As described in the background, a partition structure in a conventional OLED display panel serves as an evaporation limit and an encapsulation limit for light-emitting structures. During evaporation, light-emitting layers and the cathodes of the light-emitting structures are separated by the partition structure, and the cathodes are electrically connected through the partition structure, so that the OLED display panel is easy to manufacture and has a reduced thickness. However, the touch layer of the conventional OLED display panel integrates the touch function in an On-cell manner, which requires at least four masks for etching operations during manufacturing, resulting in technical problems such as high cost and large stack thickness, which causes a relatively high cost and a relatively large thickness of the OLED display panel.
To address the foregoing problems, embodiments of the present disclosure provide a display panel, a method for manufacturing the same, and a display device using the same. First ring grooves are defined in a partition structure so as to divide the partition structure into a first structure and second structures, and the second structures are located in the first ring grooves. The first touch structure and the second touch structure are independent of each other and form a mutual capacitance through the bridge of the second structure. In this way, compared to the conventional On-cell manner for integrating the touch function using four masks, in the embodiments of the present disclosure, one mask for preparing the partition structure is improved, and then an In-cell mutual capacitance touch control can be realized by using one more mask, so that the manufacturing cost is relatively low and the thickness of the product is relatively thin.
Referring to
It should be noted that the substrate 100 may be an array substrate 110. The array substrate 110 includes an array driver circuit. The partition structure 200 may be grid-shaped, multiple ring-like structures, or the like. Adjacent light-emitting structures 300 are separated by the partition structure 200. The plurality of light-emitting structures 300 may include a plurality of first light-emitting structures 310 that emit red light, a plurality of second light-emitting structures 320 that emit blue light, and a plurality of third light-emitting structures 330 that emit green light. The first light-emitting structures 310, the second light-emitting structures 320, and the third light-emitting structures 330 are alternately arranged. Each light-emitting structure 300 includes an anode, a light-emitting layer, and a cathode. The anode and the cathode may be made of at least one of an indium tin oxide or an indium zinc oxide. The light-emitting layer may be an organic layer. An array driving circuit on the substrate 100 is electrically connected to the anode of each of the light-emitting structures and is configured to control a drive voltage applied between the anode and the cathode of each of the light-emitting structures, so that the light-emitting structures 300 emit light and the display panel 10 performs the display function.
The insulating layer 400 may be made of carbon oxide, nitrogen oxide, boron oxide, or the like, which is deposited using Chemical Vapor Deposition (CVD). The touch layer 500 may be made of metal, metal oxide, mixture containing metals, or the like. In some embodiments, one of the first touch structure 510 and the second touch structure 520 forms a sensing touch channel, and the other one of the first touch structure 510 and the second touch structure 520 forms a drive touch channel. To facilitate subsequent description, the first direction Y is defined as the longitudinal direction, the second direction X is defined as the transverse direction, and the first direction Y is perpendicular to the second direction X. A third direction Z is perpendicular to the substrate 100, and the third direction Z is perpendicular to the first direction Y and the second direction X. It should be understood that the protection scope of the present disclosure is not limited thereto. In other embodiments, the first direction Y and the second direction X may also be interchanged.
According to the aforementioned display panel 10, the partition structure 200 is divided into the first structure 230 and the second structures 240 by the first ring grooves 220, and the second structures are located in the first ring grooves 220. The first touch structure 510 and the second touch structure 520 of the touch layer 500 that are independent of each other form a mutual capacitance through the bridge of the second structure 240. Therefore, one mask is used for preparing the partition structure 200, and one mask is used for preparing the touch layer 500. The mutual capacitance between the first touch structure 510 and the second touch structure 520 can be realized only by using the second structure 240. Additionally, the touch layer 500 is disposed on the insulating layer 400, so that an In-cell mutual capacitance touch control can be realized, and the aforementioned display panel 10 can be manufactured at a low cost and with a thin thickness.
In the embodiments of the present disclosure, the partition structure 200 is divided into the first structure 230 that separates adjacent light-emitting structures 300 and the second structures 240 that serve as the bridge for forming the mutual capacitance between the first touch structures 510 and the second touch structures 520, such that the display panel 10 has reduced stacked layers and is relatively thin. In addition, by simply making adaptive adjustments to the mask for preparing the partition structure 200, the touch layer 500 can be prepared by a single mask, with reduced manufacturing processes and low manufacturing cost.
In an embodiment, referring to
In an embodiment, the second structure 240 and the first structure 230 are insulated from each other to prevent the second structure 240 and the first structure 230 from being affected by each other.
In an embodiment, the second structure 240 extends along the second direction X and is disposed between two light-emitting structures 300 that are adjacent along the first direction Y, such that the plurality of first touch structures 510 respectively extending above the second structures 240 are disposed at intervals along the first direction Y.
