Description

Technical Field

[0001] This application belongs to the field of display panel technology, specifically relating to display panels and their assembly methods, and electronic devices. Background Technology

[0002] In existing display technologies, the color filter substrate and the array substrate are precisely aligned and bonded using markers on these two substrates. However, the markers have a relatively large light-transmitting area after bonding. When the display panel has a narrow bezel or no bezel, multiple markers can easily cause light leakage, resulting in light leakage in the display panel. Summary of the Invention

[0003] A first aspect of this application provides a display panel, the display panel comprising an array substrate and a color filter substrate stacked together, wherein one of the array substrate and the color filter substrate is provided with a first identifier, and the other is provided with a second identifier.

[0004] The first sign includes a first dimming part and a first sign part surrounding the periphery of the first dimming part; the second sign includes a second sign part and a second dimming part surrounding the periphery of the second sign part; the orthographic projection of the first sign part onto the second sign is located within the second dimming part; the orthographic projection of the second sign part onto the first sign is located within the first dimming part.

[0005] The first marking part and the second marking part are capable of blocking light. At least one of the first dimming part and the second dimming part is made of a color-changing material. The color-changing material can allow light to pass through under a first preset condition and can block light under a second preset condition.

[0006] The display panel provided in the first aspect of this application has an array substrate and a color filter substrate respectively provided with a first identifier and a second identifier. The first identifier and the second identifier can be aligned with each other, such that the orthographic projection of the first identifier portion is located in the second dimming section, and the orthographic projection of the second identifier portion is located in the first dimming section, thereby assembling the array substrate and the color filter substrate.

[0007] In related technologies, the first and second dimming units are hollowed out, allowing light to pass through both the first dimming unit (except for the portion overlapping with the second marking unit) and the second dimming unit (except for the portion overlapping with the first marking unit), resulting in light leakage on the display panel. However, in this application, the material of the first and / or second dimming units includes a color-changing material. By controlling the color-changing material under a first or second preset condition, the light transmittance of the first and / or second dimming units can be changed. For example, when the first and second marking units need to be aligned, the color-changing material is placed under the first preset condition. At this time, the first and second dimming units allow light to pass through, and the dimming units and marking units can cooperate to align the first and second marking units. After the first and second marking units are aligned, the color-changing material is placed under the second preset condition. At this time, the first and / or second dimming units can block light, reducing or even eliminating the light leakage area of ​​the marking units, thereby reducing the probability of light leakage on the display panel.

[0008] Therefore, this application uses a color-changing material in the dimming part of the marker, which can allow light to pass through or block light. This not only reduces the light leakage area of ​​the marker and lowers the probability of light leakage on the display panel, but also does not affect the accuracy of the alignment between the first and second markers, ensuring that the first and second markers can be accurately aligned.

[0009] Wherein, the orthographic projection of the second marking portion onto the first marking element coincides with the first dimming portion; and / or, the orthographic projection of the second dimming portion onto the first marking element coincides with the first marking portion.

[0010] The first signage component further includes a third dimming portion surrounding the first signage portion and a third signage portion surrounding the third dimming portion. The second signage component further includes a fourth signage portion surrounding the second dimming portion. The orthographic projection of the third signage portion onto the second signage component coincides with the fourth signage portion. The third signage portion and the fourth signage portion are capable of blocking light. The material of either the third dimming portion or the fourth signage portion includes the color-changing material.

[0011] When the material of the fourth marking part includes the color-changing material, the second marking member also includes a light-shielding part disposed between the second dimming part and the fourth marking part.

[0012] The third marking part includes at least two sub-bents spaced apart. When the material of the fourth marking part includes the color-changing material, the fourth marking part includes at least two sub-marking parts spaced apart. The side of the sub-marking part facing the light-shielding part has a positioning groove. The shape of the groove wall of the positioning groove is the same as the shape of the sub-bent. The orthographic projection of the groove wall of the positioning groove onto the first marking part coincides with the sub-bent.

[0013] Wherein, the fourth identification part satisfies at least one of the following conditions:

[0014] The two sub-identifiers are located on the same side of the light-shielding portion;

[0015] The two sub-identifiers are respectively located on opposite sides of the light-shielding part.

[0016] Wherein, when the materials of the second dimming part and the fourth marking part both include color-changing materials, the surface area of ​​the fourth marking part on the side away from the first marking element is greater than the surface area of ​​the second dimming part on the side away from the first marking element.

[0017] Wherein, when the material of the second dimming part includes the color-changing material, the second dimming part covers the first marking part and part of the first dimming part in the orthographic projection of the first marking part.

[0018] A second aspect of this application provides an electronic device, the electronic device including a housing and a display panel provided in the first aspect of this application mounted on the housing.

[0019] The electronic device provided in the second aspect of this application adopts the display panel provided in the first aspect of this application and uses a color-changing material in the dimming part of the marker. By utilizing the property that the color-changing material can allow light to pass through or block light, it can not only reduce the light leakage area of ​​the marker and reduce the probability of light leakage from the display panel, but also ensure that the alignment accuracy of the first marker and the second marker is not affected, thus ensuring that the first marker and the second marker can achieve accurate alignment.

[0020] A third aspect of this application provides a method for assembling a display panel, the method comprising:

[0021] An array substrate and a color filter substrate are provided. One of the array substrate and the color filter substrate is provided with a first identification element, and the other is provided with a second identification element. The first identification element includes a first dimming portion and a first marking portion surrounding the first dimming portion. The second identification element includes a second marking portion and a second dimming portion surrounding the second marking portion. The first marking portion and the second marking portion are capable of blocking light. At least one of the first dimming portion and the second dimming portion is made of a color-changing material. The color-changing material is capable of allowing light to pass through under a first preset condition and is capable of blocking light under a second preset condition.

