Amorphous-silicon gate-driver circuits of shared-node dual pull-down structure with overlapped output signals
— A novel gate‐driver circuit using amorphous‐silicon (a‐Si) TFTs has been developed. The circuit has a shared‐node dual pull‐down AC (SDAC) structure with a common‐node controller for two neighboring stages, resulting in a reduced number of TFTs. The overlapped clock signals widen the temperature r...

| description | — A novel gate‐driver circuit using amorphous‐silicon (a‐Si) TFTs has been developed. The circuit has a shared‐node dual pull‐down AC (SDAC) structure with a common‐node controller for two neighboring stages, resulting in a reduced number of TFTs. The overlapped clock signals widen the temperature range for stable operation due to the extended charging time of the inner nodes of the circuit. The accelerated lifetime was found to be over 1000 hours at 60°C with good bias‐temperature‐stress (BTS) characteristics. Accordingly, the a‐Si gate‐driver circuit was successfully integrated into a 14.1‐in. XGA (1024 × RGB × 768) TFT‐LCD panel having a single bank form. |
