A display apparatus comprising: light sources (L1,L2) comprising a first light source and a second light source; a first group of adjacent mono-chrome light filters forming a first plurality of adjacent pixels and a second group of adjacent mono-chrome light filters forming a second plurality of adjacent pixels; a first selective attenuation element positioned between the light sources (L1,L2) and the first group of adjacent mono-chrome light filters, configured to selectively attenuate light from the light sources (L1, L2); a second selective attenuation element positioned between the light sources (L1,L2) and the second group of adjacent mono-chrome light filters, configured to selectively attenuate light from the light sources (L 1, L2); the first group of adjacent mono-chrome light filters comprising: a first mono-chrome light filter defining a first pixel of the first group, overlying the first light source, configured to filter light from the first light source transmitted via the first selective attenuation element; and a second mono-chrome light filter defining a second pixel of the first group, overlying the second light source, configured to filter light from the second light source transmitted via the first selective attenuation element; the second group of adjacent mono-chrome light filters comprising: a first mono-chrome light filter defining a first pixel of the second group, overlying the first light source, configured to filter light from the first light source transmitted via the second selective attenuation element; and a second mono-chrome light filter defining a second pixel of the second group, overlying the second light source, configured to filter light from the second light source transmitted via the second selective attenuation element; a light controller (40, 46) configured to control the first light source to be on in a first time slot and off in a second time slot and to control the second light source to be on in the second time slot and off in the first time slot. light sources (L1,L2) comprising a first light source and a second light source; a first group of adjacent mono-chrome light filters forming a first plurality of adjacent pixels and a second group of adjacent mono-chrome light filters forming a second plurality of adjacent pixels; a first selective attenuation element positioned between the light sources (L1,L2) and the first group of adjacent mono-chrome light filters, configured to selectively attenuate light from the light sources (L1, L2); a second selective attenuation element positioned between the light sources (L1,L2) and the second group of adjacent mono-chrome light filters, configured to selectively attenuate light from the light sources (L 1, L2); a first mono-chrome light filter defining a first pixel of the first group, overlying the first light source, configured to filter light from the first light source transmitted via the first selective attenuation element; and a second mono-chrome light filter defining a second pixel of the first group, overlying the second light source, configured to filter light from the second light source transmitted via the first selective attenuation element; a first mono-chrome light filter defining a first pixel of the second group, overlying the first light source, configured to filter light from the first light source transmitted via the second selective attenuation element; and a second mono-chrome light filter defining a second pixel of the second group, overlying the second light source, configured to filter light from the second light source transmitted via the second selective attenuation element; a light controller (40, 46) configured to control the first light source to be on in a first time slot and off in a second time slot and to control the second light source to be on in the second time slot and off in the first time slot.
