SEMICONDUCTOR DEVICE AND DISPLAY DEVICE

摘要

The semiconductor device includes: a display panel (e.g. a liquid crystal display panel) which has a capacitor for holding an electric charge corresponding to image data in quantity in each pixel and displays image data of each frame made up of lines; and a display-drive circuit for activating the display panel. The display-drive circuit performs a time-division action in which a one-frame period includes display-drive periods in which the display panel is activated, and blank periods in which the activation of the display panel remains stopped, which are arranged alternately. The display-drive circuit drives, for display, lines of one frame which are almost evenly distributed to display-drive periods in groups of several lines.

主权项

1. A semiconductor device comprising:
a display-drive circuit operable to output drive signals for activating a display panel operable to display image data of each frame made up of a plurality of lines each composed of pixels, wherein the display panel has, in each pixel of pixels constituting the lines, a capacitor for holding an electric charge corresponding to the image data in quantity, the display-drive circuit is capable of performing a time-division action arranged so that a first display-drive period, a first blank period, and a second display-drive period are included in one frame period in turn, and the display-drive circuit is arranged to be able to output the drive signals for: driving, in the first display-drive period, lines of the display panel in one frame which are distributed with a predetermined cycle; stopping activating the display panel in the first blank period; and driving, in the second display-drive period, lines of the display panel different from the lines driven for display in the first display-drive period in the one frame.
