[0035] This application provides a screen processing method that is convenient for tearing off the heavy release film. For details, please refer to Figure 1 , Figure 1 This is a flow chart of an embodiment of a screen processing method for conveniently removing a heavy release film in this application. Figure 1 As shown, the screen body processing method includes:

[0036] Step S11: providing a screen body to be cut.

[0037] The screen body to be cut includes the screen body, the screen body boundary and the area to be cut outside the screen body boundary. The screen body boundary is also called a cutting line. When cutting, cutting is performed along the cutting line to obtain the screen body.

[0038] Step S12: performing a first cutting on the screen body boundary at the preset position of the screen body to be cut, so as to reserve a tearing hand position at the preset position.

[0039] In this step, the tear finger position refers to the blank position after the screen body to be cut is cut off, so as to facilitate the subsequent lamination of the heavy release film to form a tear finger at this position.

[0040] Step S13: applying adhesive material to the surface of the screen to be cut.

[0041] The surface of the adhesive material includes a heavy release film to be torn off. Specifically, the adhesive material includes an OCA colloid attached to the surface of the screen to be cut, and a heavy release film attached to the surface of the colloid away from the screen to be cut. The heavy release film and the light release film both have one side that is sticky, and the difference lies in the amount of force used when tearing them off.

[0042] Step S14: performing a second cutting on the screen body boundary at other positions of the screen body to be cut except the preset position, and retaining the heavy release film at the preset position, so that the heavy release film forms a tear handle at the preset position.

[0043] The screen boundary of the screen body to be cut by the second cutting at least overlaps with the screen boundary of the screen body to be cut by the first cutting. For example, the screen boundary of the screen body to be cut includes four cutting edges. The first cutting edge can be cut by the first cutting edge, and the second cutting edge can be cut by the second cutting edge, thereby realizing the cutting of the screen body to be cut. The second cutting edge can also be further cut by the first cutting edge, which is not limited here.

[0044] In a further embodiment, in order to avoid cutting residues of the screen to be cut, in addition to cutting the screen border at other positions except the preset position, the screen border at the preset position may be repeatedly cut, which is not limited here.

[0045] After step S14, the method further includes: tearing off the heavy release film by taking the heavy release film at the preset position as a tearing starting point.

[0046] Among them, after the second cutting, the uncut heavy release film will remain at the preset position, so that it is convenient to use the heavy release film here as the force point for tearing off. The heavy release film remaining at this position can be called a tearing handle. The tearing starting point refers to the junction between the heavy release film and the screen body at the preset position, which is also the main force point when tearing off the heavy release film.

[0047] In this embodiment, two cuts are made before and after the film is applied to achieve complete cutting of the screen boundary. At the same time, the screen to be cut is pre-cut before the film is applied to reserve a tearing hand position. After the film is applied, the screen to be cut is cut for the second time, and the film layer at the tearing hand position is not cut, so that the film layer at the tearing hand position is retained to form a tearing hand. The existence of the tearing hand can increase the distance between the film peeling point and the screen body, increase the film peeling angle and facilitate the fulcrum to be obtained, thereby reducing the difficulty of peeling off the heavy release film.

[0048] The colloid is OCA glue. In a preferred embodiment, the boundary of the colloid at least at the tearing position is smaller than the boundary of the heavy release film, so as to facilitate the separation of the colloid and the heavy release film. The colloid is a double-sided adhesive, the colloid is adhered to the surface of the screen body, and the heavy release film is adhered to the surface of the colloid. After cutting, the colloid is adhered to the surface of the screen body, and the heavy release film is torn off to separate the colloid from the heavy release film, and the screen body has adhesion.

[0049] Furthermore, the boundary of the colloid at the tearing position is not larger than the boundary of the screen body. Specifically, the colloid may be slightly smaller than the boundary of the screen body, or may coincide with the boundary of the screen body. By making the boundary of the colloid not larger than the boundary of the screen body, after tearing off the heavy release film, the colloid does not need to be processed again to avoid the colloid protruding from the boundary of the screen body.

