AI Technical Summary
Technical Problem
Display devices, such as LCDs and OLEDs, experience light leakage from both front and side surfaces due to differences in polarization characteristics, which affects image quality and visibility.
Method used
A display device configuration that includes a display panel and an optical member with a specific layer structure, comprising a polarization layer and compensation layers (positive C and A plates) strategically positioned to manage phase delays and polarization states, thereby preventing light leakage from both front and side surfaces.
Benefits of technology
The proposed configuration effectively reduces light leakage from all surfaces, enhancing image quality and visibility by ensuring that only intended light is transmitted, while external reflections are minimized.
