in different layers, and at least part of the first electrode 051 is electrically connected to the second electrode 052. The extension direction of the first electrode 051 can intersect the extension direction of the second electrode 052, and in addition, the first electrode 051 can be electrically connected to the second electrode 052 through the via hole 05a.
[0049] Among them, relative to the second electrode 052, the first electrode 051 is farther away from the light emitting device 01, and the first gap 050 is the gap between two adjacent first electrodes 051.
[0050] In order to realize that the effective range of the touch electrode 05 can cover the display area of the display panel 10, the touch electrode 05 can be arranged to extend in different directions; at the same time, in order to avoid the short circuit between the touch electrode 05 and other devices, part of the touch electrode 05 can be arranged to be distributed in different layers and electrically connected. At this time, by selecting the first electrode 051 to be located on the side of the second electrode 052 away from the first light control structure 06, it is helpful to make there be a certain distance between the first gap 050 and the second gap 060, and further reduce the large viewing angle display light emitted from the display panel 10.
[0051] In an embodiment of the present application, the first electrode 051 comprises a black metal.
[0052] In the embodiment of the present application, the black metal has a stronger absorption capacity for visible light than other metal materials. The first electrode 051 is prepared by using the black metal, which helps to make the first electrode 051 have a stronger absorption capacity for ambient light, reduces the reflection degree of ambient light on the display panel 10, and improves the display effect. In particular, when no polarizing plate structure is arranged on the display panel 10, the scheme of the present embodiment helps to weaken the reflected light intensity on the display panel 10.
[0053] In an embodiment of the present application, as shown in Figure 1 The touch electrode 05 and the first light control structure 06 at least partially overlap in the direction perpendicular to the plane on which the display panel 10 is located.
[0054] In the embodiment, when the large viewing angle display light irradiates the part of the first light control structure 06 that overlaps with the touch electrode 05, if the large viewing angle display light can pass through the first light control structure 06, the probability of the large viewing angle display light irradiating the touch electrode 05 is larger. This means that the large viewing angle display light is hindered by the first light control structure 06 and the touch electrode 05 in turn during propagation, so that the corresponding light intensity of the large viewing angle display light when it exits the display panel 10 can be weaker, or the large viewing angle display light cannot exit the display panel 10.
[0055] In an embodiment of the present application, the first light control structure 06 receives an electrical signal, and the voltage of the electrical signal received by the first light control structure 06 is the same as the voltage of the electrical signal received by the touch electrode 05.
[0056] Since the first light control structure 06 can receive an electrical signal, considering that the touch electrode 05 and the first light control structure 06 can overlap, an electric field is easily generated between the first light control structure 06 and the touch electrode 05, and mutual crosstalk between them is possible. Therefore, to avoid the above-mentioned crosstalk, the present embodiment sets the voltage of the electrical signal received by the first light control structure 06 to be the same as the voltage of the electrical signal received by the touch electrode 05, so as to avoid the potential difference between the first light control structure 06 and the touch electrode 05, and prevent the first light control structure 06 from interfering with the working state of the touch electrode 05.
[0057] In an embodiment of the present application, the first light control structure 06 receives a ground signal.
[0058] In the embodiment of the present application, the first light control structure 06 receives a ground signal, which means that the potential of the first light control structure 06 can be constant, and even if there is a potential difference between the touch electrode 05 and the first light control structure 06, the electrical signal on the touch electrode 05 is difficult to be interfered by the first light control structure 06.
[0059] In a possible implementation, the first light control structure 06 can also not receive the electrical signal.
[0060] Figure 5 A schematic diagram of a partial structure of a display panel is provided in the present application, Figure 6 A schematic diagram of a partial structure of a display panel is provided in the present application, Figure 5 A schematic diagram of a partial structure of a display panel is provided in the present application, Figure 6 In the present application, only the positional relationship between the orthographic projection of the protrusion on the substrate and the orthographic projection of the light emitting device on the substrate is shown.
[0061] In an embodiment of the present application, as shown in Figure 5 The display panel 10 further includes a second film layer 12, which is located on the side of the first light control structure 06 close to the touch electrode 05. The touch electrode 05 can be prepared on the surface of the second film layer 12 away from the first light control structure 06.
[0062] The surface of the second film layer 12 away from the light emitting device 01 includes a protrusion 121. For the part of the second film layer 12 on the side away from the light emitting device 01, the part of the film layer overlapping the protrusion 121 can appear undulating in the direction perpendicular to the plane of the display panel 10, resulting in a step difference. In combination with Figure 5 and Figure 6 The orthographic projection 121a of the protrusion 121 at least partially surrounds the orthographic projection 01a of the light emitting device 01.
[0063] The display panel 10 further includes a second light control structure 07, and the light transmittance of the second light control structure 07 is less than that of the second film layer 12. The second light control structure 07 can have a greater light absorption rate or a greater light reflectivity relative to the second film layer 12. Wherein, after the display light generated by the light emitting device 01 irradiates on the second light control structure 07, the part of the display light is difficult to pass through the second light control structure 07 and exit the display panel 10.
[0064] At least part of the second light control structure 07 is conformally attached to the surface of the protrusion 121 away from the light emitting device 01. As shown in Figure 6 The part of the second light control structure 07 conformally attached to the protrusion 121 can extend in the direction perpendicular to the plane of the display panel 10, which can be regarded as a barrier structure and can further hinder the display light of large viewing angle from exiting the display panel 10.
[0065] In an embodiment of the present application, as shown in Figure 5 The second light control structure 07 is disposed in the same layer as at least part of the touch electrode 05, and the composition of the second light control structure 07 is the same as that of the touch electrode 05.
