OLED displays are desirable thanks to their deep blacks, excellent contrast, and the enabling of extremely thin and light and even flexible designs. However there are several known drawbacks too; production yields impact on cost, blue pixel life is said to be shorter, and there seems to be a greater potential for burn-in issues. It is that last issue that has been highlighted in recent months by reports of screen issues from owners of the Google Pixel 2 phones, and much more recently by observations of an LG OLED 65-inch TV on show at the SID Display Week 2018 in Los Angeles.
