摘要： A color shift compensation method, a display panel and a display device are provided. The color shift compensation method includes: acquiring color shift information generated with respect to a test region of a test display panel when the test region is viewed at a first viewing angle, at least a part of first subpixel units within the test region being provided with a test aperture ratio; and controlling, in accordance with the color shift information, at least a part of second subpixel units within a target region of a to-be-manufactured target display panel to be provided with a target aperture ratio being different from the test aperture ratio, to improve color shift within the target region when the target region is viewed at the first viewing angle, wherein a position of the target region on the target display panel is same as a position of the test region on the test display panel, and positions of at least the part of second subpixel units within the target region are same as positions of at least the part of first subpixel units within the test region.

摘要： An optical measurement device and an optical measurement method are provided. The optical measurement device includes a test backplane, a light emitter, a center point detector and a movement device. The movement device is provided on the test backplane, and configured to carry a to-be-tested sample. The light emitter is configured to display a first center point on the to-be-tested sample, and the first center point corresponds to a center point of the test backplane. The center point detector is configured to detect a second center point and display the second center point on the to-be-tested sample, and the second center point is a center point of the to-be-tested sample. The movement device is further configured to move the to-be-tested sample, such that the first center point and the second center point coincide with each other.
