Abstract

The invention discloses an electrical connection structure which at least comprises a first electrical joint, a second electrical joint and a sticking layer, wherein the second electrical joint is provided with at least one projecting structure, the sticking layer is formed between the first electrical joint and the second electrical joint and is used for sticking the first electrical joint and the second electrical joint, and the projecting structure of the second electrical joint penetrates through the sticking layer to contact with the first electrical joint so as to form electrical connection. The electrical connection structure can form unidirectional electrical conduction and jointed fixation, is especially suitable for a technology which can not perform high-temperature lead-tin welding, and can avoid a short-circuit situation caused by transverse conduction.

Description

technical field [0001] The invention relates to an electrical connection structure and an electrical connection method, and in particular to an electrical connection structure and an electrical connection method capable of forming unidirectional electrical conduction and bonding and fixing. Background technique [0002] As the information and communication industries continue to innovate, the liquid crystal display (liquid crystal display; LCD) market is booming. Liquid crystal displays have the advantages of high image quality, small size, light weight, low driving voltage, and low power consumption, so they are widely used in personal digital assistants (personal digital assistants; PDAs), mobile phones, camcorders, notebooks, etc. Consumer communication or electronic products such as computers, desktop monitors, car monitors, and projection TVs. Coupled with the rapid development of integrated circuit (integrated circuit; IC) industry and liquid crystal display manufactu...