[0022] The color-changing material is placed under the first preset condition;

[0023] The first identifier and the second identifier are aligned such that the orthographic projection of the first identifier onto the second identifier is located within the second dimming section, and the orthographic projection of the second identifier onto the first identifier is located within the first dimming section, so as to assemble the array substrate and the color filter substrate.

[0024] The color-changing material is placed under the second preset condition.

[0025] The third aspect of this application provides a display panel assembly method that is simple in process and highly operable. By placing the color-changing material under a first preset condition, i.e., allowing the dimming section to transmit light, the first and second identification components are aligned. Furthermore, by placing the color-changing material under a second preset condition, i.e., allowing the dimming section to block light, the light leakage area of ​​the identification components is reduced, or even eliminated.

[0026] Therefore, the assembly method of this application can not only reduce the light leakage area of ​​the marker and reduce the probability of light leakage in the display panel, but also does not affect the accuracy of the alignment between the first marker and the second marker, ensuring that the first marker and the second marker can be accurately aligned.

[0027] A fourth aspect of this application provides a method for manufacturing a display panel, the method comprising:

[0028] Provide a transparent substrate;

[0029] A light-shielding layer is formed on one side of the light-transmitting substrate;

[0030] A filling hole is formed that penetrates the light-shielding layer, exposing the light-transmitting substrate;

[0031] A color-changing material is disposed in the filling hole. The color-changing material can allow light to pass through under a first preset condition and can block light under a second preset condition to obtain an identification element. The identification element includes a dimming part and an identification part. The identification part is formed by the light-shielding layer. The material of the dimming part includes the color-changing material. Thus, an array substrate and a color filter substrate with the identification element are obtained.

[0032] The fourth aspect of this application provides a method for manufacturing a display panel, which is simple in process and highly operable. By forming filling holes in a light-shielding layer and filling them with a color-changing material, an identifier comprising a dimming section and an identification section is obtained. Since the dimming section of the identifier in this application uses a color-changing material, utilizing the property of the color-changing material to allow light to pass through or block light, not only can the light leakage area of ​​the identifier be reduced, lowering the probability of light leakage in the display panel; but it also does not affect the accuracy of the alignment between the first and second identifiers, ensuring that the first and second identifiers can achieve precise alignment.

[0066] This embodiment provides a display panel 1, which includes an array substrate 11 and a color filter substrate 12 stacked together. One of the array substrate 11 and the color filter substrate 12 is provided with a first identifier 13, and the other is provided with a second identifier 14.

[0067] The first sign 13 includes a first dimming part 131 and a first sign part 132 surrounding the periphery of the first dimming part 131. The second sign 14 includes a second sign part 141 and a second dimming part 142 surrounding the periphery of the second sign part 141. The orthographic projection of the first sign part 132 onto the second sign 14 is located within the second dimming part 142, and the orthographic projection of the second sign part 141 onto the first sign 13 is located within the first dimming part 131.

[0068] The first marking part 132 and the second marking part 141 are capable of blocking light. At least one of the first dimming part 131 and the second dimming part 142 is made of a color-changing material. The color-changing material can allow light to pass through under a first preset condition and can block light under a second preset condition.

[0069] Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a particular order.

[0070] The display panel 1 provided in this embodiment is composed of an array substrate 11 and a color filter substrate 12. The array substrate 11 and the color filter substrate 12 are respectively provided with a first identifier 13 and a second identifier 14. The first identifier 13 and the second identifier 14 can be aligned with each other, such that the orthographic projection of the first identifier 132 on the second identifier 14 is located within the second dimming section 142, and the orthographic projection of the second identifier 141 on the first identifier 13 is located within the first dimming section 131, thereby assembling the array substrate 11 and the color filter substrate 12. Optionally, the display panel 1 can be applied to display devices, mobile phones, e-readers, electronic devices, etc.

[0071] The display panel 1 in this embodiment includes an array substrate 11 and a color filter substrate 12 stacked together, with the array substrate 11 mounted on one side of the color filter substrate 12. One of the array substrate 11 and the color filter substrate 12 has a first identifier 13, and the other has a second identifier 14. For example, when the array substrate 11 has the first identifier 13, the color filter substrate 12 has the second identifier 14. Or, for another example, when the array substrate 11 has the second identifier 14, the color filter substrate 12 has the first identifier 13. The first identifier 13 and the second identifier 14 are stacked together.

[0072] Optionally, the array substrate 11 includes a display area and a non-display area disposed around the periphery of the display area, with the first identifier 13 or the second identifier 14 located in the non-display area of ​​the array substrate 11. Optionally, the color filter substrate 12 includes a display area and a non-display area disposed around the periphery of the display area, with the first identifier 13 or the second identifier 14 located in the non-display area of ​​the color filter substrate 12. Optionally, the array substrate 11 includes a first straight portion, a first corner portion, and a second straight portion connected in sequence, with the first identifier 13 or the second identifier 14 disposed in the first corner portion. Optionally, the color filter substrate 12 includes a third straight portion, a second corner portion, and a fourth straight portion connected in sequence, with the first identifier 13 or the second identifier 14 disposed in the second corner portion. In other words, the identifier is located at the corner portion around the periphery of the array substrate 11 and the color filter substrate 12.

[0073] In this embodiment, the first identifier 13 includes a first dimming part 131 and a first identifier part 132 surrounding the periphery of the first dimming part 131. The first dimming part 131 and the second identifier part 141 are used to align with the second identifier 14 to assemble the array substrate 11 and the color filter substrate 12. The first identifier part 132 surrounds the first dimming part 131. Optionally, the first identifier part 132 may be annular, or the first identifier part 132 may surround part of the periphery of the first dimming part 131, or when there are multiple first identifier parts 132, they may be spaced apart around the periphery of the first dimming part 131. This application does not limit the shape of the first dimming part 131 and the first identifier part 132. For example, the shape of the first dimming part 131 and the first identifier part 132 may be quadrilateral, circular, rhomboid, etc.

