Abstract:
1. A display device comprising: a display panel; a drive circuit driving respective pixels of the display panel; and a control circuit supplying display data to the drive circuit, wherein the control circuit includes a random number generating circuit, the random number generating circuit includes an output circuit which increases a frequency of a pulse signal generated by the random number generating circuit n times, where n is an integer greater than one, and outputs a pulse signal of n-times increased frequency, the random number generating circuit includes n pieces of shift registers, a basic clock for n pieces of shift registers is an intermittent drive clock which intermittently alternates between a clock stopping period during which the random number generating circuit stops generating a random number and a clock outputting period, the basic clock being configured to controllably adjust an intermittent period thereof so as to control a level of radio waves generated by the random number generating circuit, and the control circuit outputs an inversion control signal indicative of inversion of the display data.
