Description:
BACKGROUND 
       [0001]    Conventional manners of tinting glass include the use of a film that is applied to a sheet of glass, for example a car window. Tinting a glass surface can be desirable for a variety of reasons, such as reducing the amount of sunlight that enters an area behind the glass, for example to keep a car or building cooler. The tint may also be used to enhance security, for example by preventing people outside of the tinted area from seeing or viewing the contents or activities within the tinted area. Additionally, tint can be used to improve the aesthetics or attractiveness of an item onto which tint is applied, for example making a car have a desired appearance. 
         [0002]    Tinting can be performed in several manners. One example is treated or colored glass. In the case of automobiles or other applications, such glass is typically factory manufactured at a higher cost than regular, untinted glass. Another manner of tinting glass is the use of tinting film. The film is coupled to the glass with an adhesive and is smoothed to provide a uniform appearance. The tint level for these manners of tinting, however, is static and new treated glass or a new tint needs to be applied if a change in the desired level of tint is desired. 
         [0003]    Additionally, the tinting can suffer from a variety of drawbacks after its application. Bubbles in the tint can faun as a result of improper application of tinting film. This can be aesthetically displeasing as well as negatively affect the desired purpose of the tint. Tinting film can also degrade over time, decreasing its effectiveness. Further, treated or tinted glass can be expensive to manufacture or procure. Additionally, if a level of tint applied becomes undesirable, changing the level of tint requires removal or replacement. 
       SUMMARY

In addition, for each of the embodiments described herein, the corresponding form of any such embodiments may be described herein as, for example, “a computer configured to” perform the described action. 
         [0014]    Referring generally to  FIGS. 1-4 , embodiments disclosed herein describe methods, systems and apparatuses for providing tint. In exemplary embodiments, a powered display or displays, such as a flexible liquid crystal display or known variations thereof, may be coupled with one or more glass surfaces, such as a window. The display or displays may be substantially transparent in an unpowered state. Further, a controller coupled with the display or displays may be capable of varying the level of transparency, or tint, of the display or displays. 
         [0015]    Referring now to exemplary  FIG. 1 , a tinting apparatus may be shown. Tinting apparatus  100  may include a window  102  and a display  104 . The window  102  may be any type of window, for example an automobile window, a window on a building or any other type of window. Although many of the exemplary embodiments described herein may relate to one or more automobile windows, it may be appreciated that the methods, systems and apparatuses described herein could be applied to any window or other surface where tinting or a change in the visual characteristics of the window or other surface may be desired. The window  102  may be formed and shaped in any known manner, as desired. Additionally, window  102  may be mounted or actuated in any desired manner, for example mounted on or with a door and door frame of an automobile and actuated in an electrical manner, mechanical manner or any combination thereof. 
         [0016]    Still referring to exemplary  FIG. 1 , window  102  may have a display  104  coupled thereto. Display  104  may be coupled to all of window  102  or any desired portion thereof. Display  104  may be coupled with window  102  in any desired fashion, including, but not limited to, adhesives, mechanical couplings and the like. Display  104  may be mounted on an interior portion of a window or an exterior portion of a window, as desired. Display  104  may be a substantially durable and flexible display that may be shaped into any desired form. Such displays commonly include, but are not limited flexible liquid crystal displays (LCDs), flexible organic light-emitting diode displays (OLEDs), active-matrix organic light-emitting diode displays (AMOLEDs) and the like. Such displays are known to be substantially flexible, so as to allow for mounting to a curved surface. Additionally, many of these displays are thin and highly resilient to damage, for example scratches or impact damage. Further, such displays may be powered or charged and then retain an image thereon even after the power or charge is removed from the display. This may be beneficial for use when, for example, an automobile is turned off and parked. Additionally, the displays can provide for any type of image or coloring as desired, including, but not limited to black or shades of black, static color images, dynamic or moving color images, or any other desired color or image. For example any desired colors or combination of colors may be used, image data may be displayed, advertisement data, logo data may be displayed or any other desired information or data may be displayed on any desire portion of display  104 . This could include, for example, the display of a company logo on a desired portion of the display  104 . Additionally displayed information may be displayed outwardly, for example in the form of an advertisement that is viewable outside of a vehicle or building on which display  104  is utilized. Additionally, display  104  may be such that its displayed tint or data may be such that it complies with any local rules or regulations, for example a state law on a percentage of allowable tint that may be utilized on an automobile window. 
