Two-way trans-reflective display

A two-way trans-reflective display pixel ( 100 ) having two viewable sides ( 102, 104 ) is disclosed. The two-way trans-reflective display pixel has a first transparent layer ( 106 ), a second transparent layer ( 108 ), and light modulating medium ( 110 ) sandwiched between them. Both the first and...

Zusammenfassung:	A two-way trans-reflective display pixel ( 100 ) having two viewable sides ( 102, 104 ) is disclosed. The two-way trans-reflective display pixel has a first transparent layer ( 106 ), a second transparent layer ( 108 ), and light modulating medium ( 110 ) sandwiched between them. Both the first and second transparent layers ( 106, 108 ) have light reflectors ( 132, 136 ) and light absorbers ( 130, 134 ), which allow light entering from either viewable sides ( 102, 104 ) to partially reflected, partially absorbed, and partially transmitted, allowing an image to be viewable from both viewable sides ( 102, 104 ). A two-way trans-reflective display ( 402 ) comprising a plurality of two-way trans-reflective display pixels ( 100 ) and a transparent light source ( 412 ) is also disclosed. The transparent light source ( 412 ) provides color light, and enables an image from the two-way trans-reflective display ( 402 ) to be viewable in color from both first and second viewable sizes ( 418, 602 ).
