摘要： An in-cell capacitive touch panel is disclosed. The present invention utilizes a sensing unit that comprises a sensing liquid crystal capacitor and three transistors to detect touch events. A first transistor is connected to a first gate line and the sensing liquid crystal capacitor and controlled by the first gate line to charge the sensing liquid crystal capacitor. A second transistor together with a third transistor functions as a capacitance-current converter. The second transistor generates an output current according to the voltage of a first electrode of the sensing liquid crystal capacitor. A second gate line controls the third transistor to transfer the output current through a readout line to a readout unit that determines the touch positions. Thus, the in-cell capacitive touch panel of the present invention can use a simple-structure readout circuit to achieve superior readout accuracy and is adaptive to various sizes of touch panels.

The voltage produced by the counter electrode is able to affect a conductivity of the channel of the inducing element corresponding to the touched position. The inducing element and a readout circuit are disposed on a substrate of the display device. The counter electrode and a shielding element are both corresponded to the inducing element. The channel of the inducing element corresponding to the touched position changes the conductivity due to the voltage produced by the corresponding counter electrode, and an inducing signal is then generated. The inducing signal is furnished to the readout circuit for signal processing, and a readout signal is generated for analyzing the touched position.

摘要： A multi-touch detecting method is adapted for detecting locations of touched points on a touch panel including first and second conductive films, and includes following steps. First measuring points of the first conductive film distributed along X-axis of a Cartesian plane are scanned, and x-components are determined accordingly. Second measuring points of the second conductive film distributed along Y-axis of the Cartesian plane are scanned, and y-components are determined accordingly. A first voltage is applied to the first conductive film, and A second voltage is applied to at least one of the second measuring points with the location on the Y-axis adjacent to or overlapping one of the y-components. Voltages at the first measuring points with the locations on the X-axis adjacent to or overlapping the x-components are measured sequentially and one of the y-components and one of the x-components are outputted.

摘要： A liquid crystal display is provided. A pixel of the liquid crystal display includes a first pixel capacitor, a second pixel capacitor, a first transistor, and a second transistor. A first terminal and a second terminal of the first pixel capacitor are respectively coupled to the first transistor and a common voltage. A first terminal and a second terminal of the second pixel capacitor are respectively coupled to the second transistor and the common voltage. A voltage between the first and the second terminals of the first capacitor is differentiated from a voltage between the first and the second terminals of the second capacitor by modulating the common voltage. A coupling voltage of the first pixel capacitor is differentiated from a coupling voltage of the second pixel capacitor by modulating the common voltage. Thereby, the phenomenon of color wash-out is reduced.