[0074] Optionally, the material of the first dimming unit 131 may include a color-changing material or a light-transmitting material. Specifically, if the material of the first dimming unit 131 includes a color-changing material, when the color-changing material is under a first preset condition, the first dimming unit 131 can allow light to pass through; when the color-changing material is under a second preset condition, the first dimming unit 131 can block light. If the material of the first dimming unit 131 includes a light-transmitting material, the first dimming unit 131 can allow light to pass through. Additionally, the first dimming unit 131 may also be perforated to allow light to pass through. The first marking unit 132 can block light. Optionally, the material of the first marking unit 132 may include a light-blocking material, such as a black matrix material.

[0075] In this embodiment, the second identifier 14 includes a second identifier portion 141 and a second dimming portion 142 surrounding the periphery of the second identifier portion 141. The second identifier portion 141 and the second dimming portion 142 are used to mate with the first identifier 13 to assemble the array substrate 11 and the color filter substrate 12. The second dimming portion 142 surrounds the second identifier portion 141. Optionally, the shape of the second dimming portion 142 is annular, or the second dimming portion 142 surrounds part of the periphery of the second identifier portion 141, or when there are multiple second dimming portions 142, they are spaced apart at the periphery of the second identifier portion 141. This application does not limit the shape of the second identifier portion 141 and the second dimming portion 142. For example, the shape of the second identifier portion 141 and the second dimming portion 142 can be quadrilateral, circular, rhomboid, etc.

[0076] The second marking portion 141 can block light. Optionally, the material of the second marking portion 141 includes a light-blocking material, such as a black matrix material. Optionally, the material of the second dimming portion 142 includes a color-changing material or a light-transmitting material. Specifically, if the material of the second dimming portion 142 includes a color-changing material, when the color-changing material is under a first preset condition, the second dimming portion 142 can allow light to pass through; when the color-changing material is under a second preset condition, the second dimming portion 142 can block light. If the material of the second dimming portion 142 includes a light-transmitting material, the second dimming portion 142 can allow light to pass through. In addition, the second dimming portion 142 can also be perforated to allow light to pass through.

[0077] At least one of the first dimming unit 131 and the second dimming unit 142 is made of a color-changing material. For example, when the material of the first dimming unit 131 includes a color-changing material, the second dimming unit 142 allows light to pass through but does not include a color-changing material. Alternatively, when the material of the second dimming unit 142 includes a color-changing material, the first dimming unit 131 allows light to pass through but does not include a color-changing material. Or, both the first dimming unit 131 and the second dimming unit 142 are made of a color-changing material.

[0078] The color-changing material is a reversible color-changing material. Optionally, the color-changing material includes at least one of bisbenzothiazole spiropyran derivatives, spiroxazine, fentanyl anhydride, spirothiran, and stearic acid terephthalic acid. Optionally, the first preset condition is to irradiate the color-changing material with ultraviolet light, and the intensity of the ultraviolet light is 5 W / cm². 2 -50W / cm 2 The light exposure time is 30s-100s; or, the color-changing material is heated to a temperature of 120℃-160℃ for 10s-50s. Optionally, the second preset condition is to irradiate the color-changing material with visible light for 20s-60s; or, the color-changing material is cooled to a temperature of 20℃-60℃ for 60s-80s.

[0079] The second marking portion 141 is located within the first dimming portion 131 in the orthographic projection of the first marking member 13. For example, there may be a gap between the second marking portion 141 and the sidewall of the first dimming portion 131 in the orthographic projection of the first marking member 13. In this case, the surface area of ​​the second marking portion 141 facing the first marking member 13 is smaller than the surface area of ​​the first dimming portion 131 facing the second marking member 141. Alternatively, the second marking portion 141 may be attached to the sidewall of the first dimming portion 131 in the orthographic projection of the first marking member 13. In this case, the orthographic projection of the second marking portion 141 in the orthographic projection of the first marking member 13 coincides with the first dimming portion 131. Yet another example is that a portion of the second marking portion 141 in the orthographic projection of the first marking member 13 is located within the first dimming portion 131, and a portion is located within the first positioning portion. In this case, the surface area of ​​the second marking portion 141 facing the first marking member 13 is larger than the surface area of ​​the first dimming portion 131 facing the second marking member 14.

[0080] The first marking portion 132 is located within the second dimming portion 142 in the orthographic projection of the second marking member 14. For example, there may be a gap between the orthographic projection of the first marking portion 132 onto the second marking member 14 and the outer or inner sidewall of the second dimming portion 142. In this case, the surface area of ​​the first marking portion 132 facing the second marking member 14 is smaller than the surface area of ​​the second dimming portion 142 facing the first marking member 132. Alternatively, the orthographic projection of the first marking portion 132 onto the sidewall of the second dimming portion 142 may be aligned with the orthographic projection of the first marking member 142. In this case, the orthographic projection of the first marking portion 132 onto the second marking member 14 coincides with the second dimming portion 142. Yet another example is that a portion of the orthographic projection of the first marking portion 132 onto the second marking member 14 is located within the second dimming portion 142, and a portion is located within the second positioning portion. In this case, the surface area of ​​the first marking portion 132 facing the second marking member 14 is larger than the surface area of ​​the second dimming portion 142 facing the first marking member 13.

[0081] In related technologies, the first dimming unit 131 and the second dimming unit 142 are hollowed out, which allows light to pass through the first dimming unit 131 except for the portion overlapping with the second marking unit 141 and the second dimming unit 142 except for the portion overlapping with the first marking unit 132, thereby causing light leakage in the display panel 1.

