112 figure is that Fig. 6 shows the figure of a touch control electrode 112 as the fenestral fabric of mesh using pixel electrode 111.
Specifically, touched because above-mentioned touch display panel provided in an embodiment of the present invention is made using the gap of pixel electrode
Control electrode is in order to reduce interfering between display and touching signals, in the specific implementation, it is necessary to using touch-control and display rank
The mode of section timesharing driving, also, display driver chip and touch detection chip can also be integrated into one in the specific implementation
Individual chip, further reduces production cost.Specifically, the driver' s timing figure driven using timesharing and the drive shown in Fig. 4 a and Fig. 4 b
The identical of timing diagram is moved, be will not be repeated here.
Or, above-mentioned touch display panel provided in an embodiment of the present invention can also be by each wire and the same layer of pixel electrode
Set.So in the preparation, the structure of pixel electrode layer can be changed and is formed in the original gap location of each pixel electrode
Wire, therefore, on the basis of existing array base palte preparation technology, it is not necessary to increase extra technique, save and be produced into
This, improves production efficiency.
Further, in above-mentioned touch display panel provided in an embodiment of the present invention, when pixel electrode and touch control electrode
When being set with layer, in order to it is further simplify preparation technology, wire can with gate line with layer set, it is same with data signal line
Layer sets or set with common electrode layer with layer, is not limited thereto.
Based on same inventive concept, the embodiment of the present invention additionally provides a kind of display device, as shown in fig. 7, comprises this hair
Any of the above-described kind of touch display panel 1000 that bright embodiment is provided；Also include a housing 2000.The display device can be：Hand
Mechanical, electrical sub- paper, tablet personal computer, television set, display, notebook computer, DPF, navigator etc. are any to have touch display
The product or part of function.The implementation of the display device may refer to the embodiment of above-mentioned touch display panel, repeat part not
Repeat again.
Touch-screen provided in an embodiment of the present invention, touch display panel and display device, due to being set in the top of wire
There is electro-magnetic screen layer, and projection of the wire on substrate is at least partially disposed in the range of electro-magnetic screen layer.Therefore the electromagnetism
Screen layer can shield the influence for the wire that body capacitance is pointed in the electro-magnetic screen layer location, be somebody's turn to do so as to eliminate and be located at
The noise produced by wire in the range of electro-magnetic screen layer, to reduce the noise on wire to the touch-control sensing in touch control electrode
The influence of signal, and then improve the signal to noise ratio of touch-screen touch-control performance.
Obviously, those skilled in the art can carry out the essence of various changes and modification without departing from the present invention to the present invention
God and scope.So, if these modifications and variations of the present invention belong to the scope of the claims in the present invention and its equivalent technologies
Within, then the present invention is also intended to comprising including these changes and modification.
