Abstract: According to an aspect, a liquid crystal display device includes a plurality of pixels arranged in a matrix in a display area; a scanning line that is coupled with pixels arranged in a row direction in the display area and is supplied with a scan signal; a signal line that is coupled with pixels arranged in a column direction in the display area and is supplied with a pixel signal; a common electrode that is commonly coupled with the pixels and is supplied with a common voltage; and a detection circuit that detects a transient potential variation component that is synchronized with the pixel signal and is superimposed on the common voltage.

Abstract: A display device of the invention includes a display panel 10 and a touch panel 22. A detector circuit 50 has switches 411 and 412. Switches 411 and 412 are alternately turned on and off repeatedly in the setting period. Touch detection is performed during a counting period that follows the setting period on the basis of required time until a voltage at the node reaches a reference voltage while the switch 411 is turned off and switch 412 is turned on. Common voltage changes in the setting period while switch 411 is turned off and switch 412 is turned on.

Abstract: A game machine allowing a player to preferably play a game using a controller which is equipped with only a smaller number of operation members, instead of a different type of controller. A controller type determining section (40) determines a type of a controller connected to a home-use game machine. Further, the table storage section 44 stores a key assigning table for each type of a controller, showing types of operation signals input from a controller and types of actions to be performed by an operation target of the controller. A table reading section (42) reads out a key assigning table correlated with the type of a controller connected to the home-use game machine (12) from a table storage section (44).
