The inventor finds that under the action of gravity and atmospheric pressure, the packaging cover plate is easy to generate deformation similar to a bathtub curve, when light irradiates a screen from the cover plate, the optical path difference of different light beams in a wedge-shaped microcavity formed between the packaging cover plate and the display substrate is different, so that reflected light generated on the lower surface of the packaging cover plate and reflected light generated on the upper surface of the display substrate interfere with each other, and then the problem of Newton rings appears, and the display quality is affected.
A first embodiment of the present invention relates to a display panel, as shown in fig. 1 to 4, including: the display substrate 11, be located the encapsulation apron 12 on the display substrate 11, and set up the support column 13 between display substrate 11 and encapsulation apron 12, encapsulation apron 12 is used for sealed display substrate 11, and support column 13 is used for supporting encapsulation apron 12, and wherein, support column 13 is close to encapsulation apron 12 one side and is provided with the deformation carrier part, and the deformation carrier part includes: the package cover plate 12 is supported by the protrusions 15, the protrusions 15 comprise first protrusions 151 and second protrusions 152, and the first protrusions 151 and the second protrusions 152 are located on two opposite sides of the groove 14 and are adjacent to the groove 14.
Since the support column 13 is provided with a deformation bearing part near the package cover plate 12 side, the deformation bearing part comprises: the groove 14 and the protrusion 15 adjacent to the groove 14, the protrusion 15 is used for bearing the package cover plate 12, the protrusion 15 comprises a first protrusion 151 and a second protrusion 152, the first protrusion 151 and the second protrusion 152 are respectively located at two opposite sides of the groove 14 and are adjacent to the groove 14, under the action of gravity and atmospheric pressure of the package cover plate 12, the heights of the first protrusion 151 and the second protrusion 152 are reduced and are extruded to the periphery, the groove 14 located between the first protrusion 151 and the second protrusion 152 bulges under the extrusion action of the two sides, so that the heights of the first protrusion 151, the second protrusion 152 and the groove 14 tend to be consistent (the deformation bearing part is close to the package cover plate 12 and is close to the flat), the contact area of the deformation bearing part and the package cover plate 12 is increased, the supporting capacity of the supporting column 13 is improved, the situation of concave deformation of the package cover plate 12 is weakened, newton ring phenomena are improved, and the display quality of the display panel is improved.
The following describes the specific shape and arrangement of the deformed carrying portion, and the following is merely provided for easy understanding, and is not necessary to implement the present embodiment.
In this embodiment, the support column 13 includes a top surface near one side of the package cover 12, the top surface includes a central area, and an edge area surrounding the central area, and the number of deformation carriers may be one, and one deformation carrier is located in the central area. Since the top surface is generally convex, the first protrusion 151 and the second protrusion 152 are more easily abutted against the package cover 12 when the deformation bearing part is disposed in the central area (i.e., the highest position of the support column), so that the heights of the first protrusion 151, the second protrusion 152 and the groove 14 are more easily consistent, and the contact area between the deformation bearing part and the package cover 12 is increased.
It can be understood that the number of the deformation bearing parts can be multiple, and multiple deformation bearing parts are axisymmetric or centrosymmetric, so that the support force provided by the deformation bearing parts is more uniform, and the support columns 13 can support the package cover plate 12 more stably.
In this embodiment, the groove 14 may be annular, the groove 14 is disposed around the first protrusion 151, the second protrusion 152 is disposed around the groove 14, the inner edge of the groove 14 is connected with the edge of the first protrusion 151, and the outer edge of the groove 14 is connected with the edge of the second protrusion 152. So set up, the second protruding 152 can extrude the outward flange of annular recess 14 from the outside, and first protruding 151 can inboard extrusion annular recess 14's inward flange, annular recess 14 receives the extrusion force of inside and outside both sides, more does benefit to the uplift of recess 14.
Specifically, the first protrusion 151 may be a protrusion, and the second protrusion 152 may be disposed in the following ways:
the first arrangement is that the second protrusion 152 may be annular, and the annular second protrusion 152 is disposed around the first protrusion 151. In this arrangement, the annular second protrusion 152 can squeeze the support column 13 from all directions outside the annular groove 14, which is beneficial to all parts of the annular groove 14 to bulge, and increases the contact area between the support column 13 and the package cover plate 12.
The second setting mode is, the quantity of second protruding 152 can be two, and two second protruding 152 are located the both sides that first protruding 151 is relative respectively, so set up, can be better with rectangular support column 13 adaptation, through arranging first protruding 151 and the second protruding 152 that is located first protruding 151 both sides in the long limit direction of rectangular support column 13, increased the support column 13 and encapsulation apron 12's contact point, improved the stability of support.
The third arrangement manner is that the number of the second protrusions 152 may be plural, the plural second protrusions 152 are spaced apart from each other and are disposed around the first protrusions 151, alternatively, the distances between the plural second protrusions 152 and the first protrusions 151 may be equal, the plural second protrusions 152 are disposed along the annular shape at equal intervals to bear the package cover 12, and the plural second protrusions 152 uniformly provide supporting force, so that the package cover 12 can be supported more stably.
Of course, the recess 14 may not be annular, for example, the recess 14 may include one, two or more recesses, wherein the two recesses may be symmetrical about the first protrusion 151 and the plurality of recesses may be equally spaced around the first protrusion 151.
