Description
HORIZONTAL THREE SCREEN LCD DISPLAY SYSTEM
Technical Field This invention relates to display systems for computers, and more particularly to a multi-screen display system for use with a computer system, where the multi-screen display system includes three independent liquid crystal display screens disposed adjacently to one another on a common arm extending along a horizontal plane.
Background of the Invention Multi-screen displays are becoming more and more popular for use in various businesses, such as in financial institutions, stock market brokerage firms, engineering companies and the like. These displays are commonly coupled to a single computer and capable of displaying various graphs, charts and other important information simultaneously. Thus, a large amount of data or information can be displayed to the user at any given time, and without the user having to partially cover portions of the information in a "windowed" or layered arrangement, as would be necessary with only a single display screen.
Up until the present, most multi-screen display systems have been limited to two independent display screens positioned side-by-side. The angle of the screens relative to each other has usually not been adjustable, and often the displays have been required to be set directly on a table or desk, thereby using a significant amount of space. To date, there has not been a convenient and efficient means to provide three independent display screens and to support the three screens in a manner which minimizes the footprint area of the system, and which still allows one or more of the screens to be adjusted slightly such that at least two of the screens can be angled or "booked" toward each other to further enhance the ease with which information can be viewed on the three screens.
It is therefore an object of the present invention to provide a display system for use with a computer system, where the display system incorporates three independent display screens supported on a common horizontal support arm, and elevated by a support column so as significantly reduce the footprint area required by the display system.
It is another object of the present invention to provide a display system for use with a computer system, where the display system incorporates three independent CONFIRMATION COPY

liquid crystal display (LCD) screens mounted on a common, horizontally disposed arm.
It is still another object of the present invention to provide a display system for use with a computer system, where the display system incorporates three independent LCD screens, and wherein at least two of the screens are capable of being angled or "booked" toward each other to optimize the viewing angle of the screens relative to the user.
SUMMARY OF THE INVENTION
The above and other objects are provided by a multi-screen display system in accordance with preferred embodiments of the present invention. In one preferred embodiment the display system comprises a base, a support column extending vertically from the base, a horizontally disposed support arm supported on the column, and three independent liquid crystal display (LCD) screens supported on the support arm. In one preferred embodiment each of the LCD screens is coupled to the support arm by a suitable ball joint which allows the viewing angle of each screen to be adjusted to optimize the viewing angle of each screen.
The base is substantially smaller in width than the horizontal support arm, thus freeing up a significant amount of desk space. Since LCD screens are employed, the entire display system is much more compact and able to be placed much closer to a wall or other vertical partition than would be possible with conventional cathode ray tube display systems. The horizontal support column, in one preferred form, is slightly bowed such that the three LCD screens are presented in a slight arc to the user when the user is seated in front of the display system. This further eases the manner in which information can be viewed on the two outer LCD screens.
The display system thus provides a compact yet convenient means for displaying a large amount of information simultaneously on three LCD screens in a manner allowing the user to easily view any one of the screens from a seated or standing position in front of the display system. The display system is sufficiently compact such that it can be used in work areas where three conventional cathode ray tube screens would be too bulky to employ.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to Figure 1, there is shown a three panel liquid crystal display (LCD) display system 10 in accordance with a preferred embodiment of the present invention. The system 10 includes a support system 12 and three independent LCD
screens 14, 16 and 18 which are supported above a work surface 20. The system forms a means for presenting a large amount of information to a user seated or standing in front of the system 10. While not shown, it will be appreciated that each LCD screen 14, 16, and 18 includes its own video controller card which receives information from a computer system (not shown) associated with the display system 10.
Referring to Figures 2-5, the support system 12 can be seen in greater detail with the LCD screens 14, 16 and 18 removed. The support system 12 comprises a base 22, a vertical support column 24 fixedly secured to the base 22, and a slightly bowed or arched horizontal support arm 26. The base 22 includes a pair of feet which provide even further stability in supporting the LCD screens 14, 16 and 18.
Preferably, the base 22 includes a weighted structure, such as a lead plate, which is insert molded with the base to provide a suitably heavy structure for supporting the LCD screens 14, 16 and 18 in a manner that resists tipping of the screens 14, 16 and 18 if same are inadvertently bumped.
The vertical support column 24 is of a suitable height such that when the LCD
screens 14, 16 and 18 are attached to the horizontal support arm 26, the screens are all disposed above the work surface 20. This places the screens 14, 16, and 18 at a convenient viewing height for the user while also freeing up space under the two outer screens 14 and 18 for papers or other items which the user requires access to.
