Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the following will explain in detail each embodiment of the present invention with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that in various embodiments of the invention, numerous technical details are set forth in order to provide a better understanding of the invention. However, the technical solution claimed in the present invention can be realized without these technical details and various changes and modifications based on the following embodiments.
The first embodiment of the present invention relates to a display panel 100, which has a specific structure as shown in fig. 1, including:
the substrate 1, the barricade 3 set on the substrate 1, the projection pattern of the outer wall 301 or the inner wall 302 of the barricade 3 on the substrate 1 is curve shape.
It should be noted that, as shown in fig. 2, the display panel 100 includes the display area 101 and the non-display area 102, the inner wall 302 of the retaining wall 3 is a side wall close to the display area 101, the outer wall 301 is a side wall far from the display area 101, the projection pattern of the outer wall 301 of the retaining wall 3 on the substrate 1 is a curved shape, and the projection pattern of the inner wall 302 on the substrate 1 is a linear shape, it can be understood that the retaining wall 3 further includes a bottom surface 303 adjacent to the substrate 1 and a top surface 304 disposed opposite to the bottom surface 303, and when the projection pattern of the outer wall 301 of the retaining wall 3 on the substrate 1 is a curved shape, both sides of the bottom surface 303 and the top surface 304 close to the outer.
As shown in fig. 3, the projection pattern of the outer wall 301 of the retaining wall 3 on the base plate 1 is a straight line shape, the projection pattern of the inner wall 302 on the base plate 1 is a curved line shape, and the sides of the bottom surface 303 and the top surface 304 close to the inner wall 302 are both curved sides.

It can be understood that the OLED device of the display panel 100 needs to inject electrons from the cathode during operation, and the lower the work function of the cathode is, the better the work function of the cathode is, but the cathode is usually made of metal materials such as aluminum, magnesium, calcium, silver, etc., and the chemical properties of the cathode are relatively active and are very reactive to moisture and oxygen penetrating into the cathode. In addition, moisture and oxygen can chemically react with the hole transport layer and the electron transport layer of the OLED device, which can cause the OLED device to fail. Therefore, the OLED device is effectively encapsulated, and each functional layer of the OLED device is sufficiently separated from components such as water vapor and oxygen in the atmosphere, so that the service life of the OLED device can be greatly prolonged, and the service life of the display panel 100 is prolonged.
Compared with the prior art, the embodiment of the utility model has the advantages that the retaining wall 3 is arranged on the substrate 1, so that the water vapor in the air can be prevented from entering the display panel 100 along the direction Y perpendicular to the thickness direction X of the display panel, and the devices in the display panel 100 are further protected from being corroded by the water vapor; in addition, because when the display panel 100 is bent, the retaining wall 3 can receive a large bending stress, and is very easy to break, the projection pattern on the substrate 1 through the outer wall 301 or the inner wall 302 of the retaining wall 3 is a curved shape, and compared with the retaining wall 3 in which the projection pattern on the substrate 1 is a straight line shape in the prior art, the retaining wall shape provided by the embodiment can play a role in dispersing stress when the display panel 100 is bent, so that the retaining wall 3 is prevented from being damaged when the display panel 100 is bent, and the retaining wall 3 can play a role in isolating components such as water vapor and oxygen in the air, thereby improving the packaging performance of the display panel 100.
The following describes the implementation details of the display panel 100 of the present embodiment in detail, and the following is only provided for the convenience of understanding and is not necessary for implementing the present embodiment.
In the present embodiment, the substrate 1 may be a glass substrate, CPI (transparent polyimide), PI (polyimide), PET (high temperature polyester), PEN (polyethylene naphthalate), or the like, and the material of the substrate 1 is not particularly limited in the present embodiment, and different materials may be selected according to actual requirements to manufacture the substrate 1. In addition, the retaining wall 3 may be made of CPI (transparent polyimide), PI (polyimide), PET (high temperature polyester), PEN (polyethylene naphthalate), polycarbonate, polyethersulfone, polyethylene terephthalate, polyarylate, glass fiber reinforced plastic, or the like, and the retaining wall 3 may be made of different materials according to actual requirements without specifically limiting the material of the retaining wall 3. The retaining wall 3 is made of inorganic materials, so that the retaining wall 3 has good quality and tightness, and the packaging effect of the display panel 100 is further improved.
