![Proposal of ultra-multi-pixel sensor(250M) for inspection of OLED and micro LED.](/-/media/Project/Canon/CanonJP/Website/business/solution/indtech/cmos/shared/image/keyvisual/en-750x370-OLED-insection.png?la=ja-JP&hash=55988040C40876C5468DA9C7F0C77116)
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 |
