Abstract
The display control system performs display control according to a position indicated by a pointer on a display panel. The display panel includes pixel regions defined by a black matrix, and a positional information pattern showing a plan position is formed in the display panel. The pointer includes a reader configured to capture an image which is at the indicated position and includes the positional information pattern. The optical system of the reader is formed to have a low resolution so that the black matrix of the display panel is removed.
