Abstract
A character display control circuit comprises a selection circuit to select and output, as one of the RGB signals, one of a first voltage, a second voltage lower than the first voltage, and one or more third voltages existing between the first and second voltages; a holding circuit in which first data, consisting of a plurality of bits, for the selection circuit to select and output one of the first, second, and third voltages, is set in response to display timings of the display characters; and a selection control circuit to supply the selection circuit with selection signals for the selection circuit to select and output one of the first, second and third voltages depending on the first data, second data associated with the selection of the first voltage or the second voltage, and third data associated with the selection/unselection of the third voltages.
