Description

TECHNICAL FIELD

[0001] The present disclosure generally relates to the technical field of display device, and in particular, to a display panel and a display device. BACKGROUND

[0002] With the continuous development of display technology, the display mode of the display panel is also constantly enriched.

[0003] In order to enhance the display effect and improve the user experience, a single crystal silicon-based circle can be used as a driving backboard of the display panel. In related technologies, in order to enhance the display brightness, a lens layer is added on the side of the pixel layer away from the substrate of the display panel. The microlens in the lens layer is in a hemispherical shape. Since the hemispherical microlens has the technical effect of light condensation, it can help to greatly improve the display brightness of the pixel during the display process.

[0004] The premise of improving the display brightness of the display panel by the lens is that the shape of each lens in the lens layer is consistent with the preset requirement, for example, the height of the lens, the side wall angle of the lens, etc. all need to be consistent with the preset requirement. Based on this, in order to ensure accurate enhancement of display brightness, the shape of the lens needs to be detected comprehensively during factory detection. However, since the microlens is a transparent structure, its height parameter and side wall angle parameter are not easy to obtain in practice, so the detection process is difficult. UTILITY MODEL CONTENT

[0005] In view of the above defects or shortcomings in the related art, it is desirable to provide a display panel and a display device, which can solve the problem that the detection process is difficult due to the transparent structure of the lens, the height parameter and the side wall angle parameter are not easy to obtain in practice, and greatly improve the positioning accuracy and detection efficiency of the lens.

[0006] In a first aspect, a display panel is provided, the display panel comprising a pixel layer and a lens layer disposed opposite the pixel layer in a direction of orthographic projection;

[0007] In a non-display region of the display panel, a plurality of positioning structures are disposed on a first film layer and / or a second film layer of a side of the lens layer close to a substrate of the display panel, the first film layer being an adjacent film layer of the lens layer, and the second film layer being a spacing film layer of the lens layer;

[0008] The lens layer comprises a plurality of lenses, and at least one lens is disposed in an arrangement direction of any two positioning structures in the plurality of positioning structures, and the arrangement direction of the any two positioning structures overlaps with a center of each lens in the at least one lens

[0009] In the present application, the display panel includes a pixel layer and a lens layer arranged opposite to the pixel layer in the orthographic projection direction; in the non-display area of the display panel, a plurality of positioning structures are arranged on the first film layer adjacent to the lens layer and / or the second film layer spaced from the lens layer on the side of the lens layer close to the display panel substrate; the lens layer includes a plurality of lenses, and at least one lens is arranged in the arrangement direction of any two positioning structures in the plurality of positioning structures, and the arrangement direction of any two positioning structures overlaps the center of each lens in the at least one lens. In this way, by arranging a plurality of positioning structures for positioning the center position of the lens in the non-display area, the center position of the lens can be determined based on the positioning structure in the subsequent process of determining the morphological parameters of the lens, and then the key morphological parameters of the lens, such as the height parameter and the side wall angle parameter, can be determined based on the center position, thereby greatly improving the accuracy and efficiency of detecting the morphological parameters of the lens.

[0010] In a second aspect, a display device is provided, which includes the display panel of the first aspect.

[0026] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] With the continuous development of display panels, the brightness requirements for display panels are constantly increasing in many scenarios. For example, in VR or AR scenarios, display panels have high brightness requirements. If we focus on increasing the brightness of the display panel, the requirements for the light-emitting devices in the panel will increase, and the power consumption of the display panel will likely also increase significantly. This would place higher demands on the battery of the display device. Therefore, directly increasing the brightness of the light-emitting devices is not actually a good technical solution for improving the brightness of the display panel.

[0029] Based on this, in related technologies, the brightness of the display panel can also be improved by setting a lens layer opposite to the pixel layer on the side of the pixel layer away from the substrate. It is understood that the lens layer includes several lenses, each positioned opposite the pixel opening area of ​​the pixel layer. Therefore, when the display panel is powered on and emits light, because the lens is a hemispherical structure with a light-gathering effect, it can concentrate the light, significantly improving the display brightness without increasing the brightness of the display panel itself.

