Problems solved by technology

[0003] When the existing display panel works in a high-temperature and high-humidity environment, its GOA circuit will output abnormally, resulting in abnormal display of the display panel, and when the display panel displays abnormally, it is impossible to know the abnormal output of the GOA circuit in time, which is not conducive to display panel display. Improvements in display quality

Embodiment Construction

[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0037] The GOA circuit usually includes a multi-level shift register unit, and the output ends of the shift register units at each level are electrically connected to the scanning signal lines one by one, and the enable level of the scanning signal is sequentially output to each scanning signal line to realize step-by-step Line scanning function, so that the display panel presents the corresponding display picture. In the prior art, the time for the display screen to display a frame is a scanning cycle, and the sh...

Abstract

The invention discloses a display panel, a driving method thereof and a display device. The display panel comprises a shift register circuit and at least one detection circuit. The shift register circuit comprises a plurality of shift register units; the plurality of shift register units comprise a scanning shift register unit and a detection shift register unit corresponding to the detection circuit; the scanning shift register unit comprises a first scanning shift register unit corresponding to the detection shift register unit; the scanning input ends of the corresponding detection shift register unit and the first scanning shift register unit are electrically connected with the scanning output end of the previous-stage scanning shift register unit of the first scanning shift register unit; the detection circuit comprises a detection input end, a signal detection module, a signal storage module, a signal output module and a signal output end, the detection circuit can accurately detect the potential of a pull-up node in the detection shift register unit, and then detection of the potential of the pull-up node in the scanning shift register unit is achieved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel, a driving method thereof, and a display device. Background technique [0002] With the development of display technology, the integration of display panels is getting higher and higher, and the cost is getting lower and lower, and the array substrate row drive (Gate Driver on Array, GOA) technology uses GOA technology to integrate the gate driver circuit on the array substrate. The surrounding area of ​​the display device can effectively improve the integration level of the display device and reduce its manufacturing cost while realizing a narrow frame design. [0003] When the existing display panel works in a high-temperature and high-humidity environment, its GOA circuit will output abnormally, resulting in abnormal display of the display panel, and when the display panel displays abnormally, it is impossible to know the abnormal ou...
