This is the core part that makes its probes contact with the electrodes of the display (OLED/LCD) panel and applies the electric signals to it to determine whether the panel is defective or not. WithMEMS Co., Ltd. provides differentiated, high-precision test solutions for various display panels through Ultra Film (UF) products and MEMS Blade products based on based on its proprietary Through Polyimide Via (TPV) process technology.
