摘要： A decoder circuit which outputs a voltage based on a 8-bit digital value includes: a first decoder circuit and a second decoder circuit which output one voltage respectively using upper-order 6 bits of the 8-bit digital value; a selection circuit which receives voltages outputted from the first decoder circuit and the second decoder circuit, and distributes the two voltages to three terminals; and an intermediate voltage output circuit which outputs an intermediate voltage which is a one of five kinds of values based on the three voltages. The first decoder circuit and the second decoder circuit respectively include a select-switch-type decoder circuit and a tournament-type decoder circuit. Due to such a constitution, it is possible to reduce a circuit scale of the decoder circuit which outputs the voltage corresponding to the 8-bit digital value.

摘要： In a display device, profile emphasizing is performed without using a frame memory while realizing the further reduction of power consumption. A display device includes a display panel provided with a plurality of pixels each of which has a pixel electrode, and a drive circuit which supplies a video signal to the respective pixels through video lines. Here, the drive circuit includes a profile emphasizing circuit which generates profile emphasizing display data which emphasizes a profile in response to display data inputted from the outside and emphasizes a profile portion of an image to be displayed on the display panel, and a memory which stores the profile emphasizing display data. The profile emphasizing circuit includes a latch circuit which sequentially stores continuous k (k≧2) pieces of display data in display data for 1 display line and an arithmetic circuit which generates the profile emphasizing display data based on the k pieces of display data stored in the latch circuit.
