技术领域technical field
本公开的实施例的一个或更多个方面涉及一种有机发光器件。One or more aspects of the embodiments of the present disclosure relate to an organic light emitting device.
背景技术Background technique
有机发光器件是具有宽视角、高对比度、短响应时间以及优异的亮度、驱动电压和响应速度特性的自发射器件，并可以产生全色图像。An organic light emitting device is a self-emitting device having a wide viewing angle, high contrast ratio, short response time, and excellent brightness, driving voltage, and response speed characteristics, and can produce full-color images.
有机发光器件可以包括设置在(例如，位于)基底上的第一电极以及顺序地设置在第一电极上的空穴传输区域、发射层、电子传输区域和第二电极。从例如第一电极提供的空穴可以经过空穴传输区域向发射层移动，从例如第二电极提供的电子可以经过电子传输区域向发射层移动。然后，诸如空穴和电子的载流子可以在发射层中复合以产生激子。这些激子从激发态跃迁到基态，从而产生光。An organic light emitting device may include a first electrode disposed on (eg, located on) a substrate, and a hole transport region, an emission layer, an electron transport region, and a second electrode sequentially disposed on the first electrode. Holes supplied from, for example, the first electrode may move to the emission layer through the hole transport region, and electrons supplied from, for example, the second electrode may move to the emission layer through the electron transport region. Carriers such as holes and electrons can then recombine in the emissive layer to generate excitons. These excitons transition from an excited state to a ground state, thereby generating light.

由于由从式1-1和式1-2中选择的一个表示的第一化合物和由从式2-1至式2-3中选择的一个表示的第二化合物具有快速电子传输特性和相对高的三重态能级，因此能量可以有效地传输到包括在发射层中的掺杂剂。另外，由从式1-1和式1-2中选择的一个表示的第一化合物可以用作适用于磷光发射的主体(例如，根据给出的实施例的第一化合物可以具有比相关技术中的可比较的磷光掺杂剂的三重态能级更高的三重态能级)。因此，包括以上描述的第一化合物的有机发光器件可以在发射层中有效地(或者适当地)产生激子并可以具有高效率。Since the first compound represented by one selected from Formula 1-1 and Formula 1-2 and the second compound represented by one selected from Formula 2-1 to Formula 2-3 have fast electron transport properties and relatively high triplet energy level, so energy can be efficiently transferred to the dopant included in the emission layer. In addition, the first compound represented by one selected from Formula 1-1 and Formula 1-2 can be used as a host suitable for phosphorescent emission (for example, the first compound according to the given examples can have higher triplet energy levels of comparable phosphorescent dopants). Accordingly, the organic light emitting device including the first compound described above may efficiently (or properly) generate excitons in the emission layer and may have high efficiency.
然而，即使在发射层中包括由从式1-1和式1-2中选择的一个表示的第一化合物的有机发光器件中，电子也会从发射层泄漏到空穴传输区域，因此，由于电流和电压的增大，导致效率显著降低。因此，有机发光器件可能需要进一步包括合适的空穴传输区域。However, even in the organic light emitting device including the first compound represented by one selected from Formula 1-1 and Formula 1-2 in the emission layer, electrons leak from the emission layer to the hole transport region, and therefore, due to The increase in current and voltage leads to a significant decrease in efficiency. Therefore, an organic light emitting device may need to further include a suitable hole transport region.
根据本公开的实施例，当由从式2-1至式2-3中选择的一个表示的第二化合物被包括在空穴传输区域中时，能够最小化或减少从发射层到空穴传输区域的电子泄漏。因此，发射层中产生的更多的激子可以对光发射作出贡献，并且可以改善有机发光器件的效率。另外，可以减少由于电子泄漏而导致的有机层的材料的劣化，可以减小呈现相同亮度(与劣化之前的亮度相同)所需要的电流的量，从而延长有机发光器件的寿命。According to an embodiment of the present disclosure, when the second compound represented by one selected from Formula 2-1 to Formula 2-3 is included in the hole transport region, it is possible to minimize or reduce the hole transport from the emission layer to the region of electron leakage. Therefore, more excitons generated in the emission layer can contribute to light emission, and the efficiency of the organic light emitting device can be improved. In addition, degradation of the material of the organic layer due to electron leakage can be reduced, the amount of current required to exhibit the same luminance (same as that before degradation) can be reduced, thereby prolonging the lifetime of the organic light emitting device.
