Problems solved by technology

[0004] However, in the prior art, the conductive adhesive used to bond the bonding pad to the control circuit board is simply covered on the bonding pad. After a long period of use, the conductive adhesive may not be able to effectively block moisture or oxygen from entering and contact the bonding pad. , resulting in the corrosion of the bonding pads, causing problems in the transmission of control signals, and causing equipment failures

Abstract

A base plate structure comprises a first base plate, a plurality of first bonding pads and a first bonding layer, wherein the first base plate is provided with an element configuration area and a periphery area; the periphery area is adjacently set on the outer periphery of the element configuration area; the first bonding pads are set on the periphery area at interval; a clearance is set between two adjacent first bonding pads; the bonding layer is set on the first base plate and the bonding layer covers the first bonding pads and the clearances; and the bonding layer adjacent to the element configuration area is provided with a plurality of first arc-shaped edges. After the base plate structure is used for a long time, the bonding layer can effectively prevent moisture or oxygen from entering, thus the first bonding pads are avoided from being rusted and the bonding adhesiveness is better.

Description

technical field [0001] The present invention relates to a substrate structure, in particular to a substrate structure capable of being electrically connected to a circuit board. Background technique [0002] With the advancement of technology, flat panel display devices have been widely used in various fields, such as liquid crystal display devices, which have gradually replaced traditional cathode ray tube display devices due to their superior characteristics such as light and thin body, low power consumption and no radiation. And it is applied to many kinds of electronic products, such as mobile phones, portable multimedia devices, notebook computers or tablet computers, and so on. [0003] Wherein, taking the control of the components on the thin film transistor substrate as an example, in order to transmit the control signal from the external control circuit board to the components on the glass substrate, a bonding pad (bonding pads) is generally arranged at the edge of ...
