Abstract
(EN)
In one example aspect, a device (100) comprises an organic light emitting diode (OLED) display (102, 500). The display comprises a transparent or semi-transparent substrate (510) and includes a first region (104) comprising a plurality of first pixels (300) and a second region (106) comprising a plurality of second pixels (400). A first proportion of each first pixel comprises a first light emissive area (302), a second proportion of each second pixel comprises a second light emissive area (402), and the first proportion is different to the second proportion, wherein the first proportion comprises a ratio of a size of the first light emissive area to a size of each first pixel (300), and the second proportion comprises a ratio of a size of the second light emissive area to a size of each second pixel (400).