As shown in fig. 4, the display panel 100 includes a display region 101 and a non-display region 102, the dam 3 is disposed in the non-display region 102, and the display panel 100 further includes an encapsulation layer 2, wherein the encapsulation layer 2 covers the display region 101 and partially covers the dam 3. Through the arrangement of the structure, the retaining wall 3 located in the non-display area 102 can block water vapor and oxygen from entering the display area 101, and the packaging effect of the display panel 100 is further ensured. It is to be understood that the non-display area 102 shown in fig. 4 is disposed around the display area 101, in practical applications, the non-display area 102 may also be disposed side by side with the display area 101, and the non-display area 102 may also partially surround the display area 101, and the embodiment does not specifically limit the relative position relationship between the display area 101 and the non-display area 102.
It should be noted that, because TFE (thin film encapsulation) encapsulation has a better water-blocking and oxygen-blocking effect and can correspond to flexible encapsulation, in this embodiment, the encapsulation layer 2 includes a first inorganic encapsulation layer 21 adjacent to the substrate 1 and an organic encapsulation layer 22 disposed on a side of the first inorganic encapsulation layer 21 away from the substrate 1, the first inorganic encapsulation layer 21 covers the display region 101 and extends to the covering wall 3, and the organic encapsulation layer 22 covers the first inorganic encapsulation layer 21 in the display region 101. Further, the encapsulation layer 2 further includes a second inorganic encapsulation layer 23, and the second inorganic encapsulation layer 23 covers the organic encapsulation layer 22 and the first inorganic encapsulation layer 21 not covered by the organic encapsulation layer 22. That is, in the display area 101, the second inorganic encapsulating layer 23 is directly disposed on the organic encapsulating layer 22, and in the non-display area 102 outside the display area 101, since there is no organic encapsulating layer 22, the second inorganic encapsulating layer 23 is directly disposed on the first inorganic encapsulating layer 21, so that the second inorganic encapsulating layer 23, the organic encapsulating layer 22 and the first inorganic encapsulating layer 21 collectively realize the encapsulation of the display panel 100. Since the inorganic encapsulation layer has good sealing performance but high hardness, and the organic encapsulation layer has low hardness but is permeable to water vapor, the encapsulation layer 2 having an inorganic-organic-inorganic laminated structure can ensure the encapsulation performance of the display panel 100 without affecting the bending capability of the display panel 100.
As shown in fig. 5, in another possible embodiment, the encapsulation layer 2 includes a first inorganic encapsulation layer 21, an organic encapsulation layer 22 and a second inorganic encapsulation layer 23, the first inorganic encapsulation layer 21 covers the display region 101 and extends to cover the region of the dam 3 adjacent to the display region 101, the organic encapsulation layer 22 covers the first inorganic encapsulation layer 21, and the second inorganic encapsulation layer 23 covers the organic encapsulation layer 22. It should be noted that, with such a configuration, the bending capability of the display panel 100 is not affected while the packaging performance of the display panel 100 is ensured.
Specifically, the material of the first inorganic encapsulation layer 21 and the second inorganic encapsulation layer 23 is preferably silicon oxide, the material of the organic encapsulation layer 22 is preferably acrylic, the encapsulated inorganic silicon oxide layer can be manufactured by adopting a film coating method such as CVD (chemical vapor deposition) or sputtering, the acrylic layer can be manufactured by adopting a method such as ink-jet printing, and the encapsulation layer 2 plays a role in isolating water and oxygen, can effectively prevent air from contacting with the display device layer, and does not affect the optical characteristics of the screen body. Note that the thickness of the encapsulating layer 2 is in the range of 8 to 10 μm. The packaging layer 2 with the thickness range can isolate water and oxygen, prevent the display device layer from being corroded, enable the thickness of the display panel 100 to be within a reasonable range, and avoid the influence of the excessive thickness of the display panel 100 on the bending performance of the display panel 100. It is understood that, since the organic encapsulation layer 22 is in a liquid state before being cured in the TFE encapsulation process, the organic encapsulation layer has high fluidity, and it is difficult to precisely control the diffusion thereof, so that it is easy to flow out, resulting in poor encapsulation effect of the display panel 100. Therefore, by disposing the organic encapsulation layer 22 in the display region 101, the retaining wall 3 is disposed in the non-display region 102 at the periphery of the display region 101, so that the retaining wall 3 can also function to prevent the organic encapsulation layer 22 from overflowing, thereby ensuring the encapsulation effect of the display panel 100.
