I don't know the update or I'm really confused about the current lifetime of blue oled. But personally I thought about vertical or stacked pixels and its possible problems. I'm really happy now for found about it and here it is.... "The development of vertical or stacked pixels" One facet of all the previous technologies lies in their horizontal arrangement of individual R, G, and B pixels (or sub-pixels). To attain the goal of cramming more pixels into the same amount of physical area, requires moving to some vertical arrangement where the individual RGB elements are stacked on top of one another. Please Register or Log in to view the hidden image! One key to making the vertical pixel rely's on the fact that photons of different energy (e.g. wavelength, color) can penetrate silicon to different levels of depth. Photons with the shortest wavelength have the shortest penetration lengths (due to more interactions with the atoms). So in principle, one can make this kind of pixel device: Please Register or Log in to view the hidden image! The layers are positioned to take advantage of the fact that silicon absorbs different wavelengths of light to different depths. The bottom layer records red, the middle layer records green, and the top layer records blue. Each stack of pixels directly records all of the light at each point in the image. Until recently, this scheme was difficult to engineer on a commercial scale due to various processing problems and the need for the thicknesses of the respective silicon layers to be very precise. This limitations are now over come. Problems with OLED: Lifetime - While red and green OLED films have longer lifetimes (46,000 to 230,000 hours), blue organics currently have much shorter lifetimes (up to around 14,000 hours). That's less than 2 years of continuous use. http://homework.uoregon.edu/pub/class/155/out155/dt2.html And now I think if vertical or stacked pixels have minimum 2 blue layers then it can extend the lifespan of oled screen than before because when a blue layer gonna end its lifetime then another layer can extend the lifespan of oled screen . So I'm waiting for your thought, thanks.
