Abstract: An electronic device includes a touch sensor integrated circuit (IC) and a display driver IC. The display driver IC is configured to: obtain information for a display update, and provide, to the touch sensor IC, a first driving signal including (i) a first pulse indicating an address scan period in which the information is recorded via application of a voltage and (ii) a second pulse indicating a self-scan period in which the recorded information is maintained without application of the voltage. Furthermore, while the first driving signal is provided from the display driver IC, the touch sensor IC is configured to: perform a first operation based on detection of the first pulse, and perform a second operation based on detection of the second pulse.

Abstract: A system and a method of identifying a type of touch input to a mobile device with a touch panel are provided. The system includes a touch screen comprising a touch panel, a memory for storing information to execute a function of an application, corresponding to a touch area size and a touch interaction, and a controller. The controller identifies, when a touch is detected via the touch panel, the touch area size and the touch interaction. The controller determines information to execute a function corresponding to the identified touch area size and the identified touch interaction by referring to the memory. The controller controls a function of the application that is currently being executed.

Abstract: A method and an apparatus for improving touch sensitivity of a capacitive type touch screen panel are provided. In the method, the apparatus sequentially drives a plurality of transmitting channels of the touch screen panel using a predetermined scan frequency. The apparatus determines a sequential touch count by simultaneously scanning a plurality of receiving channels of the touch screen panel wherein the sequential touch count is the number of sequentially touched receiving channels. Also, the apparatus specifies a scan unit to be used for dividing the plurality of receiving channels into groups on the basis of the sequential touch count and for sequentially scanning the groups of the receiving channels. The apparatus determines a touch coordinate by sequentially scanning the plurality of receiving channels using the specified scan unit.
