Abstract
(EN)
A metal mesh touch-control electrode assembly, comprising: a metal mesh (5), multiple first electrode columns (1), and multiple second electrode rows (2), wherein the multiple first electrode columns (1) are disposed on the metal mesh (5), and each of the first electrode columns (1) comprises multiple first electrode units (10) connected to each other; each of the first electrode units (10) comprises a first outer frame pattern (100), multiple first connection portion patterns (101), and multiple first boundary portion patterns (102); the first connection portion patterns (101) comprise first T-shaped portions (1011) and first straight portions (1012); each of the second electrode rows (2) comprises multiple second electrode units (20) connected to each other; each of the second electrode units (20) comprises a second outer frame pattern (200), multiple second connection portion patterns (201), and multiple second boundary portion patterns (202); and each of the second connection portion patterns (201) comprises a second T-shaped portion (2011) and a second straight portion (2012). The first electrode units (10) and the second electrode units (20) have complicated geometric patterns, which can effectively prevent visibility problems, such as visually unexpected visible stripe effects.
