An electronic device may include an electronic display including display pixels to display an image based on compensated image data. As image data is written to a pixel in the row of pixels, capacitive coupling at a driver may lead to distortion on the driver. In particular, the capacitive coupling may cause distortion at a storage capacitor, which may lead to current droop at the pixel. The current droop may be reduced or eliminated in each pixel by performing pixel compensation. The pattern of the pixel compensation may be selected such that, over a number of subframes, an average amount of light is the same or similar to what would be emitted had pixel compensation been performed on each pixel in each subframe.

In-pixel compensation for current droop and in-pixel compensation timing

A display system may include a plurality of light emitting diodes to emit light, where each of the light emitting diodes are connected in parallel and a plurality of first switches respectively coupled to the plurality of light emitting diodes. A first switch of the plurality of first switches is coupled in parallel to a first light emitting diode. The first switch may short the first light emitting diode of the plurality of light emitting diodes through a defined resistor having a defined value that therefore draws a defined short circuit current.

Systems and methods for mitigating micro-LED failures

Electronic devices, displays, and methods are provided for performing row shuffling to reduce an appearance of image artifacts during eye movements such as saccades. An electronic display may include a number of rows of display pixels and driving circuitry to drive the rows of pixels. The driving circuitry may spatially shuffle or temporally shuffle, or both spatially and temporally shuffle, a row order of driving the rows of display pixels.

Emission row shuffling for pulsed electronic displays

Electronic devices, displays, and methods are provided for operating an electronic display in coexistence with sensors that could be adversely impacted by the operation of the electronic display. An electronic device may include an electronic display and a sensor. The electronic display may display image content by light emission during an emission period and periodically enter a quiet period in which the light emission of the electronic display is turned off. The sensor may perform sensing operations during the quiet period without interference from the operation of the electronic display.

Display panel redundancy schemes and methods of operation are described. In an embodiment, and display panel includes an array of drivers (e.g. microdrivers), each of which including multiple portions to independently receive control and pixel bits. In an embodiment, each driver portion is to control a group of redundant emission elements.

In accordance with embodiments of the present disclosure, a device may include a pulsed emission electronic display having multiple display pixels in order to display an image frame. The display may pulse one or more display pixels of over a plurality of sub-frames within the image frame based on display image data. The device may also include image processing circuitry to generate the display image data based on source image data indicative of an image to be displayed during the image frame. Additionally, the image processing circuitry may dither an order of the plurality of sub-frames.

Hybrid architectures and method methods of operating a display panel are described. In an embodiment, row driver and pixel driver functions are combined in a group of backbone hybrid pixel driver chips, wherein global signal lines are distributed to the backbone hybrid pixel driver chips, where the global signals are manipulated and distributed to a row of pixel driver chips.

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. The integrated touchscreen can also include electrodes disposed in the visible area of the integrated touch screen. The electrodes can be capable of providing display functionality via the one or more display chiplets during display operation (e.g., operating as cathode terminals of the LEDs during the display operation) and capable of providing touch functionality via the touch chiplets during touch operation (e.g., touch node electrodes can be formed from groups of the electrodes and sensed). In some examples, the touch node electrodes can be formed and coupled to touch chiplets via the display chiplets.
