Abstract:

An OLED display including a display panel and a color-correction component is described. A plurality of comparative display panels otherwise equivalent to the display panel but having one or more different optical thicknesses of OLED layers have a maximum white-point color shift from 0 to 45 degrees of WPCSand a white-point axial efficiency of WPAE. The plurality of comparative display panels defines a performance curve along a boundary of performance points. The OLED display and the display panel have respective maximum white-point color shifts from 0 to 45 degrees of WPCSand WPCSand respective white-point axial efficiencies of WPAE and WPAE. WPCSand WPAEdefines a performance point of the display panel to the right of the performance curve and WPCSand WPAE defines a performance point of the OLED display above or to the left of the performance curve. Methods of making the OLED display are described.
