Abstract
One embodiment of the invention includes an image compensation module, an OLED display panel, and an OLED display apparatus. A target current value corresponding to a target gray level is stored in a compensation memory portion. A reference gray level and a reference current value corresponding to the reference gray level are stored in a reference memory portion. A compensation gray level can be obtained by an arithmetic compensation unit according to the target current value, reference gray level, reference current value, and gamma parameter. This may reduce the memory space needed for the compensation and reference memory portions, and compensate the images of the display apparatus and panel so that precise colors can be displayed with a high image quality.
