<p><P>PROBLEM TO BE SOLVED: To provide a display control circuit regulating a lightness of a display screen (display brightness), irrespective of amplitude regulation of a common signal voltage, and to provide a display provided therewith. <P>SOLUTION: A display reference data serving as a reference is prepared from a display data, in response to a supplied lightness set value, by a display reference data preparing circuit 184, to be stored in a display reference data register 185, the display reference data is shifted to be held as a display shift data in a display shift data register 186, and the display reference data stored in the display reference data register 185 and the display shift data held in a display shift data register 186 are selected synchronizedly with a vertical synchronization signal, in response to a difference between the lightness set value and a lightness reference set value, by a display data selection signal preparing circuit 187, to be output from a selector 188 to a source driver 130. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
