The present invention relates to an image display module for an information processing apparatus, and more particularly, to improve the edge shape of a top chassis and to buffer contact shocks transmitted from the top chassis to the polarizing plate, thereby damaging the polarizing plate due to contact with the top chassis. The present invention relates to an image display module for an information processing apparatus which can prevent the occurrence of a defect in advance.

Recently, information processing devices such as notebook computers, desktop computers, and the like, which process various information quickly according to the development of the information industry, are also rapidly developing.

In particular, among these information processing devices, notebook computers have emerged as the most popular information processing devices due to their thinness and miniaturization.

In general, as an image display module mounted in a notebook computer, a liquid crystal display module using the physical and optical characteristics of the liquid crystal is widely adopted, which is smaller, lighter, and smaller than the conventional CRT (Cathode Ray Tube). This is because it has the advantages of low power consumption, and this advantage exactly matches the characteristics of the notebook computer whose main field of use is 'portable'.

In recent years, the size of such an image display module such as a liquid crystal display module has gradually increased to a size of, for example, 13.3 inches or more according to a user's request, and accordingly, the cover of a notebook computer for mounting the image display module is correspondingly. The case is also getting bigger.

In general, a conventional image display module, for example, a liquid crystal display module, has a structure in which a TFT substrate and a color filter substrate are sequentially stacked via a liquid crystal, and a tape automated bonding (TAB) having a semiconductor chip is mounted on the TFT substrate. It is attached through (Anisotropic Conductive Film) to connect PCB (Printed Circuit Board) and TFT board.

Here, for example, a polarizing plate is generally attached to the color filter substrate, and the polarizing plate selectively transmits only light that vibrates strongly in a specific direction among the light passing through the liquid crystal to the outside, thereby allowing the liquid crystal display device to attach itself to the color filter substrate. Assist in performing the assigned information display function well.

Various forms of polarizers according to the prior art are described, for example, in US Patent Publication No. 5486935, "High efficiency chiral nematic liquid crystal rear polarizer for liquid crystal display devices having a notch polarization of 100 nm to 250 nm bandwidth. for liquid crystal display having a notch polarization bandwidth of 100nm to 250nm ", US Patent No. 5548422" Notch filters with cholesteric polarizers with birefringent film and linear polarizer ", US Patent No. 5691788" LCD having a polarization or diffusion plate with an irregularly coated first opaque material and a black matrix coated irregularly with a second opaque material an irregularly coated first opaque material and black matrix of a second opaque material " It is.

However, these conventional image display modules for information processing apparatus have some serious problems.

As described above, in the structure of a conventional image display module, for example, a liquid crystal display module, for example, a polarizing plate is attached to the color filter substrate to polarize light passing through the liquid crystal in a predetermined direction and selectively transmit it externally. The polarizing plate forms a structure in which the main structures constituting the liquid crystal display module, for example, a color filter substrate, a TFT substrate, a printed circuit board, a lamp, a light guide plate, and the like are enclosed in a storage space of a mold frame and are surrounded by a top chassis.

At this time, since the polarizing plate has a structure attached to the color filter substrate disposed at the top of the module, for example, when the assembly of the liquid crystal display module is finally completed, the polarizing plate has a border and firmness of the top chassis surrounding the color filter substrate. It makes a structure that comes in contact.

However, since the top chassis in contact with the polarizing plate is made of a metal material such as stainless, for example, in order to maintain the reinforcing function imparted to the polarizing plate for a long time, when the contact between the polarizing plate and the top chassis proceeds for a long time, the polarizing plate is in the top chassis. Scratching causes a "scratch phenomenon" at the contact with the top chassis.

Due to this "scratch phenomenon", the surface of the polarizing plate is greatly damaged, and as a result, the polarizing plate cannot smoothly perform the polarizing function imparted to itself.

As such, when the polarizing plate cannot perform its function, the image display module employing the polarizing plate also cannot perform the smooth image information display function.

Accordingly, an object of the present invention is to prevent the "scratch phenomenon" of the polarizing plate due to contact with the top chassis in advance by performing a predetermined shape improvement on a predetermined portion of the top chassis in contact with the polarizing plate.

