COFs TABs are to connect LCD glass and PCB boards, which called X COFs and Y COFs. You know, Sometimes vertical or horizon lines (Like ribbon lines) appeared on the LCD TV screen. One of the reason is the COF TAB broken or disconnecting. In order to solve this problem, if the COF just loose, but still in good condition,We can use TAB COF bonding machine to rebond this COF; if the COF is broken(like chip damage), We can use bonding machine to replace the broken COF with a new COF.

So,the TAB COF Bonding machine is to solve the problems (white screen, black screen, color lines, multi-lines, flowers, vertical semi explicit, etc) caused by TAB COF damage and loose, by pulse heating pressing.It can repair 2k, 4k, OLED,Curved LCD, TV Laptop,etc.

Below are some ribbons lines problem which can be solved by the bonding machine, for your reference.