[0082] However, the material of the first dimming unit 131 and / or the second dimming unit 142 in this embodiment includes a color-changing material. By controlling the color-changing material to be under a first preset condition or a second preset condition, the light transmittance of the first dimming unit 131 and / or the second dimming unit 142 can be changed. For example, when the first marker 13 and the second marker 14 need to be aligned, the color-changing material is placed under the first preset condition. At this time, the first dimming unit 131 and the second dimming unit 142 can allow light to pass through, and the dimming unit and the marker unit can cooperate with each other to align the first marker 13 and the second marker 14. After the first marker 13 and the second marker 14 are aligned, the color-changing material is placed under the second preset condition. At this time, the first dimming unit 131 and / or the second dimming unit 142 can block light, reduce the light leakage area of ​​the marker, or even eliminate the light leakage area of ​​the marker, thereby reducing the probability of light leakage in the display panel 1.

[0083] Therefore, by using a color-changing material in the dimming part of the sign, this embodiment utilizes the property that the color-changing material can allow light to pass through or block light, which not only reduces the light leakage area of ​​the sign and lowers the probability of light leakage in the display panel 1, but also does not affect the accuracy of the alignment between the first sign 13 and the second sign 14, ensuring that the first sign 13 and the second sign 14 can achieve accurate alignment.

[0084] In one embodiment, the second dimming part 142 corresponding to the first marking part 132 and / or the first dimming part 131 corresponding to the second marking part 141 are filled with a color-changing material, so that the first marking part 13 and the second marking part 14 are aligned. That is, when the array substrate 11 and the color filter substrate 12 are aligned, there is a large light-transmitting area. After the array substrate 11 and the color filter substrate 12 are bonded together, the light-transmitting area is reduced, thus avoiding the risk of light leakage in the narrow bezel or borderless display panel 1.

In one embodiment, the orthographic projection of the second marker portion 141 onto the first marker portion 13 coincides with the first dimming portion 131; and / or, the orthographic projection of the second dimming portion 142 onto the first marker portion 13 coincides with the first marker portion 132.

[0086] In this embodiment, the second marking portion 141 coincides with the first dimming portion 131 in its orthographic projection onto the first marking member 13; in other words, the second marking portion 141 and the first dimming portion 131 are correspondingly provided. Optionally, the second marking portion 141 and the first dimming portion 131 have the same shape. The second dimming portion 142 coincides with the first marking portion 132 in its orthographic projection onto the first marking member 13; in other words, the second dimming portion 142 and the first marking portion 132 are correspondingly provided. Optionally, the second dimming portion 142 and the first marking portion 132 have the same shape.

Figure 3 The width of the annular portion 132 (as shown in W1) is 50μm-80μm. Figure 3 (As shown in D1) is 10μm-20μm. The length of the first marking portion 132 refers to the maximum dimension of the first marking portion 132 in the length direction of the first marking member 13. The width of the first marking portion 132 refers to the maximum dimension of the first marking portion 132 in the width direction of the first marking member 13. The annular width of the first marking portion 132 refers to the difference between the distance from the outer wall of the first marking portion 132 to the midpoint of the first marking portion 132 and the distance from the inner wall of the first marking portion 132 to the midpoint of the first marking portion 132.

[0088] Optionally, the length of the second dimming unit 142 ( Figure 4 The width of the second dimming section 142 (as shown in H2) is 50μm-80μm. Figure 4 The width of the annular section 142 (as shown in W2) is 50μm-80μm. Figure 4 (As shown in D2) is 10μm-20μm. The length of the second dimming part 142 refers to the maximum dimension of the second dimming part 142 in the length direction of the second marking member 14. The width of the second dimming part 142 refers to the maximum dimension of the second dimming part 142 in the width direction of the second marking member 14. The annular width of the second dimming part 142 refers to the difference between the distance from the outer wall of the second dimming part 142 to the midpoint of the second dimming part 142 and the distance from the inner wall of the second dimming part 142 to the midpoint of the second dimming part 142.

[0089] In this embodiment, the second marking part 141 is correspondingly disposed to the first dimming part 131, and the second dimming part 142 is correspondingly disposed to the first marking part 132. Therefore, regardless of whether the material of the first dimming part 131 and / or the second dimming part 142 includes a color-changing material, the second marking part 141 and the first dimming part 131, and the second dimming part 142 and the first marking part 132 can overlap with each other, further reducing the light leakage area of ​​the marking element, or even eliminating the light leakage area of ​​the marking element, and reducing the probability of light leakage phenomenon in the display panel 1.

[0090] Please refer to this as well. Figures 1-4 ,and Figure 9 and Figure 10 , Figure 9 Provided under the first preset conditions for an embodiment of this application Figure 3 The first identification and Figure 4 Top view of the second marker. Figure 3 . Figure 10 for Figure 7 A cross-sectional view showing the alignment of the first and second markers. In one embodiment, when the material of the second dimming unit 142 includes the color-changing material, the orthographic projection of the second dimming unit 142 onto the first marker 132 covers the first marker 132 and a portion of the first dimming unit 131.

[0091] In this embodiment, the second dimming unit 142 corresponds to both the first marking unit 132 and a portion of the first dimming unit 131. In other words, the surface area of ​​the second dimming unit 142 facing the first marking member 13 is greater than the surface area of ​​the first marking member 132 facing the second marking member 14. Therefore, when the second dimming unit 142 can block light, it can completely cover and block the first marking member 132, and also cover and block a portion of the first dimming unit 131.

[0092] Optionally, the second dimming unit 142 corresponds to the annular width of the first dimming unit 131 (e.g., Figure 7 (As shown in B1) is 3μm-8μm. Further optionally, the annular width of the second dimming unit 142 corresponding to the first dimming unit 131 is 5μm. Here, the annular width of the second dimming unit 142 corresponding to the first dimming unit 131 can also be understood as the size by which the second dimming unit 142 protrudes from the first dimming unit 132 onto the orthographic projection surface of the first identifier 13.

