AI Technical Summary
In existing technologies, when the high-temperature adhesive is designed to be far from the edge of the copper foil, the long handle structure increases material costs and is easily knocked off, leading to increased rework costs.
An observation hole is set on the copper foil to visually observe whether the high-temperature adhesive has been missed, thus avoiding the use of long handle structures.
It achieves reliable identification of high-temperature adhesive leakage, avoids the problem of long handles being knocked off, and reduces material and rework costs.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of display module technology, and in particular to a display module for preventing high-temperature adhesive from leaking out. Background Technology
[0002] The mobile phone industry is demanding increasingly higher reliability from display modules. To prevent short circuits between the module's FPC components and other metals, high-temperature adhesive is typically applied to the component areas. Furthermore, to prevent component interference, copper foil is often applied over the high-temperature adhesive. Current high-temperature adhesive anti-leakage designs involve extending the adhesive strip beyond the copper foil application point for visual and machine identification. This method is suitable when the high-temperature adhesive is close to the copper foil edge. If the adhesive is positioned further away, the extended handle needs to be significantly longer to be visible. This structure increases the amount of adhesive material required, incurring higher material costs. Moreover, the protruding handle makes the adhesive more susceptible to being knocked off by machines or personnel after numerous processing steps, increasing rework costs.
[0003] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a display module that prevents high-temperature adhesive from leaking out.
[0005] The technical solution of this utility model is as follows: This utility model provides a display module to prevent high-temperature adhesive from being missed, including: a module FPC, on which high-temperature adhesive is applied, and on which a copper foil covering the high-temperature adhesive is applied, and an observation hole is formed on the copper foil at the position corresponding to the application of the high-temperature adhesive.
[0006] Furthermore, the observation hole is located at the edge region of the high-temperature adhesive.
[0007] Furthermore, the observation hole is circular with a diameter of 1.3mm-2mm.
[0008] Preferably, the diameter of the observation hole is 1.6 mm.
[0009] Furthermore, the display module also includes a liquid crystal module and a backlight module, wherein the backlight module is stacked on the lower layer of the liquid crystal module, and the liquid crystal module is bonded and connected to the module FPC.
[0010] The beneficial effects of this utility model by adopting the above solution are as follows: by setting an observation hole on the copper foil, the high-temperature adhesive that is covered by the copper foil can be directly observed through the observation hole, making it easy to identify whether the high-temperature adhesive has been missed, and also avoiding the problem of the high-temperature adhesive being knocked off by the long handle form in the prior art.
