  • Patent number: 9389744
    Abstract: Provided are a resistive touch panel detection method and apparatus. A resistance variance ratio of a Y plane relative to an X plane is calculated based on voltage detections before touching and after a two-point touch occurs; and then the inclination angle is calculated based on corresponding relationship between the inclination angle and the resistance variance ratio. To obtain a distance between the two points, the present invention the resistance variance ratio and a first ratio of a resistance variance of any one of the X plane and the Y plane relative to a total resistance of the any one plane are calculated; then a second ratio of an equivalent contact resistance at a midpoint relative to the total resistance is calculated; and the distance is calculated based on the resistance variance ratio, the first ratio, the second ratio, and a correlated relationship of the distance between the two points.

  • Publication number: 20140210769
    Abstract: A scanning method, apparatus, controller and electronic device based on an in-cell technique is provided according to the embodiments of the present invention. The scanning method includes: scanning a first region of a liquid crystal display (LCD) during a first period of a scanning cycle; scanning the full screen of a capacitive touch panel (CTP) during a second period of the scanning cycle; scanning a second region of the LCD during a third period of the scanning cycle. By scanning at least two regions of the LCD in a time-sharing manner and by scanning the CTP and the LCD alternatively, according to the embodiments of the present invention, the technical effect of scanning the LCD and the CTP uniformly can be achieved, in the case that there is not the without mutual interference between the scanning of the LCD and the scanning of the CTP.
