Abstract
A display device comprises a backlight () and a light modulating layer () such as an LCD device. The backlight () 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 () is an OLED device and the 2D/3D mode switching is achieved by selectively energising all or a subset of parallel control electrodes () of the OLED device.
