Abstract
A writing implement is described that dispenses a liquid colorant and produces a magnetic field. The magnetic field may be directed to an electronically driven display having a particle that is responsive to a magnetic field, such as an electrophoretic display, thereby changing an optical state of the display.
Claims20
An apparatus, comprising:
- an elongate tubular member having a first end and a second end and being sized to be hand-held;
- a magnet coupled to the tubular member;
- and
- a tip coupled to the first end of the tubular member, the tip configured to dispense a colorant and to provide a magnetic field.
1 more element
A system for displaying information, comprising:
- an apparatus configured to both dispense a liquid colorant and produce a magnetic field at a desired location;
- and
- an electrophoretic display containing electrophoretic particles configured to change state in response to application of the magnetic field, wherein
- when the electrophoretic display is addressed with the apparatus, a liquid colorant is deposited on a surface of the electrophoretic display and the state of the electrophoretic display behind the colorant changes.
