In general, a display module is an apparatus that displays an image, and utilization of the display module is not high since the rear of the display module is not seen through.

<CIT> refers to a liquid crystal display device includes a liquid crystal display panel and a backlight. The liquid crystal display device has a hole in the screen. The hole of the liquid crystal display panel has a first protecting member; and the hole of the backlight has a second protecting member. The liquid crystal display panel hole and the backlight hole form a common hole. The common hole has a third protecting member. With this structure, the viewer can see another display in the liquid crystal display screen without feeling a noticeable difference.

<CIT> refers to a liquid crystal display device includes a backlight device including at least a light guide plate and a light source disposed so as to face a light introduction part on an end surface of the light guide plate, and a liquid crystal display disposed on the light emitting surface side of the light guide plate of the backlight device, and has a light shielding member stuck to a peripheral edge of an aperture formed in the light guide plate. In the liquid crystal display device, the light shielding member is integrally constituted by a resin member and an elastic member having high light shielding property, and the resin member is made of a polycarbonate (PC), and the elastic member is made of an elastomer.

<CIT> refers to an irregular shape display having a hole, applying a cylinder-shaped guide member to a hole region to secure fasten ability between the guide member and a lower cover, thereby implementing a narrow bezel.

<CIT> refers to a lighting device includes LEDs, a light guide plate, and a frame. The light guide plate includes a light guide plate hole portion passing through in a thickness direction, a light entering surface, and a light exiting surface. The frame surrounds the light guide plate. The frame includes an outer peripheral wall portion and an inner peripheral wall portion. The outer peripheral wall portion opposes an outer peripheral end face of the light guide plate. The inner peripheral wall portion inserted to the light guide plate hole portion opposes an inner peripheral end face of the light guide plate on an inner side of the light guide plate hole portion. The inner peripheral wall portion has a configuration in which the opposing surface has a lower light reflectivity than that of an opposing surface of the outer peripheral wall portion.

<CIT> refers to a gaming machine includes a liquid crystal display having a liquid crystal panel and a light guiding plate placed at the rear of the liquid crystal panel and formed with a light deflection pattern for guiding light emitted from illumination means into the liquid crystal panel, and a variable display device placed at the rear of the liquid crystal display and having a plurality of reels provided in a row. Parts of the light guiding plate to which the reels are opposed are made light transmission areas. The light guiding plate is formed with a first light deflection pattern on the periphery of the light transmission areas and is formed with a second light deflection pattern in a portion more distant from the light transmission areas than the first light deflection pattern. The first light deflection pattern is denser than the second light deflection pattern.

<CIT> refers to a display device including a sub-backlight unit which can prevent the obscure sights caused by light from the light source of the sub-backlight unit arriving on an article or reel of the main display screen and then reflecting in the frontal direction is provided. The sub-backlight unit includes a second light guide panel having an opening part formed therein corresponding to a transparent window, a second light source disposed around the second light guide panel, and a polymer dispersed liquid crystal (PDLC) sheet disposed close to the front side of the opening of the second light guide panel.

In recent years, therefore, research and development on a display apparatus capable of simultaneously displaying a digital image formed by driving liquid crystals and a real object located opposite a liquid crystal panel on the same screen has been actively conducted.

As an example, a display configured such that a part of a screen is cut to allow an object disposed at the rear to be seen from the front is being developed.

In this case, a part of a backlight unit (BLU) disposed at the rear of a display panel must be cut. At this time, however, a light guide panel (LGP) configured to transfer light from a light source to the front must also be cut. As a result, a light transfer path is interrupted in a cutting area of the light guide panel, whereby light is not uniformly transferred to the front. That is, brightness of the cutting area and brightness around the cutting area become lower than brightness of the other areas. In particular, if a plurality of cutting areas is included, brightness between the cutting areas becomes much lower than brightness of the other areas. Furthermore, for a game machine using such a display (e.g. a reel game machine), a reel located at the rear of the display is seen through the cutting area, and the reel transmission area is relatively dark due to reduction in brightness, whereby it is difficult for a user to focus on a game.

In order to solve such a problem, conventional technology for forming a pattern on a light guide panel was developed. However, such conventional technology had problems in that expensive equipment is necessary and a complex processing procedure is performed.

It is an object of the present invention to provide a light guide panel according to claim <NUM>.

That is, the polarization portion <NUM> transmits only light that is vibrated in a predetermined direction, whereas the polarization transmission portion <NUM> is formed through a part of the polarization portion <NUM> such that all kinds of light are transmitted through the polarization transmission portion, whereby the rear of the display panel <NUM> is visible.

