Abstract
The present disclosure discloses a pixel detecting circuit, a method for driving the same, and a touch display panel. The pixel detecting circuit includes: a plurality of pixel detecting modules arranged in an array; and at least one reading line, wherein each of the reading line is connected to a group of pixel detecting modules, and each group of pixel detecting modules comprises at least two columns of pixel detecting modules; wherein a number of pixel detecting modules included in each group of pixel detecting modules are respectively connected to different control signal terminals, and configured to transmit, under driving of control signals outputted from the different control signal terminals, electrical signals to the connected reading line in any one of a time dividing manner and a frequency dividing manner.
