However, in this method, even in the case where the initial touch area is small, the touch area is enlarged as the touch force increases, and, when a bit touch or proximity touch is applied to the touch panel, the touched area cannot be The area of is distinguished from the touch area formed by force touch
[0006] For this reason, in the prior art touch panel for sensing force touch, it is difficult to accurately determine the user's force touch

An apparatus for driving a touch panel can include a touch panel for sensing a force touch of a user input, and a touch driver for sensing the force touch from the touch panel and generating touch force data, in which the touch driver adjusts a sensitivity of the touch force data, based on touch mode information set by the user.
Description
technical field [0001] The present invention relates to an apparatus for driving a touch panel that senses a force touch and a touch position, and an electronic device including the apparatus. Background technique [0002] In addition to portable electronic devices such as electronic notebooks, electronic books, portable multimedia players (PMP), navigation devices, ultra mobile personal computers (UMPC), mobile phones, smart phones, tablet personal computers (PC), watch phones, mobile communication terminals, etc. In addition to devices, touch panels are also used as input devices for various products such as televisions (TVs), notebook computers, monitors, and the like. [0003] Recently, as user interface environments for applications requiring touch information related to force touch are established, electronic devices for sensing force touch are being used. [0004] In related art touch panels for sensing force touch, a force sensing material is disposed between upper ...
