Title: DISPLAY CONTROL SYSTEM, INDICATING DEVICE, AND DISPLAY PANEL
Abstract:
In this display control system (100), display control is performed in accordance with positions on a display panel (24) indicated by an indicating device (10). In said display panel (24), a pixel region is partitioned by a black matrix and a position-information pattern that represents two-dimensional positions is formed. The indicating device (10) is provided with a reading unit (15) that takes an image at an indicated position, said image including the position-information pattern. The resolution of optics (15a) in the reading unit (15) is set low such that the black matrix in the display panel (24) is removed.
