Embodiment Construction

[0014] The present invention will be described in detail below in conjunction with specific embodiments.

[0015] The invention provides a liquid metal graphene composite conductive paste for a transparent display screen, comprising: 20-30 parts of graphene and 70-80 parts of liquid metal, the mixture of graphene and liquid metal in the conductive paste The ratio is 1:3.

[0016] The liquid metal is one of gallium, gallium indium alloy, gallium tin alloy or gallium indium tin alloy. Gallium, gallium-indium alloy, gallium-tin alloy and gallium-indium-tin alloy are all close to glass, can infiltrate the glass, spread along the glass surface and adhere to each other, so they can ensure the adhesion between the glass substrate or film of the transparent display . At the same time, gallium, gallium-indium alloy, gallium-tin alloy, and gallium-indium-tin alloy have strong electrical conductivity, which can meet the transmission of electric energy and electrical signals, and avoid ...

Abstract

The invention discloses a liquid metal graphene composite conductive paste for a transparent display screen, which comprises 20-30 parts of graphene and 70-80 parts of liquid metal. The mixing ratio of the graphene to the liquid metal in the conductive paste is 1: 3. The liquid metal graphene composite conductive paste provided by the invention is used as a connecting welding spot of an LED lamp on a transparent display screen and a metal wire on conductive glass to realize electrical connection between the LED lamp and the metal wire, and compared with the prior art, the conductive performance and the heat dissipation performance are improved, so that the electric signal transmission requirement of a large transparent display screen is met, the heat dissipation performance is improved, and the situation that the service life of the transparent display screen is affected by a large amount of heat generated by long-time work of the LED lamps is avoided. Meanwhile, the liquid metal is close to the glass substrate and can infiltrate the glass substrate, so that it is guaranteed that the liquid metal can be stably attached to the glass substrate, and the transmission requirements of electric energy and electric signals of the LED lamp are met.

Description

technical field [0001] The invention relates to the technical field of transparent display screens, in particular to a liquid metal graphene composite conductive paste for transparent display screens. Background technique [0002] LED transparent display is a high-end customized photoelectric transparent display that uses transparent conductive technology to glue the LED structure layer between two layers of glass or film. It retains the easy control, low-voltage DC drive, and combination of traditional LED displays. In addition to the advantages of rich color expression and long service life, it also provides transparent texture, wire-free appearance and bright light. It is also widely used in urban lighting projects and large-screen display systems due to its unique advantages in the application of glass curtain walls. At the same time, it can be used as an indoor display curtain wall, and is widely used in large square lighting, stage scenery, bars, high-end dance halls,...
