Abstract

本申请涉及一种驱动电路单元、显示驱动电路及显示装置,包括:输入开关晶体管、输出晶体管以及控制晶体管,且输出晶体管中集成有一体电容,通过输入开关晶体管在第一输入信号端的控制下,将第一输入信号端输出的第一输入信号传输给控制节点,并通过控制晶体管在第二输入信号端的控制下,将第三输入信号端提供的栅关闭信号传输给控制节点,使得输出晶体管在控制节点的控制下,基于时钟信号端提供的时钟信号和一体电容提供的电压信号输出栅极驱动信号,且输出晶体管可以通过其内部中集成的一体电容储能,延长输出晶体管打开时间,从而解决了现有相关技术中需要在驱动电路单元中设置额外的电容所导致的成本高问题,降低驱动成本。
