Description

Multi-layer liquid crystal display device, liquid crystal display device, single-layer liquid crystal display device, and device with display function

The present invention relates to a multilayer liquid crystal display device and the like.

Currently, liquid crystal display devices are installed in various devices. For example, a liquid crystal display device is mounted on a game machine (game machine or the like installed in a game center) or a game machine (slot machine or pachinko machine), and a desired content image is displayed on the liquid crystal display device. This enhances the sense of reality and enhances the fun of games and games.

Conventionally, a single liquid crystal panel has been used for this type of liquid crystal display device. For this reason, the display image becomes a two-dimensional image, and it has been necessary to devise such as wearing dedicated glasses in order to give the display a stereoscopic effect. On the other hand, recently, a configuration in which a plurality of liquid crystal panels are arranged in the depth direction to give a sense of depth to the display image is being adopted. Here, different images are displayed on the respective liquid crystal panels, and the images of the respective liquid crystal panels are synthesized by the viewer. In this way, a sense of depth is given to the composite image by moving the image arrangement back and forth. Further, the visual effect can be made different by devising an image displayed on each liquid crystal panel.

An example of this type of device is disclosed in Patent Document 1. According to this prior art, a plurality of screens each reproducing an image are arranged in parallel with a distance adjusted in advance. This distance is typically a quarter of the length of the front screen, but the actual distance can be varied to suit the desired effect.

Further, the present applicant discloses a specific configuration for changing the distance between screens in Patent Document 2, and a novel liquid crystal display device capable of adjusting the stereoscopic effect of an image displayed in multiple layers, and the same A configuration for providing a device with a display function equipped with is disclosed.

FIG. 1 shows a schematic exploded perspective view of a multilayer liquid crystal display device and a single layer liquid crystal display device according to an embodiment of the present invention. A multilayer liquid crystal display device 10 shown in FIG. 1 includes a first liquid crystal panel unit 11, a spacer 12, a second liquid crystal panel unit 13, and a light emitting unit (backlight) 14 in order from the front side to the back side.

FIG. 2 shows a more detailed configuration of the first liquid crystal panel unit 11 and the second liquid crystal panel unit 13. The first liquid crystal panel unit 11 includes a liquid crystal panel 11A and a support frame 11B that supports the liquid crystal panel 11A. The support frame 11B has a rectangular plate-like appearance and is open on the inside, and has a support groove 11C for supporting the liquid crystal panel 11A in front of the inside. The opening area 11W surrounded by the inner edge of the supporting groove 11C is substantially the same size as the display area 11D (shaded portion) of the liquid crystal panel 11A.

The second liquid crystal panel unit 13 is also composed of a liquid crystal panel 13A, a liquid crystal panel 13A, and a support frame 13B that supports the liquid crystal panel 13A, and the configuration is the same as that of the first liquid crystal panel unit 11 described above. Further, the size of the main surface and the size of the display areas (11D, 13D) provided on the main surface are substantially the same between the first liquid crystal panel unit 11 and the second liquid crystal panel unit 13.

The spacer 12 is a frame body having a rectangular plate appearance and opened on the inner side, and the size of the main surface substantially matches the size of the main surface of the first liquid crystal panel unit 11 and the second liquid crystal panel unit 13. The thickness of the spacer 12 defines the distance between the first liquid crystal panel unit 11 and the second liquid crystal panel unit 13 and is appropriately changed according to a desired visual effect.

Specifically, for example, when emphasizing the feeling of depth and popping out of the display content, the thickness of the spacer 12 may be increased so that the display screen of the second liquid crystal panel unit 13 is displayed more deeply (for example, An object is displayed on the first liquid crystal panel unit 11, and a background is displayed on the second liquid crystal panel unit 13). In addition, when emphasizing natural three-dimensionality and continuity of display images before and after, the thickness of the spacer 12 is reduced, and images displayed on the display surfaces of the first liquid crystal panel unit 11 and the second liquid crystal panel unit 13 are displayed. It is only necessary to adjust and give a three-dimensional feeling without a sense of incongruity in a predetermined viewing range (left and right, up and down) (for example, the first liquid crystal panel unit 11 is provided on the front side and the rear side when one object is cut in the front-rear direction, respectively) And the like are displayed on the second liquid crystal panel unit 13). Furthermore, when it is desired to use either of the above display effects, the spacer 12 may be selected to have an intermediate thickness.

