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 pressure responsive electric switch is described having an elongated base containing an electrical switch and terminals. The base is attached to a sensor assembly which actuates and de-actuates the electric switch in response to pressure to be measured. The sensor assembly has a composite actuator member comprising a plurality of stacked snap-acting disc members which includes at least one snap-acting disc member of a chosen low coefficient of thermal expansion and at least one snap-acting disc member of chosen high coefficient of thermal expansion material so as to provide precise pressure activation/deactivation points over a wide temperature range. In a second embodiment, the composite actuator member includes a thermal adjustment member.
