On display devices such as mobile phones and tablet computers, it is necessary to integrate optical elements such as a front camera, an infrared light sensor, a proximity light sensor, and the like on the side where the display panel is provided. In some embodiments, the aperture area KA may be disposed on the display device, and the optical element is disposed on the back of the aperture area KA, so as to realize full-screen display of the display panel under the condition that the optical element is ensured to work normally.
However, due to the limitation of the current display panel structure, when the filling medium 4 disposed in the hole area KA is too much, the glue material may jump over the transition area NA and enter the display area AA, and when the glue material is cured, the device in the display area is damaged, which affects the display effect and reduces the production yield.
In order to solve the above problems, embodiments of the present invention provide a display panel and a display device, and the following describes embodiments of the display panel and the display device with reference to the accompanying drawings.
The display panel provided by the embodiment of the invention can be an Organic Light-Emitting Diode (OLED) display panel, a liquid crystal panel or a Micro flat display panel (Micro-OLED or Micro-LED), and the like.
Referring to fig. 1 to 8, a display panel 100 having an aperture area KA, a display area AA at least partially surrounding the aperture area KA, and a transition area NA between the aperture area KA and the display area AA is provided in an embodiment of the invention. The display panel 100 includes: the device comprises a base plate 1, a cover plate 3 and a supporting structure 2, wherein the cover plate 3 is arranged opposite to the base plate 1; the supporting structure 2 is arranged between the substrate 1 and the cover plate 3 and is used for supporting the cover plate 3 and the substrate 1; the support structure 2 comprises at least one first support 21 arranged in the transition area NA, the first support 21 being arranged around the aperture area KA; the surface of the cover plate 3 opposite to the substrate 1 and/or the surface of the substrate 1 opposite to the cover plate 3 are provided with accommodating grooves 31 for accommodating the first supports 21. Optionally, the space enclosed by the base plate 1, the first support 21 and the cover plate 3 is used for accommodating the filling medium 4.
The display panel 100 according to the embodiment of the invention includes a substrate 1, a supporting structure 2, and a cover plate 3, wherein the supporting structure 2 includes at least one first supporting member 21 disposed in a transition area NA. The display area AA is disposed at least partially around the aperture area KA, and optical elements such as a camera and a fingerprint recognition element are disposed corresponding to the aperture area KA. In order to realize a full screen, in an embodiment of the present invention, the transition area NA is disposed around the aperture area KA, and a blind hole is disposed between the substrate 1 and the cover plate 3. In order to ensure that no Newton's rings and no excessively high transmittance occur in the region where the blind via is formed, a filling medium 4 needs to be provided in the region where the blind via is formed. When the filling medium 4 is formed, the filling medium 4 has a certain fluidity and may be filled too much, so that the medium may jump over the transition area NA and enter the display area AA, and the display area AA is damaged, thereby affecting the display effect and reducing the production yield.
In view of the above problem, in the embodiment, when the filling medium 4 is disposed in the area surrounded by the substrate 1, the first supporting member 21 and the cover plate 3, the disposed first supporting member 21 and the accommodating groove 31 can block the filling medium 4, so as to effectively prevent the filling medium 4 from entering the display area AA.
Further, the surface of the cover plate 3 opposite to the substrate 1 and/or the surface of the substrate 1 opposite to the cover plate 3 are provided with a receiving groove 31 for receiving the first supporting member 21, specifically, the receiving groove 31 may be disposed on the cover plate 3, the substrate 1, or both the cover plate 3 and the substrate 1, without any particular limitation, and fig. 2 only illustrates that the receiving groove 31 is disposed on the cover plate 3.
The receiving groove 31 may be configured to receive a portion of the first support 21, such that the first support 21 is engaged with the cover plate 3 or the base plate 1, and this structure helps to improve the blocking effect of the first support 21 and the stability of the support. Specifically, the first supporting member 21 may partially extend into the receiving groove 31, and when the display panel is provided with the filling medium 4, the first supporting member 21 and the receiving groove 31 may limit a flow path of the filling medium 4 together, that is, not only the first supporting member 21 may block the filling medium 4, but also a part of the cover plate 3 or the substrate 1 forming the receiving groove 31 may also block the filling medium 4 after the first supporting member 21 is embedded with the cover plate 3 or the substrate 1. On the other hand, the receiving groove 31 may also receive a portion of the redundant filling medium 4, so as to further prevent the filling medium from flowing to the display area AA, thereby ensuring the production yield of the display panel 100.
