Description

Display panel and display device

Technical Field

The present invention relates to the field of display technologies, and in particular, to a display panel and a display device.

Background

The liquid crystal display panel (Liquid Crystal Display, LCD) is widely used because of its thin body, power saving, no radiation, and so on.

Today, where narrow borders are increasingly pursued, there is also a narrowing demand for borders of profiled areas of profiled screens. However, the width of the frame glue in the special-shaped area is slightly larger than that of the common area, and the width of the frame glue is slightly larger, so that a metal sparse area with corresponding width is required. In the metal sparse region, large pieces of metal have to be present. That is, a large block of metal that should be originally placed in this area, either broken up or removed, cannot be provided with a non-display area driving circuit, which is very disadvantageous for the realization of a narrow bezel.

Detailed Description

The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.

In the prior art, the width of the frame in the special-shaped area is generally larger than that of the conventional area, and in the setting process of the frame, light rays, such as ultraviolet rays, are required to be set from the outer side of the substrate of the base plate to cure the frame glue. In the plane parallel to the substrate of the substrate, the large-size metal in the substrate cannot be overlapped with the frame glue, otherwise, the curing light is blocked, the larger the frame glue width of the special-shaped area is, the wider the area where the large-size metal cannot be arranged is, the circuit which needs to be arranged in the area needs other space to be arranged, and the design of a narrow frame is very unfavorable. Under general conditions, the width of the frame glue in the special-shaped area is generally 1.1 times of that of the frame glue in the conventional area, which is not beneficial to the demand of people on the narrow frame in the special-shaped area.

In order to realize the narrow frame arrangement of the special-shaped area, the embodiment of the invention provides a display panel, which comprises:

a first substrate and a second substrate disposed opposite to each other; the first substrate includes a first substrate; the first substrate and the second substrate comprise at least one film layer;

a frame glue is arranged between the first substrate and the second substrate; the display panel comprises a display area and a non-display area surrounding the display area; the frame glue is arranged in the non-display area and surrounds the display area;

the edge of the display panel comprises a special-shaped edge; at least one pit is formed by digging at least one layer of film layer in the first substrate and/or the second substrate in the special-shaped edge area close to the special-shaped edge; the pits at least partially overlap the frame glue in a plane parallel to the first substrate.

In the embodiment of the invention, when the first substrate and the second substrate are oppositely arranged to form a box, a glue frame is required to be arranged between the first substrate and the second substrate, the frame glue is arranged at the edge of the display panel and surrounds the display area, when the display panel comprises the special-shaped edge, the frame glue is arranged in the special-shaped edge area along the special-shaped edge, in the special-shaped edge area, at least one film layer of at least one substrate of the first substrate and the second substrate is grooved to form a pit, and the pit is overlapped with the frame glue in a plane parallel to the first substrate of the first substrate, so that the frame glue at the special-shaped edge can overflow to the pit, thereby avoiding the problem of too wide frame glue caused by excessive frame glue in the special-shaped area, effectively realizing narrow frame arrangement, saving more non-display area space for circuit arrangement and improving the space utilization rate of the non-display area.

The foregoing is the core idea of the present invention, and the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without making any inventive effort are intended to fall within the scope of the present invention. It should be noted that the sealant is generally disposed in the liquid crystal panel (Liquid Crystal Display, LCD), and the technical scheme is explained by the basic structure of the liquid crystal display panel in this embodiment.

