With their crisp images and striking contrast,organic lightemitting diode(OLED)displays with hundreds of pixels per inch(ppi)have become the screen technology of choice for most smart phones and many high-end televisions(TVs)[1].But some applications,especially improved virtual reality(VR),augmented reality(AR),and mixed reality(MR)devices will require higher pixel densities than current OLED displays provide[2].In late 2020,researchers at Stanford University in Palo Alto,CA,USA,and the Republic of Korean company Samsung described a design that yields more than 10000 ppi,an OLED record[3].The discovery could allow development of a variety of new OLED-based electronics.However,experts caution,technical constraints and competition from other types of displays could curb adoption of such very high-resolution OLED screens.
