DISPLAY FILTER HAVING TOUCH INPUT FUNCTION

摘要

PROBLEM TO BE SOLVED: To provide a display filter to be used as a display filter and for touch input.

SOLUTION: The display filter having a touch input function includes a base substrate; a conductive film coating layer formed on the base substrate; a touch sheet which is arranged with an air gap from the conductive film coating layer, and brought into contact with the conductive film coating layer by an external touch pressure; a first electrode which is formed on a surface of the touch sheet that faces the conductive film coating layer, the first electrode including a first electrode part to which a first input voltage is applied to generate x-directional potential distribution on the touch sheet and a second electrode part to which a second input voltage is applied to generate y-directional potential distribution; and a second electrode which is formed on the periphery of the conductive film coating layer to supply electrical current when the touch sheet is in contact with the conductive film coating layer.
