Description

Technical Field

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

[0002] With the continuous development of display technologies, the anti-peeping function has gradually become one of the basic functions of current display panels. The implementation methods of the anti-peeping function mainly include external anti-peeping and embedded anti-peeping. Among them, in the existing embedded anti-peeping solutions, a light-shielding structure (such as a black matrix structure, Black Matrix) in the display panel is usually used to block the large-angle display light generated by the light-emitting device, so as to reduce the large-angle display light emitted from the display panel.

[0003] However, the above solutions often require patterning the light-shielding layer in the display panel, which undoubtedly increases the manufacturing process of the display panel, improves the process complexity and manufacturing cost. Summary of the Invention

[0004] In view of this, the present application provides a display panel and a display device.

[0005] In a first aspect, the present application provides a display panel, including a light-emitting device, a plurality of touch electrodes, and a plurality of first light control structures. The first light control structures are located between the film layer where the touch electrodes are located and the light-emitting device; along the direction perpendicular to the plane where the display panel is located, at least part of the first gap overlaps with the second gap, 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 in the same film layer, and the second gap is the gap between two adjacent first light control structures. Wherein, the component of the first light control structure is the same as that of the touch electrode.

[0006] In a second aspect, based on the same inventive concept, the present application provides a display device, including the display panel provided in the first aspect.

[0007] In the present application, compared with other transparent film layers in the display panel, the light transmittance of the first light control structure can also be relatively low. The first light control structure and the touch electrodes 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 electrodes, and the same preparation materials as the touch electrodes, which helps to reduce the preparation difficulty and manufacturing cost of the display panel.

Detailed implementation manners

[0010] 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 accompanying drawings.

[0011] It should be clear that the described embodiments are only some embodiments of the present application, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts belong to the scope of protection of the present application.

[0012] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0013] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0014] It is obvious to those skilled in the art that various modifications and changes can be made in this application without departing from the spirit or scope of this application. Therefore, this application is intended to cover modifications and changes of this application that fall within the scope of the corresponding claims (technical solutions claimed for protection) and their equivalents. It should be noted that the implementation methods provided in the embodiments of this application can be combined with each other without contradiction.

[0015] In the prior art, display panels often rely on two methods to achieve the anti-peeping function, including: external anti-peeping and embedded anti-peeping. External anti-peeping usually chooses to attach an anti-peeping structure on the light-emitting side of the display panel; embedded anti-peeping usually chooses to pattern the light-shielding structure (such as a black matrix structure) in the display panel to block the wide-angle display light generated by the light-emitting device, reduce the wide-angle display light emitted from the display panel, and thus achieve anti-peeping.

[0016] However, in the embedded anti-peeping 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 required. This will undoubtedly increase the preparation process of the display panel, increase the preparation difficulty and preparation cost.

[0017] Figure 1 A schematic diagram of a partial structure of a display panel provided in the present application.

[0018] In view of the above problems, the present application provides a display panel 10, such as 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 the substrate 010, and the light-emitting device 01 can be located in the opening 021 of the 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, so the first organic layer 03 can be used to prevent the light-emitting device 01 from being eroded by external water and oxygen; the first insulating layer 04 can include an inorganic insulating material, such as silicon nitride.

[0019] The display panel 10 further includes a plurality of touch electrodes 05, which can be located on the 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. The display panel 10 can implement a touch function depending on the touch electrodes 05; specifically, during the touch operation on the display panel 10, the display can be performed according to the electrical signals received or fed back by the sensing electrodes and driving electrodes in the display panel 10 to implement the touch function. It should be noted that the touch electrodes 05 can include at least one of molybdenum, titanium, and aluminum. Compared with other transparent film layers in the display panel 10, the light transmittance of the touch electrodes 05 is relatively low.

[0020] Among them, there can be a gap between two adjacent touch electrodes 05 located in the same film layer. To avoid the touch electrodes 05 completely blocking the light-emitting device 01, along the direction perpendicular to the plane where the display panel 10 is located, the gap between the touch electrodes 05 can overlap with the light-emitting device 01, so that 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 screen reaches the expected value.

