    Abstract: The present disclosure relates to an electronic device, such as a system on chip, that may perform firmware updates based on user consent. The system on chip includes a nonvolatile memory (NVM), a main processor, a security NVM, and a security processor. The nonvolatile memory (NVM) stores first firmware and a user permission indicator. The main processor Loads the first firmware to boot a security processor. The security NVM contains first version information. The security processor compares version information of the first firmware to the first version information based on the user permission indicator and executes the first firmware in response to the matching of the comparison result. In some examples, the security processor is implemented on the same chip as the main processor.

    Abstract: A display device is provided. The display device includes a display panel including a pixels; a fingerprint recognition sensor including an image sensor disposed under a first surface of the display panel; and a processor to control the display panel and the fingerprint recognition sensor. A portion of display pixels are configured to emit light in a fingerprint recognition mode. The image sensor includes pixels, at least a portion of the pixels are phase detection pixels. The image sensor generates a fingerprint image signal and a fingerprint phase signal based on reflected light received while the portion of display pixels emit light. The main processor is further configured to perform an anti-spoofing operation or a fingerprint authentication operation based on the fingerprint image signal and the fingerprint phase signal.
