AI Technical Summary
Technical Problem
In traditional TDDI products, the conductive material of the array substrate is prone to sharp corners at the top corners of vias, which can lead to overlap breakage and affect the display effect.
Method used
In touch display devices, touch signal lines and data signal lines are routed overlapping or adjacently in the peripheral area and are directly connected to integrated circuits, avoiding via connections and optimizing the wiring method to save space.
Benefits of technology
This avoids breakage of conductive materials, reduces the resistance of touch signal lines, improves yield, reduces product power consumption, and achieves a narrower bottom bezel.
