For example, the light transmitting layer 140 may be formed on both the top and bottom surfaces of the second electrode 120, or may be formed on only one of the bottom and top surfaces of the second electrode 120.
이하, 본 실시예에서는 투광층(140)이 제2전극(120)을 사이에 두고 상면과 하면에 모두 형성되는 구성을 예시하였으나, 이에 한정되지 않고 제2전극(120)의 하면 및 상면 중 어느 하나에만 형성되는 구성도 동일하게 적용될 수 있음은 물론이다.Hereinafter, in the present exemplary embodiment, a configuration in which the light transmitting layer 140 is formed on both the upper and lower surfaces with the second electrode 120 interposed therebetween is not limited thereto.

여기서, 투광층(140)은 제2전극(120)이 투과성을 가지는 동시에 높은 투과율을 가질 수 있도록 기능을 한다. 그리고, 투광층(140)은 박막으로 형성되어 제2전극(120)의 면저항을 감소함으로써, TOLED 패널(20)의 성능 저하를 저지한다. 이러한 투광층(140)의 특성에 대해서는 후술할 산화물 계열, 질화물 계열, 염류 및 이들의 복합물을 설명한 후, 도 7 내지 도 9를 참조하여 상세히 설명하기로 한다.Here, the light transmitting layer 140 functions to allow the second electrode 120 to have a high transmittance while having a transmittance. In addition, the light transmitting layer 140 is formed of a thin film to reduce the sheet resistance of the second electrode 120, thereby preventing the performance degradation of the TOLED panel 20. The characteristics of the light-transmitting layer 140 will be described in detail with reference to FIGS. 7 to 9 after describing oxide-based, nitride-based, salts, and composites thereof to be described later.

상기와 같이 투광층(140)을 구성하는 산화물 계열, 질화물 계열, 염류 및 이들의 복합물을 사용하게 되면, 도 7 내지 도 9에 도시된 바와 같이 우수한 투과율과 휘도 효과를 나타내므로 바람직하지만, 상기와 같은 물질들 이외에도 제2전극(120)이 투과성을 가지는 동시에 높은 투과율을 가질 수 있도록 하는 물질은 모두 포함할 수 있다.When using the oxide-based, nitride-based, salts, and composites of the light-transmitting layer 140 as described above, as shown in Figs. 7 to 9 shows excellent transmittance and luminance effect, but as described above In addition to the same materials, the materials for allowing the second electrode 120 to have a high transmittance while having a permeability can be included.
투광층(140)은 제1투광층(141)과 제2투광층(142)이 동일한 물질로 구성되지만, 서로 상이한 물질로 구성될 수도 있다. 예를 들어, 제1투광층(141)은 산화물 계열을 포함하고 제2투광층(142)은 질화물 계열, 염류 및 이들의 복합물을 포함할 수 있다. 또는 제1투광층(141)은 질화물 계열을 포함하고 제2투광층(142)은 산화물 계열, 염류 및 이들의 복합물을 포함할 수 있다. 또는 제1투광층(141)은 염류를 포함하고 제2투광층(142)은 산화물 계열, 질화물 계열 및 이들의 복합물을 포함할 수 있다.The light transmitting layer 140 may be made of the same material as the first light transmitting layer 141 and the second light transmitting layer 142, but may be made of different materials. For example, the first light transmitting layer 141 may include an oxide-based, and the second light transmitting layer 142 may include a nitride-based, a salt, and a combination thereof. Alternatively, the first light transmission layer 141 may include a nitride series, and the second light transmission layer 142 may include an oxide series, salts, or a combination thereof. Alternatively, the first light transmission layer 141 may include salts, and the second light transmission layer 142 may include an oxide-based, nitride-based, and composites thereof.
투광층(140)의 두께는 0.1nm 이상 100nm 미만으로 형성되는 것이 바람직하다. 이러한 투광층(140)의 두께 수치 한정 이유를 예를 들어 설명하면, 투광층(140)의 두께가 0.1nm 미만으로 작아질 경우 투과율은 증가하나, 이에 비례하여 저항도 증가하므로 TOLED 패널(20)의 성능이 저하된다.The thickness of the light transmitting layer 140 is preferably formed in less than 0.1nm 100nm. For example, the reason for limiting the thickness value of the light-transmitting layer 140 will be described. If the thickness of the light-transmitting layer 140 is less than 0.1 nm, the transmittance increases, but the resistance also increases in proportion to the TOLED panel 20. Degrades performance.
