[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.
[0029] Please refer to Figures 1 to 5 As shown, in an embodiment of the utility model, a substrate is provided for being attached to a light-emitting surface of a display module, a functional layer 2 and a glue dispensing structure 5 are provided between the substrate and the light-emitting surface, the substrate comprises a board body 1 and a first identification structure 3, the first identification structure 3 is provided on the board body 1, the surface of the board body 1 has a first area 11, the first area 11 is an area reserved for contact with the functional layer 2, the first identification structure 3 is at least partially located in the first area 11 to indicate whether the attachment position of the functional layer 2 is located in the first area 11.
[0030] Specifically, the board body 1 refers to a thin plate-like component that allows light to pass through. The board body 1 is generally made of glass, and the board body 1 can also be made of plastic and other materials. The functional layer 2 refers to a film-like structure attached to the surface of the substrate. The functional layer 2 may include but is not limited to a film sensor layer, an OCA (Optically Clear Adhesive) layer, etc., and the functional layer 2 may include one or more of the film sensor layer, the OCA layer, etc. In the touch screen production process, the functional layer 2 is generally attached to the surface of the board body 1 to form a substrate assembly, and then the substrate assembly is installed on the light-emitting surface of the display module.
[0031] The glue dispensing structure 5 is a collection of glue formed on the board body 1 through a glue dispensing operation.
[0032] The first area 11 is a virtual area on the surface of the board body 1. The first area 11 represents the qualified range of the functional layer 2 after being attached to the board body 1, and is not a real structure. The first area 11 includes the theoretical attachment area of the functional layer 2 and the deviation range area allowed for the edge of the functional layer 2. And each functional layer 2 corresponds to a single first area 11, and multiple first areas 11 may overlap with each other. During production, if the functional layer 2 is in accordance with the first area 11 after being attached, it means that the product is qualified; if the functional layer 2 partially exceeds the first area 11 after being attached, it means that the product is unqualified. The first identification structure 3 refers to an identification structure that can be observed by the naked eye on the board body 1. The first identification structure 3 can be a convex structure or a groove structure protruding from the surface of the board body 1. The first identification structure 3 can also be an opaque structure arranged on the board body 1, such as an ink coating or a coating structure of other colors. The first identification structure 3 can also be formed by leaving a part in a coating area. The first identification structure 3 as a whole can be an integral graphic, such as a frame shape that matches the shape of the functional layer 2; at the same time, the first identification structure 3 can also be composed of multiple independent parts that are spaced apart from each other. After production is completed, the first identification structure 3 can be removed from the board body 1, or the first identification structure 3 can be left on the board body 1.
[0033] The substrate provided by the embodiment of the utility model is provided with a first identification structure 3 on the board body 1, and the first identification structure 3 is used as a reference for detecting whether the functional layer 2 is located within the first area 11. Compared with the prior art, after the functional layer 2 is attached, the relative position of the edge of the functional layer 2 and the first identification structure 3 can be directly compared by visual inspection, so as to determine whether the functional layer 2 is consistent with the range of the first area 11, thereby quickly detecting whether the attachment position of the functional layer 2 is accurate, avoiding defective products from flowing into the subsequent order or being shipped to customers, and improving product quality and production efficiency.
[0034] In one embodiment, see Figure 1 and Figure 2 , the first area 11 is formed by connecting a plurality of edge lines end to end, the first identification structure 3 includes a plurality of first identification parts 31, the first identification part 31 is divided into a plurality of groups, each group includes a plurality of first identification parts 31, a plurality of groups of first identification parts 31 correspond to at least two edge lines, and a plurality of first identification parts 31 in the same group are arranged at intervals along the corresponding edge lines. Specifically, an edge line refers to a line structure with a certain length, a plurality of edge lines are first connected to form a polygonal area that matches the shape of the functional layer 2, and the polygon is generally a rectangular ring. The first identification part 31 refers to a part of the first identification structure 3, that is, the first identification structure 3 refers to a whole composed of a plurality of first identification parts 31. And the first identification part 31 is divided into a plurality of groups, and a plurality of groups of first identification parts 31 are arranged corresponding to at least two edge lines. The edge line is generally two edge lines arranged opposite to each other and at least one edge line located at both edge lines connected. The entire first identification structure 3 is composed of multiple first identification parts 31, and the first identification part 31 is divided into multiple groups. The multiple groups of first identification structures 3 are arranged corresponding to at least two edge lines, and multiple first identification structures 3 in the same group are arranged at intervals along the corresponding edge lines, so that multiple edges of the functional layer 2 can be detected, thereby improving the accuracy of detecting the fitting position of the functional layer 2.
