Abstract:
Disclosed is an imaging directional backlight including an array of light sources, and a control system arranged to provide variable distribution of luminous fluxes, scaled inversely by the width associated with the respective light sources in the lateral direction, across the array of light sources. The luminous intensity distribution of output optical windows may be controlled to provide desirable luminance distributions in the window plane of an autostereoscopic display, a directional display operating in wide angle 2D mode, privacy mode and low power consumption mode. Image quality may be improved and power consumption reduced.

Claim (Index 1):
A method of controlling an array of light sources of a directional backlight that comprises a waveguide having an input end and the array of light sources disposed at different input positions in a lateral direction across the input end of the waveguide, the waveguide further comprising first and second, opposed guide surfaces for guiding light along the waveguide, the waveguide being arranged to direct input light from the light sources as output light through the first guide surface into optical windows in output directions distributed in a lateral direction to the normal to the first guide surface that are dependent on the input positions;\n the method comprising selectively operating the light sources to direct light into varying optical windows, the light sources being controlled by respective drive signals to output light with a substantially desired luminous flux distribution, the respective drive signals configured to compensate for an undesired variation in luminous flux per unit lateral distance across the array of light sources.
