MULTI-SCREEN DISPLAY DEVICE, MULTI-SCREEN DISPLAY DEVICE DRIVE METHOD, AND MULTI-SCREEN DISPLAY SYSTEM

摘要

In the present invention, the position coordinates of a light pen (50) are detected with reduced error. In order to do so, provided is a multi-screen display device (130) in which a plurality of partial image display devices (30a, 30b, 30c, 30d) are arranged in a matrix shape, wherein for two partial image display devices disposed next to each other, at least one ofthe movement direction of a first emission line when a y-coordinate detection pattern is displayed on an image display unit in a y-coordinate detection subfield, or the movement direction of a second emission line when an x-coordinate detection pattern is displayed on an image display unit in an x-coordinate detection subfield, is made the opposite of the other.
