Definitions
- the present invention relates generally to processor-based devices having multi-layer displays and more specifically the presentation of images displayed on each screen of a multi-layer display device.
- the PureDepth technology incorporates two or more liquid crystal display (“LCD”) screens into one physically combined display unit, where each LCD screen is separately addressable to provide separate or coordinated images between the LCD screens.
- LCD liquid crystal display
- Many of the PureDepth display systems include a high-brightened backlight, a rear image panel, such an active matrix color LCD, a diffuser, a refractor, and a front image plane, which devices are laminated to form a device "stack.”
- a high-brightened backlight such an active matrix color LCD
- a diffuser, a refractor such as a rear image panel
- a front image plane which devices are laminated to form a device "stack.”
- the basic nature of a multi-layer display using stacked screens strongly encourages at least some form of coordination between the various images on the multiple screens.
- the invention relates to multi-layer display devices and provides for the presentation of images to be displayed on each screen or other display of a multi-layer display device using one combined in-plane video image. This allows a single video card, processor, or other logic device to be used with the combined in-plane video image for a multi-layer display device without requiring the images to be synchronized or coordinated due to the use of multiple video cards, processors, or logic devices.
- a method for presenting images in a multi-layer display device having a first display screen and a second display screen may comprise creating a combined single plane image, the single plane image having a first image portion corresponding to images to be displayed on the first display screen and a second image portion corresponding to images to be displayed on the second display screen, transmitting the first image portion to the first display screen, and transmitting the second image portion to the second display screen.

- FIGS. IA and IB illustrate exemplary devices having multi-layer displays.
- FIG. IA shows a generic device 1 having a multi-layer display with two display screens 18a, 18c positioned front-to-back
- FIG. IB shows a wager-based gaming machine 10 having a multi-layer display with three display screens 18a, 18b, 18c positioned front- to-back.
- a predetermined spatial distance "D" separates display screens for the multilayer displays. This predetermined distance, D, represents the distance from the display surface of display screen 18a to the display surface of an adjacent display screen (18b in FIG IB or 18c in FIG IA). This distance D may be adapted as desired by a multi-layer display manufacturer.
- the display screens are positioned adjacent to each other such that only a thickness of the display screens separates the display surfaces.
- the distance D depends on the thickness of the exterior display screen.
- distance "D" is selected to minimize spatial perception of interference patterns between the screens.
- Distance D can be adapted to improve perception of a three-dimensional display. Spatially separating the screens 18a and 18c allows a person to perceive actual depth between visual output on display screen 18a and visual output on rear display screen 18c.
- Layered display devices i.e., multi-layer displays
- display devices or screens 18a, 18b, 18c Under the control of an associated display processor, which may store visual data and/or also facilitate the transmission of display signals, display devices or screens 18a, 18b, 18c generate visual images and information for display to a person or player 3.
- the proximate display devices 18a and 18b each have the capacity to be partially or completely transparent or translucent.
- the relatively flat and thin display devices 18a and 18b are LCDs.
- Other display technologies are also suitable for use.
- Various companies have developed relatively flat display devices that have the capacity to be transparent or translucent.
- One such company is Uni-Pixel Displays, Inc. of Houston Texas, which sells display screens that employ time multiplex optical shutter (“TMOS”) technology.
- TMOS time multiplex optical shutter
- This TMOS display technology includes: (a) selectively controlled pixels that shutter light out of a light guidance substrate by violating the light guidance conditions of the substrate and (b) a system for repeatedly causing such violation in a time multiplex fashion.
- the display screens that embody TMOS technology are inherently transparent and they can be switched to display colors in any pixel area.
- a transparent OLED may also be used.
- An electroluminescent display may also be suitable for use with proximate display devices 18a and 18b.
- Planar Systems Inc. of Beaverton, Oregon and Samsung, of Korea both produce several display devices that are suitable for the uses described herein and that can be translucent or transparent.
- Kent Displays Inc. of Kent, Ohio also produces Cholesteric LCD display devices that operate as a light valve and/or a monochrome LCD panel.
- Other multi-layer display devices are discussed in detail in co-pending U.S. Patent Application No. 11/514,808, entitled “Gaming Machine With Layered Displays," filed September 1, 2006, which is incorporated herein by reference in its entirety and for all purposes.
