Abstract: An apparatus for aligning coordinate systems of interacting devices includes an interface circuit configured to receive a sensor signal from an accelerometer of a device. The sensor signal represents an impact on the device responsive to tapping of the device and a second device. A second interface circuit is configured to receive a second sensor signal from a second accelerometer of the second device. The second sensor signal represents an impact on the second device responsive to the tapping. A calibration engine is configured to determine a direction of the impact represented by the sensor signal and a direction of the second impact represented by the second sensor signal. The calibration engine is configured to align at least one of a coordinate system of the device or a second coordinate system of the second device based on the direction of the impact and the second impact.

Abstract: A method for detecting a screen tear in a display device for a given frame of video is described. The method includes retrieving an identification code associated with each pixel row of the frame of video and determining whether the retrieved identification code is same across pixel rows of the frame of video. If the identification code is found to be same across the pixel rows of the frame of video, no screen tear is found. On the other hand, a screen tear is detected if the identification code is found not to be same across the pixel rows. An indication of the detected screen tear is provided to the host machine to re-render the frame of video without such screen tear.

Abstract: An electronic display is driven to compensate for aging of pixels in the electronic display. An aging factor is determined based on initial display data for a display portion of the electronic display during one or more monitored frames. The aging factor is indicative of aging of pixels in the display portion of the electronic display due to use corresponding to the initial display data. An aging counter for the display portion is increased based on the determined aging factor. A compensation value is determined for the display portion based on the aging counter for the display portion. Input display data for the display portion is modified during a subsequent frame according the determined compensation value. The display portion is driven with the modified input display data during the subsequent frame.

Abstract: Embodiments of the present disclosure support a head-mounted display (HMD) wirelessly coupled to a console. The HMD includes a positional tracking system, a beam controller and a transceiver. The positional tracking system tracks position of the HMD and generates positional information describing the tracked position of the HMD. The transceiver communicates with a console via a wireless channel, in accordance with communication instructions, the communication instructions causing the transceiver to communicate over one directional beam of a plurality of directional beams. The beam controller determines a change in the positional information. Based on the change to the positional information, the beam controller determines a directional beam of the plurality of directional beams. The beam controller further generates the communication instructions identifying the determined directional beam, and provides the communication instructions to the transceiver.

Abstract: A display device that includes a liquid crystal (LC) panel, a back light unit (BLU), a first data driver, and a second data driver. The back light unit (BLU) emits light during an illumination portion of a frame period and does not emit light during a remaining portion of the frame period. A first data driver writes data to a first portion of the pixels of the LC panel. A second data driver writes data to a second portion of the pixels of the LC panel. The first and second data drivers write data at an overlapping time during a write portion of the frame period. The write portion overlaps in time with the remaining portion of the frame period during which the BLU does not emit light.

Abstract: 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.

Abstract: A method for dynamically illuminating each pixel row of a display device (e.g., an organic light emitting diode display device) for a given video frame is described. For every video frame, the method comprises enabling the driving of a first row of pixels of the display device for a first time period, where the first row of pixels emits light during the first time period. The method also includes enabling the driving of a second row of pixels of the display device for a second time period, where the second row of pixels emits light during the second time period, and the second time period is different (larger or smaller) from the first time period. The first and second time periods may be dynamically adjusted depending on the image to be displayed.
