All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application. Furthermore, it should be understood that the detailed description is presented herein for purposes of illustration and explanation only and is not intended to limit the present application. In this application, unless otherwise indicated, terms of orientation such as "upper" and "lower" are used to generally refer to the upper and lower positions of the device in actual use or operation, and specifically the orientation of the drawing figures; while "inner" and "outer" are for the outline of the device.
The embodiment of the application provides a display panel and a display device. The following will describe in detail. The following description of the embodiments is not intended to limit the preferred embodiments.
Firstly, the embodiment of the application provides a display panel, which comprises a display area and a non-display area, wherein the display area is provided with a first slit, and the first slit extends along the non-display area and is close to the edge of the display area; the first slits comprise a plurality of sections of first sub-slits, the sections of first sub-slits are distributed in sequence along the length direction of the first slits, and a first gap is reserved between every two adjacent sections of first sub-slits.
Fig. 1 is a schematic structural diagram of a display panel provided in an embodiment of the present application, as shown in fig. 1, a display panel 100 includes a display area 110 and a non-display area 120, where the display area 110 is provided with main functional film layers such as a thin film transistor layer and a light emitting layer, so as to realize different display requirements of the display panel 100. The non-display area 120 is mainly designed to be different shapes according to the usage requirement of the display panel 100, so as to meet the application requirement of the display panel 100.
It should be noted that the display area 110 may partially surround the non-display area 120, where the non-display area 120 may be cut into a U-shape, a circular shape, a water drop shape or other types according to the requirement, and the specific shape thereof may be adjusted according to the actual design requirement, which is not limited herein.
As shown in fig. 2 and 3, the non-display area 120 is provided with a first slit 121, and the first slit 121 extends along the non-display area 120 near the edge of the display area 110. That is, the extending direction of the first slit 121 is consistent with the extending direction of the connecting edge of the non-display area 120 and the display area 110, so as to effectively isolate the path of the vapor diffusing from the non-display area 120 to the display area 110 when the non-display area 120 is cut, and prevent the vapor from invading the organic film layer in the display area 110, thereby affecting the overall display effect of the display panel 100.
Optionally, the first slit 121 includes multiple sections of first sub-slits 1211, the multiple sections of first sub-slits 1211 are sequentially distributed along the length direction of the first slit 121, and a first gap 1212 is formed between two adjacent sections of first sub-slits 1211. That is, the first slit 121 is not a continuous whole but is broken into multiple segments, so that the situation that the stress cannot be released in time to break when the non-display area 120 is cut into the target shape due to the overlong first sub-slit 1211 is avoided, and at this time, water vapor gradually invades into the organic film layer in the display area 110 along the breaking opening, so that the organic film layer absorbs water and deteriorates, thereby affecting the normal operation of the display panel 100.
It should be noted that, the first slit 121 is a groove structure formed on the display panel 100, and the groove depth of the first slit 121 may be designed to penetrate through the entire thin film transistor layer and even partially penetrate into the substrate, i.e. the bottom surface of the groove of the first slit 121 is the substrate, so as to ensure that the first slit 121 can effectively isolate the intrusion of water vapor into the organic film layer of the display area 110, and improve the stability of the display panel 100.
The area where the first slit 121 is located is formed by an inorganic film layer, that is, in the process of manufacturing the display panel 100, the organic film layer or the metal film layer in the area where the first slit 121 is located is etched, so that the first slit 121 only needs to pass through the inorganic film layer in the process of manufacturing, and the unstable manufacturing process caused by the energy difference required to pass through the organic film layer, the inorganic film layer or the metal film layer in the process of manufacturing is avoided, thereby causing the unstable structure of the first slit 121. Therefore, the region where the first slit 121 is located is designed to be composed of an inorganic film layer, which is advantageous for improving process stability and stress release of the first slit 121 during dicing.
According to the embodiment of the application, the first slit 121 is arranged in the non-display area 120, the first slit 121 extends along the edge of the non-display area 120, which is close to the display area 110, and the first slit 121 comprises a plurality of sections of first sub-slits 1211, and a first gap 1212 is formed between two adjacent sections of first sub-slits 1211, so that the situation that the stress on the first slit 121 cannot be effectively released to break when the non-display area 120 is cut due to overlong first slit 121 can be avoided, and therefore, the vapor is prevented from gradually invading to an organic film layer in the display area 110 along a breaking opening, and the overall stability of the display panel 100 is improved.
Optionally, the non-display area 120 is sequentially provided with a plurality of first slits 121 along a direction away from the display area 110, and the extending directions of the plurality of first slits 121 are consistent with the extending directions of the connecting edges of the non-display area 120 and the display area 110, so that when the non-display area 120 is cut, the path of water vapor diffusing to the display area 110 along the non-display area 120 can be further isolated, and when a certain first slit 121 breaks, the water vapor directly invades the display area 110, thereby ensuring the display effect of the display panel 100.