- each display screen or device 18a, 18b, 18c is generally adapted to present a graphical display thereupon based upon one or more display signals. While each display screen 18a, 18b, 18c is generally able to make its own separate visual presentation to a viewer, two or more of these display screens are positioned (i.e., "stacked") in the multi-layer display such that the various graphical displays on each screen are combined for a single visual presentation to a viewer. [0030]
- the layered display screens 18 may be used in a variety of manners to present visual images to a user or player.
- video data and other visual images displayed on the display devices 18a and 18c are positioned such that the images do not overlap (that is, the images are not superimposed). In other instances, the images do overlap. It should also be appreciated that the images displayed on the display screen can fade-in fade out, pulsate, move between screens, and perform other inter-screen graphics to create additional affects, if desired.
- layered display screens or devices 18 provide 3-D effects. Generic device 1 or gaming machine 10 may use a combination of virtual 3-D graphics on any one of the display screens - in addition to 3-D graphics obtained using the different depths of the layered display devices.
- Virtual 3-D graphics on a single screen typically involve shading, highlighting and perspective techniques that selectively position graphics in an image to create the perception of depth. These virtual 3-D image techniques cause the human eye to perceive depth in an image even though there is no real depth (the images are physically displayed on a single display screen, which is relatively thin). Also, the predetermined distance, D (between display screens for the layered display devices) facilitates the creation of 3- D effects having a real depth between the layered display devices. 3-D presentation of graphic components may then use a combination of: a) virtual 3-D graphics techniques on one or more of the multiple screens; b) the depths between the layered display devices; and c) combinations thereof. The multiple display devices may each display their own graphics and images, or cooperate to provide coordinated visual output.
- Objects and graphics in an overall visual presentation may then appear on any one or multiple of the display devices, where graphics or objects on the proximate screen(s) can block the view of graphics or objects on the distal screen(s), depending on the position of the viewer relative to the screens.
- This provides actual perspective between the graphical objects, which represents a real-life component of 3-D visualization (and not just perspective virtually created on a single screen).
- Other effects and details may be used with respect to such multi-layer displays and their respective devices and systems, and it will be readily appreciated that such other effects and details may also be present with respect to the invention disclosed herein to be used with multi-layer displays, as may be suitable.
- multi-layer displays having two and three display screens have been presented and discussed, it will be readily appreciated that further display screens may be added to the multi-layer display in a similar manner. Such multi-layer displays could potentially have four, five or even more display screens arranged front- to-back in a relatively stacked arrangement, as in the case of the illustrated embodiments having two and three display screens.

- combined in-plane video space 425 may include a third portion (not shown) positioned in a side-by-side orientation adjacent the second portion 435 that may contain video data or other visual images to be displayed on a corresponding third display screen.
- controller 402 A more detailed description of the controller 402 is also provided in co-pending patent application serial number 11/858,849, filed September 20, 2007, entitled “Auto-blanking Screen For Devices Having Multi-Layer Displays", which is hereby incorporated by reference in its entirety for all purposes.
- This combined in-plane video space 425 may assist in the development of the video or other visual image output for front and back multi-layer displays since a single animation may be used. For example, only one timing series or sequence need be created and maintained - rather than two animations that need to be synchronized in time if the two displays were animated using separate video cards, processors, or the like. This also allows games to be developed using this single plane spanning technique where the video or other visual image output of each section in the combined in-plane video space 425 may used to drive a separate display.
- FIG. 5A illustrates a combined in-plane video space having images resembling traditional mechanical reels.
- first portion 430 may transfer images corresponding to front display screen 18a, which includes transparent window portions 15 that permit viewing of the virtual slot reels that are shown on the second portion 435 or back display screen 18c.
- Second portion 430 may transfer images corresponding to back display screen 18c which includes the video reel 125.
- the combined image may be transmitted and displayed on the front display device. Should the image size exceed the resolution or size of the first display device, the remaining images may wrap around to the back display device.
- FIG. 5B illustrates the images from FIG. 5A as would be seen by a user in a multi-layer display device.
- Front display screen 18a outputs video or other visual image data that resembles a silk-screened glass, while the back display screen 18c displays five video reels 125.
- Images on first portion 430 may correspond to images displayed on front screen 18a and images on second portion 435 may correspond to images displayed on back screen 18c.
- Video data or other visual images provided to screen 18a and 18c is configured such that a common line of sight passes through each window portion 15 of front display screen 18a to a video reel 125 of the back display screen 18c.
- Single plane spanning of the images on the first portion 430 and second portion 435 allows a user to simultaneously view the images on the multiple screens of a multi-layer display device without requiring the images to be coordinated or synchronized, such as when the images are provided separately by multiple video cards, processors, or logic devices.
