本申请主张在2020年8月9日在中国提交的中国专利申请号No.202010792626.6的优先权，其全部内容通过引用包含于此。
技术领域
本公开实施例涉及集成电路设计领域，尤其涉及一种驱动电压补偿方法、补偿装置及显示装置。
背景技术
液晶显示器(Liquid Crystal Display，LCD)市场竞争激烈，所有厂商都努力提高各项性能，力求性能指标极致化。在LCD的生产制造中，出于电路排布以及结构强度等方面的考虑，显示面板四周需要保留部分非显示区域。这些非显示区域是显示模组边框的重要来源，各大厂商都力求缩减边框尺寸。但是受制于产品工艺，完全消除四周边框是不可能的。
其中一个重要原因是，薄膜晶体管液晶显示器(Thin film transistor liquid crystal display，TFT-LCD)需要控制栅极驱动器，通常布置在屏幕玻璃基板的左侧边缘，这不得不占用一部分空间。为了缩减这部分空间，有开发者将这部分集成电路(Integrated Circuit，IC)安排在显示屏的下边缘，虽然不能完全消除所有边缘空间，但是可以实现上、左、右三边的缩减。但随之而来的问题是，由于IC位置变化，显示屏中控制薄膜晶体管(Thin film transistor，TFT)开关的电路走线必须做出相应调整。变异了的屏幕走线，影响了相关位置的显示性能，会造成显示不均匀的问题。