[0093] Therefore, by adjusting the correspondence between the second dimming unit 142 and the first marker 13, this embodiment ensures that the second dimming unit 142 can cover both the first marker 132 and part of the first dimming unit 131, thereby preventing light from passing through the stacked first marker 13 and second marker 14, eliminating light leakage areas of the markers, and reducing the probability of light leakage in the display panel 1. On the other hand, since the second dimming unit 142 can cover both the first marker 132 and part of the first dimming unit 131, it allows for operational errors when aligning the first marker 132, reducing the operational difficulty of aligning the second dimming unit 142 and the first marker 132.

[0095] In one embodiment, the first sign 13 further includes a third dimming portion 133 surrounding the periphery of the first sign portion 132 and a third sign portion 134 surrounding the periphery of the third dimming portion 133. The second sign 14 further includes a fourth sign portion 143 surrounding the periphery of the second dimming portion 142. The orthographic projection of the third sign portion 134 onto the second sign 14 coincides with the fourth sign portion 143. The third sign portion 134 and the fourth sign portion 143 are capable of blocking light, and the material of one of the third dimming portion 133 and the fourth sign portion 143 includes the color-changing material.

[0096] When the material of the fourth marking part 143 includes the color-changing material, the second marking member 14 further includes a light-shielding part 144 disposed between the second dimming part 142 and the fourth marking part 143.

[0097] In this embodiment, the first identifier 13 further includes a third dimming portion 133 surrounding the periphery of the first identifier portion 132, and a third identifier portion 134 surrounding the periphery of the third dimming portion 133. The third dimming portion 133 and the third identifier portion 134 are used to mate with the second identifier 14 to assemble the array substrate 11 and the color filter substrate 12. The first identifier portion 132 surrounds the first dimming portion 131. Optionally, the third dimming portion 133 may be annular in shape, or may surround a portion of the periphery of the first identifier portion 132, or when there are multiple third dimming portions 133, they may be spaced apart around the periphery of the first identifier portion 132. Optionally, the third identifier portion 134 may be annular in shape, or may surround a portion of the periphery of the third dimming portion 133, or when there are multiple third identifier portions 134, they may be spaced apart around the periphery of the third dimming portion 133. This application does not limit the shape of the third dimming section 133 and the third dimming section 133. For example, the shape of the third dimming section 133 and the third dimming section 133 may be a quadrilateral, a circle, a rhombus, etc.

[0098] Optionally, the material of the third dimming unit 133 may include a color-changing material or a light-transmitting material. Specifically, if the material of the third dimming unit 133 includes a color-changing material, when the color-changing material is under a first preset condition, the first dimming unit 131 can allow light to pass through; when the color-changing material is under a second preset condition, the third dimming unit 133 can block light. If the material of the third dimming unit 133 includes a light-transmitting material, the third dimming unit 133 can allow light to pass through. Additionally, the third dimming unit 133 may also be perforated to allow light to pass through. The third marking unit 134 can block light. Optionally, the material of the third marking unit 134 may include a light-blocking material, such as a black matrix material.

[0099] In this embodiment, the second identifier 14 further includes a fourth identifier 143 surrounding the periphery of the second dimming section 142. The fourth identifier 143 is used to align with the first identifier 13 to assemble the array substrate 11 and the color filter substrate 12. The fourth identifier 143 surrounds the second dimming section 142. Optionally, the fourth identifier 143 may be annular, or may surround a portion of the periphery of the second dimming section 142, or when there are multiple fourth identifiers 143, they may be spaced apart at intervals around the periphery of the second dimming section 142. Optionally, the third identifier 134 may be annular, or may surround a portion of the periphery of the third dimming section 133, or when there are multiple third identifiers 134, they may be spaced apart at intervals around the periphery of the third dimming section 133. This application does not limit the shape of the fourth identifier 143; for example, the shape of the fourth identifier 143 may be quadrilateral, circular, rhomboid, etc.

[0100] Optionally, the material of the fourth marking part 143 may include a color-changing material or a light-blocking material. Specifically, if the material of the fourth marking part 143 includes a color-changing material, when the color-changing material is under a first preset condition, the fourth marking part 143 allows light to pass through; when the color-changing material is under a second preset condition, the fourth marking part 143 can block light. If the material of the fourth marking part 143 includes a light-blocking material, the fourth marking part 143 can block light.

[0101] The material of either the third dimming unit 133 or the fourth marking unit 143 includes a color-changing material. For example, such as Figures 11-14 When the material of the third dimming unit 133 includes a color-changing material, the fourth marking unit 143 can block light and does not include the color-changing material. For example, such as... Figure 11 , Figures 15-17 When the material of the fourth marking section 143 includes a color-changing material, the third dimming section 133 can allow light to pass through without including the color-changing material.

[0102] Furthermore, when the material of the fourth marking part 143 includes a color-changing material, the second marking member 14 also includes a light-shielding part 144 disposed between the second dimming part 142 and the fourth marking part 143. In other words, the light-shielding part 144 surrounds the periphery of the second dimming part 142, and the fourth marking part 143 surrounds the periphery of the light-shielding part 144. Since the material of the fourth marking part 143 includes a color-changing material, the color-changing material in the first preset state allows light to pass through, and the light-shielding part 144 can separate the light-transmitting fourth marking part 143 from the light-transmitting second dimming part 142, so as to facilitate the alignment of the first marking member 13 and the second marking member 14. Optionally, the light-shielding part 144 coincides with the orthographic projection of the second marking member 14 and the third dimming part 133.

[0103] The third marking portion 134 coincides with the fourth marking portion 143 in the orthographic projection of the second marking member 14, or in other words, the third marking portion 134 and the fourth marking portion 143 are correspondingly provided. Optionally, the third marking portion 134 and the fourth marking portion 143 have the same shape.