[0030] In practical applications, whether a lens can achieve the effect of focusing light is closely related to the shape of the lens itself. If the lens in the lens layer of the actual manufactured display panel is deformed, the preset light-focusing effect cannot be achieved. Therefore, it is very important to detect the actual shape parameters of the lens in the lens layer during the inspection of the display panel.

[0031] The prerequisite for using lenses to enhance display brightness in a display panel is that the shape of each lens in the lens layer matches the preset requirements. For example, the height and sidewall angle of the lens must also conform to the preset requirements. Therefore, to ensure accurate brightness enhancement, the shape of the lenses needs to be thoroughly inspected during factory testing. However, because microlenses are transparent, their height and sidewall angle parameters are difficult to obtain in practice, making this inspection process quite challenging.

[0032] Based on this, this application proposes a display panel and display device that can solve the problem that the detection process is difficult because the lens is a transparent structure and its height and sidewall angle parameters are not easy to obtain. This significantly improves the accuracy of lens positioning and the efficiency of detection.

[0033] Figure 1 This is a schematic diagram of a display panel according to an embodiment of this application. The display panel can be disposed in a display device. (Reference) Figure 1 The display panel includes a pixel layer and a lens layer disposed opposite to the pixel layer in the orthographic projection direction.

[0034] Understandably, the aforementioned display panels often require pixel layers comprising multiple primary colors of light emission to emit different colors of light, thereby displaying any number of different colors on the display panel. Furthermore, as mentioned earlier, to improve the display brightness of the display panel, a lens layer can be disposed on the side opposite to the frontal projection direction of the pixel layer. This lens layer includes multiple lenses corresponding to the pixel opening areas.

[0035] In this embodiment, the lens layer is disposed on the side of the pixel layer away from the substrate in the display panel, and is spaced apart from the pixel layer.

[0036] like Figure 1 As shown,Figure 1 The image shows a side cross-sectional view of the lens layer and pixel layer. Figure 1 It can be seen from this that Figure 1 It includes a pixel layer 11 and a lens layer 12 disposed opposite to the pixel layer 11 in the orthogonal projection direction. The lens layer 12 includes a plurality of lenses 121.

[0037] In this embodiment, in the non-display area of ​​the display panel, a plurality of positioning structures are provided on the first film layer and / or the second film layer of the lens layer on the side close to the display panel substrate. The first film layer is an adjacent film layer of the lens layer, and the second film layer is a spacer film layer of the lens layer.

[0038] As is understood from the foregoing, related technologies require the detection of morphological parameters of the lenses in the lens layer, such as lens height and lens sidewall angles. However, since the lenses are transparent, the measurement positions for lens height and sidewall angles are not easily selected. In this embodiment, to detect the relevant parameters of the lenses, the detection position needs to be located. That is, the positioning structure in this embodiment is used to locate the detection position of the lenses in the lens layer. Simultaneously, to ensure that positioning does not affect the normal display of the display panel, since all lenses in the lens layer are made using the same equipment, the positioning structure can be placed in a non-display area, i.e., the non-AA area of ​​the display panel. This allows for the location of the detection position of the lenses in the display panel without affecting the display function of the display panel.

[0039] In this embodiment, the positioning structure described above can be a structure used to indicate the center position of the lens in the lens layer. It is understood that the morphological parameters of the lens layer may include the lens height parameter, the lens sidewall angle parameter, etc., wherein both the lens height parameter and the sidewall angle parameter need to be determined based on the center position of the lens.

[0040] For example, the above positioning structure can be a positioning groove or a positioning recess, and the embodiments of this application do not limit it in this way.

[0041] In this embodiment, since the positioning structure is used to locate the center position of the lens and is located in a non-display area, the coating layer can be flexibly defined. That is, the positioning structure can be viewed from the orthographic projection direction, thus providing a positioning interface for the lens between multiple positioning structures.

[0042] In one example, a plurality of positioning structures are provided on the first film layer of the lens layer on the side closest to the display panel substrate. In this case, the positioning structures are provided on the film layer adjacent to the lens layer.

[0043] In one example, a plurality of positioning structures are provided on the second film layer of the lens layer on the side closest to the display panel substrate. In this case, the positioning structures are provided on the film layer spaced apart from the lens layer.