<FIG> is an exploded perspective view showing the display module according to the embodiment of the present invention. Referring to <FIG>, the display module according to the embodiment of the present invention is configured such that devices are attached to the front surface and a rear surface of the display panel <NUM>, wherein the polarization portion <NUM>, described with reference to <FIG>, is attached to the front surface of the display panel <NUM>, and a backlight unit <NUM> is attached to the rear surface of the display panel <NUM>.

The backlight unit <NUM> may include a light source, a diffuser panel <NUM>, a light guide panel <NUM>, and a back cover <NUM>.

The light source, the light guide panel <NUM>, and the diffuser panel <NUM> may be received in the back cover <NUM>, which may be formed so as to be open at a front surface thereof. In addition, the back cover <NUM> may be formed so as to have a size corresponding to the size of the display panel <NUM> such that the display panel <NUM> can also be received in the back cover, and a reflector panel configured to reflect light from the light source in a direction in which the display panel <NUM> is located may be installed at the back cover <NUM>.

The light source may be constituted as the result of a plurality of LEDs being mounted on a circuit board. The light source may be installed at the rear of the back cover <NUM> to provide light to the display panel <NUM> located at the front of the backlight unit <NUM>, or may be installed around the back cover <NUM> to provide light to the display panel <NUM> through the light guide panel <NUM>, a description of which will follow.

When the light source is installed around the back cover <NUM>, the light guide panel <NUM> may change the path of light generated by the light source in the direction in which the display panel <NUM> is located.

The light guide panel <NUM> may be formed so as to have a sheet shape, and may have a light guide pattern configured to change the path of light provided by the light source in the direction in which the display panel <NUM> is located.

The diffuser panel <NUM> may diffuse light provided by the light source and may provide the diffused light to the display panel <NUM>. To this end, the diffuser panel <NUM> diffuses light provided through the light guide panel <NUM> and provides the diffused light to the display panel <NUM>.

Meanwhile, each of the diffuser panel <NUM>, the light guide panel <NUM>, and the back cover <NUM>, which constitutes the backlight unit <NUM>, includes a plurality of cutting areas (backlight transmission portions <NUM>) such that the rear of the display panel <NUM> is visible, wherein the plurality of cutting areas is formed at the position corresponding to the polarization transmission portion <NUM> formed at the polarization portion <NUM>.

In order to solve a light blocking problem due to the plurality of cutting areas (backlight transmission portions <NUM>) and to uniformly transmit light provided by the light source to the display panel <NUM>, the light guide panel <NUM> may further include a predetermined member that reacts to light. That is, the predetermined member that reacts to light may be attached to each of inner surfaces of the plurality of cutting areas (backlight transmission portions <NUM>) formed in the light guide panel <NUM>. Examples in which the predetermined members are attached to the light guide panel <NUM> are illustrated in <FIG> and <FIG>.

<FIG> and <FIG> are perspective views respectively showing light guide panels according to first and second embodiments of the present invention. Referring to <FIG>, the light guide panel <NUM> according to the first embodiment of the present invention includes three backlight transmission portions <NUM>, <NUM>, and <NUM> arranged in a line, and a predetermined member <NUM> that reacts to light is attached to each of inner surfaces thereof.

When two or more backlight transmission portions <NUM>, <NUM>, and <NUM> are formed in the light guide panel <NUM>, as in the example of <FIG>, light radiated from the light source to the light guide panel <NUM> is blocked by the backlight transmission portions <NUM>, <NUM>, and <NUM>, whereby brightness of a transmission area of each of the backlight transmission portions <NUM>, <NUM>, and <NUM> and brightness of an area a1 between the backlight transmission portions <NUM>, <NUM>, and <NUM> become lower than brightness of the other areas. The predetermined member <NUM> is provided to solve the above problem.

To this end, the predetermined member <NUM>, which is a reflector, may be implemented by a tape, a sheet, or a film, and may be attached to at least one of the inner surfaces of the three backlight transmission portions <NUM>, <NUM>, and <NUM>. A coating solution having a color that reflects light may be applied to opposite surfaces of the predetermined member <NUM>. For example, a white coating solution may be applied to the opposite surfaces of the predetermined member <NUM>.

More preferably, a white reflector <NUM> having a white coating solution applied to opposite surfaces thereof is attached to left/right inner surfaces of each of the three backlight transmission portions <NUM>, <NUM>, and <NUM>, whereby it is possible to solve a problem in that brightness of the transmission area of each of the backlight transmission portions <NUM>, <NUM>, and <NUM> and brightness of the area a1 between the backlight transmission portions <NUM>, <NUM>, and <NUM> are lower than brightness of the other areas.

