DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18605855 titled 'DISPLAY DEVICE
The patent application describes a display device that utilizes linearly polarized light, circularly polarized light, retardation films, holographic optical elements, reflective polarizers, and lens elements to enhance the display quality.
- The display module emits linearly polarized light.
- A holographic optical element reflects circularly polarized light at a specific angle and transmits light at different angles.
- Retardation films are used to manipulate the polarization of light.
- A reflective polarizer reflects linearly polarized light and transmits a different polarization.
- A lens element condenses circularly polarized light and converts it into a different polarization.
Potential Applications: - Enhanced display quality in electronic devices. - Improved visibility and clarity in screens. - Advanced optical technologies in various industries.
Problems Solved: - Enhancing the quality of displayed images. - Optimizing the use of polarized light for better visual effects.
Benefits: - Crisp and clear display output. - Reduction of glare and reflections. - Enhanced viewing experience for users.
Commercial Applications: Title: Advanced Display Enhancement Technology for Electronic Devices This technology can be utilized in smartphones, tablets, laptops, televisions, and other electronic devices to improve the quality of displayed images and enhance user experience.
Questions about the technology: 1. How does the holographic optical element contribute to the display quality? The holographic optical element reflects circularly polarized light at a specific angle, enhancing the overall brightness and clarity of the display.
2. What role do the retardation films play in manipulating light polarization? The retardation films are used to adjust the polarization of light, ensuring optimal display quality and reducing unwanted visual artifacts.
Original Abstract Submitted
According to one embodiment, a display device includes a display module configured to emit display light which is linearly polarized light, a first retardation film, a holographic optical element which is configured to reflect first circularly polarized light having a specific incident angle and transmit light having an incident angle which is different from the specific incident angle, a second retardation film, a reflective polarizer which is configured to reflect first linearly polarized light and transmit second linearly polarized light, a third retardation film, and a lens element which has a lens effect of condensing first circularly polarized light and converting first circularly polarized light into second circularly polarized light.
