1: Organic Class 9: Display Device

ELP: EL panel (electrol luminescence panel)

The present invention relates to a display device of pachinkogi.

According to the conventional pachinkogi, the shape of the display device (numbers, letters, shapes, etc.) is changed when a person wins a prize, and a specific pattern is formed at the time of stopping. There is a type called a fever type, which is a trademark of Sancheung Corporation. In the display device used for this type, a display panel is provided inside the display device, and the figure is displayed on the screen.

In such a display panel, a low power consumption and a compact structure are particularly preferable. In this regard, the liquid crystal display panel is excellent and widely used as a general display panel.

However, since the liquid crystal display panel itself is non-luminous, the screen is dark and there is a problem in that it is difficult to accurately see the displayed display due to the lack of contrast. Therefore, if applied to the pachinkogi as it is, the displayed pattern lacks clarity, and reduces the expressive power of the pattern.

Therefore, the display device is an important element to increase the interest of the game, so some countermeasures are necessary.

Therefore, as a countermeasure, it is considered preferable to set a backlight light source such as a fluorescent lamp on the rear side of the liquid crystal display panel.

As a specific example, there is a configuration in which a fluorescent lamp is set as a backlight light source and arranged behind the liquid crystal display panel. However, in such a configuration, since the fluorescent lamp itself is a component that requires a space to be installed deep inside, the entire display device becomes a considerable thickness. For this reason, handling as a display apparatus alone becomes inconvenient, and when it is installed in a pachinkogi, the amount of protrusion to the rear becomes large and there is a possibility that it will hit during transportation.

In addition, since the fluorescent lamp is a linear light source, it is difficult to arrange it so that the entire surface of the liquid crystal display panel is uniformly irradiated, resulting in uneven luminance.

In addition, since the color of the light emitted by the fluorescent lamp is not clearly displayed, it cannot be said to be sufficient to make the displayed pattern colorful in color, and it is difficult to be satisfied to increase the interest of the game.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object thereof is to provide a display device which is compact in design and rich in design power.

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a display device mounted on an organic panel of a pachinko group. It is set as the structure by which the electric luminescence panel (henceforth an EL panel) for backlit combined use is provided.

According to the above configuration, the display on the EL panel is transmitted through the liquid crystal display panel, and the display on the liquid crystal display panel is increased in contrast due to the back irradiation light from the EL panel serving as the surface light emitting source.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

First, a pachinkogi equipped with a display device will be described with reference to FIG.

Various granular spheres are arranged on the organic panel 1, of which (2) to (5) are ordinary granular spheres, while (6) to (8) show variations in the pattern of the display device 9 described later. It is starter to start. In addition, as a result of winning any one of the start ports 6 to 8, a pattern that is variably displayed on the display device 9 (a three-digit number variably displayed by the EL panel ELP described later) is displayed. When a specific knitting can be obtained when a certain time has elapsed and the vehicle is stopped, the winning prize state 10 is set so that the charging entrance port 10 disposed below the display device 9 is opened for a predetermined time.

The display device 9 disposed substantially in the center of the organic panel 1 has a case body 12 as shown in FIG. 1, and the display device 9 has a housing 14 of the case body 12. Is inserted into the mounting hole 13 opened in the organic panel 1, and the whole apparatus is comprised. The housing 14 is formed in a tubular shape that is open in both front and rear directions, and forms an angle, and a transparent cover plate 15 is fitted in the front open part.

Moreover, inside the housing 14, the liquid crystal display panel LCP and EL panel ELP which are mentioned later are arrange | positioned so that it may not shift | deviate on substantially the same line back and forth. Both panels are mounted together on the mounting substrate 16 to constitute a display unit as a whole. The mounting substrate 16 is sandwiched between the cover member 17 covering the rear of the housing 14 and the housing 14, and is firmly tightened and fixed by screws or the like.

Also (11)-(11) are pinwheels.

As shown in FIG. 2, the liquid crystal display panel LCP of the present embodiment forms a liquid crystal cell by sandwiching the liquid crystal 18 into the transparent substrates 19 and 20 at both front and rear sides, and on both sides thereof. It has a structure of TN diodes to which polarizing plates 21 and 22 are attached. In addition, the liquid crystal display panel LCP is capable of obtaining sufficient transmitted light even when no voltage is applied to the liquid crystal. In this state, the display on the EL panel ELP described later is transmitted through the liquid crystal display panel LCP. can do.

Although not shown in detail, the transparent electrodes are arranged in a matrix shape on the inner surfaces of the transparent substrates 19 and 20, and the substrate is connected to the conductive connector 23 as shown in FIG. It is connected with the printed wiring on the mounting board 16 in between. The mounting substrate 16 is connected to a control device 28 (refer to FIG. 5, which will be described later) constituted by a microcomputer, whereby the liquid crystal display panel LCP is separated from the control device 28. According to the instruction, a predetermined character or an appropriate pattern shape can be variably displayed according to the dot matrix method.

In the specific display style of the liquid crystal display panel LCP in this embodiment, the display itself is always in a non-display state, and transmits and displays three-digit numbers variably displayed on the EL panel ELP described later. When the "winning state" as described above is reached, a message such as "Congratulations on winning!", For example, is displayed on the LCD panel side in the horizontal direction.