The light-emitting unit (backlight) 14 serving as a light source for the first liquid crystal panel unit 11 and the second liquid crystal panel unit 13 has a rectangular plate shape in appearance. The light emitting unit 14 includes a light guide plate, a reflection sheet disposed on the back surface of the light guide plate, a light emitter that makes light incident on the light guide plate, a diffuser plate that diffuses light, and a frame body 14A that houses them. As for the illuminant, an illuminant having an optimal cost and function for illuminating the liquid crystal panel with a desired brightness may be adopted. For example, an illuminant such as CCFL (cold cathode tube) or LED (light emitting diode) or the like. Can be used in combination.

The size of the main surface of the light emitting unit 14 is substantially the same as the size of the main surface of the first liquid crystal panel unit 11 and the second liquid crystal panel unit 13, and the size of the light emitting region provided on the main surface of the light emitting unit 14 is The size substantially coincides with the size of the display areas (11D, 13D) provided on the main surfaces of the first liquid crystal panel unit 11 and the second liquid crystal panel unit 13.

FIG. 9A shows a configuration example of the light emitting unit 14. The light emitting unit 14 illustrated in FIG. 9A includes a frame body 14A, LEDs 14B, a reflection sheet 14C, a light guide plate 14D, and a diffusion plate 14E. LEDs 14B are provided as light emitters on the inner left and right side surfaces of the frame body 14A. Then, the reflection sheet 14C, the light guide plate 14D, and the diffusion plate 14E are accommodated in the frame body 14A. The reflection sheet 14C is disposed on the back side of the light guide plate 14D (when viewed from the observer), and the diffusion plate 14E is disposed on the front side of the light guide plate 14D (when viewed from the observer). The light emitted from the left LED 14B enters the light guide plate 14D from the left side surface of the light guide plate 14D, is extracted from the front side of the light guide plate 14D, and is diffused by the diffusion plate 14E. The light emitted from the right LED 14B enters the light guide plate 14D from the right side surface of the light guide plate 14D, is taken out from the front side of the light guide plate 14D, and is diffused by the diffusion plate 14E.

In FIG. 1, the first liquid crystal panel unit 11, the spacer 12, the second liquid crystal panel unit 13, and the light emitting unit 14 are illustrated with substantially the same thickness. However, if the desired function is satisfied, the respective thicknesses are not necessarily limited. It doesn't have to be the same. In general, a liquid crystal display device is required to be as thin as possible. Therefore, each liquid crystal display device may be the thinnest one having a thickness sufficient to realize a desired function.

The first liquid crystal panel unit 11, the spacer 12, the second liquid crystal panel unit 13, and the light emitting unit 14 can be easily separated from each other (details will be described later). For example, the separated first liquid crystal panel unit 11 and light emitting unit 14 are separated. 10A of 1st single layer liquid crystal display devices can be comprised combining these. In this case, the second single-layer liquid crystal display device 10B can be configured by combining the separated second liquid crystal panel unit 13 and a separately prepared light emitting unit 14 '. When the separated second liquid crystal panel unit 13 and the light emitting unit 14 are combined, the separated first liquid crystal panel unit 11 may be combined with a separately prepared light emitting unit 14 '.

The multi-layer liquid crystal display device 10 having the above configuration has the following features. For example, it is assumed that a gaming machine manufacturer who has a large inventory of the multilayer liquid crystal display device 10 is suddenly required to deliver a single layer liquid crystal display device. Conventionally, a gaming machine manufacturer had to order a new single-layer liquid crystal display device from a liquid crystal display device manufacturer. However, since the liquid crystal panel portion constituting the liquid crystal display device is expensive and may be thin, there are cases where the lead time from ordering to delivery becomes long. However, in the present invention, since the multilayer liquid crystal display device 10 can be easily disassembled, the liquid crystal panel included in the multilayer liquid crystal display device 10 can be used for a single-layer liquid crystal display device. As a result, the lead time can be shortened even when the liquid crystal panel is in short supply. In addition, it is also possible for a gaming machine manufacturer to disassemble a multi-layer liquid crystal display device in stock and manufacture a single-layer liquid crystal display device at a lower cost than creating a new single-layer liquid crystal display device. Bring merit.

In the first single-layer liquid crystal display device 10A, the first liquid crystal panel unit 11 and the light-emitting unit 14 can be easily separated. In the second single-layer liquid crystal display device 10B, the second liquid crystal panel unit 13 and the light-emitting unit 14 are easily separated. Can be separated. The separated first liquid crystal panel unit 11, second liquid crystal panel unit 13, light emitting unit 14, and separately prepared spacer 12 can be combined to form the multilayer liquid crystal display device 10.

