Embodiment Construction
[0023] The present invention will be further described below in conjunction with accompanying drawing.
[0024] figure 2 The chip-on-film unit 10 according to the present invention in the first embodiment is shown. pass figure 2 It can be clearly seen that the COF unit 10 first includes a soft dielectric layer 11 . The soft dielectric layer 11 is a flexible carrier made of, for example, polyimide.
[0025] A plurality of pins (not shown in the figure) for inputting signals are arranged on the soft dielectric layer 11 , and the soft dielectric layer 11 can be used as a carrier film for these pins to facilitate tape-and-roll transmission.
[0026] Two drive circuit modules are also arranged on the soft dielectric layer 11, namely a first drive circuit module 12.1 and a second drive circuit module 12.2. There is a certain distance between the first driving circuit module 12.1 and the second driving circuit module 12.2, which can be determined according to the process and th...
