Abstract

In an array substrate, a self-capacitive touch display panel, and an electronic apparatus of the present disclosure, the array substrate includes a touch control region, a plurality of interval rows, and a plurality of touch control connection lines. The touch control region includes an M number of touch control rows and a plurality of touch control columns. The interval rows are defined by adjacent touch control rows. The interval rows include a middle interval row at a middle position of the touch control region. Each of the touch control connection lines connects with two touch control units. The touch control columns include a first touch control column and a second touch control column that are adjacent to each other. Two touch control units disposed in the first touch control column and connected with a same touch control connection lines are symmetrically arranged relative to the middle interval row.
