Abstract
An organic light emitting diode (OLED) display includes a pixelated OLED display panel and a color-correction component disposed on the pixelated OLED display panel. The pixelated OLED display panel has a ratio of blue-to-red color mixing weights at 30 degrees of β, and a ratio of blue-to-red color mixing weights at 45 degrees of β, where β≥β≥1.05 and 1.5≥β≥1.1. The color-correction component is configured such that a ratio of blue-to-red color mixing weights at 45 degrees of the display is βand a ratio of blue-to-red color mixing weights at 30 degrees of the display is β, where β−0.1≥β≥2.1−βand β−0.05≥β≥2.05−β. Methods of making OLED displays are described.
