摘要

A vertical area specifying circuit (141) outputs a vertical area specifying signal according to vertical display position information, the vertical synchronizing signal, and horizontal synchronizing signal to a vertical driver (103). A horizontal area specifying circuit (142) outputs a horizontal area specifying signal according to horizontal display position information, the pixel synchronizing signal, and the vertical and horizontal synchronizing signals to a horizontal driver (102). The horizontal driver (102) outputs the inputted video signal to a video display surface (101) through the signal line at the horizontal coordinate corresponding to the number of pixel synchronizing signals counted from the timing when the horizontal synchronizing signal is inputted while the horizontal area specifying signal is effective. The vertical driver (103) holds the number of synchronizations of the horizontal synchronizing signal while the vertical area specifying signal is effective and selects the signal line at the vertical coordinate corresponding to the number of synchronizations. Displayed on the video display surface (101) is the video signal outputted from the horizontal driver (102) in the position specified by the horizontal coordinate corresponding to the signal line through which the video signal is outputted and by the vertical coordinate corresponding to the signal line selected by the vertical driver (103).
