It should be noted, figure 1 The array substrate in is only exemplary. In reality, the number of connection points corresponding to the second touch electrode block of the array substrate may be less than 10% of the number of connections corresponding to the first touch electrode block. In this case It can seriously affect the uniformity of the touch sensitivity of the curved touch display panel, that is, when the first touch electrode block and the second touch electrode block in the touch display panel sense an external touch, the second touch The touch sensing signal volume of the electrodes is much smaller than the touch signal volume of the first touch electrode side, which results in the touch sensitivity of the arc chamfer in the curved touch display panel being worse than that of other areas.

The invention discloses an array substrate and a touch display panel. The array substrate comprises a display region and a non-display region surrounding the display region. In one embodiment, the array substrate comprises a plurality of touch electrode blocks and a plurality of touch signal lines; the touch electrode blocks are composed of first touch electrode blocks and second touch electrode blocks; each first touch electrode block is only placed in the display region; each second touch electrode block is composed of a first part arranged in the display region and a second part arranged in the non-display region; each first touch electrode block is electrically connected with at least one touch signal line through m through holes; and each second touch electrode block is electrically connected with at least one touch signal line through n through holes, wherein m and n are positive integers and have the following relationship that m / n is larger than or equal to 1 and smaller than or equal to 5. According to the embodiment, the amount difference between through holes corresponding to the second touch electrode blocks and those corresponding to the first touch electrode blocks can be reduced, and the uniformity of the touch induction sensitivity of the touch display panel is improved.
Description
technical field [0001] The present application relates to the field of display technology, in particular to an array substrate and a touch display panel including the array substrate. 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 devices usually need to cut the edges to form a more ergonomic curved touch display panel, or form a special-shaped panel that can be installed with various functional modules such as cameras. Touch display panel. [0003] Existing curved touch display panels and the like usually include an array substrate, ...
