Abstract: Subject matter disclosed herein relates to driving schemes that provide for improved data writing to pixels of electrowetting display devices. Subframes are defined within an input frame for providing data to pixels of an electrowetting display. Blocks of rows of pixels are also defined. The blocks are defined based upon driving schemes for the electrowetting display. In an embodiment, the driving schemes include a block driving scheme and an interlaced driving scheme. With a block driving scheme, the rows of pixels are grouped sequentially into blocks, i.e. block 1 includes rows 1-4, block 2 includes rows 5-8, etc. With an interlaced driving scheme, every Nth row is included in a block such that block 1 includes rows 1, 5, . . . , block 2 includes rows 2, 6, . . . , etc. Individual blocks are written to during the subframes thereby allowing for all rows to be handled during the input frame.

Abstract: The subject matter disclosed herein relates to conversion of RGB image data into RGBW image data for display by an image display apparatus. The image display apparatus accesses Red Green Blue (RGB) image data that corresponds to one or more images to be displayed by a Red Green Blue White (RGBW) display of the image display apparatus. The image display apparatus receives one or more inputs. Based upon the one or more external factors, the RGB image data is converted into RGBW image data. Based upon the RGBW image data, the RGBW display displays the one or more images.

Abstract: An electrowetting display device may comprise pixels that include: a hydrophobic layer portion disposed on a first electrode, electrowetting fluids overlying the hydrophobic layer portion, and a thin film transistor (TFT) that is in electrical contact with the first electrode. The electrowetting display device also comprises a display control circuit in electrical contact with a drain or a source of the TFT of each of the pixels to provide a drive voltage to the drain or the source of the TFT of each of the pixels, and a reset control circuit in electrical contact with the drain or the source of the TFT of each of the pixels to provide a reset voltage pulse to the drain or the source of the TFT of each of the pixels. A magnitude of the reset voltage pulse may be based, at least in part, on the drive voltage.

Abstract: A method of driving an electrowetting display device for displaying images. The display device has a plurality of display elements arranged in an active matrix. The matrix has rows and columns. A specific display element is addressed by applying a voltage to the display elements along the column of the specific display element and selecting the row of the specific display element. The method includes determining a first group of rows where the voltages to be applied to the display elements in a predefined column or group of columns are within a first range smaller than a range over which the voltage is controllable; and selecting the rows in the first group consecutively.

Abstract: In a system having a matrix of electrowetting display elements, a column driving system transmits a column voltage signal to an electrode of each electrowetting display element of at least one selected row of n rows of electrowetting display elements. A first row driving system transmits a first row voltage signal to a switchable element associated with each respective electrowetting display element of the selected row. A second row driving system transmits a second row voltage signal to the switchable element associated with each respective electrowetting display element of rows of the n rows of electrowetting display elements. A configuration of respective first and second fluids of the electrowetting display elements of at least one row of the n rows is controlled by selectively transmitting: the first row voltage signal using the first row driving system, and the second row voltage signal, using the second row driving system.
