Abstract

The invention discloses a display panel, a control method for the display panel, and a display apparatus. The display panel has a first region and a second region, and comprises multiple first touch electrodes arranged in the first region, multiple second touch electrodes arranged in the second region, an integrated circuit electrically connected with the first touch electrodes and the second touch electrodes, and multiple switch conversion circuit; each switch conversion circuit comprises a common connection end connected with the integrated circuit, a first switch branch with a first end connected with each first touch electrode and a second end connected with the common connection end, and a second switch branch with a first end connected with each second touch electrode and a second end connected with the common connection end; in a first time cycle, the first switch branches are switched on and the second switch branches are switched off; and in a second time cycle, the first switch branches are switched off and the second switch branches are switched on. Through the display panel, fingerprint identification can be realized on the display panel on the premise of not adding a chip pin in the integrated circuit.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display panel, a control method thereof, and a display device. Background technique [0002] In recent years, with the gradual development of touch technology, the display panels of smart phones, smart tablets, smart wearable devices and other devices generally have touch functions. Touch panels can be divided into resistive, capacitive, and optical based on different sensing technologies. , four types of acoustic wave type, among which, the capacitive touch panel determines the touch point by detecting the change of the reference capacitance caused by the inductive capacitance generated between the electrode and the human body. When the human body is not in contact with the touch panel, various electrodes take the current state as a reference value. When the human body touches the touch panel, a parasitic capacitance is generated between the human body and t...
