All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application. Furthermore, it should be understood that the detailed description and specific examples, while indicating exemplary embodiments of the invention, are given by way of illustration and explanation only, and are not intended to limit the scope of the invention. In the present application, unless indicated to the contrary, the use of the directional terms "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, and more particularly to the orientation of the figures of the drawings; while "inner" and "outer" are with respect to the outline of the device.
The embodiment of the application provides a display panel and a manufacturing method thereof. The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.
Referring to fig. 1 and fig. 2, fig. 1 is a first structural schematic diagram of a first implementation manner of a display panel provided in an embodiment of the present application, and fig. 2 is a second structural schematic diagram of the first implementation manner of the display panel provided in the embodiment of the present application. As shown in fig. 1 and fig. 2, the display panel 10 provided in the embodiment of the present application includes a display area 10a and a non-display area 10b, where the non-display area 10b is located on one side of the display area 10 a. The non-display area 10b is provided with an R angle.
Fig. 2 is a schematic view of a cross-sectional structure of the display panel shown in fig. 1, taken along a line a-a. In the embodiment of the present application, the non-display area 10b is disposed on the peripheral side of the display area 10a, i.e., the non-display area 10b is disposed around the display area 10 a. Of course, the non-display area 10b may be disposed on only one side of the display area 10a according to the selection of the actual situation and the specific requirement, and is not limited herein. The R corner is a rounded corner of an arc tangent to two intersecting straight lines, specifically, in the implementation of the present application, the R corner is a rounded corner of an arc tangent to a long side of the display panel 10 and a short side of the display panel.
The display panel 10 includes a first substrate 101, a gate trace 102, and a stress release layer 103. The gate trace 102 is disposed on the first substrate 101. Specifically, the gate trace 102 is disposed on a surface of the first substrate 101 close to the stress release layer 103. The stress release layer 103 is disposed on a surface of the gate trace 102 away from the first substrate 101.
The gate trace 102 includes a first portion 102a and a second portion 102b extending along different directions, the first portion 101a and the second portion 102b are connected at an R corner, and an orthogonal projection of the first portion 101a and the second portion 102b on the first substrate 101 is located in an orthogonal projection of the stress release layer 103 on the first substrate 101.
It should be noted that, when the display panel 10 is bent, the gate trace 102 is mainly broken at the connection between the two portions. In the embodiment of the present application, the stress relief layer 103 is disposed directly above the connection of the first portion 102a and the second portion 102b of the gate trace 102. Therefore, the position of the neutral plane of the display panel 10 can be changed, the layer where the gate trace 102 is located is prevented from being the layer with the most serious stress concentration phenomenon, and the stress can be dispersed or absorbed. Therefore, the gate trace 102 is prevented from being broken at the connection between the first portion 102a and the second portion 102b due to stress concentration, and the cross striation of the display panel 10 during displaying can be avoided, thereby improving the yield of the display panel 10.
It should be noted that, in the embodiment of the present application, the material of the stress release layer 103 is an oxidative dehydrogenation, and of course, other organic photoresist materials or inorganic materials may be used for the stress release layer 103 as long as they satisfy the effect of dispersing or absorbing stress.
Referring to fig. 3, fig. 3 is a schematic structural diagram of a display panel according to a second implementation manner of the present application. As shown in fig. 3, the display panel 10 shown in fig. 3 is different from the display panel shown in fig. 2 in that: the display panel 10 further includes a pixel defining layer 104 and a pixel layer 105, the pixel defining layer 104 and the stress releasing layer 103 are disposed on the same layer, the pixel defining layer 104 is provided with a plurality of first grooves 104a, the pixel layer 105 fills the first grooves 104a, and a distance L1 between a side of the stress releasing layer 103 close to the pixel defining layer 104 and a side of the pixel defining layer 104 close to the stress releasing layer 103 is greater than 45 μm.
It should be noted that, in the display panel 10 provided in the embodiment of the present application, the stress relief layer 103 is disposed and extends inward as much as possible, so as to prevent the gate trace 102 from being broken at the connection between the first portion 102a and the second portion 102b due to stress concentration. But the pixel defining layer 104 is used to isolate the pixel layers 105 of different colors. Therefore, the pixel definition layer 104 must have a certain thickness to ensure the normal display of the display panel 10. Therefore, in the embodiment of the present application, it is necessary to limit the inward extending length of the stress release layer 103, that is, the distance from the stress release layer 103 to the pixel definition layer 104, so as to enable the pixel definition layer 104 to have a thickness for ensuring normal display of the display panel 10.
