Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated.
With the continuous development of display panel manufacturing technology, people have made higher demands on the performance and display effect of display panels and display devices.
As shown in fig. 1, fig. 1 is a schematic arrangement diagram of components in a display panel provided in the prior art. A color film substrate 101, an array substrate 102 and a supporting pillar 103 are disposed in the display panel 100. The color film substrate 101 and the array substrate 102 are disposed opposite to each other, and the supporting pillar 103 is disposed between the array substrate 102 and the color film substrate 101 to support the two opposite substrates.
Meanwhile, a metal layer 105 is further disposed on the array substrate 102. In the prior art, the support posts 103 are disposed directly on the metal layer 105. The metal layer 105 forms a bump structure on the array substrate. When the display panel 100 is under an external force, for example, under an external pressure, the supporting pillar 103 is displaced due to the raised metal layer 105, and thus the film layer contacting the supporting pillar in the region is damaged, which causes display and quality problems such as light leakage of the display panel.
The embodiment of the application provides a display panel and a display device, so that the displacement of a supporting column inside the display panel is effectively improved easily under the action of external force, and further the damage of an inner film layer of the display panel is caused, and the display and quality of the display panel are affected.
As shown in fig. 2, fig. 2 is a schematic view of a film structure of a display panel according to an embodiment of the present disclosure. In the embodiment of the present application, a partial structure of a display panel is taken as an example, and the partial structure is mainly an area where a supporting pillar is disposed.
Specifically, the display panel provided in the embodiment of the present application includes an array substrate 102, a color filter substrate 101, and a supporting pillar 103. The array substrate 102 and the color filter substrate 101 are disposed opposite to each other, and other functional film layers such as a liquid crystal layer may be disposed in an intermediate region between the array substrate 102 and the color filter substrate 101, which is not specifically shown in the example drawings.
Meanwhile, the supporting pillars 103 are disposed in an area where the array substrate 102 and the color filter substrate 101 are opposite to each other. The upper and lower end faces of the supporting pillars 103 are respectively and correspondingly disposed on two opposite faces of the array substrate 102 and the color filter substrate 101. When the color film substrate 101 or the array substrate 102 of the display panel is subjected to external compressive stress, the supporting column 103 arranged between the two substrates can effectively play a supporting role, so that the thickness and the performance of the display panel are maintained.
Further, a metal layer 105 is disposed on the array substrate 102, and the metal layer 105 is disposed on the array substrate 102 in a patternable manner. In the embodiment of the present application, the array substrate 102 is exemplified by a thin film transistor array substrate, and the metal layer 105 includes a first metal layer 201 and a second metal layer 202.
Preferably, the first metal layer 201 and the second metal layer 202 may be different functional layers of the array substrate, for example, the first metal layer 201 is an active layer of a thin film transistor in the array substrate, and the second metal layer 202 is a gate of the thin film transistor in the array substrate. Alternatively, the first metal layer 201 and the second metal layer 202 are other functional metal layers, and are not described in detail here.
In the embodiment of the present application, the display panel further includes a first insulating layer 211. Specifically, when the first metal layer 201 and the second metal layer 202 are disposed, the first metal layer 201 is disposed on the array substrate 102, the first insulating layer 211 is disposed on the first metal layer 201 and completely covers the first metal layer 201, and meanwhile, the second metal layer 202 is disposed on the first insulating layer 211. In the embodiment of the present application, the first metal layer 201 and the second metal layer 202 are disposed correspondingly, for example, the first metal layer 201 is disposed on a corresponding film layer above the second metal layer 202.
Further, the display panel further includes a second insulating layer 206, a first functional layer 207, a pixel electrode layer 208, a second electrode layer 204, and a black matrix layer 205. Specifically, the second insulating layer 206 is disposed on the second metal layer 202 and completely covers the second metal layer 202. Meanwhile, a first functional layer 207 is provided on the second insulating layer 206, a pixel electrode layer 208 is provided on the first functional layer 207, and the second electrode layer 204 is provided on one side of the black matrix layer 205. And finally the film layer structure shown in fig. 2 is formed.
In the embodiment, when the above film structures are disposed on the array substrate 102, a groove 26 is further disposed between adjacent first metal layers 201 and between adjacent second metal layers 202.
Specifically, in the region corresponding to the groove 26, no metal layer is provided. Meanwhile, one end of the supporting column 103 is correspondingly arranged in the groove 26.
