Patents by Inventor You-Hong Jhang

You-Hong Jhang 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: 10895943
    Abstract: The present invention provides a display module with touch function, including: a touch display panel and a control chip. The touch display panel contains a display area and non-display area around the display area. The display area contains a first sensing electrode constituted by a pixel electrode layer. The non-display area contains two second sensing electrodes. The control chip electrically connects with the first sensing electrode and the two second sensing electrodes separately through wires. The first sensing electrode and the second sensing electrode are self-capacitance sensing electrode. The control chip is used to read the self-capacitance variation of the first sensing electrode and the two second sensing electrodes for outputting a touch signal.

  • Patent number: 10838540
    Abstract: A touch control device with ESD protection includes a touch display panel, a switching unit, a touch electrode and a ground electrode. An ESD protection electrode is provided around at least one periphery of the touch display panel. A scanning period of the ESD protection electrode is divided into touch periods and ESD periods. When the scanning period of the ESD protection electrode is during the touch periods, the ESD protection electrode is used as touch electrodes for sensing touch events made by a user on the touch display panel. When the scanning period of the ESD protection electrode is during the ESD periods, the ESD protection electrode is used as ESD protection electrodes for dissipating ESD on the touch display panel in order to protect signal elements inside the touch display panel. The ESD protection electrode is therefore used for not only ESD protection, but also touch sensing.
