Abstract

The invention provides a display panel which comprises a substrate, an active layer, a gate layer and a threshold voltage adjusting metal layer. The threshold voltage adjusting metal layer is arrangedat the side, away from the gate layer, of the active layer and is connected with the gate layer. When the threshold voltage adjusting metal layer is at a positive potential, the threshold voltage ofa switching thin film transistor is reduced, and the switching thin film transistor is easier to turn on, and when the threshold voltage adjusting metal layer is at a negative potential, the thresholdvoltage of the switching thin film transistor is increased and the switching thin film transistor is stricter to turn off, so that the technical problem of high power consumption of the display panelin the prior art is solved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel. Background technique [0002] At present, for most products, the scan signal end writes a high potential, turns on the switching thin film transistor, and then writes the data signal potential to charge the pixel. In order to ensure that the signal is fully written, the scan signal end potential must be high, so there is a power The problem of consumption, the problem of shortening the usage time of mobile devices. [0003] Therefore, the prior art has the technical problem of high power consumption of the display panel, which needs to be improved. Contents of the invention [0004] The invention provides a threshold voltage adjustment circuit and a display panel, which can regulate the threshold voltage of a switching thin film transistor, so as to solve the technical problem of high power consumption in the existing display panel. [0005] In order...
