Abstract: Disclosed are a panel capable of performing transparent display, a display device and a vehicle-mounted display device. A transmission part includes an organic light-emitting diode so as to perform light emission as well as display, thereby increasing an emission area, reducing the driving voltage required for emission driving, and consequently increasing the lifespan of the display device.

Abstract: An organic light emitting diode (OLED) and an organic light emitting device (e.g., a display device or a lighting device) thereof are described. The OLED comprises a first electrode, a second electrode, a first emitting part (including a first hole transporting layer (HTL) and a first emitting material layer (EML), positioned between the first and second electrodes); and a second emitting part (including a second EML and positioned between the first emitting part and the second electrode). The first EML is a blue EML, and the second EML includes at least one of a red EML and a blue EML. The first hole HTL includes a high refractive layer having a first refractive index, and a low refractive layer having a second refractive index, positioned between the high refractive layer and the first EML, where the second refractive index is smaller than the first refractive index.

Abstract: An organic light emitting diode (OLED) and an organic light emitting device (e.g., a display device or a lighting device) comprising the OLED are described. An emissive layer includes a red emitting material layer, a yellow-green emitting material layer and a green emitting material layer disposed sequentially between two electrodes, where each of the emitting material layers has controlled thickness and includes at least one host with controlled energy level. The OLED and the organic light emitting device have improved pure color luminous efficiency and color gamut, as well as luminous efficiency and luminous lifespan.

Abstract: An organic light-emitting device and an organic light-emitting display device using the same are discussed. In a structure in which emission layers that emit light having the same color are provided in a plurality of stacks, the emission layers have different properties such that the light emission efficiencies of the stacks are made uniform, whereby the lifespan of the organic light-emitting device is increased through charge balance.