The horizontal support arm 26 is preferably formed (i.e., cast) as a single piece component and has three docking stations 26a, 26b and 26c where a suitable ball joint is attached at each station. One such ball joint 30 is shown in simplified form in Figure 5 attached to docking station 26c. The ball joints 30 allow each LCD
screen 14, 16 and 18 to be precisely angled or "booked" toward the other screens to optimize the viewing angle of each screen relative to the user. The slightly bowed configuration of the horizontal support arm further helps to place the LCD screens 14, 16 and 18 in a manner such that the screens "wrap around" the user and further enhance the ease with which each screen may be viewed. The radius of curvature is preferably within a range of about 24" - 36", and more preferably about 30", which has been found to ergonomically maximize the convenience to the user in viewing the LCD screens.
The horizontal support arm 26 further includes a channel 32, visible in Figures 2, 4 and 5, which forms an area within which power and/or video cables can be positioned to help keep same off of the work surface 20.
Referring now to Figure 6, the horizontal support arm 26 includes a neck portion 34 having a mounting member or portion 36 protruding therefrom and a recess 38. The recess 38 can be seen in greater detail in the drawing of Figure 8.
The mounting member 36 includes an aperture 40 and an aperture 41. The neck portion also 34 includes an aperture 35.
The vertical support column 24 similarly includes a mounting member or portion 42 and a hollowed out area 44. Mounting member 42 includes an aperture 43. A
first boss portion 46 has a threaded bore 48 and a second boss portion 50 has a threaded bore 52. A separate cover 54 is adapted to be secured to the vertical support column 24 by a plurality of external fastening elements (not shown) placed in apertures 56, 5 which extend into bores 58 formed in bosses 60, and into bore 52, within the hollowed out area 44. The cover 54 is shaped to cover the hollowed area 44 and to provide the appearance of an integrally formed portion of the vertical support column 24 when secured thereto.
Referring now to Figure 8, the mounting member 36 of the horizontal support arm 26 can be seen positioned for securing to the vertical support column 24.
The mounting member 42 is inserted within the recess 38, and the mounting member lays over the two boss portions 46 and 50 with apertures 40 and 41 aligned with apertures 48 and 52, respectively. An external fastening element (not shown) can then be inserted through aperture 40 and into bore 48, and a separate external fastening element (not shown) inserted into aperture 35 to engage in aperture 43.
Further external fastening elements (not shown) can be inserted through apertures 56 and into bores 58 and 52 to secure the cover 54 to the vertical support column 24.
The cover 54 is shown positioned on the support column 24 in Figure 9 ready to be secured thereto by external fastening elements.
It will be appreciated that the above-described arrangement permits the horizontal support arm 26 to be removed and an even longer horizontal support arm, possibly long enough to support four LCD screens, could be attached to column 24.
Alternatively, a horizontal support arm adapted to support only two screens could just as easily be secured to the column 24. This construction thus lends itself very well to providing a modularly expandable display system.
It will be appreciated then that the display system 10 of the present invention provides a convenient, user friendly means for supporting three screens along an elevated, common horizontal support arm. This not only frees up workspace on the desk or table on which the display system 10 is disposed, but also presents the display screens at a height above the work surface that makes the display system comfortable to view.
Those skilled in the art can now appreciate from the foregoing description that the broad teachings of the present invention can be implemented in a variety of forms.
Therefore, while this invention has been described in connection with particular examples thereof, the true scope of the invention should not be so limited since other modifications will become apparent to the skilled practitioner upon a study of the drawings, specification and following claims.
It is still another object of the present invention to provide a display system for use with a computer system, where the display system incorporates three independent LCD screens, and wherein at least two of the screens are capable of being angled or "booked" toward each other to optimize the viewing angle of the screens relative to the user.
SUMMARY OF THE INVENTION
The above and other objects are provided by a multi-screen display system in accordance with preferred embodiments of the present invention. In one preferred embodiment the display system comprises a base, a support column extending vertically from the base, a horizontally disposed support arm supported on the column, and three independent liquid crystal display (LCD) screens supported on the support arm. In one preferred embodiment each of the LCD screens is coupled to the support arm by a suitable ball joint which allows the viewing angle of each screen to be adjusted to optimize the viewing angle of each screen.
The base is substantially smaller in width than the horizontal support arm, thus freeing up a significant amount of desk space. Since LCD screens are employed, the entire display system is much more compact and able to be placed much closer to a wall or other vertical partition than would be possible with conventional cathode ray tube display systems. The horizontal support column, in one preferred form, is slightly bowed such that the three LCD screens are presented in a slight arc to the user when the user is seated in front of the display system. This further eases the manner in which information can be viewed on the two outer LCD screens.
The display system thus provides a compact yet convenient means for displaying a large amount of information simultaneously on three LCD screens in a manner allowing the user to easily view any one of the screens from a seated or standing position in front of the display system. The display system is sufficiently compact such that it can be used in work areas where three conventional cathode ray tube screens would be too bulky to employ.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to Figure 1, there is shown a three panel liquid crystal display (LCD) display system 10 in accordance with a preferred embodiment of the present invention. The system 10 includes a support system 12 and three independent LCD
screens 14, 16 and 18 which are supported above a work surface 20. The system forms a means for presenting a large amount of information to a user seated or standing in front of the system 10. While not shown, it will be appreciated that each LCD screen 14, 16, and 18 includes its own video controller card which receives information from a computer system (not shown) associated with the display system 10.
