  • Patent number: 9740285
    Abstract: Methods and systems described herein provide for an integrated approach for controlling a user's various devices based on the user's brain activity. A user's brain activity is monitored with a first user device. A change in the brain activity is detected. In response to detecting the change, data from a second user device is processed. The detected change in brain activity is compared to the processed data to determine whether the change in brain activity is associated with the second user device. In response to determining that the change is associated with the second user device, an option is generated for display on a display screen to control the second user device.

  • Patent number: 9721521
    Abstract: The present disclosure discloses a gate driving method, a driving apparatus of a display panel and a display apparatus. The driving apparatus may be in two driving modes, i.e., a first mode and a second mode. In the first mode, due to a reduced number of gate lines to be driven when various frames of images are displayed, the power consumption can be reduced. In addition, due to the effect of persistence of vision of human eyes, better quality of display images can be ensured while reducing power consumption. In the second mode, as respective lines of gate lines are driven progressively when various frames of images are displayed, the display panel is enabled to have better quality of display images. By switching the driving apparatus between the first mode and second mode, a number of gate lines to be driven can be reduced so as to reduce power consumption.
