Abstract: Embodiments of the present disclosure relate to a display assembly with dynamic brightness compensation. The display assembly includes a display element, a controller, and a backlight device. The controller obtains gaze information for a user's eye, generates emission instructions based at least in part on the gaze information, and dynamically assigns at least a portion of a plurality of light sources in the backlight device to a plurality of regions based at least in part on the gaze information. The light sources emit light through the display element, and the display element spatially modulates the light received from the backlight device to generate image light. Each subset of the light sources dynamically assigned to a respective region emits a portion of the light having brightness adjusted by a respective adjustment value in accordance with the emission instructions.

Abstract: Ghost image formation due to reflections of image light by a display panel to an ocular lens may be suppressed by ensuring that the image light reflected by the lens does not get reflected by the display panel back towards the lens. To that end, the display panel may include a quarter-wave birefringent layer between the top polarizer of the display panel and a layer inside the display panel that the image light reflects from, such as a black grid layer or an active matrix layer.

Abstract: A display device improves the grounding connection of a polarizer by using a metal bridge that couples the polarizer to a ground of the display device. The display device includes a backlight unit (BLU) for providing light for displaying an image, a plurality of pixels for modulating the light provided by the BLU, a polarizer for filtering the light provided by the BLU, and the metal bridge. The metal bridge is disposed in a non-display area surrounding a display area of the display device.

Abstract: A display panel has an array of pixels backlighted by a backlight including a lightguide and a plurality of out-coupling gratings. The locations of the out-coupling gratings are coordinated with positions of pixels in the array of pixels. The backlight may include a light-conducting transparent slab or an array of linear waveguides running parallel to the rows of the pixel array, with the gratings formed in the slab or in the waveguide. Wavelength composition and polarization of the light emitted by the waveguide may be matched to the transmission spectral bands and transmission polarization of the display panel.
