Global Mura Compensation (GMC) Technology
OLED is current driven, unlike LCD which is voltage driven. This makes OLED susceptible to current variations. Because a Thin Film Transistor (TFT) is supplying the current, the display’s luminance uniformity is affected by variations in TFT performance. Many pixel-driving technologies, such as current programming and voltage programming, have been developed in the past to correct for this phenomenon. However, none were completely satisfactory.
Kodak’s method, Global Mura Compensation (GMC), detects and compensates for these variations by using an external driver IC. This is far more flexible than previous compensation techniques. This allows Global Mura Compensation to compensate for the variation almost perfectly. Many report that they cannot see any difference between the mura (Japanese word meaning “error”) in OLEDs and the mura in LCDs. Kodak's GMC technology can be used to dramatically improve the yield of OLED manufacturing processes.
