    • 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.
    • 表面使用液晶显示器以及反射型偏振器来产生具有选择性外观的背景。 其中,手表使用偏振器产生向下通向液晶显示器的偏振光。 液晶显示器选择性地旋转或不旋转偏振光。 如果光被旋转,则位于液晶显示器下面的反射偏振器层将旋转的光反射回其表面的上方,以向表表面提供第一种颜色。 如果光不旋转,则光通过反射偏振器层透射到设置在下方的反射表盘表面。 然后光从表盘表面反射出来,为表面提供第二种颜色。 本发明包括一种手表,其使用具有选择性变化的背景的表面,其能够显示两种或更多种颜色,同时具有减小总厚度的表面并且可以显示独特的光学效果和图案。
