Abstract

The invention provides a touch panel. The touch panel comprises a substrate, a plurality of first electrode pads, a flexible circuit board, a plurality of second electrode pads and conductive adhesives, wherein a plurality of first grooves are formed in the surface of the substrate; the first electrode pads are arranged on the surface of the substrate; the flexible circuit board is arranged corresponding to the surface of the substrate; the second electrode pads are arranged on the surface, facing to the substrate, of the flexible circuit board; the first electrode pads are arranged corresponding to the second electrode pads respectively; the conductive adhesives are arranged between the first electrode pads and the second electrode pads, and are used for enabling the first electrode pads to be electrically connected with the second electrode pads; and the first grooves are filled with at least part of the conductive adhesives. Therefore, the probability of separation of the conductive adhesives or the flexible circuit board is reduced.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular to a touch panel. Background technique [0002] With the development of smart products such as smart phones, touch display devices with displays and touch panels have gradually become mainstream. In the design of the touch panel, in order to effectively use the limited space, the electrode pads of the touch panel are often connected with a flexible circuit board to transmit sensing information. [0003] In order to make the electrical connection between the flexible circuit board and the electrode pads, and to fix the flexible circuit board and the electrode pads to each other, a conductive glue is usually arranged between the flexible circuit board and the electrode pads. Has sticky properties. However, in the manufacturing process or in use, the touch panel or the touch display device is likely to be impacted or pulled, causing the flexible circuit board or the conductive...