In this way, by limiting the specific positions of the second structures 240 and the first structure 230, the first ring grooves 220 will not affect the partitioned openings 210, and the second structures 240 configured to achieve the electrical connection of the first touch structures 510 after bridging do not affect the partition effect of the first structure 230 on adjacent light-emitting structures 300. In addition, the above position setting facilitates the setting of the partition structure 200.
In an embodiment, referring to
In an embodiment, the length of the second structure 240 in the second direction X may be greater than the length of one light-emitting structure 300, and the length of the second structure 240 in the second direction X may also be greater than the total length of the plurality of light-emitting structures 300, so as to adapt to different dimension forms of the second structure 240.
In an embodiment, the plurality of second structures 240 are disposed at intervals along the first direction Y, such that there is only one second structure 240 in the second direction X. There are two first touch structures 510 in the second direction X, and the two first touch structures 510 are electrically connected after being bridged by the second structure 240.
In an embodiment, a part of the second structures 240 are arranged at intervals along the first direction Y, and another part of the second structures 240 are arranged at intervals along the second direction X, so that there are a plurality of the second structures 240 in the second direction X. A plurality of first touch structures 510 extend in the second direction X, and each two of the first touch structures 510 are electrically connected after being bridged by the second structures 240, thus achieving the electrical connection of all the first touch structures 510 in the second direction X.
In an embodiment, an orthographic projection of the second structure 240 in the second direction X intersects an orthographic projection of the second touch structure 520 in the second direction X, such that the second touch structure 520 are arranged above the second structure 240, thereby achieving the mutual capacitance between the first touch structure 510 and the second touch structure 520 through bridging.
In this way, by limiting the position relationship and the dimension relationship between the second structures 240 and adjacent light-emitting structures 300 in the second direction X, the second structures 240 does not affect the definition of the partitioned openings 210 by the partition structure 200, and adjacent light-emitting structures 300 are still separated by the first structure 230. The first touch structures 510 are arranged by utilizing the second structures 240 disposed between adjacent light-emitting structures 300 distributed along the first direction Y. The second touch structures 520 are arranged by utilizing the first structure 230 and second structures 240 that are disposed between adjacent light-emitting structures 300 distributed in the second direction X. Therefore, the light-emitting function layer and the touch control layer 500 can make full use of the partition structure 200.
In an embodiment, referring to
In an embodiment, the length of the first structure 230 in the first direction Y is greater than the length of the light-emitting function layer, so that the first structure 230 is a grid structure, and the first structure 230 can separate all of the light-emitting structures 300 in the first direction Y, respectively.
In this way, by limiting the dimension relationship between the first structure 230 and the light-emitting structure 300 in the first direction Y, the setting manner of the partitioned opening 210 in the first direction Y can be determined, which facilitates the formation of the partitioned opening 210 and prevents the introduction of the first ring groove 220 from affecting the partition function of the partition structure 200.
In an embodiment, two first touch structures 510 are disposed at intervals along the second direction X above the first structure 230, and the two first touch structures 510 extend above the second structure 240. The two first touch structures 510 are electrically connected to the second structure 240 to form a bridge, such that the two first touch structures 510 are electrically connected after being bridged by the second structure 240.
In an embodiment, in the second direction X, the number of the second structures 240 is less than the number of the first touch structures 510, so that both ends of the second structure 240 along the second direction X can be configured to carry the first touch structure 510, which makes the structure simpler and easy to set.
In an embodiment, in the second direction X, one second structure 240 and two first touch structures 510 are provided. In this case, the two first touch structures 510 are located at both ends of the insulating layer 400 along the second direction X, so as to further simplify the setting of the first touch structure 510 and the second structure 240.
In an embodiment, in the second direction X, the number of the second structures 240 is N that is greater than 1, and the number of the first touch structures 510 is N+1. This relationship enables a correspondence design of one mask used to prepare the partition structure 200 and another mask used to prepare the touch layer 500, thus facilitating the correspondence setting of the second structure 240 and the first touch structure 510.
In this way, by limiting that each second structure 240 has two first touch structures 510 located thereon and limiting the relative position relationship between the first touch structure 510 and the partition structure 200, a bridging connection between the plurality of first touch structures 510 can be realized conveniently and reliably.
In an embodiment, referring to
In an embodiment, in the second direction X, the second touch structures 520 above the same second structures 240 are located between the first touch structures 510, so as to facilitate the relative setting of the second touch structures 520 and the first touch structures 510. In addition, the second touch structures 520 and the first touch structures 510 on the same second structure 240 are spaced apart.
