Patent ID: 7154467

Claim:
A control circuit of a liquid crystal display device, comprising: a display driving data generation section for generating display driving data corresponding to a combination of image data of a current frame and post driving status data of a previous frame, wherein said display driving data generation section further comprises: a conversion table for storing compensation data or compensation display driving data corresponding to a combination of significant bits of the image data of the current frame and of the post driving status data of the previous frame; and an interpolation operation section for generating interpolation compensation data or interpolation compensation display driving data by performing an interpolation operation for the compensation data or the compensation display driving data which is read from said conversion table according to insignificant bits of said image data of the current frame and of the post driving status data of the previous frame, said conversion table including a singular point conversion table used when the post driving status data of the previous frame is a first data, and an ordinary point conversion table used when the post driving status data of the previous frame is other than said first data, and said display driving data generation section selecting either said singular point conversion table or said ordinary point conversion table depending on whether the post driving status data of the previous frame is the first data.
