Patent number: 11893182Abstract: An electronic device, and a method for performing fingerprint sensing control on a display panel are provided. A sensing region of the display panel is divided into a plurality of fingerprint zones. The electronic device determines at least one target fingerprint zone from the fingerprint zones according to a touch location, wherein the fingerprint zones are coupled to a plurality of scanning groups, each of the scanning groups comprises one or more scanning lines, the at least one target fingerprint zone is coupled to a first scanning group and a second scanning group other than the first scanning group among the plurality of scanning groups. The electronic device scans the first scanning group with a first speed, and scans the second scanning group with a second speed higher than the first speed or skips scanning the second scanning group.Type: GrantFiled: October 5, 2022Date of Patent: February 6, 2024Assignee: Novatek Microelectronics Corp.Inventors: Shih-Cheng Chen, Cho-Hsuan Jhang, Chih-Peng Hsia, Shiang-Fei Wang, Su-Wei Lien

Patent number: 11507225Abstract: An electronic device, a fingerprint sensing control method and a fingerprint scanning control method are provided. A sensing region of a display panel is divided into a plurality of fingerprint zones. The electronic device determines at least one target fingerprint zone from the fingerprint zones according to a touched area. The electronic device scans the at least one target fingerprint zone to control the at least one target fingerprint zone for performing fingerprint sensing. The electronic device performs an accelerated scanning operation. The accelerated scanning operation includes: setting a scanning speed corresponding to at least one target scanning group coupled to at least the touched area to a first speed; and setting a scanning speed corresponding to one or more scanning groups other than the at least one target scanning group to a second speed higher than the first speed.Type: GrantFiled: June 3, 2021Date of Patent: November 22, 2022Assignee: Novatek Microelectronics Corp.Inventors: Shih-Cheng Chen, Cho-Hsuan Jhang, Chih-Peng Hsia, Shiang-Fei Wang, Su-Wei Lien

Patent number: 11321958Abstract: An electronic device and a fingerprint sensing control method thereof are provided. The electronic device includes a touch control circuit and a fingerprint sensing control circuit. The touch control circuit is coupled to the display panel. The touch control circuit performs touch detection on the display panel to obtain a finger press area corresponding to the finger on the display panel. The fingerprint sensing control circuit is coupled to the touch control circuit to obtain a finger press area. The fingerprint sensing control circuit is coupled to the display panel to perform a fingerprint sensing control on a display panel. The fingerprint sensing control circuit scans the finger press area on the display panel in a first direction during a first period and scans the finger press area in a second direction different from the first direction during a second period after the first period.Type: GrantFiled: December 25, 2019Date of Patent: May 3, 2022Assignee: Novatek Microelectronics Corp.Inventors: Cho-Hsuan Jhang, Shih-Cheng Chen, Su-Wei Lien, Chih-Peng Hsia, Shiang-Fei Wang