[0050] In a specific embodiment, the screen body boundary includes a straight cutting edge and an arc cutting edge. Figure 2 , Figure 2 This is a schematic diagram of the structure of the first embodiment of the screen body to be cut in this application. Figure 2 As shown, the screen body 100 to be cut includes a screen body boundary 11, and the screen body boundary 11 includes a straight cutting edge 110 and an arc cutting edge 120 located at the intersection of two adjacent straight cutting edges 110. Preferably, the arc cutting edge 120 is a 90-degree arc edge, that is, two adjacent straight cutting edges are vertically arranged, which is not limited here.

[0051] Furthermore, the screen body boundary 11 at least includes a first straight cutting edge 111 and a second straight cutting edge 112 and a third straight cutting edge 113 located at opposite ends of the first straight cutting edge 111. Figure 3 , Figure 3 This is a schematic diagram of the structure of the second embodiment of the screen body to be cut in this application. Figure 3As shown, the screen body boundary 11 includes a first linear cutting edge 111, a second linear cutting edge 112 and a third linear cutting edge 113, and the second linear cutting edge 112 and the third linear cutting edge 113 are respectively arranged adjacent to the first linear cutting edge 111. The intersection position of the first linear cutting edge 111 and the second linear cutting edge 112 and the third linear cutting edge 113 includes an arc-shaped cutting edge. Preferably, the length L1 of the first linear cutting edge 111 is shorter than the spacing L between the second linear cutting edge 112 and the third linear cutting edge 113, so as to facilitate the formation of a reserved position at the intersection between the first linear cutting edge 111 and the second linear cutting edge 112 and / or between the first linear cutting edge 111 and the third linear cutting edge 113, as shown in FIG. Figure 3 In the dotted box.

[0052] Furthermore, a preset position can be formed in the gap between the first straight cutting edge 111 and the second straight cutting edge 112, or in the gap between the first straight cutting edge 111 and the third straight cutting edge 113, or in the gaps on both sides of the first straight cutting edge 111, which is not limited here.

[0053] In a specific embodiment, before step S12, the method further includes: linearly cutting the screen body to be cut along the first linear cutting edge to expose the first linear cutting edge.

[0054] The first straight cutting edge is the boundary of the binding area of ​​the display screen. Figure 4 , Figure 4 This is a schematic diagram of the structure of an embodiment of the first cutting step of the screen body to be cut in this application. Figure 4 As shown, the screen to be cut is linearly cut along the first linear cutting edge to remove the redundant portion of the lower frame of the screen to be cut.

[0055] In a specific embodiment, step S12 specifically includes: performing a first cut from the first straight cutting edge along the screen boundary to the second straight cutting edge and / or the third straight cutting edge, so as to reserve a tearing position at the junction of the first straight cutting edge and the second straight cutting edge and / or the junction of the first straight cutting edge and the third straight cutting edge and at the position of the second straight cutting edge and / or the third straight cutting edge close to the first straight cutting edge. Among them, this step specifically includes: performing a first cut from the first straight cutting edge along the screen body boundary to the second straight cutting edge, so as to reserve a tearing hand position at the junction of the first straight cutting edge and the second straight cutting edge and at the position of the second straight cutting edge close to the first straight cutting edge after the second cutting; or, performing a first cut from the first straight cutting edge along the screen body boundary to the third straight cutting edge, so as to reserve a tearing hand position at the junction of the first straight cutting edge and the third straight cutting edge and at the position of the third straight cutting edge close to the first straight cutting edge after the second cutting; or, performing a first cut from the first straight cutting edge along the screen body boundary in the direction of the second straight cutting edge and the third straight cutting edge respectively, including cutting the junction of the first straight cutting edge and the second straight cutting edge and the junction of the first straight cutting edge and the third straight cutting edge, and cutting parts of the second straight cutting edge and the third straight cutting edge, so as to reserve a tearing hand position at the junction of the first straight cutting edge with the second straight cutting edge and the third straight cutting edge respectively, and at the positions of the second straight cutting edge and the third straight cutting edge close to the first straight cutting edge.

