摘要: In a display device and a display driver, when a grayscale of a display image is equal to or lower than a specific grayscale value obtained from a histogram of the display image, a display grayscale is extended with a linear function. On the other hand, when a grayscale of a display image is equal to or higher than the specific grayscale value, histogram equalization of a part higher than the specific grayscale value is performed, and the display grayscale is extended with a non-linear function obtained from the histogram equalization.

摘要: A display driver driving a display panel according to inputted display data comprises: a first circuit changing brightness of a display image by conversion of the display data based on a first reference value and a second reference value, the first reference value being a display data value at a first position in an upper part of a histogram of the inputted display data, and the second reference value being a display data value at a second position in a lower portion of the histogram; a second circuit changing brightness of a illuminating device illuminating the display panel based on the first reference value; and a control circuit performing a processing of making the brightness of the display image high by the first circuit and a processing of making the brightness of the illuminating device low by the second circuit in correlation with the brightness of the display image.

摘要: Parasitic capacitances formed between bit lines to which signals are to be read out of memory cells and a signal transmission line arranged above them are to be reduced. Second complementary global bit lines for transmitting data read out of memory cells MC via complementary bit lines are arranged above a memory cell array. Each second global bit line is so arranged that a triangle having as its vertexes the center of the section of one of the complementary bit lines, that of the section of the other and that of the section of the second global bit line arranged directly above these complementary bit lines be an isosceles triangle.
