Patents by Inventor Sin-Cheng LIN

Sin-Cheng LIN has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10803278
    Abstract: Panel structure includes a substrate, a piezoelectric material layer and a thin film transistor. The piezoelectric material layer is disposed under the substrate, in which the piezoelectric material layer is configured to generate human recognizable sound waves by vibrating at a human audible frequency in a first time interval, and the piezoelectric material layer is configured to generate ultrasonic waves by vibrating at an ultrasonic frequency in a second time interval. The piezoelectric material layer is used for recognizing human fingerprints when it vibrates at the ultrasonic frequency. The thin film transistor is positioned under and electrically connected to the piezoelectric material layer.

  • Patent number: 10788912
    Abstract: A touch display module utilizing touch recognition by ultrasound includes display unit on substrate, barrier layer on other side of the substrate, and an ultrasound fingerprint sensing unit on the barrier layer. An acoustic impedance of the display unit, the barrier layer, and the ultrasonic fingerprint sensing unit are not all the same, and the differences in impedances enable recognition of touches by analysis of reflected ultrasound. The disclosure also provides an electronic device using the touch display module.
