Abstract
A dot-matrix display device includes a display, a converter circuit, and a control circuit. The display includes multiple gate signal lines, multiple source signal lines, and multiple pixel circuits arranged at intersections of the multiple gate signal lines and source signal lines. The converter circuit obtains a serial signal SI in synchronization with a first clock signal SCK input from outside and converts the obtained serial signal to a parallel signal. The serial signal is input from outside serially. The serial signal includes address data for specifying, of the multiple pixel circuits, a pixel circuit to undergo a refresh of image data, and the image data to be provided to the specified pixel circuit. The control circuit generates, based on a second clock signal ENB_V having a lower frequency than the first clock signal, a control signal for controlling timing of serial-to-parallel conversion performed by the converter circuit.
