Title:
FILM TOUCH SENSOR
Document Type and Number:
WIPO Patent Application WO/2018/016811
Kind Code:
A1
Abstract:
The present invention relates to a film touch sensor. The present invention comprises: a separation layer; a first protection layer that is formed on the separation layer; a touch detection layer that is formed on the first protection layer; a second protection layer that is formed on the touch detection layer; and an optical compensation layer that is formed between the first protection layer and the touch detection layer, or between the touch detection layer and the second protection layer, and that compensates for a transmittance difference between a pattern region in which a transparent electrode pattern forming the touch detection layer is formed, and a non-pattern region in which the transparent electrode pattern is not formed. According to the present invention, by compensating for the transmittance difference between the pattern region forming the touch detection layer and the non-pattern region, these regions are prevented from being visually distinguished, light transmittance through the pattern region is improved, and thereby the image quality can be improved.
