Publication number: 20150303162Abstract: Provided are an IC chip and a display apparatus. The IC chip (109) comprises several conductive metal sheets spaced from each other on one side of the IC chip, and conductive bumps (111) are formed on the conductive metal sheets. According to the present disclosure, since conductive bumps (111) are arranged on the conductive metal sheet of the IC chip (109), it is possible to use a non-conductive bonding layer such as NCF instead of ACF to bond the IC chip (109) to the display panel, and thus no metal particles would accumulate. As a result, the problem of short circuit or too large resistance will not occur. In addition, it is possible to reduce the production cost of the display apparatus by using NCF instead of ACF, facilitating industrialized manufacturing.Type: ApplicationFiled: June 20, 2014Publication date: October 22, 2015Applicants: CHENGDU BOE OPTOELECTRONICS TECHNOLOGY CO., LTD., BOE TECHNOLOGY GROUP CO., LTD.Inventors: Junping BAO, Wei HE, Xinghua LI, Seung Yik PARK
