Abstract (en)

[origin: WO2010077363A1] A flat panel display uses pixels (2060) that are turned on or off by the enabling or disabling total internal reflection, TIR, of a light guide (2010). A reflective surface (2070) directs the switched light towards the viewer. An optional mask may be employed to provide extremely high contrast ratios in low and in high ambient lighting conditions. The elements (2080) that enable TIR may be enabled quickly because of their small size and weight, resulting in a very fast switching speed. The fast switching speed allows colors to be generated and displayed in a sequential manner.