This has the following features. For example, it is assumed that a gaming machine maker who has a large inventory of single-layer liquid crystal display devices suddenly needs to deliver multilayer liquid crystal display devices. Conventionally, a gaming machine manufacturer had to order a new multilayer liquid crystal display device from a liquid crystal display device manufacturer. However, when the liquid crystal panel portion is in short supply (as in the case of delivery of the single-layer liquid crystal display device described above), the lead time becomes long. However, in the above configuration, the single-layer liquid crystal display device (the liquid crystal panel portion and the light-emitting unit) can be easily disassembled, and the liquid crystal panel can be manufactured by diverting the liquid crystal panel and the light-emitting unit. Lead time can be shortened under the following conditions. Also, it is advantageous for game machine manufacturers in that it is possible to disassemble a single-layer liquid crystal display device in stock and manufacture a multi-layer liquid crystal display device at a lower cost than creating a new multi-layer liquid crystal display device. Bring.

Here, various combinations of the type of the liquid crystal panel 11A (FIG. 2) of the first liquid crystal panel unit 11 and the type of the liquid crystal panel 13A (FIG. 2) of the second liquid crystal panel unit 13 can be adopted. For example, both the liquid crystal panel 11A and the liquid crystal panel 13A may be transmissive liquid crystal panels. Further, the liquid crystal panel 11A may be a transmissive liquid crystal panel, and the liquid crystal panel 13A may be a transflective liquid crystal panel. By using a transflective liquid crystal panel, external light and light from the light emitting unit 14 can be used for displaying an image.

Furthermore, the liquid crystal panel 11A may be a transmissive liquid crystal panel, and the liquid crystal panel 13A may be a reflective liquid crystal panel. However, in this case, the light emitting unit 14 is unnecessary in the multilayer liquid crystal display device 10. When the multi-layer liquid crystal display device 10 is disassembled, the second liquid crystal panel unit 13 having a reflective liquid crystal panel can constitute a single-layer liquid crystal display device alone, and the first liquid crystal panel unit 11 having a transmissive liquid crystal panel is a light emitting unit. Are combined to form a single-layer liquid crystal display device.

Also, a so-called donut liquid crystal may be adopted. A multilayer liquid crystal display device 10D in such a case is shown in FIG. The multilayer liquid crystal display device 10 </ b> D includes a first liquid crystal panel unit 11, a spacer 12, a second liquid crystal panel unit 13, and a light emitting unit 34. Here, the first liquid crystal panel unit 11, the spacer 12, and the second liquid crystal panel unit 13 have the same configuration as the multilayer liquid crystal display device 10 of FIG. On the other hand, the light emitting unit 34 is different from the light emitting unit 14 of the multilayer liquid crystal display device 10. One configuration example of the light emitting unit 34 is shown in FIG. 9B. The light emitting unit 34 shown in FIG. 9B includes a frame 34A, LEDs 34B, a reflection sheet 34C, a light guide plate 34D, and a diffusion plate 34E. LEDs 34B are provided as light emitters on the inner left and right sides of the frame 34A. Then, the reflection sheet 34C, the light guide plate 34D, and the diffusion plate 34E are housed in this order in the frame 34A. The reflection sheet 34C is disposed on the back side when viewed from the observer, and the diffusion plate 34E is disposed on the front side when viewed from the observer. The In addition, the reflection sheet 34C, the light guide plate 34D, and the diffusion plate 34E have openings 34C1, 34D1, and 34E1, respectively, at corresponding positions. The light emitted from the LED 34B of the light emitting unit 34 does not pass through the openings 34C1, 34D1, and 34E1 of the reflection sheet 34C, the light guide plate 34D, and the diffusion plate 34E, but passes through the portions other than the openings, and the second liquid crystal panel unit 13, It goes to the spacer 12 and the first liquid crystal panel unit 11. When the reel rotating device is installed at the rear center portion of the light emitting unit 34 (reflective sheet 34C), the observer can pass through the transmissive second liquid crystal panel unit 13 and the first liquid crystal panel unit 11 (to say, through the glass). The reel rotation is visible. Further, an image is displayed in the area around the reel. That is, in the multi-layer liquid crystal display device 10D, the light emitting unit 34 is actually in a donut shape with an opening in the center, and the first liquid crystal panel portion 11 and the second liquid crystal panel portion 13 are in a donut shape. Although there is no reel, a reel is displayed at the center and an image is displayed on the periphery of the reel, so that it looks as if it is a donut-shaped liquid crystal display device for the observer. This is the reason why it is called donut liquid crystal. Of the reflective sheet 34C, the light guide plate 34D, and the diffuser plate 34E, the diffuser plate 34E functions as a so-called donut liquid crystal without providing an opening at the center.