[0021] The display panel 10 further includes a plurality of first light control structures 06, which are located between the film layer where the touch electrodes 05 are located and the light-emitting device 01. The first light control structures 06 can be disposed on the side of the first insulating layer 04 facing the touch electrodes 05. Correspondingly, to avoid the first light control structures 06 completely blocking the light-emitting device 01, there can also be a gap between two adjacent first light control structures 06 located in the same film layer; and, along the direction perpendicular to the plane where the display panel 10 is located, the gap between the first light control structures 06 can overlap with the light-emitting device 01.

[0022] In a direction perpendicular to the plane where the display panel 10 is located, the first gap 050 and the second gap 060 at least partially overlap, and the overlapping part of the first gap 050 and the second gap 060 overlaps with the light-emitting device 01. The first gap 050 is the gap between two adjacent touch electrodes 05 located in the same film layer, and the second gap 060 is the gap between two adjacent first light control structures 06.

[0023] At this time, among the display light generated by the light-emitting device 01, the display light passing through the part of the first gap 050 that overlaps with the second gap 060 (hereinafter referred to as small-angle display light) can be emitted from the display panel 10 and can be unobstructed by the touch electrode 05 and the first light control structure 06.

[0024] In contrast, for the display light that does not enter the part of the first gap 050 that overlaps with the second gap 060, this part of the display light (hereinafter referred to as large-angle display light) is likely to irradiate the first light control structure 06 or the touch electrode 05, and the process of this large-angle display light irradiating the light-emitting surface of the display panel 10 is likely to be obstructed 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-angle display light and the direction perpendicular to the plane where the display panel 10 is located, the angle between the propagation direction of the above-mentioned small-angle display light and the direction perpendicular to the plane where the display panel 10 is located can be smaller.

[0025] Among them, the component of the first light control structure 06 is the same as that of the touch electrode 05.

[0026] In the embodiment of the present application, since the component of the first light control structure 06 is the same as that of the touch electrode 05, the light transmittance of the first light control structure 06 can also be relatively low compared with other transparent film layers in the display panel 10. At this time, both the first light control structure 06 and the touch electrode 05 can obstruct the propagation process of the above-mentioned large-angle display light, which helps to reduce the large-angle display light emitted from the display panel 10, thereby realizing the anti-peeping function. In addition, the first light control structure 06 can be set by using the preparation equipment, preparation method corresponding to the touch electrode 05 and the same preparation material as the touch electrode 05, which helps to reduce the preparation difficulty and preparation cost of the display panel 10.

[0027] Figure 2 It is a schematic diagram of a partial structure of a display panel provided by the present application.

[0028] In an embodiment of the present application, as Figure 2 shown, the display panel 10 further includes a first film layer 11, and the first film layer 11 is located between the first light control structure 06 and the touch electrode 05. The first film layer 11 may include an insulating material, such as silicon nitride, etc.

[0029] The light transmittance of the first light control structure 06 is less than that of the first film layer 11. It can be understood that the light absorption rate of the first light control structure 06 for the display light is greater than that of the first film layer 11 for the display light, or the light reflectance of the first light control structure 06 for the display light is greater than that of the first film layer 11 for the display light.

[0030] In this embodiment, the presence of the first film layer 11 can create a gap between the touch electrode 05 and the first light control structure 06. The larger this gap is, the larger the distance between the first gap 050 and the second gap 060 in the direction perpendicular to the plane of the display panel 10. It should be noted that if there is display light that 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 of the display panel 10) of this display light needs to meet a certain size. In particular, on the premise that the distance between the light-emitting device 01 and the second gap 060 is fixed, the larger the distance between the first gap 050 and the second gap 060, the smaller the viewing angle required for the display light to pass through the second gap 060 and the first gap 050 in sequence. Therefore, the setting of the first film layer 11 can increase the viewing angle requirement for the display light when it 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.

[0031] In one embodiment of the present application, as Figure 2 shown, the thickness h of the first film layer 11 satisfies: h > 1um.