The structural design and mutual coordination of the plurality of first slits 121 can be adjusted according to the actual design requirement, and only the paths of the vapor diffusing along the non-display area 120 to the display area 110 need to be ensured when the plurality of first slits 121 can effectively isolate the non-display area 120 for cutting.
Optionally, at least one first slit 121 of the plurality of first slits 121 has a plurality of first gaps 1212, i.e. at least one first slit 121 comprises at least three segments of first sub-slits 1211. Dividing the first slit 121 into at least three sections of first sub-slits 1211 may further reduce the length of each section of first sub-slit 1211, which may facilitate the release of stress on each section of first sub-slit 1211, and avoid the breakage of the first sub-slit 1211 due to stress concentration.
In some embodiments, the lengths of the first sub-slits 1211 of each segment are equal, that is, the first slits 121 are equally divided by the plurality of first gaps 1212, and the equally dividing manner is convenient for structural design of the first slits 121 according to the requirement, and the design manner is simple, which is beneficial to simplifying the process flow.
In other embodiments, the lengths of the first sub-slits 1211 of each segment are not completely equal, and the position of the first gap 1212 may be optimally adjusted according to the stress distribution situation on the first slit 121 during the practical application when the first slit 121 is structurally designed.
Providing more first gaps 1212 for areas where stresses are greater or are more likely to concentrate, making the number of first sub-slits 1211 in this area greater; for a region of relatively low stress, then, fewer first gaps 1212 may be provided, such that the length of the first sub-slit 1211 of that region is relatively long. By adopting the design mode, the risk of breakage of the first slit 121 due to stress concentration can be reduced to the greatest extent, and the whole manufacturing process is prevented from being too complex, so that the feasibility of the manufacturing process is ensured and the overall stability of the display panel 100 is improved.
Optionally, in this embodiment, each first slit 121 has a plurality of first gaps 1212, that is, each first slit 121 is divided into at least three segments of first sub-slits 1211, so as to further reduce the risk of breakage of each first slit 121 due to stress concentration. When a gap appears in one of the first slits 121, moisture enters the display area 110 along the gap, and the adjacent first slits 121 block further entry of moisture, so as to ensure the overall display effect of the display panel 100.
Optionally, the first gaps 1212 of two adjacent first slits 121 are arranged in a staggered manner, that is, the first gaps 1212 of two adjacent first slits 121 are not mutually communicated, and the first gaps 1212 are connected with the side walls of the adjacent first slits 121.
It should be noted that, if the first gaps 1212 of the adjacent first slits 121 are connected to each other, that is, the first gaps 1212 of the corresponding positions of the first slits 121 are connected as a whole and extend along the distribution direction of the first slits 121, the stress on the first slits 121 will be concentrated at a certain position for releasing, and the stress distribution on each first slit 121 is different, which is not beneficial to the overall stress release, and there is still a risk of breaking.
In addition, since the first gaps 1212 of the adjacent first slits 121 are connected to each other, when a crack occurs in the first gap 1212 of one of the first slits 121, moisture gradually invades the display region 110 directly along the connected first gap 1212, resulting in water absorption failure of the organic film layer of the display region 110.
Therefore, the first gaps 1212 of two adjacent first slits 121 are arranged in a staggered manner, which not only can further reduce the risk of breakage of the first slits 121 due to stress concentration, but also can effectively avoid the invasion of water vapor to the organic film layer of the display area 110 due to the occurrence of cracks on the first gaps 1212, thereby improving the overall stability of the display panel 100.
The first gaps 1212 of the plurality of first slits 121 may be all arranged in a staggered manner, that is, the arrangement positions of the first gaps 1212 of each first slit 121 are different; of course, the setting positions of the first gaps 1212 of the first slits 121 that are disposed at intervals can be the same, and the specific setting manner thereof can be adjusted according to the actual design requirement.
In some embodiments, the first gaps 1212 of the first slits 121 include first and second positions, the positions of the first gaps 1212 of adjacent first slits 121 being alternately distributed according to the first and second positions; the setting position of the first gap 1212 of each first slit 121 can be adjusted according to the actual stress distribution, which only needs to ensure that the vapor cannot gradually diffuse along the first gap 1212 to the organic film layer of the display area 110, which is not limited in particular.
Optionally, the non-display area 120 includes a cutting area 122, and the cutting area 122 is located at a side of the first slit 121 away from the display area 110. The cutting area 122 is used for cutting the display panel 100 into a desired shape during the manufacturing process of the display panel 100; because of the precision requirement of the cutting device, the cutting area 122 has a certain size range, so that the cutting to the non-cutting area 122 during the manufacturing process is prevented from affecting the manufacturing process of the display panel 100.