It is worth mentioning that when the display panel 100 is applied to a flexible OLED display device or a curved OLED display device, a large bending stress exists between the retaining wall 3 and the first inorganic encapsulation layer 21 at the bending portion, which is very easy to cause layer fracture or peeling, so that moisture and oxygen enter the OLED device along the gap, causing the OLED device to fail. Therefore, by setting the projection pattern of the outer wall 301 or the inner wall 302 of the retaining wall 3 on the substrate 1 to be a curved shape, that is, at least one side surface of the retaining wall 3 is a curved surface, the effect of dispersing stress can be achieved when the display panel 100 is bent, so that the retaining wall 3 is prevented from being peeled off from the first inorganic encapsulating layer 21, and the encapsulating effect of the display panel 100 is further improved.
Preferably, the retaining wall 3 includes a first retaining wall 31 and a second retaining wall 32, the second retaining wall 32 is disposed on a side of the first retaining wall 31 away from the display area 101, and the height of the second retaining wall 32 is greater than the height of the first retaining wall 31. That is, the second retaining wall 32 is closer to the edge of the display panel 100 than the first retaining wall 31, and the height of the second retaining wall 32 is greater than the height of the first retaining wall 31, so that even if the organic encapsulating layer 22 flows out from the first retaining wall 31, the organic encapsulating layer is blocked by the second retaining wall 32, thereby further ensuring the encapsulating effect of the display panel 100. Specifically, the height range of the first retaining wall 31 is 3 micrometers to 5 micrometers, and the first retaining wall 31 with the height range can isolate water and oxygen, prevent the display device layer from being corroded, enable the thickness of the display panel 100 to be within a reasonable range, and avoid the influence on the bending performance of the display panel 100 due to the excessively thick thickness; the height of the second wall 32 is in a range from 5 micrometers to 8 micrometers, and the height of the second wall 32 in this height range can be greater than that of the first wall 31, so that the organic encapsulation layer 22 that may flow out from the first wall 31 is blocked, and at the same time, the thickness of the display panel 100 is in a reasonable range, and the influence of the excessive thickness on the bending performance of the display panel 100 is avoided.
Preferably, since the bending stress of the central region of the display panel is larger and the bending stress of the edge region is smaller during the bending process of the display panel 100, and the first retaining wall 31 is closer to the central region of the display panel 100 than the second retaining wall 32, the bending stress of the second retaining wall 32 is smaller than the bending stress of the first retaining wall 31 during the bending process of the display panel 100, in this embodiment, the curvature radius of the side wall of the second retaining wall 32 may be set to be larger than the curvature radius of the side wall of the first retaining wall 31, that is, the curvature degree of the second retaining wall 32 is smaller than the curvature degree of the first retaining wall 31, and the packaging effect of the display panel 100 can also be ensured.
For ease of understanding, several achievable shapes of the retaining wall 3 in this embodiment are specifically exemplified below:
as shown in fig. 4, taking the display area 101 and the non-display area 102 as rectangular areas as an example, the retaining wall 3 is disposed in the non-display area 102 and surrounds the display area 101. The top surface 302 and the bottom surface (not shown) of the retaining wall 3 are both curved. Specifically, the retaining wall 3 is formed by connecting a plurality of circular arcs with the same radian, the radian of the circular arcs is preferably 50-60 degrees, and the circular arcs with the angle range can enable the retaining wall 3 to have better bending resistance.
As shown in fig. 6, taking the display area 101 and the non-display area 102 as rectangular areas as an example, the retaining wall 3 is disposed in the non-display area 102 and surrounds the display area 101. The top surface 302 and the bottom surface (not shown) of the retaining wall 3 are both gourd-shaped. Specifically, the retaining wall 3 is formed by connecting a plurality of "gourds" with the same shape, each "gourds" comprises a body part 311 and a gourds part 312 connected with the body part 311, the ratio of the maximum width of the body part 311 to the maximum width of the gourds part 312 is between 3:1 and 4:1, and the ratio range of the "gourds" enables the retaining wall 3 to have better bending resistance.