Another object of the present invention is to prevent damage to the polarizing plate due to the "scratch phenomenon" in advance, so that the polarizing plate can normally perform the function assigned to it.

Still another object of the present invention is to ensure a smooth image information display function of an image display module employing the same by maintaining the function of the polarizing plate normally.

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

The present invention for achieving the above object is a rectangular ring-shaped mold frame for receiving the lamp, the light guide plate and the sheet, and the upper panel is accommodated in the mold frame, the upper panel is attached to the uppermost, liquid crystal in the upper panel An image panel assembly including a lower panel coupled through an interposed lower panel, a gate PCB electrically connected to one side of the lower panel, and a source PCB electrically connected to the other side of the lower panel; And a top chassis that contacts and defines an effective display area of the image panel assembly. At this time, the edge of the top chassis in contact with the polarizing plate is formed in a round shape so that the contact shock transmitted from the top chassis to the polarizing plate can be buffered. In another example of the present invention, a buffer structure that buffers the contact shock transmitted from the top chassis to the polarizer is further mounted on the edge of the top chassis in contact with the polarizer.

When the present invention is achieved, the polarizing plate does not cause a "scratch phenomenon" due to the impact of contact with the top chassis, and eventually, the image display module employing this polarizing plate normally performs the image information display function granted to itself. It can be done.

Hereinafter, an image display module for an information processing apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the image display module 100 for an information processing apparatus according to the present invention has a structure in which a mold frame 20, an image panel assembly 37, and a top chassis 50 are combined with each other. .

In this case, the mold frame 20 has a rectangular ring shape, for example, to define an accommodating area in which the reflective plate (not shown), the light guide plate 10, and sheets (not shown) are stacked. Here, for example, a lamp 70 having a light irradiation function is stored at the upper edge in the longitudinal direction.

In this case, a gate PCB accommodating part 22 is formed at a predetermined portion of the accommodating area, for example, a unidirectional left edge, and the gate PCB accommodating part 22 is surrounded by sidewalls and separated by partition walls. It is composed of Each of the windows forms a constant depth by the heights of the sidewalls and the partition wall, so that the devices mounted on the gate PCB to be described later can be more stably received.

In addition, a source PCB accommodating portion 21 for accommodating a source PCB, which will be described later, is formed at another predetermined portion of the accommodating area, for example, the longitudinal lower edge, and the source PCB accommodating portion 21 is a source PCB. Thus, for example, when bent 180 ° back to the back of the mold frame 20, it provides a stable storage space thereof. Since the source PCB accommodating portion 21 has a constant depth, the elements mounted on the source PCB to be described later can be more stably received.

On the other hand, the image panel assembly 37 is the image panel 30 consisting of the upper panel 32 and the lower panel 31 stacked largely via the liquid crystal, and the connection line for the data line of the lower panel 31 ( And a gate PCB 36 connected to a connection pad (not shown) for a gate line. At this time, the upper panel 32 of the image panel 30 selectively collects only the light vibrating strongly in a specific direction among the light emitted from the lamp 70 and transmitted through the liquid crystal to transmit the light to the outside. 60 is attached. The polarizing plate 60 is also attached to the lower panel 31 of the image panel 30, for example. Thereafter, when a series of assembling processes are all completed, the above-described parts are stably stored in the storage space of the mold frame 20.

In this case, the gate PCB 36 is electrically connected to the gate line of the lower panel 31 through the TCP 35 mounted with the driving IC (not shown). In this case, the driving IC is attached to the front surface of the TCP 35, and the gate PCB 36 maintains a narrow gap with the lower panel 31 as a whole to prevent its flow. Of course, such a gate PCB 36 is stably stored in the above-described gate PCB accommodating portion 22.

In addition, the source PCB 34 is electrically connected to the source line of the lower panel 31 through the TCP 33 on which the driving IC is mounted. Here, in the case of the source PCB 34, the driving IC is attached to the back of the TCP 33 when viewed from the front of the figure. This is for stably storing the driving IC at the rear of the mold frame 20 when the source PCB 34 itself is rotated by 180 ° and fixed to the source PCB accommodating portion 21 of the mold frame 20. . Of course, in order for the source PCB 34 to rotate smoothly, sufficient space for rotation between the lower panel 31 and the source PCB 34 should be secured.

