Abstract
A liquid ejecting apparatus includes a control circuit substrate that outputs a head control signal for use in controlling an ejection head to a head circuit substrate. The control circuit substrate includes a first buffer circuit having a first buffer and a second buffer. The first buffer circuit can simultaneously write first image data contained in the base image data signal into the first buffer and read second image data contained in the base image data signal from the second buffer. The first buffer circuit writes the first image data into the first buffer at a first frequency and reads the first image data from the first buffer at a second frequency, which is higher than the first frequency. The first buffer circuit writes the second image data into the second buffer at the first frequency and reads the second image data from the second buffer at the second frequency.
