Substrate are disclosed for use in a light modulator. The substrate may comprise at least one driving electrodes applied to the substrate. The driving electrode is arranged in a pattern across the substrate. The pattern of multiple driving electrodes across the substrate comprises multiple repeated building blocks. Electrodes in the building blocks forming the at least one driving electrode.

Substrate comprising electrodes and light modulator with reduced diffraction

Some embodiments are directed to a light modulator comprising transparent substrates, or a transparent substrate and a reflective or partially reflective substrate, multiple electrodes being applied to the substrates in a pattern across the substrate. A controller may apply an electric potential to the electrodes to obtain an electro-magnetic field between the electrodes providing electrophoretic movement of the particles towards or from an electrode.

Light modulator, light modulator method and smart glazing

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. A controller may apply an electric potential to the electrodes to obtain an electro-magnetic field between the electrodes providing electrophoretic movement of the particles towards or from an electrode.

Light modulator, substrate comprising electrodes and smart glazing

The present disclosure is in the field of an electrophoretic device for switching between a transparent and non-transparent mode, comprising a fluid and particles, electrodes for moving said particles, and comprising various further elements, as well as uses thereof, in particular as a window blind.

Optical modulator

An electrophoretic device for switching between a transparent and non-transparent mode comprises a fluid and particles, electrodes for moving said particles, and various further elements, as well as uses thereof, in particular as a window blind.

A method of manufacturing an electrowetting element. A first fluid is dispensed. A second fluid immiscible with the first fluid is dispensed. A fluid coating around the first fluid and the second fluid is dispensed. The fluid coating is hardened to form a capsule containing the first and the second fluid.

Method for manufacturing an electrowetting device using a hardened fluid coating

Electrowetting element including a compound comprising a plurality of colorant moieties and a linker. The plurality of colorant moieties includes a first colorant moiety having a first net dipole and a second colorant moiety having a second net dipole. The plurality of colorant moieties are linked by and disposed around the linker so that the first net dipole and the second net dipole at least partially cancel each other.

Electrowetting element

A method of dispensing fluids for manufacturing an electrowetting element. The method comprises: dispensing a first layer of a first fluid on a support plate surface; letting a first portion of the first fluid vaporize as a vapor from the first layer into a region over the first layer; removing the vapor from the region over the first layer; and dispensing on the first layer a second layer of a second fluid, the second fluid immiscible with the first fluid.

Fluid dispensing method for electrowetting element manufacture

An apparatus for fabricating one or more electrowetting display devices, wherein the apparatus comprises a fluid dispenser to dispense fluids onto a substrate. The fluid dispenser comprises a first nozzle to dispense a first fluid of the fluids onto the substrate. The fluid dispenser further comprises two or more additional nozzles. Each additional nozzle dispenses a fluid in communication with the first fluid. The fluids dispensed by the additional nozzles combine to form a single second fluid that is substantially immiscible with the first fluid.

Methods and apparatuses for fabricating electrowetting displays

A method comprising: treating a surface to change a surface energy of the surface, in dependence on at least one first parameter value of respectively at least one surface treatment control parameter which provides a surface treatment environment for treating the surface. The method further comprises: applying a first liquid part on a first area of the surface, the first liquid part having a meniscus with an edge contacting the surface; determining a first contact angle; determining, based on the first contact angle, at least one second parameter value of respectively the at least one surface treatment control parameter; and changing the at least one surface treatment control parameter based on the at least one second parameter value.

Method of controlling a surface treatment

An electrowetting element comprises a first fluid and a second fluid substantially immiscible with the first fluid. Greater than or equal to 0.05 wt % and less than or equal to 15 wt % of the second fluid is water.
