摘要： A method and device for position detection are disclosed. A self-capacitance detection can be performed by a sensing device. According to the result of the self-capacitance detection, a first mutual-capacitance detection can be performed for determining one or more first 1-D positions. According to the result of the first mutual-capacitance detection, a second mutual-capacitance detection can be performed for determining one or more second 1-D positions corresponding to each first 1-D position. One or more 2-D positions can be provided according to the one or more second 1-D positions corresponding to each first 1-D position. Besides, during the self-capacitance detection, the first mutual-capacitance detection, and the second mutual-capacitance detection, a touch related sensing information corresponding to a touch that covers a wide area can be neglected for palm rejection.

摘要： The present invention provides a mutual capacitive multi-touch screen. The conductive strip pattern allows that, when a touch range of each external conductive object on the mutual capacitive multi-touch screen is larger than a predetermined condition, capacitive coupling between each external conductive object and first conductive strip is greater than capacitive coupling between each external conductive object and second conductive strip, such that the proportion of a driving signal flowing out of the first conductive strip via at least one first external conductive object in the external conductive objects and into the second conductive strip via at least one second external conductive object in the external conductive objects decreases as the number of second external conductive objects increases.

摘要： Described is a device and a method for determining a touch position on a sensing area of a capacitive touch panel. In the device and method, an alternating current (AC) scan signal having a frequency and a current value is supplied to each of four corners of the capacitive touch panel. Next, the frequencies of the AC scan signals are each rapidly switched among a group of specific frequencies. The current values of the AC scan signals detected. In response, a group of selected frequencies is selected according to a noise filtering procedure from the group of specific frequencies based on the current values. Final current values are obtained by calculating the current values of the AC scan signals of the group of selected frequencies. Finally, the touch position on the capacitive touch panel is determined based on the final current values.

摘要： A charge pump includes a chip and a package substrate packaged on the chip and installed in a circuit board. One of the 1st˜(X−Y)th external pins of the package substrate is electrically connected to the (X−Y)th input pin of the chip, and the other end of the same external pin is electrically connected to the input voltage of the circuit board. Thus, when the input voltage is being boosted through each capacitor of the circuit board, it is free from the action of the 1st through (X−Y−1)th transistors of the chip and therefore the original design of the 1st through (X−Y−1)th transistors can be maintained without causing any change in the output voltage Thus, the invention eliminates the problem of the prior art design that needs to change the internal circuit design when a different output voltage is required.
