Abstract

The invention discloses a touch display panel and a display device, and belongs to the technical field of display, a display area of the touch display panel comprises a plurality of touch electrode blocks arranged in an array, and each touch electrode block is electrically connected with at least one touch signal line; a plurality of touch electrode blocks arranged in the first direction form a touch electrode row, and for the same touch electrode row, the distance between each touch electrode block and the first edge is gradually reduced and the distance between each touch electrode block andthe second edge is gradually increased along the third edge to point to the fourth edge; each touch signal line comprises a first sub-line and a second sub-line which are connected with each other, the first sub-line is located in the display area, and the second sub-line is located in the non-display area. The display device comprises the touch display panel. According to the invention, the areas of the touch electrode blocks tend to be consistent, the touch detection sensitivity and the overall uniformity of touch detection are improved, and the touch performance is improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a touch display panel and a display device. Background technique [0002] With the rapid development of display technology, touch screen panels (Touch Screen Panels) have gradually spread in people's lives. A touch display panel is a display device that has both display and command input functions. The user can directly touch the touch panel with a hand or an object, and the touch panel can detect the touch point and make a corresponding response according to the area touched by the user. Touch panels are used in personal mobile communication devices and comprehensive information terminals, such as tablet computers, smart phones, super notebook computers and other major human-computer interaction interfaces. [0003] Touch screens include external touch screens and built-in touch screens, among which the built-in touch screen is popular because of its thinness...
