Patent number: 10121419Abstract: A head mounted display (HMD) device periodically measures a gamma characteristic of each of a plurality of display panels, then adjusts the characteristic of one of the panels to closely match the other. For example, the HMD device can periodically apply a set of currents to selected pixels at each display panel and measure the resulting sets of voltages at the selected pixels. The set of voltages for each display panel indicates the gamma characteristic of the corresponding panel. The HMD device can apply the sets of voltages to a filter to generate a gamma figure of merit (FOM) for each display panel, and adjust a bias (e.g., a backlight bias or a bias of a light emitting diode (LED)) of one or more of the display panels, so that each display panel exhibits similar gamma characteristics.Type: GrantFiled: November 11, 2016Date of Patent: November 6, 2018Assignee: GOOGLE LLCInventor: Zhibin Zhang

Publication number: 20170295373Abstract: An HMD device encodes different portions of an image for display with different encoding characteristics based on a user's predicted area of focus as indicated by one or more of a pose of the HMD device and a gaze direction of the user's eye(s) identified at the HMD device. By employing different encoding characteristics, the HMD device supports relatively high-quality encoding while maintaining a relatively small size of the encoded image to allow for transfer of the image to a display panel at a high frame rate. Thus, the HMD device can encode a portion of the image that is expected to be in the user's area of focus at a high resolution, and encode the portion of the image that is expected to be in the user's peripheral vision at a lower resolution.Type: ApplicationFiled: December 15, 2016Publication date: October 12, 2017Inventor: Zhibin Zhang
