  • Patent number: 9851800
    Abstract: A method, medium, and system are provided for executing computing tasks based on force measurements corresponding to user interactions with a touch screen for a computing device. The touch screen displays content for applications executed by the computing device and receives user interactions. The computing device processes the user interactions to detect force measurements and to associate the force measurements with computing tasks for the applications executed on the computing device. A database stores the force measurements and corresponding computing tasks to identify matches between the stored force measurement for a user and subsequent force measurements received when the touch screen receives additional user interactions. When matching force measurements are located in the database, the corresponding computing tasks are executed by the computing device.

  • Patent number: 9851832
    Abstract: The present invention relates to the field of display, particularly to a display panel, a driving method thereof and a display device. The display panel comprises an array substrate provided with first electrodes and second electrode arranged in a same layer and a color filter substrate provided with third electrodes. The first electrodes and the second electrodes are alternately arranged in parallel at intervals and electrically isolated from each other. The second electrodes and the third electrodes are arranged correspondingly in space. The present invention has the following beneficial effects: by performing rectangular segmentation on the original plate-shaped common electrodes, the display panel ensures that common electrodes during display and driving electrodes during touch are electrically isolated from each other; in addition, as the diving electrodes are connected by redundant data lines, a display device comprising the display panel has a good image display effect and a higher touch sensitivity.

  • Patent number: 9847070
    Abstract: A display may have an array of pixels to display images. Gate line driver circuitry may have stages that supply gate line signals. A gate line may be located in each row of the pixels. Each stage may have an output block that produces a respective one of the gate line signals and may have a carry block that separately produces a carry signal that is provided to a later stage in the gate line driver circuitry. A memory may be provided in at least some of the stages to store signals produced by the output blocks during intraframe pausing operations. At the end of an intraframe pause, the stored signals may be used in restarting production of the gate line signals by output blocks in the gate line driver stages. Circuitry may be used to separately reset the output block and suppress carry signal production by the carry block.
