Multi-mode watch and method for operating the multi-mode watch
First Claim
1. A watch comprising:
- a first display unit;
a second display unit positioned over the first display unit and configured to transmit light, wherein at least one of the first display unit and the second display unit is configured to display a time information image that indicates time;
a first polarizer set positioned between the first display unit and the second display unit; and
a second polarizer set positioned on the second display unit, wherein one of the first polarizer set and the second polarizer set is configured to rotate relative to another of the first polarizer set and the second polarizer set, wherein the second polarizer set comprises a quarter wave retardation member and a linear polarizing member, wherein the quarter wave retardation member is positioned between the second display unit and the linear polarizing member, and wherein the second display unit is positioned between the first polarizer set and the quarter wave retardation member.

Abstract
A watch may include a first display unit, a second display unit, a first polarizer set, and a second polarizer set. The second display unit may be positioned over the first display unit and may transmit light. One of the first display unit and the second display unit may display a time information image that indicates time. The other of the first display unit and the second display unit may display non-time information image, e.g., a user interface element. The first polarizer set may be positioned between the first display unit and the second display unit. The second polarizer set may be positioned on the second display unit. One of the first polarizer set and the second polarizer set may rotate relative to the other for enabling the watch to conceal or show the time information image.

20. A watch comprising:
-
a first display unit; a second display unit positioned over the first display unit and configured to transmit light, wherein at least one of the first display unit and the second display unit is configured to display a time information image that indicates time; a first polarizer set having a first polarization axis and positioned between the first display unit and the second display unit; a second polarizer set having a second polarization axis and positioned on the second display unit, wherein one of the first polarizer set and the second polarizer set is configured to rotate relative to another of the first polarizer set and the second polarizer set; and an electronic device configured to automatically turn on or turn off the second display unit according to a size of an angle between the first polarization axis and the second polarization axis when the first display unit displays the time information image.
