Research output: Patent / Technischer StandardPatent


The present invention relates to a multi-touch display system that supports both multi-touch human input as well as input from a digital pen. The display system has a display panel that is configured to allow human touches along a front surface to be detected and tracked. The display panel also includes a location pattern that preferably covers the viewable areas of the display panel. The location pattern is configured to allow any location within the location pattern to be detected by analyzing a portion of the display pattern that is associated with the particular location. The digital pen is used to "write" on the display panel, wherein such a writing function involves detecting the location where writing occurs and controlling display content that is displayed on the display panel to reflect what is being written.
