ABSTRACT:
A display device for displaying images based on video signals includes a timing signal generating circuit for generating a timing signal, a sampling signal generating circuit for generating a sampling signal at the timing corresponding to the timing signal, and a sampling circuit for sampling a target signal during a sampling period set by the sampling signal and outputting the sampled target signal. The sampling circuit is connected to the timing signal generating circuit so that test output obtained by sampling a test target signal during the sampling period set by the sampling signal corresponding to a test timing signal generated by the timing signal generating circuit can be input into the timing signal generating circuit, and the timing signal generating circuit controls the relative output timing between the timing signal and the target signal under the control based on the test output input.
