Abstract: A display device including a substrate, a light absorption layer, an optical matching layer, a first transparent electrode, a light emitting layer, and a second transparent electrode is provided. The light absorption layer is disposed on the substrate, and the optical matching layer is disposed on the light absorption layer. The first transparent electrode is disposed on the optical matching layer, the light emitting layer is disposed on the first transparent electrode, and the second transparent electrode is disposed on the light emitting layer. An output luminance and a reflectance of ambient light are controlled by adjusting refractive indices of the optical matching layer and the light absorption layer.

Abstract: The disclosure provides a display backlight unit and its light down conversion film. The light down conversion film may include a quantum-dot layer sandwiched between input substrate and an exit substrate. First and second refractive asymmetric micro-prisms are disposed on two opposite input and first exit surfaces of the input substrate, respectively. On the input surface of the input substrate, multiple arrays of the asymmetric refractive asymmetric micro-prisms preserve the large off-axis angle of incident light with first wavelength. On the first exit surface of the input substrate, multiple arrays of the refractive asymmetric micro-prisms increase the reflectance of the large incident angle light. A second exit surface of the exit substrate includes refractive symmetric micro-prisms. The refractive asymmetric micro-prisms of the input substrate and the refractive asymmetric micro-prisms of the exit substrate have rounded tips and valleys for enhancing refraction of the first light and the second light.

Abstract: A display panel includes a first substrate, a second substrate, a liquid crystal layer interposed between the first substrate and the second substrate, a color filter layer, a first pixel unit, a second pixel unit, and a third pixel unit. The liquid crystal layer includes optically isotropic liquid crystals. The first pixel unit, the second pixel unit and the third pixel unit form a first electric field, a second electric field and a third electric filed in the liquid crystal layer. A first display light, a second display light and a third display light displayed by the first pixel unit, the second pixel unit and the third pixel unit have different wavelengths. The first electric field, the second electric field and the third electric field are different when the first pixel unit, the second pixel unit and the third pixel unit are applied by a same driving voltage set.

Abstract: An optical film and a display assembly applying the optical film are provided. The optical film may comprise a plurality of truncated tapered units embedded in a material layer for transmitting a light emitted from the display unit by reflecting the light through a reflection surface between the truncated tapered units and the material layer, wherein a ratio of the area of a first end surface where the light emerges from each truncated tapered unit and the area of a second end surface where the light is incident into each truncated tapered may be between 0.2 and 0.6. Furthermore, a light absorbing layer may be formed on a light output side of the optical film for absorbing ambient light.
