It is a technology that can be easily attached to and detached from the surface of the LCD, and the space between the LCD and the module holder is prevented to prevent shaking of the LCD, thereby facilitating subsequent processes and thereby improving the yield and productivity of the LCD device.

Description

Silicon rubber for liquid crystal display

The present invention relates to a silicone rubber for a liquid crystal display device for fixing the LCD in a liquid crystal display (hereinafter referred to as an LCD) module, and in particular, a band-type silicon rubber is used to be detachable in a simple process. The present invention relates to a technology for improving the stability of LCD devices.

LCD, which is a kind of flat panel display device, changes the optical anisotropy by applying an electric field to liquid crystal, which combines the liquidity of liquid and the optical characteristics of crystal.It has lower power consumption than conventional cathode ray tube. It is widely used because it is easy to make small and light, small and large, and high in size.

In general, an LCD panel is formed by bonding a transparent liquid crystal pattern, a lower liquid crystal substrate on which a pixel electrode is connected to a switching element, and an upper liquid crystal substrate on which a common electrode is formed with a failure turn and a spacer, and sealing the liquid crystal in the space therebetween. do.

Since the LCD panel does not display the screen independently, a light emitting device, for example, an EL (electroluminescence) device or a light emitting diode (hereinafter, referred to as an LED) panel is shown below. Or in the form of a module with a cold cathode fluorescence lamp (hereinafter referred to as CCFL).

1 to 3 are views for explaining a liquid crystal display module according to the prior art, and will be described in association with each other.

First, a backlight panel having a CCFL 15 and a light guide plate 13 is mounted on a plastic frame 27, and an LCD cell 11 is fixed to an upper portion of the backlight panel, and a side surface of the LCD cell 11 is provided. There is a PCB 17 connected by a tap-IC 19. At this time, the tab-IC 19 and the PCB 17 are connected by soldering.

And holder 25 of rectangular frame shape which fixes LCD cell 11, PCB 17, tab-IC 19, back light, plastic frame 27, etc. is covered. At this time, the double-sided tape 29 is attached to the two-sided portion in contact with the holder 25 of the LCD cell 11 has a straight silicon rubber 31 is attached, the LCD cell 11 is fixed pin 28 Both sides are fixed by this.

The silicon rubber for the liquid crystal display device formed by the above-mentioned conventional technology requires a double-sided tape, and the unit cost increases when applied, and it is difficult to fix the LCD because it is a thin, long rod-shaped rubber made of silicon. And lowering the yield.

Accordingly, an object of the present invention is to provide a silicon rubber for a liquid crystal display device that can improve the productivity and yield of an LCD device by forming a silicon rubber in a band shape in order to solve the problems of the prior art.

1 is a partial cross-sectional view of a liquid crystal display module according to the prior art.

FIG. 2 is a schematic view for explaining the silicon rubber portion of FIG. 1. FIG.

3 is a perspective view of the silicon rubber of FIG.

Figure 4 is a schematic diagram for explaining an LCD module using a silicon rubber for a liquid crystal display according to an embodiment of the present invention.

In order to achieve the above object, the liquid crystal display silicon rubber according to the present invention, in the liquid crystal display silicon rubber interposed between the LCD cell and the holder in order to prevent damage to the LCD during the LCD module forming process. The silicon rubber may be formed in a band shape.

On the other hand, the principle of the present invention for achieving the above object, by forming the silicone rubber in a band shape so that it can be formed on the upper, lower and both sides of the LCD, and easy removal of the silicone rubber, the silicone rubber in the space with the fixing pin By forming a structure that is formed to prevent damage to the LCD by the fixing pin.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

First, each structure is formed on the upper liquid crystal substrate or the lower liquid crystal substrate, the spacers are dispersed, and then the silicon rubber (B) is mounted on the LCD module to mount the LCD 11 formed by bonding the upper or lower liquid crystal substrate with a failure turn. 31).

At this time, the silicon rubber 31 is located in the empty space with the pin to fix the LCD (11) serves to prevent damage by fixing the LCD (11).

As described above, the silicon rubber for liquid crystal display device according to the present invention is formed with a band-shaped silicon rubber at the silicon rubber attachment portion of the LCD to facilitate the detachment of the silicon rubber and to the bin with a fixing pin for fixing the LCD. Filling the space has the effect of improving the yield and productivity of the LCD device.
