Abstract

In the liquid crystal display module, when static electricity is applied to the liquid crystal display device, the static electricity is prevented from penetrating into the LSI connected to the PCB through the zebra connector to lose the LSI. On top of the upper glass substrate of the upper surface of the bezel is coated with a protective film for preventing static electricity penetration in close contact with the inner surface.

[Industrial use]

The present invention relates to a liquid crystal display module, and more particularly, to a liquid crystal display module that can prevent deterioration of the quality of a liquid crystal display due to damage of a high density integrated circuit (LSI) due to static electricity. will be.

[Prior art]

In general, a module of a conventional liquid crystal display includes a liquid crystal display device, a PCB for applying an electrical signal to the liquid crystal display device to control wiring patterns of the liquid crystal display, a zebra connector interposed between the PCB and the liquid crystal display device; It is configured to include a backlight.

That is, in the conventional liquid crystal display module structure, the coupling relationship of the components is first, the PCB is disposed opposite to the bottom of the liquid crystal display device in a state where the liquid crystal display device is disposed at the center portion.

In this state, both ends of the liquid crystal display and the PCB are connected to each other by a zebra connector, and a backlight for injecting light into the liquid crystal display is mounted between the liquid crystal display and the PCB.

Each of the components constituting the coupling structure is formed in one of the liquid crystal display module by integrally surrounded by the bezel coupled to the PCB by forming an opening in the center portion thereof.

[Problem to solve]

However, a problem with the liquid crystal display module is that when static electricity is applied to the liquid crystal display device, the quality of the liquid crystal display is degraded due to the static electricity.

This phenomenon especially occurs in a large liquid crystal display, that is, when using the liquid crystal display with the module structure, when static electricity is directly applied to the liquid crystal display, the static electricity flows through the zebra connector and enters the PCB. This is due to the penetration into the LSI connected to the bottom of the PCB.

Accordingly, the LSI is damaged by the penetrated static electricity, and the damage of the LSI degrades the function of the liquid crystal display, so that the quality of the liquid crystal display having the module structure is deteriorated.

Accordingly, the present invention was devised to solve the above problems, and prevents static electricity from being applied to the liquid crystal display device from penetrating into the LSI attached to the PCB, thereby preventing damage to the LSI and deterioration of the quality of the liquid crystal display. It is an object of the present invention to provide a module of a liquid crystal display.

[Means to solve the problem]

In order to realize the neck, the present invention connects a liquid crystal display device and a PCB with a zebra connector, and mounts a backlight for projecting light onto the liquid crystal display device above the PCB, and the liquid crystal display device on the PCB. A liquid crystal display module comprising a bezel that wraps the liquid crystal display device, the backlight, and the like from an outer side of the liquid crystal display device, wherein the liquid crystal display module is in close contact with an inner surface of the upper plate of the bezel on the front surface of the upper glass substrate of the liquid crystal display device. Provided is a liquid crystal display module formed by coating a protective film.

EXAMPLE

Hereinafter, with reference to the accompanying drawings, preferred embodiments to help understand the present invention in detail as follows.

1 is a side cross-sectional view for explaining the module of the liquid crystal display according to the present invention.

As shown in the figure, the liquid crystal display module according to the present invention has a PCB 3 disposed on the bottom surface of the liquid crystal display device 1, similarly to a normal liquid crystal display, and the liquid crystal display device 1 and the two end portions therebetween. A zebra connector 5 for connecting the PCB 3 is interposed therebetween, and a back light 7 for projecting light onto the liquid crystal display 1 is provided on the upper side of the PCB 3. In the mounted state, the bezel 9 forms a structure in which the bezel 9 is integrally wrapped with the PCB 3 from the outside of the upper side of the liquid crystal display device 1 and combined with the PCB 3.

In this module structure, the present invention is further provided with a protective film for preventing static electricity to prevent static electricity applied to the liquid crystal display device 1 from penetrating into the LSI 11 connected to the lower side of the PCB 3. .

As shown in the drawing, the passivation layer 13 is formed of an ITO film having a predetermined thickness between the upper polarizing plate 1a and the glass substrate 1b in the liquid crystal display device 1. The peripheral portion of the protective film 13 is to be in close contact with the lower surface of the upper portion of the bezel (9).

Accordingly, in the liquid crystal display module of the present invention including the protective film 13, when static electricity is applied to the liquid crystal display device 1 during the operation of the liquid crystal display, the static electricity is transferred to the upper polarizing plate 1a and the glass. Passing through the substrate (1b), as described above, the protective film 13 is connected to the bezel (9) is led to the bezel (9).

Accordingly, since the static electricity induced by the bezel 9 may be grounded, the static electricity passes through the zebra connector 5 and passes through the PCB 3 toward the LSI 11. Penetration becomes impossible.

Therefore, the present invention has a modular structure that can use a liquid crystal display without damaging the LSI 11 to static electricity.

[Effect of design]

As described above, in the liquid crystal display module according to the present invention, the protective film prevents the static electricity applied to the liquid crystal display device from penetrating into the LSI, thereby preventing the loss of the LSI due to the static electricity and the quality of the liquid crystal display due to the loss of the LSI. It can have the effect of preventing damage.
