BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display unit for a liquid crystal display device, and more particularly, to a portion of a liquid crystal panel in which an OEL pad (OLB pad) (hereinafter, referred to as an "OLB pad") is not formed. By arranging a series of uneven pads, the adhesive film is connected to the adhesive film by inducing a stable support base not only in the "OLB pad formed area" but also in the "OLB pad formed area". The present invention relates to a display unit for a liquid crystal display device which can prevent an unexpected peeling phenomenon of a signal connection member in advance.

Recently, as the modern society becomes information socialized, the importance of the liquid crystal display device, which is one of the information display devices, is gradually increasing. In particular, the liquid crystal display device due to its advantages such as small size, light weight, low power consumption, etc. As an alternative means to overcome the shortcomings of the CRT (Cathode ray tube), the use area is gradually increasing.

In general, a plurality of drive ICs for driving thin film transistor patterns are typically mounted in a liquid crystal display, and the drive ICs have overall performance of the device among the components constituting the liquid crystal display. It is a very important part that determines.

In this case, the method of mounting the drive IC in the liquid crystal display device is large, and there is a chip on glass (COG) mounting method in which the drive IC is directly mounted in the gate area and the data area of the liquid crystal panel without any structure. It is divided into a tape automated bonding (TAB) mounting method in which the drive IC is indirectly mounted in the gate region and the data region of the liquid crystal panel through the IC-mounted signal connection member.

Here, when the tab mounting method is applied by mounting the drive IC in the liquid crystal display, the signal connection member including the drive IC, for example, a tape carrier package, is mounted with a printed circuit board. By being electrically connected to the liquid crystal panel, the liquid crystal panel and the printed circuit board are electrically connected to each other, which in turn assists the drive IC to quickly perform its assigned functions.

A general structure of such a signal connection member is disclosed in, for example, US Patent No. 4832455, "Liquid crystal apparatus having an anisotropic conductive layer between the lead electrode of the liquid crystal element and the circuit board. liquid crystal device and the circuit board ", US Patent No. 5258866" Method of connecting liquid crystal display and circuit board with thermal expansion compensation " 5572346 "Tape carrier for LCD driver package with anchor holes on either side of and spaced 0.2mm to 10mm from the chip mounting site ", US Patent No. 5587557" Printed circuit board and liquid crystal di splay) "and the like.

In this case, an adhesive film such as an anisotropic conductive film (ACF) is disposed on the edge surface of the liquid crystal panel. The adhesive film acts as an intermediate medium for electrically and physically fixing the above-mentioned signal connection member to the liquid crystal panel in a state where it is mounted on the edge surface of the liquid crystal panel, so that the signal connection member functions as a signal path granted to the liquid crystal panel. Make it work smoothly.

Here, an OEL pad (OLB pad: Out Lead Bonding pad: electrically connected to gate lines and data lines of the liquid crystal panel) may be formed on an edge of the liquid crystal panel overlapping the adhesive film. OLB pads " The OLB pad is formed in electrical contact with the signal connection member while overlapping the adhesive film, so that the electrical signal processed by the drive IC can be smoothly introduced into the above-described gate liner and data lines. do.

As such, since the adhesive film serves as an intermediate medium for electrically and physically fixing the signal connection member and the liquid crystal panel separated from each other, if the adhesive film causes an unexpected failure, the liquid crystal display device to be finally shipped is It causes a great damage to their electrical signal system, and eventually causes a problem of failing to maintain a certain level of quality. In the conventional production line, in view of such a problem, a lot of efforts are made to prevent the failure of the anisotropic conductive film.

As described above, in the conventional production line, in consideration of the fact that the defect of the adhesive film has a great adverse effect on the quality of the liquid crystal display device to be finally shipped, a lot of efforts have been made to prevent the occurrence of defect of the adhesive film. Despite the efforts, some kinds of defects caused in the adhesive film are not easily solved. Representative examples of such defects include the problem of "partial peeling of the adhesive film".

As described above, the OLB pad is disposed on the edge surface of the liquid crystal panel, and the OLB pad forms a structure overlapping with the adhesive film. In this case, the adhesive film is “uneven structure naturally formed by the outer profile of the OLB pad. By securing a stable support base, it is possible to maintain a solid contact structure for a long time.