[0044] In one example, multiple positioning structures are provided on the first and second film layers of the lens layer on the side closest to the display panel substrate. In this case, the positioning structures can be respectively provided on the film layers adjacent to the lens layer and on the film layers spaced apart from the lens layer. Specifically, as can be seen from the foregoing, since the positioning structures can be viewed from the orthographic projection direction, the center position of the lens among the multiple positioning structures can be determined. Therefore, even if the positioning structures are provided on different film layers, it is possible to view the positioning structures and thus locate the center position of the lens.

[0045] In the embodiments of this application, in the non-display area of ​​the display panel, the above-mentioned multiple positioning structures can be set in a first film layer and / or a second film layer corresponding to the orthogonal projection direction between all adjacent lenses, or they can be set in a first film layer and / or a second film layer corresponding to the orthogonal projection direction between some adjacent lenses. The embodiments of this application do not limit this.

[0046] Understandably, in practical applications, the morphological parameters of all lenses in the non-display area can be detected, or the morphological parameters of some lenses in the non-display area can be detected.

[0047] Furthermore, during the detection of the morphological parameters of some lenses, the lens whose center is located between the arrangement directions of any two positioning structures can be one or more, and this application embodiment does not limit this.

[0048] In this embodiment of the application, the lens layer includes a plurality of lenses, and at least one lens is disposed in the arrangement direction of any two of the plurality of positioning structures, and the arrangement direction of any two of the positioning structures overlaps with the center of each of the at least one lens.

[0049] It is understood that in the embodiments of this application, there are multiple positioning structures. If any two positioning structures are connected in the direction of arrangement to form a positioning area, then the center of the lens between the two positioning structures is located in the positioning area.

[0050] In one example, when the above positioning structure is a positioning groove, any two positioning structures connected in the arrangement direction can form a long strip positioning area in the orthographic projection direction. In this long strip positioning area, the center of the lens between the two positioning structures is included.

[0051] In one example, when the above positioning structure is a positioning point, any two positioning structures connected in the arrangement direction can form a positioning connection line in the orthographic projection direction. The center of the lens between the two positioning structures is included on this positioning connection line.

[0052] The following is through Figures 1 to 4 The positioning structure and the membrane layer used to set the positioning structure are described.

[0053] Figure 2 This is a schematic diagram of the display panel, from which it can be seen that... Figure 2 The display includes a display area 21 and a non-display area 22 of the display panel. The area used to set the positioning structure in this application is a local area 221 in the non-display area 22.

[0054] Next, regarding the Figure 2 Enlarge it. Figure 3 That is Figure 2 A magnified view of the part in the orthographic projection direction, that is Figure 3 for Figure 2 Top view of area 221 in the middle. Figure 3 It can be seen that it includes pixels of three different colors: green pixel 311, red pixel 312, and blue pixel 313. A lens 121 is set at the pixel opening area of ​​each pixel. Figure 2 In the middle, viewed from the orthographic projection direction, a positioning structure 314 can be seen between the different lenses. This positioning structure 314 is composed of... Figure 1 As can be seen from the side view, the adjacent film layers located at lens 314 will be discussed later. Figure 1 Detailed description is provided.

[0055] Next, along Figure 3 The local image cropping line 315 formed by the arrangement direction of any two positioning structures 314 is used to crop the pixel opening area corresponding to the arrangement direction of the two positioning structures 314, as follows: Figure 4 As shown, in Figure 4 for Figure 3 A partial top view corresponding to the cropping line 315 in the partial image. This top view shows that the centers 41 of each of the three lenses 121 are located in the arrangement direction of the two positioning structures 314. Furthermore, in this… Figure 4 In the middle, the two positioning structures 314 are connected in the arrangement direction to form a positioning area 42, and the center 41 of each of the three lenses 121 is located in the positioning area 42.

[0056] Finally, Figure 4 The side view section taken along line 315 of the local image is... Figure 1 .like Figure 1 As shown, in Figure 1The image shows the first film layer 13, that is, the film layer adjacent to the lens, in... Figure 1 The image shows two positioning structures 314 positioned on the first CT slice 13. In addition, in... Figure 1 It also includes the following film layers: BP layer 14, PDL layer 15, anode layer 16, W-EL film layer 17, cathode layer 18, TFE layer 19, second CT layer 20, adhesive layer 21, and CG layer 22. Among them, the above... Figures 3 to 4 The hexagonal similar opening area is formed by the PDL layer 15. The lens 121 is disposed in the adhesive layer 21, thereby fixing it.

