ABSTRACT:
A liquid crystal indicator label and method for making same includes a liquid crystal material, adapted to change color in response to a change in temperature within a predetermined range, which is adhered to a predetermined surface portion of a transparent substrate and a black background adhered at least behind the liquid crystal material, with an adhesive adhered behind the black background and any portion of the substance not covered by the black background. The liquid crystal is preferably confined to a surface area substantially smaller than the entire surface of the substrate, and a border member is positioned either between the liquid crystal and the substrate or between the liquid crystal and the black background to overlap at least some of the edge portions of the liquid crystal. According to a modified aspect of the invention, the black background covers the entire back surface of the substrate and alpha-numeric characters can be located between the substrate and the black background to display a desired message along with the indicator. As preferable embodied, the label according to the invention is used with a battery charger, with the liquid crystal portion positioned directly adjacent a heat generating circuit element which is adapted to heat up when current flows through battery cells placed in the charger.
