20090231294 | Image display systems - Image display systems are provided, in which a touch sensing circuit includes at least one voltage storing unit to generate a corresponding voltage when a capacitance variation caused by a touch event occurs. The voltage storing unit includes a first capacitor having a first terminal coupled to an alternating current (AC) common voltage from a common electrode and a second terminal coupled to a first node, a first switching element having a first terminal coupled to the second terminal of the first capacitor and a second terminal coupled to the AC common voltage, and a second switching element having a first terminal coupled to the second terminal of the first capacitor. | 09-17-2009 |
20100328280 | IMAGE DISPLAY SYSTEM - An image display system is disclosed. A gate driver drives includes a first side driving circuit and a second side driving circuit. The first and the second side driving circuits are disposed on the both sides of the pixel array. A first shift register receives a first shifted signal to generate a second shifted signal such that the gate driver drives a first row of pixels. A second shift register receives a third shifted signal to generate a fourth shifted signal. A third shift register is coupled to the second shift register and receives the fourth shifted signal to generate a fifth shifted signal such that the gate driver drives a second row of pixels. The first and the third shifted signals are simultaneously generated according to a vertical start pulse, and the second and the fourth shifted signals are simultaneously output. | 12-30-2010 |

20100060610 | SENSING CIRCUIT FOR CAPACITIVE TOUCH PANEL - A sensing circuit for a capacitive touch panel is disclosed. By adding a path for a noise to pass through, the noise is differentially processed through two paths which have the same electrical conditions with each other. The noise is then decreased significantly, and a sensing signal can be detected correctly. | 03-11-2010 |

20100013779 | Systems for displaying images - A system for displaying images includes a touch sensing circuit. The touch sensing circuit comprises a voltage storage unit for detecting whether a touch event has occurred and generates a corresponding voltage. The voltage storage unit comprises first to third capacitors. The first capacitor has a first terminal coupled to a ground terminal and a second terminal coupled to a first node. The second capacitor has a first terminal coupled to the ground terminal and a second terminal coupled to a second node. When the voltage storage unit detects that a touch event has occurred, the second node is coupled to an AC voltage. The third capacitor is formed between the first and second nodes. When the touch event has occurred, a value of the third capacitor is changed, so that the corresponding voltage at the first node is changed. | 01-21-2010 |
