On the contrary, in the case of flip chip bonding, which is a more advanced method, small bumps called solder balls are attached to the pad of the chip. WebThe main function of the Display Driver Integrated Circuit (DDIC) is to control the OLED display panel. It needs to work with OLED displays to be thin, flexible, and foldable, and to provide a wide color gamut and high-fidelity display signals. At the same time, OLED requires lower power consumption than LCD to achieve higher battery life. OLED ... floating shelves with cables