         [0017]    In still further exemplary embodiments, display  104  may be wholly or substantially transparent. Such displays may be further examples of the LCD, OLED, and AMOLED displays discussed above. Further, display  104  may be powered in any known manner. For example, display  104  may include module, harness or connector  106 . Module  106  may provide incoming power to drive display  104 . Additionally, as shown in more detail below, module  106  may be coupled with a central control unit and a power source. In some exemplary embodiments, module  106  may be coupled to display  104  using an adhesive or magnetic coupling. Additionally module  106  may receive or transmit data or power in a wired or wireless fashion to and from a central control unit and to and from display  104 . 
         [0018]    In a further exemplary embodiment, display  104  may be formed in any of a variety of shapes and sizes. For example, display  104  may be shaped to fit windows having certain dimensions so as to substantially cover the entirety of an interior or exterior portion of the window. Additionally, display  104  may be shaped so as to couple with an automobile window on a specific make and model of an automobile. Additionally, groupings of displays may be formed and packaged together so as to substantially fit any number of windows on a specific make and model of automobile. 
         [0019]    Referring now to exemplary  FIG. 2 , windows with associated displays on an automobile  200  may be shown. In this example three windows with displays coupled thereto,  202 ,  204  and  206 , may be shown. Such windows may now be able to provide varying levels or tint or an alternative display thereon. In one exemplary embodiment window and display  202  may be substantially transparent or have a very low level of darkness or tint. This may be a result of display (such as display  104  described above) either not being powered or being powered in such a fashion that the display remains substantially transparent. Window and display  204 , however, shows the display on the window where there is a level of power provided that substantially and effectively provides a tint, darkness or shading to the window. This may be a desired setting that a user or operator has chosen to reduce glare, reduce inward visibility or enhance security. In still another exemplary embodiment shown in  FIG. 2 , window and display  206  may be powered such that the window appears substantially darker or opaque. Additionally, as may be appreciated, display in any of these exemplary embodiments may be powered at any desired level to provide any desired level of tint or transparency, for example ranging from substantially transparent to substantially opaque. 
         [0020]    Referring now to exemplary  FIG. 3 , a configuration  300  of an automobile equipped with a number of displays that are associated with windows may be shown. In this exemplary embodiment the displays ( 306 ,  308 ,  310 ,  312  and  314 ) may be coupled to or mounted on windows, as described with previous exemplary embodiments. A power source  302  may connected with each of displays  306 - 312  as well as to controller  304 . The power source may further be coupled with a wiring harness or module associated with each display. These modules can include module  316  on display  306 , module  318  on display  308 , module  320  on display  310 , module  322  on display  312  and module  324  on display  314 . Modules  316  through  324  may be used to provide power or data, in a wired or wireless fashion, to displays  306  through  314 , regulate power or perform any other desired function associated with driving the displays. Power source  302  may be any desired form of power source, for example a 12V power source, or any other power source associated with an automobile that may be capable of powering any primary or auxiliary items associated with the automobile. In some other exemplary embodiments, the power source  302  may be a solar power source coupled with or otherwise connected to an automobile. Power source  302  may further be such that it can be regulated to provide a desired amount of power or voltage to any of displays  306  through  314 . 
         [0021]    Still referring to exemplary  FIG. 3 , controller  304  may act as a central control unit for the configuration  300 . Controller  304  can include a voltage adjuster or regulator that can be used to activate, deactivate or adjust displays  306  through  314 . In one exemplary embodiment, the adjuster or regulator may be a knob that allows for a substantially broad range of variations to be made to displays  306  through  314 , for example adjusting the tint or darkness of the displays. In another exemplary embodiment, controller  304  may include any number of buttons that may be used to activate, deactivate or adjust displays  306  through  314 . For example a first button may be pressed to power or tint display  306 , a second button may be pressed to power display  308  and so forth. Similarly, any number of different knobs or other controls may be utilized to control any of displays  306  through  314  individually or collectively. Further, other known types of control or adjustment devices or mechanisms, such as, but not limited to, touch screen displays, may be utilized with or as controller  304 . In still other exemplary embodiments, controller  304  may be integrated with any other control functions found in an automobile. Similarly, in exemplary embodiments where a number of displays are associated with windows or doors on a house or building, a central control unit may be utilized to control an individual display, all displays or any number of displays, as desired. In such examples, the controller may be a stand-alone unit or may be integrated with another device, such as a computer-controlled thermostat, home computer or the like. 