As shown in fig. 7, taking the display area 101 and the non-display area 102 as rectangular areas as an example, the retaining wall 3 is disposed in the non-display area 102 and surrounds the display area 101. The top surface 302 and the bottom surface (not shown) of the retaining wall 3 are both circular in shape. Specifically, the retaining wall 3 is formed by connecting a plurality of circular rings with the same shape, the diameter range of the circular rings is 3 microns to 5 microns, the diameter of the hollow circle is more than 5 microns, and the circular rings with the diameter range can enable the retaining wall 3 to have better bending resistance.
It is to be understood that the shape of the display area 101 and the non-display area 102 is not particularly limited in this embodiment, and may be other shapes such as a circle and a semicircle; the shape of the retaining wall 3 is not specifically limited, and only the projection patterns of the outer wall 301 and the inner wall 302 of the retaining wall 3 on the substrate 1 need to be ensured to be curve shapes; in addition, taking the display area 101 and the non-display area 102 as an example of a rectangular area, the shape of the retaining wall 3 on each side of the non-display area 102 does not need to be the same, in other words, the rectangular non-display area 102 is composed of four sides, and if the projected pattern of the retaining wall 3 on the substrate 1 is gourd-shaped on the first side of the rectangular area, the projected pattern of the retaining wall 3 on the substrate 1 may be circular or curved on the second side of the rectangular area.
The second embodiment of the present invention relates to a display panel 200, and the second embodiment is further improved on the basis of the first embodiment, and the specific improvements lie in: in the second embodiment, as shown in fig. 8, the display panel 200 further includes an adhesive layer 4 covering at least the retaining wall 3.
When the display panel 200 is applied to a flexible OLED display device or a curved OLED display device, a large bending stress exists between the retaining wall 3 and the encapsulation layer 2 at a bending position, and layer fracture or peeling is easily generated, so that water vapor and oxygen enter the OLED device along a gap, and the OLED device fails. Therefore, the display panel 200 further includes an adhesive layer 4 covering at least the retaining wall 3. Through the arrangement of the structure, the packaging layer 2 and the retaining wall 3 are bonded together by the glue with strong viscosity, so that the packaging layer 2 is effectively prevented from being separated from the retaining wall 3 when the display panel 200 is bent, water vapor and oxygen enter the OLED device along the gap, and the bending capacity and the packaging performance of the display panel 200 are further improved. Specifically, the adhesive layer 4 is made of a pressure-sensitive adhesive, which is a pressure-sensitive adhesive, and the peeling force of the general pressure-sensitive adhesive (the peeling force exhibited after the adhesive tape is pressed and adhered to an adhered surface) < the cohesive force of the adhesive (the acting force between the pressure-sensitive adhesive molecules) < the cohesive force of the adhesive (the adhesive force between the adhesive and the base material), so that the pressure-sensitive adhesive does not come unstuck during use. Preferably, the material of the adhesive layer 4 in this embodiment is OCA optical cement or OCR adhesive, and both the OCA optical cement and the OCR adhesive have strong viscosity. It should be understood that the material of the adhesive layer 4 is not limited in this embodiment, and other adhesives capable of adhering the retaining wall 3 and the encapsulating layer 2 are within the scope of the present embodiment. In addition, the adhesive layer 4 in this embodiment is a patterned adhesive layer, and preferably, the shape of the patterned adhesive layer 4 is the same as that of the retaining wall 3. In this way, the production cost of the display panel 200 can be reduced while the retaining wall 3 and the encapsulating layer 2 are firmly bonded.

Through seting up recess 30 on barricade 3, when display panel 300 buckles, barricade 3 will receive the external force of buckling, and recess 30 will take place deformation this moment to the external force of buckling that receives barricade 3 shifts, also can release the stress that barricade 3 self received simultaneously, thereby has avoided display panel 300 to buckle in-process barricade 3 and has taken place the fracture, has improved display panel 300's encapsulation effect.
Specifically, the number of the grooves 30 in this embodiment may be multiple, so as to further prevent the retaining wall 3 from breaking during the bending process of the display panel 300; the groove depth of the groove is between 1 micron and 2 microns, and the groove 30 with such a groove depth can ensure that water vapor and oxygen in the air can not enter the display panel while ensuring that the external bending force and stress on the retaining wall 3 are released.
Those skilled in the art can appreciate that the present embodiment can achieve the same technical effects as the foregoing embodiment, and therefore, the details are not repeated herein to avoid repetition.
