OPTICAL FILTER AND DISPLAY DEVICE INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18495991 titled 'OPTICAL FILTER AND DISPLAY DEVICE INCLUDING THE SAME
Simplified Explanation
The optical filter described in the patent application includes a substrate with pixel areas and a light-blocking area, color filters, conversion layers with inclined side surfaces, and reflective layers on the conversion layers.
- The optical filter has a substrate with pixel areas and a light-blocking area in between.
- Color filters are arranged on the substrate corresponding to the pixel areas.
- Conversion layers with inclined side surfaces are also arranged on the substrate corresponding to the color filters.
- Reflective layers are present on the inclined side surfaces of the conversion layers, extending to the light-blocking area.
- Potential Applications:**
- Image sensors in digital cameras
- Display screens in electronic devices
- Optical systems in medical devices
- Problems Solved:**
- Improved color accuracy in imaging devices
- Reduction of light leakage in optical systems
- Enhanced contrast in display screens
- Benefits:**
- Enhanced image quality
- Reduced interference from ambient light
- Improved overall performance of optical devices
Original Abstract Submitted
An optical filter includes a substrate including a plurality of pixel areas spaced apart from each other and a light-blocking area between the plurality of pixel areas, a plurality of color filters arranged on a first surface of the substrate and corresponding to the plurality of pixel areas, and a plurality of conversion layers arranged on the first surface of the substrate and corresponding to the plurality of color filters. Each of the conversion layers includes inclined side surfaces. The optical filter further includes a reflective layer on the inclined side surfaces of each of the plurality of conversion layers. The reflective layer extends to the light-blocking area and is arranged consecutively on two adjacent inclined side surfaces from among the inclined side surfaces of the plurality of conversion layers and the light-blocking area between the two adjacent inclined side surfaces.
