Abstract
A display device comprises a backlight (6) and a light modulating layer (5) such as an LCD device. The backlight (6) can be controlled to operate as a single homogenous light source for producing 2D images or a series of narrow parallel light sources for producing 3D images. Preferably, the backlight (6) is an OLED device and the 2D/3D mode switching is achieved by selectively energising all or a subset of parallel control electrodes (11) of the OLED device.
Claims16
A display device comprising a light source (6) and an array (5) of light intensity modulators (15) for modulating light from the light source (6), wherein the light source (6) is configured for operation as a single broad light source or a plurality of narrow light sources, spaced in a spacing direction, and the light source (6) and the array (5) are arranged such that each modulator (15) is significantly illuminated by only one of said narrow sources and a string of modulators (15), parallel to said spacing direction, is illuminated by each narrow light source.
