ORGANIC EL DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240324428 titled 'ORGANIC EL DISPLAY DEVICE
The abstract describes an organic EL display device that can prevent a change in tint when white display is viewed from an oblique angle. This device includes an organic EL display element and a light absorption anisotropic layer made of a composition containing a liquid crystal compound and a dichroic substance. The angle between the transmittance central axis of the layer and the normal line of the layer plane is between 0° and 450°, and the thickness of the layer is 15 to 225 nm at the maximal absorption wavelength.
- Light absorption anisotropic layer prevents tint change in white display viewed obliquely
- Contains liquid crystal compound and dichroic substance
- Specific angle and thickness of the layer ensure effectiveness
Potential Applications: - High-quality displays for electronic devices - Improved visibility and color accuracy in various lighting conditions
Problems Solved: - Maintains consistent tint in white displays viewed from different angles - Enhances overall display performance and user experience
Benefits: - Enhanced display quality and color accuracy - Improved viewing experience from different angles - Potential for energy efficiency in display technology
Commercial Applications: Title: Advanced Organic EL Display Devices for Enhanced Viewing Experience This technology can be used in smartphones, tablets, TVs, and other electronic devices to provide users with a superior viewing experience. The improved color accuracy and visibility can attract consumers looking for high-quality displays.
Questions about Organic EL Display Devices: 1. How does the light absorption anisotropic layer contribute to preventing tint changes in the display? The light absorption anisotropic layer, made of a composition containing a liquid crystal compound and a dichroic substance, helps maintain consistent tint by controlling light absorption at different angles.
2. What are the potential market implications of implementing this technology in electronic devices? Implementing this technology can lead to increased consumer interest in devices with superior display quality, potentially boosting sales and market competitiveness.
Original Abstract Submitted
an organic el display device capable of suppressing a change in tint in a case where white display is visually recognized from an oblique direction. the organic el display device includes an organic el display element and a light absorption anisotropic layer, in which the light absorption anisotropic layer is a light absorption anisotropic layer formed of a composition containing a liquid crystal compound and a dichroic substance, an angle between a transmittance central axis of the light absorption anisotropic layer and a normal line of a layer plane of the light absorption anisotropic layer is 0� or more and 450 or less, and a(�) of the light absorption anisotropic layer represented by expression (1) a(�)={kz(�)−(kx(�)+ky(�))/2}�d, is 15 to 225 nm at a maximal absorption wavelength of the light absorption anisotropic layer.