The display panel includes a display area AA and a non-display area NA, the non-display area NA is disposed around the display area AA, the non-display area NA is provided with a sealant 13 surrounding the display area AA, and the sealant 13 is used for bonding the first substrate 11 and the second substrate 12 and sealing the liquid crystal layer 14. As shown in fig. 1, the sealant 13 surrounds the edge region of the display panel to form a seal. In this embodiment, the display panel includes a shaped edge, and the pit 15 may be disposed on the shaped edge of the display panel. And the perpendicular projection of the pit 15 on the first substrate 111 overlaps with the frame glue 13. Then, as shown in fig. 2, the frame glue 13 overflows into the pit 15 before being cured, thereby reducing the width of the frame glue in the special-shaped edge area and facilitating the design of the narrow frame in the special-shaped edge area. In order to facilitate the display of the specific structures of the frame glue 13 and the pit 15, only the first substrate 11 is shown in fig. 1, and the structure of the second substrate 11 is omitted, but the cross-sectional structure in fig. 2 shows the structures of the first substrate 11 and the second substrate 12 at the same time, and the pit 15 is provided on the first substrate 11 for illustration. Fig. 3 is another schematic cross-sectional view of the display panel of fig. 1 along the line a-a ', and fig. 4 is another schematic cross-sectional view of the display panel of fig. 1 along the line a-a', however, as shown in fig. 3, the pits 15 may be disposed on the second substrate 12, or as shown in fig. 4, and the pits 15 may be disposed on the first substrate 11 and the second substrate 12, so as to further reduce the width of the sealant 13 in the shaped edge area, thereby further reducing the frame width in the shaped edge area. When forming the pit 15 on the substrate, at least one layer of the substrate may be grooved, as shown in fig. 2, two layers of the film on the substrate may be grooved to form the pit 15, as shown in fig. 3, and one layer of the film on the substrate may be grooved to form the pit 15. In addition, the pits 15 in fig. 2 to 4 are formed by digging through holes into some films, or may be formed by digging only a portion of some films, as shown in fig. 5, fig. 5 is another schematic cross-sectional view of the display panel along the line a-a' in fig. 1, and when the pits 15 are formed on the second substrate 12, a portion of some films may be formed by digging grooves into some films. Of course, in the cross section of the display panel, the pit 15 may be rectangular as shown in fig. 2 to 4, may be tapered as shown in fig. 5, or may be of other regular or irregular shape, and the specific shape of the pit 15 is not particularly limited in this embodiment.

In this embodiment, in the special-shaped edge area, one pit 15 may be provided, as shown in fig. 2 to 5, and a plurality of pits 15 may also be provided, as shown in fig. 6, fig. 6 is a schematic cross-sectional view of the display panel along line b-b' in fig. 1, and the number and the size of the pits 15 are not limited in particular, where the pits 15 may be provided in a plurality of smaller sizes.

As shown in fig. 10, fig. 10 is a schematic cross-sectional view of the first substrate along line a-a' in fig. 1, and optionally, the first substrate 11 may further include: an active layer 112 disposed on a side of the first substrate 111 adjacent to the second substrate; a gate insulating layer 113 disposed on a side of the active layer 112 away from the first substrate 111; a gate layer 118 disposed on a side of the gate insulating layer 113 away from the first substrate 111; at least one layer of interlayer insulating layer 114 disposed on a side of the gate layer 118 remote from the first substrate 111; a source/drain layer 115 disposed on a side of the interlayer insulating layer 114 away from the first substrate 111; a pixel electrode layer 116 disposed on a side of the source/drain layer 115 away from the first substrate 111; a planarization layer 117 disposed on a side of the pixel electrode layer 116 away from the first substrate 111; at least one of the planarization layer 117, the interlayer insulating layer 114, and the gate insulating layer 113 is grooved to form the pit 15.

