Abstract: The invention provides a CF substrate and an LCD panel. The XF substrate comprises a substrate, and an indium-tin-oxide (ITO) conductive film formed on the substrate; trenches being disposed at edge region of the ITO conductive film, the trenches penetrating the ITO conductive film and dividing the ITO conductive film into a first region and a second region, the first and second regions being mutually insulated. The insulated first and second regions of the CF substrate guarantees the film thickness evenness of the first region so as to guarantee the stable voltage difference of the liquid crystal in the LCD panel for quality display.

Abstract: The invention discloses a new method for controlling lifting force of an aerovane fan and a helicar utilizing this method. The method directly controls airflow rate enter a duct (Collar, culvert pipe, in which has the aerovanes fans), using an airflow valve that can be opening or closed by a rotating operation, so to control lifting force. The airflow valve has double layer perforated the hemisphere hulls or hemi-ellipsoid hulls in shape. A simple and practical helicar is designed on the basis of this method.
