AI Technical Summary
In existing technologies, the copper leakage area of display modules is prone to the problem of missing openings during the manufacturing process, resulting in static electricity loss. Downstream manufacturers cannot determine whether the conductive cloth is set correctly, leading to the scrapping of the module.
An open area is formed at the edge of the conductive cloth to expose the exposed copper area, allowing machines and the human eye to visually identify the copper exposure settings and preventing incorrectly configured modules from being made into display modules.
This improves the ESD reliability of the display module, avoids the problem of module scrapping during ESD testing or use, and enhances the reliability of electrostatic discharge.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of display module technology, and in particular to a display module that improves the ESD reliability of the module. Background Technology
[0002] In display modules used in electronic devices such as mobile phones, the anti-static capability of the display module is crucial. Currently, the industry practice for releasing static electricity in display modules involves creating copper-exposed openings on the FPC module and then completely covering the exposed copper area with conductive cloth, thereby releasing static electricity onto the entire casing of the electronic device. However, the copper-exposed openings on the FPC module are done during the manufacturing process by the FPC manufacturer, and subsequent processes do not involve secondary openings. This results in the problem of incomplete openings in the exposed copper areas. Furthermore, since the conductive cloth is also applied to the exposed copper areas at the FPC manufacturer, downstream display module manufacturers cannot determine whether copper exposure is properly implemented under the conductive cloth. If copper exposure is not implemented, the module will suffer static electricity damage during subsequent ESD testing, leading to scrapping and significant losses.
[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 improves the ESD reliability of the module.
[0005] The technical solution of this utility model is as follows: This utility model provides a display module that improves the ESD reliability of the module, including: a module FPC, wherein a copper leakage area is formed on the module FPC, and a conductive cloth is attached to the copper leakage area, wherein the conductive cloth does not completely cover the copper leakage area.
[0006] Furthermore, an open area is formed at the edge of the conductive cloth, and the exposed copper area is exposed below the open area.
[0007] Furthermore, the clearance area is square, and the width of the clearance area is 0.15mm-0.4mm.
[0008] Furthermore, the solution also includes a display unit, wherein a first connector for binding to the display unit is formed on the module FPC, and the clearance area is located on the side of the conductive cloth near the first connector.
[0009] Furthermore, the solution also includes a backlight module, wherein the display unit is a liquid crystal display unit, and the backlight module and the display unit are stacked together.
[0010] The beneficial effects of this utility model by adopting the above solution are as follows: by setting an empty area on the conductive cloth to expose the exposed copper area below, both the machine and the human eye can intuitively and quickly identify whether the exposed copper is set correctly, thus avoiding the problem of the FPC module with incorrectly set exposed copper being made into a display module, which would cause the subsequent module to be scrapped during ESD testing or use, thereby improving the ESD reliability of the display module. Attached Figure Description
[0011] Figure 1 This is a schematic diagram of the structure of a module FPC according to an embodiment of the present invention.
[0012] Figure 2 for Figure 1 Enlarged view of point A in the middle. Detailed Implementation
[0013] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0014] Please refer to the following: Figure 1 and Figure 2 In this embodiment, the present invention provides a display module that improves the reliability of the EDS module, comprising: a module FPC 1, wherein an exposed copper area 3 is formed on the module FPC 1, and a conductive cloth 2 is attached to the exposed copper area 3, wherein the conductive cloth 2 does not completely cover the exposed copper area 3.
[0015] Specifically, an open area is formed at the edge of the conductive cloth 2, and the exposed copper area 3 is exposed below the open area.
[0016] Specifically, the clearance area is square, and the width W of the clearance area can be 0.15mm-0.4mm. This allows for easy observation of whether there is any exposed copper underneath, and also ensures that the grounding and conductivity of the conductive cloth 2 can be performed normally.
[0017] Furthermore, the display module also includes a display unit, which is a liquid crystal display unit. A first connector 4 for binding with the display unit is formed on the module FPC 1. The clearance area is located on the side of the conductive cloth 2 near the first connector 4. The backlight module and the display unit are stacked together.
[0018] In this solution, the conductive cloth 2 does not completely cover the exposed copper area 3 of the module FPC 1. If the exposed copper area 3 of the module FPC 1 is not properly opened to allow copper leakage, it can be easily observed through the open area of the conductive cloth 2, thus preventing damage to the display module caused by improperly set copper leakage in the module FPC 1.
[0019] In summary, the beneficial effects of this solution are as follows: by setting a void area on the conductive cloth to expose the exposed copper area below, both machines and human eyes can intuitively and quickly identify whether the exposed copper is correctly set. This avoids the situation where FPC modules with incorrectly set copper are used to make display modules, which would cause subsequent module scrapping during ESD testing or use, thus improving the ESD reliability of the display modules.
[0020] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