[0035] In one embodiment, see Figure 1 , there are multiple functional layers 2, and the sizes of the multiple functional layers 2 are different, and each functional layer 2 corresponds to a first identification structure 3. Specifically, there are multiple functional layers 2. The functional layer 2 may include a film sensor layer, an OCA layer, etc., and each functional layer 2 is arranged corresponding to a first identification structure 3, so that when there are multiple functional layers 2, it is still possible to conveniently and quickly detect whether the functional layer 2 is accurately attached, thereby improving production efficiency.
[0036] In one embodiment, see Figure 3 and Figure 4The first identification portion 31 includes a first boundary 311, a second boundary 312 and a center position 313. The first boundary 311 is located at the edge line, the second boundary 312 is located in the first area 11, and the center position 313 is set between the first boundary 311 and the second boundary 312. Specifically, the center position 313 represents the theoretical position of the edge of the functional layer 2 on the board body 1, the first boundary 311 represents the maximum value of the edge of the functional layer 2 on one side of the center position 313, and the second boundary 312 represents the maximum value of the edge of the functional layer 2 on the other side of the center position 313. After the functional layer 2 is attached to the board body 1, when the edge of the functional layer 2 is located in the area between the first boundary 311 and the second boundary 312, it means that the edge position of the functional layer 2 meets the tolerance requirements of the qualified product. In addition, the first identification portion 31 has a center position 313, which is convenient for the bonding equipment to adjust the position according to the position of the center position 313.
[0037] In an alternative embodiment, see Figure 1 The position of the first boundary 311 may coincide with the edge line position of the first region 11, and the second boundary 312 may be located inside the first region 11. During detection, in addition to detecting whether the edge of the functional layer 2 exceeds the range of the first region 11 through the first boundary 311, the minimum position of the edge of the functional layer 2 may also be detected through the second boundary 312, so that the position detection accuracy of the functional layer 2 is improved, thereby improving the quality of the product.
[0038] In a specific embodiment, see Figure 4 The first boundary 311 and the second boundary 312 are both strip-shaped portions, and the first identification portion 31 also includes two central strip-shaped portions, both of which are located between the first boundary 311 and the second boundary 312 and connected to the two strip-shaped portions, the two central strip-shaped portions are cross-arranged, and the intersection of the two central strip-shaped portions is the center position 313. Specifically, the strip-shaped portion and the central strip-shaped portion both refer to a strip-shaped structure with a certain length, and the two strip-shaped portions are spaced apart from each other and arranged in parallel. Two central strip-shaped portions are cross-arranged in the area between the two strip-shaped portions, which can conveniently and clearly mark the positions of the first boundary 311 and the second boundary 312, and the position of the center position 313 is cross-marked by the two central strip-shaped portions, so that the structure of the first identification portion 31 is simpler and the production is more convenient.
[0039] In one embodiment, see Figure 1 and Figure 2, the surface of the board body 1 also has a second area 12, the second area 12 is a reserved area for contacting with the glue dispensing structure 5, a second identification structure 4 is provided on the board body 1, and the second identification structure 4 is at least partially located in the second area 12 to indicate whether the location of the glue dispensing structure 5 is located within the range of the second area 12. Specifically, the second area 12 refers to a virtual area on the surface of the board body 1, and the second area 12 represents the qualified range after the glue dispensing structure 5 is attached to the board body 1. There can be multiple second areas 12, and multiple second areas 12 can be arranged along the circumferential direction of the board body 1, and each second area 12 is arranged corresponding to a second identification structure 4. Specifically, the second identification structure 4 refers to an identification structure that can be observed by the naked eye on the board body 1, and the second identification structure 4 can be a convex structure or a groove structure protruding from the surface of the board body 1. The second identification structure 4 can also be an opaque structure provided on the board body 1, such as an ink coating or a coating structure of other colors. The second identification structure 4 can also be formed by leaving a portion in a coating area. The second identification structure 4 can be an integral graphic, such as a frame shape that matches the shape of the second area 12; at the same time, the second identification structure 4 can also be composed of multiple independent parts that are spaced apart from each other. After production is completed, the second identification structure 4 can be removed from the board body 1 or left on the board body 1. The second identification structure 4 can intuitively indicate the size of the second area 12 on the board body 1, so that after the dispensing is completed, it can be visually judged whether the dispensing structure 5 is consistent with the second area 12, thereby improving the detection speed of the position accuracy and size accuracy of the dispensing structure 5.
