Abstract
Disclosed is a solid state wristwatch having an active electro-optical display in the form of light emitting diodes. The display is mounted on one sloping side of a groove in a circular module frame and comprises a ceramic substrate having the display on one side and a large scale integrated circuit on the other. The angular orientation of the display coincides with the axis of an angularly oriented viewing window constructed so that the watch case shades at least part of the display. Viewing under bright daylight is enhanced and through ambient light responsive control of current to the display, battery energy under most viewing conditions is conserved.
