A display filter having a secure apparatus comprised of spring loaded gripping members for attaching a bezel having a filter medium onto a notebook computer. Gripping members grasp the sides of the notebook computer and the springs exert force sufficient to hold the display filter at a desired location. Further more, the display filter is horizontally adjustable so that the filter medium may be centered over the notebook computer display. When not used on a notebook computer display, the display filter may be stored in a relatively flat form factor by rotating the gripping members such that the protrusions used to grip the side of a notebook computer case may be rotated so that they lay flat against the side of a bezel. In this manner, there are no protruding edges and overall bulk is minimized. Other ways of attachment include the use of L-shaped strip members that are adjustable with respect to the bezel that contain the filter medium. On the extended portion of the L-shaped strip, there is a curved clip-like structure to snap the bezel into place on the notebook computer case and over the notebook computer display. The elongated portion of the L-shaped strip can be adjusted with respect to the bezel holding the filter medium so that when the display filter is attached to the notebook computer case, the filter medium will be centered over the notebook computer display.

Display filter and bezel securement apparatus

The present invention relates to an optical filter including a flexible, transparent substrate coated with a novel combination of optical coatings, and a frame system designed for mounting the optical filter to a television or other visual display screen. A neutral density contrast enhancement is included within the composition of a flexible substrate, or is coated on either the front, the rear, or both of the surfaces of the substrate. A silicone anti-glare hardcoat is applied to both the front and rear surfaces of the substrate. An anti-reflection coating is added to the front surface of the substrate, preferably via sputtering, and designed to reflect a specific color at a preferred brightness measurement. The combination of a front surface anti-reflection coating, front and rear surface anti-glare coatings, and a neutral density contrast enhancement, eliminates the need for an anti-reflection coating on the rear surface of the substrate. A two layer, non-conductive anti-reflection coating, which provides white or close to white reflected color and low reflectance, is preferred. The substrate is substantially flexible which allows the optical filter to be conformed to the major axis of curvature of the television cathode ray tube. The novel frame system permits the filter to be sized to fit many different television sizes or other visual display screens. The novel frame system also permits customized mounting of the optical filter in front of a television or other visual display screen. The frame system preferably includes two rails. The use of only two frame members further results in a pleasant, unobtrusive appearance of the frame system and optical filter.

An adjustable hanger for mounting an article such as an anti-glare filter or electromagnetic shield or other cover on a second article such as a computer monitor. The hanger has an L configuration defined by two legs, a first one of which extends along the side/front of the monitor and the second of which rests on, i.e., is supported on, the top surface of the monitor. In a top mounting embodiment, the first leg of the hanger attaches to the top of the filter. A side mounting version preferably uses two hangers, which attach to opposite sides of the filter. The second or top leg preferably has a high-friction bottom surface or pad for providing non-slip positioning on the monitor. The depending leg includes a clamp or enclosure which mounts on the cover's bezel, providing ease of mounting on and removal from the cover. The relative size and configuration of the clamp and bezel can be selected to provide a secure fit. In one embodiment, the clamp provides an interference fit with the bezel. Alternatively, in combination with the interference fit configuration, a compressible friction pad mounted on the interior surface of the clamp provides slip-free mounting of the clamp along the cover. In other embodiments, mating tabs and holes or mating teeth secure the bezel to the hanger clamp, preferably in combination with an interference fit.

An optical screen or cover for computer monitors and other video displays comprises a frame to which is mounted an optical plate such as an anti-glare screen, and a concave, U-shaped lip which is mounted to the rear of the frame along three sides of the frame. The lip slides onto and off the monitor for mounting and removing the cover. Also, the lip adapts to monitors of different sizes and provides a snug, custom-appearing fit.
