OLED display

摘要

An OLED display is disclosed, which includes a substrate and a first and a second light emitting unit arranged on the substrate. A first, a second, a third and a fourth region are defined on the substrate, wherein the sub-pixels in the first and fourth regions and the sub-pixels in the second and third regions are symmetrical with each other. Alternatively, the sub-pixels in the first region and the sub-pixels in the third region are point symmetric to a center of the first light emitting unit, so as to improve displaying resolution of the OLED display.

主权项

1. An OLED display, comprising:
a substrate; a plurality of pixel units, wherein each of the pixel unit comprises a first sub-pixel, a second sub-pixel, and a third sub-pixel; a plurality of first light-emitting units, arranged on the substrate in a matrix, wherein a transverse axis and a longitudinal axis intersecting to the transverse axis divide each of the plurality of first light-emitting units into a first region, a second region, a third region and a fourth region, wherein the first and third regions are located at opposite corners of each of the plurality of first light-emitting units, and each of the plurality of first light-emitting units comprises: a first light-emissive layer, corresponding to the plurality of first sub-pixels and overlapping the longitudinal axis; two second light-emissive layers, each corresponding to the plurality of second sub-pixels; and two third light-emissive layers, each corresponding to the plurality of third sub-pixels, wherein one of the second light-emissive layers and one of the third light-emissive layers are respectively disposed in one of the first and fourth regions, and the other second light-emissive layer and the other third light-emissive layer are respectively disposed in one of the second and third regions, and the two pixel units that are adjacent and arranged in a direction parallel to the longitudinal axis, wherein each of the same color sub-pixels in the two pixel units is symmetrical with each other with respect to the transverse axis.
