ABSTRACT:
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.
