  • Patent number: 9818357
    Abstract: A GOA circuit and an LCD are disclosed. The GOA circuit includes multiple cascaded GOA units and a control module. Each of the multiple cascaded GOA units is used for charging a corresponding horizontal scanning line in a display area through driving of a first stage-transferring clock, a second stage-transferring clock, a first control clock and a second control clock. The control module is used to control the gate driving signals to be reset to the first voltage level, that is an ineffective voltage level, after the GOA circuit finishes a charging for all of the horizontal scanning lines simultaneously through the starting pulse signal such that a redundant pulse signal generated on the horizontal scanning lines before the gate driving signal of the first stage GOA unit is outputted is avoided in order to ensure a normal operation of the GOA circuit.

  • Patent number: 9799286
    Abstract: A GOA circuit and LCD are disclosed. The GOA circuit includes cascaded GOA units and a control module. Each of the GOA units is driven by a first level of transfer clock, a second level of transfer clock, a first control clock and a second control clock to charge horizontal signal lines corresponding to a display area. The control module masks the first level of transfer clock and the second level of transfer clock when all of the horizontal signal lines are charged completely by the GOA circuit, such that the gate driving signals on the horizontal signal lines are discharged until the level equals to the predetermined level. In this way, the horizontal signal lines are prevented from generating redundant pulse signals before the first gate driving signals are outputted, which ensures the normal operations of the GOA circuit.

  • Patent number: 9785275
    Abstract: A computing device receives electronic data generated by a touch-sensitive surface in response to a contact made with the touch-sensitive surface, and a tilt sensor detects a tilt angle of the touch-sensitive surface. The tilt angle is indicative of an angular displacement between a reference plane defined by the touch-sensitive surface in a reference position and a current plane defined by the touch-sensitive surface in a current position. A parameter or other aspect of an automated contact discriminating process is modified based at least in part on the detected tilt angle of the touch-sensitive surface. The contact discriminating process determines whether the contact made with the touch-sensitive surface is intentional or not intentional. In response to determining that the contact is intentional, the electronic data is accepted as valid input for further processing. In response to determining that the contact is not intentional, the electronic data is rejected for further processing.
