Patent ID: 8169229

Claim:
An active device array, comprising: a plurality of scan lines, parallel to each other, and a first region and a second region opposite to each other being defined in the extension direction of the scan lines; a plurality of data lines, wherein an extension direction of the data lines intersects the extension direction of the scan lines, and the data lines are located between the first region and the second region; a plurality of pixel structures, located between the first region and the second region, wherein each of the pixel structures is driven by one of the scan lines and one of the data lines; a first testing circuit, located at the first region and electrically connected to the odd scan lines of the plurality of scan lines; a second testing circuit, located at the first region and electrically connected exclusively to the first scan line as well as every (4n+1)th scan line among the plurality of scan lines, wherein n is a positive integer; a third testing circuit, located at the second region and electrically connected to the even scan lines of the plurality of scan lines; and fourth testing circuit, located at the second region and electrically connected exclusively to the second scan line as well as every (4n+2)th scan line among the plurality of scan lines.
