Abstract

A watch has a mirror dial plate assembly comprising a light valve layer, and a light reflective layer. The light valve is controlled by an electronic circuit for its on, off, and variable light transmission. The reflectivity of the mirror assembly is thus controlled. Dial marks are incorporated either on or in the light valve layer, or using a separation transparent layer.

Claims

1. A watch having a mirror dial plate assembly comprising:

dial marks;

an electronically controllable light valve; and

a mirror plate,

wherein the light valve has a visible light transmission less than 5% at the dark state, and a visible light transmission higher than 55% at the clear state.

2. A watch as in claim 1 wherein said mirror plate is integrated into said light valve.

3. A watch as in claim 2 wherein said dial marks are integrated into said light valve.

4. A watch as in claim 1 wherein said light valve has a variable light transmission.

5. A watch as in claim 1 wherein said light valve has ability to display colors at the dark state.

6. A watch as in claim 1 wherein said light valve is addressable in pixels.
