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

The present disclosure relates to systems and methods for operating a control signal to communicate signals using a first antenna and a first frequency band in response to determining that intra-device operations are occurring or are expected to occur, that a first amount of energy received by the first antenna is less than a threshold amount of energy, and that the first antenna is unaffected by the intra-device operations. The control signal may also delay communication of the signals in response to determining that intra-device operations are occurring, and that first amount of energy is greater than or equal to the threshold amount of energy.

Listen-before-talk systems, devices, and methods based on intra-device operations

Local passive matrix displays and methods of operation are described. In an embodiment, the display includes a pixel driver chip coupled with a matrix of rows and columns of LEDs. The pixel driver chips may be arranged in rows across the display with separate portions to operate separate matrices of LEDs.

Local passive matrix display

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.

Hybrid architecture for zero border display

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.

Touch sensing utilizing integrated micro circuitry

Systems and methods may reduce or eliminate image artifacts due to a defective pixel of an electronic display. An electronic display may include pixels that respectively include a self-emissive element, pixel drive circuitry that supplies a pixel drive current to drive the self-emissive element, and signal routing circuitry that reduces or eliminates a visual artifact due to a defective pixel among the pixels. The signal routing circuitry may do this by turning off the self-emissive element, supplying image data from the pixel drive circuitry to a first adjacent pixel, or receiving image data from other pixel drive circuitry from the first adjacent pixel or a second adjacent pixel.

Pixel screening and repair

An electronic display may include a pixel circuit. The pixel circuit may include memory storage to store data values representative of image data to be depicted via the pixel circuit. The memory storage may also include memory components for storing bits of the data value. The pixel circuit may also include a light-emitting device for emitting light based at least in part on the data value and a controller. The controller may receive the data value and store the bits based on a mapping between the bits and the memory components. The mapping may be determined based on routing one or more of the bits associated with one or more defective memory components of the memory components to one or more other memory components of the memory components. The controller may also drive the light-emitting device to emit light based on the bits stored in accordance with the mapping.

Correction for defective memory of a memory-in-pixel display

A system may include a display driven using display driving circuitry to present an image via pixels. The display driving circuitry may include a sensor core compatible with one or more strain sensing circuits. The same sensor core may be used by a control system of the display to sense a stress applied to a strained region of a display using a current divider sensing circuit and/or a Wheatstone bridge sensing circuit.

Display circuitry including strain gauge

A system may include buffer circuitry that receives an input signal representative of image data for display via a pixel. The buffer circuitry may provide a first driving signal during a first frame of the image data to the pixel based on the input signal. The buffer circuitry may include slew booster circuitry. The slew booster circuitry may supply a voltage boost (e.g., additional voltage) to differential pair stage circuitry of the buffer circuit in response to a difference between the input signal and a second driving signal exceeding a threshold increase a rate of change of the input signal provided. The second driving signal may be provided to the pixel during a second frame of the image data preceding the first frame.

Display circuitry including selectively-activated slew booster

A method of adjusting a test gray voltages applied to a component of an electronic display during a test frame between image frames, wherein the adjustment is based at least in part on the control signal to the component during a prior image frame. The method may reduce hysteresis effects on the extraction of sensed currents of the component during the test frame, which may increase the accuracy and/or consistency of determined parameters evaluated from the sensed currents. The determined parameters may include temperature and/or aging of the component. The determined parameters may be used to adjust control signals for the component and other components in a region near the component during the next image frame.
