Integrated touch display panel and touch display device

Abstract

The invention provides an integrated touch display panel. The integrated touch display panel is characterized by comprising a substrate, a plurality of data lines and a plurality of strip-shaped touch electrodes. The plurality of data lines are set on the substrate and provide display signals for display pixels, the plurality of data lines are arranged orderly along a first direction and extend along a second direction, and the first direction intersects the second direction; the plurality of touch electrodes are arranged orderly along the first direction and extend along the second direction; in a direction perpendicular to the substrate, at least one of the touch electrodes is superposed with N data lines, and N is a natural number; and in a touch stage, the number of the data lines, of which display driving voltage is of positive polarity, of the N data lines is equal to that of the data lines of which the display driving voltage is of negative polarity. The integrated touch display panel provided by the embodiment of the invention can effectively reduce touch noise and improve touch precision.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel integrated with a built-in touch structure. Background technique [0002] With the development of modern electronic technology, corresponding structures are provided in the display panel of the display device to realize corresponding functions, for example, touch functions are realized by setting touch structures, so as to bring convenience to users. [0003] At present, in order to reduce the thickness of the display panel and realize the touch function, the touch structure is usually integrated in the display panel. When using the capacitive touch structure, the touch electrodes in the capacitive touch structure can be directly connected to the display panel. The structure is fabricated on the same substrate. The problem caused by this arrangement is that complex and constantly changing electrical signals will be input into the display structure and the touch s...

Problems solved by technology

[0003] At present, in order to reduce the thickness of the display panel and realize the touch function, the touch structure is usually integrated in the display panel. When using the capacitive touch structure, the touch electrodes in the capacitive touch structure can be directly connected to the display panel. The structure is fabricated on the same substrate. The problem caused by this arrangement is that complex and constantly changing electrical signals will be input into the display structure and the touch structure during the operation of the display panel, and these electrical signals will affect each other. Affect the touch performance or display performance of the display panel with integrated touch structure
