Abstract:
1. An active device array substrate, comprising: a substrate, having a display region and a peripheral circuit region; a plurality of pixel units, disposed in the display region; a plurality of scan lines, disposed on the substrate; a plurality of data lines, disposed on the substrate, wherein the scan lines and data lines control the pixel units; two data testing lines, disposed in the peripheral circuit region; an inner short ring, disposed in the peripheral circuit region, wherein the inner short ring comprises a first segment, a second segment and a connecting segment electrically connecting between the first segment and the second segment; a first active device, having a gate, a source and a drain, wherein the gate and the source connect with the first segment, and the drain connects with the connecting segment; a second active device, having a gate, a source and a drain, wherein the gate and the source connect with the second segment, and the drain connects with the connecting segment; a plurality of third active devices, disposed in the peripheral circuit region, each of the third active devices having a gate, a source and a drain, wherein the gates and the sources of part of the third active devices connect with the first segment, and the corresponding drains connect with the odd scan lines, while the gates and the sources of other third active devices connect with the second segment, and the corresponding drains connect with the even scan lines; and a plurality of fourth active devices, disposed in the peripheral circuit region, each of the fourth active devices having a gate, a source and a drain, wherein the gates of the fourth active devices connect with the connecting segment, part of the sources connect with one of the data testing lines respectively, and the corresponding drains connect with the odd data lines, while the other sources connect with the other one of the data testing lines respectively, and the corresponding drains connect with the even data lines.
