Description

Liquid crystal display device having a plurality of LCD modules {LIQUID CRYSTAL DISPLAY HAVING A PLURALITY OF LCD MODULE}

The present invention relates to a liquid crystal display device, and more particularly, it is possible to partially assemble and disassemble the unit LCD module from the liquid crystal display device formed by combining a plurality of LCD modules, Increased adhesion prevents the display area of the liquid crystal display from being split, and prevents the luminance from deteriorating due to light leaking to parts other than the LCD module and prevents the light source from being damaged from external impact. It relates to a liquid crystal display device having a.

In recent years, due to the development of semiconductor manufacturing process technology, the arrangement of the thin film transistor (TFT) and the electric field is changed, and thus the light passing and blocking phenomenon, that is, the liquid crystal material, which is an intermediate between solid and liquid, having optical shutter function The development has led to the development of a digitally driven LCD module that is significantly reduced in size and weight compared to the existing CRT method.

The LCD module is applied to any one of the two transparent pixel electrodes facing each other in a state in which the thin film transistor, which is manufactured by the application of the semiconductor thin film technology, is turned on and is transparent and spaced at a predetermined area and a predetermined interval so that an electric field is formed. At the same time, the liquid crystal injected between the two pixel electrodes in which the electric field is formed is rearranged at an angle by the electric field, and the light passing through the liquid crystal by the rearrangement of the liquid crystals stimulates any one of the RGB pixels so that a predetermined color is transferred to the outside Allow expression.

In order to implement this, a thin film transistor, which is essential in an LCD module, is formed on a transparent substrate capable of transmitting light, and a glass substrate having a predetermined strength and melting at a relatively high temperature is used. However, since the glass substrate has a large specific gravity, warpage or deflection easily occurs when the size increases, and process defects occur when the thin film transistor manufacturing process is performed while warpage or deflection occurs.

For this reason, there are many problems in manufacturing LCD modules having a size of about 30 "or more in general.

Recently, in order to overcome such manufacturing limitations of LCD modules, liquid crystal displays have been developed in which edges of a plurality of unit LCD modules are bonded to each other and each unit LCD module is individually driven, but a completed image is generated as a whole. have.

As shown in FIG. 1, the liquid crystal display device 10 includes a plurality of unit LCD modules 1 mounted in a mounting manner on the mounting frame 3 to have a matrix form.

In this case, when the boundary surface 1a of the unit LCD module 1 and the unit LCD module 1 are opened even a little, a plurality of mounting frames 3 may be provided in order to prevent the screen from being divided by the opened boundary surface 1a. A pressing piece 5 for pressing all the unit LCD modules 1 located at the outermost side of the mounted unit LCD modules 1 in one direction is installed in a sliding manner with respect to the mounting frame 3.

The cold cathode ray tube (not shown) as a light source is installed in the mounting frame 3 so as to penetrate the plurality of unit LCD modules 1 closely fixed to each other, and both ends of the cold cathode ray tube are disposed of the unit LCD module 1. It is connected to a power supply terminal (not shown) from the outside.

However, in the case of the conventional liquid crystal display device 10, since all the unit LCD module 1 is pressurized by one pressing piece 5, repair is performed when any one of the plurality of unit LCD modules 1 is damaged. And difficult to replace.

In another problem, since the conventional pressing piece 5 presses the unit LCD module 1 only in one direction, the unit LCD module 1 flows in a direction other than the pressing direction so that a gap occurs in the interface as a result of the flow. There is a problem that the screen is divided.

Another problem is that the end of the cold cathode ray tube, which is very fragile, protrudes from the unit LCD module 1 without any protective device, causing frequent breakage.

The larger problem that occurs when the end of the cold cathode ray tube protrudes from the unit LCD module 1 is the colder of the area surrounding the liquid crystal display device 10 than the light brightness of the display area of the actual liquid crystal display device 10. There is a problem that the display area becomes dark because the light brightness of the exposed portion of the cathode ray tube is greater.

Accordingly, the present invention has been made in view of the various problems described above, and an object of the present invention is to facilitate disassembly / assembly of a unit LCD module from a liquid crystal display device composed of a plurality of LCD modules.

Another object of the present invention is to prevent the division of the screen by the flow of the front, rear, left and right of the unit LCD module does not occur.

Another object of the present invention is to protect the end of the light source protruding from the unit LCD module not to be damaged and to prevent the light of the light source protruding from the unit LCD module from leaking to the outside.

Another object of the present invention will become more apparent from the detailed description of the invention which will be described later.

Meanwhile, the common light source 715 is provided on two surfaces of the inner plate 880 parallel to the cut surface of the outer plate 870 formed as described above to be coupled with the socket plate 630 and the LCD module disassembly / assembly apparatus 800. The semicircular groove 882 is formed in the place where the light source passes so that can pass through.

A plurality of pressing pieces 884 for pressing the unit LCD module 710 are formed on two surfaces of the inner plate 880 and the remaining two surfaces between the semicircular grooves 882 and the semicircular grooves 882. .

Here, the pressing piece 884 preferably cuts a portion of the inner plate 880 into a "U" shape, and then cuts a predetermined height from the surface of the tongue-like pressing piece body 884a formed therein. At least one pressing protrusion 884b is formed to protrude.

A plurality of the pressing pieces 884 formed as described above are formed along the inner plate 880 such that at least one pressurizes the unit LCD module 710, and preferably two pressing protrusions are provided at both ends of the surface of the cut member. 884b is formed.

Even though the LCD module flow preventing cover 850 formed as described above is coupled to the base plate 610 of the mounting frame 600, the stepped joint coupling is very vulnerable to external force, so that the LCD module flow preventing cover 850 is reinforced. A through hole 890 is formed in a portion corresponding to the boss 670 formed in the base plate 610, and the boss 670 and the through hole 890 are screwed and fixed by fastening screws.

As a result, each unit LCD module 710 is prevented from flowing by the LCD module flow preventing cover 850 so that the display area is not divided, and the common light source 715 having a very low impact resistance is prevented from external impact. In addition to protecting, the light leakage of the common light source 715 can be completely prevented to prevent the periphery of the display area from becoming brighter than the display area.

As described in detail above, when any one of the LCD module group consisting of a plurality of unit LCD modules needs to be replaced, only the row belonging to the unit LCD module to be replaced among the LCD module groups is disassembled and replaced. The time required can be greatly reduced, and the breakage of the common light source can be proactively prevented by unexpected external shocks caused by the exposure of the common light source that is weak to impact. Therefore, there is an effect of preventing the brightness unevenness of the display area caused by the difference between bright and dark.