[0057] The display panel provided in this application includes a pixel layer and a lens layer disposed opposite to the pixel layer in the orthographic projection direction. In the non-display area of ​​the display panel, multiple positioning structures are disposed on a first film layer adjacent to the lens layer and / or a second film layer spaced apart from the lens layer on the side of the lens layer near the display panel substrate. The lens layer includes multiple lenses, and at least one lens is disposed in the arrangement direction of any two positioning structures, and the arrangement direction of any two positioning structures overlaps with the center of each of the at least one lens. Thus, by providing multiple positioning structures for positioning the center position of the lenses in the non-display area, the center position of the lens can be determined based on these positioning structures during the subsequent determination of the lens's morphological parameters. Based on this center position, key morphological parameters of the lens, such as height parameters and sidewall angle parameters, can be determined, thereby significantly improving the accuracy and efficiency of detecting lens morphological parameters.

[0058] In another embodiment of this application, a specific implementation method for improving the lens center position confirmation method by different arrangement methods of the positioning structure is also provided. For example, when the dimension of the orthographic projection pattern of the positioning structure in the vertical direction along the arrangement direction of the positioning structure is greater than a preset threshold, the adjacent positioning structures are staggered in the vertical direction of the arrangement direction.

[0059] It is understood that in this embodiment, the various morphological parameters of the lens are determined by locating the center of the lens using a positioning structure. However, the positioning structure is also generated on the first or second film layer using methods such as mask etching or laser etching. If the positioning structure is too large in the vertical direction of the arrangement direction after being generated using different methods, the user may need to determine the center of the lens within a large area, making it difficult to quickly locate the center. Therefore, by misaligning the positioning structure, the center of the lens can be locked within a smaller area in the vertical direction of the arrangement direction, thus facilitating the user in determining the center of the lens.

[0060] likeFigure 4 As shown, Figure 4 The direction shown by A-A' is the arrangement direction of the positioning structure 314, and the direction perpendicular to the arrangement direction is the direction shown by B-B'. Figure 4 If the dimension d1 of B-B' perpendicular to the arrangement direction of the positioning structure 314 is greater than a preset threshold, then misalignment is required. For example... Figure 5 As shown, in Figure 5 As can be seen from the diagram, the two positioning structures 304 are misaligned in the vertical direction B-B', so the dimension d2 of the vertical direction B-B' along the arrangement direction of the positioning structures 314 is less than the preset threshold.

[0061] For example, the aforementioned preset threshold can be a custom setting or a user setting, and this application embodiment does not limit this.

[0062] It is understood that the above-mentioned preset threshold can be determined based on the speed at which the lens center is to be determined by the user and the center diameter of the lens center, and this application embodiment does not limit this.

[0063] Optionally, in this embodiment of the application, the adjacent positioning structures include a first structure and a second structure, wherein the first positioning structure has a first part and the second positioning structure has a second part.

[0064] For example, the maximum distance between the first part and the second part in the vertical direction of the arrangement direction is less than the first dimension.

[0065] For example, the first dimension is the sum of the dimension of the first part in the vertical direction of the arrangement direction and the dimension of the second part in the vertical direction of the arrangement direction.

[0066] like Figure 6 As shown, Figure 6 for Figure 5 An enlarged schematic diagram of the positioning structure, from Figure 6 As can be seen, the two positioning structures 314 mentioned above each include a first part 3141 of the first positioning structure 314 and a second part 3142 of the second positioning structure 314. In the direction perpendicular to the arrangement direction, that is, in the B-B' direction, the maximum distance between the first part 3141 and the second part 3142 is d2. The first dimension is the sum of the dimensions of the first positioning structure 314 and the second positioning structure 314 in the direction perpendicular to the arrangement direction, that is, in the B-B' direction, d3. It can be seen that d2 is significantly smaller than d3. That is, by setting the offset, the area used for the lens center can be reduced, making it convenient for users to quickly locate the lens center and thus determine the shape parameters of the lens.

