Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic equipment technology, and in particular to a liquid crystal display module and electronic equipment. Background Technology
[0002] Conventional LCD modules are typically secured to the casing using a strip of ordinary double-sided tape. To save costs, the casing is usually made of plastic. Because both the casing and the cover have a certain degree of flatness, the double-sided tape bonding is not completely airtight, leaving some extremely fine gaps. These gaps offer good dust and water resistance, but static electricity can easily penetrate them. Furthermore, to achieve a narrow bezel design, the backlight module is often designed without a bezel, so static electricity penetrating through these gaps can directly affect the TFT LCD screen, causing display abnormalities.
[0003] How to solve the above-mentioned technical problems has become an urgent technical challenge for the industry. Utility Model Content
[0004] In order to at least solve the above-mentioned technical problems, the purpose of this utility model is to provide a liquid crystal display module that avoids the direct action of static electricity on the liquid crystal display screen, which would lead to abnormal display phenomena.
[0005] To achieve the above objectives, the liquid crystal display module provided in this application includes:
[0006] A plastic frame with a chamber and a cover plate on the chamber;
[0007] The cover plate and the plastic frame are connected by conductive double-sided adhesive.
[0008] The backlight module is disposed within the cavity;
[0009] Conductive sponge is provided on the side of the backlight module facing the plastic frame;
[0010] A conductive cloth is placed between the conductive sponge and the plastic frame;
[0011] The conductive cloth is connected to the conductive double-sided adhesive.
[0012] An FPC is placed between the conductive sponge and the backlight module;
[0013] The FPC is equipped with a grounding point, which is connected to the conductive sponge.
[0014] Furthermore, the conductive cloth is a single-sided conductive cloth;
[0015] The conductive cloth is attached to the inner wall of the plastic frame.
[0016] Furthermore, the thickness of the conductive cloth is 0.08mm-0.1mm;
[0017] The width of the conductive cloth is 8mm-10mm.
[0018] Furthermore, the conductive sponge is a double-sided conductive sponge.
[0019] Furthermore, the conductive sponge has a length of 10mm and a width of 10mm.
[0020] Furthermore, the thickness of the conductive sponge is larger than the gap between the backlight module and the inner wall of the plastic frame.
[0021] Furthermore, the thickness of the conductive sponge is 0.5mm larger than the gap between the backlight module and the inner wall of the plastic frame.
[0022] Furthermore, a lower glass substrate is provided on the side of the backlight module facing away from the plastic frame;
[0023] The FPC is connected to the lower glass substrate.
[0024] Furthermore, an upper glass substrate is provided on the side of the lower glass substrate facing away from the backlight module;
[0025] The lower glass substrate is larger than the upper glass substrate;
[0026] A bonding position is provided in the area where the lower glass substrate is larger than the upper glass substrate;
[0027] The FPC is bound to the binding bit.
[0028] To achieve the above objectives, the electronic device provided in this application includes: the aforementioned liquid crystal display module.
[0029] In this embodiment of the liquid crystal display module, the electrostatic discharge path is as follows: static electricity is attracted by the conductive double-sided adhesive 114, and then transmitted to the grounding point 104 on the FPC 105 through the conductive cloth 102 and the conductive sponge 103. Because the FPC 105 is connected to the grounding network, the static electricity is released. The complete electrostatic discharge path avoids the static electricity from acting directly on the liquid crystal display screen, which could lead to abnormal display phenomena.