In an embodiment, the first ring grooves 220 extend along the second direction X, and the second touch structures 520 extend above the first structure 230, such that the plurality of second structures 240 are spaced apart along the first direction Y, and the first structure 230 is located between these second structures 240. The second touch structures 520 extend above the first structure 230, so that the second touch structures 520 span the first ring grooves 220 and cover the second structures 240 and the first structure 230, so as to ensure the continuity of the second touch structure 520 in the first direction Y.
In this way, the plurality of second touch structures 520, the plurality of first touch structures 510, and the plurality of second structures 240 form a grid structure, and each intersection point of the grid structure corresponds to a touch structure extending along the second direction X, a second structure 240, and a first touch structure 510 extending along the first direction Y, so that a unique touch position can be determined, facilitating the realization of the mutual capacitance between the first touch structures 510 and the second touch structures 520 by bridging, and the reliability and accuracy of the mutual capacitance between the first touch structures 510 and the second touch structures 520 by bridging are high.
Referring to
In an embodiment, an orthographic projection of the second structure 240 in the second direction X does not exceed an orthographic projection of the light-emitting function layer in the second direction X, so that there is enough space in the second direction X to arrange the first ring groove 220, thus ensuring that the areas at both ends of the first structure 230 in the second direction X are suitable for setting the first touch structure 510, thereby improving the reliability of the setting of the first touch structure 510.
In an embodiment, in the edge region of the partition structure 200 in the second direction X, the orthographic projection of the second structure 240 in the second direction X intersects the orthographic projections of the partitioned openings 210 in the second direction X, such that the second structure 240 can carry the second touch structure 520 located between the two adjacent light-emitting structures 300 at the most edge. The second structure 240 has a large size and can accommodate a relatively large number of second touch structures 520, thus increasing the touch accuracy of the display panel 10.
In this way, by limiting the first touch structure 510 to be located above the end of the second structure 240 and limiting the first touch structure 510 to be electrically connected to the end of the second structure 240, more area is preserved for the arrangement of the second touch structures 520, ensuring a large area of the second structure 240 for accommodating the second touch structures 520, which facilitates the arrangement of the second touch structures 520.
Referring to
In an embodiment, one first ring groove 220 extends in the second direction X, facilitating the setting of the first ring groove 220, thereby making the structure of the partition structure 200 simple and stable.
In an embodiment, a plurality of first ring grooves 220 are disposed at intervals along the second direction X, thus facilitating the manufacturing of the partition structure 200 by one mask, and improving the structural accuracy and reliability of the mask.
In an embodiment, at least one first ring groove 220 extends to both edge regions of the partition structure 200 in the second direction X, so that in the second direction X, the first ring grooves 220 at the edge extend to both edge regions of the partition structure 200 in the second direction X, and the second structure 240 has a relatively large size in the second direction X.
In this way, by limiting the number of the first ring grooves 220 in the second direction X, the first ring grooves 220 are evenly provided in the partition structure 200 along the second direction X, facilitating the setting of the first ring grooves 220.
Referring to
In an embodiment, the second structures 240 are made of metal, which has a low resistance. The material of the second structures 240 may be the same as that of the touch layer 500.
In an embodiment, the second structure 240 may be made of a material selected from the group consisting of copper, silver, gold, and any combination thereof. It should be understood that the material of the second structure 240 is not limited hereto and may be other materials that meet the requirements, such as molybdenum, aluminum, cobalt, or any combination thereof.
In this way, by limiting the second structure 240 as a conductive structure and enabling the first touch structure 510 and the second structure 240 to be in contact with each other through the first via 410 in the insulating layer 400, the electrical connection between the first touch structure 510 and the second structure 240 can be conveniently achieved, which is easy to prepare and has low cost.
Referring to
In an embodiment, the display panel 10 further includes an IC. Wiring of the touch layer 500 extends to the IC through a side bezel of the display panel 10. The second structure 240 is electrically connected to the IC, and the second touch structure is electrically connected to the IC, such that the first touch structure 510 and the second touch structure 520 are controlled by the IC, respectively, thereby achieving the electrical connection between the IC and the first touch structure 510 and reducing the product thickness.
In this way, the first structure 230 provides an electrical signal for the cathode of the light-emitting structure 300, the IC provides an electrical signal for the first touch structure 510 through the second structure 240, and the IC provides an electrical signal for the second touch structure 520. In addition, the IC controls the first touch structure 510 and the second touch structure 520 to work independently, so that the touch layer 500 does not require performing time division multiplexing on the cathode signal of the light-emitting structure 300, facilitating the implementation of the touch function.
In the embodiments of the present disclosure, since the first structure 230, the second structure 240, and the second touch structure 520 are independently controlled, the independent control of the cathode of the light-emitting structure 300, the first touch structure 510, and the second touch structure 520 can be achieved. Compared to the conventional technology in which the touch layer performs time division multiplexing on the cathode signal, thereby leading to the touch function and the display function being controlled in a time-division manner through time coordination, the control logic provided in the present disclosure is relatively simple and easy to realize.
