A reflective polarizer has substantially distinct blue, green and red-infrared reflection bands for substantially normally incident light. A display system includes a display panel including blue, green and red light emitting pixels having respective blue, green and red peak wavelengths and respective blue, green and red FWHMs; and the reflective polarizer disposed on the light emitting pixels. The reflective polarizer: reflects at least about 60% of the incident light for each of the blue and green peak wavelengths and at least about 40% of the incident light for the red peak wavelength for a first polarization state; transmits at least about 60% of the incident light for each of the blue, green and red peak wavelengths for an orthogonal second polarization state; and has an absorption peak at a wavelength between the green and red FWHMs.

Reflective polarizer and display system

Optical film stacks are disclosed. The optical film stacks can include a first reflective polarizer, a second reflective polarizer, and a retardance layer disposed between the first reflective polarizer and the second reflective polarizer.

A backlight includes a light source and one or more light recycling films. The light source generates light that exits the light source with an angular exit distribution. The light recycling films are oriented in relation to the light source so that the prism peaks of the recycling films are oriented away from the light source. The recycling films have a range of optimal incident angles that allow light to pass through the recycling films without recycling. The components of the light source, the characteristics of the recycling films, or both, are configured to control the overlap between the exit distribution of the light source and the optimal incident angle range of the recycling films.

Systems and methods for controlling backlight output characteristics

The present invention provides an optical film composite that includes a linear, reflective polarizing film; a first polymeric substrate layer having birefringence, which is placed on the reflective polarizing film; and a second polymeric substrate layer placed beneath the reflective polarizing film, wherein the optical axis of the first polymeric substrate layer is oriented with respect to the transmission axis of the reflective polarizing film to have of 0&#xb0; to 25&#xb0; of an angular difference between the axes. The optical film composite can be employed in LCD devices to improve optical performance.
