BACKGROUND 
       [0001]    Personal electronic devices that incorporate flat panel displays have become widely available in recent years. Such devices include gaming devices, smart phones and laptop computers. While the clarity and resolution of such displays has steadily increased there has always been an issue with using such devices in unfavorable lighting conditions where the light source causes glare or otherwise reduces the ability of the user to effectively view the information presented on the device&#39;s display. A common example of this is using such a device outdoors in direct sunlight, which can render the device useless as a result of not being able to effectively see what is on the display. 
         [0002]    Current solutions for reducing glare and “wash-out” of the screen images of flat panels include adhesive films that are somewhat effective at reducing glare, but also typically reduce image quality. Such films are also typically a permanent or semi-permanent add on, that is, they are present whether the unfavorable lighting condition exists, or not, thus requiring the user of the device to partially degrade the utility of the device when it is used in favorable lighting conditions in exchange for some improvement when the device is used in unfavorable lighting conditions. Thus there exists a need for a device that will allows users of flat panel devices to effectively shade flat panel displays when the need arises without being required to permanently alter the nature of the display or the device. 
       SUMMARY 
       [0003]    In accordance with the principles of the present invention, a stowable light visor for shading a flat panel display when such a display is used in unfavorable lighting conditions, i.e. conditions that degrade the utility of the displayed information to the user. The stowable light visor includes extendable support members between which a shading material is attached. The device is stowable in a protective cover that provides protection for the flat panel-containing device, or attached directly to the flat-panel device itself. Thus when the flat panel device is used in favorable lighting conditions the stowable visor remains stowed and does not otherwise encumber the use of the flat panel device. The stowable visor, when in the extended or deployed position can be tilted to allow the user to customize the shading effect. 
         [0004]    In one embodiment, a shading visor for a flat panel display in accordance with the resent invention includes a first and a second elongated slideable member, wherein the slideable members are disposed generally opposed to one another. The slideable members integrally mounted to a device and at least a portion thereof slide within at least one channel in the device, thus having a closed position and an open position. There is also a shade portion attached to the first and second slideable members for providing shading of at least a portion of a flat panel display in the open position and that is stowed when the slideable members are in the closed position. 
         [0005]    Yet another embodiment of the present invention is a method of shading a flat panel display including the steps of deploying a slideable shading visor from a closed position to an open position and tilting the shading visor while in the open position to alter the location of the shade portion. 
         [0006]    Yet another embodiment of the present invention is a method of making a shading visor for a flat panel device including the steps of mounting two generally elongated slideable support members to a device, wherein the slideable members capable of attaining an open position and a closed position, and attaching a shade portion to the support members wherein the shade portion is capable of being stowed when the slideable members are within the closed position.

     DETAILED DESCRIPTION 
       [0017]      FIG. 1  shows an embodiment of the stowable visor  10  of the present invention. This embodiment includes generally elongated support members  1  and  2 . This embodiment also includes a shade portion  3 , which is attached to the support members  1  and  2 .  FIG. 2  shows on embodiment of the stowable visor  10  in an extended or open position. 
         [0018]    The support members may be constructed in any fashion such that they allow the shade portion  3  to be moved between an “open” configuration shown, for example, in  FIGS. 3 and 4 , and a “closed” or stowed configuration as exemplified in  FIG. 5 . As such the support members are slideable to move between the open and closed positions. Accordingly support members  1  and  2  may be composed of rigid or semi-rigid material that slides within the channel  5  shown in dotted lines in  FIGS. 3 ,  4  and  5 . The channel may also be on the sides of the device or protective cover as exemplified n  FIGS. 9 and 10 . As an alternative, members  1  and  2  may be telescoping with the outer portion of such a telescope anchored to allow movement within channel  5  and telescoping into the open configuration. Those skilled in the art will appreciate that there are other construction methods that would allow support members  1  and  2  to be moved between the open and closed position, and all such constructions are considered to be within the scope of the present invention. Such methods include allowing the visor to slide up in a plane generally parallel to the plane of the display and rotating out of that plane to provide shade as exemplified in  FIGS. 9 and 10 . 
         [0019]    The stowable visor  10  may be incorporated either directly into the flat panel devise, or as part of an attachable protective cover  4  for the flat panel device, such as shown in  FIGS. 3 ,  4 ,  5 ,  9  and  10 . Such protective covers are presently available for flat panel-containing devices, but no such cover presently incorporates a stowable visor according to the present invention. 
         [0020]    Incorporation of a visor of the present invention into such a protective cover may be accomplished without decreasing the shock protection provided by the protective cover. In fact, the incorporation of a void  5  for the stowage of the visor in the closed position could enhance the shock protection by providing an insulating space between the protected device and impact point with a surface when the device is dropped. 
         [0021]    The incorporation of the visor within a flat-panel device or a protective cover prevents the need to move the visor out of the way when it is not needed in order to use the flat-panel device. As such, the visor is always available for use but poses no impediment to use of the device when the visor is not needed. 
         [0022]    The shade portion  3  of the visor  10  may be constructed of any material that provides a reduction of intensity of undesirable lighting on the flat panel. The shade may be opaque, translucent, perforated or any other composition that will achieve the effect of providing a reduction of undesirable light impingement onto the display. Additionally, the shade portion may be removable in order to allow for replacement if the shade becomes damaged or to allow the user to select different colors and/or properties of the shade material. Alternatively the shade portion and the support members may integrated to form a single unit such that the two elements appear as a unitary structure. 
         [0023]    The shade portion may also contain panels  6  for reducing light impingement from the sides of the display as shown in  FIG. 7 . Such panels or side flaps would fold inward for stowing when the visor is placed in the closed position. Such side panels may be incorporated integrally into the shade  3 , or they may be separately attached to the support members. Such side flaps may also be formed as part of larger folding shade portion as shown in  FIG. 8  which includes a top panel  7 . 
         [0024]    In the open or extended position, the shade  3 , in a coordinated fashion with the exposed portion of supports  1  and  2 , may be tilted as, for example, as shown in  FIG. 6 , to allow the user to customize the shading effect provided by the visor  10 . 
         [0025]    The tilting may be accomplished by constructing the support members of a deformable material. Alternatively the tilting may be accomplished by incorporating hinges in supports  1  and  2 . The hinges in the supports may be infinitely variable or ratcheted. The ratcheted embodiment may be designed to have ratcheted stops throughout the range of motion, or alternatively, with certain selectable angles, e.g., 45 or 90 degrees with respect to the plane of the display. Such hinging may also be accomplished as demonstrated in  FIGS. 9 and 10 . 
         [0026]    Although embodiments of the stowable visor of the present invention have been described in detail, those skilled in the art will also recognize that various substitutions and modifications may be made without departing from the scope and spirit of the invention, as defined solely by the appended claims.