Optionally, a plurality of second slits 1221 are provided in the cutting region 122. In the cutting process, substances such as water vapor may be introduced into the edge of the cutting area 122, and the plurality of second slits 1221 are disposed in the cutting area 122, so that the water vapor is prevented from diffusing along the cutting area 122 toward the display area 110, and the risk of intrusion of the water vapor into the organic film layer of the display area 110 is further reduced, thereby improving the stability of the display panel 100.
The plurality of second slits 1221 in the cutting area 122 can provide a cutting precision range for the cutting device, that is, the cutting device can cut in the set second slits 1221, so as to avoid the deviation of the cutting device from the non-cutting area 122 due to the influence of the cutting precision, thereby ensuring the smooth process of the display panel 100.
In some embodiments, as shown in fig. 2, the second slits 1221 extend continuously along the length of the first slits 121, i.e., the second slits 1221 are one continuous unit. Since the second slits 1221 are provided in the cutting zone 122, the cutting device mainly performs cutting along the direction in which the groove structures of the second slits 1221 are provided.
If the second slit 1221 does not extend continuously, a boss structure having a thickness different from that of the second slit 1221 may be formed when the cutting device performs cutting, and the energy required for cutting the different thickness by the cutting device may be different; if the initial setting energy of the cutting device is smaller, the problem that the cutting area 122 is not cut off occurs, and if the initial setting energy needs to be set to a larger value to ensure that the cutting area 122 is cut off smoothly, the energy is wasted, and the production cost is increased.
Therefore, the second slits 1221 are provided to extend continuously along the length direction of the first slits 121, so that not only can the effective cutting of the cutting area 122 be ensured, but also the waste of energy can be avoided, and the production cost can be saved.
In other embodiments, as shown in fig. 3, the second slit 1221 includes multiple sections of second sub-slits 1221a, where the multiple sections of second sub-slits 1221a are distributed in sequence along the length direction of the first slit 121, and a second gap 1221b is formed between two adjacent sections of second sub-slits 1221 a.
The second slits 1221 are disposed in the cutting area 122, and stress concentration is easily generated at the cutting edge during cutting, so that the second slits 1221 are broken, and moisture may diffuse along the second slits 1221 to the display area 110, thereby affecting the display performance of the display panel 100. Therefore, the second slits 1221 are configured as the multi-stage second sub-slits 1221a, so that the breakage of the display panel 100 caused by the stress that cannot be released in time due to the overlong second slits 1221 can be effectively avoided, thereby improving the stability of the display panel.
The second gaps 1221b of the adjacent second slits 1221 are arranged in a staggered manner, that is, the second gaps 1221b of the adjacent two second slits 1221 are not mutually communicated, and the second gaps 1221b are connected with the side walls of the adjacent second slits 1221.
It should be noted that, if the second gaps 1221b of the adjacent second slits 1221 are connected to each other, that is, the second gaps 1221b of the corresponding positions of the plurality of second slits 1221 are connected as a whole, the stress on the second slits 1221 will be concentrated at a certain position to release, and the stress distribution on each second slit 1221 is different, which is not beneficial to the overall stress release, and still there is a risk of breaking.
In addition, since the second gaps 1221b of the adjacent second slits 1221 are connected to each other, when a crack occurs in the second gap 1221b of one of the second slits 1221, moisture gradually intrudes into the display region 110 directly along the connected second gap 1221b, resulting in water absorption failure of the organic film layer of the display region 110.
Therefore, the second gaps 1221b of two adjacent second slits 1221 are arranged in a staggered manner, which not only can further reduce the risk of breakage due to stress concentration during the cutting of the second slits 1221, but also can effectively avoid the invasion of water vapor into the organic film layer of the display area 110 due to the occurrence of cracks on the second gaps 1221b, thereby improving the overall stability of the display panel 100.
Optionally, the length directions of at least two sections of the first sub-slits 1211 in the first slit 121 are disposed at an included angle. I.e. the first gap 1212 between at least two segments of first sub-slits 1211 is arranged at the corner between two segments of first sub-slits 1211. In the manufacturing process of the display panel 100, the stress at the corner of the first slit 121 is more concentrated than that at other areas, and the first gap 1212 is disposed at the corner of the first slit 121, which is beneficial to releasing the stress on the first slit 121 and avoiding the break at the corner due to the overlarge stress.
The size of the included angle formed by the length direction of the at least two sections of the first sub-slits 1211 can be adjusted according to the actual design requirement, and the number of the included angles can also be adjusted and designed according to the shape of the non-display area 120, which is not particularly limited herein.
