Intelligent sensing touch display device
An intelligent sensing touch display device capable of being responsive to an application program to selectively perform a touch detection procedure on a first electrode group and/or on an active array unit, where a controller has a memory for storing background image data, and data of at least one object image, and is used for performing a local operation procedure including steps of: receiving location information of at least one touched GUI object provided by a touch and display driving unit and transmitting the location information to a main processing unit; receiving updated image data for at least one GUI object image from the main processing unit; combining the updated image data with the background image data to form locally updated display image data and transmitting the locally updated display image data to the touch and display driving unit.
1. An intelligent sensing touch display device, comprising:
a first electrode group having N first electrodes on a first plane, N being a positive integer;
an interface layer, which is a display material layer or a display and touch sensing material layer, located below the first electrode group for providing a display area on the display material layer, or providing a display area and at least one touch sensing area on the display and touch sensing material layer;
an active array unit having N second electrode units on a second plane located below the display material layer, each of the second electrode units having M second electrodes, each of the M second electrodes being controlled by at least one active switch and opposite to one said first electrode, M being a positive integer greater than 1, wherein when the interface layer is the display material layer, each of the second electrodes is used as a display electrode or a touch sensing electrode, and when the interface layer is the display and sensing material layer, a part of the second electrodes are used as display electrodes or touch sensing electrodes, and another part of the second electrodes are used as the touch sensing electrodes, the touch sensing electrode being a capacitive electrode, a photosensitive electrode, or a thermal sensing electrode; and
a touch and display driving unit coupled with the first electrode group and the active array unit for generating voltage signals or current signals to drive the interface layer to provide a display image, and/or for being responsive to an application program to selectively perform a first touch detection procedure on the first electrode group, or performing a second touch detection procedure on the active array unit, or performing the first touch detection procedure on the first electrode group, and then performing the second touch detection procedure on at least one area of the active array unit, wherein the at least one area is determined according to a detection result of the first touch detection procedure;
wherein one said first electrode and the M second electrodes form an AC channel touch sensing unit, so that the touch and display driving unit will recognize that the AC path touch sensing unit is touched when any electrode in the AC channel touch sensing unit is touched by a finger; and wherein a controller is coupled between the touch and display driving unit and a main processing unit, the controller has a memory for storing background image data, and data of at least one object image selected from a group consisting of at least one touched GUI object image and at least one GUI object image, and is used for performing a local operation procedure, the local operation procedure including steps of: receiving location information of at least one touched GUI object provided by the touch and display driving unit and transmitting the location information to the main processing unit; receiving updated image data for the at least one object image from the main processing unit; storing the updated image data in the memory; combining the updated image data with the background image data to form locally updated display image data; and transmitting the locally updated display image data to the touch and display driving unit.
