Abstract
A method of operating a display driver IC (DDI) includes comparing previous line data with current line data and the R, G, and B components of a color data signals, and controlling whether to activate part of an intermediate processing circuit to process the current line data or more than a single component of the color data signal according to a comparison result.
Claims21
A method of operating a display driver IC (DDI), the method comprising:
- comparing previous line data with current line data;
- controlling whether to activate part of an intermediate processing circuit to process the current line data according to a comparison result;
- processing the previous line data using the intermediate processing circuit and transmitting processed previous line data to a data latch;
- and
- outputting the processed previous line data as output data corresponding to the current line data when it is found that the previous line data is the same as the current line data as the comparison result.
2 more elements
A display driver IC (DDI) comprising:
- a storage circuit to store previous line data and current line data;
- an intermediate processing circuit to process the current line data;
- and
- a line data comparing circuit to compare the previous line data with the current line data and to generate a comparison signal to control whether to activate the intermediate processing circuit according to a comparison result.
1 more element
A method of operating a display driver IC (DDI), the method comprising:
- comparing color data signals constructing display data with each other and detecting a gray pattern;
- and
- controlling whether to activate part of an intermediate processing circuit to process the color data signals according to a detection result.
