Title: Method for driving liquid crystal lens and device for driving using the same
Inventor: HORIUCHI KATSUJI
IPC: G02F1/133
Filed: 2001-05-18
Abstract: PROBLEM TO BE SOLVED: To provide a method for driving a liquid crystal lens smoothly varying image-forming performance around the time of switching in switching from a driving voltage applied state to a non-applied state (from an on-state to an off-state) and a device for driving using the same. SOLUTION: The method for driving the liquid crystal lens comprises electrically varying a focal distance of the liquid crystal lens 50 with two liquid crystal layers formed between transparent substrates 3, 4 or 3, 5. Using the driving device 1, the method for driving has a voltage applying step to generate an electric field in the liquid crystal layer by applying a static driving voltage thereto so as to align the liquid crystal molecules in the liquid crystal layer and a voltage dropping step to decrease the driving voltage accompanying the lapse of time so as not to produce excessive distribution of a refractive index in the liquid crystal layer and to result in the non-applied state.
