Title (EN) FILM TOUCH SENSOR
(FR) CAPTEUR TACTILE À FILM
(KO) 필름 터치 센서
Abstract:
(EN) 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.
(FR) La présente invention porte sur un capteur tactile à film. La présente invention comprend : une couche de séparation ; une première couche de protection qui est formée sur la couche de séparation ; une couche de détection tactile qui est formée sur la première couche de protection ; une seconde couche de protection qui est formée sur la couche de détection tactile ; et une couche de compensation optique qui est formée entre la première couche de protection et la couche de détection tactile, ou entre la couche de détection tactile et la seconde couche de protection, et qui compense une différence de transmission entre une région de motif dans laquelle un motif d'électrode transparent formant la couche de détection tactile est formé, et une région de non-motif dans laquelle le motif d'électrode transparent n'est pas formé. Selon la présente invention, en compensant la différence de transmission entre la région de motif formant la couche de détection tactile et la région de non-motif, ces régions ne peuvent pas être distinguées visuellement, la transmission de lumière à travers la région de motif est améliorée, et la qualité d'image peut ainsi être améliorée.
(KO) 본 발명은 필름 터치 센서에 관한 것이다. 본 발명은 분리층, 상기 분리층 상에 형성된 제1 보호층, 상기 제1 보호층 상에 형성된 터치 감지층, 상기 터치 감지층 상에 형성된 제2 보호층 및 상기 제1 보호층과 상기 터치 감지층 사이 또는 상기 터치 감지층과 상기 제2 보호층 사이에 형성되어 있으며, 상기 터치 감지층을 구성하는 투명전극 패턴이 형성되어 있는 패턴 영역과 상기 투명전극 패턴이 형성되어 있지 않은 비패턴 영역 간의 투과율 차이를 보상하는 광학 보상층을 포함한다. 본 발명에 따르면, 터치 감지층을 이루는 패턴 영역과 비패턴 영역 간의 투과율 차이를 보상하여 이들 영역이 구별되게 시인되는 현상을 방지하고 패턴 영역을 통한 광 투과율을 향상시켜 영상 품질을 향상시킬 수 있다.
