摘要： A first electrophoretic medium comprises an electrically charged particle (700) suspended in a suspending fluid, the particle (700) having a polymeric shell having repeating units derived from at least one monomer the homopolymer of which is incompatible with the suspending fluid. A second, similar electrophoretic medium comprises a suspending fluid, and first and second types of electrically charged particle suspended in the suspending fluid, the two types of particle having differing optical characteristics but both having polymeric shells. The polymeric shells are arranged such that homoaggregation of the two types of particles is thermodynamically favored over heteroaggregation.

摘要： Edge effects in electro-optic displays are reduced by (a) ensuring that during rewriting of the display, the last period of non-zero voltage applied all pixels terminates at substantially the same time; and (b) scanning the display at a scan rate of at least 50 Hz.

摘要： A method for addressing a bistable electro-optic display having at least one pixel comprises applying an addressing pulse to drive the pixel to a first optical state; leaving the pixel undriven for a period of time, thereby permitting the pixel to assume a second optical state different from the first optical state; and applying to the pixel a refresh pulse which substantially restores the pixel to the first optical state, the refresh pulse being short relative to the addressing pulse.

摘要： Waveforms for driving electro-optic displays, especially bistable electro-optic displays, are modified by one or more of insertion of at least one balanced pulse pair into a base waveform; excision of at least one balanced pulse pair from the base waveform; and insertion of at least one period of zero voltage into the base waveform. Such modifications permit fine control of gray levels.

摘要： Electrophoretic display units (1) comprising pixels (11) situated between common electrodes (6) and pixel electrodes (5) need, for shortening the total image update times, increased driving voltages across the pixels (11) which endanger transistors (12) coupled to the pixel electrodes (5).These increased driving voltage (V6) to the common electrode (6). To protect the transistors (12) against these increased driving voltages, a setting signal (S1, S2) is supplied to the pixel electrode (5) via the transistor (12) for reducing a voltage across the pixel (11) resulting from a transition in the alternating voltage signal (V6). During driving frame periods (Fd) data pulses (D1, D2, D3, D4, D5, D6) are supplied, and during setting frame periods (Fs), the setting signals (S1, S2) are supplied.

摘要： An electro-optic display comprises first and second substrates and a lamination adhesive layer and a layer of a solid electro-optic material disposed between the first and second substrates, the lamination adhesive layer having a volume resistivity, measured at 10 °C, which does not change by a factor of more than 3 after being held at 25 °C and 45 per cent relative humidity for 1000 hours. The electro-optic material is preferably an encapsulated electrophoretic material. Other desirable characteristics of lamination adhesives for use in electro-optic displays are also described.
