Abstract
Description
본 발명은 고온 신뢰성 및 내열성이 우수한 디스플레이용 투명부재에 관한 것이다.The present invention relates to a transparent member for a display excellent in high-temperature reliability and heat resistance.
전자 기술의 발전에 따라 다양한 디스플레이 장치가 개발되고 있다. CRT, LCD, PDP, OLED 등과 같이 다양한 디스플레이 부품을 포함하는 디스플레이 장치들이 사용되었거나 사용되고 있다. 그러나, 기존의 디스플레이 장치들은 디스플레이부가 배치된 일 방향에서 시청할 수 밖에 없는 한계를 가지고 있었다. 이러한 한계를 극복하기 위해 투명 디스플레이 장치에 대한 연구가 진행되고 있다.Various display devices have been developed in accordance with the development of electronic technology. Display devices including various display parts such as CRT, LCD, PDP, and OLED have been used or used. However, existing display devices have limitations that can only be viewed in one direction in which the display unit is disposed. In order to overcome these limitations, researches on transparent display devices are under way.
투명 디스플레이 장치는 디스플레이부가 투명하기 때문에 사용자가 디스플레이부에 표시되는 컨텐츠와 함께 디스플레이부 뒷면의 피사체를 함께 볼 수 있는 장점이 있다. 이러한 LED 등의 디스플레이용 투명부재의 기존 재료는 Yellow 파장대를 흡수하는 재료는 많으나 입자 Size가 커 휘도 저하가 크게 발생하고 또한 유기 안료를 사용하여 고온 신뢰성 및 색순도 유지가 어려운 단점이 있었다. 또한 투명 기판을 PC, PVC, PET를 사용하는 경우에도, 이와 같은 필름은 그 내열특성이 COB 공정의 섭씨 100 내지 160도의 1 내지 3시간의 공정온도를 견디지 못하는 내열특성을 가지고 있는바, 제품의 생산에 있어서 휨, 비틀림, 변색, 수축 등의 다양한 불량요인으로 인해 제품양산이 불가능하다는 단점이 있고, 더 나아가 발광 다이오드 상에 전극을 적층하여 기판과 전극 사이에 발광 다이오드가 형성되어 있어 전극이 외부로 노출되어 외력에 취약하다는 구조적 불안정성을 가지면서도 이를 해결하기 위한 마땅한 수단을 제시하지 못하고 있는 상황이다.The transparent display device has an advantage that the user can see the subject on the back side of the display unit together with the content displayed on the display unit because the display unit is transparent. Conventional materials for transparent materials for displays such as LEDs have many disadvantages in that the material which absorbs the yellow wavelength band is large, but the particle size is large and the luminance deterioration largely occurs, and also it is difficult to maintain high-temperature reliability and color purity using organic pigments. Also, even when PC, PVC, or PET is used as the transparent substrate, such a film has heat resistance characteristics such that the heat resistance property can not withstand a process temperature of 1 to 3 hours of 100 to 160 degrees Celsius of the COB process, It is impossible to mass-produce a product due to various defects such as warpage, twist, discoloration, and shrinkage in production, and further, there is a problem that a light emitting diode is formed between the substrate and the electrode by stacking electrodes on the light emitting diode, And it is structurally unstable to be vulnerable to external forces, but does not provide a means to solve it.
본 발명의 목적은 노란색 빛을 차단하는 디스플레이용 투명부재를 제공하는 것을 목적으로 한다. It is an object of the present invention to provide a transparent member for a display which shields yellow light.

The transparent member may have a thickness within a range of 10 A to 10,000 A, and the transparent member may have a visible light transmittance of 50% or more.
상기 투명부재는 기재에 노란빛을 흡수하는 Nd계 화합물 층이 코팅된 것을 특징으로 한다. 상기 투명부재 내에는 Nd계 화합물이 10ppm 이상 함유된 것을 특징으로 한다.The transparent member is characterized in that the substrate is coated with a Nd-based compound layer that absorbs yellow light. Wherein the transparent member contains 10 ppm or more of an Nd based compound.
또한 상기 노란빛을 흡수하는 투명부재는 Nd(OCH3)3, Nd(OC2H5)3 등의 Nd의 유기금속화합물을 원료로 하여 코팅하여 건조하거나 CVD 법으로 만들어진 것을 특징으로 한다.In addition, a transparent member for absorbing the yellow light is characterized in that the Nd (OCH 3) 3, Nd (OC 2 H 5) drying the coating to the organometallic compounds, such as 3 or Nd into the raw material made by a CVD method.
상기 Nd2O3 층은 Nd2O3 Sol을 이용하여 만들어질 수 있고, Nd2O3 타겟을 이용하여 만들어질 수 있다.The Nd 2 O 3 layer can be made using Nd 2 O 3 Sol and can be made using an Nd 2 O 3 target.
한편, 상기 투명부재는 Neodium Metal 타겟을 이용하여 만들어질 수 있다.Meanwhile, the transparent member may be made of a Neodium Metal target.
그리고 상기 투명부재는 Nd2O3과 디스플레이용 광학부재를 컴파운드하여 만들어질 수도 있다. 이와 같은 디스플레이용 투명기재는 투명 플라스틱 필름, 시트, 유리, 석영(Quartz)으로부터 선택되는 것을 특징으로 한다.The transparent member may be made by compounding Nd 2 O 3 and an optical member for display. Such a transparent substrate for display is characterized by being selected from a transparent plastic film, a sheet, a glass, and a quartz.
본 발명의 목적은 Nd(OCH3)3, Nd(OC2H5)3 등의 Nd의 유기금속화합물을 원료로 하여 노란색 광만 선택적으로 흡수시키는 색재현성을 높인 투명 디스플레이용 부재를 제조할 수 있다. 따라서 이러한 투명 디스플레이용 부재를 사용하여 내열성, 신뢰성에서 차별화되는 투명 디스플레이 장치를 얻을 수 있다.An object of the present invention can be prepared for Nd (OCH 3) 3, a transparent display member for enhanced color reproducibility of yellow only light selectively absorbed by the organometallic compound of Nd, such as Nd (OC 2 H 5) 3 as a raw material .
