摘要： A display includes pixels distributed in a pixel array of rows and columns that are grouped in mutually exclusive pixel clusters on a display substrate in a display area. Cluster controllers are disposed on the display substrate and are each connected to the pixels in a pixel cluster to control the pixels to emit light. A display controller external to the display area is connected to each row of pixels in each pixel cluster with a row wire. Each row of pixels in each pixel cluster can be connected with a cluster row wire and the corresponding cluster row wires of each pixel cluster can be connected together. The cluster controllers can be disposed between pixels in the pixel cluster or between adjacent pixel clusters on the display substrate.

摘要： The disclosure describes various aspects of backplanes, including unit cells, architectures, and operations. In an aspect, a backplane unit cell is described that includes first and second switches, a storage element, a comparator, a source (e.g., a current or voltage source), where the source generates a drive signal to control light emission of a selected one of the light emitting elements in a display, and where the drive signal is based on a power signal selected by the second switch. In another aspect, a device is described that includes a backplane configured in an active matrix topology including multiple data columns and multiple row selects; and a set of electrical contacts associated with the active matrix topology and configured to electrically couple the backplane with the display, the display having multiple light emitting elements configured in a passive matrix topology. Methods of operation of the backplane are also described.

摘要： There are provided display controllers and driving methods related to those described in US Published Patent Application No. 2013/0194250. These include (a) a display controller having an update buffer, means for removing from the update buffer pixels not requiring updating, and means to ensure that pixels having certain special states are not removed from the update buffer; (b) a method of driving a bistable display wherein, in a pixel undergoing a white-to-white transition and lying adjacent another pixel undergoing a visible transition, there is applied to the pixel one or more balanced pulse pairs and at least one top-off pulse; (c) a method of driving a bistable display by overlaying a non-rectangular item over a pre-existing image content and then removing the item, where only pixels in the region of the item perform transitions (including self-transitions); and (d) a method of driving a bistable display in which a proportion of background pixels not undergoing an optical change are subjected to a refresh pulse to correct optical state drift.

摘要： A current-selectable light-emitting-diode (LED) display includes pixels distributed in an array of rows and columns. The pixels are grouped in mutually exclusive clusters and cluster controllers are connected to each pixel in a cluster of pixels to control the pixels in the cluster to emit light. Each cluster controller comprises a selectable current source. Each of the selectable current sources can include cluster current sources that are responsive to a current-select signal to enable one or more of the cluster current sources. The pixels can include micro-LEDs and the cluster controller can be disposed between the micro-LEDs. The display can be disposed on a display substrate with signal wires. The signal wires can include separate wire segments that are electrically connected through regeneration circuits that regenerate the signals. The display can be an information display or a backlight.

摘要： Systems and apparatuses for hybrid micro-driver architectures having time multiplexing for driving displays are described. In one embodiment, a display (e.g., hybrid display architecture) includes a backplane and a micro-driver circuitry that is coupled to the backplane. The backplane includes circuitry (e.g., sample and hold circuitry) for sampling and holding analog data and for time multiplexing analog data. The micro-driver circuitry includes at least a capacitor of a ramp generator for generating a ramp voltage based on the analog data of the backplane and drive circuitry to cause at least one emission pulse for emitting a display element.