It is understood that the first support 21 is disposed around the aperture area KA, and the first support 21 is disposed around the aperture area KA in a closed ring shape or in a semi-closed ring shape, so that when the first support 21 is in a closed ring shape, the filling medium 4 corresponding to the aperture area KA can be better blocked from flowing to the display area AA. The specific shape of the first support 21 can be selected according to the actual conditions of the aperture area KA, such as circular shape, drop shape, etc.
Optionally, the display panel further includes a filling medium 4, the filling medium 4 is disposed in a space surrounded by the substrate 1, the cover plate 3 and the first support 21, a material of the filling medium 4 is not particularly limited, and specifically, a material such as resin and organic glue may be used, and in this embodiment, the filling medium 4 is exemplified as a filling glue with high light transmittance. Specifically, the filling medium 4 may be made of a transparent Adhesive material such as OCA (optical Clear Adhesive) to ensure the light transmittance of the hole area KA.
Referring to fig. 2 and 3, alternatively, a circle of the first supporting member 21 may be disposed around the aperture area KA, or a plurality of circles of the first supporting member 21 may be disposed.
In order to make the first supporting member 21 have a sufficient length to block the filling medium 4 when the filling medium 4 is disposed on the display panel, the supporting structure 2 further includes a plurality of second supporting members 22 disposed in the display area AA, and a length ratio between the first supporting member 21 and the second supporting member 22 in a direction perpendicular to a plane of the substrate 1 is not greater than 5: 1.
It should be noted that, because the portion of the first supporting member 21 higher than the second supporting member 22 needs to extend into the receiving groove 31, the first supporting member 21 is higher than the second supporting member 22, the depth of the corresponding receiving groove 31 is larger, the space of the receiving groove 31 is larger, and more redundant filling mediums 4 can be received, of course, because the receiving groove 31 is opened in the cover plate 3, the depth of the receiving groove 31 is too large, which also affects the structural strength of the cover plate 3, and meanwhile, the length of the first supporting member 21 is too large, which may also affect the connection stability thereof. Optionally, the length ratio between the first support 21 and the second support 22 is equal to 1.2:1, 1.5:1, 1.8:1, 2:1, 2.5:1, 3:1, 3.5:1, 4:1, or 5:1, so as to achieve blocking of the filling medium 4 while ensuring structural stability.
In some alternative embodiments, the difference in length between the first support 21 and the second support 22 in the direction perpendicular to the plane of the substrate 1 is less than or equal to the depth of the accommodating groove 31.
When the filling medium 4 is disposed on the display panel, in order to achieve a blocking effect for the filling medium 4 and to accommodate a portion of the filling medium 4, the depth of the accommodating groove 31 may be set to be slightly greater than a length difference between the first supporting member 21 and the second supporting member 22, so that more filling medium 4 may be left in the accommodating groove 31. Optionally, the length difference between the first support 21 and the second support 22 is equal to the depth of the receiving groove 31, so that the first support 21 just contacts with the bottom wall of the receiving groove 31, and the tightness of blocking the filling medium 4 is ensured.
Referring to fig. 4, in order to further improve the blocking effect of the first supporting member 21, in some optional embodiments, the display panel 100 further includes a third supporting member 23 located in the transition area NA, the third supporting member 23 is disposed on a side of the first supporting member 21 away from the second supporting member 22, that is, the third supporting member 23 is disposed between the first supporting member 21 and the filling medium 4, and in a direction perpendicular to the plane of the substrate 1, a length of the third supporting member 23 is greater than a length of the second supporting member 22 and less than or equal to a length of the first supporting member 21.