However, such a conventional OLB pad is not formed in the entire area of the edge surface of the liquid crystal panel, but is generally formed only in the "partial edge area of the liquid crystal panel" corresponding to the "part on which the signal connection member is mounted". In the conventional production line, there is a serious problem that "the solid contact structure of the adhesive film can be maintained only in some areas where the OLB pad is formed, and the solid contact structure of the adhesive film cannot be maintained in the remaining areas where the OLB pad is not formed". You have to accept it.

If, due to the structural fragility of the "region where no OLB pad is formed", in this region, the rapid peeling process of the adhesive film is caused, this partial peeling process rapidly reaches the "region where the OLB pad is formed". As a result, in the production line, the entire surface of the adhesive film is bound to suffer a serious problem of peeling off the edge of the liquid crystal panel.

When the adhesive film is completely separated from the edge of the liquid crystal panel through this process, the signal connection member cannot form a normal electrical / physical connection relationship with the liquid crystal panel. The electrical signal system is seriously damaged and the normal quality cannot be maintained.

Of course, maximizing the adhesive force of the adhesive film is the best solution to fundamentally solve this problem, but in the prior art level, there are some limitations in maximizing the adhesive force of the adhesive film, the above problems in the conventional production line Although they are deeply aware of the situation, they have not prepared a specific response plan.

Therefore, an object of the present invention is to arrange a series of uneven pads in the "part area of the liquid crystal panel in which no OLB pad is formed", and the adhesive film is not only in the "area where the OLB pad is formed" through the uneven pads, but also in the "OLB pad". It is to induce a stable support base even in an area where no is formed.

Another object of the present invention is to prevent the unexpected peeling phenomenon of the signal connection member connected to the adhesive film by maintaining an even contact structure over the entire area of the edge surface of the liquid crystal panel.

Another object of the present invention is to prevent the separation of the signal connection member in advance, to induce the final shipping liquid crystal display device to maintain a normal signal connection system.

Still other objects of the present invention will become more apparent from the following detailed description and the accompanying drawings.

In order to achieve the above object, in the present invention, a plurality of fixing patterns forming a concave-convex shape are formed on the “part area of the liquid crystal panel in which the OLB pad is not formed”. These fixed patterns form, for example, a structure disposed between the data OLB pads, or a structure disposed between the gate OLB pads.

At this time, since each fixing pattern forms a natural anchor structure by its outer profile, when the present invention is achieved, the adhesive film, for example, an anisotropic conductive film can secure a stable fixing base smoothly. .

When the present invention is achieved, the adhesive film may form a stable fixing structure not only in the "region in which the OLB pad is formed" but also in the "region in which the OLB pad is not formed", in this case, the signal connection connected to the adhesive film. The member does not cause unexpected delamination, and as a result, the final liquid crystal display device can maintain a normal signal connection system.

Hereinafter, a display unit for a liquid crystal display according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, in the liquid crystal display device 100 employing the display unit 200 according to the present invention, the mold frame 10 may, for example, stack and store the light guide plate 14 and sheets 15. It has a rectangular ring shape so that the receiving area to be defined. At this time, for example, the lamp 13 having the light irradiation function is housed in a state of being enclosed by the lamp cover 12 at the long edge of the storage area.

The lamp 13 is connected to a connector (not shown) by a wire, and this connector supplies the lamp 13 with an appropriate electric voltage to induce the lamp 13 to emit light at a constant brightness. Do this.

Here, the light guide plate 14 disposed on the side of the lamp 13 serves to convert the light of the line light source output from the lamp 13 into the light of the surface light source.

In this case, a plurality of reflective dots (not shown) are formed on the rear surface of the light guide plate 14 to diffuse the light incident from the lamp 13. These reflecting dots keep their size small in the area adjacent to the lamp 13, leading to a decrease in the total light spread amount, and keeping the size large in a region away from the lamp 13, thereby increasing the overall light spread amount. Induce as much as possible.

