LIGHT EMITTING DEVICE, DISPLAY DEVICE, IMAGE SENSING DEVICE, AND ELECTRONIC APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18063099 titled 'LIGHT EMITTING DEVICE, DISPLAY DEVICE, IMAGE SENSING DEVICE, AND ELECTRONIC APPARATUS
Simplified Explanation
The patent application describes a light emitting device that includes a reflective film, electrodes, an organic film, and an optical member arranged on a substrate. The device also includes a bank that covers the peripheral portion of the first electrode to define a light emitting region. The reflective film, electrodes, and organic film form a resonator structure that resonates light generated in the organic film.
- The device includes a reflective film, electrodes, an organic film, and an optical member.
- A bank is used to cover the peripheral portion of the first electrode to define a light emitting region.
- The reflective film, electrodes, and organic film form a resonator structure that resonates light generated in the organic film.
- The upper surface of the reflective film in the light emitting region is flatter than the first electrode.
- The resonator structure has multiple optical path lengths.
Potential applications of this technology:
- Lighting: The light emitting device can be used for general lighting purposes, providing efficient and high-quality illumination.
- Displays: The device can be used in displays, such as televisions, smartphones, and monitors, to produce vibrant and high-resolution images.
- Signage: The technology can be applied in signage applications, creating eye-catching and energy-efficient signs.
Problems solved by this technology:
- Improved light emission: The resonator structure enhances the efficiency of light emission from the organic film, resulting in brighter and more vibrant light output.
- Flatter surface: The flatter upper surface of the reflective film in the light emitting region helps to reduce distortions and improve the overall quality of the emitted light.
- Multiple optical path lengths: The use of multiple optical path lengths in the resonator structure allows for better control and manipulation of the emitted light, leading to improved performance and versatility.
Benefits of this technology:
- Enhanced efficiency: The resonator structure improves the efficiency of light emission, resulting in energy savings and longer lifespan of the device.
- High-quality output: The technology produces high-quality light output with improved color accuracy and brightness.
- Versatility: The use of multiple optical path lengths in the resonator structure allows for flexibility in designing and controlling the emitted light, making it suitable for various applications.
Original Abstract Submitted
A light emitting device in which a reflective film, a first electrode, an organic film including a light emitting layer, a second electrode, and an optical member are arranged in this order on a principal surface of a substrate and a bank configured to cover a peripheral portion of the first electrode is provided to define a light emitting region. The reflective film, the first electrode, the organic film, and the second electrode form a resonator structure configured to resonate, between the reflective film and the second electrode, light generated in the organic film. In the light emitting region, an upper surface of the reflective film is flatter than the first electrode. The resonator structure has a plurality of different optical path lengths.