It should be noted that, when the display panel is provided with the filling medium 4, the third supporting member 23 is disposed between the first supporting member 21 and the filling medium 4, and a part of the filling medium 4 may be blocked by the third supporting member 23. In some alternative embodiments, when the length of the third support 23 is less than the length of the first support 21, a portion of the filling medium 4 may pass over the third support 23 into the region between the third support 23 and the first support 21, increasing the storage space for the excess filling medium 4. Meanwhile, the third support 23 can release the gas in the hole area KA, so that bubbles are prevented from being generated in the hole area KA after the filling medium 4 is arranged.
In some alternative embodiments, the third support 23 is in the form of a closed ring disposed around the aperture area KA. Optionally, the third support 23 and the first support 21 form a concentric ring arranged around the aperture area KA to achieve a multi-pass barrier for the filling medium 4.
Referring to fig. 5 and 6, since the cross-sectional path B-B in fig. 5 passes through the opening 231 on the left side of the aperture area KA, the third support 23 is not shown on the left side of the aperture area KA in the cross-sectional view of fig. 6, and the third support 23 is shown only on the right side of the aperture area KA.
In order to uniformly distribute the excess filling medium 4 and avoid a large force applied to the third support 23 by the filling medium 4 concentrated in the hole area KA when the length of the third support 23 is equal to the length of the first support 21, in some alternative embodiments, the third support 23 includes at least one opening 231. The opening 231 is used for communicating the side of the third support 23 close to the first support 21 with the side of the third support 23 away from the first support 21. It will be appreciated that the opening 231 divides the third support 23 into at least two portions. Due to the opening 231, the excessive filling medium 4 can enter the space between the third support 23 and the first support 21 through the opening 231, and at the same time, the gas in the hole area KA can be released through the opening 231, so that the generation of bubbles in the hole area KA after the filling medium 4 is disposed is avoided.
In some alternative embodiments, the third support 23 is provided with a plurality of openings 231, and the plurality of openings 231 are equally spaced. This structure contributes to uniform distribution of the colloid and to improvement in flatness of the filling medium 4. Optionally, the third support 23 is provided with four openings 231.
In some alternative embodiments, the third supporting member 23 includes a plurality of supporting blocks 232 spaced around the aperture area KA, and at least two circles of supporting blocks 232 are disposed in a direction from the center of the aperture area KA to the display area AA.
Referring to fig. 7 and 8, two circles of supporting blocks 232 are disposed in a direction from the center of the aperture area KA to the display area AA. Wherein, a plurality of supporting blocks 232 in one circle can be arranged at equal intervals or at unequal intervals. When the supporting blocks 232 are arranged at equal intervals, the colloid is uniformly distributed in the intervals among the supporting blocks 232, and the flatness of the filling medium 4 is improved.
It is understood that a plurality of supporting blocks 232 are dispersed around the aperture area KA, and while the supporting blocks 232 serve to support the cover plate 3 and block part of the filling medium 4, the space between adjacent supporting blocks 232 can be used to accommodate the excess filling medium 4, and each supporting block 232 located in the transition area NA may have the same structure as the second supporting member 22 located in the display area AA, such as a cylinder or a rectangular cylinder. Optionally, the orthographic shape of the supporting block 232 on the substrate 1 is at least one of a polygon and a circle.
Referring to fig. 8, in some alternative embodiments, the density of the supporting blocks 232 decreases gradually from the center of the aperture area KA to the display area AA.
It should be noted that the distribution density of each circle of supporting blocks 232 is gradually decreased, and it can be specifically understood that the smaller the interval between two adjacent supporting blocks 232 in one circle of supporting blocks 232 closer to the aperture area KA, the smaller the amount of the filling medium 4 that can be accommodated by the adjacent supporting blocks 232, and correspondingly, the larger the interval between two adjacent supporting blocks 232 in one circle of supporting blocks 232 farther from the aperture area KA, the larger the amount of the filling medium 4 that can be accommodated by the adjacent supporting blocks 232, and this structure makes the supporting function of the supporting blocks 232 located in the inner circle better, that is, the supporting function of the supporting blocks 232 close to the aperture area KA is better. Meanwhile, the overflowed redundant filling medium 4 enters the space between two adjacent supporting blocks 232 of the outer ring, which helps to ensure the display effect.
