Abstract
A display device includes a light control device, and a backlight having a panel with one or more light management features. The light control device may be a liquid crystal display (LCD), for example having a plurality of picture elements, such as pixels, selectively activatable to allow or black transmission of light through the LCD. The light management features may include one or more features such as a brightness enhancement film, a transflective film, and/or a polarizing film. The backlight has a light emitting structure that may include an electroluminescent structure, such a small molecule organic light emitting device (SMOLED) or a polymer light emitting device (PLED). The electroluminescent structure of the backlight provides good illumination of the light control device at low voltage and low power, and the inclusion of the one or more light management features in the backlight may result in reduction of size, cost, and/or weight of the display device.
