Problems solved by technology

[0003] However, in the prior art, when the touch display panel is dug out to embed the grooved area of ​​functional modules such as cameras, part of the electrodes of the touch driving electrodes and touch sensing electrodes of the touch panel are usually missing. However, the resistance value of the touch driving electrode or touch sensing electrode missing part of the electrode will increase, while the capacitance value will decrease, which will lead to the weakening of the touch signal transmitted by the touch electrode and reduce the performance of the touch display panel. Touch Sensitivity

Abstract

The invention relates to a touch display panel and a touch display device. The touch display panel comprises a display area and a non-display area surrounding the display area. the non-display area comprises at least one grooving area arranged at any position around the display area; the display area comprises a first display area and a second display area, the second display area is located between the first display area and the grooving area, the first display area and the second display area comprise a plurality of induction electrodes arranged in the first direction and a plurality of driving electrodes arranged in the second direction, and the induction electrodes and the driving electrodes are arranged in a mutually crossed and insulated mode; Wherein the sensing electrode and / or thedriving electrode comprise / comprises a plurality of electrode units, and each electrode unit comprises an electrode pattern and at least one dummy pattern; And the virtual patterns of the electrode units in the second display area are electrically connected with the electrode patterns. According to the touch display panel, by increasing the area of the electrode pattern in the second display area, the touch sensitivity of the display area near the grooving area of the touch display panel is effectively improved.

Description

technical field [0001] The present invention relates to the field of touch display, in particular to a touch display panel and a touch display device. Background technique [0002] With the rapid development of display technology, touch display technology has gradually pervaded people's lives. Among the existing touch display panels, the capacitive touch display panel has the advantages of long life, high light transmittance, multi-touch support, etc., and has become a hot spot of touch display technology. In recent years, in order to meet the diverse needs of people, the existing touch display panels usually need to cut the edge, for example, dig a certain area of ​​slotting area on the upper edge of the touch display panel, and in the slotting area Embed functional modules such as cameras. [0003] However, in the prior art, when the touch display panel is dug out to embed the grooved area of ​​functional modules such as cameras, part of the electrodes of the touch drivi...
