'...Now let us talk about proper applications of OLED displays. With the TFT we have a backlight. If the backlight decreases in brightness, the whole display decreases in brightness. With OLEDs we have like every pixel is a backlight, it is emitting light. If we have a lot of pixels next to each other, and we use them, the brightness decreases in according to used time. So, if we have a pixel that is switched on longer than the next pixel, the first pixel will have a little bit lower brightness after some time. In the picture above, you can see two pixels that are moved aside. We cannot see a big difference between them, because they are moved aside. The human eye cannot recognize the brightness very well. We cannot tell what the brightness level of a separate thing is, but we are very good at comparison, and when we move the pixels next to each other we can clearly see the difference between them. This is the case of OLED display that if we have two pixels next to each other there may be some problems, that after some time some of them will have just a little bit lower brightness and we can see the difference....'