[0032] In the embodiment of the present application, compared with the case of h ≤ 1um, when h > 1um, the proportion of the large-viewing-angle display light irradiated on the light-blocking structure (the whole 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 method of this embodiment helps to further reduce the large-viewing-angle display light exiting the display panel 10 and improve the anti-peeping effect.

[0033] Figure 3 It is a schematic diagram of a partial structure of a display panel provided by the present application.

[0034] In one embodiment of the present application, as Figure 3 shown, the width of the second gap 060 is greater than the width of the first gap 050.

[0035] In an embodiment of the present application, the first gap 050 may be further away from the light-emitting device 01 than the second gap 060. Considering that the width of the second gap 060 is larger, the (two) first light control structures 06 corresponding to the second gap 060 can be used to obstruct the propagation process of the first type of large-view display light, while the (two) touch electrodes 05 corresponding to the first gap 050 can be used to obstruct the propagation process of the second type of large-view display light. It should be noted that the viewing angle of the first type of large-view display light here is larger than that of the second type of large-view display light. In addition, when preparing the first light control structure 06, an etching process can be adopted, which may specifically include: depositing a metal layer on the side of the first insulating layer 04 away from the light-emitting device 01, and patterning a partial area of the metal layer by using the etching process to obtain the first light control structure 06 and the corresponding second gap 060. Among them, the larger 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 method of this embodiment is beneficial to reducing the preparation difficulty of the first light control structure 06.

[0036] Figure 4 It is a schematic diagram of a partial structure of a display panel provided by the present application.

[0037] In an embodiment of the present application, as Figure 4 shown, among the multiple touch electrodes 05, there are a first electrode 051 and a second electrode 052 arranged in different layers, and at least part of the first electrode 051 is electrically connected to the second electrode 052. The extending direction of the first electrode 051 may intersect with the extending direction of the second electrode 052. In addition, the first electrode 051 can be electrically connected to the second electrode 052 through a through hole 05a.

[0038] Among them, the first electrode 051 is further away from the light-emitting device 01 than the second electrode 052, and the first gap 050 is the gap between two adjacent first electrodes 051.

[0039] To enable the action range of the touch electrode 05 to cover the display area of the display panel 10, the touch electrode 05 can be selected to extend in different directions; at the same time, to avoid the short circuit of the touch electrode 05 with other devices, some touch electrodes 05 with different-layer distribution and electrical connection can be set. At this time, by selecting to set the first electrode 051 on the side of the second electrode 052 away from the first light control structure 06, it helps to have a certain distance between the first gap 050 and the second gap 060, further reducing the large-view display light emitted from the display panel 10.

[0040] In an embodiment of the present application, the first electrode 051 includes a black metal.

[0041] In the embodiment of the present application, compared with other metal materials, ferrous metals have a relatively strong absorption ability for visible light. By using ferrous metals to prepare the first electrode 051 in this embodiment, it helps the first electrode 051 to have a strong absorption ability for ambient light, reduce the reflection degree of the display panel 10 to ambient light, and improve the display effect. In particular, when the polarizer structure is not provided on the display panel 10, adopting the solution of this embodiment helps to weaken the intensity of the reflected light on the display panel 10.

[0042] In an embodiment of the present application, as Figure 1 shown, along the direction perpendicular to the plane where the display panel 10 is located, the touch electrode 05 and the first light control structure 06 at least partially overlap.

[0043] In this embodiment, when there is large-angle display light irradiating on the overlapping part of the first light control structure 06 and the touch electrode 05, if the large-angle display light can pass through the first light control structure 06, the probability that the large-angle display light irradiates on the touch electrode 05 is relatively large. This means that the large-angle display light is blocked by the first light control structure 06 and the touch electrode 05 successively during the propagation process, so the light intensity corresponding to the large-angle display light when it exits the display panel 10 can be relatively weak, or the large-angle display light cannot exit the display panel 10.

[0044] 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.

