Optical Filters TRIZ Cases
- Integrated Photoelectric Pixel Structure to Reduce Image Sensor Cross-Talk
A layered photoelectric pixel combines color filtering and light detection to cut cross-talk, improve signal quality, and lower sensor cost.
- Hologram Optical Element for Multi-Focal Virtual Image Displays
Wavelength-selective hologram layers create virtual images at different focal lengths without moving the display panel, saving space and improving viewing stability.
- Optical Filter Layer Structure for Uniform Pinhole and Lens Shapes
A two-resin optical filter covers the light-blocking layer edge to reduce pinhole and lens shape variation and improve detection accuracy.
- Under-Display Fingerprint Sensing for Fake Print Detection
Wavelength-selective sensing through a display panel helps distinguish fake fingerprints from registered prints with higher authentication reliability.
- Color Filter Imaging Sensor With Illuminance-Adaptive Pixel Binning
Illuminance-based pixel binning boosts low-light sensitivity while preserving resolution through color-region sensor grouping and filter layout.
