Abstract: The present invention provides a backlight module and a display panel. The backlight module includes a back plate, a light guide plate and a light source. The back plate disposes a reflection layer on an inner surface thereof. The reflection layer and the back plate are integrally formed. A light enters into the light guide plate from a light incident surface of the light guide plate to be projected toward the inner surface of the back plate, then returns to the light guide plate after being reflected by the reflection layer on the inner surface of the light guide plate, and is emitted from a light emitting surface of the light guide plate. The present invention can not be effected by the external influence to cause deformation and other problems, thereby improving the reflection effect.

Abstract: By introducing a stack of alternating high and low index dichroic material layers on the exit surface of a waveguide for a wedge type directional backlight, natural reflectivity differences between polarized components can be increased, effectively reflecting the vast proportion of S-polarized light rays, while at the same time transmitting the P-polarized light rays, of light impacting the exit surface of the waveguide at an angle sufficient to exit the waveguide. This recovers polarization in wedge type backlight systems, increasing illumination exiting the waveguide. Also, on the back reflecting surface of the waveguide, a birefringent material can be added to efficiently transform S-polarized reflected light from the dichroic stack, into returning P-polarized light.

Abstract: 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.
