The first substrate has a first electrode layer, and the second substrate has a pixel electrode and a second electrode layer. The driving method includes the steps of: transmitting a first gray level voltage to the pixel electrode; transmitting a first black frame insertion voltage to the pixel electrode; and transmitting a first voltage to the first electrode layer, thereby providing a voltage gap between the first electrode layer and the second electrode layer. Accordingly, the dark-state light-leakage of the blue phase LCD apparatus can be improved.

Abstract: A manufacturing apparatus for liquid crystal (LC) panels, including a temperature control device, an LC status monitor, a backlight source and an ultraviolet set. The temperature control device, on which an LC panel is placed, provides temperature control and is perforated to pass light therethrough. The LC status monitor is operative to observe the LC panel while the light is emitted from the backlight source and transmitted through the LC panel and the temperature control device as back-lights of the LC panel. The ultraviolet set is operative to expose the LC panel to ultraviolet light. The relative position between the temperature control device and the backlight source is adjustable, to switch the operating state of the apparatus. In the first operating state, the LC panel can be observed by the LC status monitor. In the second operating state, the LC panel can be exposed to ultraviolet light.
