  • Patent number: 10416799
    Abstract: Inadvertent input control techniques are described. In one or more implementations, techniques are described that leverage force to determine a likelihood that a user intended to provide an input, e.g., a selection input (e.g., a “click”), gesture, lift off, and so forth. This is usable to identify taps, hovers, continuation of movement of a drag operation, and so on. Implementations are also discussed that leverage an n-manifold in the product space of contact size and signal strength that is usable to define a likelihood of whether a contact includes an application of force. A variety of other examples are also described, including cursor stability techniques that leverage force in order to control movement of a cursor.

  • Patent number: 10403222
    Abstract: A gate driver on array (GOA) circuit includes a plurality of stages of GOA units cascaded. A first control latch module, a signal processing module, and a second control latch module of an Nth stage GOA unit generate an Nth stage dipulse gate driving signal and an Nth stage cascade signal according to clock signals, and an (N?2)th or (N+2)th stage cascade signal. For the clock signals corresponding to adjacent two stages of the GOA units, a first clock signal is delayed for a predetermined period of time with respect to a second clock signal. The two dipulse gate driving signals generated by the adjacent two stages of the GOA units partially overlap.