However, if the white reflector <NUM> having the white coating solution applied to opposite surfaces thereof is attached to the left/right inner surfaces of each of the three backlight transmission portions <NUM>, <NUM>, and <NUM>, as in the example of <FIG>, an outside area a2 of each of the backlight transmission portions <NUM> and <NUM> adjacent to left/right light emission portions may be excessively brightened.

In order to solve the above problem, no white reflector <NUM> may be attached to the inner surface, adjacent to the outside area a2, of each of the backlight transmission portions <NUM> and <NUM> adjacent to the left/right light emission portions, or a member having another property may be attached thereto.

<FIG> is a view illustrating the second embodiment of the present invention, which solves the above problem. Referring to <FIG>, the light guide panel <NUM> according to the second embodiment of the present invention includes three backlight transmission portions <NUM>, <NUM>, and <NUM> arranged in a line, and first and second members <NUM> and <NUM> that react to light are optionally attached to each of inner surfaces thereof.

The first and second members <NUM> and <NUM> are members having different properties in which the first and second members react to light, wherein the first member <NUM> has a property in which both surfaces of the first member reflect light and the second member <NUM> has a property in which one surface of the second member reflects light and the other surface of the second member offsets the reflected light. To this end, the first member <NUM> may be a first reflector having a coating solution having a color that reflects light (e.g. white) applied to opposite surfaces thereof, and the second member <NUM> may be a second reflector having a coating solution having a color that reflects light (e.g. white) applied to one surface thereof and a coating solution having a color that offsets light (e.g. gray) applied to the other surface thereof. In addition, each of the first member <NUM> and the second member <NUM> may be implemented by a gray tape, a gray sheet, or a gray film.

In order to solve a problem in that brightness of a transmission area of each of the backlight transmission portions <NUM>, <NUM>, and <NUM> and brightness of an area a1 between the backlight transmission portions <NUM>, <NUM>, and <NUM> become lower than brightness of the other areas, the first member <NUM> reflects light. In order to solve a problem in that an outside area a2 of each of the backlight transmission portions <NUM> and <NUM> adjacent to the left/right light emission portions is excessively brightened, the second member <NUM> reflects light to the transmission area of each of the backlight transmission portions <NUM> and <NUM> and offsets light reflected to the outside area a2.

To this end, the first member <NUM> may be attached to an inner surface of each of the backlight transmission portions <NUM>, <NUM>, and <NUM> adjacent to the area a1 between the backlight transmission portions <NUM>, <NUM>, and <NUM>, and the second member <NUM> is attached to the inner surface of each of the backlight transmission portions <NUM> and <NUM> adjacent to the outside area a2. At this time, the second member <NUM> is attached such that one surface of the second member having a coating solution having a color that reflects light (e.g. white) applied thereto faces the transmission area of each of the backlight transmission portions <NUM> and <NUM> and the other surface of the second member having a coating solution having a color that offsets light (e.g. gray) applied thereto faces the outside area a2.

<FIG> are views illustrating use examples of display modules having the light guide panels according to the first and second embodiments of the present invention. An example in which the operation state of a reel game machine is displayed when the reel game machine is located at the rear of each of the display modules having the light guide panels according to the first and second embodiments of the present invention applied thereto will be described while comparing with a conventional case.

<FIG> shows a use example of a display module <NUM>' having a conventional light guide panel. Referring to <FIG>, it can be seen that, for the conventional display module <NUM>' having three transmission portions <NUM>', <NUM>', and <NUM>', an area a1' between the transmission portions <NUM>', <NUM>', and <NUM>' is darker than other areas.

<FIG> is a view showing a use example of a display module <NUM>' having the light guide panel illustrated in <FIG> applied thereto. Referring to <FIG> and <FIG>, it can be seen that, when the predetermined member <NUM> is attached to at least one of the inner surfaces of the backlight transmission portions <NUM>, <NUM>, and <NUM> formed in the light guide panel <NUM>, wherein the predetermined member <NUM> is attached to both the left/right inner surfaces of each of the backlight transmission portions <NUM>, <NUM>, and <NUM>, as in the first embodiment of the present invention, display areas <NUM>', <NUM>', and <NUM>' configured to display the operation state of the reel game machine located at the rear of the display module <NUM>' and areas a1' and a2' around the display areas <NUM>', <NUM>', and <NUM>' are not darker than the other areas. In the first embodiment of the present invention, as described above, it is possible to solve a problem in that brightness of the screen around the cutting areas is reduced as the result of cutting a part of the light guide panel <NUM>.

In this case, however, it can be seen that the left/right areas a2' of the display areas <NUM>', <NUM>', and <NUM>' (i.e. the left side of the display area <NUM>' and the right side of the display area <NUM>') are excessively brightened.

