Problems solved by technology

[0006] As the resolution required by large-scale displays becomes higher and higher, the number of clock signal lines required in the gate drive circuit also increases, so the increase in clock signal lines will cause the leads connected to the clock signal lines to be disconnected from them. The number of parasitic capacitances at the intersection of the clock signal lines increases, which in turn causes an increase in the delay of the clock signal, resulting in an increase in the output delay of the shift register unit and the power consumption of the gate drive circuit

Abstract

The invention discloses an array substrate, a display panel, and a display device. Two adjacent shift register units of the first type and shift register units of the second type are used as a subgroup, and the two shift register units in each subgroup The signal ends of the shift register units used to connect to the same clock signal line are connected through the first lead, and the first lead is connected with the corresponding clock signal line through the second lead. In this way, by adjusting the arrangement sequence of the shift register units or reducing the number of clock signal lines, the overlap between the lead wires and the clock signal lines is reduced, thereby reducing the parasitic capacitance generated at the overlap between the lead wires and the clock signal lines. The number, thereby reducing the delay of the clock signal, and reducing the output delay of the shift register unit and the power consumption of the gate drive circuit.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a display panel and a display device. Background technique [0002] With the rapid development of display technology, displays show a development trend of high integration and low cost. Among them, the GOA (Gate Driver on Array, array substrate row driving) technology integrates the TFT (Thin Film Transistor, thin film transistor) gate switch circuit on the array substrate of the display panel to form a scan drive for the display panel, thus saving The bonding (Bonding) area of ​​the gate integrated circuit (IC, Integrated Circuit) and the wiring space of the fan-out (Fan-out) area can not only reduce the product cost in terms of material cost and manufacturing process, but also make the display panel Aesthetic design with symmetry on both sides and narrow frame; moreover, this integration process can also save the Bonding process in the direction of...