On the other hand, a rear reflector 11 is disposed on the rear surface of the light guide plate 14 to block the light incident from the lamp and reflect the light back toward the light guide plate, and the sheets 15 on the front surface of the light guide plate 14 corresponding thereto. This is arranged laminated.

Looking at the structure of these sheets 15 in more detail, first, a diffuser plate 15a is formed on the surface closest to the light guide plate 14 to uniformly control the light incident from the lamp 13, and also diffuses. On the front surface of the plate 15a, for example, a prism sheet 15b for improving the linear brightness of incident light is formed in a double. In general, since the prism sheet 15b is sensitive to scratches, a protective film 15c having a protective function is attached to the entire surface of the prism sheet 15b to protect the prism sheet 15b.

At this time, the top chassis 16 coupled to the upper portion of the mold frame 10 and surrounding the edge thereof has a rectangular container shape in which a window is formed on the front surface, for example, made of a material such as stainless steel. In this case, the size of the window is formed to correspond to the effective display area of the liquid crystal panel 220 according to the present invention. In addition, the side wall is extended by a predetermined height from the top, bottom, left and right edges so that the bottom surface has a predetermined depth, in this case, the height of the side wall should be maintained to a size enough to wrap the above-described mold frame 10.

Meanwhile, the display unit 200 unique to the present invention is interposed between the sheets 15 and the top chassis 16 described above to substantially display image information input from the outside.

In this case, as shown in FIG. 2, the display unit 200 includes a liquid crystal panel 220 and a gate signal connection member 214 having a series of electrical connection relationships with the liquid crystal panel 220, and a signal connection for data. The member 242, the gate printed circuit board 260, the data printed circuit board 240, and the like are combined.

Here, the liquid crystal panel 220 is, for example, a lower panel 221 including a "gate line, a data line, a thin film transistor, a pixel electrode", and the like, and, for example, in a state of being kept smaller than the lower panel 221. The lower panel 221 is stacked to face each other, and is formed of a combination of the upper panel 222 having, for example, a "black matrix, color pixel, common electrode," and the like. In this case, a liquid crystal (not shown) is interposed between the upper panel 222 and the lower panel 221.

In this case, as shown in FIG. 3, the above-described gate signal connecting member 214 forms a structure overlapping the signal lines formed on the lower panel 221, for example, the gate lines 236, and the data connection of data. The member 242 has a structure overlapping with other signal lines, for example, data lines 233, formed on the lower panel 221.

Here, the aforementioned gate printed circuit board 260 serves to input a series of gate driving signals to the gate signal connection member 214 in a state where a plurality of gate driving components 261 are mounted. In addition, the data printed circuit board 240 serves to input a series of data driving signals to the data signal connection member 242 in a state where a plurality of data driving components 241 are mounted.

Meanwhile, a plurality of thin film transistors (not shown) are arranged in a matrix shape in the lower panel 221, wherein "source terminals of all thin film transistors corresponding to one column" are one side of the lower panel 221. The gate terminals of all the thin film transistors corresponding to one row may be connected to the gate lines extending to one end of the lower panel 221. Achieve.

At this time, as shown in the figure, the gate lines 236 are equally spaced in the effective display area in which a substantial image is displayed through the liquid crystal panel 220, but the ratio corresponding to the edge surface of the lower panel 221 is shown. In the effective display area, in order to facilitate the connection with the gate signal connecting member 214, a series of groups gathered at narrow intervals are formed. In the figure, three groups of gate lines 236 are shown as an example.

In addition, the data lines 233 are equally spaced in the effective display area in which a substantial image is displayed through the liquid crystal panel 220, similar to the gate lines 236 described above. In the non-effective display area corresponding to the above, the source signal connecting member and the 242 are gathered at a narrow interval to facilitate the connection. In the figure, for example, three groups of data lines 233 are shown.

Here, as shown in the figure, the signal connection member 242 for data includes a plurality of drive signal transmission patterns 243 and the drive IC 246 for data in electrical contact with the drive signal transmission patterns 243. Is made up of a combination.

In this case, the driving signal transmission patterns 243 have a structure in which, for example, the data signal connection member 242 is fixed to the lower panel 221, for example, in contact with the data lines 233 of the lower panel 221. In this way, the data driving signal output from the data printed circuit board 240 can be quickly transmitted to the source terminal of the thin film transistor.

