[0037] An embodiment of the present invention provides a bootstrap capacitor of a GOA circuit. Please refer to FIG. 2(a) and FIG. 2(b). The bootstrap capacitor includes a first branch capacitor C1 and a second branch capacitor C2. The first The branch capacitor C1 is at the same position on the display panel as the bootstrap capacitor in the prior art, and the second branch capacitor C2 is located above the first branch capacitor C1. Here, the second branch capacitor C2 is located at directly above the first branch capacitor C1, but the present invention is not limited thereto, and in other embodiments of the present invention, the second branch capacitor may also be located obliquely above the first branch capacitor.
[0038] In this embodiment, the second branch capacitor C2 is connected in parallel with the first branch capacitor C1, since the calculation formula after the two capacitors are connected in parallel is: C 总 =C1+C2, that is, the total capacitance after the para...

[0056] Fig. 3 (a) is the schematic diagram of the bootstrap capacitance of a kind of GOA circuit of the second embodiment of the present invention, and the structure of Fig. 3 (a) is the same as Fig. 2 (a), so the same element symbol represents the same part, this implementation The main difference between this example and the first embodiment is the structure of the first branch capacitor and the second branch capacitor.
[0057] Referring to FIG. 3(a) and FIG. 3(b), the bootstrap capacitor includes a first branch capacitor C11 and a second branch capacitor C21, and the second branch capacitor C21 is located above the first branch capacitor C11. Here, the second branch capacitor C21 is located obliquely above the first branch capacitor C11, specifically left obliquely above, of course, in other embodiments of the present invention, the second branch capacitor may also be located at the first branch capacitor C11. Right diagonally above the branch capacitor, etc. In this embo...
