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： A liquid crystal display (LCD) device including a backlight with an LED assembly. The LED assembly includes a dichroic combiner and two or more different color LEDs. A substrate of the dichroic combiner receives color light from multiple color LEDs at different input regions and propagating in different directions. Dielectric layers within the substrate selectively reflect or transmit the color light to spatially superimpose the color light, and output the color light in a particular direction at a light output region of the substrate. The light output regions of LED assemblies are arranged behind an LCD panel, along one or more edges, to illuminate the LCD panel. The LED assembly provides edge-lighting without requiring LED placement along the one or more edges.

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： A liquid crystal display (LCD) device including a backlight with an LED assembly. The LED assembly includes a flexible light combiner and two or more different color LEDs optically coupled with a first end of the flexible light combiner. The flexible light combiner includes light channels that transmit color light, and output the color light at a second end of the flexible light combiner. The second end defines a light output region of the flexible light combiner. The light output regions of multiple LED assemblies are arranged behind an LCD panel, along one or more edges, to illuminate the LCD panel. The LED assembly provides edge-lit backlighting with enhanced brightness and color gamut, and flexible LED placement within the LCD device.

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. 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.
