A folding-type electronic device, such as a portable telephone, is provided with a functional component such as a switch that a user can operate regardless of whether the device is in the opened state or in the closed state, without increasing the number of parts and without expanding the mounting space. The functional component, such as a rotation switch 5, is mounted on the space between a pair of bearing mechanisms 4 that are provided between the main casing 2 and the sub-casing 3. The user can access and operate the functional component, either when the device is in an opened state or in a closed state.

The present invention provides a method of driving an active matrix display device in which one frame comprises a plurality of sub-frames each comprising a write time and a hold time and gray scale driving is brought about by the cumulative effect of the hold times. Gray scale display driving is carried out by randomly scanning scan lines other than one predetermined scan line in a predetermined sequence in the hold time of each sub-frame corresponding to the one predetermined scan line so that any one sub-frame is not written to any one scan line more than once and one frame is such that in each of the scan lines, the writings and the hold time of each of the sub-frames is ensured to bring about gray scale display. Through this means, the frame period is shortened.
