Gray scale compensation method, acquisition device and display panel

The invention provides a gray scale compensation method, an acquisition device and a display panel. The gray scale compensation method is applied to the curved screen, and the gray scale compensation method comprises the steps that the moving track of a shooting unit is determined according to the curvature of the curved screen, and the curvature of the moving track meets the curvature of the curved screen; and controlling the shooting unit to move according to the moving track, controlling the shooting unit to collect a display picture of the curved screen, and performing gray scale compensation on the curved screen on the basis of the display picture. According to the technical scheme, the phenomenon that the brightness of the display screen of the curved screen is not uniform can be effectively reduced. 本申请提供了一种灰阶补偿方法、采集装置和显示面板。其中，灰阶补偿方法应用于曲面屏幕，灰阶补偿方法包括：依据曲面屏幕的曲率确定拍摄单元的移动轨迹，其中，移动轨迹的曲率满足曲面屏幕的曲率；控制拍摄单元按照移动轨迹移动，并控制拍摄单元采集曲面屏幕的显示画面，以显示画面为基础对曲面屏幕进行灰阶补偿。本申请的技术方案能够有效的减少曲面屏幕的显示屏亮度不均匀的现象。
