Abstract
The embodiments of the present disclosure provide a method and apparatus for adjusting gray-scale chromatic aberration for a display panel, as well as a display device. The method comprises: inputting a data signal of a test picture to sub-pixels of the display panel, for causing the display panel to display the test picture; collecting optical parameters of respective regions in the test picture; comparing the optical parameter of each region in the test picture with an optical parameter of a standard picture; and adjusting the data signal inputted to the sub-pixels, such that a difference between the optical parameter of each region in the test picture and the optical parameter of the standard picture falls within a predetermined range. The optical parameter comprises a color coordinate and its corresponding brightness.
