ABSTRACT:
In a simplified user switching function for switching to another user without terminating an application of a current user, data of an application started up a user before switching is included and temporarily stored in a temporary storage file. Data generated by using an application started up a user A who is currently inactive as a result of user switching (user being in a logged-on state but the desktop changed to that of another user) is stored temporarily at the time of the user switching. Thus, even when a user B (currently active user) after the user switching performs a shutdown operation or the like, the data of the currently inactive user A can be protected securely. Also, when the writing time is set unchanged, transistor size of the TFTs provided in the pixel circuit can be reduced.