When the pit 15 is disposed on the first substrate 11, at least one insulating layer in the first substrate 11 may be selected to be hollowed out or grooved. Alternatively, as shown in fig. 10, in a direction from the first substrate 11 toward the second substrate, the first substrate 11 is provided with: the first substrate 111, the active layer 112, the gate insulating layer 113, the gate layer 118, at least one layer of the layer-by-layer insulating layer 114, the source/drain layer 115, the pixel electrode layer 116 and the planarization layer 117, wherein the planarization layer 117 is used for providing a flat interface for one side of the first substrate 11 close to the second substrate so as to realize liquid crystal alignment between the first substrate 11 and the second substrate. In this embodiment, the insulating layer in the first substrate 11 includes at least the planarization layer 117, the interlayer insulating layer 114 and the gate insulating layer 113, and, as shown in fig. 10, the interlayer insulating layer 114 may include multiple layers, and at least one of the film layers may be grooved to form the pit 15, as shown in fig. 10, the planarization layer 117 and part of the interlayer insulating layer 114 may be grooved to form the pit 15, or, as shown in fig. 11, fig. 11 is another schematic cross-sectional view of the first substrate 11 along the line a-a' in fig. 1, the interlayer insulating layer 114 and the gate insulating layer 113 may be grooved, so that the pit 15 may be formed on the side of the planarization layer 117 close to the second substrate, and the frame glue 13 may be contained, thereby avoiding the problem that the width of the frame glue set in the special-shaped edge region is too large, and realizing the narrow frame setting of the display panel.

As shown in fig. 12 and 13, fig. 12 is a schematic cross-sectional view of the second substrate along line a-a 'in fig. 1, and fig. 13 is another schematic cross-sectional view of the second substrate along line b-b' in fig. 1, where, optionally, the second substrate 12 may include: a second substrate 121; a black matrix layer 122 disposed on a side of the second substrate 121 adjacent to the first substrate 11; the color resistance layer 123 is arranged on one side of the second substrate 121 close to the first substrate; at least one of the color resist layer 123 and the black matrix layer 122 is grooved to form pits 15.

When the pit 15 is disposed on the second substrate 12, at least one insulating layer in the second substrate 12 may be selected to be hollowed or grooved. Alternatively, as shown in fig. 10, in a direction from the second substrate 12 toward the first substrate, the second substrate 12 is provided with: a second substrate 121, a black matrix layer 122, and a color resist layer 123. For example, as shown in fig. 12 and 13, only the color-removal resist layer 123 may be hollowed out to form the pit 15, and one or more pits 15 may be disposed in the pit 15, and, as shown in fig. 14, fig. 14 is another schematic cross-sectional view of the second substrate along line b-b' in fig. 1, the color-removal resist layer 123 and a portion of the black matrix layer 122 may be hollowed out to form the pit 15, but it should be noted that the black matrix layer 122 may not be hollowed out, otherwise, the non-display area NA of the second substrate 12 may have a problem of light leakage, and in this embodiment, the pit 15 is formed in the second substrate 12 through the film layers such as the color-removal resist layer 123 and the black matrix layer 122, and the frame glue 13 may be contained as well, so that the problem of excessively large frame glue width disposed in the special-shaped edge area is avoided, and the narrow frame arrangement of the display panel is realized.

With continued reference to fig. 1, optionally, the edge of the display panel may further include: a conventional edge 11f; the shaped edge region is formed with a pit region 15a; the pit area 15a is provided with one first pit 151; in a plane parallel to the first substrate 111, the first pit 151 coincides with the pit area 15a; alternatively, the pit area 15a is provided with a plurality of second pits 152; the pattern surrounded by the edges of the pit set formed by the plurality of second pits 152 coincides with the pit area 15 a.

As shown in fig. 1, in the present embodiment, the special-shaped edge and the regular edge 11f of the display panel are provided with the pit area 15a, and the regular edge area may not be provided with pits, in this embodiment, each special-shaped edge area corresponds to one pit area 15a, when only one pit 15 is provided in the pit area 15a, the vertical projection of the pit 15 on the first substrate 11 may coincide with the pit area 15a, which is called a first pit 151, that is, the size of the first pit 151 on the plane of the first substrate 11 is the same as that of the pit area 15a, and when the pit area 15a is provided with a plurality of pits 15, the pattern surrounded by the edges of the pit set formed by the plurality of pits 15 coincides with the pit area 15a, and such a pit 15 is called a second pit 152. For the pit areas 15a of the same area, the size of the second pits 152 is set smaller than that of the first pits 151. It should be noted that, in this embodiment, whether the first pit 151 or the second pit 152 may accommodate the sealant 13 in the special-shaped edge area, so as to reduce the width of the sealant 13 in the special-shaped edge area, reduce the width of the frame of the special-shaped edge, and preferably, through the arrangement of the first pit 151 or the second pit 152, the width of the sealant of the special-shaped edge is consistent with the width of the sealant of the conventional edge, so that the width of the frame is uniform while the narrow frame is ensured, and the viewing experience of the panel is improved.