[0045] 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 likely to exist between the first light control structure 06 and the touch electrode 05, and there is a possibility of mutual crosstalk between them. Therefore, to avoid the above crosstalk, this 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, to avoid the appearance of a potential difference between the first light control structure 06 and the touch electrode 05, and to prevent the first light control structure 06 from interfering with the working state of the touch electrode 05.

[0046] In an embodiment of the present application, the first light control structure 06 receives a ground signal.

[0047] In the embodiment of the present application, the first light control structure 06 is grounded, which means that the potential magnitude corresponding to the first light control structure 06 can be constant. 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 hardly interfered by the first light control structure 06.

[0048] In a possible implementation, the first light control structure 06 may not receive an electrical signal.

[0049] Figure 5 A schematic diagram of a partial structure of a display panel provided in the present application, Figure 6 for Figure 5 The projection diagram of part of the structure of the display panel shown is for easy understanding. Figure 6 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.

[0050] In one embodiment of the present application, Figure 5 As shown, the display panel 10 further includes a second film layer 12, which is located on a side of the first light control structure 06 close to the touch electrode 05. The touch electrode 05 can be prepared on a surface of the second film layer 12 away from the first light control structure 06.

[0051] The surface of the second film layer 12 away from the light emitting device 01 includes a protrusion 121. For a portion of the film layer located on the side of the second film layer 12 away from the light emitting device 01, the portion of the film layer overlapping with the protrusion 121 may have undulations in a direction perpendicular to the plane where the display panel 10 is located, thereby generating a step difference. Figure 5 and Figure 6 The orthographic projection 121 a of the protrusion 121 at least partially surrounds the orthographic projection 01 a of the light-emitting device 01 .

[0052] 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 the light transmittance of the second film layer 12. The second light control structure 07 may have a greater light absorptivity or a greater light reflectivity relative to the second film layer 12. After the display light generated by the light emitting device 01 is irradiated onto the second light control structure 07, it is difficult for the part of the display light to pass through the second light control structure 07 and exit the display panel 10.

[0053] 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. Figure 6 As shown, the portion of the second light control structure 07 conformally attached to the protrusion 121 may extend in a direction perpendicular to the plane where the display panel 10 is located. This portion may be regarded as a retaining wall structure, which may further prevent the wide-viewing angle display light from emitting from the display panel 10 .

[0054] In one embodiment of the present application, Figure 5 As shown, the second light control structure 07 is disposed in the same layer as at least a portion of the touch electrode 05 , and the components of the second light control structure 07 are the same as those of the touch electrode 05 .

[0055] In this embodiment, considering that the second light control structure 07 and the touch electrode 05 have the same components and are arranged in the same layer, in the actual manufacturing process, the second light control structure 07 and the touch electrode 05 can be manufactured in the same manufacturing step, which helps to reduce the process steps and the manufacturing cost.

[0056] In an embodiment of the present application, as Figure 5 shown, the closer to the light-emitting device 01, the larger the width w of the protrusion 121.

[0057] In an embodiment of the present application, the cross-section of the protrusion 121 can be regarded as a shape that is narrow at the top and wide at the bottom. During the manufacturing process, the manufacturing difficulty corresponding to the protrusion 121 with this cross-sectional shape is relatively low, which helps to reduce the manufacturing cost.

[0058] Figure 7 is a schematic diagram of a partial structure of a display panel provided by the present application, Figure 8 is a schematic diagram of a partial structure of a display panel provided by the present application.

[0059] In a possible implementation manner, in combination with Figure 6 、 Figure 7 and Figure 8 , the cross-sectional shape of the protrusion 121 can be semicircular, trapezoidal, triangular, etc.

[0060] Figure 9 is a schematic diagram of a partial structure of a display panel provided by the present application.

[0061] In an embodiment of the present application, as Figure 9 shown, the closer to the light-emitting device 01, the smaller the width w of the protrusion 121.

[0062] In an embodiment of the present application, the width w of the protrusion 121 satisfies: w ≤ 6um.

