Patent number: 11093076Abstract: The present invention relates to a design for optimally mounting a Touch Drive (IC) (TDI) signal line and a Display Drive IC (DDI) signal line of a display apparatus having a touch function. According to the display apparatus having a touch function and the method of mounting the signal line of the display apparatus according to the present invention, the TDI signal line and the DDI signal line are mounted so as not to overlap in the bending region on the same flexible substrate, thereby preventing the problem, such as cracks, in the related art. Further, according to the display apparatus having a touch function and the method of mounting the signal line of the display apparatus according to the present invention, it is possible to easily manufacture a full-screen display apparatus by reducing a length of a fan-out area of the TDI signal line.Type: GrantFiled: March 4, 2019Date of Patent: August 17, 2021Assignee: G2TOUCH Co., LTD.Inventors: Hyung Guel Kim, Jong Bae Lee, Ki Hwan Oh, Hwa Joo Noh