Fig. 15 is an enlarged schematic view of the area A1 in fig. 8, and optionally, in a plane parallel to the first substrate 111, an edge of the pit area 15a away from the display area AA is disposed on a side of the frame adhesive 13 away from the display area AA, where the edge is away from the display area AA; the edge of the pit area 15a near the display area AA is disposed on one side of the frame glue 13 near the display area AA near the edge of the display area AA.

In this embodiment, the frame glue 13 is disposed along the edge of the display panel, in this embodiment, the pit area 15 may also be disposed along the edge of the display panel, for example, for the arc-shaped special-shaped edge shown in fig. 15, a fan-shaped pit area 15a may be disposed, so that the front projection of the pit area 15a on the first substrate 111 may cover the frame glue 13 away from the edge of the display area AA, or cover the frame glue 13 near the edge of the display area AA, that is, in the direction from the display area AA to the edge of the display panel vertically, the width of the pit area 15a is greater than the width of the frame glue 13, which is further beneficial to overflow a large amount of frame glue 13 into the pit, and avoid the excessive width of the frame glue at the special-shaped edge.

Fig. 16 is a schematic view of another enlarged structure of the area A1 in fig. 8, and optionally, in a plane parallel to the first substrate 111, an edge of the pit area 15a away from the display area AA is disposed on a side of the frame glue 13 away from the edge of the display area AA and close to the display area AA; the edge of the pit area 15a near the display area AA is disposed on one side of the frame glue 13 near the display area AA near the edge of the display area AA.

In this embodiment, for the arc-shaped special-shaped edge shown in fig. 15, a fan-shaped pit area 15a may be also provided, so that the front projection of the pit area 15a on the first substrate 111 may not cover the edge of the frame glue 13 away from the display area AA, and cover the edge of the frame glue 13 close to the display area AA.

Fig. 17 is a schematic diagram of another enlarged structure of the area A1 in fig. 8, and optionally, in a plane parallel to the first substrate 111, an edge of the pit area 15a away from the display area AA is disposed on a side of the frame glue 13 away from the display area AA, where the edge is away from the display area AA; the edge of the pit area 15a near the display area AA is disposed on one side of the frame glue 13 near the edge of the display area AA and far from the display area AA.

In this embodiment, the orthographic projection of the pit area 15a on the first substrate 111 may cover the edge of the frame glue 13 away from the display area AA, and the edge of the frame glue 13 close to the display area AA is not covered. In addition, the sequence of the frame glue 13 and the pit area 15a in the direction perpendicular to the first substrate 111 may be arbitrarily exchanged, as shown in fig. 15 and 17, the frame glue 13 may be disposed on a side of the pit area 15a away from the first substrate 111, or the pit area 15a may be disposed on a side of the frame glue 13 away from the first substrate 111.

Fig. 18 is a schematic view of another enlarged structure of the area A1 in fig. 8, and optionally, in a plane parallel to the first substrate 111, an edge of the pit area 15a away from the display area AA is disposed on a side of the frame glue 13 away from the edge of the display area AA and close to the display area AA; the edge of the pit area 15a near the display area AA is disposed on one side of the frame glue 13 near the edge of the display area AA and far from the display area AA.

