Abstract

An LCD with touch-control function, including an alternating signal generating circuit, a timing control circuit, a first sensing circuit, a voltage signal generating circuit, and a second sensing circuit. In this case, the alternating signal generating circuit is used for generating an alternating signal. The timing control circuit controls the alternating signal generating circuit to charge the alternating signal into a counter electrode panel during the idling time in-between the writing periods in which the scan lines turn on sequentially to write the image data into the LCD screen. The first sensing circuit detects the magnitude of the coupled signal of each of the scan lines that need to be detected, and detects the touch position in the scan line direction according to such magnitudes. After the touch position of the scan line direction has been detected, the voltage signal generating circuit controlled by the timing control circuit generates a voltage signal and inputs the voltage signal to each of the data lines which need to be detected. After the voltage signal being inputted to the data lines, the second sensing circuit detects the magnitude of the coupled signal of each of the data lines that need to be detected, and detects the touch position in the data line direction according to such magnitudes. Furthermore, this invention also discloses a touch-control method for the mentioned LCD.

[Background of the Invention] Field l-jg: The description of technology is old since it is familiar with touch panel (touch panel) technology. Capacitive touch screen, pen touch 2 Screen, resistive touch screen, etc. Among them, the capacitive touch screen (also called capacitive touch panel) is based on human touch technology, which is mainly used in banks 'ATM machines, automatic H', Voucher and other systems. The pen-type touch screen is an extension of the above-mentioned capacitive touch screen technology, which can sense the touch of a hand or a special stylus, and can be set to fingervnly or pen-based ⑶ οη1Z) β, three kinds of induction modes (both) and other induction modes. Resistive touch screens are pressure-sensitive, so there are no restrictions on the touch medium. Generally, this type of resistive touch screen forms a poly-lipid material layer on the upper surface of its structure as a top-sheet. The inner layer of the upper surface layer is formed with a transparent conductive layer, and is isolated above a glass plate formed with a transparent conductive layer by a fine spacer. Therefore, when a current is passed through the upper surface layer, if used, If the upper surface layer is pressed, the multi-component grease and the conductive layer on the glass plate will contact each other, so that current flows to the four corners of the touch screen. At this time, a controller reads the four corners at the same time. The coordinates of the touch point can be calculated by the current value.
