A complementary GOA (Gate Driver on Array) circuit for flat panel display comprises a plurality of cascaded GOA units. The complementary GOA circuit charges an nth-level horizontal scanning line G(n) according to the control of the nth-level GOA unit; the nth-level GOA unit comprises a pull-up circuit module, a pull-down circuit module, a pull-down holding circuit module, a pull-up control circuit module, a pull-down circuit module of an nth-level grid signal point Q(n) and a bootstrap capacitor; the pull-up circuit module, the pull-down circuit module, the pull-down holding circuit module, the pull-down circuit module of the nth-level grid signal point Q(n), and the bootstrap capacitor are electrically connected with the nth-level grid signal point Q(n) and the nth-level horizontal scanning line G(n); and the pull-up control circuit module is electrically connected with the nth-level grid signal point Q(n). The complementary GOA circuit for flat panel display can reduce the size of the pull-down holding circuit module of the GOA circuit to obtain a GOA circuit with reduced size, enabling the GOA circuit to apply to narrow-bezel or bezel-less flat panel display products. |
