A luminance adjustment apparatus for a plasma display panel (PDP) is proposed. The luminance adjustment apparatus includes a luminance controller, a gray level shifter and a power controller. The luminance controller outputs a gray level shifting signal and a power adjustment signal. The gray level shifter receives a first luminance video signal and the gray level shifting signal, after the first luminance video signal being level shifted according to the gray level shifting signal, a gray level shifted video signal is output. The power controller is used to receive the gray level shifted video signal and the power adjustment signal, after the gray level shifted video signal being power adjusted by the power adjustment signal, a sub-field controlling signal is output. This enables the preservation of image gradation when adjusting luminance of a video image.

A projector is provided, which includes a red substrate, a green substrate, a blue substrate, an X-cube, an electronic control element, a light guide element, a light valve element, and a projection lens. The red substrate, the green substrate, and the blue substrate respectively illuminate three surfaces of the X-cube, and the light is mixed in the X-cube and then exits from a light emitting surface. The electronic control element controls the red substrate, the green substrate, and the blue substrate. The light guide element is used for reflecting the light from the light emitting surface of the X-cube. The light valve element is used for reflecting the light from the light guide element back to the light guide element, and the light passes through the light guide element and then projected by the projection lens onto a projection plane area. Thereby, the ON/OFF switch time of the present invention is shortened, the temperature may not get over high, the optical efficiency is enhanced, and the whole volume is significantly reduced.

An automotive headlight system and an adaptive automotive headlight system with instant compensation control are provided. The automotive headlight system includes a light source, a total internal reflection prism, a digital reflecting element, a freeform lens, and a multi-curve-reflector. The total internal reflection prism is used for redirecting and reflecting light beams from the light source. The digital reflecting element is controlled to switch to a plurality of states with regard to reflected light beams from the total internal reflection prism then compensation patterns will be promptly given during different states. The freeform lens is used for controlling directions of the light beams from the digital reflecting element. The multi-curve-reflector has a plurality of radii of curvature for reflecting the light beams from the freeform lens. As the automotive headlight system merely uses optical refractive and reflecting elements so that the number of components and cost is greatly reduced as compared with the prior art. Furthermore, the most important is that this invention proposes a new design and instant and personalized compensation solution to reduce more driver's risks.
