Self-capacitance touch structure having touch electrodes with side wing portions and display device thereof

A touch panel, comprising a self-capacitance touch structure, the self-capacitance touch structure comprising a plurality of self-capacitance touch electrodes arranged in an array, each self-capacitance touch electrode comprising a main body portion having a strip shape comprising two opposite long sides extending in a first direction, and a first side wing portion and a second side wing portion symmetrically disposed at the two opposite long sides of the main body portion of the main body portion, wherein

• for each self-capacitance touch electrode, a recess is formed between each side wing portion and the main body portion;
• the self-capacitance touch electrodes in a same row are spaced from each other, the self-capacitance touch electrodes in two adjacent rows are arranged in a staggered manner, the main body portion of at least one self-capacitance touch electrode in at least one row extends into a gap between two adjacent self-capacitance touch electrodes in another row;
• the first side wing portion of at least one self-capacitance touch electrode in at least one row extends into the recess between the second side wing portion and the main body portion of the self-capacitance touch electrode, adjacent to the at least one self-capacitance touch electrode, in another row;
• and
• the second side wing portion of at least one self-capacitance touch electrode in at least one row extends into the recess between the first side wing portion and the main body portion of the self-capacitance touch electrode, adjacent to the at least one self-capacitance touch electrode, in another row.

A display device, comprising a touch screen comprising a self-capacitance touch structure, the self-capacitance touch structure comprising a plurality of self-capacitance touch electrodes arranged in an array, each self-capacitance touch electrode comprising a main body portion having a strip shape comprising two opposite long sides extending in a first direction, and a first side wing portion and a second side wing portion symmetrically disposed at the two opposite long sides of the main body portion, wherein

• for each self-capacitance touch electrode, a recess is formed between each side wing portion and the main body portion;
• the self-capacitance touch electrodes in a same row are spaced from each other, the self-capacitance touch electrodes in two adjacent rows are arranged in a staggered manner, the main body portion of at least one self-capacitance touch electrode in at least one row extends into a gap between two adjacent self-capacitance touch electrodes in another row;
• the first side wing portion of at least one self-capacitance touch electrode in at least one row extends into the recess between the second side wing portion and the main body portion of the self-capacitance touch electrode, adjacent to the at least one self-capacitance touch electrode, in another row;
• and
• the second side wing portion of at least one self-capacitance touch electrode in at least one row extends into the recess between the first side wing portion and the main body portion of the self-capacitance touch electrode, adjacent to the at least one self-capacitance touch electrode, in another row.