[0056] For more details, please refer to Figure 5 , Figure 5 This is a schematic diagram of the structure of the first embodiment of the second cutting step of the screen body to be cut in this application. Figure 5 As shown, cutting is performed from the first straight cutting edge 111 along the screen boundary toward the second straight cutting edge 112 and the third straight cutting edge 113. This step includes cutting the junction between the first straight cutting edge 111 and the second straight cutting edge 112 and the junction between the first straight cutting edge 111 and the third straight cutting edge 113, and cutting the second straight cutting edge 112 and the third straight cutting edge 113 near the first straight cutting edge 111. The junction between the first straight cutting edge 111 and the second straight cutting edge 112 includes an arc cutting edge and / or a straight cutting edge.

[0057] In another specific embodiment, step S12 includes: cutting from the first straight cutting edge 111 to the second straight cutting edge 112 and / or from the first straight cutting edge 111 to the arc junction of the third straight cutting edge 113, and cutting until it is aligned with the arc junction. Figure 6 , Figure 6 This is a schematic diagram of the structure of the second embodiment of the second cutting step of the screen body to be cut in this application. Figure 6 As shown, the cutting is performed from both sides of the first straight cutting edge 111 in the direction of the arcuate cutting edge 120 close to the second straight cutting edge 112 and / or the third straight cutting edge 113, and the cutting is performed until it is flush with the cutting edge of the arcuate cutting edge 120. In this embodiment, preferably, the intersection of the first straight cutting edge 111 and the second straight cutting edge 112 and the third straight cutting edge 113 includes the arcuate cutting edge 120. The cutting is performed from the first straight cutting edge 111 along the straight cutting edge in the direction of the arcuate cutting edge close to the second straight cutting edge 112 and the third straight cutting edge 113.

[0058] In the first specific embodiment, step S14 specifically includes: performing a second cutting along the second straight cutting edge and / or the third straight cutting edge in a direction close to the first straight cutting edge, and retaining the heavy release film on the arcuate cutting edge at the junction of the first straight cutting edge and the second straight cutting edge and / or the arcuate cutting edge at the junction of the first straight cutting edge and the third straight cutting edge after the first cutting, and the tearing hand is the heavy release film on the arcuate cutting edge between the first straight cutting edge and the second straight cutting edge and / or the heavy release film on the arcuate cutting edge between the first straight cutting edge and the third straight cutting edge.

[0059] Further preferably, the second cutting also includes a portion of the second linear cutting edge and / or the heavy release film on the third linear cutting edge. Specifically, it may include a portion of the linear boundary position of the second linear cutting edge close to the first linear cutting edge, and / or a portion of the linear boundary position of the third linear cutting edge close to the first linear cutting edge.

[0060] For more details, please refer to Figure 7 , Figure 7 This is a schematic diagram of the structure of the first embodiment of the third cutting step of the screen body to be cut in this application. Figure 7 As shown, the screen is cut along the screen boundary 11, and the heavy release film attached in step S13 is retained at the tearing position of the first cut, that is, the tearing position of the first cut is not cut repeatedly, so that the heavy release film forms a tearing hand 200 at the tearing hand position. The second cutting is to cut the remaining screen boundary after the first cutting.

