Description
BACKGROUND

1. Field of the Invention


The present invention relates to a tilt assembly for use with a display screen, and more specifically, towards a tilt assembly for use with a display screen such as a point of sale display in which the tilt assembly may be manipulated to tilt and translate to remove a glare from the display screen.


2. Description of Related Art


Display screens are used as a user interface for many electronic systems. For example, personal computers have traditionally used a display screen to display information relevant to the user of the display screen, and may alternatively be provided with one or more touch-responsive features so that the user can also input information to the electronic system through the display screen.


Occasionally, a glare due to a proximal light or other electronic device may appear to the user as being reflected on the display screen. Display screens are typically placed in a generally upright orientation, and for these display screens in a generally upright orientation, a change in their orientation angle would usually eliminate the glare. This is because the proximal light or electronic device causing the glare was generally from a higher elevation, so the angle of incidence of light reflecting from the display screen was usually large. A slight tilt of the display screen would cause the reflected light, meaning the glare, to be reflected away from the viewer's line of sight.


However, for display screens that are not in a generally upright orientation, tilting of the display screen may not always be effective for eliminating a glare. For example, for point of sale display screens that may be orientated at an angle substantially less than an upright orientation, a tilt of the display screen would not be sufficient to remove the glare because the angle of incidence was usually small for glares produced by an overhead light or the like.


Accordingly, there is a need for a device or system that can eliminate or reduce display screen glare.

In this manner, the display screen 12 is tilted and translated rearwardly with the same input from the user.


As illustrated in each of FIG. 3A, FIG. 3B, and FIG. 3C, a pivot point 50 is defined beneath the base casing 20. The pivot point 50 is defined as such due to the convex cross-section of the base casing 20 about which the base plate 22 translates about. In this manner, the bottom facing surface of the base plate 22 has a correspondingly shaped convex bottom-facing surface to match the upward-facing concave surface of the base casing 20. In accordance with embodiments disclosed herein, the pivot point 50 may be defined below a proximal surface 52 to which the base casing 20 is engaged with. The advantageous placement of the pivot point 50 below the casing 20 allows for minor adjustments to the tilt angle of the display screen 12 by providing a larger radius of movement than if the pivot point was above the surface 52.


The advantageous tilt and translate movement illustrated in FIG. 3A, FIG. 3B, and FIG. 3C is further illustrated in FIG. 4A, FIG. 4B, and FIG. 4C. The cross-sectional view of tilt assembly 14 illustrated in FIG. 4A is representative of the first position as illustrated in FIG. 3A.
