Description

Promote abnormal detection effect's of bonding display module assembly structure Technical Field The utility model relates to the technical field of display modules, in particular to a display module structure for improving bonding abnormality detection effect. Background In the existing module FPC, the bonding bending area of the FPC is subjected to process treatment of printing green oil to reduce bending stress, the conventional green oil printing is performed by using a screen printing process, the tolerance of the printing green oil is usually 0.2mm, and the green oil is brushed into the bonding area of display glass due to unstable process, so that the problems of poor bonding, affected module function and the like are caused, and in the existing method, the problems of inaccurate and insufficient detection and the like are caused, wherein the defects can not be well detected in manual sampling inspection or AOI detection. Accordingly, the prior art has drawbacks and needs improvement. Disclosure of utility model The utility model aims to overcome the defects of the prior art and provide a display module structure for improving bonding abnormality detection effect. The utility model provides a display module structure for improving bonding abnormality detection effect, which comprises display glass and a module FPC, wherein bonding connection ends of the module FPC are bonded and connected in a single-layer region of the display glass, solid copper wires formed by etching are respectively formed on the left side and the right side of the bonding connection ends of the module FPC, the solid copper wires are clung to the lower edge of a press-fit contact region of the module FPC and the display glass, and the solid copper wires have preset widths and preset lengths. Further, the width of the solid copper wire is 0.06mm. Further, the length of the solid copper wire is more than or equal to 0.5mm. By adopting the scheme, the utility model has the beneficial effects that the solid copper wires are arranged at the lower edge of the pressing contact area of the FPC and the display glass by etching, so that the solid copper wires can be used for judging that green oil is suitable for qualification after the single-layer green oil is screen printed, and the AOI automatic equipment and manual inspection are convenient, the detection efficiency and the product yield are improved, and the abnormal bonding product is prevented from flowing into the downstream. Drawings Fig. 1 is a schematic structural diagram of a module FPC according to an embodiment of the present utility model. Detailed Description The utility model will be described in detail below with reference to the drawings and the specific embodiments. Referring to FIG. 1, in the embodiment, the present utility model provides a display module structure for improving bonding abnormality detection effect, which comprises a display glass and a module FPC 1, wherein bonding connection ends of the module FPC 1 are bonded and connected in a single layer region of the display glass, solid copper wires 12 formed by etching are respectively formed on left and right sides of the bonding connection ends of the module FPC 1, the solid copper wires 12 are closely attached to the lower edge of a press-fit contact region 11 between the module FPC 1 and the display glass, the width W of the solid copper wires 12 is 0.06mm, and the length L of the solid copper wires 12 is greater than or equal to 0.5mm. With continued reference to fig. 1, in this solution, the solid copper wires 12 are disposed on both sides of the module FPC 1, and because the etching tolerance is very small, typically ±0.015mm, it can be ensured that the precision of the two solid copper wires 12 meets the requirement, and after the single-layer area greenwash is finished, if the green oil layer 13 passes over the upper edge of the solid copper wires 12, it is indicated that the green oil layer 13 has invaded the press-contact area 11 between the module FPC 1 and the display glass, and the product is bad, because whether it is AOI automatic equipment or manual detection, the problem can be found intuitively. In summary, the utility model has the beneficial effects that the solid copper wires are arranged at the lower edge of the pressing contact area of the FPC and the display glass by etching, so that the solid copper wires can be used for judging that green oil is suitable for qualification after the green oil is printed in a single-layer area by screen, and the AOI automatic equipment and manual inspection are convenient, the detection efficiency and the product yield are improved, and the product with abnormal bonding is prevented from flowing into the downstream.