[0104] In related technologies, the third dimming unit 133 is hollowed out, allowing light to pass through and causing light leakage in the display panel 1. However, in this embodiment, the material of the third dimming unit 133 or the fourth marking unit 143 includes a color-changing material. The light transmittance of the third dimming unit 133 or the fourth marking unit 143 can be changed by controlling the color-changing material to be under a first preset condition or a second preset condition. For example, when the first marking member 13 and the second marking member 14 need to be aligned, the color-changing material is placed under the first preset condition. At this time, the third dimming unit 133 or the fourth marking unit 143 can allow light to pass through, and the dimming unit and the marking unit can cooperate with each other to align the first marking member 13 and the second marking member 14. When the first marker 13 and the second marker 14 are aligned, the color-changing material is placed under the second preset condition. At this time, the third dimming part 133 or the fourth marker part 143 can block the light, reduce the light leakage area of ​​the marker, or even eliminate the light leakage area of ​​the marker, thereby reducing the probability of light leakage phenomenon in the display panel 1.

[0105] Therefore, this embodiment uses a color-changing material in the dimming or marking section of the marker, utilizing the property of the color-changing material to allow light to pass through or block light, thereby reducing the light leakage area of ​​the marker and lowering the probability of light leakage on the display panel 1. Furthermore, based on the alignment of the first marking section 132 and the second marking section 141, this embodiment further improves the alignment accuracy of the first marking section 13 and the second marking section 14 by adding a third marking section 134 and a fourth marking section 143 for double alignment; and by adding a third dimming section 133, the marker can be controlled, adjusted, and moved during the alignment process of the first marking section 13 and the second marking section 14, thereby further improving the alignment accuracy of the first marking section 13 and the second marking section 14.

[0106] Please refer to this as well. Figure 11 , Figures 15-17 In one embodiment, when both the second dimming part 142 and the fourth marking part 143 are made of color-changing material, the surface area of ​​the fourth marking part 143 on the side away from the first marking member 13 is greater than the surface area of ​​the second dimming part 142 on the side away from the first marking member 13.

[0107] In this embodiment, the surface area of ​​the second dimming part 142 is larger than the surface area of ​​the fourth marking part 143, so that when the color-changing material is under the first preset condition, the light-transmitting area of ​​the second dimming part 142 is larger than the light-transmitting area of ​​the fourth marking part 143. When the first marking member 13 and the second marking member 14 are aligned, the fourth marking part 143 with a larger light-transmitting area is more convenient to observe whether there is an alignment deviation between the first marking member 13 and the second marking member 14, and to facilitate the control, adjustment and movement of the marking members, thereby further improving the accuracy of the alignment between the first marking member 13 and the second marking member 14.

[0108] Optionally, the length of the fourth identifier 143 (e.g.) Figure 15 The width of the fourth identifier 143 (as shown in H3) is 100μm-150μm. Figure 15 The width of the annular portion of the fourth identifier 143 (as shown in W3) is 100μm-150μm. Figure 15 (As shown in D3) is 10μm-20μm. The length of the fourth marking portion 143 refers to the maximum dimension of the fourth marking portion 143 in the length direction of the second marking member 14. The width of the fourth marking portion 143 refers to the maximum dimension of the fourth marking portion 143 in the width direction of the second marking member 14. The annular width of the fourth marking portion 143 refers to the difference between the distance from the outer wall of the fourth marking portion 143 to the midpoint of the fourth marking portion 143 and the distance from the inner wall of the fourth marking portion 143 to the midpoint of the fourth marking portion 143.

[0109] Optionally, please refer to the following as well. Figures 13-14 ,and Figures 18-19 , Figure 18 Provided under the first preset conditions for an embodiment of this application Figure 11 The first identification and Figure 15 Top view of the second marker. Figure 2 . Figure 19 for Figure 18 A cross-sectional view showing the alignment of the first and second markers. In one embodiment, when the material of the second dimming unit 142 includes the color-changing material, the second dimming unit 142, in its orthographic projection onto the first marker 13, covers the first marker 132, a portion of the first dimming unit 131, and a portion of the third dimming unit 133.

[0110] In this embodiment, the second dimming unit 142 corresponds to the first marking unit 132, a portion of the first dimming unit 131, and a portion of the third dimming unit 133. In other words, the surface area of ​​the second dimming unit 142 facing the first marking member 13 is greater than the surface area of ​​the first marking unit 132 facing the second marking member 14. Therefore, when the second dimming unit 142 can block light, it can completely cover and block the first marking unit 132, a portion of the first dimming unit 131, and a portion of the third dimming unit 133.

[0111] Optionally, the second dimming unit 142 corresponds to the annular width of the third dimming unit 133 (e.g., Figure 14 and Figure 19 (As shown in B2) is 3μm-8μm. Further optionally, the annular width of the second dimming section 142 corresponding to the third dimming section 133 is 5μm. Here, the annular width of the second dimming section 142 corresponding to the third dimming section 133 can also be understood as the size by which the second dimming section 142 protrudes from the first marking section 132 onto the orthographic projection surface of the first marking member 13 towards the third dimming section 133.

[0112] Therefore, by adjusting the correspondence between the second dimming unit 142 and the first marker 13, this embodiment ensures that the second dimming unit 142 can cover the first marker 132, a portion of the first dimming unit 131, and a portion of the third dimming unit 133, thereby preventing light from passing through the stacked first marker 13 and second marker 14, eliminating light leakage areas of the markers, and reducing the probability of light leakage in the display panel 1. On the other hand, since the second dimming unit 142 can cover the first marker 132, a portion of the first dimming unit 131, and a portion of the third dimming unit 133, operational errors are allowed when the first marker 132 is aligned, reducing the operational difficulty of aligning the second dimming unit 142 and the first marker 132.

[0113] Optionally, please refer to the following as well. Figure 16 and Figure 20 , Figure 20 for Figure 16 Cross-section of the alignment of the first marker 13 and the second marker 14 Figure 2 In one embodiment, when the material of the fourth marking portion 143 includes the color-changing material, the fourth marking portion 143, in the orthographic projection of the first marking member 13, covers the third marking portion 134 and a portion of the third dimming portion 133.

