Description

显示数据调整系统及显示数据调整方法 技术领域
本发明涉及显示技术领域，尤其涉及一种显示数据调整系统及显示数据调整方法。
 背景技术
有机发光二极管（Organic Light Emitting Display，OLED）显示装置具有自发光、驱动电压低、发光效率高、响应时间短、清晰度与对比度高、近180°视角、使用温度范围宽，可实现柔性显示与大面积全色显示等诸多优点，被业界公认为是最有发展潜力的显示装置。
OLED显示装置按照驱动方式可以分为无源矩阵型OLED（Passive Matrix OLED，PMOLED）和有源矩阵型OLED（Active Matrix OLED，AMOLED）两大类，即直接寻址和薄膜晶体管（Thin Film Transistor，TFT）矩阵寻址两类。其中，AMOLED具有呈阵列式排布的像素，属于主动显示类型，发光效能高，通常用作高清晰度的大尺寸显示装置。
AMOLED是电流驱动器件，当有电流流经有机发光二极管时，有机发光二极管发光，且发光亮度由流经有机发光二极管自身的电流决定。大部分已有的集成电路（Integrated Circuit，IC）都只传输电压信号，故AMOLED的像素驱动电路需要完成将电压信号转变为电流信号的任务。传统的AMOLED像素驱动电路通常为2T1C，即两个薄膜晶体管加一个电容的结构，将电压变换为电流。对于OLED显示面板，当环境温度增加时，各薄膜晶体管的阈值电压会减小，且迁移率增加，导致流经薄膜晶体管的电流增加，因而在高温环境下使用OLED显示面板，会加速元器件的老化，缩短OLED显示面板的使用寿命，并且由于流经薄膜晶体管的电流增加，导致OLED显示面板实际显示的亮度相较于目标亮度增加，影响显示的效果。
现有技术中，常通过对OLED显示面板的平均图像电平（APL）进行侦测及调节来调整画面亮度以提升其显示效果。