Since the metal layers 105 are stacked on each other when the metal layers are disposed, the metal layers are finally formed into protrusions having a certain height in the corresponding regions. In the embodiment of the present invention, when the above-mentioned layers are prepared, a step structure is formed on the array substrate 102 by each layer, that is, the step corresponds to the groove 26 provided in the embodiment of the present invention. In the area corresponding to the groove 26, no metal layer may be disposed, i.e., the projection of the metal layer on the array substrate does not coincide with the projection of the support pillar 103 on the array substrate 102.
Further, in the embodiment of the present application, in the region of the groove 26, the height of the surface film layer in the groove 26 is smaller than the corresponding height of the film layer at the metal region. Specifically, the distance from the pixel electrode 208 to the bottom surface of the array substrate in the area of the groove 26 is smaller than the distance from the pixel electrode 208 to the bottom surface of the array substrate in the area of the non-groove 26. Thereby forming a height difference between the films in different areas on the array substrate.
Specifically, as shown in fig. 3, fig. 3 is a schematic view of a partial film structure in the display panel according to the embodiment of the present disclosure. The structure of the display panel in fig. 2 is schematically shown. In the embodiment of the present invention, the array substrate may be configured as a stacked structure with multiple layers in different regions, but the outer contours of the layers formed after stacking are configured according to the structure in the embodiment of the present invention. Therefore, when the inner film layer structure of the display panel is described, the description will be given by using the simplified schematic diagram of the film layer in fig. 3 as it is.
In the embodiment, a first region 303, a second region 304, and a third region 305 are respectively corresponding to the array substrate 102. The first region 303, the second region 304, and the third region 305 are sequentially disposed above the array substrate. The metal layer 105 is disposed in the first region 303 and the second region 304, and the groove 26 is disposed in the third region 305.
In the embodiment of the present application, when the film layers are disposed, each film layer has a first platform 301 and a second platform 302 in the third area 305 corresponding to the groove 26. Specifically, the height from the first platform 301 to the bottom surface of the array substrate 102 is less than the height from the second platform 302 to the bottom surface of the array substrate 102.
That is, the first land 301 is the bottom surface of the groove 26. Meanwhile, the height from the first platform 301 to the upper surface of the array substrate may be greater than the height from the first metal layer 201 to the upper surface of the array substrate. At this time. The height of the first mesa 301 is greater than the height of the first metal layer 201.
In the embodiment of the present application, the first platform 301 and the second platform 302 are both disposed to be flat, and at the same time, the cross-sectional width of the first platform 301 may be made larger than that of the second platform 302.
Preferably, in the embodiment of the present application, the difference between the first platform 301 and the second platform 302 may be 0.5um to 1.5 um. Specifically, when the first metal layer 201 and the second metal layer 202 are provided to have the same thickness, the first metal layer 201 and the second metal layer 202 are both provided to be thicker
At this time, the fault difference may be made 1.5 um. When the first metal layer 201 and the second metal layer 202 are configured as a thinner layer, for example, the first metal layer 201 and the second metal layer 202 are both configured as
At this time, the fault difference was 0.5 um. Furthermore, the numerical value of the fault difference can be set according to the thickness of the actual product.
Meanwhile, the pixel electrode layer 208 may be continuously disposed in each region. At this time, the pixel electrode layer 208 is a continuous transition film layer between the first platform 301 and the second platform 302. In the present embodiment, the film in the region where the first platform 301 and the second platform 302 are connected has a slope.
Preferably, the slope may be set between 30 ° and 80 ° to ensure that the end of the support post 103 is well within the recess.
Meanwhile, in order to prevent interference of components between different regions, in the embodiment of the present application, a projection of the first platform 301 on the array substrate may not coincide with a projection of the first metal layer and a projection of the second metal layer on the array substrate.
Further, in the embodiment of the present application, two ends of the supporting column 103 may be a first end 1031 and a second end 1032, respectively. The first end 1031 is disposed on one side of the color filter substrate, and the second end is disposed in the groove on one side of the array substrate. Preferably, the second end 1032 can be made to correspond to a cross-sectional area that is smaller than the area of the first platform 301 within the recess, thereby allowing the support post 103 to be fully seated within the recess. When the supporting part slides relatively, the side edges at two sides of the groove can block the supporting column 103 from moving, so that the quality and reliability of the display panel are ensured.
Meanwhile, in the embodiment of the present application, when the second end 1032 is provided, the second end 1032 may not contact with the bottom side of the groove. Further, in the embodiment of the present application, in the region corresponding to the groove, the film layer at the bottom of the groove may be continuous or discontinuous with the film layers on both sides.
In the embodiment of the present application, when the supporting pillar 103 is disposed, the cross-sectional area of the first end 1031 may be larger than that of the second end 1032. The larger the area of the end face of the supporting column is, the smaller the stress formed between the supporting column and the corresponding substrate is, so that the stability of the display panel can be guaranteed better when the display panel is under the action of a large external force, and the comprehensive performance of the display panel is improved.
