Patent number: 11308725Abstract: A touch display device, including a protective layer, a display module, a touch layer, a fingerprint sensor layer, a backlight, and a shading layer. The fingerprint sensor layer and the touch layer are stacked together in the display area of the display device. By integrating the fingerprint sensor layer and the touch layer, the fingerprint recognition function can be realized while implementing the touch display, which not only reduces the production process, reduces the production cost, but also reduces the overall thickness of the display device.Type: GrantFiled: April 25, 2019Date of Patent: April 19, 2022Assignee: WUHAN CHINA STAR OPTOELECTRONICS TECHNOLOGY CO., LTD.Inventor: Huanhuan Bu

Patent number: 11288892Abstract: The present disclosure provides a display panel and a display device. The display panel includes a touch sensing module. The touch sensing module includes a touch control unit, a fingerprint sensing module, a vibrating acoustical unit, and a common electrode. The common electrode covers all the above-mentioned and time-divisionally transmits a touch control signal, a fingerprint sensing signal, and a vibrating acoustical signal. Therefore, sound on display functions and fingerprint recognition functions are achieved and holes on the front surface of the display panel are no longer required, which helps increase screen ratio.Type: GrantFiled: November 11, 2019Date of Patent: March 29, 2022Assignee: Wuhan China Star Optoelectronics Technology Co., Ltd.Inventor: Huanhuan Bu