In addition, the gate signal connecting member 214, like the data signal connecting member 242 described above, has a plurality of driving signal transmission patterns 213 and a gate in electrical contact with the driving signal transmission patterns 213. For the drive IC 250.

In this case, the driving signal transmission patterns 213 are in contact with the gate lines 236 of the lower panel 221 when the gate signal connecting member 214 is fixed to the lower panel 221. In this way, the gate driving signal output from the gate printed circuit board 260 can be quickly transmitted to the gate terminal of the thin film transistor.

Here, the OLB pad 1 for data is disposed at the ends of the above-described data lines 233. If the data OLB pad 1 is fixed while the data signal connection member 242 is overlapped with the lower panel 221, the driving signal transmission patterns of the data signal connection member 242 are fixed. By electrically contacting 243 to form a smooth energizing relationship, the drive signal processed by the data drive IC 246 can be quickly input to the data lines 233 of the lower panel 221.

In addition, an OLB pad 2 for a gate is disposed at an end portion of the gate lines 236 described above. The gate OLB pad 2 may include driving signal transmission patterns of the gate signal connecting member 214 when the gate signal connecting member 214 is fixed to overlap the lower panel 221. Electrical contact with 213 forms a smooth energizing relationship, so that the driving signal processed by the gate drive IC 250 can be quickly input to the gate lines 236 of the lower panel 221.

At this time, as shown in the figure, the first adhesive film 30, for example, the first anisotropic conductive film is disposed on the surface of the liquid crystal panel 220, for example, the data lines 233 of the lower panel 221. The second adhesive film 31, for example, the second anisotropic conductive film, is disposed on the edges of the lower panels 221 toward the gate lines 236. In this case, the first and second adhesive films 30 and 31 form a bar shape, for example.

Here, the first adhesive film 30 has a structure overlapping with the data OLB pads 1 before the data signal connecting members 242 are in contact with the data OLB pads 1. In this case, the data signal connecting member 242 serves as an intermediate medium to be electrically and physically fixed to the lower panel 221, so that the data signal connecting member 242 is a signal path given to the user. It should be able to perform the function smoothly.

In addition, the second adhesive film 31 has a structure overlapping with the gate OLB pads 2 before the gate signal connecting members 214 are in contact with the gate OLB pads 2. By acting as an intermediate medium that allows the gate signal connecting member 214 to be electrically and physically fixed to the lower panel 221, the gate signal connecting member 214 as a signal path given to it Make the function run smoothly.

Since the first and second adhesive films 30 and 31 serve as intermediate media for electrically / physically fixing the signal connection members / gate signal connection members 242 and 214 and the liquid crystal panel 220. If the first and second adhesive films 30 and 31 cause an unexpected failure, the final liquid crystal display device may be damaged by its electrical signal system, and thus maintain a certain level or more of quality. Cause problems.

At this time, as shown in the figure, in one embodiment of the present invention, for example, a plurality of fixing patterns (e.g., a plurality of fixing patterns on the edges of the data lines 233 of the lower panel 221 overlapping the first adhesive film 30). 3) to protrude. In this case, the remaining area of the lower surface 221 of the data lines 233 toward the data lines 233 is filled with a plurality of fixing patterns 3, in which the data OLB pad 1 is not formed.

Each of the fixing patterns 3 may be positioned at the outermost surface of the lower panel 221 which may be in direct physical contact with the first adhesive film 30. For example, the fixing patterns 3 may be naturally formed by their outer profile. Because the anchor structure is formed, in the state where the fixing patterns 3 are disposed in advance, the first adhesive film 30 described above overlaps the edges of the lower surfaces 221 of the data lines 233. In this case, the first adhesive film 30 may smoothly secure a more stable fixing base by the action of the fixing patterns 3.

The structure of the fixing patterns 3 is a part of the gist of the present invention. Of course, the fixing patterns 3 are not formed at all in the conventional lower panel.

