Title:
DRIVING CIRCUIT OF DISPLAY PANEL AND DRIVING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/019866
Kind Code:
A1
Abstract:
A driving circuit of a display panel and a driving device, the driving circuit (1) of the display panel comprising a widening module (10), a control module (20), a bootstrapping module (30) and an output module (40). The control module (20) is electrically connected to the widening module (10), the bootstrapping module (30) and the output module (40). The bootstrapping module (30) is electrically connected to the output module (40). By means of a widening signal generated by the widening module (10), the bootstrapping module (30) may have enough time to charge, which ensures that the output module (40) may reach or exceed a preset potential when receiving the bootstrapping signal, thereby avoiding an unstable voltage when a gate driving signal is outputted and avoiding the gate driving signal stopping output in advance, so as improve the stability of the outputted gate driving signal. Therefore, the refresh rate and the resolution of the display panel are improved, and the display brightness and the stability of the display effect of the display panel are also improved.
