Detailed Description
In addition to compressing the entire screen of the "bang" design represented by iPhone X, which is not displayed in the upper and lower non-display areas of the mobile phone, the entire screen in which photosensitive elements such as a camera are disposed in the display area is also under study.
To setting up the comprehensive screen in display area with photosensitive assembly such as camera, as shown in fig. 1, for photosensitive assembly such as camera in display area corresponds position department, digs the structural sketch of display panel of hole design to partial rete, through having dug a via hole P on partial rete of display panel, photosensitive assembly 30 such as camera corresponds with via hole P to make light can see through photosensitive assembly 30 such as camera through via hole P. After the via hole P is dug on the film layer, a large-area pit may exist at the position of the via hole P, and when the last film layer located on the film layer is coated, due to the fluidity of the film layer material, the film layer material located around the via hole P may flow into the via hole P, so as shown in fig. 1, the height of the isolation column 40 near the via hole P may not be enough to support between the upper and lower substrates, so that after Seal stitching, the box thickness near the via hole P may be smaller than the normal display area (i.e. the area far away from the via hole P), and because the box thicknesses are different, the light with different wavelengths may penetrate through more easily, and the blue light may penetrate more easily when the liquid box thickness is lower, thereby causing the problem that the blue light is likely to appear near the via hole P of the display panel.
The embodiment of the invention provides a display panel and a display device, aiming at the problem that light sensing components such as a camera are arranged in an AA area and are blued near a through hole P of the display panel in a full screen.
The following describes in detail a specific embodiment of a display panel and a display device according to an embodiment of the present invention with reference to the drawings. The thicknesses and shapes of the various film layers in the drawings are not to be considered true proportions, but are merely intended to illustrate the present invention.
As shown in fig. 2, a display panel provided in an embodiment of the present invention is a cross-sectional schematic view of the display panel provided in the embodiment of the present invention, and includes: a first substrate 10 and a second substrate 20 disposed opposite to each other, and a plurality of spacers 40 supported between the first substrate 10 and the second substrate 20, the plurality of spacers 40 being located at least in a display region (i.e., a region shown by a) and a first non-display region (i.e., a region shown by B);
the first substrate 10 includes a first substrate 101 and a first insulating layer 102, the first insulating layer 102 is provided with first via holes M in a light-transmitting hole region (i.e., a region indicated by C), at least one isolation pillar 40, whose distance from the first via holes M is within a preset range, has a corresponding support 103, and an orthographic projection of the support 103 on the first substrate 101 at least partially overlaps with an orthographic projection of the at least one isolation pillar 40 on the first substrate 101. Wherein, one support 103 corresponds to one isolation pillar 40, and then at least a portion of the orthographic projection of each support 103 on the first substrate 101 overlaps with the orthographic projection of the corresponding isolation pillar 40 on the first substrate 101, of course, one support 103 may also be used to support a plurality of isolation pillars 40, or for the sake of supporting reliability, one isolation pillar 40 may also be supported by a plurality of supports 103, which is not limited in the embodiment of the present invention.
According to the display panel provided by the embodiment of the invention, the corresponding support body 103 is arranged on the isolation column 40 around the first through hole M, the support body 103 is used for compensating the height of the collapsed film layer, and the collapse degree around the hole after Seal pressing is reduced through the matching of the isolation column 40 and the support body 103, so that the box thickness around the hole is consistent with that of the display area, the passing difficulty of blue light is increased, and the problem of blue light around the hole is further reduced.
In the display panel provided by the embodiment of the present invention, the first via hole M may be selected as a light-transmitting hole of a camera, and is generally a front-facing camera. In a specific implementation, the first via hole M may also be a light-transmitting hole of another component, such as another photosensitive component, and the embodiment of the invention is not limited thereto.
In the display panel provided in the embodiment of the present invention, the isolation pillar 40 may be formed on the first substrate 10, or the isolation pillar 40 may be formed on the second substrate 20, or the isolation pillar 40 may include two parts, one part is formed on the first substrate 10, and the other part is formed on the second substrate 20, which is not limited in the embodiment of the present invention.