In the conventional case, since each fixing surface of the lower panel was not provided with any fixing member for fixing the adhesive films in addition to the OLB pads, in the conventional production line, "the firm contact of the adhesive film only in a part of the region where the OLB pad was formed. It was necessary to bear the serious problem of "maintaining the structure and not being able to maintain the solid contact structure of the adhesive film in the remaining area where the OLB pad was not formed."

However, when the present invention is achieved, in addition to the data OLB pads 1 on the edge surface of the lower panel 221, for example, the data lines 233, a plurality of fixing patterns 3 are further provided. Because it is formed, the firmness of the first adhesive film 30 is not only in the "region in which the OLB pads 1 for data are formed" in the production line, but also in the "region in which the OLB pads 1 for data are not formed". The contact structure can be maintained, and as a result, an effect of preventing peeling of the signal connection member 242 for data associated with the first adhesive film 30 can be obtained.

When one embodiment of the present invention is achieved, the production line can obtain the effect that the signal connection system of the liquid crystal display device to be finally shipped is normally maintained.

At this time, as shown in the figure, each of the fixing patterns 3 are disposed between each group of the OLB pads 1 for data arranged in groups, for example, and have a protrusion height of, for example, 10 μs to 5000 μs. .

In the present invention, when the OLB pads 1 for data are formed on the lower panel 221, the same masks are used to simultaneously form the respective fixing patterns 3 forming the gist of the present invention. In this case, since there is no need to proceed with a separate process for forming the fixing patterns 3 in the production line, it is possible to overcome the disadvantage that the overall process staff is increased.

Of course, in this case, since the fixing patterns 3 are made of a mask having the same shape as the data OLB pads 1, when the present invention is achieved, each of the fixing patterns 3 is, for example, an OLB for data. The same shape as the pads 1 is maintained.

On the other hand, in the display unit for a liquid crystal display device according to the present invention having the above-described configuration, first, when an image signal output from an external information processing apparatus, for example, a computer main body, is input to the data printed circuit board 240, the data is input. The printed circuit board 240 generates a data driving signal in response to the input image signal.

At this time, the data driving signal generated from the data printed circuit board 240 passes through the drive signal transmission patterns 243 of the data signal connecting member 242 and is then input to the data drive IC 246 for processing. do. In this case, the data drive signal input to the data drive IC 246 may be, for example, an STH (StarT Horizontal) signal or data for accurately latching color data output from the computer main body to the data drive IC 246. The load signal for outputting the data processed by the drive drive IC 246 to the data line 233 of the lower panel 221, the clock signal for transferring data, and the color data of each RGB And gradation voltages.

Thereafter, the processed data driving signal is quickly input to the data lines 233 of the lower panel 221 via the driving signal transmission patterns 243 again.

At this time, as described above, the first adhesive film 30 for fixing the data connection member 242 to the edge surface of the lower panel 221 may be “data for” by the action of the fixing patterns 3 described above. Not only in the "region in which the OLB pads 1 are formed", but also in the "region in which the OLB pads for data are not formed". It is possible to maintain a solid contact structure, as a result, the data signal connecting members 242 associated with the data lines 233 of the lower panel 221 via the first adhesive film 30 is the data described above The driving signal can be accurately transmitted to each of the data lines 233. As a result, in the production line, the effect of maintaining the signal connection system of the liquid crystal display device can be obtained.

Through the above-described process, when the data driving signal is input, the gate driving signal generated from the gate printed circuit board 260 passes through the driving signal transmission patterns 213 of the gate signal connecting member 214. After that, it is input to the gate drive IC 250 and processed. In this case, the gate driving signal input to the gate drive IC 250 may be a shift signal, a gate clock signal, an output allowable signal, a thin film transistor turn-on signal, a thin film transistor turn-off signal, or the like. Among these, the output permission signal is a signal that allows the gate drive IC 250 to output a signal processed by the gate drive IC 250 to the gate line 236 of the lower panel 221.

Subsequently, the processed gate driving signal is input to the gate lines 236 of the lower panel 221 via the driving signal transmission patterns 213 again, and according to the input of the gate driving signal, the lower panel 221. All of the thin film transistors in a row formed in a matrix form are rapidly turned on, and the gray scale voltage applied to the data lines is quickly output to the pixel electrode by the turn-on of the thin film transistor. As a result, an electric field is formed between the pixel electrode and the common electrode in proportion to the gray scale voltage.

