Abstract: The present invention relates to a liquid crystal light valve comprising: a first substrate where a first polymer layer is formed thereon; a second substrate where a second polymer layer is formed thereon, the first polymer layer is opposite to the second polymer; and a liquid crystal material layer filled in between the first polymer layer and the second polymer layer, wherein the first polymer layer and the second polymer layer have a roughened surface, and the roughened surface is disposed between the first polymer layer and the liquid crystal material layer, or between the second polymer layer and the liquid crystal material layer.

Abstract: An interface system of an image-capturing device is disclosed, which is set on a hand-held image-capturing device. The interface system of an image-capturing device includes a display unit, a touch sensor unit, and a control unit. The display unit displays a variety of setting pictures of the image-capturing device. The touch sensor unit senses a touch of a user so as to change the setting pictures displayed on the display unit. The control unit is connected with the display unit and the touch sensor unit, for controlling the operation of the image-capturing device. The disclosed interface system of an image-capturing device enables the user to adjust various kinds of exposure parameters quickly and intuitively.

Abstract: The present invention provides a reflective liquid crystal display assembly, which includes a first substrate, a second substrate and a liquid crystal layer sealed between them. The present invention designs a specific surface structure of at least one of the first and second substrates relative to the liquid crystal layer so that the helical axes of the cholesteric liquid crystal molecules can incline in different directions as desired in the liquid crystal layer. The reflective spectrum can be broadened and the viewing angle is widened.