[0114] In this embodiment, the fourth marking part 143 corresponds to both the third marking part 134 and a portion of the third dimming part 133. In other words, the surface area of ​​the fourth marking part 143 facing the first marking member 13 is greater than the surface area of ​​the third marking part 134 facing the second marking member 14. Therefore, when the fourth marking part 143 can block light, it can completely cover and block the third marking part 134, and also cover and block a portion of the third dimming part 133.

[0115] Optionally, the fourth marking portion 143 corresponds to the annular width of the third dimming portion 133 (e.g., Figure 20 (As shown in B3) is 3μm-8μm. Further optionally, the annular width of the fourth marking portion 143 corresponding to the third dimming portion 133 is 5μm. Here, the annular width of the fourth marking portion 143 corresponding to the third dimming portion 133 can also be understood as the size by which the fourth marking portion 143 protrudes from the third dimming portion 133 onto the orthographic projection surface of the first marking member 13.

[0116] Therefore, by adjusting the correspondence between the fourth marking part 143 and the first marking part 13, this embodiment ensures that the fourth marking part 143 can cover both the third marking part 134 and part of the third dimming part 133, thereby preventing light from passing through the stacked first marking part 13 and second marking part 14, eliminating light leakage areas of the marking parts, and reducing the probability of light leakage in the display panel 1. On the other hand, since the fourth marking part 143 can cover both the third marking part 134 and part of the third dimming part 133, operational errors are allowed when the third marking part 134 is aligned, reducing the operational difficulty of aligning the third dimming part 133 and the fourth marking part 143.

[0117] Please refer to this as well. Figure 11 , Figures 21-23 , Figure 21 Top view of the second identifier provided in one embodiment of this application Figure 4 . Figure 22 Provided under the first preset conditions for an embodiment of this application Figure 11 The first identification and Figure 21 The top view of the second identification piece. Figure 23 for Figure 22 A cross-sectional view showing the alignment of the first and second identification components.

[0118] In one embodiment, the third marking portion 134 includes at least two sub-bent portions 1341 spaced apart. When the material of the fourth marking portion 143 includes the color-changing material, the fourth marking portion 143 includes at least two sub-marking portions 1431 spaced apart. The side of the sub-marking portion 1431 facing the light-shielding portion 144 has a positioning groove 1431a. The shape of the groove wall of the positioning groove 1431a is the same as the shape of the sub-bent portion 1341. The orthographic projection of the groove wall of the positioning groove 1431a onto the first marking member 13 coincides with the sub-bent portion 1341.

[0119] The third marking portion 134 in this embodiment includes at least two sub-bends 1341 spaced apart. The sub-bends 1341 can be understood as annular corners. The fourth marking portion 143 includes at least two sub-marking portions 1431 spaced apart. The sub-marking portions 1431 are correspondingly arranged with the sub-bends 1341, or in other words, the orthographic projection of the sub-marking portion 1431 onto the first marking member 13 coincides with the sub-bend 1341. Optionally, the number of sub-marking portions 1431 is 2-6.

[0120] Specifically, the sub-marking portion 1431 has a positioning groove 1431a on the side facing the light-shielding portion 144, and the shape of the groove wall of the positioning groove 1431a is the same as the shape of the sub-bending portion 1341. Optionally, the shape of the groove wall of the positioning groove 1431a and the shape of the sub-bending portion 1341 can be L-shaped, W-shaped, etc. The groove wall of the positioning groove 1431a, in the orthographic projection of the first marking member 13, coincides with the inner sidewall of the sub-bending portion 1341 facing the light-shielding portion 144.

[0121] This embodiment reduces the surface area of ​​the fourth marking portion 143 facing the first marking member 13 by aligning the fourth marking portion 143 with the sub-bending portion 1341 of the third marking portion 134. This reduces the light-transmitting area of ​​the fourth marking portion 143, further reducing the light leakage area of ​​the marking member and further lowering the probability of light leakage in the display panel 1. Furthermore, by aligning the sub-markers with the sub-bending portions 1341, the alignment accuracy of the first marking member 13 and the second marking member 14 can be further improved, thereby improving the alignment accuracy of the array substrate 11 and the color filter substrate 12.

[0122] Please refer to this as well. Figure 11 , Figures 21-23 In one embodiment, the fourth marking portion 143 satisfies at least one of the following conditions: the two sub-marking portions 1431 are located on the same side of the light-shielding portion 144; and / or, the two sub-marking portions 1431 are located on opposite sides of the light-shielding portion 144.

[0123] In this embodiment, the two sub-identifier portions 1431 can be arranged side-by-side on the same side of the light-shielding portion 144. For example, the two sub-identifier portions 1431 can be arranged side-by-side, staggered, or symmetrically arranged along the axis of the light-shielding portion 144. The two sub-identifier portions 1431 can be respectively provided on opposite sides of the light-shielding portion 144. Optionally, when the third identifier portion 134 is a quadrilateral ring structure, the third identifier portion 134 has four sub-bent portions 1341, and the number of sub-identifier portions 1431 is four, respectively provided on the four sub-bent portions 1341 of the quadrilateral ring structure. Therefore, this embodiment improves the alignment accuracy of the first identifier 13 and the second identifier 14 by limiting the position of the sub-identifier portions 1431, thereby improving the alignment accuracy of the array substrate 11 and the color filter substrate 12.

[0124] This application also provides an electronic device, which includes a housing and a display panel 1 provided above in this application mounted on the housing.

[0125] The electronic device provided in this embodiment uses the display panel 1 provided in this application above. The color-changing material is used in the dimming part of the marker. By utilizing the property that the color-changing material can allow light to pass through or block light, it can not only reduce the light leakage area of ​​the marker and reduce the probability of light leakage phenomenon of the display panel 1, but also does not affect the accuracy of the alignment of the first marker 13 and the second marker 14, ensuring that the first marker 13 and the second marker 14 can achieve accurate alignment.

