DISPLAY APPARATUS HAVING A LIGHT-EMITTING DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240219606 titled 'DISPLAY APPARATUS HAVING A LIGHT-EMITTING DEVICE
Simplified Explanation: The patent application discusses a display apparatus with an encapsulation unit covering a light-emitting device and an optical unit that controls the viewing angle of the emitted light. The optical unit includes a linear polarizer, a dichroic dye layer, and an optical compensation layer to adjust the viewing angle.
- The display apparatus includes an encapsulation unit covering a light-emitting device.
- An optical unit is integrated into the encapsulation unit to control the viewing angle of the emitted light.
- The optical unit consists of a linear polarizer, a dichroic dye layer, and an optical compensation layer.
- The optical compensation layer helps compensate for the viewing angle of the dichroic dye layer by adjusting the in-plane and thickness direction phase retardation values.
- Different types of optical compensation layers can be used based on the specific requirements of the display apparatus.
Potential Applications: 1. Consumer electronics such as smartphones, tablets, and laptops. 2. Automotive displays for navigation systems and entertainment consoles. 3. Public displays in airports, train stations, and shopping malls. 4. Medical devices with display screens for monitoring and diagnostics.
Problems Solved: 1. Improved control over the viewing angle of emitted light. 2. Enhanced display quality and visibility in various lighting conditions. 3. Reduction of glare and reflections on the screen. 4. Better user experience with clear and sharp images from different angles.
Benefits: 1. Enhanced display performance with optimized viewing angles. 2. Reduced eye strain for users viewing the display. 3. Improved visibility in bright or dim environments. 4. Enhanced color accuracy and image quality. 5. Increased durability and longevity of the display apparatus.
Commercial Applications: The technology can be applied in various commercial sectors such as consumer electronics, automotive industry, public displays, and medical devices. It offers improved display performance, better user experience, and enhanced visibility, making it a valuable addition to products requiring high-quality display screens.
Questions about Display Apparatus: 1. How does the optical compensation layer contribute to adjusting the viewing angle in the display apparatus? 2. What are the potential market implications of integrating this technology into consumer electronics and other commercial products?
Original Abstract Submitted
discussed is a display apparatus that can include an encapsulation unit covering a light-emitting device and an optical unit on the encapsulation unit. the optical unit can control viewing angle of the light emitted from the light-emitting device. for example, the optical unit can include a linear polarizer, a dichroic dye layer disposed on the linear polarizer and an optical compensation layer disposed between the linear polarizer and the dichroic dye layer. thus, in the display apparatus, the viewing angle of the dichroic dye layer can be compensated by an in-plane phase retardation value (rin) and/or a thickness direction phase retardation value (rth) according to a type of the optical compensation layer.