[0067] In another embodiment of this application, it is also provided that the positioning structures can be disposed at specific locations on different film layers. For example, each of the above-mentioned positioning structures is disposed on a first film layer and / or a second film layer corresponding to the region between two adjacent lenses.

[0068] It is understood that, in the embodiments of this application, the above-mentioned positioning structure can be disposed on the first film layer, or the second film layer, or the first film layer and the second film layer in the orthogonal projection direction. However, regardless of which film layer or layers it is disposed on, the position of the positioning structure in the orthogonal projection direction is in the area between different lenses.

[0069] like Figure 1 As shown in the diagram, the positioning structure 314 is disposed on the first film layer, that is, the first CT layer 13, and each positioning structure 314 is located between different lenses 121 in the orthographic projection direction.

[0070] like Figure 7 As shown, in Figure 7 In this process, the positioning structure is set in the TFE film layer 19. The TFE film layer 19 is not directly adjacent to the lens 121. Therefore, the TFE film layer 19 belongs to the second film layer. The TFE film layer 19 includes two positioning structures 191. Each positioning structure 191 is located between different lenses 121 in the orthographic projection direction.

[0071] like Figure 8 As shown, in Figure 8 In this process, the positioning structure is set in the second CT layer 20. The second CT layer 20 is not directly adjacent to the lens 121. Therefore, the second CT layer 20 belongs to the second film layer. The second CT layer 20 includes two positioning structures 201. Each positioning structure 201 is located between different lenses 121 in the orthographic projection direction.

[0072] In another embodiment of this application, specific implementations are provided that allow the positioning structure to have different shapes. For example, the projection shape of the positioning structure in the orthographic projection direction includes: an arc or a polygon.

[0073] It is understood that, in the embodiments of this application, the projection shape of the above-mentioned positioning structure in the orthographic projection direction is not specifically limited.

[0074] In one example, if the projection shape of the aforementioned positioning structure in the orthographic projection direction is an arc, then the projection shape may include: an ellipse or a circle. For example, as described above. Figures 4 to 6 As can be seen, the projected shape of the positioning structure is circular.

[0075] In one example, if the projection shape of the aforementioned positioning structure in the orthographic projection direction is an arc, then the projection shape can include: a regular polygon, a rectangle, or a polygon. For example, as described above. Figure 9 It can be seen from this that Figure 9 The positioning structure is shown as Figure 8 The projection shape of the positioning structure 201 in the orthographic projection direction is a square.

[0076] In another embodiment of this application, a specific implementation method for the size parameters of the positioning groove is provided when the positioning structure can be a positioning groove. For example, the positioning structure is a positioning groove, the groove depth is less than the film thickness of the film layer in which the positioning groove is located, and the diameter of the positioning groove is less than the spacing distance between lenses adjacent to the positioning structure.

[0077] It is understood that in the embodiments of this application, the aforementioned positioning groove can be either a positioning recess or a positioning protrusion, and the embodiments of this application do not limit this. For example, when the aforementioned positioning groove can be a positioning recess, as described above... Figure 1 As shown, in Figure 1 In the middle, two positioning grooves 314 are disposed in the first CT film layer 13; when the above positioning grooves can be used as positioning protrusions, in Figure 8 In the middle, two positioning grooves 201 are set in the second CT film layer 20.

[0078] Furthermore, the convex and concave directions of the aforementioned positioning grooves and positioning protrusions are opposite. For example, when viewing the positioning structure from a projection direction away from the substrate to a projection direction closer to the substrate, the groove's convex and concave direction, which is the same as this projection direction, belongs to the groove, and the groove's convex and concave direction, which is the same as this projection direction, belongs to the protrusion. Therefore, the aforementioned... Figure 1 The positioning structure 314 in the middle belongs to the positioning groove 314, and in contrast, the above... Figure 8 The positioning structure 201 in the middle belongs to the positioning protrusion 201.

[0079] For example, the aforementioned positioning groove is located in a non-display area. However, for a display panel, the non-display area often has other functions besides display. Therefore, it is necessary to ensure that the positioning groove is set without affecting the function of the display panel. Based on this, the depth of the aforementioned positioning groove should be less than the film thickness of the film layer in which the positioning groove is located.

