  • Patent number: 11966048
    Abstract: A head-mounted device may have a head-mounted support structure. Gaze tracking systems may be supported by the support structure so that the gaze of a user may be monitored. Lenses may be supported by the support structure. Display systems may provide computer-generated images to the user while the user is viewing real-world objects through the lenses. The gaze tracking systems may include image-sensor-based systems such as glint-based systems. A glint-based gaze tracking system may include light-emitting devices that emit light beams that create eye glints on the surface of a user's eyes and may include an image sensor that measures the eye glints to gather information on the user's gaze. A low-power gaze tracking system may be included in the head-mounted device. The low-power gaze tracking system may use light detectors to measure the magnitudes of respective light reflections of the light beams.

  • Patent number: 11935497
    Abstract: According to an aspect, a display device includes: a first panel including pixels; a second panel including light control pixels; and a light source. When any of the pixels is controlled to transmit light in accordance with an input image signal, blurring processing is applied, a blurring area is formed, and light from the light source transmits through the blurring area and the pixel controlled to transmit light and is emitted from the first panel. When a straight line connecting a user viewpoint and the pixel controlled to transmit light has an angle relative to a normal to the first panel, a center of the blurring area is at a position shifted to a side opposite to a reference normal side relative to the normal to the first panel passing through a center of the pixel. The reference normal is a normal to the first panel passing through the viewpoint.

  • Patent number: 11842678
    Abstract: This document describes techniques and apparatuses for a high-brightness mode on an organic light emitting diode (OLED) display. The techniques and apparatuses set a high-brightness value in a register of a display driver integrated circuit (DDIC) associated with the OLED display of on electronic device. A processor of the electronic device provides a fewer-pulses command to the DDIC, which adjusts a pulse number to control the OLED display at fewer pulses per period. A gamma correction is determined based on the high-brightness value and used to alter content to be presented on the OLED display. As a result, fewer pulses are used in combination with the gamma correction to provide content on the OLED display at a high brightness.

  • Patent number: 11808939
    Abstract: In certain embodiments, pupil-related characteristic detection or spectacles correction/adjustment based thereon may be facilitated. In some embodiments, a stimulus may be presented at a location on a first display of the user device at a first time to cause a first eye of a user to fixate on the location. A stimulus may be presented at the location on a second display of the user device to cause a second eye of the user to fixate on the location at a time subsequent to the first time. Movement of the first or second eye to fixate on the location on the respective first or second display in connection with the stimulus presentation at the second time may be determined. In response to determining that the movement of the first or second eye exceeded a threshold movement amount, a user profile may be generated that includes the user's pupil distance.
