Description

Technical Field

[0001] This application relates to the field of display device technology, and in particular to a screen printing cover plate and a display device. Background Technology

[0002] In the production process of touch screens, optical adhesive is usually used to bond the cover glass and the display screen, and sealant is applied to the gap between the edge of the display screen and the cover glass to make the cover glass and the display screen bond together more tightly and improve the bonding strength between the cover glass and the display screen.

[0003] However, during the process of adhering optical adhesive to the cover glass surface, there is a problem in determining whether the adhesion position is accurate. The cover glass surface lacks clear markings indicating the adhesion position of the optical adhesive, making it difficult to visually assess its accuracy after application, and consequently, to determine the accuracy of the bonding between the display screen and the cover glass. Similarly, there are no clear markings indicating the application position of semi-solid adhesive on the cover glass surface. Utility Model Content

[0031] like Figures 1 to 3 As shown, according to a first aspect of the present invention, a screen-printed cover plate and a display device are provided, the screen-printed cover plate and the display device including a cover glass 1 and a hollow portion 3.

[0032] In the following description, reference will be made to Figure 1 and Figure 3 The specific structure of the above-mentioned components of the screen printing cover plate and display device, as well as the connection relationship of the above-mentioned components, are described in detail.

[0033] like Figure 1 and Figure 3 As shown, in this embodiment, the cover glass 1 can be a glass plate, and the first ink layer 2 can be disposed on the surface of the cover glass 1. The first ink layer 2 can be provided with a cutout portion 3. The cutout portion 3 includes a first side 31 and a second side 32. The distance between the first side 31 and the preset edge of the optical adhesive (i.e., the reference edge of the ideal adhesion position of the optical adhesive) can be a first preset distance. The distance between the second side 32 and the preset edge of the adhesive (i.e., the reference edge of the ideal adhesion position of the adhesive) is a second preset distance. In this way, the operator can determine the ideal adhesion position of the optical adhesive and the adhesive by observing the positions of the first side 31 and the second side 32 of the cutout portion 3.

[0034] Preferred, such as Figure 1 and Figure 3 As shown, in this embodiment, the cover glass 1 can be approximately rectangular in shape, giving it multiple sides. The first ink layer 2 can be printed on the outer periphery of the cover glass 1. Since optical adhesive and glue need to be adhered to multiple sides of the cover glass 1, the number of cutouts 3 can be multiple, allowing each cutout 3 to correspond one-to-one with a different side of the cover glass 1. The optical adhesive and glue can then be precisely adhered to the multiple sides of the cover glass 1 according to the positions of the first side 31 and the second side 32 of each cutout 3.

[0035] Preferred, such as Figure 1 and Figure 3 As shown, in this embodiment, the extending direction of the cutout portion 3 (referring to the overall extending direction of the cutout portion 3) can be parallel to the side of the adjacent cover glass 1. That is, a portion of the cutout portion 3 can be bent (for example, the cutout portion 3 is formed as a wave), but the overall extending direction is parallel to the side of the cover glass 1. This arrangement makes the bonding strength uniform at all positions on the side of the cover glass 1, thereby effectively improving the bonding effect between the cover glass 1 and the display screen.

[0036] Preferred, such as Figure 1 and Figure 3As shown, in this embodiment, the extending direction of the first side 31 (referring to the overall extending direction of the first side 31) and the extending direction of the second side 32 (referring to the overall extending direction of the second side 32) can be parallel to the side of the adjacent cover glass 1. This arrangement ensures that when the optical adhesive adheres with reference to the first side 31, the overall extending direction of the optical adhesive is parallel to the side of the cover glass 1, thus guaranteeing uniform bonding strength at all positions on the side of the cover glass 1. Similarly, when the adhesive adheres with reference to the second side 32, the overall extending direction of the adhesive is parallel to the side of the cover glass 1, ensuring uniform bonding strength at all positions on the side of the cover glass 1.

[0037] Furthermore, preferably, such as Figure 1 and Figure 3 As shown, in the embodiment, the first side 31 can be parallel to the second side 32, so that the distance between the first side 31 and the second side 32 is equal everywhere, thereby further ensuring that the bonding strength of the cover glass 1 is uniform at each position.

[0038] Preferred, such as Figure 1 and Figure 3 As shown, in this embodiment, the second side 32 can be located outside the first side 31 (i.e., the side away from the center of the cover glass 1), so that the adhesion position of the optical adhesive is located inside the adhesive, corresponding to the bonding process between the cover glass 1 and the display screen. More preferably, the preset edge of the optical adhesive can be the outer edge 4 of the optical adhesive, so that the adhesion position of the optical adhesive is located between the cutout portion 3 and the inner edge 20 of the first ink layer. The preset edge of the adhesive can be the outer edge of the adhesive, so that after the adhesive adheres to the cover glass 1, it can be contained in the groove formed by the cutout portion 3, that is, the adhesive is applied between the first side 31 and the second side 32. Since the adhesive (sealing adhesive) is in a liquid state when it is not fully cured, it has a certain degree of fluidity. The cutout portion 3 can limit the flow range of the adhesive and make the dispensing area visible.

[0039] However, this is not the only option. Using the outer edge 4 of the optical adhesive and the outer edge of the glue as the preset edges is only a preferred embodiment. In actual production, other edges of the optical adhesive and glue can also be selected as preset edges according to actual needs, so that operators can easily determine the ideal adhesion position of the optical adhesive and glue.