Fig. 3 and fig. 4 are a top view and an enlarged schematic view of a partial region of the display panel in an embodiment of the present invention, respectively, and a cross-sectional view in an embodiment of the present invention is a cross-sectional view cut along any straight line passing through the first via M in fig. 3 or fig. 4, for example, fig. 2 is a cross-sectional view cut along a straight line passing through the first via M in fig. 3. It should be noted that, in order to clearly illustrate the structure of the light-transmitting hole region C and the first non-display region B surrounding the light-transmitting hole region C, the light-transmitting hole region C shown in the figure is relatively large, and in a specific implementation, the size and the position of the light-transmitting hole region C may be set according to the requirement of an actual component to be mounted, and herein, the illustration is only for convenience of illustration, and the size and the position of the light-transmitting hole region C are not limited, and the illustration is made in fig. 2 and 3 by taking the light-transmitting hole region C as a circle, in a specific implementation, the light-transmitting hole region C may also be in other shapes, such as an oval, a polygon, and the position of the light-transmitting hole region C may also be any position in the display panel, and herein, not limited. In addition, although one light-transmitting hole region C is illustrated in fig. 2 and 3 as an example, in the specific implementation, the number of the light-transmitting hole regions C may be set according to the requirement of actually mounting components, for example, if a front camera and other photosensitive components are required to be mounted in a mobile phone, two or more light-transmitting hole regions C need to be provided on the display panel.
As shown in fig. 3 and 4, the display panel includes a display area a, a first non-display area B, a light hole area C, and a second non-display area D, where the second non-display area D surrounds the display area a, the second non-display area D is generally a frame area around the display area a, the display area a surrounds the first non-display area B, and the first non-display area B surrounds the light hole area C, and it can be seen that the area occupied by the first non-display area B is smaller.
In the embodiment of the present invention, since the size and the depth of the first via hole M are limited during the specific implementation, the material of the film layer flowing into the first via hole M is limited, and therefore, only a small range of the isolation pillar 40 around the first via hole M needs to be supported, generally, the upper limit of the preset range is less than or equal to the distance between the light-transmitting hole region C and the display region a, that is, only the isolation pillar 40 located in the first non-display region B can be supported, and then the support body 103 is correspondingly disposed only in the first non-display region B.
Specifically, under the condition that the first non-display area B has a sufficient space, one or more than one isolation pillars 40 may be provided, and since the support body 103 may be provided below each isolation pillar 40, and the support effect may be further improved by providing more support bodies 103, the box thickness around the first via hole M and the box thickness of the normal display area a may be kept consistent even more, and further, the blue-tinged effect occurring around the first via hole M may be reduced better.
As shown in fig. 5, in the case where only one spacer 40 is provided, the number of the support bodies 103 may be one, and as shown in fig. 6, in the case where two spacer 40 are provided, the number of the support bodies 103 may be two, and when a plurality of support bodies 103 are provided, the plurality of support bodies 103 may be arranged concentrically, similarly to the structure of fig. 6.
In the embodiment of the present invention, in the isolation pillars 40 provided with the corresponding support body 103, an orthogonal projection of each isolation pillar 40 on the first substrate 101 and an orthogonal projection of the corresponding support body 103 on the first substrate 101 may be overlapped, as shown in fig. 7 in particular. Alternatively, in order to improve the reliability of the support, the orthographic projection of the isolation pillar 40 on the first substrate 101 may be located in the orthographic projection of the corresponding support 103 on the first substrate 101, which is specifically illustrated in fig. 5 and 6.
Specifically, the orthographic projection of the isolation pillar 40 on the first substrate 101 refers to the orthographic projection of a plane of the isolation pillar 40 close to the first substrate 101 on the first substrate 101, and the orthographic projection of the support 103 on the first substrate 101 refers to the orthographic projection of a plane of the support 103 away from the first substrate 101 on the first substrate 101.
The display panel provided in the embodiment of the present invention may be selected as a liquid crystal display panel, that is, the first substrate 10 in fig. 2 may be selected as an array substrate, the second substrate 20 may be selected as a color film substrate, and a space between each of the spacers 40 and the first substrate 10 and the second substrate 20 is filled with a liquid crystal material. In addition, the display panel may also be other types of display panels, for example, the display panel may be an Organic Light-Emitting Diode (OLED) display panel, and correspondingly, the first substrate 10 may be an array substrate, and the second substrate 20 may be a package cover plate.
In an embodiment of the invention, fig. 8 is a schematic cross-sectional view of the first substrate 10. As shown in fig. 8, the first substrate 10 may further include a buffer layer 104, a second insulating layer 105, and a planarization layer 106. The buffer layer 104 is located between the first substrate 101 and the first insulating layer 102, the second insulating layer 105 is located on a side of the first insulating layer 102 away from the buffer layer 104, and the planarization layer 106 is located on a side of the second insulating layer 105 away from the first insulating layer 102.
