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

1 to 3 are views illustrating a three-dimensional multilayer display device according to an embodiment of the present invention.

As shown in FIGS. 1 to 3, the stereoscopic multilayer display apparatus 100 according to an embodiment of the present invention may include an opaque display panel 110 and a transparent display panel 130. In some embodiments, the stereoscopic multilayer display apparatus 100 may further include a diffuser layer 120.

The opaque display panel 110 is a display panel in which an image is displayed only at the front and no image is visible at the rear. The opaque display panel 110 may include pixels arranged in a matrix form to display the main image 111 by an electrical signal.

The main image 111 displayed on the opaque display panel 110 may be a still image or a moving image.

The opaque display panel 110 may be implemented as an organic light emitting diode (OLED) panel or a liquid crystal display (LCD) panel. For example, the opaque display panel 110 may use an LCD panel having a relatively strong characteristic of burn-in phenomenon even when the main image 111 is displayed for a long time.

The transparent display panel 130 is positioned in front of the opaque display panel 110.

The transparent display panel 130 may display the sub image 131.

Since the transparent display panel 130 has transparency, the transparent display panel 130 does not block the output of the rear opaque display panel 110. Therefore, when viewed from the viewer's eye, the main image 111 is displayed on the rear layer and the sub image 131 is displayed on the transparent front layer, thereby displaying a three-dimensional image.

The opaque display panel 110 may display the main image at all times. Here, the main image 111 does not mean a specific image, but refers to an image that is always displayed by the opaque display panel 110, and refers to an image image encompassing an image and a video.

For example, the main image 111 may be an image image which is always displayed to provide a game.

The transparent display panel 130 may display the sub image intermittently. Here, the sub-image 131 also does not mean a specific image, but means an image that is intermittently displayed by the transparent display panel 130, and means an image image that includes an image and a moving image. For example, the sub image 131 may be an image image displayed when a specific event occurs in the game.

The transparent display panel 130 may be implemented as an OLED panel. This is because, unlike the main image 111, the sub image 131 is displayed aperiodically, so that burn-in occurrence is low, and thus, an OLED panel vulnerable to burn-in can be used.

Accordingly, the power consumption of the OLED panel can be reduced because the power consumption is lower than that of the LCD. In addition, since the OLED panel itself is transparent, the transparent display panel 130 may be used as the transparent display panel 130 without having to separately manufacture the transparent display panel 130.

The transparent display panel 130 may include an optical pinhole.

The optical pinhole may be arranged on the transparent display panel 130 to transmit light from the transparent display panel 130, and may increase transmittance according to the formation of the optical pinhole.

Here, the optical pinhole refers to a hole through which only light passes, not a physically penetrated hole.

The optical pinhole may be formed for each pixel of the transparent display panel 130, and the optical pinhole may be implemented as a pinhole formed in a transparent organic light emitting diode (TOLED) panel.

When the transparent display panel 130 is implemented as an LCD panel or a PDP panel, the optical pinhole may reduce the pattern size of the color filter corresponding to each pixel, and may form light to be transmitted to portions other than the reduced pattern. It may be configured.

In one embodiment, the stereoscopic multilayer display device 100 may include a diffuser layer 120.

The diffuser layer 120 is provided between the transparent display panel 130 and the opaque display panel 110. The diffuser layer 120 diffuses while transmitting light. Therefore, when viewed from the front of the three-dimensional multilayer display device 100, it is possible to prevent the moire interference phenomenon caused by mutual interference between the transparent display panel 130 and the opaque display panel 110.

That is, the transparent display panel 130 and the opaque display panel 110 each include a plurality of light emitting elements arranged. The light by the plurality of light emitting elements arranged in the transparent display panel 130 and the light by the plurality of light emitting elements arranged in the opaque display panel 110 interfere with each other, causing a moire interference shape.

Therefore, the diffuser layer 120 is provided between the transparent display panel 130 and the opaque display panel 110, thereby spreading the output of the opaque display panel 110 and outputting the light emitting devices arranged in the opaque display panel 110. By spreading the peak at the wavelength of the light, the interference with the wavelength of the light output from the light emitting devices arranged in the transparent display panel 130 may be prevented, thereby preventing moire interference due to mutual interference.

The diffuser layer 120 may be formed in various ways such as forming a fine pattern to diffuse light in the light transmissive panel, including a diffusing material for diffusing light, or being formed of a semi-transparent material.

For example, when the diffuser layer 120 is implemented as a light transmissive panel, the diffuser layer 120 is disposed at an interval between the opaque display panel 110 and the transparent display panel 130, or the front or transparent display of the opaque display panel 110. It may be installed by bonding to the back of the light-transmitting adhesive.

As a variation of the diffuser layer 120, a diffusion material is mixed with a light-transmissive adhesive, or a semi-transparent material is mixed to be applied to the front of the opaque display panel 110 or the back of the transparent display panel 130, or to diffuse light. It may also be implemented in the form of forming a fine pattern.

In an exemplary embodiment, the opaque display panel 110 may have an antireflection effect of lowering a reflectance of light incident from the transparent display panel 130. Accordingly, the contrast ratio of the opaque display panel 110 can be improved.

Here, the "anti-reflective effect" refers to the effect of lowering the reflectance of light, not only does not mean that there is no reflectance at all, but also collectively referred to that the reflectance is lower than the amount of incident light.

That is, since the opaque display panel 110 itself is opaque, the opaque display panel 110 itself may have a function of an antireflection layer because of the opacity.