[0061] Specifically, the first linear cutting edge 111 is shorter than the spacing between the second linear cutting edge 112 and the third linear cutting edge 113. The junction between the first linear cutting edge 111 and the second linear cutting edge 112 and / or the third linear cutting edge 113 also includes a first linear junction edge 1111, a second linear junction edge 1112 and an arc junction edge 1120, and the first linear cutting edge 111 is sequentially connected to the second linear cutting edge 112 and / or the third linear cutting edge 113 through the first linear junction edge 1111, the second linear junction edge 1112 and the arc junction edge 1120. The first linear junction edge 1111 is perpendicular to the first linear cutting edge 111 and extends toward the second linear cutting edge 112 and the third linear cutting edge 113. The second straight boundary edge 1112 is connected to an end of the first straight boundary edge 1111 away from the first straight cutting edge 111 and is arranged in parallel with the first straight cutting edge 111, that is, it is arranged in parallel and not in a colinear relationship with the first straight cutting edge 111. The arc boundary edge 1120 is also an arc cutting edge 120 of the screen body boundary 11, and is located between the second straight boundary edge 1112 and the second straight cutting edge 112 and / or the third straight cutting edge 113.

[0062] In a further embodiment, the second cutting can also partially repeat the cutting of the tearing finger position reserved for the first cutting. Step S14 specifically also includes: cutting the arcuate cutting edge at the intersection of the second straight line cutting edge and the first straight line cutting edge and / or the arcuate cutting edge at the intersection of the third straight line cutting edge and the first straight line cutting edge of the screen body to be cut for the second time, and retaining the heavy release film (tear finger 200) on the first straight line intersection edge 1111 and the second straight line intersection edge 1112 at the intersection of the first straight line cutting edge 111 and the second straight line cutting edge 112, and / or the heavy release film (tear finger 200) on the first straight line intersection edge 1111 and the second straight line intersection edge 1112 at the intersection of the first straight line cutting edge 111 and the third straight line cutting edge 113. For details, please refer to Figure 8 , Figure 8 This is a structural schematic diagram of the second embodiment of the third cutting step of the screen body to be cut in this application. Figure 8 As shown in the middle right figure, the arcuate cutting edge 1120 at the intersection of the second straight cutting edge 112 and the first straight cutting edge 111 at the reserved tearing hand position in step S12 is repeatedly cut, and the tearing hand 200 on the straight intersection edge of the first straight cutting edge 111 close to the intersection of the second straight cutting edge 112 is retained; and / or the arcuate cutting edge 120 of the third straight cutting edge 113 and the first straight cutting edge 111 is repeatedly cut, and the tearing hand 200 on the straight intersection edge of the first straight cutting edge 111 close to the intersection of the third straight cutting edge 113 is retained. Among them, the straight intersection edge includes the first straight intersection edge 1111 and the second straight intersection edge 1112. It should be noted that the tearing hand 200 can be one, two or a whole edge.

[0063] In the second specific embodiment, step S12 includes: cutting from the first straight cutting edge 111 to the arc junction edge (also the arc cutting edge of the screen body boundary) of the second straight cutting edge 112 and / or the third straight cutting edge 113, and cutting until the tangent plane of the arc junction edge is aligned. Step S14 includes: performing a second cutting on the arc junction edge 1120 at the junction of the second straight cutting edge 112 and the first straight cutting edge 111 of the screen body to be cut, and part of the second straight junction edge 1112, and / or performing a second cutting on the arc junction edge 1120 at the junction of the third straight cutting edge 113 and the first straight cutting edge 112, and part of the second straight junction edge 1112, and retaining the heavy release film on the second straight junction edge 1112 at the position of the first straight cutting edge 111 close to the second straight cutting edge 112 and / or retaining the heavy release film on the second straight junction edge 1112 at the position of the first straight cutting edge 111 close to the third straight cutting edge 113. For details, please refer to further. Fig. 9 , Fig. 9 This is a schematic diagram of the structure of the third embodiment of the third cutting step of the screen body to be cut in this application. Fig. 9 As shown, in this embodiment, preferably, the intersection edges of the first straight line cutting edge 111, the second straight line cutting edge 112 and the third straight line cutting edge 113 include a first straight line intersection edge 1111, a second straight line intersection edge 1112 and an arc intersection edge 1120; wherein the straight line intersection edge 1110 is arranged close to the first straight line cutting edge 111, and the arc intersection edge 1120 is arranged close to the second straight line cutting edge 112 and / or the third straight line cutting edge 113. Step S14 includes: performing a second cutting on the arc junction edge 1120 between the second straight line cutting edge 112 and the first straight line cutting edge 111 and / or the arc junction edge 1120 between the third straight line cutting edge 113 and the first straight line cutting edge 111 of the screen body to be cut, and retaining the heavy release film at the position of the first straight line junction edge 1111 and the second straight line junction edge 1112 of the first straight line cutting edge 111 close to the second straight line cutting edge 112 and / or close to the third straight line cutting edge 113, so as to form a tearing hand 200.

