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 measuring characteristics of an electronic display panel includes an array of optical elements. Each optical element has a first surface and a second surface. The first surface faces the electronic display panel and receives light from pixels of the electronic display panel. The second surface faces away from the electronic display panel and has an area smaller than the area of the first surface. The second surface emits a combined version of the light received by the first surface. The apparatus further includes a light sensor facing the second surface to measure one or more parameters of the emitted light.

摘要： An eyecup assembly includes an electronic display element of a head-mounted display (HMD), a transparent plastic frame, an eyecup of the HMD, and a coupling interface. The plastic frame is laminated to the electronic display element and includes a center portion and a peripheral portion. The center portion includes an optical component and the peripheral portion including at least two protruding alignment structures. The eyecup includes alignment structures coupled to the at least two protruding alignment structures on the frame. The coupling interface interfaces with an alignment system. The alignment system is configured to align the eyecup assembly to the electronic display by adjusting a position of the electronic display relative to the eyecup so that a test image displayed by the electronic display after transmission through the optical component in the frame and an aperture of the eyecup is within a threshold value of a reference image.

摘要： A lens includes an optically transparent substrate having a first lens surface and a second lens surface opposite to the first lens surface. The first lens surface includes a plurality of Fresnel structures. A respective Fresnel structure of the plurality of Fresnel structures includes a slope facet and a draft facet. The draft facet is characterized by a draft angle which is based on a distance of the respective Fresnel structure from a reference axis of the lens. The draft angle is between a first angle and a second angle, the first angle corresponding to a direction of a ray, in a first medium, transmitted from a reference off-axis position through the respective Fresnel structure toward a reference pupil. The second angle corresponding to a direction of the ray, in the optically transparent substrate, transmitted from the reference off-axis position through the respective Fresnel structure toward the reference pupil.

摘要： A method for correcting non-uniformities of one or more display panels of a HMD (e.g., a VR headset or an AR headset) is disclosed, where the method is based on a luminance level of content being displayed. The method includes obtaining the calibration data for correcting non-uniformity of a display panel of the HMD at various brightness levels and storing the data. In response to receiving a request for providing content to be presented on the HMD, the host applies the calibration data based on a luminance level of content being rendered to correct for any non-uniformities of the one or more display panels while rendering the content for display.

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.

摘要： A corner cut liquid crystal display (LCD) device including a LCD panel and a backlight. The LCD panel includes adjacent panel portions of different width that collectively define a corner cut profile shape for the LCD panel. The backlight includes a light guide and light sources that emit light into the light guide. The backlight directs the light from the light sources toward the LCD panel. The light guide includes adjacent light guide portions of different width that define the corner cut profile shape. Each light guide portion illuminates a corresponding LCD panel portion. The LCD device can be incorporated into a head-mounted display (HMD). The corner cut profile shapes of two adjacent LCD devices, one for the left eye and one for the right eye, may define an open region for placement of other components or parts of the user, such as the user's nose when wearing the HMD.

摘要： An electronic display is driven to compensate for non-uniformity in a display property across display regions of the electronic display. Non-uniformity measures are determined for a set of electronic displays. A transformation is determined for converting the non-uniformity measures to transformed non-uniformity representations having fewer dimensions than a total number of the display regions in an electronic display. Using the transformation, a transformed non-uniformity representation for the electronic display is generated and stored, and an inverse transform is determined and stored. A system containing the electronic display generates correction values for the display regions by applying the inverse transformation to the transformed non-uniformity representation. Input display data for the electronic display is modified according to the generated correction values for the display regions. The electronic display is driven according the modified display data.