4 is a diagram illustrating a three-dimensional multilayer display device according to another embodiment of the present invention.

As shown in FIG. 4, the stereoscopic multilayer display apparatus 100 according to another exemplary embodiment of the present invention may further include a shielding housing 140.

The shielding housing 140 may shield external light from being introduced between the transparent display panel 130 and the opaque display panel 110.

If external light flows in between the transparent display panel 130 and the opaque display panel 110, the main image 111 and the sub image 131 displayed on each display panel are not clear due to the incoming light. It may not appear.

Therefore, the shielding housing 140 seals the circumference of the transparent display panel 130 and the opaque display panel 110 so that external light does not flow between the transparent display panel 130 and the opaque display panel 110. Accordingly, the main image 111 and the sub image 131 displayed on each display panel can be made clear.

For example, the shielding housing 140 may be configured to seal the circumference between the transparent display panel 130 and the opaque display panel 110, and the shielding housing 140 may be the transparent display panel 130 and the opaque display panel. It may be implemented as a case that is installed to secure the 110.

In addition, the shielding housing 140 may be formed of an impermeable material so as not to transmit light, or may apply an impermeable material to the inner or outer surface of the shielding housing 140.

As shown in FIG. 4, the stereoscopic multilayer display apparatus 100 according to another exemplary embodiment of the present invention may further include a visibility controller 160.

When the sub image and the main image are displayed at the same time, the visibility controller 160 may adjust the color attribute of at least one of the sub image or the main image to increase visibility. For example, the visibility controller 160 may adjust color attributes of at least one of the transparent display panel 130 and the opaque display panel 110.

The color attribute controlled by the visibility controller 160 may be any one of hue, brightness, and saturation, or a combination of two or more thereof.

For example, the visibility controller 160 may control to increase the saturation of the sub image 131 so that the sub image 131 displayed on the transparent display panel 130 can be seen clearly and clearly.

As another example, the visibility controller 160 may control to increase the brightness value of the main image 111 displayed on the opaque display panel 110. This is because the diffuser is provided on the front surface of the opaque display panel 110 to control the brightness of the main image 111 in order to reduce the influence of the diffuser.

In some embodiments, the visibility controller 160 may adjust color attributes of both the transparent display panel 130 and the opaque display panel 110.

As shown in FIG. 4, the multilayer display panel according to another exemplary embodiment may further include a front protection panel 150 or a touch panel.

The front protection panel 150 may be positioned in front of the transparent display panel 130 to protect the transparent display panel 130, and the front protection panel 150 may be located at the rear of the transparent display panel 130 and the opaque display. The main image 111 or the sub image 131 displayed on the panel 110 may be light transmissive.

The front protective panel 150 may be bonded to the transparent display panel 130 by a light-transmitting adhesive, and the front protective panel 150 may be formed of glass or synthetic resin.

The touch panel may generate a touch signal, and the touch panel may be a capacitive or pressure sensitive touch panel.

In addition, the touch panel may be positioned in front of the transparent display panel 130 instead of the front protective panel 150 or may be bonded to the transparent display panel 130 by a light-transmissive adhesive, and the touch panel is protected by the touch panel. It may include a panel and a touch sheet.

The protective panel may be formed of transparent glass or synthetic resin, the touch sheet may be bonded to the protective panel, and the touch sheet may be formed with a metal pattern to generate a touch signal.

Here, when the touch panel is positioned in front of the transparent display panel 130, the touch is induced according to the main image 111 or the sub image 131 displayed on the transparent display panel 130 or the opaque display panel 110. It is possible to operate by the touch signal obtained from the touch panel.

As shown in FIG. 5, the game machine 200 having a stereoscopic multilayer display panel according to an exemplary embodiment of the present invention may include the stereoscopic multilayer display panel 100 described above. Therefore, various embodiments of the stereoscopic multilayer display panel 100 described above with reference to FIGS. 1 to 4 may be applied to the game machine 200.

The game machine 200 having the stereoscopic multilayer display apparatus 100 may play a game by displaying a game on the stereoscopic multilayer display apparatus 100, and the main image 111 on the game is displayed on the opaque display panel 110. The transparent display panel 130 may display the sub image 131 on the game.

In this case, the sub image 131 may be an image related to an event displayed when an event occurs in the game.

The game controller 230 may control the game according to the information of the game stored in the memory 235.

In addition, the game controller 230 controls the opaque display panel 110 and the transparent display panel 130 to display the main image 111 of the game on the opaque display panel 110 and the sub image 131 to the transparent display. It may be displayed on the panel 130.

For example, the game controller 230 displays the main main image 111 of the game on the opaque display panel 110 and displays the sub image 131 on the transparent display panel 130 when an event occurs. The image can be provided to the user.

In addition, the game controller 130 may adjust the color property of the transparent display panel 130 or the opaque display panel 110 so that the sub image 131 can be seen more clearly through the visibility controller 160 when an event occurs. have.

In addition, when the anti-reflective layer 115 is formed on the opaque display panel 110 to display the main image 111, the reflection by light may be minimized to provide a clear image having improved contrast ratio.

An optical pinhole is formed in the transparent display panel 130 so that the transparency is high, so that the main image 111 output from the opaque display panel 110 positioned at the rear can be clearly seen.

In addition, the front protection panel 150 may be installed in front of the transparent display panel 130 to minimize damage to the transparent display panel 130 or a touch panel may be installed to perform an operation according to a touch.