In this embodiment, as shown in fig. 2, in the direction perpendicular to the display substrate 11, the height of the second protrusion 152 is greater than the height of the first protrusion 151, in other words, the height of the second protrusion 152 away from the top of the display substrate 11 is greater than the height of the first protrusion 151 away from the top of the display substrate 11, or in other words, the distance between the top of the second protrusion 152 and the display substrate 11 is greater than the distance between the top of the first protrusion 151 and the display substrate 11, since the span of the supporting points of the second protrusion 152 is greater (the second protrusion 152 is disposed around the first protrusion 151, "the distance" between the supporting points on opposite sides of the second protrusion 152 is greater than "the distance" between the two farthest contacting points on the first protrusion 151 "), by providing the height of the second protrusion 152 to be greater than the height of the first protrusion 151, the second protrusion 152 having a greater supporting point span can be preferentially ensured to be in contact with the package cover 12, and the supporting stability is improved.
It will be appreciated that, as shown in fig. 3, the height of the second protrusion 152 may be smaller than that of the first protrusion 151 in a direction perpendicular to the display substrate 11, and for process reasons, the top surface of the support column 13 is generally convex, so that the preparation process of setting the height of the second protrusion 152 smaller than that of the first protrusion 151 is simpler and has a cost advantage.
Of course, the height of the second protrusion 152 may be equal to the height of the first protrusion 151 in the direction perpendicular to the display substrate 11, and at this time, the length of the first protrusion 151 is smaller than that of the second protrusion 152 in the direction perpendicular to the display substrate 11, and since the length of the first protrusion 151 at the center is smaller, the length of the second protrusion 152 at the periphery is smaller, so that the height difference caused by the convex surface of the top surface of the support column 13 can be compensated, which is beneficial to uniform stress of the first protrusion 151 and the second protrusion 152.
In practical application, when the support column is formed, different exposure amounts or etching amounts can be implemented on different areas according to the shape requirement, specifically, the preparation of the grooves 14 and the protrusions 15 can be realized by a differential process that the etching amount (or exposure amount) of the areas where the grooves 14 are located is larger than the etching amount (or exposure amount) of the areas where the protrusions 15 are located.
As shown in fig. 4, in some embodiments, the groove 14 may include an annular first groove 141 and an annular second groove 142, the protrusion 15 further including a third protrusion 153 disposed around the second protrusion 152, the first groove 141 disposed around the first protrusion 151, the second protrusion 152 disposed around the first groove 141, the second groove 142 disposed around the second protrusion 152, and the third protrusion 153 disposed around the second groove 142. Specifically, the inner edge of the first groove 141 is connected to the edge of the first protrusion 151, the outer edge of the first groove 141 is connected to the edge of the second protrusion 152, the inner edge of the second groove 142 is connected to the edge of the second protrusion 152, and the outer edge of the second groove 142 is connected to the edge of the third protrusion 143. That is, the deformation carrier includes the convex blocks located in the middle, and the plurality of annular grooves and the plurality of annular protrusions alternately arranged, so that the contact points of the deformation carrier and the encapsulation cover 12 are distributed more uniformly, thereby improving the stability of the support.
Alternatively, in a direction perpendicular to the display substrate 11, the height of the third protrusion 153 may be greater than the height of the second protrusion 152, the height of the second protrusion 152 may be greater than the height of the first protrusion 151, and since the span of the supporting points of the third protrusion 153 is greater ("the distance of the supporting points on opposite sides of the third protrusion 153 is" greater than "the distance of the supporting points on opposite sides of the second protrusion 152"), by providing the height of the third protrusion 153 may be greater than the height of the second protrusion 152, it can be preferentially ensured that the third protrusion 153 of a greater supporting point span can be in contact with the package cover plate 12, improving the stability of the support.
The constituent materials of the support posts 13 may include a photosensitive siloxane (PSPD 0) or a photosensitive polyimide photoresist (PSPI), among others. In some embodiments, at least a portion of the support posts 13 are doped with at least one of a rigid strip or a rigid particle, optionally, the rigid strip is made of at least one of silicon, titanium, steel, and a fiber-reinforced composite, and the rigid particle is made of at least one of silicon, titanium, steel, and a fiber-reinforced composite, so as to increase the rigidity of the support posts 13 and prevent the support posts 13 from deforming or breaking.
In practical application, the number of the support columns 13 is multiple, the support columns 13 are arranged in the display area of the display substrate 11 at intervals, the display substrate 11 further comprises a non-display area arranged around the display area, the non-display area is provided with a Frit layer for sealing between the display substrate 11 and the packaging cover plate 12, and all or part of the support columns 13 can be provided with the grooves 14 and the protrusions 15.
Compared with the prior art, when the packaging cover plate 12 presses the bulge 15 under the action of gravity and atmospheric pressure, the bulge 15 is pressed down under the pressure of the packaging cover plate 12, and the top of the support column 13 is pressed to enable the groove 14 adjacent to the bulge 15 to bulge, so that the contact area between the support column 13 and the packaging cover plate 12 is increased, the supporting capacity of the support column 13 is improved, the situation of concave deformation of the packaging cover plate 12 is weakened, newton ring phenomenon is improved, and the display quality of the display panel is improved.
