Problems solved by technology

However, since the surface resistance value of the indium tin oxide material is very large, forming the touch sensing electrode 1' and the touch driving electrode 2' from the indium tin oxide material will cause an excessive load, thereby generating a large power consumption

Abstract

Embodiments of the present invention provide a touch display panel and a touch display device, which relate to the field of display technology and are used to reduce power consumption generated during touch control. The touch display panel includes a plurality of transparent touch electrodes and a plurality of metal touch electrodes, wherein the transparent touch electrodes are arranged along the first direction and extend along the second direction; the metal touch electrodes are arranged along the second direction and extend along the first direction. The transparent touch electrode includes a plurality of transparent electrode blocks arranged along the second direction, and two adjacent transparent electrode blocks are connected; the metal touch electrode includes a plurality of metal electrode blocks arranged along the first direction, adjacent to each other. Two metal electrode blocks are connected. The above-mentioned touch display panel is used to realize the touch function.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a touch display panel and a touch display device. 【Background technique】 [0002] With the development of display technologies, touch display panels with touch functions have been widely used. Such as figure 1 As shown, a plurality of touch sensing electrodes 1 ′ arranged in the column direction and a plurality of touch driving electrodes 2 ′ arranged in the row direction are arranged in the touch region of the touch display panel. When a finger touches the display screen, the mutual capacitance between the touch sensing electrode 1 ′ and the touch driving electrode 2 ′ at the touch position will change, thereby determining the touch position. [0003] In the prior art, the touch sensing electrodes 1 ′ and the touch driving electrodes 2 ′ are generally made of indium tin oxide material. However, since the surface resistance value of the indium tin oxide material is ...
