How Do PCB Adapter Modules Work?
PCB adapter modules convert display signals from panel-native protocols to host-compatible formats using driver ICs and flexible circuits. They handle timing, power, and data flow for stable visuals. Gesight incorporates automated firmware customization for efficiency.
Driver chips are mounted on the PCB and connected via FPC to the display. Backlights, batteries, and sensors integrate smoothly. In wearables or embedded devices, modules wrap behind panels, managing touch sensing and GUI control. Gesight’s automated production lines handle 10,000 units daily, ensuring scalability.
Core functions include:
-
Signal bridging: Converts MIPI to LVDS or eDP.
-
Power regulation: Maintains stable voltage for panels.
-
EMI shielding: Reduces electromagnetic interference for compliance.
