Abstract:
1. A light emitting device, comprising: an excitation plate; a first set of electrodes connected to the excitation plate, at least one electrode of the first set of electrodes is biased to a first voltage at a first point in time, the first set of electrodes is arranged in a first direction; a second set of electrodes connected to the cover plate, at least one electrode of the second set of electrodes is biased to a second voltage at the first point in time, the second set of electrodes is arranged in a second direction, the second direction is perpendicular to the first direction; a cover plate; and quantum dots, the quantum dots suspended within a liquid between the excitation plate and the cover plate, the quantum dots emit light in response to an evanescent field, the evanescent field is generated by one or more electromagnetic waves undergoing total internal reflection within the excitation plate, the quantum dots are attracted to the at least one electrode of the first set of electrodes at the first point in time.