[0063] In an embodiment of the present application, the width w of the protrusion 121 can affect the area of the surface of the protrusion 121 far from the light-emitting device 01. When the height of the protrusion 121 is fixed, the larger the width w, the larger the area of the surface of the protrusion 121 far from the light-emitting device 01. Considering that the second light control structure 07 can be covered on the surface of the protrusion 121 far from the light-emitting device 01, in order to prevent the coverage area of the second light control structure 07 from being too large and hindering 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 in the present application, it helps to reduce the large-angle display light emitted from the display panel 10 while preventing the second light control structure 07 from hindering the normal light emission of the display panel 10.

[0064] In an embodiment of the present application, the height h of the protrusion 121 satisfies: h > 3um.

[0065] In the embodiment of the present application, the size of the height h of the protrusion 121 can affect the amount of light of the large-angle display light that the second light control structure 07 can block. The larger 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 of the display panel 10, the larger the viewing angle range corresponding to the display light irradiated onto the second light control structure 07, and thus the greater the amount of light of the display light irradiated onto the second light control structure 07. Therefore, in this embodiment, by setting h>3um, it helps to use the second light control structure 07 to reduce the large-angle display light emitted from the display panel 10 and improve the anti-peeping performance.

[0066] Figure 10 It is a schematic diagram of a partial structure of a display panel provided by the present application.

[0067] In an embodiment of the present application, as Figure 10 shown, the display panel 10 further includes a microlens structure 08, and the microlens structure 08 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 relatively high.

[0068] The microlens structure 08 overlaps with the light-emitting device 01 in the direction perpendicular to the plane of the display panel 10, so that part of the display light generated by the light-emitting device 01 can enter the microlens structure 08 and be emitted from the surface of the microlens structure 08 away from the light-emitting device 01.

[0069] The surface of the microlens structure 08 away from the light-emitting device 01 may include a first surface 081 and a second surface 082, and the tangent of the first surface 081 may intersect with the plane of the display panel 10.

[0070] The refractive index of the microlens structure 08 is greater than the refractive index of the contact medium 09, and the contact medium 09 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 a partial film layer structure in the display panel 10. Since the refractive index of the contact medium 09 is different from the refractive index of the microlens structure 08, in the process of the display light passing through the first surface 081 and entering the contact medium 09, this part of the display light is prone to refraction.

[0071] Wherein, the side angle θ is an obtuse angle and the opening corresponding to the side angle θ faces away from the microlens structure 08, and the side angle θ is the angle between the first surface 081 and the plane of the display panel 10.

[0072] In the embodiment of the present application, since the microlens structure 08 can overlap with the light-emitting device 01, the viewing angle corresponding to the display light emitted through the microlens structure 08 can be relatively small. In particular, the propagation direction of this part of the display light (hereinafter referred to as the vertical display light) in the display panel 10 can be perpendicular to the plane where the display panel 10 is located. During the process of the vertical display light passing through the first surface 081, based on the law of refraction, it can be found that the propagation direction of the vertical display light is inclined towards the direction of the second surface 082. Therefore, when there is large-view display light entering the contact medium 09 after passing through the first surface 081, the large-view display light can be inclined towards the direction of the second surface 082 after exiting the microlens structure 08. At this time, its corresponding viewing angle becomes smaller accordingly. It can be seen from this that the microlens structure 08 provided in this embodiment can change the propagation direction of part of the large-view display light, thereby reducing the large-view display light emitted from the display panel 10 and improving the anti-peeping performance.

[0073] In a possible implementation manner, the second surface 082 can be parallel to the plane where the display panel 10 is located.

[0075] The present application provides a display device 20, as Figure 11 shown, the display device 20 includes the display panel 10 provided in the above embodiment. The display device 20 can be a mobile phone. In addition, the display device 20 can also be an electronic device such as a computer or a television.

[0076] The display panel 10 in the display device 20 provided in the embodiment of the present application can achieve the anti-peeping function without a light-shielding layer.

[0077] For the same and similar parts among the various embodiments in this specification, reference can be made to each other. In particular, for the device embodiments and the terminal embodiments, since they are basically similar to the method embodiments, the description is relatively simple, and for the relevant parts, reference can be made to the description in the method embodiments.