[0080] In one example, the depth of the positioning groove can be 0.05–1 μm. For instance, the depth of the positioning groove can be 0.2 μm.

[0081] In one example, the diameter of the positioning groove can be 0.1–2 μm. For example, the diameter of the positioning groove can be 0.5 μm.

[0082] In another embodiment of this application, a specific manifestation of the second film layer is provided when the positioning structure can be disposed in the second film layer. For example, the second film layer is the unencapsulated organic layer and the unencapsulated metal layer in the aforementioned display panel.

[0083] It is understandable that, when the positioning structure is set in the second membrane layer, the second membrane layer with certain setting conditions can be equipped with the positioning structure.

[0084] In one example, the aforementioned EL layer cannot be used to set up a positioning structure because the EL layer is a film layer used to control the light emission of the display panel, and it needs to be fully encapsulated. Therefore, it cannot be used to set up a positioning structure.

[0085] In one instance, the cathode layer cannot be used to set up a positioning structure because the cathode layer is a metal layer that needs to be fully encapsulated, and therefore cannot be used to set up a positioning structure.

[0086] In another embodiment of this application, a specific manner in which the second film layer can be disposed of is also provided, whereby the positioning structures can be disposed in the second film layer. For example, when the aforementioned multiple positioning structures are disposed in the second film layer, the second film layer is a non-patterned film layer coated entirely on top of each other.

[0087] As can be understood from the foregoing, since the location and size of the positioning structure have certain requirements, the film layer used to set the positioning structure should be a full-layer coating without any breaks.

[0088] Furthermore, in the embodiments of this application, since the positioning structure is set in the non-display area, the film layer that only has functions and is not fully coated in the display area can be set as a fully coated film layer in the non-display area.

[0089] The following two examples illustrate how the non-full-surface coated film can be configured as a full-surface coated film.

[0090] First example: A pixel layer that is coated across the entire surface.

[0091] In another embodiment of this application, a specific representation of the pixel layer is provided when the positioning structures can be disposed in the pixel layer. For example, when the second film layer includes a pixel layer and the plurality of positioning structures are disposed in the second film layer, the pixel layer is a monochrome pixel layer.

[0092] like Figure 10As can be seen, since the positioning structure is set in the non-display area, the above pixel layer can be a monochrome pixel layer. If the entire layer is coated, then the monochrome pixel layer 11 can include multiple positioning structures 111.

[0093] It is understood that the aforementioned monochrome pixel layer can be any color among the three-color pixels, and this application embodiment does not limit this.

[0094] The second example: an anode layer with no patterning on the front.

[0095] In another embodiment of this application, a specific manner in which the anode layer can be disposed when the positioning structure is disposed on the anode layer is also provided. For example, when the second film layer includes the anode layer and the plurality of positioning structures are disposed on the second film layer, the anode layer in the non-display area is a full-layer coated film layer, and the adjacent film layer on the side of the anode layer away from the substrate is a full-layer encapsulation layer.

[0096] like Figure 11 As can be seen, since the positioning structure is set in the non-display area, the anode layer 16 does not need to be patterned with a PDL layer. That is, compared with the display area, the PDL layer is no longer set in the non-display area. The anode layer 16 is set on the BL substrate 14 in its entirety. Then, the anode layer 16 can include multiple positioning structures 161.

[0097] As described above, in the embodiments of this application, during the detection of the morphological parameters of some lenses, the lens whose center is located between any two positioning structures can be one or more. That is, the arrangement of the positioning structures is relatively free, as long as it can position the lens placed between the two positioning structures.

[0098] In one example, as described above Figure 1 As shown, the lens whose center is located between the arrangement directions of any two positioning structures can be a single lens, that is, there is a lens 121 between the two positioning structures 134.

[0099] In one example, such as Figure 12 As shown, by Figure 12 Yes, the local image cropping line 316 is formed by the arrangement direction of the two positioning structures 112, and the two positioning structures 112 are equipped with two lenses 121.

[0100] In one example, such as Figure 13 As shown, by Figure 13 Yes, the local image capture line 317 is formed by the arrangement direction of the three positioning structures 113. Two lenses 121 are set between two of the three positioning structures 113, and one lens 121 is set between the other two positioning structures 113.