Referring to Figures 2-5, the support system 12 can be seen in greater detail with the LCD screens 14, 16 and 18 removed. The support system 12 comprises a base 22, a vertical support column 24 fixedly secured to the base 22, and a slightly bowed or arched horizontal support arm 26. The base 22 includes a pair of feet which provide even further stability in supporting the LCD screens 14, 16 and 18.
Preferably, the base 22 includes a weighted structure, such as a lead plate, which is insert molded with the base to provide a suitably heavy structure for supporting the LCD screens 14, 16 and 18 in a manner that resists tipping of the screens 14, 16 and 18 if same are inadvertently bumped.
The vertical support column 24 is of a suitable height such that when the LCD
screens 14, 16 and 18 are attached to the horizontal support arm 26, the screens are all disposed above the work surface 20. This places the screens 14, 16, and 18 at a convenient viewing height for the user while also freeing up space under the two outer screens 14 and 18 for papers or other items which the user requires access to.
The horizontal support arm 26 is preferably formed (i.e., cast) as a single piece component and has three docking stations 26a, 26b and 26c where a suitable ball joint is attached at each station. One such ball joint 30 is shown in simplified form in Figure 5 attached to docking station 26c. The ball joints 30 allow each LCD
screen 14, 16 and 18 to be precisely angled or "booked" toward the other screens to optimize the viewing angle of each screen relative to the user. The slightly bowed configuration of the horizontal support arm further helps to place the LCD screens 14, 16 and 18 in a manner such that the screens "wrap around" the user and further enhance the ease with which each screen may be viewed. The radius of curvature is preferably within a range of about 24" - 36", and more preferably about 30", which has been found to ergonomically maximize the convenience to the user in viewing the LCD screens.
The horizontal support arm 26 further includes a channel 32, visible in Figures 2, 4 and 5, which forms an area within which power and/or video cables can be positioned to help keep same off of the work surface 20.
Referring now to Figure 6, the horizontal support arm 26 includes a neck portion 34 having a mounting member or portion 36 protruding therefrom and a recess 38. The recess 38 can be seen in greater detail in the drawing of Figure 8.
The mounting member 36 includes an aperture 40 and an aperture 41. The neck portion also 34 includes an aperture 35.
The vertical support column 24 similarly includes a mounting member or portion 42 and a hollowed out area 44. Mounting member 42 includes an aperture 43. A
first boss portion 46 has a threaded bore 48 and a second boss portion 50 has a threaded bore 52. A separate cover 54 is adapted to be secured to the vertical support column 24 by a plurality of external fastening elements (not shown) placed in apertures 56, 5 which extend into bores 58 formed in bosses 60, and into bore 52, within the hollowed out area 44. The cover 54 is shaped to cover the hollowed area 44 and to provide the appearance of an integrally formed portion of the vertical support column 24 when secured thereto.
Referring now to Figure 8, the mounting member 36 of the horizontal support arm 26 can be seen positioned for securing to the vertical support column 24.
The mounting member 42 is inserted within the recess 38, and the mounting member lays over the two boss portions 46 and 50 with apertures 40 and 41 aligned with apertures 48 and 52, respectively. An external fastening element (not shown) can then be inserted through aperture 40 and into bore 48, and a separate external fastening element (not shown) inserted into aperture 35 to engage in aperture 43.
Further external fastening elements (not shown) can be inserted through apertures 56 and into bores 58 and 52 to secure the cover 54 to the vertical support column 24.
The cover 54 is shown positioned on the support column 24 in Figure 9 ready to be secured thereto by external fastening elements.
It will be appreciated that the above-described arrangement permits the horizontal support arm 26 to be removed and an even longer horizontal support arm, possibly long enough to support four LCD screens, could be attached to column 24.
Alternatively, a horizontal support arm adapted to support only two screens could just as easily be secured to the column 24. This construction thus lends itself very well to providing a modularly expandable display system.
It will be appreciated then that the display system 10 of the present invention provides a convenient, user friendly means for supporting three screens along an elevated, common horizontal support arm. This not only frees up workspace on the desk or table on which the display system 10 is disposed, but also presents the display screens at a height above the work surface that makes the display system comfortable to view.
Those skilled in the art can now appreciate from the foregoing description that the broad teachings of the present invention can be implemented in a variety of forms.
Therefore, while this invention has been described in connection with particular examples thereof, the true scope of the invention should not be so limited since other modifications will become apparent to the skilled practitioner upon a study of the drawings, specification and following claims.
