Abstract: Electronic devices may be provided with displays that have polarizers. A polarizer may be provided with an unpolarized strip. The unpolarized strip may extend across the width of the polarizer and may overlap a light-based component such as a camera that is located in an inactive border area of a display. The polarizer may have a polarizer layer formed form a polymer with a dichroic dye. A strip-shaped opening may be formed in the polarizer layer by cutting out a strip of the polarizer layer with a laser cutting tool or other equipment, a strip of unpolarized material may be formed in the polarizer layer using chemical bleaching, or light-based bleaching techniques may be used to form an unpolarized strip in the polarizer layer.

Abstract: A compensation system includes a processor configured to determine compensated data for display on a sub-pixel of the display device. The processor may receive image data configured to be displayed on the sub-pixel, convert the gray level data to first voltage data; fetch, from a memory, compressed 1×1 sub-pixel uniformity compensation data for the sub-pixel, and decompress the compressed 1×1 sub-pixel uniformity compensation data via a decompressor. The decompressed data comprises the 1×1 sub-pixel uniformity compensation data for the sub-pixel. The processor may also determine a voltage compensation offset value associated with the sub-pixel based on the second voltage data, generate compensated voltage data based in part on the voltage compensation offset value and the first voltage data, convert the compensated voltage data to compensated gray level data; and transmit the compensated gray level data to pixel driving circuitry associated with the sub-pixel.

Abstract: A display may include a display panel that emits light. The light from the display panel may be focused by a lens assembly towards a viewer. A light redirecting layer may be included in the display between the display panel and the lens assembly to ensure that the lens assembly receives incident light at an optimal angle. The light redirecting layer may redirect light by different amounts at different portions of the light redirecting layer. The magnitude of the redirection angle may increase with increasing separation from the center of the light redirecting layer. The light redirecting layer may redirect light away from the center of the light redirecting layer. The light redirecting layer may be a geometric phase lens formed using a liquid crystal film. The display may also include a circular polarizer, an additional circular polarizer, and an additional quarter waveplate.

Abstract: An electronic device such as a head-mounted device may have displays. The display may have regions of lower and higher resolution to reduce data bandwidth and power consumption for the display while preserving satisfactory image quality. Data lines may be shared by lower and higher resolution portions of a display or different portions of a display with different resolutions may be supplied with different numbers of data lines. Data line length may be varied in transition regions between lower resolution and higher resolution portions of a display to reduce visible discontinuities between the lower and higher resolution portions. The lower and higher resolution portions of the display may be dynamically adjusted using dynamically adjustable gate driver circuitry and dynamically adjustable data line driver circuitry.

Abstract: An organic light-emitting diode (OLED) display may have an array of organic light-emitting diode pixels that each have OLED layers interposed between a cathode and an anode. Voltage may be applied to the anode of each pixel to control the magnitude of emitted light. The conductivity of the OLED layers may allow leakage current to pass between neighboring anodes in the display. To reduce leakage current and the accompanying cross-talk in a display, the pixel definition layer may disrupt continuity of the OLED layers. The pixel definition layer may have an undercut to disrupt continuity of some but not all of the OLED layers. The undercut may be defined by three discrete portions of the pixel definition layer. The undercut may result in a void that is interposed between different portions of the OLED layers to break a leakage path formed by the OLED layers.

Abstract: Techniques for implementing and/or operating an electronic device that includes or utilizes a display panel. The display panel includes an organic light-emitting diode layer, an encapsulation layer disposed over the organic light-emitting diode layer, and a color filter layer disposed over the encapsulation layer. The color filter layer overhangs the organic light-emitting diode layer and comprises a first color filter cell of a first color component sub-pixel that at least partially overlaps an organic light-emitting diode of a second color component sub-pixel that is a different color compared to the first color component sub-pixel.

Abstract: An electronic device may have a display that provides image light to a waveguide. First and second liquid crystal lenses may be mounted to opposing surfaces of the waveguide. An coupler may couple the image light out of the waveguide through the first lens. The second lens may convey world light to the first lens. Control circuitry may control the first lens to apply a first optical power to the image light and the world light and may control the second lens to apply a second optical power to the world light that cancels out the first optical power. Each lens may include two layers of liquid crystal molecules having antiparallel pretilt angles. The pretilt angles and rubbing directions of the first lens may be antiparallel to corresponding pretilt angles and rubbing directions of the second lens about the waveguide.
