Beschreibung
Zusammenfassung:	The invention relates to a display panel. The display panel comprises at least one touch sensing pixel and a reading circuit. The at least one touch sensing pixel comprises a first grid line, a sensing line, a touch sensing unit electrically connected between the first grid line and ground voltage, a first transistor electrically connected with the touch sensing unit and the sensing line and a correcting circuit electrically connected with the first transistor and used for providing correction bias voltage for a first transistor grid according to reference voltage and critical voltage. The reading circuit is electrically connected with the sensing line and outputs a touch reading signal by responding to current change of the sensing line.
