DISPLAY CONTROL SYSTEM AND READING DEVICE

摘要

In a display control system, a reading device includes a light source and an imaging optical system configured to capture an image of light, and a display panel includes: an information pattern layer; and a reflection layer configured to diffusely reflect the light from the light source. The light source is arranged at a position other than a position on an optical axis of the imaging optical system. In a state where the optical axis of the imaging optical system is perpendicular to the reflection layer and the reading device is in contact with the display panel, a point at which a central light beam of the light emitted from the light source reaches the reflection layer is located at the light source side of a point at which the optical axis of the imaging optical system intersects the reflection layer.

1. A display control system comprising:
a display panel configured to display an image; and a reading device configured to optically read an information pattern formed in the display panel, wherein the reading device includes:
at least one light source configured to emit light toward the display panel; andan imaging optical system configured to capture an image of the light that has been emitted from the light source and reflected by the display panel, the display panel includes:
an information pattern layer in which the information pattern is formed; anda reflection layer arranged at a back side of the information pattern layer and configured to diffusely reflect the light from the light source, the light source is arranged at a position other than a position on an optical axis of the imaging optical system, and in a perpendicular contact state where the optical axis of the imaging optical system is perpendicular to the reflection layer and the reading device is in contact with the display panel, a point at which a central light beam of the light emitted from the light source reaches the reflection layer is located at the light source side of a point at which the optical axis of the imaging optical system intersects the reflection layer.
