(ZH) GOA电路及显示面板
Abstract
(EN)
A GOA circuit (10) and a display panel, wherein a relatively simple circuit design is used to output a negative pulse waveform signal, and a high potential of a clock signal (CK(n)) is changed to a potential of a first high-level signal (VGH1), thereby improving the output capability of the GOA circuit (10); and the GOA circuit (10) is improved by means of a first capacitor (C1) and a second capacitor (C2), such that the GOA circuit (10) is more stable.
(FR)
L'invention concerne un circuit GOA (10) et un panneau d'affichage, une conception de circuit relativement simple étant utilisée pour émettre un signal de forme d'onde d'impulsion négative, et un potentiel haut d'un signal d'horloge (CK (n)) étant modifié à un potentiel d'un premier signal de haut niveau (VGH1), ce qui permet d'améliorer la capacité de sortie du circuit GOA (10); et le circuit GOA (10) est amélioré au moyen d'un premier condensateur (C1) et d'un second condensateur (C2), de telle sorte que le circuit GOA (10) est plus stable.
(ZH)
GOA电路(10)及显示面板,采用较为简单的电路设计输出负脉冲波形信号,且通过改变时钟信号(CK(n))的高电位至第一高电平信号(VGH1)的电位,从而提升GOA电路(10)的输出能力;并通过第一电容(C1)和第二电容(C2)对该GOA电路(10)进行改善,使得GOA电路(10)更加稳定。