[0040] Preferred, such as Figure 1As shown, in the first embodiment, the cutout portion 3 can be formed as a straight strip structure. The distance between the first side 31 and the preset edge of the optical adhesive (i.e., the outer edge 4 of the optical adhesive) (i.e., the first preset distance) is 0 mm, so that the first side 31 coincides with the preset edge of the optical adhesive. This setting allows the operator to intuitively determine the ideal adhesion position of the optical adhesive. Similarly, the distance between the second side 32 and the preset edge of the adhesive (i.e., the outer edge of the adhesive) (i.e., the second preset distance) is 0 mm, so that the second side 32 coincides with the preset edge of the adhesive, making it easy for the operator to intuitively determine the ideal adhesion position of the adhesive.

[0041] However, this is not the only limitation. Setting the first preset distance to 0mm is merely a preferred embodiment. As long as the adhesion position of the optical adhesive can be easily determined, the first preset distance can be set to other dimensions. Since the adhesive is fluid, the perforated portion 3 is needed to limit the flow range of the adhesive; therefore, the second preset distance can be 0mm.

[0042] Specifically, such as Figure 2 As shown, in the second embodiment, the cutout portion 3 can be formed as a straight strip structure. The distance between the first side 31 and the preset edge of the optical adhesive is 2mm (i.e., the first side 31 is 2mm inward compared to the first embodiment), so that the preset edge of the optical adhesive can be exposed on the first side 31 of the cutout portion 3. This setting allows the optical adhesive to adhere to the gradient structure at the edge of the cutout portion 3, further improving the adhesion between the cover glass 1 and the optical adhesive. The distance between the second side 32 and the preset edge of the adhesive can be 0mm, so that the second side 32 coincides with the preset edge of the adhesive, making it easy for the operator to intuitively determine the ideal adhesion position of the adhesive.

[0043] Furthermore, preferably, in the embodiment, the first preset distance can be 0mm-0.2mm. This setting can improve the adhesion between the cover glass 1 and the optical adhesive, while avoiding an excessively large first preset distance that would make it difficult for operators to intuitively determine the ideal adhesion position of the optical adhesive.

[0044] Preferably, the hollowed-out portion 3 may also include several partition portions 5. The partition portions 5 divide the hollowed-out portion 3 into multiple segments, and the adhesive is applied to the areas formed by these partitions. Specifically, for example... Figure 2 As shown, in the second embodiment, the partition 5 can divide the hollow portion 3 into multiple segments along its length. The partition 5 can be formed as a strip and extend along the width direction of the hollow portion 3 to divide the hollow portion 3. Preferably, there can be multiple partitions 5, so that the hollow portion 3 can be divided into multiple areas with appropriate spacing.

[0045] Furthermore, preferably, such as Figure 2 As shown, in the second embodiment, the dimension of the partition portion 5 in the extending direction of the hollow portion 3 can be 0.5 mm, that is, the distance between two adjacent areas of the hollow portion 3 is 0.5 mm, so as to prevent the glue from flowing between two adjacent areas of the hollow portion 3. The dimension of the area formed by the partition of the hollow portion 3 in the extending direction of the hollow portion 3 can be 10 mm, which can better restrict the flow of glue.

[0046] Furthermore, preferably, the outline of the hollowed-out portion 3 can be formed into a zigzag pattern. Specifically, such as... Figure 3 As shown, in the third embodiment, the first side 31 can be formed with a plurality of recessed areas 6 at intervals, so that one side of the cutout portion 3 is formed into a serrated structure. The recessed areas 6 can be recessed away from the second side 32. The shape of the recessed areas 6 can be rectangular. Further, preferably, the dimension of the recessed areas 6 in the direction parallel to the extension of the cutout portion 3 can be 1 mm (i.e., the length of the recessed areas 6 is 1 mm), and the dimension of the recessed areas 6 in the direction perpendicular to the extension of the cutout portion 3 can be 0.5 mm (i.e., the width of the recessed areas 6 is 0.5 mm). In this case, the distance between the preset edge of the optical adhesive and the inner side of the recessed area 6 (i.e., the side near the center of the cover glass 1) is a first preset distance. Preferably, the first preset distance can be 0.2 mm. This setting allows the optical adhesive to adhere to the serrated gradient structure at the edge of the cutout portion 3, thereby greatly improving the adhesion between the cover glass 1 and the optical adhesive. At the same time, the serrated structure can also effectively restrict the flow of adhesive to prevent adhesive from flowing out of the cutout portion 3.

[0047] Preferred, such as Figures 1 to 3 As shown, in this embodiment, the screen-printed cover plate may further include a second ink layer 9. During processing, the second ink layer 9 is first screen-printed on the surface of the cover glass 1, and then a first ink layer 2 with a cutout portion 3 is screen-printed on the second ink layer 9. This allows the second ink layer 9 to cover the surface of the cover glass 1, and the first ink layer 2 to cover the surface of the second ink layer 9. In this case, the second ink layer 9 can be exposed through the cutout portion 3 to the first ink layer 2, making it easier for operators to visually identify the first side 31 and the second side 32. Further, preferably, the thickness of the first ink layer 2 can be 6 μm to 10 μm, and the thickness of the second ink layer 9 can be 4 μm to 10 μm.

[0048] In addition, such as Figures 1 to 3 As shown, according to a second aspect of the present invention, a display device is provided, the display device including the screen-printed cover plate as described above. Specifically, the display device is a device having a display screen, such as a tablet computer.

[0049] During use, the first ink layer 2 has a perforated portion 3. By observing the positions of the first side 31 and the second side 32 of the perforated portion 3, the operator can determine the ideal adhesion position of the optical adhesive and the glue, as well as whether the adhesive is correctly placed. At the same time, the perforated portion 3 can effectively limit the flow range of the glue and make the dispensing area visible, making it easier for the operator to dispense the glue.
