DISPLAY PANEL AND DISPLAY CONTROL SYSTEM

摘要

PROBLEM TO BE SOLVED: To avoid superposition of a shadow of a grid structure on a received image of a position information pattern read by a reading device and decipher position coordinates with more accuracy.SOLUTION: A display panel forms a display control system with an optical pen. The display panel includes: a position information pattern layer that is formed according to a given law so as to cause the optical pen to specify position information designated by the optical pen on the display panel; a color filter layer in which a color filter sectioned by a grid structure is disposed; and an invisible light reflection layer that reflects at least a part of invisible light ejected from the optical pen to the optical pen through the position information pattern layer. The invisible light reflection layer is disposed between the position information pattern layer and the color filter layer.SELECTED DRAWING: Figure 1
