Abstract

The invention discloses a touch panel and a display device. According to the touch display product, the virtual electrodes insulated from the touch electrodes are arranged on the electrode layer, whenthe touch display product is used under the normal grounding condition, the touch area can be enlarged through the arrangement of the virtual electrodes, more sensing areas can sensitively sense thetouch behavior of a user, and therefore the touch sensitivity is improved; when the touch display product is used under the weak grounding condition (for example, a mobile phone is placed on a desktopor a user lies on a bed and the like); a virtual electrode is manufactured on an electrode layer; the virtual electrode is grounded through a virtual electrode lead; when the touch display product isused under the weak grounding condition, the touch display product is lightly grounded; according to the touch panel, the virtual electrodes are arranged between the touch electrodes, electric charges between the touch electrodes can be transmitted to the virtual electrodes through fingers, due to the fact that the virtual electrodes are grounded, the electric charges between the touch electrodescan be well transmitted to the ground, strong semaphore can also be detected for the touch electrodes, the situation of multi-point false alarm of an IC is avoided, and the use experience of a user is improved.

Description

technical field [0001] The present invention relates to the technical field of touch display, in particular to a touch panel and a display device. Background technique [0002] The touch panel is generally used in combination with the display panel. The existing mutual capacitive touch panel is provided with a plurality of touch driving electrodes Tx and a plurality of touch sensing electrodes Rx which are insulated and intersected. [0003] As a form of touch panel, the touch driving electrodes and the touch sensing electrodes can be grid-shaped electrodes arranged on the same layer and spaced from each other (one type of electrode can be bridged at the connection of the two electrodes), through the capacitance between adjacent sides Sensing realizes touch. Contents of the invention [0004] The embodiment of the present invention provides a touch panel and a display device, which are used to solve the problem of poor touch performance caused by multiple false alarms of ...
