摘要： A system calibrates luminance of an electronic display panel. The system includes a luminance detection device, an actuator and a computing device. The luminance detection device comprises a plurality of detectors arranged along a width or length of the electronic display panel to simultaneously measure luminance parameters of at least one row or column of areas in the electronic display panel. Each of the plurality of detectors covers an area in the at least one row or column of the electronic display panel. The actuator is configured to cause a relative translational movement in a length direction or a width direction of the electronic display panel. The computing device is coupled to the luminance detection device to receive the measured luminance parameters, and the computing device is configured to generate calibration data for adjusting brightness of areas of the electronic display panel by processing the measured luminance parameters.

摘要： A liquid crystal display (LCD) device including an LCD panel and a backlight. The backlight includes a plurality of light sources to emit light, and a reflective stack. The reflective stack is positioned to receive light emitted from the light sources and transmit the light to the LCD panel. The reflective stack includes optical elements providing a folded beam path for the light emitted from the light sources to the LCD panel. The light emitted from the light sources is diffused while propagating towards and away from the LCD panel along the folded beam path. The folded beam path has an optical distance that is longer than the spatial distance between the light sources and the LCD panel to improve light diffusion by the backlight without substantially increasing backlight thickness.

摘要： An apparatus for treating pixels or regions of a display panel includes a measuring device configured to measure a parameter of light emitted by one or more pixels of each region of the display panel. The apparatus includes a parameter comparator operably coupled to the measuring device and configured to select one or more pixels or one or more regions of the display panel such that the measured parameter of light emitted by the one or more pixels or the one or more regions exceeds a threshold value. The apparatus also includes a laser device configured to emit a laser beam onto the selected one or more pixels or the selected one or more regions.

摘要： A display device that includes a liquid crystal (LC) panel, a back light unit (BLU), a first data driver, and a second data driver. The back light unit (BLU) emits light during an illumination portion of a frame period and does not emit light during a remaining portion of the frame period. A first data driver writes data to a first portion of the pixels of the LC panel. A second data driver writes data to a second portion of the pixels of the LC panel. The first and second data drivers write data at an overlapping time during a write portion of the frame period. The write portion overlaps in time with the remaining portion of the frame period during which the BLU does not emit 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 virtual reality (VR) includes a sparse projection system configured to generate a plurality of clusters using one or more diffractive optical elements. Each generated cluster has a unique configuration that corresponds to a unique location in a virtual mapping of a local area. The sparse projection system projects the generated clusters throughout the local area. A VR console receives a series of images of the local area from the imaging device, with at least one image includes at least one cluster. The VR console determines a location of a VR headset within the virtual mapping of the local area based at least in part on a configuration of the at least one cluster included in the series of images. Content is generated based at least in part on the determined location of the VR headset and is provided to the VR headset for presentation.

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 liquid crystal display (LCD) device including a circular backlight that illuminates an LCD panel. The backlight is disposed behind the LCD panel and includes a light guide and an array of light emitting diodes (LEDs). The light guide includes a circular top surface, a circular bottom surface, and a connecting surface between the top and bottom surface. The array of LEDs are disposed along the connecting side surface of the light guide in a circular arrangement to emit light into in first directions toward a center of the light guide. The light guide receives the light from the array of LEDs in the first directions and directs the light in a second direction toward the LCD panel from the circular top surface. The backlight can include brightness enhancement films (BEFS), such as first BEF having concentric circular stripe prisms, and a second BEF having radial stripe prisms.

摘要： An electronic display includes a substrate and a thin-film transistor (TFT) layer deposited on a top surface of the substrate. The TFT layer includes a plurality of driving TFTs that are configured to provide current to one or more organic light emitting diodes (OLEDs). The electronic display also includes an emission layer deposited on a top surface of the TFT layer. The emission layer includes emission areas and non-emission areas that separate the emission areas. The emission areas include a plurality of OLEDs and each of the OLEDs are configured to be driven by one or more of the TFTs to emit light. The electronic display also includes a reflective layer formed on a bottom surface of the substrate. The reflective layer is configured to reflect at least some of the light emitted from the OLEDs toward the non-emission areas.
