On Semiconductor introduces a 50 megapixel CCD image sensor for smartphone display inspection

     ON Semiconductor, which is driving energy efficient innovation, has introduced a new 50 megapixel (50 MP) resolution charge-coupled device (CCD) image sensor to enable more efficient inspection of smartphone displays. The KAI-50140 is the highest resolution Interline Transfer CCD image sensor on the market today, providing the critical imaging detail and high image uniformity required for smartphone display inspection, circuit board inspection and mechanical assembly inspection, as well as aerial reconnaissance.

     The KAI-50140 features a 2.18:1 aspect ratio that matches modern smartphone formats, reducing the number of image captures required to detect a full display. 4.5um Interline Transfer CCD pixels for the KAI-50140 provide high resolution and a true electronic (global) shutter while maintaining critical imaging performance. The new device supports frame rates up to 4 fps by using a flexible 1, 2 or 4 output readout architecture, and uses the same pin definition as the popular KAI-29050, KAI-29052 and KAI-43140 image sensors. This allows the KAI-50140 to be used in existing camera designs with only minor electrical changes, speeding time to market for new devices.

     Herb Erhardt, vice president and general manager of ON Semiconductor's Industrial Solutions Division, said: "The specifications and aspect ratios of smartphone displays continue to expand in both actual size and pixel density, prompting us to develop an image sensor specifically designed to detect these devices. The KAI-50140's unique combination of high resolution, unmatched image uniformity and 2.18:1 pixel arrangement enables higher quality and more efficient inspection of modern smartphone displays."
