LI8020SA CMOS Sensor | Proposals and Imaging Examples
Microdisplay is displayed as display-related devices in the AR/VR market, which is expected to expand in the future. Canon's ultra-multipixel sensor (250M) enables high-resolution microdisplay inspection.
High-quality inspection can be done with high-speed time for OLED/Micro LED.
Example of High-quality microdisplay defect inspection
Ultra-multipixel sensor (250M) and telecentric lens (2x)The LI8020 sensor can be used with a variety of lenses due to its APS-H sensor size.

Example of simultaneous inspection of microdisplay
To inspect several microdisplays simultaneously, the required sensor pixel allocation is as follows.
| Observe Number of microdisplay pixels |
Pixel allocation during inspection |
Number of simultaneous observations |
Number of sensor pixels required |
|---|---|---|---|
| FHD（1920×1080） | 3×3 | 4 | 75M |
| FHD（1920×1080） | 3×3 | 9 | 167M |
| FHD（1920×1080） | 3×3 | 12 | 223M |
| 4K2K（3840×2160） | 5×5 | 1 | 207M |
Up to 12 units can be inspected simultaneously, contributing to shorter takt time.