[0040] In one embodiment, see Figure 5 The second identification structure 4 includes two second identification parts 41, which are respectively located at two positioning ends of the second area 12, and the positioning ends are the two ends of the second area 12 along its own length direction, and each second identification part 41 has a third boundary 411 and a fourth boundary 412 spaced from the third boundary 411, and the distance between the fourth boundary 412 and the third boundary 411 matches the width of the second area 12. Specifically, the second identification structure 4 includes two second identification parts 41, and the length accuracy of the second area 12 corresponding to it can be indicated by the distance between the two second identification parts 41; at the same time, the width accuracy of the second area 12 can be indicated by the width between the third boundary 411 and the fourth boundary 412 on a second identification part 41. In this embodiment, the length accuracy of the second area 12 is indicated by two spaced second identification parts 41, and the width accuracy of the second area 12 is indicated by the width between the fourth boundary 412 and the third boundary 411 in the second identification part 41, so that the indication effect of the second identification structure 4 is more intuitive and clear, and the detection of the dispensing structure 5 is more precise and accurate.
[0041] In one embodiment, see Figure 5 , the third boundary 411 is also a strip-shaped portion, and the second identification structure 4 also includes two inclined strip-shaped portions of equal length, the strip-shaped portion and the two inclined strip-shaped portions are arranged to form an isosceles triangle, and the intersection of the two inclined strip-shaped portions is the fourth boundary 412. Specifically, the strip-shaped portion and the inclined strip-shaped portion both refer to a strip-shaped structure with a certain length, and by arranging the strip-shaped portion and the two inclined strip-shaped portions to form an isosceles triangle, the third boundary 411 and the fourth boundary 412 on the second identification portion 41 can be conveniently marked, and at the same time, the structure of the second identification portion 41 is simpler and the manufacturing is more convenient.
[0042] In an alternative embodiment, see Figure 3 When the number of functional layers 2 is two, each functional layer 2 corresponds to a first identification structure 3, and the number of first identification structures 3 is also two. At this time, the first identification parts 31 in the two first identification structures 3 can be arranged at intervals along a direction perpendicular to the edge of the functional layer 2, and the second identification part 41 can be arranged between the two first identification parts 31, so that the first identification part 31 and the second identification part 41 can be integrated in a smaller range, which can reduce the area occupied by the two and facilitate the production of the first identification structure 3 and the second identification structure 4.
[0043] In one embodiment, see Figure 2 , the first identification structure 3 and the second identification structure 4 are both printed on the surface of the board body 1 by screen printing. Specifically, screen printing refers to the process of printing patterns, text or symbols on an object. Among them, the first identification structure 3 and the second identification structure 4 can be formed by hollowing out a local area when printing a protective ink layer on the board body 1 by screen printing; or the first identification structure 3 and the second identification structure 4 can be directly printed on the board body 1 by screen printing, which can make the production of the first identification structure 3 and the second identification structure 4 more convenient, and also reduce the overall production cost of the substrate.
[0044] Second, see Figure 2 , a substrate assembly is provided, comprising a functional layer 2, a dispensing structure 5 and any of the above substrates, wherein the functional layer 2 can be directly or indirectly attached to the substrate, and when there are multiple functional layers 2, one of the functional layers 2 can be attached to the substrate, and the other functional layers 2 can be attached to the adjacent functional layers 2 in sequence. At the same time, the dispensing structure 5 can be directly attached to the substrate; the dispensing structure 5 can also be attached to the functional layer 2. It can be understood that the beneficial effects of the above second aspect can refer to the relevant description of the above first aspect, and will not be repeated here.
