Organic light emitting diode with color-correction for maximum white-point color shift

An organic light emitting diode (OLED) display comprising:

• a 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 blue-point color shift as a view angle varies from 0 to 45 degrees of BPCS45 and a blue axial efficiency of BAE, wherein a first comparative display panel otherwise equivalent to the pixelated OLED display panel but having one or more different optical thicknesses of the OLED layers has a maximum blue-point color shift as a view angle varies from 0 to 45 degrees of BPCSC145 and a blue axial efficiency of BAEC1, wherein BPCSC145 is within 0.0025 of BPCS45 and BAE is at least 10% greater than BAEC1;
• or
• BAEC1 is within 5% of BAE and BPCSC145 is at least 0.005 greater than BPCS45.

A method of making an organic light emitting diode (OLED) display, the method comprising:

• providing an OLED display panel comprising a plurality of pixels, each pixel comprising a plurality of subpixels, each subpixel comprising a plurality of OLED layers, such that each comparative display panel in a plurality of comparative display panels otherwise equivalent to the OLED display panel except for 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 performance curve along a boundary of performance points in WPCSC45-WPAEC space, the performance curve extending from a first endpoint having a lowest acceptable efficiency to a second endpoint having a largest acceptable white-point color shift WPCS45LA, the providing step comprising selecting the optical thicknesses such that the OLED display panel has 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, WPCS045 and WPAE0 defining a performance point of the display panel being to the right of the performance curve, a distance from the performance point of the display panel to the performance curve along a WPCSC45 axis being at least 0.005;
• and
• disposing a color-correction component on the 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, WPCS45 and WPAE defining a performance point of the display being above or to the left of the performance curve.
