Display device and display control system

摘要

A display device 2 includes: a display panel 50 having a display area; and a plurality of position information patterns 3 arranged on the display area and each representing information regarding a position thereof on the display area. Each position information pattern 3 is formed of a plurality of optically readable marks 31 that are formed from a material that transmits visible light. On the display area, a plurality of sub-pixels 5R, 5G, and 5B whose colors are different from each other are repeatedly aligned in a determined alignment direction. A length L between both ends of the mark 31 in the alignment direction meets a relational expression of n×P+w≦L≦(n+1)×P−w (n is an integer of 0 or greater) where a width of the sub-pixel in the alignment direction is w and a pitch between the pixels 5 in the alignment direction is P.

1. A display device comprising:
a display panel having a display area on which a plurality of pixels each including a plurality of sub-pixels whose colors are different from each other are arranged in a matrix manner; and a plurality of position information patterns arranged on the display area and each representing information regarding a position thereof on the display area, wherein each position information pattern is formed of a plurality of optically readable marks that are formed from a material that transmits visible light, on the display area, the plurality of sub-pixels whose colors are different from each other are repeatedly aligned in a determined alignment direction, and a length L between both ends of the mark in the alignment direction meets a relational expression of n×P+w≦L≦(n+1)×P−w (n is an integer of 0 or greater) where a width of the sub-pixel in the alignment direction is w and a pitch between the pixels in the alignment direction is P.