[0066] In the embodiment, considering that the second light control structure 07 is the same as and arranged in the same layer as the touch electrode 05, the second light control structure 07 and the touch electrode 05 can be prepared in the same preparation step in the actual preparation process, which helps to reduce the process steps and reduce the preparation cost.
[0067] In an embodiment of the present application, as shown in Figure 5 , the closer to the light emitting device 01, the greater the width w of the protrusion 121.
[0068] In the embodiment of the present application, the cross section of the protrusion 121 can be considered as a shape of narrow at the top and wide at the bottom. In the preparation process, the protrusion 121 with the cross section shape has a lower preparation difficulty, which helps to reduce the preparation cost.
[0069] Figure 7 A schematic diagram of a partial structure of a display panel provided by the present application is shown in Figure 8 A schematic diagram of a partial structure of a display panel provided by the present application is shown in
[0070] In a possible implementation, in combination with Figure 6 , Figure 7 and Figure 8 , the cross section shape of the protrusion 121 can be semicircular, trapezoidal, triangular, etc.
[0071] Figure 9 A schematic diagram of a partial structure of a display panel provided by the present application is shown in
[0072] In an embodiment of the present application, as shown in Figure 9 , the closer to the light emitting device 01, the smaller the width w of the protrusion 121.
[0073] In an embodiment of the present application, the width w of the protrusion 121 satisfies: w≤6um.
[0074] In the embodiment of the present application, the width w of the protrusion 121 can affect the area size of the protrusion 121 away from the surface of the light emitting device 01. When the height of the protrusion 121 is fixed, the greater the width w, the greater the area of the protrusion 121 away from the surface of the light emitting device 01. Considering that the protrusion 121 can cover the second light control structure 07 away from the surface of the light emitting device 01, in order to avoid that the second light control structure 07 has an excessively large coverage area and hinders the normal light emission of the display panel 10, it is necessary to limit the width w of the protrusion 121 within a suitable range. That is, by setting w≤6um, the present application helps to reduce the display light of a large viewing angle emitted from the display panel 10 while avoiding that the second light control structure 07 hinders the normal light emission of the display panel 10.
[0075] In an embodiment of the present application, the height h of the protrusion 121 satisfies: h>3um.
[0076] In the embodiment of the present application, the size of the height h of the protrusion 121 can affect the light quantity of the large-view-angle display light that can be hindered by the second light control structure 07. The greater the height h of the protrusion 121, the greater the extension length of the second light control structure 07 in the direction perpendicular to the plane where the display panel 10 is located, and the greater the range of the view angle corresponding to the display light irradiated onto the second light control structure 07, and the greater the light quantity of the display light irradiated onto the second light control structure 07. Therefore, by setting h>3um, the embodiment helps to reduce the large-view-angle display light emitted from the display panel 10 by using the second light control structure 07, and improves the peep-proof performance.
[0077] Figure 10 A schematic diagram of a partial structure of a display panel provided in the present application.
[0078] In one embodiment of the present application, as shown in Figure 10 The display panel 10 further includes a microlens structure 08, which is located on the side of the touch electrode 05 away from the light emitting device 01. The microlens structure 08 can be a transparent structure, that is, the light transmittance of the microlens structure 08 to the display light can be high.
[0079] The microlens structure 08 and the light emitting device 01 overlap in the direction perpendicular to the plane where the display panel 10 is located, and thus part of the display light generated by the light emitting device 01 can enter the microlens structure 08 and be emitted out of the microlens structure 08 by the surface of the microlens structure 08 away from the light emitting device 01.
[0080] The surface of the microlens structure 08 away from the light emitting device 01 can include a first surface 081 and a second surface 082, and the tangent of the first surface 081 can intersect the plane where the display panel 10 is located.
[0081] The light refractive index of the microlens structure 08 is greater than the light refractive index of the contact medium 09, which is the medium in contact with the first surface 081 of the microlens structure 08 away from the light emitting device 01. The contact medium 09 can be air or part of the film layer structure in the display panel 10. Since the light refractive index of the contact medium 09 is different from the light refractive index of the microlens structure 08, part of the display light is easily refracted in the process of passing through the first surface 081 and entering the contact medium 09.
[0082] Wherein the side angle θ is an obtuse angle and the side angle θ corresponds to the opening of the microlens structure 08, and the side angle θ is the angle between the first surface 081 and the plane where the display panel 10 is located.
[0083] In the embodiment of the present application, since the microlens structure 08 can overlap with the light emitting device 01, the size of the viewing angle corresponding to the display light emitted by the microlens structure 08 can be small, in particular, the propagation direction of the part of display light (hereinafter referred to as vertical display light) in the display panel 10 can be perpendicular to the plane where the display panel 10 is located. In the process of the vertical display light passing through the first surface 081, based on the refraction law, it can be found that the propagation direction of the vertical display light is inclined to the direction of the second surface 082. Therefore, when there is a large viewing angle display light passing through the first surface 081 and then entering the contact medium 09, the large viewing angle display light can be inclined to the direction of the second surface 082 after being emitted from the microlens structure 08, at this time, the corresponding viewing angle is correspondingly reduced. Therefore, the microlens structure 08 provided in the embodiment can change the propagation direction of part of the large viewing angle display light, thereby reducing the large viewing angle display light emitted from the display panel 10, and improving the peep-proof performance.
[0084] In a possible implementation, the second surface 082 can be parallel to the plane where the display panel 10 is located.

[0087] The display panel 10 in the display device 20 provided in the embodiment of the present application can realize the peep-proof function without the light shielding layer.
