Abstract

The invention discloses a liquid crystal display unit and device. A plurality of connecting units are arranged between driving circuit boards and a liquid crystal display panel, every connecting unit comprises at least two tape coiling chips, and the at least two tape coiling chips are arranged in a covering mode and are all connected with the driving circuit boards and the liquid crystal display panel. Through the arrangement of the connecting units, the at least two tape coiling chips are formed on one of the connecting units in a concentrated mode, and accordingly the arrangement space in the extension direction of the driving circuit boards of the tape coiling chips can be reduced to save space, other designs such as the welding design of the tape coiling chips can be facilitated, or the addition of other devices and the like can be facilitated.

Description

【Technical field】 [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display device and equipment. 【Background technique】 [0002] With the continuous development of liquid crystal technology, the requirements for various components in the liquid crystal display device are getting higher and higher. [0003] Chip On Film (COF) packaging structures in the prior art basically use Tape Automated Bonding (TAB) technology for thermocompression packaging of the driver chip, and rolls For reel and feed. In use, each chip-on-flex structure can be sequentially cut from the tape substrate, and electrically connected between a transparent circuit on a glass substrate of a liquid crystal panel and a driving circuit board. There may be one or more flexible chip-on-chip structures between the glass substrate and the driving circuit board. The larger the size of the liquid crystal panel, the greater the number of flexible chip...
