Following specific embodiment will further illustrate the present invention with reference to above-mentioned accompanying drawing.
Specific embodiment
Below in conjunction with the accompanying drawings and better embodiment is described in further detail to the present invention：
Embedded touch control panel how is enable optionally to be re-used as simple display floater, so as to the driving chip for looking good with pure display function is the important research direction of the present invention；Certainly, the embedded touch control panel can also arrange in pairs or groups touch display function integrated touch control display driver chip (TDDI,
Touch with Display Drive Integration) realizing touch-control and display function.The specific embodiment that subsequent implementation mode solves the above problems there is provided the present invention.
Fig. 1 is refer to, the better embodiment of display device of the present invention 100 includes a touch-control display panel 10 and a driving chip 20.Wherein, the touch-control display panel 10 is used for display image and sensing touch control operation.In the present embodiment, the touch-control display panel 10 is an embedded touch display panels.
The touch-control display panel 10 includes that a touch-control circuit 12, for sensing touch control operation is used for the display circuit 14 and an on-off circuit 16 of display image.The touch-control circuit 12 includes touch-control sensing unit.The display circuit 14 includes the thin film transistor (TFT) array for driving display layer to show.The display layer can be a liquid crystal layer or a self luminous organic luminous layer, be not limited thereto.The unlatching that the on-off circuit connects the touch-control circuit 12 to control the touch-control circuit 12 is whether.The driving chip 20 connects the display circuit 14 of the touch-control display panel 10 to drive 10 display image of the touch-control display panel, the driving chip 20 also connects the touch-control circuit 12 by the on-off circuit 16, selectively to sense the touch control operation on the touch-control display panel 10.
Specifically, Fig. 2 is refer to, when the driving chip 20 is a touch-control display driver chip 22, the touch-control display driver chip 22 includes controlling switch C1 for showing pin D1, touch-control pin T1 and one first control signal of output.The display pin D1 of the touch-control display driver chip 22 connects the display circuit 14, to realize the display function of the touch-control display panel 10.Specifically, the display pin D1 connects the drives line of thin film transistor (TFT) array respectively.The touch-control pin T1 of the touch-control display driver chip 22 connects the touch-control circuit 12, to sense the touch control operation on the touch-control display panel 10.Controlling switch C1 of the touch-control display driver chip 22 connects the on-off circuit 16.During work, the first control signal that controlling switch C1 of the touch-control display driver chip 22 is exported gives the on-off circuit 16, and then the on-off circuit 16 opens the touch-control circuit 12, the touch-control circuit 12 receives the signal of the touch-control pin T1 from the touch-control display driver chip 22, to realize the touch controllable function on the touch-control display panel 10.Now, the touch-control display panel 10 can realize touch display function.
