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 display system for sensing a finger of a user applied to the display system includes a display panel; a sensor for sensing the finger; a sensing light source configured to emit a first light having a first wavelength W1; and a reflective polarizer disposed between the display panel and the sensor. For a substantially normally incident light, an optical transmittance of the reflective polarizer versus wavelength for a first polarization state has a band edge such that for a first wavelength range extending from a smaller wavelength L1 to a greater wavelength L2 and including W1, where 30 nm?L2?L1?50 nm and L1 is greater than and within about 20 nm of a wavelength L3 corresponding to an optical transmittance of about 50% along the band edge, the optical transmittance has an average of greater than about 75%.

Abstract: A device for externally covering a rear vehicle light for protection from obscuring snow or dirt is provided. The device comprises a support structure to position a transparent cylindrical cover over a rear vehicle light. The cover is rotated by an electric motor. Also affixed to the support structure are upper and lower wiper blades in contact with the surface of the cover. While the cover is rotating light diminishing dirt and slush is scraped off the cover surface by the wiper blades.

Abstract: A safety guard is provided for preventing a wheel from coming off the body of a vehicle. The safety guard includes a first attachment releasably secured to the body on one side of the wheel and a second attachment releasably secured to the body on a transversely opposing side of the wheel. A restraining member is removably secured in a transversely slidable engagement with and between the first and second attachments and immediately adjacent an outer face of the wheel so as to prevent movement of the wheel away from the body.
