Description
Technical Field

At present, with the rapid development of smart phones, the larger the smart phone is, the narrower the frame of a display screen is, and more functions are available. Along with the above, the internal structure of the mobile phone is more precise, the space between each module of the mobile phone is more and more compact, and the requirement for the reliability of the mobile phone is higher. In the field of mobile phone display, in order to pursue a larger screen occupation ratio and even a full screen, the best mode for realizing the full screen is based on a COF process (i.e., a driver IC (chip) is fixed on a Flexible Printed Circuit (FPC)) and the display area can be further increased compared with a COG process. COF is a process of directly packaging a chip on an FPC (flexible circuit board), and since the FPC can be freely bent, it can be folded over the back of a glass, thereby achieving the purpose of reducing the lower frame.
