UDC presented a paper on a new technology that reduces power consumption and increases lifespan than the existing RGB-FMM method at SID 2014.

Under the title of “Novel Two Mask AMOLED Display Architecture,’ the paper describes the new technology to reduce to 2 mask from the existing RGB-FMM using 3 mask. In details, each pixel is divided into 2 regions; yellow and blue, and evaporation is performed with the yellow and blue masks. This technology is to form a pixel structure of YRGB by developing a color filter of red and green on the yellow region

UDC describes that the technology reduces the resolution by 33% compare to RGB FMM, but the increase of the blue region will increase the overall lifespan and decrease the power consumption of the display. It also announced that it could lower the production cost by reducing tact time and improving yield rate.

Like UDC, the industry develops various technologies to reduce the yield rate and cost of the AMOLED, and further continuous development of the AMOLED is expected.