         [0022]    In operation, the displays  306  through  312  may be operated or adjusted as desired. Similar to the previous exemplary embodiments, each display may be operated so as to darken any desired amount. This may allow for the windows to have a tinted effect and may result in any of the benefits of tinting. Further, as desired, one or more of the displays  306  through  314  may be darkened or tinted to any desired level independently of any other display. For example it may be desired to have displays  306  and  308  have a lower level of tint or darkness whereas displays  310 ,  312  and/or  314  have a greater degree of darkness or tint. However, it may be appreciated that any desired adjustments may be made to any desired display or displays  306  through  314  at any time. Further, it should be appreciated that any number of displays may be associated with controller  304 , for example a building having a large number of windows with displays associated therewith. 
         [0023]    In a further exemplary embodiment, and referring now to  FIG. 4 , a method of utilizing displays with windows or glass may be described. In step  402  the size and types of windows may be evaluated and the appropriate displays may then be obtained. For applications such as automobiles, a wide variety of templates associated with installation kits may be available. For example a kit containing display templates that are sized properly to the windows of a specific year, make and model of an automobile may be obtained. Such a kit could contain the appropriately sized displays, a mounting or coupling mechanism (such as adhesive) used to couple the displays to a window, display modules for the displays, a controller and any desired wiring or hardware that can be utilized to install the displays and put them into an operable state. 
         [0024]    In step  404  the windows or glass onto which the displays are to be mounted or coupled may be removed from their fitting and location. In the embodiments regarding automobiles, the windows may be removed from a door or door frame. In embodiments related to housing or buildings, the glass may be removed from a window frame. Then, in step  406 , the window or glass may be cleaned and prepared, as desired. This can include the removal of any dirt or cleaning of the window, the elimination of any abrasions or imperfections in the window or any other manner of smoothing or preparing the window. Such a step may be desired in order to provide for a more consistent application or coupling of a display to the glass of a window. 
         [0025]    In step  408 , a display may be affixed to the window. As described previously, this can include the use of a known adhesive to couple the display to a window or any other desired manner of mounting, affixing or coupling the display to the window. As the display may have been formed to the shape of the window onto which it is being coupled, any cutting or otherwise shaping the display may not be necessary. However, it can be appreciated that kits may be provided that allow a user to cut or shape a display in any manner desired. Additionally, the coupling or mounting of the display may be such that it is applied smoothly to the window, for example without any air bubbles or other imperfections that may prevent the display on the window from being substantially transparent when mounted in an unpowered state. Further, in step  408 , a module associated with the display, for example a wiring harness, may be included on the display template to be mounted or may otherwise be coupled to the display at that time. 
         [0026]    In step  410 , a window onto which a display has been mounted may then be reinstalled into its original or desired location. As the display mounted on a window may be substantially thin, for example a few millimeters, the reinstallation of the window into an original location may not require any refitting or changing of the original location. However, a user could refit the window in any desired manner. 
         [0027]    In step  412 , the display may be wired and connected to a central controller and power source. A kit with template displays may be such that it is substantially plug and play. For example, after a window with a display is mounted in an automobile, the display module may be connected, for example using wires, to a controller, such as controller  304  described in exemplary  FIG. 3 . The controller  304 , which may also be included in a kit, may then be connected to a power source, such as power source  302  described in exemplary  FIG. 3 . Upon completion of these connections, the system may be substantially active and may allow for a user to operate the displays in any of the exemplary manners described above. 
         [0028]    The foregoing description and accompanying figures illustrate the principles, preferred embodiments and modes of operation of the invention. However, the invention should not be construed as being limited to the particular embodiments discussed above. Additional variations of the embodiments discussed above will be appreciated by those skilled in the art. 
         [0029]    Therefore, the above-described embodiments should be regarded as illustrative rather than restrictive. Accordingly, it should be appreciated that variations to those embodiments can be made by those skilled in the art without departing from the scope of the invention as defined by the following claims.