On the other hand, for the specific structure of the EL panel ELP, as shown in FIG. 3, the insulating film 25 is laminated on the back surface of the phosphor 24, and the transparent electrodes (segment electrodes) 26, 27 are formed on both sides thereof. It is attached to. That is, in the EL panel ELP, three-digit numbers can be displayed in the horizontal direction according to the seven-segment method. Moreover, these electrodes 26 and 27 are connected with the printed wiring on the mounting board 16, and are further connected to the said control apparatus 28, and are controlled for lighting.

In the present embodiment, however, a three-digit numeric part is always left, and a positive display is made in which other parts (background) other than this are lit as one segment. The display state, that is, the setting in which the switching of the lighting state is made so as to be in the front lighting state in which all the segments are lit. EL light emission (in this embodiment, a monochromatic light emission of yellow-orange color is used, but only the numeric segments can be set to change the light emission color) except for the portion of the three-digit number display. Digital display can always be enjoyed by vivid colors, and when it is a winning state, this serves as a backlight for the display on the liquid crystal display panel (ELP).

As shown in FIG. 5, the controller 28 mainly includes a CPU 29 for performing digital arithmetic processing, a ROM 30 for storing programs and fixed data, a RAM 31 for storing arithmetic processing results, and the like. It consists of microcomputers which are made into parts. Then, according to the program stored in the ROM 30, a signal from the granularity detection switch 33 with the waveform shaping circuit 32 inserted is input to the CPU 29 as input information, and the EL, Lighting control of both display panels or operation control of the solenoid 34 for opening / closing the stand mouth 10 are performed.

The display device of this embodiment is configured as described above. Therefore, the display (positive display) on the EL panel ELP is always transmitted through the liquid crystal panel ECP in the display device 9. If there is a prize opening to the start ports 6 to 8, the display on the EL panel ELP starts to change in accordance with a command from the control device 28. As a result, if a combination of "winning state" is obtained when the display is stopped, the whole surface of the EL panel ELP is turned on, and the above-mentioned message is displayed on the liquid crystal display panel LCP while undergoing a back irradiation thereon. .

The results of the present embodiment are enumerated. In the display device, the numbers on the EL panel ELP can be displayed with a bright emission color (yellow orange color in the present embodiment) as the background, so that the display becomes dynamic and increases the interest of the organizer. In addition, since the display of the "winning state" is performed by the liquid crystal display panel (LCP) by the dot matrix display, it is easy to set various displays, such as various patterns or combinations with these, in addition to the message of the present embodiment. Do. In addition, when these displays are performed, the backlight is irradiated by the EL panel ELP. Thus, as described above, an appropriate contrast can be obtained together with the vivid color display, and the display is very easy to see.

In addition, two types of panels having different pattern-expressing powers such as EL panel and liquid crystal display panel were set, and one of them was segment display and the other was matrix display. The range of setting can be expanded, and the effect of enjoying a variety of displays can be enjoyed even by the owner.

Further, the liquid crystal display panel LCP may be segmented. In this case, the expressive power is slightly inferior to that of the matrix display, but there is an advantage that the display control is simplified. In addition, the EL panel ELP may be displayed by a dot matrix method. In this case, display control becomes complicated, but the expressive power is increased.

In addition, by using the EL panel, the display and the backlight function can be used together, so that the number of parts is small, easy construction, and the overall display device can be thinned. In addition, uneven luminance can be reduced by using a surface illuminant called an EL panel. In the case of the present embodiment, since the EL panel ELP is almost the same size as the liquid crystal display panel LCP, the uniformity of luminance is easy.

Moreover, since both panels are united by being bonded onto the mounting substrate 16, they are convenient for handling or pasting. In addition, the EL panel ELP does not easily explode as in the case of fluorescent lamps, and has an advantage of not requiring much attention during knitting.

Further, by interposing a light diffusion plate between the EL panel ELP and the liquid crystal display panel LCP, the EL panel ELP can be miniaturized.

Further, in the present embodiment, the liquid crystal display panel LCP is always set to no display, but an appropriate pattern display may be performed in an area that does not interfere with the transmissive display area of the EL panel ELP. In contrast to the present embodiment, the EL panel ELP may be in the form of a negative display, but a positive display is preferable for a display that is viewed continuously for a long time.

In addition, when displaying the "winning state", for example, the EL panel ELP may alternately display the positive display and the negative display alternately, so that the display may be flickered to add more dynamic to the display.

In addition, the EL panel ELP may be used instead of the conventional seven-segment LED without using the liquid crystal display panel LCP.

The effects of the present invention are as follows.

Since the EL panel is used for transmissive display, dynamic color is added to the display according to the vivid color emission, and the display on the liquid crystal panel also receives this vivid backlight illumination, so that a clear and colorful display can be obtained. Can be increased even more. In addition, by using two kinds of displays such as an EL panel and a liquid crystal display panel, the display can be switched or organized to display a variety of patterns.

Furthermore, since the EL panel is used as both a display and a backlight, the structure of the display device is simplified, and at the same time, the overall thickness of the device can be reduced. As a result, the display device can be easily handled, and the amount of rear projection when installed in the pachinkogi can be reduced, and damage can be prevented.

In addition, since the EL panel is a surface light emitting source, it is possible to contribute to the realization of uniform brightness.
