IPC: H01L27/32
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 WPCSC45 and a white-point axial efficiency of WPAEC. 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 WPCS45 and WPCS045 and respective white-point axial efficiencies of WPAE and WPAE0. WPCS045 and WPAE0 defines a performance point of the display panel to the right of the performance curve and WPCS45 and 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.

Abstract: A method of controlling a slot die comprises, while continuing to pass the extrudate through the fluid flow path and out the applicator slot, changing the position of the actuators with the controller to either increase the cross-directional thickness of the fluid flow path adjacent each of the actuators or substantially close the fluid flow path adjacent the actuators, and after changing the cross-directional thickness of the fluid flow path adjacent each of the actuators, while continuing to pass the extrudate through the fluid flow path and out the applicator slot, repositioning each of the actuators with the controller according to the set of discrete settings to resume operating the slot die with the actuators positioned according to the set of discrete settings.
Abstract translation: 一种控制狭槽模头的方法包括：在连续地将挤出物通过流体流动路径并从施加器槽中通过的同时，改变致动器与控制器的位置，以增加流体流动路径的横向厚度 或者基本上关闭与致动器相邻的流体流动路径，并且在改变与每个致动器相邻的流体流动路径的横向厚度的同时，继续使挤出物通过流体流动路径并且从施加器狭槽出来， 根据一组离散设置，使用控制器重新定位每个致动器，以根据一组离散设置使致动器定位，以恢复操作槽模。

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 β030, and a ratio of blue-to-red color mixing weights at 45 degrees of β045, where β045≥β030≥1.05 and 1.5≥β045≥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 β45 and a ratio of blue-to-red color mixing weights at 30 degrees of the display is β30, where β045−0.1≥β45≥2.1−β045 and β030−0.05≥β30≥2.05−β030. Methods of making OLED displays are described.
