Abstract
A liquid crystal display is provided, including a conversion circuit to convert a first image data to a second image data, a frame memory to store the second image data, a difference circuit to output in units of pixel a difference data between the second image data of the present frame to be converted and a third image data of an antecedent frame to be outputted from the frame memory, a correction circuit to correct the difference data based on one of the first to third image data, and an adding circuit to add the corrected difference data and the first image data.
Claims18
A liquid crystal display, comprising:
- a conversion circuit to convert a first image data to a second image data having a fewer number of bits than said first image data;
- a frame memory to store the second image data;
- a difference circuit to output in units of pixel a difference data between the second image data of a present frame and a third image data of an antecedent frame outputted from said frame memory;
- a correction circuit to change said difference data based on one of the first to third image data;
- and
- an adding circuit to add the difference data which is changed and the first image data, wherein
- said conversion circuit maps the first image data nonlinearly to the second image data in irregular intervals.
