Abstract:
1. A flat display panel, comprising: a substrate having a plurality of pixel units; a first driving line, disposed on the substrate and coupled to a first portion of the pixel units; a second driving line, disposed on the substrate and coupled to a second portion of the pixel units; and an Electronic Static Discharge (ESD) protection circuit, disposed on and around the substrate and electrically isolated from the first driving line and the second driving line, the ESD protection circuit comprising: a first crossing line, crossing over the first driving line and electrically isolated from the first driving line; a second crossing line, crossing over the second driving line and electrically isolated from the second driving line; and a first ESD protection device, electrically connected between the first crossing line and the second crossing line, and disposed between and electrically isolated from the first driving line and the second driving line, wherein when one end of the first ESD protection device receives a voltage larger than a threshold voltage of the first ESD protection device, the first ESD protection device is conducted to release a static electricity from either the first driving line or the second driving line to only the ESD protection circuit in a floating state, wherein the ESD protection circuit is an inner short ring.