Optionally, the edge of the non-display area 120 adjacent to the display area 110 includes two opposite first side edges 123, and a second side edge 124 connected between the two first side edges 123. That is, the edges of the non-display region 120 near the display region 110 are in a "U" -like structure, and when such a structure is adopted, the non-display region 120 can be disposed in the middle region of the end portion of the display panel 100, which contributes to improving the overall aesthetic appearance of the display panel 100. In the actual manufacturing process, the specific shape and the setting position of the non-display area 120 can be adjusted according to the design requirement, which is not particularly limited herein.
Optionally, the first gap 1212 of the at least one first slit 121 corresponds to the location of the junction of the first side edge 123 and the second side edge 124, i.e. the first gap 1212 of the at least one first slit 121 is located at the corner between the first side edge 123 and the second side edge 124. In the manufacturing process of the display panel 100, the stress at the corner of the first slit 121 is more concentrated than that at other areas, and the first gap 1212 is disposed at the corner of the first slit 121, which is beneficial to releasing the stress on the first slit 121 and avoiding the break at the corner due to the overlarge stress.
Optionally, the connection between the two first side edges 123 and the second side edges 124 forms two corners, and in this embodiment, the first gaps 1212 are disposed at the two corners, so that the release of stress on the first slit 121 can be further promoted by this structural design, and the breakage of a corner caused by excessive stress is avoided, thereby ensuring the display effect of the display panel 100.
Besides the first gap 1212 is disposed at the connection between the first side edge 123 and the second side edge 124, one or more first gaps 1212 may be disposed at the corresponding positions of the first side edge 123 in the extending direction, so as to divide the first slit 121 corresponding to the extending direction of the first side edge 123 into multiple segments, thereby further relieving the stress release on the first slit 121 corresponding to the extending direction of the first side edge 123 and improving the stability of the display panel 100.
Optionally, the first gap 1212 of the at least one first slit 121 corresponds to the position of the second side edge 124. I.e. along the direction in which the second side edge 124 extends, at least one first gap 1212 is provided, and the first slit 121 comprises a plurality of segments of first sub-slits 1211 along the direction in which the second side edge 124 extends. The first gap 1212 corresponds to the second side edge 124, which means that the first gap 1212 is disposed at a position along the extending direction of the second side edge 124, that is, the first gap 1212 is located between the two first side edges 123.
In the practical application process, the length of the first slit 121 along the extending direction of the second side edge 124 is greater than the length of the first slit 121 along the extending direction of the first side edge 123, so that stress concentration is more likely to be formed in the extending direction of the first slit 121 along the second side edge 124, and the first slit 121 is divided into multiple sections of first sub-slits 1211 along the extending direction of the second side edge 124, which is helpful for releasing the stress of the whole first slit 121, and further reduces the risk of breakage of the first slit 121 during the manufacturing process of the display panel 100.
Alternatively, the non-display area 120 is provided with a blocking portion 125, the blocking portion 125 extends continuously along the length direction of the first slit 121, and the blocking portion 125 is located between the first slit 121 and the display area 110. In the manufacturing process of the display panel 100, when the first slit 121 breaks or cracks, water vapor gradually diffuses toward the display area 110 along the cracks, and by disposing the blocking portion 125 between the first slit 121 and the display area 110, the water vapor can be prevented from directly entering the display area 110 through the first slit 121, thereby improving the overall stability of the display panel 100.
Optionally, the non-display area 120 is further provided with a third slit 126, and the third slit 126 extends continuously along the length direction of the first slit 121. In this embodiment, the third slit 126 is disposed at the edge of the blocking portion 125, and the arrangement of the third slit 126 can further reduce the risk that water vapor propagates to the blocking portion 125 along the crack on the first slit 121 or the second slit 1221 and then enters the display area 110, thereby ensuring the display effect of the display panel 100.
Optionally, the third slit 126 is located at a side of the barrier 125 near the display area 110, that is, the third slit 126 is located between the barrier 125 and the display area 110, when moisture propagates to the barrier 125 along the crack on the first slit 121 or the second slit 1221, the third slit 126 can serve as another defense line to prevent the moisture from diffusing from the barrier 125 to the display area 110, thereby improving the overall stability of the display panel 100.
Optionally, the third slit 126 is located at a side of the blocking portion 125 away from the display area 110, that is, the third slit 126 is located between the blocking portion 125 and the first slit 121, and this structural design can provide a line of defense between the blocking portion 125 and the first slit 121 to prevent water vapor from diffusing from the first slit 121 to the blocking portion 125, thereby improving the overall stability of the display panel 100.
Optionally, the third slit 126 is disposed at one side of the blocking portion 125 close to the display area 110 and one side of the blocking portion 125 far away from the display area 110, that is, the third slit 126 forms a protection line at two sides of the blocking portion 125, so as to further prevent intrusion of water vapor into the organic film layer of the display area 110, and effectively improve the overall stability of the display panel 100.
