Abstract

The invention discloses a touch panel and a repair method thereof. The touch panel comprises a substrate, a plurality of first sensing universal serial buses, a plurality of second sensing universal serial buses and a plurality of conductive repair pattern layers, wherein the first sensing universal serial buses are configured on the substrate, extend in the first direction, and comprise a plurality of first sensing pads and a plurality of first bridging lines; each first bridging line is used for connecting every two adjacent first sensing pads in series; the second sensing universal serial buses are configured on the substrate, extend in the second direction, and comprise a plurality of second sensing pads and a plurality of second bridging lines; each second bridging line is used for connecting every two adjacent second sensing pads in series; the first direction is different from the second direction; the first sensing universal serial buses are electrically insulated from the second sensing universal serial buses; the conductive repair pattern layers are positioned close to the junctures of the first and second universal serial buses; and the conductive repair pattern layers are electrically floated, and can connect every two adjacent sensing pads after the repair movement finishes.

Description

【Technical field】 [0001] The present invention relates to a panel and its repairing method, and in particular to a touch panel and its repairing method. 【Background technique】 [0002] According to different sensing methods, touch panels are roughly classified into resistive touch panels, capacitive touch panels, optical touch panels, acoustic wave touch panels, and electromagnetic touch panels. Since the capacitive touch panel has the advantages of fast response time, good reliability and high durability, the capacitive touch panel has been widely used in electronic products. According to different structures and manufacturing methods, capacitive touch panels can be roughly divided into two types: surface-mounted and integrated / in-cell. In the surface-mounted capacitive touch panel, the sensing series is usually fabricated on a substrate, and then the substrate with the sensing series is attached to the outer surface of the display. Obviously, the outer The stick-type tou...
