ABSTRACT:
A driving device includes (i) a switching circuit, which carries out precharging by (a) separating an outputting circuit from source signal lines, and (b) short-circuiting at least one source signal line whose source signal potential is positive in a certain horizontal period and at least one source signal line whose source signal potential is negative in the certain horizontal period and (ii) a pulse width adjusting circuit which adjusts timings. Therefore, it is possible to carry out a charge sharing without additionally providing an external memory capacitor. On this account, even when a newly designed display section (liquid crystal panel, etc.), which is different in the number of pixels and materials from a conventional display section, is used, it is possible to realize a display device and a driving device which do not require the change in the arrangement of the controller.