In this embodiment, the orthographic projection of the sealant 13 on the first substrate 111 covers the side of the pit area 15a far from the display area AA and the side close to the display area AA, and this arrangement is also beneficial to overflowing a large amount of sealant 13 into the pit, so as to avoid the excessive sealant width at the special-shaped edge. In addition, the pit area 15a does not occupy other areas except the frame glue 13 in a plane parallel to the first substrate 111, so that the frame glue 13 and the pit area 15a occupy the same horizontal area while avoiding the too wide frame, and the frame width of the display panel is reduced, thereby realizing the narrow frame design.

Fig. 19 is a schematic view of another enlarged structure of the area A1 in fig. 8, and optionally, the pit area 15a may be provided with a plurality of second pits 152; the width of the frame glue 13 gradually increases in the direction from the regular edge region toward the profiled edge region (the arrow direction in fig. 19); the capacity of the second pit 152 gradually increases. In this embodiment, since the frame glue exit speed of the nozzle for coating the frame glue 13 is uniform, when the frame glue is sprayed along the regular edge, the speed is uniform, so the width of the frame glue 13 is the same, and when the frame glue is coated to the irregular edge, the advancing speed of the nozzle is reduced, so that the width of the frame glue in the irregular edge area is increased, in the direction from the regular edge area to the irregular edge area, the pit capacity needs to be further increased, that is, the capacity of the second pit 152 is gradually increased, so as to reduce the width of the frame glue 13 in the irregular edge area, and realize the narrow frame design. The capacity of the second recess 152 gradually increases and then gradually decreases from the C1 end to the C2 end of the frame adhesive 13.

The pit capacity may be set by parameters such as pit radial dimension, depth, and set density, with continued reference to fig. 19, and optionally, the radial dimension of the second pit 152 may be gradually increased in a direction from the regular rim area toward the profiled rim area (arrow direction in fig. 19). The width of the frame adhesive 13 in the special-shaped edge area is reduced, and the narrow frame design is realized. The radial dimension d of the second recess 152 gradually increases and then gradually decreases from the C1 end to the C2 end of the frame glue 13.

Fig. 20 is a schematic view of another enlarged structure of the area A1 in fig. 8, and optionally, the number and/or density of the second pits 152 is gradually increased in a direction from the regular edge area toward the irregular edge area (an arrow direction in fig. 20). The width of the frame glue 13 in the special-shaped edge area can be reduced, and the narrow frame design is realized. The number or density of the second recesses 152 gradually increases and then gradually decreases from the C1 end to the C2 end of the frame adhesive 13. In addition, optionally, in the direction from the regular edge area to the special-shaped edge area, the setting depth of the second pit 152 may be gradually increased, and similarly, the capacity of the pit may be gradually increased in the direction from the regular edge area to the special-shaped edge area, so as to implement the narrow frame design of the special-shaped edge area.

Fig. 21 is another enlarged schematic structural view of the area A1 in fig. 8, and fig. 22 is another enlarged schematic structural view of the area A1 in fig. 8, optionally, the shaped edge area of the first substrate 11 may be further provided with a gate driving circuit, for example, ASGs shown in fig. 21 and 22; in a plane parallel to the first substrate 111, the projection of the pit 15 does not overlap with the gate driving circuit. Because the pit 15 needs to accommodate the plastic frame, the area covered by the projection of the pit 15 on the first substrate 11 cannot be provided with a large metal, and the gate driving circuit on the first substrate 11 and the front projection of the pit 15 on the first substrate 111 do not overlap, for example, as shown in fig. 21, the gate driving circuit is disposed on the side of the pit 15 close to the display area AA, or as shown in fig. 22, the gate driving circuit is disposed in the gap area between the pits 15, so as to avoid the problem that the plastic frame cannot be cured.

The embodiment of the invention also provides a display device. Fig. 23 is a schematic structural diagram of a display device according to an embodiment of the present invention, and as shown in fig. 23, the display device according to the embodiment of the present invention includes a display panel 1 according to any embodiment of the present invention.
