An electrowetting display comprises a support plate on which individual electrowetting pixels separated from one another by pixel walls are formed. The individual electrowetting pixels include a first conductive layer and a second conductive layer on the support plate. The first conductive layer and the second conductive layer are separated by a dielectric layer in first portions of the individual electrowetting pixels. The first conductive layer and the second conductive layer are in electrical contact with one another in second portions of the individual electrowetting pixels, wherein the second portions of the individual electrowetting pixels may be U-shaped.

Electrowetting display pixels with patterned electric field

Subject matter disclosed herein relates to arrangements and techniques that provide for harvesting thermal energy within a display, for example an electrowetting display, of an image display apparatus and converting the thermal energy into electricity. The electrowetting display comprises a first substrate and a second substrate opposite to the first substrate, a plurality of pixel portions defined between the first substrate and the second substrate, and a hydrophobic surface on the first substrate. A first fluid is included within the pixel portions and on the hydrophobic surface, while a second fluid is included on the first fluid, wherein the second fluid is substantially immiscible with the first fluid. A pyroelectric layer is included between the first substrate and the second substrate, wherein the pyroelectric layer is configured to absorb thermal energy within the electrowetting display and output a voltage based upon the thermal energy.