[0126] This application also provides a method for assembling the display panel 1. Please refer to... Figure 24 , Figure 24 This is a process flow diagram of the assembly method of a display panel according to one embodiment of this application. This embodiment provides an assembly method for a display panel 1, which includes steps S100, S200, S300, and S400. Detailed descriptions of steps S100, S200, S300, and S400 are as follows.

[0127] S100, an array substrate 11 and a color filter substrate 12 are provided. One of the array substrate 11 and the color filter substrate 12 is provided with a first identifier 13, and the other is provided with a second identifier 14. The first identifier 13 includes a first dimming part 131 and a first marking part 132 surrounding the first dimming part 131. The second identifier 14 has a second marking part 141 and a second dimming part 142 surrounding the second marking part 141. The first marking part 132 and the second marking part 141 are capable of blocking light. At least one of the first dimming part 131 and the second dimming part 142 is made of a color-changing material. The color-changing material can allow light to pass through under a first preset condition and can block light under a second preset condition.

[0128] The array substrate 11, color filter substrate 12, first identifier 13, and second identifier 14 in this embodiment are as described above and will not be repeated here.

[0129] S200, the color-changing material is placed under the first preset condition.

[0130] Optionally, the step of placing the color-changing material under the first preset condition includes:

[0131] The color-changing material is irradiated with ultraviolet light, the intensity of which is 5 W / cm². 2 -50W / cm 2 The light exposure time is 30s-100s; or, the color-changing material is heated to a temperature of 120℃-160℃ for 10s-50s.

[0132] S300, the first identifier 13 is aligned with the second identifier 14, such that the orthographic projection of the first identifier 132 onto the second identifier 14 is located within the second dimming section 142, and the orthographic projection of the second identifier 141 onto the first identifier 13 is located within the first dimming section 131, so as to assemble the array substrate 11 and the color filter substrate 12.

[0133] S400, the color-changing material is placed under the second preset condition.

[0134] Optionally, the step of placing the color-changing material under the second preset condition includes:

[0135] The color-changing material is irradiated with visible light for 20-60 seconds; or, the color-changing material is cooled to a temperature of 20-60°C for 60-80 seconds.

[0136] The assembly method for the display panel 1 provided in this embodiment is simple in process and highly operable. By placing the color-changing material under a first preset condition, that is, allowing the dimming part to transmit light, the first marker 13 and the second marker 14 are aligned with each other. Furthermore, by placing the color-changing material under a second preset condition, that is, allowing the dimming part to block light, the light leakage area of ​​the marker is reduced, or even eliminated.

[0137] Therefore, the assembly method of this embodiment can not only reduce the light leakage area of ​​the marker and reduce the probability of light leakage in the display panel 1, but also does not affect the accuracy of the alignment of the first marker 13 and the second marker 14, ensuring that the first marker 13 and the second marker 14 can be accurately aligned.

[0138] This application also provides a method for manufacturing the display panel 1. Please refer to it as well. Figures 1-6 ,and Figures 25-28 , Figure 25 This is a process flow diagram of the method for preparing the display panel 1 according to one embodiment of this application. Figure 26 This is a schematic diagram of process S20 of the method for manufacturing a display device according to one embodiment of this application. Figure 27 This is a schematic diagram of process S30 of the method for manufacturing a display device according to one embodiment of this application. Figure 28 This is a schematic diagram of process S40 of the method for manufacturing a display device according to an embodiment of this application.

[0139] This embodiment provides a method for manufacturing a display panel 1, the method comprising steps S10, S20, S30, and S40. Detailed descriptions of steps S10, S20, S30, and S40 are as follows.

[0140] S10 provides a light-transmitting substrate 15.

[0141] Optionally, the light-transmitting substrate 15 has a light transmittance greater than 95%. Optionally, the light-transmitting substrate 15 is made of SiO2 glass substrate.

[0142] like Figure 26 As shown, in S20, a light-shielding layer 16 is formed on one side of the light-transmitting substrate 15.

[0143] The light-shielding layer 16 is made of a light-shielding material, such as a black matrix material. Optionally, the light-shielding material is coated on the light-transmitting substrate 15 to form the light-shielding layer 16.

[0144] like Figure 27 As shown, in step S30, a filling hole 161 is formed through the light-shielding layer 16, exposing the light-transmitting substrate 15.

[0145] Alternatively, the filling hole 161 can be formed by photolithography, exposure and development.

[0146] like Figure 28 As shown in step S40, a color-changing material 17 is provided in the filling hole 161. The color-changing material 17 can allow light to pass through under a first preset condition and can block light under a second preset condition to obtain an identification element. The identification element includes a dimming part and an identification part. The identification part is formed by the light-shielding layer 16. The material of the dimming part includes the color-changing material 17. Thus, an array substrate 11 and a color filter substrate 12 with the identification element are obtained.

[0147] The identification components include a first identification component 13 and a second identification component 14 (e.g., Figures 1-6 (As shown). The relevant structures of the first identifier 13 and the second identifier 14 are as described above and will not be repeated here.

[0148] The method for manufacturing a display panel provided in this embodiment is simple and highly operable. By forming filling holes in a light-shielding layer and filling them with a color-changing material, an identification element including a dimming section and an identification section is obtained. Since the dimming section of the identification element in this application uses a color-changing material, utilizing the property of the color-changing material to allow light to pass through or block light, not only can the light leakage area of ​​the identification element be reduced, lowering the probability of light leakage in the display panel; but it also does not affect the accuracy of the alignment between the first and second identification elements, ensuring that the first and second identification elements can achieve precise alignment.

[0149] The above provides a detailed description of the embodiments provided in this application. This document elucidates and explains the principles and implementation methods of this application. The above description is only intended to help understand the methods and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
