Patent number: 12367821Abstract: This document describes systems and techniques directed at expediting fingerprint authentication via variable refresh rate control and display luminance compensation. In aspects, a computing device having an under-display fingerprint sensor (UDFPS) and a touch-sensitive display includes a biometric authentication manager. Upon detecting at least one finger at or near the touch-sensitive display, the biometric authentication manager implements variable display refresh rates and selectively adjusts luminance settings for a high-luminance region of the touch-sensitive display for predetermined intervals. In so doing, at least one finger can be well-illuminated during UDFPS image capturing, facilitating UDFPS sensing and expediting fingerprint authentication.Type: GrantFiled: October 25, 2023Date of Patent: July 22, 2025Assignee: Google LLCInventors: Jyothi Karri, Chien-Hui Wen

Publication number: 20250218415Abstract: This document describes a technology for reducing image ghosting on Always-On Display (AOD) panels when displaying high On-Pixel Ratio (OPR) images. The disclosed technology utilizes a multi-scan rate-capable AOD display panel to address the ghosting effect when the panel transitions from displaying a low OPR image to a high OPR image. To mitigate image ghosting and/or transitional flicker, the system briefly displays the high OPR image at a high scan rate before switching to a lower scan rate. This approach helps reduce ghosting and flicker helping to ensure power efficiency.Type: ApplicationFiled: February 21, 2025Publication date: July 3, 2025Applicant: Google LLCInventors: Hyunchul Kim, Chien-Hui Wen

Patent number: 12217722Abstract: Techniques and apparatuses are described that perform frequency compensation for a display. In aspects, a first uniformity of multiple regions of the display can be measured at a reference frequency. The display can then be driven at a second frequency and a second uniformity of the multiple regions of the display can be measured. The differences between the first and second uniformity can then be used to generate a compensation mask. XYZ domain data from the first and second uniformity measurements can be used to generate a color model characterization. The color model characterization can be used to convert the XYZ domain data into RGB data when the display is driven at the second frequency to compensate for the differences in uniformity across the multiple regions of the display.Type: GrantFiled: February 7, 2024Date of Patent: February 4, 2025Assignee: Google LLCInventors: Hyunchul Kim, Chien-Hui Wen, Ken Kok Foo