In the above description, an example in which the source PCB 34 is rotated 180 ° and accommodated in the source PCB accommodating portion 21 of the mold frame 20 has been mainly described. Similarly, the gate PCB 36 is also rotated 180 °. Thus, it may be stored in the gate PCB accommodating portion 22. Of course, in this case, the drive IC attached to the gate PCB 36 is attached to the rear side of the TCP 35 when viewed from the front of the figure.

On the other hand, as shown in the figure, the top chassis 50 coupled to the upper portion of the above-described mold frame 20 to surround its edge has a rectangular container shape with a window formed on the front surface, for example, a material such as stainless steel. Is made of. In this case, the size of the window is formed to correspond to the effective display area of the image panel assembly 37. In addition, the side wall extends 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 large enough to wrap the above-described mold frame 20.

At this time, as shown in Figure 2, the edge 51 of the top chassis 50 in contact with the polarizing plate 60 is formed in a round shape. As such, when the edge 51 of the top chassis 50 maintains a round shape, the contact shock transmitted from the top chassis 50 to the polarizing plate 60 may be due to the structural characteristics of the top chassis edge 51. In this way, a stable buffering operation may be performed without being directly transmitted to the polarizing plate 60. In this case, even if the contact with the top chassis 50 proceeds for a long time, the polarizing plate 60 does not cause a "scratch phenomenon", and eventually, the polarizing plate 60 can perform the polarization function given to the user smoothly. .

When the present invention is achieved and the polarizing plate 60 can smoothly perform the polarization function assigned to the present invention, the image display module 100 employing the polarizing plate 60 can also perform a smooth image information display function.

On the other hand, as shown in Figure 3, according to another embodiment of the present invention, the edge 51 of the top chassis 50, the buffer structure 52, for example, poly to buffer the shock of contact with the polarizing plate 60 Mid protective film is installed. As such, when the buffer structure 52 is mounted on the edge 51 of the top chassis 50, the contact shock transmitted from the top chassis 50 to the polarizer 60 is the edge 51 of the top chassis 50. By the action of the shock absorbing structure 52 mounted on the polarizing plate 60 can be performed without a certain buffering action. In this case, even if the contact with the top chassis 50 proceeds for a long time, the polarizing plate 60 does not cause a "scratch phenomenon" as in the above-described embodiment, and eventually, the polarizing plate 50 has a polarization function given to the polarizing plate 60. You can do it smoothly.

Moreover, in the case of this embodiment of the present invention, unlike the above-described embodiment, since the direct contact between the top chassis rim 51 and the polarizing plate 60 is blocked in advance due to the interposition of the buffer structure 52, the present invention If another embodiment of the is applied, there is no need in the production line to improve the shape of the top chassis rim 51 to round shape. As a result, when another embodiment of the present invention is applied, since the operation of changing the edge 51 of the top chassis 50 into a round shape can be omitted, the effect of improving the overall production efficiency can be obtained.

As described above, in the present invention, by improving the edge shape of the top chassis and buffering the contact shock transmitted from the top chassis to the polarizing plate, damage to the polarizing plate due to contact with the top chassis can be prevented in advance.

The present invention exhibits an overall useful effect in all kinds of information processing apparatuses employing image display modules, such as notebook computers, desktop computers, TVs, electronic calculators, digital cameras, and the like.

And while certain embodiments of the invention have been described and illustrated, it will be apparent that the invention may be embodied in various modifications by those skilled in the art.

Such modified embodiments should not be understood individually from the technical spirit or point of view of the present invention and such modified embodiments should fall within the scope of the appended claims of the present invention.

As described in detail above, in the image display module for an information processing apparatus according to the present invention, the edge of the top chassis in contact with the polarizing plate is improved in a round shape, or the polyimide protective film is formed on the edge of the top chassis in contact with the polarizing plate. Install a shock absorbing structure such as

In this case, the contact shock transmitted from the top chassis to the polarizing plate is not directly transmitted to the polarizing plate due to the action of the "round edge", "buffer structure", and the like. Latch phenomenon ”, and eventually, the image display module employing the polarizing plate of the present invention can normally perform the image information display function assigned to it.
