摘要： A lens includes immobilized liquid crystals. The liquid crystals in a first region are aligned in a first orientation. The liquid crystals in a second region, located between the first region and a third region and adjacent to the first region and the third region, are aligned in a second orientation that is distinct from the first orientation. The liquid crystals in the third region, located between the second region and a fourth region and adjacent to the second region and the fourth region, are aligned in the first orientation. The liquid crystals in the fourth region, located adjacent to the third region, are aligned in the second orientation. A device with the lens and an array of light emitting devices is also disclosed.

摘要： A head mounted display system includes a display device and an eyetracking device. The display device includes a liquid crystal (LC) panel comprising a plurality of rows of pixels, a back light unit (BLU), and a data driver. The BLU emits light during an illumination period of a frame period from an illumination start time and does not emit light for a remaining portion of the frame period. The eyetracking device determines an eye gaze area of a user in a pixel area of the display device. The illumination start time varies based on a location of the eye gaze area of the user. Liquid crystal material in a row of pixels of the LC panel outside the eye gaze area of the user transitions during the illumination period.

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： 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.

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 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： A method includes sequentially transmitting, through a beam steering device, light of a first color and light of a second color that is distinct from the first color. The method also includes applying a first voltage to the beam steering device for transmission of the light of the first color through the beam steering device; and applying a second voltage to the beam steering device for transmission of the light of the second color through the beam steering device. A device configured to perform the method is also described.

摘要： Disclosed is a liquid crystal display device comprising a liquid crystal layer including a plurality of liquid crystals in a pixel area and a backlight unit coupled to the liquid crystal layer. A plurality of pixels are disposed in the pixel area. The backlight unit is configured to project light towards the entire pixel area of the liquid crystal layer during an illumination time period of a frame time, and not to project the light towards any of the pixel area of the liquid crystal layer during a non-illumination time period of the frame time. By enabling the backlight unit for the illumination time period less than the frame time, image streaking and latency can be reduced.

摘要： A light intensity modulator array includes a first substrate with a two-dimensional array of electrodes; a second substrate with one or more electrodes; and liquid crystal located between the first substrate and the second substrate. The two-dimensional array of electrodes is arranged in a first direction and a second direction that is not parallel to the first direction. A respective electrode of the two-dimensional array of electrodes is distinct and separate from a first adjacent electrode and a second adjacent electrode of the two-dimensional array of electrodes. The first adjacent electrode is adjacent to the respective electrode in the first direction and the second adjacent electrode is adjacent to the respective electrode in the second direction. A method for tracking an eye using a device including the light intensity modulator array is also disclosed.