Specifically, in the embodiment of the present application, the distance L1 between the side of the stress release layer 103 close to the pixel defining layer 104 and the side of the pixel defining layer 104 close to the stress release layer 103 is 46 micrometers, 50 micrometers, 55 micrometers, or 60 micrometers. The specific distance L1 between the side of the stress release layer 103 close to the pixel defining layer 104 and the side of the pixel defining layer 104 close to the stress release layer 103 is determined by the specific requirements of the display panel 10.
In the embodiment of the present invention, the distance L1 between the side of the stress releasing layer 103 close to the pixel defining layer 104 and the side of the pixel defining layer 104 close to the stress releasing layer 103 only needs to be increased as much as possible on the basis of satisfying the function of the stress releasing layer 103 of preventing the gate trace 102 from being broken at the connection between the first portion 102a and the second portion 102b due to stress concentration.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a third implementation manner of the display panel according to the embodiment of the present disclosure. As shown in fig. 4, the display panel 10 shown in fig. 4 is different from the display panel shown in fig. 3 in that: the display panel 10 further includes a first insulating layer 106. The first insulating layer 106 is disposed between the gate trace 102 and the stress relief layer 103. And a plurality of concave parts 103a are arranged on one surface of the stress release layer 103 close to the first insulating layer 106, and the first insulating layer 106 fills the concave parts 103 a.
It should be noted that, since the gate trace 102 needs to have conductivity, an insulating layer needs to be disposed between the gate trace 102 and other film layers to prevent the other film layers from affecting the signal transmission of the gate trace 102. Therefore, in the embodiment of the present application, the first insulating layer 106 is disposed between the gate trace 102 and the stress relief layer 103 to prevent the gate trace 102 from contacting other film layers to affect signal transmission. Of course, since the stress release layer 103 is also generally made of an insulating material, the first insulating layer 106 may not be provided.
It should be noted that, by providing the plurality of recessed portions 103a on the surface of the stress releasing layer 103 close to the first insulating layer 106, the contact area between the stress releasing layer 103 and other film layers can be further increased, which is more beneficial to releasing stress, so as to better achieve the effect of absorbing stress or buffering stress, and further better avoid the gate trace 102 from breaking at the joint of the first portion 102a and the second portion 102b due to stress concentration, so as to avoid the cross-striation phenomenon occurring in the display of the display panel 10, and improve the yield of the display panel 10.
Specifically, the cross-sectional shape of the recessed portion 103a is rectangular, but of course, the cross-sectional shape of the recessed portion 103a may be other shapes according to the selection of the actual situation and the specific requirement, for example, the cross-sectional shape of the recessed portion 103a may be oval, circular, or trapezoidal, and is not limited herein.
Specifically, the connection point of the first portion 102a and the second portion 102b of the gate trace 102 is located on a side of the stress releasing layer 103 close to the pixel defining layer 104. Therefore, the width of the recess 103a may gradually increase along the direction from the pixel defining layer 104 to the stress releasing layer. The effect of avoiding the gate trace 102 from being broken at the connection between the first portion 102a and the second portion 102b due to stress concentration can be achieved.
Specifically, the pitch L2 of the recesses 103a increases in order along the direction from the pixel defining layer 104 to the stress relieving layer 103. It should be noted that the connection between the first portion 102a and the second portion 102b of the gate trace 102 is located on a side of the stress releasing layer 103 close to the pixel defining layer 104. Therefore, the distance L2 between the recesses 103a increases in sequence along the direction from the pixel defining layer 104 to the stress releasing layer 103, so as to achieve the effect of better preventing the gate trace 102 from being broken at the connection between the first portion 102a and the second portion 102b due to stress concentration.
Referring to fig. 5, fig. 5 is a schematic structural diagram of a fourth implementation manner of the display panel according to the embodiment of the present application. As shown in fig. 5, the display panel 10 shown in fig. 5 is different from the display panel shown in fig. 4 in that: the intervals L2 of the recesses 103a are equal.
It should be noted that, by defining the equal intervals L2 of the concave portions 103a, the difficulty of the manufacturing process of the display panel 10 can be reduced, which is helpful for reducing the manufacturing cost of the display panel 10.
