Organic light emitting diode display with color-correction component
摘要
說明書
There is typically a largest acceptable maximum white-point color shift for view angles from 0 to 45 degrees of WPCS45LA 220 and a minimum acceptable axial efficiency WPAEMin 230 that may depend on the application (e.g., one or both quantities may be different for cell phones than for televisions). In some embodiments, the plurality of comparative display panels has a range of WPCSC45 that extends both below and above WPCS45LA. In some embodiments, a range of WPCSC45 extends at least from 0.01 to 0.015. In some such embodiments, the range of WPCSC45 extends to at least 0.02, or at least from 0.009 to at 0.015, or at least from 0.008 to 0.02, for example. If one were to choose a performance point without reference to a hybrid color-correcting component, one would choose a point 213 along the performance curve 210 having a white-point axial efficiency greater than WPAEMin and having a maximum white-point color shift for view angles from 0 to 45 degrees less than WPCS45LAIn some embodiments the WPAEMin is at least 25 cd/A, or 30 cd/A, or 35 cd/A, or 40 cd/A.
According to the present description, it has been found that designing the OLED panel to consider the effects of the hybrid color-correction component can provide improved results compared to using a hybrid color-correction on a conventionally designed OLED panel. Since we are interested in optimizing the results for the display having the hybrid color-correction component disposed on the display panel, the optimum choice for the performance point of the display panel may be below and to the right of the performance curve 210, though in some cases it may also be on the performance curve 210.
