Description

移位暂存电路及其应用的显示面板 技术领域
本申请涉及一种显示器中的电路结构,特别是涉及一种移位暂存电路及其应用的显示面板。
背景技术
近年来,随着科技的进步,平面液晶显示器逐渐普及化,其具有轻薄等优点。目前平面液晶显示器驱动电路主要是由面板外连接IC来组成,但是此方法无法将产品的成本降低、也无法使面板更薄型化。
且液晶显示设备中通常具有栅极驱动电路、源级驱动电路和画素阵列。画素阵列中具有多个画素电路,每一个画素电路依据栅极驱动电路提供的扫秒讯号开启和关闭,并依据源级驱动电路提供的数据讯号,显示数据画面。以栅极驱动电路来说,栅极驱动电路通常具有多级移位寄存器,并藉由一级移位寄存器传递至下一级移位寄存器的方式,来输出扫描讯号到画素阵列中,以依序地开启画素电路,使画素电路接收数据讯号。
因此在驱动电路的制程中,便直接将栅极驱动电路制作在阵列基板上,来取代由外连接IC制作的驱动芯片,此种被称为栅极阵列驱动(Gate On Array,GOA)技术的应用可直接做在面板周围,减少制作程序、降低产品成本且使面板更薄型化。但是现行栅极阵列驱动(GOA)技术的电位下拉是由两组讯号轮流进行控制,工作周期为50%。在此种条件下,负责下拉电位的晶体管会长时间处于正压状态而无法得到充分休息,如此将使得这些晶体管的可靠度快速下降,进而直接造成显示质量的低落甚或显示设备的损坏。因此,如何改善上述习用栅极阵列驱动电路基板技术的缺失,因而提出一种制作成本低且加工容易的移位暂存电路。
