摘要： A display assembly of a head mounted display (HMD) includes a pancake lens display assembly. The pancake display assembly comprises a first lens with a quarter-waveplate and a partially reflective surface, a second lens with a reflective polarizer, and a display. An alignment system positions the first lens relative to the second lens to align the reflective polarizer of the second lens with the quarter-waveplate of the first lens. The alignment system rotates the first lens about an optical axis to position the quarter-waveplate on the first lens such that the quarter-waveplate and the reflective polarizer on the second lens are at an angle where light transmitted through the second lens and then through the first lens is substantially circularly polarized. The alignment system mounts the second lens to the lens housing such that the quarter-waveplate is at the angle relative to the reflective polarizer.

摘要： An electronic display includes a display panel that operates in a single display mode to provide a single display, or a dual display mode to provide two displays separated by an inactive region. The electronic display includes the display panel and a panel driver. The display panel includes a left pixel region, a right pixel region, and a middle pixel region between the left and right pixel regions. In the single display mode of the electronic display, the panel driver provides first gate signals generated from first input data to the left, right, and middle pixel regions. In a dual display mode, the panel driver provides second gate signals generated from second input data to the left and right pixel regions. The first input data has a first resolution that is larger than a second resolution of the second input data.

摘要： The disclosed system may include (1) a lens assembly that provides an electronically controllable cylindrical power, oriented along an electronically controllable axis, on an optical path between a display device and an eye of a viewer in response to at least one first control signal, and (2) a controller that (a) receives information indicating a cylindrical power component and a cylindrical axis component of an eyeglass prescription for the viewer, and (b) generates, based on the information, the at least one first control signal to cause the lens assembly to provide the cylindrical power component, oriented along the cylindrical axis component, for the viewer. Various other systems and methods are also disclosed.

摘要： An organic light emitting diode (OLED) display including an OLED panel having a series of gore shaped panel portions that form a quasi-spherical display surface. Each gore shaped panel portion includes a middle portion, a first end portion, and a second end portion. The middle portions of adjacent gore shaped panel portions are separated by bend regions. The OLED panel is bent along the first bend regions and each gore shaped panel portion is bent, such as along second bend regions between the middle portion and end portions, to join adjacent first end portions and adjacent second end portions of the gore shaped panel portions. Two OLED displays may be mounted within a head-mounted display (HMD), each behind an optics block. The quasi-spherical display surface of each OLED display generates a substantially flat image for the user after light from the display surface passes through the optic block.

摘要： A head-mounted display (HMD) including an electronic display. The electronic display is configured to output image light. The electronic display includes a display panel including a surface configured to emit image light, and a fiber optic taper. The fiber optic taper includes a mounting surface and a display surface. The mounting surface is formed to, and affixed to, the surface of the display panel to receive the image light from the display panel. The display surface has a shape configured to output the image light corrected for optical distortion in the image light received from the cylindrically curved display panel. The HMD includes an optics block configured to optically direct the corrected image light to an exit pupil of the HMD corresponding to a location of an eye of a user of the HMD.

摘要： A method of providing display uniformity in a display apparatus comprises retrieving first calibration data representing display characteristics of a display panel of the display apparatus, the first calibration data representing luminance responses or color responses of both left and right panel regions of the display panel when corresponding pixels of both the left and right panel regions are supplied same input image data; receiving stereoscopic image data comprising left and right image data to be supplied to the left and right panel regions; and modifying the received stereoscopic image data in accordance with the first calibration data to display a stereoscopic image with a substantially same luminance response or substantially same color response in both the left panel region and right panel region when the first calibration data indicates discrepancy between the luminance response or color responses between corresponding pixels of the left and right panel regions.

摘要： A system for calibrating an organic light emitting diode (OLED) display is presented. The calibration system includes a series of photodiodes coupled to at least a portion of illumination elements of the OLED display, a controller, and a driver circuit. The series of photodiodes is configured to measure, for one or more illumination elements, illumination latencies and time delays associated with different brightness levels. The controller obtains, for each illumination element, information about brightness levels associated with image light emitted from that illumination element for at least two consecutive video frames. Based on the measured latencies, the time delays and the information about brightness levels, the controller determines a driving signal for a driver circuit for each illumination element. The driver circuit applies the determined driving signal to that illumination element to calibrate the OLED display.