반면, 투광층(140)의 두께가 100nm 이상으로 커질 경우에는 저항이 감소하여 성능 저하는 발생하지 않으나, 투광층(140) 두께의 증가에 따라 투과율이 감소한다. 그리고, 본 발명의 실시 예에 따른 투광층(140)은 열 증착법에 의해 형성되는 것이 바람직하다.On the other hand, when the thickness of the light transmitting layer 140 becomes larger than 100 nm, the resistance decreases and the performance does not occur, but the transmittance decreases as the thickness of the light transmitting layer 140 increases. In addition, the light transmitting layer 140 according to the embodiment of the present invention is preferably formed by thermal evaporation.
다음으로 도 7 내지 도 9에 도시된 바와 같이, 이러한 구성에 대해 본 발명에 따른 전자시계의 TOLED 패널(11)의 특성을 이하에서 살펴보면 다음과 같다.Next, as shown in FIGS. 7 to 9, the characteristics of the TOLED panel 11 of the electronic clock according to the present invention will be described below.
도 7은 본 발명의 TOLED 패널(11)에 형성된 투광층(140) 유무에 따른 투과율 그래프이다. 여기서, 도 7의 'a'는 투광층(140)을 형성한 본 발명에 따른 TOLED 패널(11)의 선도이고, 'b'는 본 발명과 달리 투광층(140)이 없는 TOLED 패널(11)의 선도이다.7 is a graph illustrating transmittance according to the presence or absence of a light transmitting layer 140 formed on the TOLED panel 11 of the present invention. Here, 'a' in FIG. 7 is a diagram of the TOLED panel 11 according to the present invention in which the light transmitting layer 140 is formed, and 'b' is a TOLED panel 11 without the light transmitting layer 140 unlike the present invention. Is leading.
본 발명에 따른 TOLED 패널(11)은 파장(nm)에 따라 70~99%의 투과율을 나타낼 수 있다. 예를 들어, 도 7에 도시된 바와 같이, 파장(nm)에 따른 투과율을 살펴보면, 550nm에서 본 발명에 따른 TOLED 패널(11)의 투과율은 약 80%를 나타내고, 투광층(140)이 없는 TOLED 패널(11)는 약 47%를 나타내고 있다. 이러한 결과에 대해 투광층(140)이 있는 TOLED 패널(11)의 투과율은 투광층(140)이 없는 TOLED 패널(11)에 대비 1.7배가 더 높음을 알 수 있다.The TOLED panel 11 according to the present invention may exhibit a transmittance of 70 to 99% according to the wavelength (nm). For example, as shown in FIG. 7, when looking at the transmittance according to the wavelength (nm), at 550 nm, the transmittance of the TOLED panel 11 according to the present invention is about 80%, and the TOLED without the light transmitting layer 140 is present. Panel 11 shows about 47%. For this result, it can be seen that the transmittance of the TOLED panel 11 with the light transmitting layer 140 is 1.7 times higher than that of the TOLED panel 11 without the light transmitting layer 140.
그리고, 도 8은 투광층(140) 유무에 따른 TOLED 패널(11)의 휘도 그래프이다. 도 8에 도시된 'c'는 본 발명에 따른 TOLED 패널(11)의 선도이고, 'd'는 투광층(140)이 없는 TOLED 패널(11)의 선도이다.8 is a luminance graph of the TOLED panel 11 with or without the light transmitting layer 140. 'C' shown in FIG. 8 is a diagram of the TOLED panel 11 according to the present invention, and 'd' is a diagram of the TOLED panel 11 without the light transmitting layer 140.
전압(V) 10V에 따른 휘도를 살펴보면, 투광층(140)이 있는 TOLED 패널(11)은 약 25000을 나타내고, 투광층(140)이 없는 TOLED 패널(11)은 약 20000을 나타내고 있다. 투광층(140)의 유무에 따라 휘도는 1.25배가 차이 남을 알 수 있다.Looking at the luminance according to the voltage (V) 10V, the TOLED panel 11 with the light-transmitting layer 140 is about 25000, the TOLED panel 11 without the light-transmitting layer 140 is about 20000. It can be seen that the luminance remains 1.25 times different depending on the presence or absence of the light transmitting layer 140.
