In this paper, a method of reducing the influence of IR‐drop in OLED display for color gamut mapping (CGM) is described. Due to the IR‐drop, the parameters can be hardly calculated only by formulas, which make the inaccuracy of CGM. This algorithm uses the IR‐drop data of specific gray scale data to find out the IR‐drop rule of arbitrary gray scale. The method is easy and accurate to reduce the influence of IR‐drop, making the CGM better applied to OLED displays.

As we know, OLED has a short lifetime compared with LCD, due to its material characteristic[1], which leads to a fact that improved performance of lifetime in OLED display , especially vehicle OLED products is one of the most important factors in display market development of OLED. In this paper, a novel algorithm for luminance attenuation in OLED was proposed, using the method of statistical regularity.

In this study, the compensation effect of a 7.56‐inch MicroLED product with pure PAM driving scheme is verified using the conventional optical compensation (Demura) method. A theoretical analysis of the overcompensation problem due to the variation of color coordinates of MicroLED devices with luminance is performed. The related phenomenon generates an overcompensation problem of about 10 gray levels at a specific gray level and luminance.
