CPC G02B 5/287 (2013.01) [H10K 59/35 (2023.02); H10K 59/50 (2023.02)] | 20 Claims |
1. An organic light emitting diode (OLED) display comprising:
a pixelated OLED display panel having a maximum white-point color shift as a view angle varies from 0 to 45 degrees of WPCS045 and a white-point axial efficiency of WPAE0, the pixelated OLED display panel comprising a plurality of pixels, each pixel comprising a plurality of subpixels, each subpixel comprising a plurality of OLED layers; and
a color-correction component disposed on the pixelated OLED display panel, the color-correction component configured such that the display has a maximum white-point color shift as a view angle varies from 0 to 45 degrees of WPCS45 and a white-point axial efficiency of WPAE,
wherein each comparative display panel in a plurality of comparative display panels otherwise equivalent to the pixelated OLED display panel but having one or more different optical thicknesses of the OLED layers has a maximum white-point color shift as a view angle varies from 0 to 45 degrees of WPCSC45 and a white-point axial efficiency of WPAE, the plurality of comparative display panels defining a first performance curve along a boundary of performance points in WPCSC45-WPAEC space,
wherein a plurality of comparative displays otherwise equivalent to the display but having one or more different optical thicknesses of the OLED layers defines a second performance curve along a boundary of performance points in WPCSC45-WPAEC space, the second performance curve being above or to the left of the first performance curve, WPCS45 and WPAE defining a performance point of the display substantially along the second performance curve,
wherein the second performance curve and the plurality of comparative displays defines a third performance curve in WPCSC45-WPAEC space such that for each comparative display in the plurality of comparative displays having a performance point along the second performance curve, removing the color-correction component from the comparative display results in a comparative display panel having a performance point along the third performance curve, the third performance curve being to the right of the first performance curve, WPCS045 and WPAE0 defining a performance point of the display panel substantially along the third performance curve.
