Abstract:
1. A transflective liquid crystal display device ( 700 , 800 ) comprising: a liquid crystal layer ( 712 ), a transflector ( 713 ), a polarizing means ( 704 ), and a backlight ( 705 ), sandwiched in said order; said backlight ( 705 ) being operative to emit light towards said transflector ( 713 ), and said transflector ( 713 ) being transmissive for a first part of said light and non-transmissive for a second part of said light wherein said transflector ( 713 ) is of a hole-in-mirror type comprising at least one portion that is non-transmissive for light, and at least one portion that is transmissive for light; said display device ( 700 , 800 ) further comprising a depolarizing means ( 714 ) arranged between said transflector ( 713 ) and said polarizing means ( 704 ); said depolarizing means ( 714 ) being operative to selectively depolarize said second part of light by randomly polarizing said second part of light, thereby enabling parts of said second part of light to be transmitted through said polarizing means ( 704 ) and to be recycled in said backlight ( 705 ).
