Problems solved by technology

After the reliability test is over, the display panel needs to be connected to the drive circuit to realize the display function. At this time, the detection terminal has an electrical signal through the signal line, and forms a chemical reaction with the water and oxygen in the environment, and electrochemical corrosion occurs. When the corrosion is severe , there will be a short circuit in the display panel, resulting in abnormal display of the display panel

Abstract

The invention discloses a display panel, a display device, and a driving method of the display device. The display panel includes a display area and a non-display area, and the non-display area is provided with a detection terminal, a driving signal terminal, a one-way conduction unit, a scan driving circuit, and a driving signal line electrically connected to the scan driving circuit. The drivingsignal terminal is electrically connected to the driving signal line, and the detection terminal is electrically connected to the driving signal line through the one-way conduction unit. If the driving signal terminal transmits a driving signal to the driving signal line, the one-way conduction unit is turned off, the driving signal cannot be input to the detection terminal through the one-way conduction unit, no electrical signal is generated at the detection terminal during a driving process, a chemical reaction between the electrical signal at the detection terminal and the water oxygen inthe environment can be avoided, an electrochemical corrosion phenomenon occurs, the abnormality of the display panel is reduced, and the reliability of the display panel is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technologies, and in particular, to a display panel, a display device, and a driving method for the display device. Background technique [0002] At present, display devices have been widely used in products such as televisions, notebook computers, mobile phones, and personal digital assistants, and display panels are key components of display devices. Many display panels realize display functions by connecting a drive circuit with a package. [0003] Before the display panel realizes the display function, a reliability test needs to be performed on the display panel. During the reliability test, the display panel is electrically connected to the detection terminal through the signal line, and the detection circuit drives the display through the detection terminal for testing. After the reliability test is over, the display panel needs to be connected to the drive circuit to realize t...