Here, the first insulating layer 102 and the second insulating layer 105 are hollowed at positions corresponding to the light transmission hole regions C to form the first via holes M, so that the first insulating layer 102 and the second insulating layer 105 are only present in the display region a and the first non-display region B, while no holes are hollowed in the first substrate 101, the buffer layer 104, and the planarization layer 106, so that the first substrate 101, the buffer layer 104, and the planarization layer 106 are present in the display region a, the first non-display region B, and the light transmission hole regions C.
In the embodiment of the present invention, as shown in fig. 9, a schematic structural diagram of the second substrate 20 is specifically shown by taking the second substrate 20 as a color filter substrate. The second substrate 20 includes: the Black Matrix 202 is positioned on one side of the second substrate base plate 201 close to the first substrate 10, the color filter film layers 203 are positioned between the intervals of the Black Matrix 202, and the third insulating layer 204 is positioned on one sides of the color filter film layers 203 and the Black Matrix 204 close to the first substrate 10; the color filter film layer 203 is only present in the display area a, the black matrix 202 is only present in the display area a and the first non-display area B, and the third insulating layer 204 is present in the display area a, the first non-display area B, and the light-transmitting hole area C.
Specifically, the third insulating layer 204 is an optically transparent (OC) layer.
Specifically, the black matrix 202 and the color filter film layer 203 are not disposed in the transparent hole region of the second substrate 20, and a second via hole N is formed on the layer where the black matrix 202 and the color filter film layer 203 are located, and the second via hole N and the first via hole M are concentric holes.
In a specific implementation manner, in the display panel provided in an embodiment of the present invention, the support 103 at least includes the following implementation manners:
the implementation mode is as follows:
as shown in fig. 10, which is a second schematic cross-sectional view of the first substrate 10, the support 103 is disposed between the buffer layer 104 and the second insulating layer 105. In this way, the supporting function of the support body 103 can be transmitted to the isolation pillar 40 through the second insulating layer 105 and the planarization layer 106, so as to support the isolation pillar 40 to a certain extent, thereby reducing the collapse degree of the region near the first via hole M, and further reducing the blue phenomenon near the first via hole M. As shown in fig. 10, after the support 103 supports the second insulating layer 105, a protrusion may be formed on the second insulating layer 105, and the protrusion may support the planarization layer 106 and form a protrusion on the planarization layer 106, thereby supporting the isolation pillar 40. Here, in order to illustrate the supporting function of the supporting body 103, the thickness and size of the formed protrusion are enlarged in the schematic view shown in fig. 10, but do not represent the actual size.
In the embodiment of the present invention, the first metal layer M1 is disposed between the buffer layer 104 and the second insulating layer 105, and the support body 103 and the first metal layer M1 are made of the same material at the same layer, so that in the specific manufacturing process, the support body 103 and the first metal layer M1 can be manufactured in the same process, thereby avoiding the increase of the process for manufacturing the support body 103, saving one manufacturing process, and reducing the process cost. In practical applications, a gate layer is generally disposed between the buffer layer 104 and the second insulating layer 105, so that the support 103 and the gate layer can be disposed in the same layer and material.

The implementation mode is three:
as shown in fig. 13, which is a fifth schematic cross-sectional view of the first substrate 10, the support body 103 is disposed between the isolation pillar 40 and the planarization layer 106, so that the isolation pillar 40 around the isolation pillar first via M can be supported between the first substrate 10 and the second substrate 20 by the direct support of the support body 103, thereby reducing the collapse degree of the region near the first via M and further reducing the blue phenomenon near the first via M.
Specifically, the third metal layer M3 is disposed between the isolation pillar 40 and the planarization layer 106, and the support body 103 and the third metal layer M3 are made of the same material in the same layer, so that in the specific manufacturing process, the support body 103 and the third metal layer M3 can be manufactured by the same process, thereby avoiding the increase of the process for manufacturing the support body 103, saving the manufacturing process in one step, and reducing the process cost. In practical applications, for a display panel with a touch function, a touch routing layer is generally disposed on a flat layer, and the touch routing layer is generally made of a metal material, so that the supporting body 103 and the touch routing layer can be disposed on the same layer and made of the same material.