Referring to
In an embodiment, a cross-section of the side of the first structure 230 away from the first ring groove 220 along a third direction Z perpendicular to the substrate 100 may be a T-shape or an inverted trapezoidal shape, and it may also be a combination of a T-shape and an inverted trapezoidal shape.
In this way, the light-emitting layers of adjacent light-emitting structures 300 are separated by the lower end portion of the first structure 230, and the cathodes of adjacent light-emitting structures 300 are separated by the upper end portion of the first structure 230, such that although the first ring grooves 220 are provided in the partition structure 200, it can be ensured that the separation effect of the partition structure 200 on adjacent light-emitting structures 300 is not affected.
Referring to
In an embodiment, a cross-section of the second structure 240 along the third direction Z perpendicular to the substrate 100 may be a T-shape or an inverted trapezoid, and it may also be a combination of a T-shape and an inverted trapezoid.
In an embodiment, in the third direction Z perpendicular to the substrate 100, the cross-section of the second structure 240 is the same as the cross-section of the first structure 230.
In this way, both the second structure 240 and the first structure 230 have the upper end portion larger than the lower end portion, so that the first structure 230 and the second structure 240 can be formed by etching using one mask. In the etching process, the first structure 230 and the second structure 240 form an undercut structure, such that the second structure 240 and the first structure 230 are prepared by one etching process.
In an embodiment, referring to
In an embodiment, the insulating layer 400 is located on a side of the first encapsulation layer 610 away from the light-emitting structures 300, which on the one hand facilitates the setting of the insulating layer 400 and ensuring the insulating effect, on the other hand, the protection effect for the light-emitting structures 300 by the insulating layer 400 is further improved.
In this way, by providing the first encapsulation layer 610, the path for water and oxygen to enter the light-emitting structures 300 through the touch layer 500 side is cut off, which can reduce the amount of water and oxygen reaching the light-emitting structures 300, thereby improving the water and oxygen barrier capability of the display panel 10.
In an embodiment, a side of the touch layer 500 away from the insulating layer 400 is further provided with a second encapsulation layer 620 and a third encapsulation layer 630, so as to protect the touch layer 500 and further protect the light-emitting structures 300.
Referring to
At least two first touch structures 510 extend along a second direction X and are disposed at intervals. The second touch structures 520 extend along a first direction Y. Orthographic projections of the at least two first touch structures 510 disposed at intervals along the second direction X on the substrate 100 and an orthographic projection of the second structure 520 on the substrate are connected to form a straight line. The orthographic projections of the at least two first touch structures 510 on the substrate intersect with an orthographic projection of the second touch structure 520 on the substrate 100.

For example, a partition material is deposited on the substrate, and then the partition structure is etched by using one mask.
In step S300, a plurality of light-emitting structures and an insulating layer are formed on the substrate. The plurality of light-emitting structures are disposed in the partitioned openings, and the insulating layer covers a side of the partition structure away from the substrate. For example, a first conductive material layer, a light-emitting material layer, a second conductive material layer, and an insulation material layer of a whole surface may be evaporated sequentially on the whole surface, and then a plurality of first light-emitting structures and first insulating units are formed through patterning. By repeating the above manufacturing steps, the second light-emitting structures, the second insulating units, the third light-emitting structures, and the third insulating units are prepared, respectively. The first insulating units, the second insulating units, and the third insulating units constitute the insulating layer.
In step S400, a touch layer is formed on the substrate. The touch layer is disposed on a side of the insulating layer away from the partition structure. The touch layer includes a plurality of first touch structures disposed at intervals along a first direction and a plurality of second touch structures disposed at intervals along a second direction that intersects with the first direction. The first touch structures and the second touch structure are independent of each other, and the first touch structure and the second touch structure form a mutual capacitance through a bridge of the second structures. For example, a touch material is deposited on a side of the insulating layer away from the partition structure, and then the touch layer is etched by using one mask.
According to the aforementioned method for manufacturing the display panel, the partition structure is divided into the first structure and second structures by the first ring grooves, and the second structures are located in the first ring grooves. The first touch structure and the second touch structure of the touch layer that are independent of each other form a mutual capacitance through the bridge of the second structure, so that the partition structure is prepared by using one mask, and the touch layer is prepared by using one mask. The mutual capacitance between the first touch structure and the second touch structure can be realized only by using the second structures. Additionally, the touch layer is disposed on the insulating layer, so that an In-cell mutual capacitance touch control can be realized. The foregoing display panel has a relatively low manufacturing cost and is relatively thin.
