    Abstract: 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.

    Abstract: 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.

  • Publication number: 20140062979
    Abstract: 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.

  • Publication number: 20130328800
    Abstract: 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.

  • Patent number: 6956550
    Abstract: A drive module of liquid crystal panel is formed by arranging a plurality of transversal signal scan lines and a plurality of longitudinal data transmission lines on a liquid crystal panel. A signal scan control IC and a data transmission control IC having a memory component and a panel controller built therein are disposed at the upper and lower sides of the liquid crystal panel, respectively. Each of the data transmission lines is connected to the data transmission control IC with the shortest distance. The signal scan lines are connected to contacts at two sides of the signal scan control IC from two sides of the liquid crystal panel. The earlier a signal scan line is for scan, the closer to the inner side it is connected to a contact on the signal scan control IC.

  • Patent number: 6867833
    Abstract: The present invention discloses a transflective mode color liquid crystal display, whose white backlight source is composed of several narrowband monochromatic light sources. A color filter for displaying colors is designed to match the wavelength of each of the monochromatic light sources so that the color filter can let a monochromatic light source of one color be transmitted, while selectively absorb the wavelengths of the monochromatic light sources of other colors. The present invention can achieve high color saturation at the backlight mode while maintaining high reflectance.

  • Patent number: 6650391
    Abstract: The present invention provides a pixel signal line module of a liquid crystal display, wherein a plurality of sub-pixels are alternately arranged in delta form on a liquid crystal display panel. A plurality of signal scan lines are used to cover and connect each transversally arranged pixel. A plurality of longitudinal data signal lines alternately shift leftwards and rightwards according to the checkered arrangement of the longitudinal sub-pixels so as to connect the sub-pixels in two adjacent longitudinal rows together in indented way. The present invention lets the signal lines be not limited by the arrangement of sub-pixels, and has the advantages of enhanced resolution, larger signal line's width, reduced impedance, and less signal distortion.
