본 발명은 발광소자 및 그 제조방법에 관한 것으로서, p-형 고분자 입자들 주위에 엑시톤 결합 센터인 진성(intrinsic) 반도체 나노결정들이 균일하게 등방적 분포되고 그 주위를 n-형 저분자 입자들이 둘러싸는 pin 구조의 단일 활성층을 가지는 교류 전압 구동형 발광소자 및 그 제조방법에 관한 것이다. 본 발명의 발광소자에서는 고분자-반도체 나노 복합체를 이용한 핵-껍질 구조의 활성층이 정방향과 역방향의 전압 인가시에 같은 전류-전압 특성을 보이는 역대칭(inversion symmetry) 특성을 가진다. 따라서, 이러한 역대칭 특성에 의해 본 발명의 발광소자는 교류 전압으로 구동이 가능하다. 또한 교류 전압을 사용하여 구동될 수 있으므로, 기존의 직류 전압 구동형 유기물 발광다이오드가 가지는 문제점, 즉 과전류(overcurrent)에 의한 소자의 파괴 또는 결함, 국부적인 구성 유기 물질의 퇴화에 의한 다크 스폿(dark spot)의 생성 등의 문제점이 해결된다. 핵, 껍질, 고분자, 반도체, 나노, 복합체, 양자점, 일체형, 역대칭, 교류 구동, 발광소자, 발광다이오드, 단일 활성층, 투명전극, 양방향 전계 방출

PURPOSE: A transparent touch panel and a manufacturing method using a piezoelectric substrate are provided to form a patterned transparent oxide layer which is deposited on a compliant piezoelectricity macromolecular film, thereby realizing a touch panel with a simple structure. CONSTITUTION: An insulating layer(202) is formed on a display layer(200). A piezoelectric substance substrate(204) is formed on the insulating layer by a PVDF film. A transparent conductive layer(206) is formed on a section or both sides of the PVDF film. A location is measured by sensing an electric potential difference signal generated to which pressure is applied on the transparent conductive film. A touch panel layer is made by forming the transparent conductive layer formed with channels and a transparent insulating layer(208) on the piezoelectric substance substrate.
