    Abstract: A touch panel threshold pressure setup method and apparatus. In this touch panel threshold pressure setup method, at first multiple touches are performed when the setup is run, and with this, the multiple pressure values can be obtained. Then, the obtained pressure values are averaged to obtain an average pressure value. Finally, the average pressure value itself or a value obtained from a certain multiplier multiplied by the obtained average pressure value is used as a threshold pressure value. Moreover, the pressure value mentioned above can be represented by the contact resistance value if the resistance type touch panel is used. However, the pressure value is inverse proportional to the contact resistance value that represents it.
