Abstract: A method for fabricating an electrowetting display may include depositing a first material layer on a support plate; placing a first mask on the first material layer, wherein the first mask covers first portions of the first material layer and does not cover second portions of the first photoresist layer; exposing second portions of the first material layer to electromagnetic radiation; depositing a second material layer on the first mask and the exposed second portions of the first material layer; placing a second mask on the second material layer; and etching to remove portions of the second material layer and the second portions of the first material layer. Portions of the first and second material layers that remain subsequent to the etching form spacers and a grid of pixel wall extensions.

Abstract: A display device includes a first support plate and an opposing second support plate. A pixel region is positioned between the first support plate and the second support plate. A thin film transistor (TFT) structure is formed on the first support plate and associated with the pixel region. The TFT structure includes a source and drain electrode layer. A reflective layer is formed or disposed over the source and drain electrode layer. The reflective layer includes a pixel electrode within the pixel region. A via is between the source and drain electrode layer and the reflective layer to electrically couple the pixel electrode to the source and drain electrode layer. An organic layer is formed or disposed over the via. The organic layer includes an elevated surface over the via.

Abstract: A method for fabricating an electrowetting display may include forming pixel electrodes on a support plate; depositing a first layer on the pixel electrodes; etching portions of the first layer to form pixel walls that partition pixel regions; depositing a second layer on the pixel electrodes and the pixel walls; etching portions of the second layer to form spacers on tops of the pixel walls; and depositing a hydrophobic layer to at least partially cover the pixel electrodes.

Abstract: Instead of using a clear or a semi-transparent notch within an electrowetting display, a colored notch that is the same color of the pixel region extends from one of the pixel walls toward an opposing pixel wall of the pixel region. The colored notches follow a non-flipped arrangement within each of the pixel regions. For example, each colored notch is adjacent to the same respective pixel wall for a pixel region. In other configurations, the colored notches follow a flipped arrangement within each of the pixel regions. For example, a colored notch of one pixel region and a colored notch of another pixel region are adjacent to the same pixel wall (on opposing sides). Instead of including a separate white sub pixel for each pixel, each pixel region is at least partially covered by a white color filter and a color filter that is the color of the pixel.

Abstract: 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 an electrode layer on the support plate, and a dielectric barrier layer on the electrode layer. The dielectric barrier layer comprises a first portion having a first dielectric constant and a second portion having a second dielectric constant that is substantially less than first dielectric constant. A hydrophobic layer is on the first portion and the second portion of the dielectric barrier layer.

Abstract: Subject matter disclosed herein relates to arrangements and techniques that provide for controlling motion of an electrowetting oil within an electrowetting display device. An electrowetting display device comprises a substrate, an electrode on the substrate, a dielectric layer on a first portion of the electrode. The electrode extends along the substrate one of either entirely from a first end of a pixel area to a second end of the pixel area, or from the first end of the pixel area to the second end of the pixel area such that a portion of the substrate is an electrode free portion to thereby define a notch. A first fluid is disposed on a hydrophobic layer and a second fluid is disposed on the first fluid, the second fluid being immiscible with the first fluid. A dielectric constant of the dielectric layer is greater than a dielectric constant of the first fluid.
