Problems solved by technology

When the touch display panel is dug out to embed gaps in functional modules such as cameras, it usually results in the loss of some electrodes of the touch driving electrodes and touch sensing electrodes.
Furthermore, if a part of the touch driving electrode or touch sensing electrode located in the gap near the middle part of the electrode is missing, the resistance value of the touch driving electrode or touch sensing electrode will usually increase.
The increase of the resistance value of the touch electrode will lead to the weakening of the touch signal of the touch electrode, thereby affecting the touch sensitivity of the touch display panel.

Abstract

The invention discloses a touch control display panel and a touch control display device. The touch control display panel comprises a first substrate; a plurality of touch control electrode strips disposed on the first substrate, wherein the plurality of first touch control electrode strips comprise a plurality of complete touch control electrode strips and at least one special-shaped touch control electrode strip, the area of each special-shaped touch control electrode strip is smaller than that of each complete touch control electrode strip, each special-shaped touch control electrode strip comprises an electrode portion and a metal wiring portion, and each metal wiring portion and the corresponding electrode portion of the same special-shaped touch control electrode strip are parallelly connected; and a plurality of first touch control signal lines, wherein each first touch control signal line is electrically connected with the corresponding first touch control electrode strip. According to the embodiment, through parallelly connecting the electrode portion and the metal wiring portion of each special-shaped touch control electrode strip, resistance of the special-shaped touch control electrode strip is reduced, signal strength of touch control signals of each special-shaped touch control electrode strip is enhanced, and touch control sensitivity of the touch control display panel is increased.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a touch display panel and a touch display device including the touch display panel. 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, compared with resistive touch display panels, capacitive touch display panels have the advantages of long life, high light transmittance, and support for multi-touch, and have become a hot spot in touch display technology. . Moreover, in order to meet the diverse needs of people, the existing touch display panel usually needs to cut the edge, and dig out a gap in the touch display panel that can be embedded with functional modules such as a camera. [0003] Existing touch display panels usually include touch driving electrodes and touch sensing electrodes intersecting. Mutual capacitance will be formed ...
