Problems solved by technology

[0004] However, since the transparent display area also has a display function, pixels and metal traces are arranged in the transparent display area, so when taking a picture, when the external light passes through the transparent display area, it is easy to diffract in the gap between the metal traces, thereby affecting Camera photo effect

Abstract

The invention discloses a touch display panel and a display device. The orthographic projection of a first touch electrode block on a display substrate at least covers gaps of signal lines between adjacent pixels. The first touch electrode blocks can be used for shielding light rays emitted to the gaps of the signal wires between the adjacent pixels in the first display area, and therefore opticaldiffraction cannot happen to the gaps of the signal wires shielded by the first touch electrode blocks. Moreover, the gaps of the signal lines between the adjacent pixels in the first display area are covered by the first touch electrodes, so that compared with a light blocking strip which is independently manufactured and used for blocking the gaps of the signal lines, process steps do not needto be increased, and the thickness of the touch display panel does not need to be increased.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a touch display panel and a display device. Background technique [0002] Mobile terminals such as mobile phones usually have a display panel and a camera. With the advancement of technology, the screen-to-body ratio of mobile terminals (the ratio of the area of ​​the display area of ​​the display panel to the area of ​​the front of the mobile terminal) continues to increase, and the screen is displayed toward the full screen. direction of development. [0003] In order to realize full-screen display, the display panel has a transparent display area and a non-transparent display area, wherein both the transparent display area and the non-transparent display area can display images, but the distribution density of pixels in the transparent display area is smaller than the distribution density of pixels in the non-transparent display area , the camera of the mobile terminal is se...
