Description

금속 산화물을 포함하는 디스플레이용 분산액 조성물의 제조방법{SOL DISPERSION FOR DISPLAY DEVICE COMPRISING METAL OXIDE} TECHNICAL FIELD [0001] The present invention relates to a dispersion composition for a display comprising a metal oxide,

본 발명은 디스플레이용 필름 등의 제조에 이용되는 금속 산화물 졸 및 그 제조방법에 관한 것이다.The present invention relates to a metal oxide sol used for producing a film for display and the like, and a process for producing the same.

금속류의 산화물을 포함하는 조성물은 디스플레이용 필름 등을 제조하는데 있어서 유용하게 이용되고 있다. 이러한 디스플레이용 필름 중 일 예로 휘도(輝度)향상 필름 (brightness enhancing film)이 있다. Compositions containing oxides of metals are usefully used in the manufacture of display films and the like. One example of such a display film is a brightness enhancing film.

이러한 디스플레이용 필름은 전자발광 패널, 랩탑컴퓨터 디스플레이, 워드프로세서, 데스크탑 모니터, 텔레비전, 비디오 카메라 및 자동차용 및 항공기용 디스플레이 등에 있어서 액정 모니터 (LCD)등의 백라이트식 플랫 패널 디스플레이의 휘도(輝度)를 증가시키기 위한 목적 등으로 이용되고 있다.Such a display film can be used as a backlight flat panel display such as a liquid crystal monitor (LCD) in an electroluminescent panel, a laptop computer display, a word processor, a desktop monitor, a television, a video camera, And the like.

이와 같은 디스플레이용 필름을 이용하면, 굴절율을 포함하는 특정한 패널 표면에서의 광학적 특성 및 물리적 특성을 바람직하게 향상시킬 수 있다. 일 예로서, 휘도 향상 필름 등을 구비할 경우, 휘도(輝度)의 개선에 의해, 더 적은 전력을 사용해서 디스플레이를 조명할 수 있고, 그것에 의해서 전력 소비를 저감하고, 발열의 정도가 저하되고 제품의 수명이 연장되어, 전자제품을 보다 효과적으로 사용하게 될 수 있다. By using such a display film, it is possible to preferably improve optical characteristics and physical properties on a specific panel surface including refractive index. As an example, when a brightness enhancement film is provided, the display can be illuminated by using less power due to improvement in brightness (luminance), thereby reducing power consumption, reducing the degree of heat generation, So that the electronic product can be used more effectively.
