Television set, flexible flat cable and manufacturing method thereof

Abstract

The invention provides a television, a flexible flat cable and a manufacturing method thereof. The manufacturing method of the flexible flat cable comprises the steps of: placing a double-layer metalwire on a substrate as a ground wire; using an auxiliary component to pick up, reflex, and fix the upper metal wire of the ground wire; ensuring that the lower metal wire of the ground wire is exposedto a set length; performing gold plating on the exposed portion of the lower metal wire of the ground wire to form a gold finger; removing the auxiliary component, allowing a conductive surface of the reflexed portion of the upper metal wire of the ground wire to be exposed outward, attaching a conductive metal foil to the upper metal wire of the ground wire to allow the conductive metal coil foil to completely cover the reflexed portion of the upper metal wire of the ground wire; gluing the side with the conductive adhesive, of the conductive metal foil and the conductive surface of the reflexed portion of the upper metal wire of the ground wire together to ensure that the upper metal wire of the ground wire is in good electrical contact with the conductive metal foil. The flexible flatcable has better EMC performance and can well meet the needs of practical applications.

Description

technical field [0001] The invention relates to cables, in particular to a flexible flat cable with optimized EMC performance. Background technique [0002] From traditional black and white CRT (Cathode Ray Tube, cathode ray tube) TV to color LCD TV, from standard definition to high definition, from high definition to the current ultra high definition 4K and the upcoming 8K, the progress of various technologies is enough to prove that people's visual sense The pursuit of excitement has never stopped, and as a consumer product, TV must first meet the basic requirements of thin, light and beautiful appearance. [0003] As the resolution increases, the relative data transmission volume also increases. In order to ensure normal display, it is necessary to ensure that the corresponding data transmission is completed within the specified time, which requires the transmission wire to be doubled on the basis of the original data transmission rate. Alternatively, increase the data t...

Problems solved by technology

[0005] As the increase of the transmission rate will make the EMI problem more serious, the traditional way of wrapping the shielding layer on the transmission wire becomes no longer a panacea, and the transmission wire is attached to the common ground (backplane) with tape, which will cause The phenomenon of accumulating water and sparking occurs, and the performance of EMC (Electro Magnetic Compatibility, electromagnetic compatibility) is poor, which cannot well meet the needs of practical applications