Referring to fig. 6, fig. 6 is a schematic structural diagram of a display panel according to a fifth implementation manner of the embodiment of the present application. The display panel 10 shown in fig. 6 differs from the display panel shown in fig. 3 in that: the stress release layer 103 includes a first stress release sublayer 1031, a second stress release sublayer 1032, and a third stress release sublayer 1033, which are sequentially stacked, and the first stress release sublayer 1031, the second stress release sublayer 1032, and the third stress release sublayer 1033 have different elastic moduli.
It should be noted that, in the embodiment of the present application, by providing multiple stress release sublayers with different elastic moduli, stress can be sequentially dispersed and absorbed, and an effect of preventing the gate trace 102 from being broken at a connection portion of the first portion 102a and the second portion 102b due to stress concentration can be better achieved.
Specifically, the first stress relieving sublayer 1031 has a lower elastic modulus than the second stress relieving sublayer 1032, and the third stress relieving sublayer 1033 has a lower elastic modulus than the second stress relieving sublayer 1032.
It should be noted that when the gate trace 102 is bent, the stress applied to the gate trace 102 is absorbed by the first stress releasing sublayer 1031, then released by the second stress releasing sublayer 1032, and finally absorbed by the third stress releasing sublayer 1033, so as to ensure that the external stress is not hit on the gate trace 102, thereby achieving the effect of preventing the gate trace 102 from being broken at the connection between the first portion 102a and the second portion 102b due to stress concentration. In addition, by providing the plurality of stress release sub-layers, the display panel 10 can move up the whole stress point in the R-angle region, that is, the display panel 10 moves up the neutral plane in the R-angle region, so that the display panel 10 does not fall on the gate trace 102, thereby further achieving the effect of preventing the gate trace 102 from being broken at the connection between the first portion 102a and the second portion 102b due to stress concentration.
It should be noted that, since the first stress relief sublayer 1031 is smaller than the elastic modulus of the second stress relief sublayer 1032, and the elastic modulus of the third stress relief sublayer 1033 is smaller than the elastic modulus of the second stress relief sublayer 1032. Therefore, the first and third stress relaxation sublayers 1031 and 1033 are generally made of organic materials, and the second stress relaxation sublayer 1032 is made of inorganic materials. Since the flexibility of the organic material is greater than that of the inorganic material, the thickness of the second stress release sublayer 1032 can be made smaller than the thicknesses of the first stress release sublayer 1031 and the third stress release sublayer 1033, so as to further improve the bending capability of the display panel 10, and better achieve the effect of preventing the gate wire 102 from being broken at the connection between the first portion 102a and the second portion 102b due to stress concentration.
It should be noted that, certainly, the stress release layer 103 may further include four, five, or more than five stress release sublayers, so as to better achieve the effect of preventing the gate trace 102 from being broken at the connection between the first portion 102a and the second portion 102b due to stress concentration.
Referring to fig. 7, fig. 7 is a schematic structural diagram of a display panel according to a sixth implementation manner of the present application. The display panel 10 shown in fig. 7 differs from the display panel shown in fig. 6 in that: a second groove 1031a is formed in a surface of the first stress release sublayer 1031 close to the second stress release sublayer 1032, the second stress release sublayer 1032 fills the second groove 1031a, a third groove 1033a is formed in a surface of the third stress release sublayer 1033 close to the second stress release sublayer 1032, and the second stress release sublayer 1032 fills the third groove 1033 a.
It should be noted that, in this embodiment of the application, by providing the second recess 1031a, the contact area between the first stress release sublayer 1031 and the second stress release sublayer 1032 can be increased, thereby being more beneficial to the release of stress, and further being capable of better achieving the effect of absorbing stress or buffering stress, and further being capable of better avoiding the gate trace 102 from being broken at the connection between the first portion 102a and the second portion 102b due to stress concentration, avoiding the cross-striation phenomenon occurring when the display panel 10 displays, and improving the yield of the display panel 10.
It should be noted that, in the embodiment of the present application, by providing the third groove 1033a, a contact area between the third stress releasing sublayer 1033 and the second stress releasing sublayer 1032 can be further increased, thereby facilitating the release of stress, and further achieving an effect of absorbing stress or buffering stress, further better preventing the gate trace 102 from being broken at a connection between the first portion 102a and the second portion 102b due to stress concentration, preventing the display panel 10 from generating a cross-grain phenomenon during displaying, and improving the yield of the display panel 10.
