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

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.

Display panel redundancy schemes

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

An electronic device may have a display. The display may include an array of pixels formed on a silicon substrate. Display driver circuitry may be formed in a display driver integrated circuit that outputs display data and other control signals for operating the display. An interposer structure may be included in the electronic device. The interposer structure may be attached to the silicon display substrate and may only partially overlap the silicon display substrate. The display driver integrated circuit may be attached to the interposer structure and provide signals to the display pixels through the interposer structure. In another possible arrangement, the display driver integrated circuit may bridge a gap between the silicon display substrate and the flexible printed circuit. The display driver integrated circuit only partially overlaps the silicon display substrate in this arrangement.

Electronic devices with displays and interposer structures

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

Embodiments disclosed herein provide systems and methods for testing and repairing various aspects of an electronic display. The electronic display includes a reference array and an active array. The electronic display also includes test circuitry used to test individual or any combination of pixels of the electronic display. Switches may be disposed between the pixels and the test circuitry to be to repair the various components of the electronic display.

On-chip testing architecture for display system

Methods and apparatuses relating to controlling an emission of a display panel. In one embodiment, a display driver hardware circuit includes row selection logic to select a number of rows in an emission group of a display panel, wherein the number of rows is adjustable from a single row to a full panel of the display panel, column selection logic to select a number of columns in the emission group of the display panel, wherein the number of columns is adjustable from a single column to the full panel of the display panel, and emission logic to select a number of pulses per data frame to be displayed, wherein the number of pulses per data frame is adjustable from one to a plurality and a pulse length is adjustable from a continuous duty cycle to a non-continuous duty cycle.
