20140198022 | DRIVING MODULE WITH COMMON CONTROL NODE - A driving module with a common control node according to the present invention is revealed. The driving module comprises a plurality of output units, a forward input unit and a reverse input unit. The output units are all coupled to a control node to share the control node. The output units output forward scanning signals sequentially according to the charge of the control node when the control node is charged by the forward input unit. The output units output reverse scanning signals sequentially according to the charge of the control node when the control node is charged by the reverse input unit. Thus, the present invention is provided to output forward or reverse scanning signals from the output units by sharing the control node so as to decrease the circuit area in the driving module. | 07-17-2014 |
20140159505 | TOUCH CONTROL SYSTEM AND SENSING METHOD THEREOF - A touch control system and a sensing method thereof. Wherein, a plurality of sensor units are connected respectively to a control electrode line and a detection electrode line. Each sensor unit includes: a first switching element and a second switching element connected in parallel, and a sensing electrode connected to the second switching element. A common electrode provides a trigger signal to each sensing electrode to form coupling. The control electrode line is used to selectively output a turn-off signal in sequence to each of the first switching elements, so that the detection electrode line acts in cooperation with the sensor unit, in response to the turn-off signal. When a touch action occurs, the sensing electrode utilizes the detection electrode line to detect variations of current signal passing through the sensor unit, based on turn-on extent of the second switching element, hereby obtaining at least a touch message. | 06-12-2014 |
20140092036 | TOUCH PANEL WITH SINGLE ELECTRODE LAYER - The invention provides a touch panel with a single electrode layer, which has a plurality of sensing channels. Each of the sensing channels includes a plurality of first transmission lines, a second transmission line and a plurality of first and second sensing electrodes on a substrate. The routing path of the first and second transmission lines routed on the substrate is non-straight. And, the first sensing electrodes and the second sensing electrodes include a plurality of first holes and second holes, respectively. The second sensing electrodes and the first sensing electrodes are disposed on the same side of the substrate. The geometric shapes of the first holes and the second holes correspond to the geometric shapes of the routing path of the first transmission lines and the second transmission line routed on the substrate. Thereby, the display quality can be improved by the touch panel of the present invention. | 04-03-2014 |
20140062979 | BIDIRECTIONAL SCANNING DRIVING CIRCUIT - The invention provides a bidirectional scanning driving circuit, which comprises N stages of driving modules. Driving module comprises an output unit, a forward input unit, and a reverse input unit. For the n-th stage driving module, the forward input unit receives a first input voltage and a front forward scan signal of any of the driving modules lower than or equal to (n−2)th stage for charging or discharging a control node of the output unit. The reverse input unit receives a second input voltage and a back reverse scan signal of any of the driving modules higher than or equal to (n+2)th stage for charging or discharging the control node of the output unit. When the forward input unit is charging the output unit, the output unit outputs a forward scan signal; when the reverse input unit is charging the output unit, the output unit outputs a reverse scan signal. | 03-06-2014 |
20130328800 | IN-CELL TOUCH DISPLAY DEVICE - An in-cell touch display device comprises a plurality of pixel structures, a display scanning circuit, a touch scanning circuit, and a control module. The pixel structures are applied to display an image and include a plurality of display scanning lines and a plurality of common electrodes. The display scanning circuit is coupled with the display scanning lines for actuating the pixel structures to display the image. The touch scanning circuit is coupled with the common electrodes so as to receive a touch signal by scanning the common electrodes. The control module is coupled with the display scanning circuit and the touch scanning circuit to receive and process the touch signal for executing the touch step. The display scanning circuit and the touch scanning circuit are integrated on the same substrate to reduce the thickness of the touch display device without affecting the touch effect. | 12-12-2013 |