In the above embodiment, two step platforms formed by the first platform and the second platform are taken as an example for explanation, and preferably, a plurality of step platforms may be further provided in the third region 305 corresponding to the groove 26. When a plurality of step platforms are provided, the action principle is the same as that described above, and detailed description is omitted here.
Specifically, as shown in fig. 4, fig. 4 is a schematic view of another supporting column structure provided in the embodiment of the present application. In the present embodiment, the support column 103 may include a central support 1033 and a peripheral support 1034.
The central support portion 1033 is disposed at the second end of the supporting pillar 103, the peripheral support portion 1034 and the central support portion 1033 are disposed in a concentric circle, and the central support portion 1033 is disposed at one side of the peripheral support portion 1034, which are connected to form the supporting pillar 103 provided in the embodiment of the present application.
In the embodiment of the present application, the radius of the central supporting portion 1033 is smaller than the radius of the peripheral supporting portion 1034. Specifically, in the edge region 410 of the second platform 302, the peripheral support 1034 contacts the second platform 302, i.e. the edge of the peripheral support 1034 can be engaged with the second platform 302.
Meanwhile, the end surface of the center support 1033 in the embodiment of the present application is in contact with the bottom surface of the groove 26. When the supporting column is acted by external pressure, an acting force is formed on the supporting column in the edge area 410 of the second platform 302 and at the bottom of the groove 26, so that the force acting on each film layer of the display panel is effectively dispersed, and the problem of stress concentration is effectively reduced. Thereby effectively ensuring the quality and reliability of the display panel and the display device.
Further, in the embodiment of the present application, when the central supporting portion 1033 is disposed, the central supporting portion 1033 may be in a clearance fit or an interference fit with the bottom surface of the groove 26. When the display panel is compressed by force, the length of the supporting column is shortened, so that the central supporting portion 1033 is in contact with the bottom surface of the groove 26 under the action of force, and a constant thickness is maintained between the two opposite substrates.
Meanwhile, the peripheral support portion 1034 and the second platform 302 may be in clearance fit, and when the supporting pillar is pressed, the peripheral support portion 1034 may contact the second platform 302, thereby ensuring the supporting effect of the supporting pillar. Meanwhile, when the support pillar is not under stress, the peripheral support portion contacts the second platform 302, but there is no stress between the peripheral support portion 1034 and the second platform 302. Thereby the normal work of this display panel rete is effectual guaranteed.
Further, the supporting column can be provided with a plurality of peripheral supporting parts, and the plurality of supporting parts can be correspondingly contacted with the edge of each platform. When the display panel is stressed, the supporting column has a good supporting effect, and meanwhile, when the supporting column is under the action of external force, the supporting column cannot move due to limitation of side acting force and limitation of acting force of the bottom groove. Therefore, the integrity of the inner film layer in the area is effectively ensured, and the luminous effect and the comprehensive performance of the display panel are effectively improved.
Further, as shown in fig. 5, fig. 5 is a schematic plan view of a film structure provided in the present application. In the display panel 500, the support posts 103 and the first and second metal layers 201 and 202 are disposed. The first metal layer 201 and the second metal layer 202 are patterned on the array substrate corresponding to the display panel.
In the embodiment of the present application, one end of the supporting column 103 is disposed in the corresponding region of the groove 26. In the embodiment of the present application, the supporting pillars 103 are not overlapped with the metal layer and are correspondingly disposed in the grooves 26. When the supporting column is acted by external force, the supporting column 103 can not move in the groove 26 and can not damage the film layer, so that the film layer at each region can be effectively protected, the quality of the display panel can be ensured, and the luminous effect can be ensured during normal operation.
Further, in an embodiment of the present invention, a display device is further provided, where the display device includes a display panel. The supporting columns and the corresponding film layers in the display panel are arranged according to the film layer structure in the embodiment. When the display device is under the action of external force, the supporting column can effectively support the device and does not slide in the stress process.
Specifically, the display panel and the display device prepared by the method can be applied to any products or components with display functions, such as mobile phones, computers, notebook computers, digital photo frames, and the like, and the specific type of the products or components is not particularly limited.
In summary, the display panel and the display device provided by the embodiments of the present invention are described in detail above, and the principle and the implementation manner of the present invention are described herein by applying specific examples, and the description of the above embodiments is only used to help understanding the technical solution and the core idea of the present invention; although the present invention has been described with reference to the preferred embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, and that various changes and modifications may be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
