Viewing window for electronic wristwatches employing light emitting diode display

摘要

In electronic wristwatches employing an array of light emitting diodes (LED) as digital display, an ornamental coating is provided over the rear surface of a front glass sheet except the viewing window region thereof through the use of painting, printing, etc., while a color filter corresponding to the color of the light emitting display is provided at least over the viewing window region. With such an arrangement, the visibility is enhanced with a simplified construction.
