Systems, methods, and devices for reducing or eliminating image artifacts due to motion are provided. An electronic display may include an electronic display panel having a display pixel, an optical combiner that directs light from the display pixel toward a viewing area, and display driver circuitry. The display driver circuitry may receive image data that defines a total pulse width for one image frame. The display driver circuitry may cause the display pixel to emit light in multiple pulses totaling to the total pulse width for the display pixel for one image frame.

Pulse splitting for motion artifact reduction

A device may include an electronic display to display image frames. The display may include illuminators that generate light and mirrors that selectively direct the light to pixel locations based bitplanes that set the arrangement of the mirrors. Additionally, the device may include duty cycle balancing circuitry that generates and provides duty cycle balancing signals to the electronic display. In response to the duty cycle balancing signals, the electronic display is implements balancing on bitplanes during at least a first portion of off periods during the image frames and implements balancing off bitplanes during at least a second portion of the off periods such that, in the aggregate, a ratio of respective on times of the mirrors to respective off times of the mirrors is balanced across the image frames during the off periods.

Reflective display mirror hinge memory reduction systems and methods

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

An electronic device may have a display with an array of display pixels. To increase the efficiency of the display, the display may also include an array of microlenses. Each microlens may overlap and focus light from a respective pixel. Pixels for one of the colors of light may have a high aspect ratio. These pixels may be covered by two microlenses or a single cylindrical microlens. The microlens dimensions may be tuned to mitigate non-uniformities in the brightness profiles of the pixels. The microlens edges may be laterally shifted towards or away from the center of the light-emitting areas to either reduce or increase the focusing power of the microlens. The microlenses and color filter elements in each pixel may also be shifted to account for the chief ray angle of the display.

Electronic device displays having microlenses

An electronic display may include an active area having a first pixel formed in the active area, where the first pixel emits light in response to image data. The electronic display may also include a controller to transmit the image data to the first pixel. The first pixel may include an organic light-emitting diode that emits the light in response to the image data, memory to digitally store the image data received from the controller, and driver circuitry to receive the image data from the memory. The driver circuitry may cause the organic light-emitting diode to emit the light in response to the image data.
