The microdriver receives the reordered multiple bit sequences and drives the multiple pixels using the reordered plurality of bit sequences.

Abstract: An integrated touchscreen can include light emitting diodes or organic light emitting diodes (LEDs/OLEDs), display chiplets and touch chiplets disposed in a visible area of the integrated touch screen. For example, the LEDs/OLEDs, display chiplets and touch chiplets can be placed on a substrate by a micro-transfer tool.

In some examples, the touch node electrodes can be formed and coupled to touch chiplets via the display chiplets.

Abstract: Methods and systems for reducing power consumption of a display link by compacting image data to allow the display link to be deactivated for a longer duration. For instance, pixels that correspond to a preset or default value for a display may be omitted from pixel data sent over the display link. Additionally or alternatively, the display link may be divided into multiple lanes that function independently so that a lane of the display link may be deactivated while other lanes are actively transmitting image data.

Abstract: An electronic display includes emission clock routing without the use of repeaters. This may be accomplished by providing row drivers for each emission clock signal on opposing edges of the display panel, so that each set of row drivers may provide the emission clock signal to only a portion of the micro-drivers in each row. The array of micro-drivers may be further segmented (e.g., into four or more sections, an alternating pattern, uneven sections, etc.) to provide similar advantages. Furthermore, rather than using multiplexors to provide the emission clock signals to the row drivers, the emission clock may be hardwired to the row drivers. This may reduce the number of pins and support the provision of more phases.
