Patent ID: 8791965

Claim:
A display drive circuit that performs digital driving for displaying an image of each one frame based on luminance data of a plurality of subframes, the display drive circuit comprising: a generation section that generates, based on gradation data, the luminance data having a plurality of bits indicating a luminance level of each of the plurality of subframes: a conversion section that converts the luminance data into data indicating the luminance level in a number greater than the number of the plurality of subframes; and a storage section that stores the data converted by the conversion section, wherein the conversion section is equipped with a plurality of conversion circuits that alternately perform input of data generated by the generation section and output of converted data, and each conversion circuit includes: a plurality of shift registers that operate in synchronism with each other, and each having an input terminal in which each bit value of the data generated by the generation section is inputted, and output terminals in a number of bits of data to be outputted; a plurality of selectors, each having input terminals in the number of bits of data generated by the generation section wherein the input terminals are connected to the output terminals with identical shift stage numbers among the output terminals of the plurality of shift registers, respectively; and a counter that controls data to be selected by the plurality of selectors.
