Patent ID: 8749475

Claim:
A pixel array, comprising: a plurality of scan lines and a plurality of data lines disposed crossing the scan lines to define a plurality of sub-pixel regions; at least one controlling structure disposed in one of the sub-pixel regions and electrically connected to one of the data lines and one of the scan lines; a plurality of sensing signal lines disposed parallel with the data lines and crossing the scan lines, wherein each of the sensing signal lines, one neighboring data line of the plurality of data lines, and the corresponding at least two scan lines of the plurality of scan lines define one of a plurality of regions each having at least one first sub-region and at least one second sub-region, a first region of the plurality of regions is disposed in a first column, a second region of the plurality of regions is disposed in a second column, a third region of the plurality of regions is disposed in a third column, and the sensing signal lines and the data lines are physically different lines; at least one sensing-signal readout device of a plurality of sensing-signal readout devices disposed in the at least one first sub-region, wherein the at least one sensing-signal readout device is electrically connected to one of the scan lines and one of the sensing signal lines, wherein the sensing-signal readout devices disposed in the first column, the second column and the third column are not aligned in the same row with each other, wherein the first column is adjacent to the second column, and the third column is adjacent to the second column; and at least one first sensing pad disposed in the at least one second sub-region and electrically connected to the at least one sensing-signal readout device in the at least one first sub-region.