At this time, if the multi-layer liquid crystal display device 10D is disassembled and, for example, the separated first liquid crystal panel unit 11 and the light emitting unit 34 are combined, a single-layer liquid crystal display device 10D ′ that is a donut liquid crystal can be configured (FIG. 3). . In this case, the separated second liquid crystal panel unit 13 may be combined with a normal light emitting unit 14 separately prepared to constitute a single-layer liquid crystal display device 10B (FIG. 3).

Alternatively, the spacer 12 may be provided with a shutter member, and the multilayer liquid crystal display device 10 may be configured as a so-called shutter liquid crystal. The shutter member is a plate-like member and can switch between diffusion and non-diffusion of transmitted light. When the light transmitted through the shutter member is diffused, the image of the second liquid crystal panel unit 13 is not displayed, and only the image of the first liquid crystal panel unit 11 is displayed. On the other hand, when the light transmitted through the shutter member is not diffused, the image of the second liquid crystal panel unit and the image of the first liquid crystal panel 11 are combined and displayed. In this way, images can be switched.

Also, the first liquid crystal panel unit 11 and the second liquid crystal panel unit 13 can be optically the same type by disposing a polarizing plate or a polarizing sheet that adjusts the optical axis between them. In this case, the same item can simply be ordered in double units, and generally the effect of reducing the purchase cost is increased.

Next, a configuration that allows the multi-layer liquid crystal display device 10, the first single-layer liquid crystal display device 10A, and the second single-layer liquid crystal display device 10B to be easily disassembled will be described.

It is concluded. As a result, the first liquid crystal panel unit 11, the spacer 12, the second liquid crystal panel unit 13, and the light emitting unit 14 are integrated to form the multilayer liquid crystal display device 10.

In addition, when a female screw is not formed in the through holes 111, 121, 131, 141, bolts having a male screw formed at the tip are inserted in the order of the through holes 111, 121, 131, 141 from the front side, and the through holes 141 are inserted. What is necessary is just to fasten a nut to the external thread of the bolt which protruded from.

Further, a concave portion in which the head is accommodated may be provided on the front surface of the support frame 11B so that the head of the bolt does not protrude from the support frame 11B of the first liquid crystal panel unit 11. Moreover, the insertion direction of the bolt may be from the back side. Furthermore, the screw fastening locations are not limited to the four corners, and may be appropriately changed in consideration of strength.

Further, as shown in FIG. 5B, a non-penetrating hole 141 ′ extending from the front surface side to the middle in the thickness direction may be formed in the frame body 14 </ b> A of the light emitting unit 14. Thereby, it can prevent that a volt | bolt protrudes from the back surface of the light emission unit 14. FIG.

With such a configuration, when disassembling the multi-layer liquid crystal display device 10, it is only necessary to remove the bolts, and each part can be easily separated.

In addition, the first single-layer liquid crystal display device 10A can be configured by inserting bolts into the through holes 111 of the first liquid crystal panel unit 11 and the through holes 141 of the light emitting unit 14 and fastening them with screws. However, it is easy to remove the bolt. Similarly, the second single-layer liquid crystal display device 10B can be configured by inserting bolts into the through holes 131 of the first liquid crystal panel unit 13 and the through holes 141 of the light emitting unit 14 and fastening them with screws. Separation is easy because it is only necessary to remove the bolt.

And the convex part 142 is each formed in the front four corners of the frame 14A which the light emission unit 14 has.

The convex part 122 is fitted to the concave part 113 by sliding the spacer 12 in the left-right direction with respect to the first liquid crystal panel part 11. Similarly, the convex part 132 is fitted to the concave part 123 by sliding the second liquid crystal panel part 13 in the horizontal direction with respect to the spacer 12. Similarly, the light emitting unit 14 is slid in the left-right direction with respect to the second liquid crystal panel unit 13, thereby fitting the convex part 142 into the concave part 133. As described above, the first liquid crystal panel unit 11, the spacer 12, the second liquid crystal panel unit 13, and the light emitting unit 14 are integrated to form the multilayer liquid crystal display device 10.
