摘要： A frame memory 105 stores the original image data received from a higher-level device 102 via an interface 103. Color reduction processing means receives color reduction rate data through a transfer from an upper-level device 102 or manual setting means such as a switch or jumper settings. Based on this color reduction rate data, the number of colors in the gradation data of the original image is reduced, and the color count of the original image is simulated using the reduced color count. Also included are a timing generating circuit 106 and a gradation voltage generating circuit 107. A gradation voltage selector 108 performs a partial halting of driver operations based on the color reduction rate.

摘要： A display driver for outputting gradation voltages corresponding to gradation data from an external device to pixels. The display driver includes a generator for generating a plurality of gradation voltages having a plurality of levels based on a reference voltage, and a selector for selecting at least one gradation voltage corresponding to the gradation data from the plurality of gradation voltages generated by the generator. The gradation data includes multi-bits for each color of red, green and blue, and the generator outputs or stops outputting each gradation voltage according to data for color reduction from the external device. The generator stops outputting at least one gradation voltage that is unnecessary for displaying as a result of the color reduction, when the color of the gradation data is reduced according to the data for color reduction.