Due to the formation of the electric field, the liquid crystal interposed between the upper panel 222 and the lower panel 221 is changed, and eventually, by changing the light transmittance output from the lamp 13, constant image information can be obtained. It will be displayed externally.

Meanwhile, as shown in FIG. 4, in another embodiment of the present invention, for example, a plurality of fixing patterns on the edges of the gate lines 236 of the lower panel 221 overlapping the second adhesive film 31. Protrude (4). In this case, the remaining area of the entire bottom surface of the gate lines 236 of the lower panel 221 where the gate OLB pad 2 is not formed is filled with a plurality of fixing patterns 4.

Each of the fixing patterns 4 is located on the outermost surface of the lower panel which can be in direct physical contact with the second adhesive film 31, for example, to form a natural anchor structure by its outer profile. Therefore, when the above-described second adhesive film 31 overlaps the edges of the gate lines 236 of the lower panel 221 in the state where the fixing patterns 4 are disposed in advance, the second adhesive film 31 can secure a more stable fixing base by the action of each of the fixing patterns (4).

When another embodiment of the present invention is achieved, in addition to the gate OLB pads 1 on the edges of the gate lines 236 of the lower panel 221, a plurality of fixing patterns 4 are further formed. In the production line, not only in the region in which the gate OLB pads 2 are formed, but also in the region in which the gate OLB pads are not formed, the firm contact structure of the second adhesive film 31 can be maintained. As a result, the peeling phenomenon of the gate signal connecting member 214 associated with the second adhesive film 31 may be prevented in advance.

Of course, even when this embodiment of the present invention is achieved, as in the above-described embodiment, the production line can obtain the effect of maintaining the signal connection system of the liquid crystal display device finally shipped.

In this case, as shown in the drawing, each of the fixing patterns 4 is disposed between each group of the OLB pads 2 for gates arranged in groups, for example, similarly to the above-described fixing patterns 3. For example, it has a protrusion height of 10 mm to 5000 mm.

In another embodiment of the present invention, similarly to the above-described embodiment, when the gate OLB pads 2 are formed in the lower panel 221, the same masks are used to simultaneously hold the respective fixed patterns 4. To form. In this case, since there is no need to proceed with a separate process for forming the fixing patterns 4 in the production line, it is possible to overcome the disadvantage that the overall process staff is increased. In this case, since the fixing patterns 4 are made of a mask having the same shape as the gate OLB pads 2, in the case where the present invention is achieved, each of the fixing patterns 4 is, for example, OLB pads for the gate. The same shape as (2) is maintained.

On the other hand, as shown in FIG. 5, in another embodiment of the present invention, the above-described fixing patterns 3 and 4 are disposed on the bottom surface and the gate lines 236 of the data lines 233 of the lower panel. At the same time, both edges are formed to protrude. In this case, the remaining area where the data OLB pad 1 is not formed among the entire edges of the data lines 233 of the lower panel 221 is filled with a plurality of fixing patterns 3. Out of the entire edges of the gate lines 236, the remaining regions where the gate OLB pads 2 are not formed are filled with a plurality of fixed patterns 4.

In another exemplary embodiment of the present invention, the fixed patterns 3 and 4 are formed on both of the bottom surface of the lower surface 221 of the data lines 233 and the bottom surface of the gate lines 236. Therefore, when another embodiment of the present invention is applied, the production line can obtain the advantage that can block the peeling of the first adhesive film 30 and the second adhesive film 31 at once.

As described above, in the present invention, a series of uneven pads are disposed in the "part area of the liquid crystal panel in which the OLB pad is not formed", whereby the adhesive film is not only in the "area where the OLB pad is formed" but also in the "OLB By inducing a stable support base even in an area where pads are not formed, it is possible to prevent unexpected peeling of the signal connection member connected to the adhesive film in advance.

This invention exhibits an overall useful effect in various electronic devices employing display units, such as notebook computers, desktop computers, electronic calculators, monitors, and the like.