[0064] In this embodiment, preferably, the arc-shaped cutting edge or the arc-shaped boundary edge of the screen body to be cut is repeatedly cut. This can reduce the contact area between the starting point of the heavy release film and the screen body, and concentrate the starting points on the lower side of the screen body (that is, the side of the first cutting edge). This can minimize the thermal impact of the cutting on the colloid body and avoid problems such as tearing off the heavy film and pulling the glue as much as possible.

[0065] In the above embodiment, it is further preferred that the boundary of the colloid at the arc-shaped cutting edge 120 is smaller than the boundary of the screen body. Fig.10 , Fig.10This is a partial enlarged schematic diagram of an embodiment of the screen body to be cut in this application. Fig.10 As shown, the boundary of the colloid boundary 20 at the arc-shaped cutting edge position is smaller than the screen body boundary 11. Preferably, the colloid boundary 20 adopts an inward-retracted design at least at the arc-shaped intersection edge position corresponding to the tearing hand position. Further, the colloid adopts an inward-retracted screen body design at the four corners of the screen body (that is, the four arc-shaped cutting edges), which is inwardly retracted by about 0.2 to 0.3 mm, specifically, 0.2 mm, 0.22 mm, 0.24 mm, 0.26 mm, 0.28 mm, and 0.3 mm, so that the heat-affected zone has little effect on the colloid during cutting, avoiding the adhesion of the colloid body to the heavy release film, resulting in tearing the heavy release film and pulling the glue or stripping.

[0066] It should be noted that the arc-shaped boundary edge 1120 is also called an arc-shaped cutting edge 120 .

[0067] In this embodiment, the boundary of the colloid 20 does not exceed the boundary of the heavy release film 30, nor does it exceed the boundary of the screen body 100 to be cut. Preferably, the boundary of the colloid 20 does not exceed the screen body boundary 11 at least at a preset position.

[0068] The present application also provides a display screen, wherein the display screen is manufactured by using the screen processing method described in any of the above embodiments. Fig.11 , Fig.11 This is a schematic diagram of the structure of an embodiment of the display screen of the present application. Fig.11 As shown, the display screen includes a screen body 10 and a colloid 20 arranged on the surface of the screen body 10. A bending area 101 (or a pin area) is arranged at the lower frame of the screen body 10. Preferably, during the manufacturing process, the tearing handle can be arranged at a position close to the bending area 101. In other embodiments, the tearing handle can also be arranged at other arc-shaped intersection positions of the screen body 10, which is not limited here. The colloid 20 can cover the surface of the bending area 101, or it can not cover the surface of the bending area 101, which is not limited here.

[0069] The beneficial effect of the present application is that the screen body is cut twice, the first cutting is to cut out the tearing hand position, the second cutting is to cut along the screen body boundary, and the heavy film at the tearing hand position is retained, thereby forming a tearing hand for tearing off the heavy film, reducing the difficulty of tearing off the heavy film, and effectively avoiding film tearing, glue pulling and film throwing downtime. Furthermore, the colloid adopts an inward angle design at the film removal position, which increases the distance between the cutting line and the colloid and reduces the thermal impact of the cutting process on the colloid.

[0070] The above are merely embodiments of the present application and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
