A high efficiency, long life, video rate, electrophoretic display comprises fluid containing sub-pixel structures that are periodic, and aligned with a color filter array. A fluid comprising of electrophoretically mobile particles is compartmentalized at the size scale of the individual filters (one per filter) such that the particles may be moved to either allow light to be returned through the same filter back towards the viewer by total internal reflection (TIR) or conventional reflection to create a light state or to be absorbed by the particles to create a dark state. High reflectance is achieved through the use of structures that avoid ITO layers in the light path and reflecting most light, by virtue of a dual control of light by TIR and transmission to a reflector. In one embodiment the structures are in the shape of truncated pyramids.

A light distribution control element includes a first transparent substrate, a second transparent substrate, first control electrodes and second control electrodes provided on the first transparent substrate, light-transmissive regions provided between the first transparent substrate and the second transparent substrate, and electrophoretic elements including electrophoretic particles charged to a specific polarity and having a light blocking property and optically transmissive dispersant. Each electrophoretic element is provided between two light-transmissive regions. At least a part of at least one of the first control electrodes and at least a part of at least one of the second control electrodes both overlap with each of the plurality of electrophoretic elements. Dispersion of the electrophoretic particles changes depending on potential difference between the first control electrodes and the second control electrodes to change a range of outgoing direction of light transmitted through the light distribution control element.

An electrophoretic display (EPD) and a driving method thereof. The electrophoretic display (EPD) includes: an upper substrate and a lower substrate arranged opposite to each other, and an electrophoretic medium disposed between the upper substrate and the lower substrate; the EPD is provided with a plurality of pixels; each pixel includes at least two sub-pixels; colored charged particles of different colors are disposed in different sub-pixels of each pixel; and a first wall electrode and a second wall electrode are respectively disposed on two opposite sides of each sub-pixel.

An electrophoretic element includes a first substrate and a second substrate, an electrophoretic layer that is provided between the first substrate and the second substrate, and a plurality of pixels that are arrayed in a matrix. The electrophoretic element further includes a partition wall that partitions the electrophoretic layer into individual pixels. The first substrate includes, in each of the pixels, at least three electrodes to which mutually different potentials are capable of being applied. The partition wall includes a first part positioned between two pixels that are adjacent along one direction of a row direction and a column direction and a second part positioned between two pixels that are adjacent along the other direction. In a case where one of two pixels that are adjacent via the first part of the partition wall is set as a first pixel and the other is set as a second pixel, the first part of the partition wall at least partially covers each of one electrode of the first pixel and one electrode of the second pixel.

A reflective display device includes a display part including a fluid having dispersed therein particles having charges, an electric field applying unit including an electrode for applying an electric field to the display part, and a controller for controlling a color of light emitted from the display part, by adjusting at least one of an intensity, polarity, application time, number of applications, and application cycle of a voltage applied to the electric field applying unit, wherein the controller resets an alignment state of the particles by applying a driving voltage for controlling the color of light emitted from the display part, and then applying an alternating-current (AC) voltage having a polarity opposite to that of the driving voltage.

Some embodiments are directed to a light modulator comprising transparent or reflective substrates, multiple electrodes being applied to the substrates in a pattern across the substrate.