<FIG>, which is a view showing a use example of a display module capable of solving the problem in that the excessively brightened areas are generated, as described above, shows a use example of a display module <NUM>' having the light guide panel illustrated in <FIG> applied thereto. Referring to <FIG> and <FIG>, it can be seen that, when the first and second members <NUM> and <NUM> having different properties in which the first and second members react to light are attached to the inner surface of each of the backlight transmission portions <NUM>, <NUM>, and <NUM> formed in the light guide panel <NUM>, wherein the first member <NUM> having a property in which both surfaces of the first member reflect light is attached to the area a1 between the backlight transmission portions <NUM>, <NUM>, and <NUM> and the second member <NUM> having a property in which one surface of the second member reflects light and the other surface of the second member offsets the reflected light is attached to the outside area a2 of each of the backlight transmission portions <NUM> and <NUM> adjacent to the left/right light emission portions, brightness of the left/right areas a2' of the display areas <NUM>', <NUM>', and <NUM>' configured to display the operation state of the reel game machine located at the rear of the display module <NUM>' (i.e. the left side of the display area <NUM>' and the right side of the display area <NUM>') is similar to brightness of the other areas. In the second embodiment of the present invention as claimed in claim <NUM>, as described above, it is possible to solve a problem that may occur when the first embodiment of the present invention is applied, i.e. a problem in that a specific area is excessively brightened.

<FIG> is a perspective view showing a light guide panel according to a third embodiment of the present invention.

In order to solve a problem in that brightness of a transmission area of each of the backlight transmission portions <NUM>, <NUM>, and <NUM> and brightness of an area a1 between the backlight transmission portions <NUM>, <NUM>, and <NUM> become lower than brightness of the other areas, the first member <NUM> reflects light. In order to solve a problem in that an outside area a2 of each of the backlight transmission portions <NUM> and <NUM> adjacent to the left/right light emission portions is excessively brightened, the second member <NUM> reflects light to the transmission area of each of the backlight transmission portions <NUM> and <NUM> and offsets light reflected to the outside area a2. Also, in order to remove a hot spot generated at an adjacent area a3 through which, during a process in which light emitted from a light emission portion provided outside the light guide panel (particularly, under the light guide panel) is transmitted, the light is transmitted, the third member <NUM> diffuses the light.

At this time, the third member <NUM> may be implemented by a diffuser sheet configured to diffuse light.

Meanwhile, in <FIG>, an example in which the third member <NUM> is attached to a lower part of each of the inner surfaces of the backlight transmission portions <NUM>, <NUM>, and <NUM> is shown; however, the attachment position of the third member <NUM> is not limited to the position illustrated in <FIG>. That is, the third member <NUM> is attached to an inner surface adjacent to the position at which the hot spot is generated. When the hot spot is generated at an upper part of each of the backlight transmission portions <NUM>, <NUM>, and <NUM>, the third member <NUM> may be attached to the upper part of each of the backlight transmission portions <NUM>, <NUM>, and <NUM>.

In addition, the inner surface adjacent to the position at which the hot spot is generated may be etched, without attachment of a separate member, in order to remove the hot spot. In this case, it is possible to obtain the same effect.

<FIG> are views illustrating use examples of a display module having the light guide panel according to the third embodiment of the present invention.

<FIG>, which is a view showing a use example of the display module from which the hot spot has been removed, shows a use example of a display module <NUM>' having the light guide panel illustrated in <FIG> applied thereto. Referring to <FIG> and <FIG>, it can be seen that, when the third member <NUM> is attached to the lower part of each of the inner surfaces of the backlight transmission portions <NUM>, <NUM>, and <NUM> or the lower part is etched, as in the third embodiment of the present invention shown in <FIG>, it is possible to remove the hot spot.

<FIG> is a schematic perspective view showing a game machine having a display module having transmission portions according to an embodiment of the present invention. Referring to <FIG>, the game machine <NUM> according to the embodiment of the present invention includes a display module <NUM> having transmission portions and a real game unit <NUM> configured to execute a game.

The real game unit <NUM> may be moved according to mechanical operation in order to execute the game.

In <FIG>, the case in which the real game unit <NUM> is a reel unit of a reel game machine is shown; however, the real game unit <NUM> may be implemented in various forms capable of executing the game.

The real game unit <NUM> may be may be located at the rear of the display module <NUM> including the plurality of transmission portions <NUM> such that, when a gamer looks at the display module <NUM>, the real game unit is visible through the transmission portions <NUM>. Consequently, the gamer may play the game using an image displayed on the display module <NUM> and the real game unit <NUM> seen through the transmission portions <NUM>.

The game machine <NUM> having the display module <NUM> having the transmission portions <NUM> according to the embodiment of the present invention may include a manipulation mechanism.
