ELECTROWETTING ELEMENT WITH NON-SWITCHABLE COLOR FILTER

摘要

A display apparatus includes an electrowetting element including a non-switchable color filter, a first support plate with a surface having a first part overlapped by the non-switchable color filter and a second part not overlapped by the non-switchable color filter, and a first and second fluid. A control apparatus of the display apparatus is operable to switch the first fluid between at least a first configuration with the first fluid in contact with the first part but not substantially in contact with the second part and a second configuration with the first fluid in contact with the second part and with the first fluid being at least one of: not substantially in contact with the first part or at least partly in contact with the first part.

1. A display apparatus comprising:
an electrowetting element comprising:
a non-switchable color filter configured to absorb at least one wavelength of visible light;a first support plate comprising:
a surface having:
a first part overlapped by the non-switchable color filter, anda second part not overlapped by the non-switchable color filter; andan electrode;a second support plate;a first fluid;a second fluid immiscible with the first fluid, the first fluid and the second fluid located between the first support plate and the second support plate; and a control apparatus comprising:
at least one processor;at least one memory comprising computer program instructions,the at least one memory and the computer program instructions operable to, with the at least one processor, cause the control apparatus to switch the first fluid, by control of application of a voltage between the electrode and the second fluid, between at least:
a first configuration with the first fluid in contact with the first part but not substantially in contact with the second part; anda second configuration with the first fluid in contact with the second part and with the first fluid being at least one of: not substantially in contact with the first part or at least partly in contact with the first part.
