Abstract
A display panel with display and non-display regions has pixel units in the display region. The non-display region defines a bonding region in which there are traces and driving chips. The driving chips are bonded in a flexible printed circuit, and electrically connect with the pixel units. The traces include high-speed signal traces, power traces, and grounding traces. The grounding traces are adjacent to the power traces and so disposed as to shield against electromagnetic interference affecting the signal and power traces, the grounding traces serving as reference ground to the power traces, and form a shield against electromagnetic interference.
