Ramp driver and electronic device

An electronic device comprising:

• a processor for providing an image data;
• and
• a display device for displaying an image based on the image data, and comprising:
• a display panel comprising pixels;
• and
• a ramp driver for generating ramp signals provided to the pixels, and comprising:
• a ramp generator for generating a reference ramp signal;
• and
• a ramp delayer for sequentially outputting the ramp signals based on the reference ramp signal, and comprising delay blocks comprising k output terminals, k being an integer greater than or equal to 2,
• wherein the delay blocks comprise k delay circuits sequentially connected to each other, respectively connected to the output terminals, and configured to:
• receive an input ramp signal from a previous one of the delay circuits;
• receive an input gate clock signal from a previous delay circuit;
• output an output ramp signal by delaying the input ramp signal;
• and
• output an output gate clock signal by inverting the input gate clock signal.
