A watch face uses liquid crystal displays along with a reflective polarizer to produce backgrounds with selective appearances. Therein, the watch employs a polarizer to produce polarized light that is passed downward to a liquid crystal display. The liquid crystal display selectively rotates or does not rotate the polarized light. If the light is rotated, a reflective polarizer layer located beneath the liquid crystal display reflects the rotated light back upward off its surface to provide the watch face with a first color. If the light is not rotated, then the light is transmitted through the reflective polarizer layer to a reflective dial surface disposed beneath. The light is then reflected off the dial surface to provide the watch face with a second color. The present invention includes a watch employing a watch face with selectively changing backgrounds which is capable of displaying two or more colors while having a watch face that has reduced overall thickness and can be made to display unique optical effects and patterns.
A watch face with selective backgrounds comprising:
The watch module of claim 20 wherein said module is round and said watch face is octagonal.
The watch face of claim 22 wherein said voltage switching means is electronically actuated.
The watch face of claim 27 where in means for adjusting is electronically actuated.
A watch face with selective backgrounds comprising:
The watch face of claim29 wherein the first background is a silvered mirror.
A watch face with selective backgrounds comprising:
