Patents by Inventor Yi-Han TU

Yi-Han TU 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: 11056078
    Abstract: A multi-screen color correction method and an electronic device are provided. The multi-screen color correction method is adapted with an electronic device with at least two display panels, and includes the following steps: obtaining image characteristics of test images displayed on the display panels respectively; performing a parameter operation on the image characteristics separately to obtain image correction parameters correspondingly; correcting colors of the display panels respectively according to the image correction parameters; obtaining luminance characteristics of the display panels by calculating based on the image correction parameters; and adjusting the luminance of the display panels according to the luminance characteristics.