- FIGS. 6 A and 6B illustrate an exemplary pointer when images from the combined in-plane video space are viewed in a horizontal spanning mode, such as in FIGS. 5 A and 5B.
- a difficulty with the software configuration may be that movement of input on the touch screen may no longer match dimensions of the combined in-plane video space.
- movement of a pointer 601 on the touch screen 600 occurs in the resolution of the touch screen, which usually matches the front display screen in a multi-layer display device.
- the term pointer used herein is intended to be any type of indicator on a display screen, such as a cursor.
- the input from the pointer may be received using any input device such as a touch screen, mouse, keyboard, or any other similar device.
- any input device such as a touch screen, mouse, keyboard, or any other similar device.
- the combined in-plane video space includes double the horizontal resolution of the front display 600. This mismatch distorts and ruins the touch screen input since the user's actions are not accurately reflected in the output image.
- a user 602 may want to move pointer 601a in the direction of arrow A to the new location of pointer 601b within first display portion 630.
- First display portion may correspond to images to be displayed on a front display screen of a multi-layer display device.
- the resolution of the touch screen 600 may be 1680x840 and combined in-plane video space may have a resolution of 3360x840.
- the pointer 601a will move at twice its normal speed and the pointer location 600c will end up displayed on second display portion 635 as illustrated in
- Second display portion may correspond to images to be displayed on a back display screen of a multi-layer display device
- the pointer may be calibrated in order to reduce its speed and/or movement.
- the gaming machine stores and uses a calibration routine that translates between the resolution differences of the front display 630 and the combined in-plane video space. In some cases, this may occur without altering the conventional operating system, such as Windows®.
- the calibration software may then functionally reside between the input and the input to the processor 332. More specifically, the calibration software may receive an input from the touch screen display, mouse, or any other input device, alter the input to match the combined in-plane video space resolution, and provide the new altered pointer location to the operating system.
- the pointer 601a may move from its original position to a first distance in a horizontal direction and a second distance in a vertical direction.
- the first distance may be reduced by a ratio of the first display screen resolution and the resolution of the combined in-plane video space 425.
- the first distance may be reduced by a ratio of the touch screen 600 resolution and the combined in-plane video space resolution.
- the pointer 601a will end up at pointer location 600b.
- the pointer In a vertical spanning mode, the pointer may have a similar, but different calibration. In a vertical spanning mode, the second distance or vertical direction may be reduced by a factor of two. In other words, the second distance may be reduced by a ratio of a vertical component of the touch screen 600 resolution and a vertical component of the combined in-plane video space resolution. [0074]
- the example discussed herein illustrates the use of the pointer when images from the combined in-plane video space are displayed on a single screen as illustrate in FIG. 5A. However, it will be appreciated that the same result occurs when the images are presented in a multi-layer display device as illustrated in FIG. 5B.
- the pointer may move from the front display screen 18a to the back display screen 18c.
- the calibration software may limit the pointer movements to the front display, despite differences between the front display resolution and the resolution for the combined in-plane video space.
- the first distance may be reduced by a ratio of the first display screen resolution and the resolution of the combined in-plane video space, which may be 1/3.
- FIG. 7 illustrates a flowchart of an exemplary method for presenting images on each screen of a multi-layer display device. It will be readily appreciated that the method and illustrative flowchart provided herein are merely exemplary, and that the present invention may be practiced in a wide variety of suitable ways. While the provided flowchart may be comprehensive in some respects, it will be readily understood that not every step provided is necessary, that other steps can be included, and that the order of steps might be rearranged as desired. [0077] A single video data or visual image signal may be created for presentation on a multi-layer display device at 700.
- the single video data or visual image signal may be a combined in-plane video space that may allow a single video display device (e.g., using a single video card, processor, and the like) to drive a 3-D display device with multiple layer display panels.
- This combined in-plane video space may assist in the development of the video or other visual image output for front and back multi-layer displays since a single video data or visual image signal may be created rather than many individual visual image signals.
- the pointer in a vertical spanning mode, may be calibrated by reducing the vertical distance of the pointer by a ratio of the vertical component of the first display resolution and a vertical component of the overall combined single plane video space resolution at 712.
- the horizontal and vertical components correspond to the horizontal and vertical component of a resolution.
- a screen having a resolution of 1820x1074 will have a horizontal component of 1820 and a vertical component of 1074. Generally, this prevents the pointer from moving at its normal speed since the screen may be set at a higher resolution.
