Claims20
A flash imaging device comprising:
- (a) an optical change component that reversibly changes an optical property in response to an applied thermal stimulus, wherein said optical change component is chromic or luminescent;
- (b) a pliable, solid substrate;
- and
- (c) a thermal stimulus element configured to apply a thermal stimulus in a sufficiently controlled manner to said optical change component of said device to produce a defined display, wherein said stimulus element comprises a conductive medium.
